Injection molding

1 Basic facts and strategies

injection molding zh s chng xnginjections Molding

The injection molding process can be roughly divided into the enumerated below 6 steps

procedure molding



message:

Clamping, injections, duress keeping, a / c, Mold entrance, And product excretion.

By repeating adore the look process, numerous be produced periodically in batches. The molding of thermosetting plastics and rubber also includes hassle,unchanged process, But the barrel temperatures are lower than that of thermoplastics, The procedure pressure is higher, The mold is warmed up, And the material needs to be cured or vulcanized in the mold after injection, And then the film is removed while hot.

in these modern times, The trend of processing technology is developing towards high-specialist. These devices include: small-injection, elevated-Fill compound hypodermic injection, water-Assisted injections, Mixed use of various special injection molding processes, Foam shot, Mold systems, Simulation technology, and so on.

2 historical past

on 1868, Hayart developed a nasty, which he named celluloid. Celluloid was designed by Alexander Parks in 1851. Hayart improves it so that it can be processed into finished shapes. Hayat and his brother Isaiah recorded the right of the plunger injection machine in 1872. This machine is fairly simpler than the machine used in the 20th century. It ultimately behaves like a huge hypodermic needle. This huge hook (Diffusion tube) Injects plastic into the mold via the heated cylinder.

in their 1940s, The Second World War created a huge interest on cheap, large-Produced remedys., discount-be, mass fast-Produced programs.

throughout the 1946, The American inventor James Watson Hendry built an hypodermic injection molding machine, Which allowed more control over the injection speed and company's produced items. The machine also mixes the type of material before injection, So that the colored or plastic can be thoroughly mixed and injected into the original material. A screw injection machine was developed within the in 1951. this didn't apply, And flow is still in use.

in their 1970s, Hendry then created a gas-Assisted injection molding process and allowed producing complex, Hollow products that cooled quickly. This greatly improves design flexibility along with strength and finish of manufactured parts, While reducing development in the body time, charges, free weight and waste.

3 injection molding process



environment control

hypodermic injection molding equipment and molds



Barrel heat: The heat to be controlled during the injection molding process includes barrel local climate, Nozzle temps and mold local climate. The first two temp mainly affect the plasticization and flow of plastics, While the latter environment mainly affects the flow and cooling of plastics. Each plastic has a different flow temp. for the same plastic, Due to be able to sources or brands, Its flow temperature and decomposition temperature are wide and varied. This is due to the difference in average molecular weight and molecular weight distribution. Plastics are injected in different types. The plasticizing process in the slicer is also different, So the temperature of the chosen barrel is also different.

Nozzle temp: The nozzle temperature is usually slightly lower than the high temperature of the barrel. This is to stop the 'salvation phenomenon' of the molten material in the straight-using nozzle. The temperature of the nozzle truly too low, Otherwise it can cause premature coagulation of the melt and block the nozzle, Or affect the performance of the merchandise due to the injection of the early coagulation into the mold cavity.

Mold environment: The mold temperature has a great influence on the internal performance and apparent excellence of the product. The hotness of the mold depends on the crystallinity of the plastic, The size and structure of the web template, Performance benchmarks, And other process circumstances (Melt local climate, injection speed and shot pressure, molding cycle, and a lot more.).



amount of pressure control

the stress in the injection molding process includes two kinds of plasticizing pressure and injection pressure, And directly affects the plasticization of pockets and product quality.

Plasticizing pushing: (Back stress) the screw-Type hypodermic injection machine is used, The pressure at the top of the screw when the screw rotates backwards is called the plasticizing pressure, also back pressure. the magnitude of this pressure can be adjusted through the relief valve in the hydraulic system. In injection, The plasticizing pressure needs to be changed depending on the screw design, Product quality prerequisites, And revoltions per minute rating plastic. If these cases and the screw speed are unchanged, helping the plasticizing pressure will strengthen the shear. The effect is to boost the temperature of the melt, But it will reduce the efficiency of plasticization, improve counterflow and leakage, And expand the driving power.

aside from that, increasing the plasticizing pressure can often make the temperature of the melt uniform, the blending of the color material uniform, And emit the gas in the melt. widespread

Pressure curve in injections molding



functioning, The decision of plasticizing pressure should be as small as possible on the premise of ensuring good product quality. the suitable value varies with the type of plastic used, But more often than not rarely exceeds 20 kg / cm2.

treatment pressure: nowadays in this production, The injection pressure of almost all injection machines is depending on the plunger or screw top against the plastic

The applied pressure (modified from the oil pressure) Shall triumph. The role of injection pressure in injection molding is to overcome the flow resistance of plastic from the barrel to the cavity, Give the molten material a filling rate and compact the molten material.

injections molding





molding cycle

The time required to do an injection molding process is called the molding cycle, named the molding cycle. It actually includes in this article parts:

injection molding cycle



molding cycle: The molding cycle directly affects labor generating and equipment utilization. thence, In the production process, On the premise of ensuring the coffee quality, Try to shorten established track record time in the molding cycle. In your whole molding cycle, The injection time and cooling time are crucial, And they have a decisive influence on human eye the product. The filling time in the procedure time is directly inversely proportional to the filling rate, And the filling time in production is invariably about 35 seconds. the pressure holding time in the injection time is the pressure time for the plastic in the cavity, Which is in charge of a large proportion of the entire injection time, actually about 20120 seconds (Up to 510 minutes for really thick parts). prior to a frit is frozen at the gate, The holding time will affect the truth of the product size. should it be later, it has no effect. The holding time also has an improvement, Which is known to depend on martial arts temperature, Mold temps, And the length of the main channel and gate. If the scale of the main channel and gate and the process conditions are normal, The pressure value that results in a small fluctuation range of the shrinkage rate of the product is usually typical. The cooling time mainly depends on density of the product, The thermal and crystalline belongings of the plastic, And the mold temp. The end of the cooling time should be based on the principle of ensuring that the product does not cause changes when demoulding. The cooling time will likely be about 30120 seconds. If the cooling time is extended periods, It is not needed. not only does it reduce production efficiency, it will also cause release of complex parts. it is difficult to mold, And even demoulding stress may be gained during forced demoulding. The other time in the molding cycle is related to whether manufacturing process is continuous and automated and the degree of continuous and automated.

4 guidelines

injection pressure

The injection pressure is provided by the hydraulic system of the injection system. the stress of the hydraulic cylinder is transmitted to the plastic melt through the screw of the injection molding machine. Under the stress of the plastic melt, The plastic melt enters the vertical flow path of the mold (the biggest flow path for some molds), a vey important flow path, And the split flow And enter the mold cavity along with gate. this method is called injection molding, Or filling. pressure exists to overcome the resistance in the melt flow process, Or having said that, The resistance in the flow process needs to be offset by the pressure of the injection molding machine to make certain the filling process proceeds smoothly.

through the injection molding process, The pressure at the nozzle of the injection molding machine is high to overcome the flow resistance over the melt. until it is gone, pressure gradually decreases along the flow length toward the wave front of the melt front. If the exhaust the ambani house mold cavity is good, the stress behind the melt front is the atmospheric pressure.

there's a lot of factors that affect the filling pressure of the melt. There are three categories all together: alloy factors, including type and viscosity of the plastic; structural factors, just like the type, Number and placement of the casting system, The cavity form of the mold, And density of the product. ; Forming process temperatures.

injections time

The injection time mentioned here refers back to the time required for the plastic melt to fill the cavity, Excluding auxiliary time such as mold rasing and lowering. although the injection time is very short and has little effect on the molding cycle, The adjustment of the injection time has a great effect on the stress control of the gate, athlete and cavity. cheap injection time helps the melt to fill ideally, And one must always to improve the surface quality of the product and reduce the dimensional tolerance.

The injection time is lower than the cooling time, which happens to be about 1/101/15 of the cooling time. This rule may be used as the basis for predicting the total molding time of plastic parts. In the mold flow analysis, The injection time in the analysis result is equal to the injection time set in the way conditions only when the melt is completely driven by the rotation of the screw to fill the cavity. If pressure retention switch of the screw occurs before the cavity is filled, The analysis result will be much more than the setting of the process conditions.

Injection warm

Injection temperature is key point affecting injection pressure. The shot molding machine barrel has 56 heating sections, And each raw material has its proper processing heat range (Detailed processing temperature can refer to the data provided by the fabric supplier). The injection heat must be controlled within a certain range. If the temperature is too low, The melt plasticization is going to poor, Affecting the products the molded parts and increasing the difficulty of the process; If the temperatures are too high, The rock will be easily decomposed. In any injection molding process, The injection temperature is often higher than the barrel temperature, And the higher value is related to the injection rate and the performance of the material, a lot of 30. This is due to the high heat generated when the melt is sheared when passing along with injection port. There are two ways to complete this difference when doing mold flow analysis. One is to try to measure the hotness of the melt injection molding, And the other is to add the nozzle during modeling.

Holding trigger and time

Near the end of the shot molding process, The screw stops turning and only advances, At which time injection molding enters the pressure holding stage. During the pressure maintaining process, The nozzle of the injection molding machine non-stop replenishes the cavity to fill the volume vacated by the shrinkage of the parts. If the stress is not maintained after the cavity is filled, The part will decrease about 25%, particularly the ribs will shrink due to excessive shrinkage. The holding pressure will be about 85% of the filling pressure, Which of course should be determined using the actual situation.

Back trigger

Back pressure refers to the pressure that the screw needs to overcome when reversing the storage material after reversing the screw. including high back pressure is conducive to the dispersion of the colorant and the melting of the plastic, but it extends the screw retraction time, Reduces the capacity of the plastic fiber, And enhances the pressure of the injection molding machine. 20% of anxieties. When shot molding foam, The back pressure should be higher than pressure created by the gas, Otherwise the screw will be pushed outside the barrel. Some injection molding machines can program the back pressure to make up for the reduction in the length of the screw during melting, Which reduces the input heat and lowers the temperature. anyhow, Because the end result of this change is difficult to estimate, it is not easy to make corresponding adjustments to the machine.

5 Defect resolution

The injection molding process is a complex factor regarding mold design, Mold construction, Raw material attributes and raw material pretreatment methods, Molding job, Injection molding machine action, and the like, And is closely related to processing external conditions, pill cooling time, And information-treatment process. making processes. then, The company's product is not only determined by the injection accuracy and measurement accuracy of the injection molding machine, Or only by products you can the mold design and the accuracy level of the mold processing. actually, It will also be affected by the other factors already mentioned and Constraints.

Under the regulations of so many compound factors, the appearance of defects in injection molded products is inevitable. outcome, The internal mechanism of defect generation and the place and type of defects that can be produced by the product are predicted, And used to guide mold design and enhancer, And summarize defects The law of production and the formulation of more reasonable process operating conditions are particularly important. We will elaborate the mechanism and solution of injection molding defects from three main factors that affect the plastic material characteristics, Mold format, injections molding process and hypodermic injection equipment in the hypodermic injection molding process.

Common defects group of injection molded products

The plastic material goods used in the injection molding process are diverse, And the kinds and forms of mold design are also varied. besides, The operator's familiarity with the specific injection molding machine, As well as the operating skills and practical experience of the workers, Are also countless. at the same time, the goal environment (Such as ambient setting, humidity, And air practices) Will also vary with the times of year. These objective and subjective conditions jointly determine the occurrence of defects in injection molded products.

as a rule, There are three main aspects of evaluating the stage production of plastic products:

, appearing quality, Including self-respect, shade of, gloss;

Second, the accuracy between size and relative position, might, dimensional accuracy and position accuracy;

Third, The mechanical features, Chemical rentals, Electrical units, and more. comparable to the purpose, it is, efficiency

like a result, If a problem occurs due to any of this three aspects, It will resulted in the occurrence and expansion of product defects.

5 institution method of mold silicone rubber

1. The silica gel plus the curing agent are stirred evenly. the look off the mold silicone is a flowing liquid, piece A is silica gel, And contributing factor B is the curing agent. example: Take 100 grams of it gel and add 2 grams of curing agent. Will affect the service life of silicone molds and the amount mold overturns, and even cause the mold to be scrapped.

2 Vacuum exhaust bubble treatment solutions: following a silica gel and the curing agent are evenly mixed, complete the vacuum exhaust bubble link. The time of vacuum extraction actually too long. Under normal reasons, Do not exceed 10 no time at all. The vacuum time is long, The silicone will cure in no time, A upset-Linking reaction is generated, Making the plastic pieces piece by piece, Which can not painted or poured, in order that the silicone is wasted, And the silicone can only be poured into the rubbish bin, And the plastic is taken again.

3 Brushing or functions process: The silicone that is evacuated together with air bubble is brushed or poured. Pour on the solution (email: the information or model to be copied before pouring the silicone must be released with release agent or release agent). Then apply the silicone to the. the application form must be even. After 30 additional units, Paste a layer of gauze fiber weft to increase the strength and tensile strength of the silicone. Then apply another layer of silicone, after which they are paste a layer of gauze fiber weft cloth, So that after two times, it can be fine. Only everyone knows, The service life and how much mold turning times of the silicone molds to be opened are relatively much improved, Which can save costs and get considerably more rate.

4 producing the outer mold: the typical method and material is to surround the mold with rubber plates or wooden boards.

creating

1 basic class

Different plastic molding methods require the use of molds with different principles and structural attributes.

shot molding mold: Plastic is heated and melted in the heating cylinder of the injection molding machine, And then driven by the screw or piston of the injections molding machine, It enters the mold cavity through the nozzle and the casting system of the mold, then hardens and sets in the cavity. the straightforward process of molding, And the mold used for injection molding is named injection molding mold. The injection mold is mainly used for the molding of polycarbonate plastic products, But massive it has also been increasingly used for the molding of thermosetting plastics. Injection molding occupies a huge share in the molding of plastic products, So about half of producing plastic molding molds are injection molds.

Extrusion mould: otherwise known as the machine head. Let the plastic in viscous state suffer a die with a specific cross-Sectional shape under warm and high pressure, And then cool and set at a lower temperatures. The molding method used to produce a continuous profile with the desired cross-Sectional shape is referred to as extrusion molding. The mold used for plastic extrusion is an extrusion mold.

knock back-Molding mold for hollow pieces: Put the tubular blank that is extruded or injected into the mold cavity even though it is hot, And immediately put compressed air involved with the blank to expand the tube blank and adhere to the mold After cooling and hardening, The cavity wall becomes a hollow application. The mold used in this molding method a hollow product blow molding mold.

Vacuum or compressed air forming mold: This is an independent female or male mold. squash the pre-Made plastic sheet tightly through periphery of the mold, Heat it to melt it, And then evacuate on the side towards the mold, Or fill the compressed air on turned around side to make the plastic sheet adhere to the mold; Cool and set Then I got the information. The mold of this molding method has less stress and low standards, And be also made of non-Metallic substance.

data compresion molding mold: recognised as compression mold. Add the plastic recycleables directly into the open mold cavity, just to close the mold. The plastic becomes fluid and fills the cavity under the action of heat and pressure; then your plastic is hardened and shaped due to chemical or physical changes. but not especially is called pressing. creating, And the mold used is called a compression molding mold. Most of these molds can be used molding thermosetting plastics, but also for thermoplastics. besides, you do have a non-warmed up cold-Press creating die, which is often used to mold PTFE blanks.

die-throwing mould: otherwise known as transfer mould. vinyl is added to the preheated feed chamber, And then pressure is applied to pressure column. The plastic melts under temperature and pressure and enters the cavity through the mold pouring system. It is little-by-little hardened and molded. This molding strategy is called die casting molding. The mold used rang die-throwing mold. these sort of mold is mostly used for molding thermosetting plastics.

marketing and sales experience, you can utilize foam plastic molding molds, Glass fiber strengthened plastic low-Pressure molding molds along with.

2 main complications



Height resetting

1. Due to the actual in the closing height of the CNC punch, if you wish to prevent accidents, The mold is in a short state with regards to leaves the factory. 2. First loosen the lock screw of the show up head nut; 3. Turn the strike head nut for change, gauge the rough height with a caliper, immediately after which it fine-beat; 4. Repeat to adjust to the suitable height, And then tighten the lock screw before lock nut That's it.

version dirt

A cured with elastomeric hybrid molds is mold dirt. Mold fouling is an inherent tendency of the mixture to stick to the mold surface during processing. The degree of fouling of the mold will become a thin layer of mucous deposited on the top of mold. Mold fouling not only leads to a decrease in production efficiency, But also increases the scrap rate. Production is affected because parts end up being moved more carefully, And the molds are cleaned gradually, leading to lost production time. the increase in scrap is caused by the in-Mold defects attributed to the cracking of parts in the mold and the disposal of the mold.

3 Dirt treatment plan

there's a lot of different methods for forming molds to improve mold dirt in elastomer rubber synthesis. These models include internal release mold release agent, external mold release agent spray, Mold surface treatment and befitting process parameters. The more effective method is to use these methods adequately.

it's crucial that all elastomer mixtures in the model have at least one internal release release aid. These internal release aids will be wax, Oleic acid solution, Phosphoric acid or other low molecular weight compounds that move to the outer during the molding process and form a protective film on the molding surface. Although fantastic, Adding too much internal release aid will cause the aid to accumulate on the mold surface to form dirt.

The external release agent spray is automobile overnight internal additives, But it is sprayed directly on the top of mold before the part mold. They may also cause the adverse side effects of mold fouling due to excessive spraying. The outward release agent spray can be semi-permanent, Reducing the regularity of spraying and potential excessive accumulation. in modern times, Most reagents containing water are mainly containing silicon or fluorine.

The surface treatment method of the mold helps to protect the material from abrasion during processing. it gives you anti-Corrosion is effective through various chemical reagents and by-Products during the treatment process, Prevents the corrosion of caffeine reagents, and offers smooth and non-Porous quality for the components. pattern dirt. Chromium nickel plating has been widespread. Teflon, Silicon carbide and professional-Grade nickel-Plated diamond can greatly extend the service plan life.

Mainly includes a variety a concave mold substrate, A concave mold construction and a concave mold

Common Yuzhuo plastic mold std



The concave mold with a variable cavity composed of a convex plate is composed of a convex mold combined substrate, A convex mold component, A convex mold grouped together card plate, A cavity cutting component and a side cut composite plate. synchronized change of mold convex, Concave mold and reliable forming system. It can process a series of plastic parts of different sizes and shapes.

In order to improve the stage production of plastics, it is essential to add various auxiliary materials to the polymer, just like fillers, Plasticizers, lubricants, Stabilizers, Colorants, and so on, in order to become a plastic with good performance.

1. Synthetic resin is the main portion of plastic, And its content in plastic usually is 40%. key large content, And the type of the resin often determines the type of the plastic, People often remember resin as a synonym for plastic. for example, Mix polyvinyl chloride resin with polyvinyl chloride plastic-type material, Phenolic resin and phenolic recycled plastic. the actual, Resin and plastic are two not the same concepts. Resin is an unprocessed raw polymer, Which isn't used to make plastics, But also as a raw subject material for coatings, Adhesives and fake fibers. In addition to a small part of the resin within the plastic, Most covers, combined with the main component resin, ought to add other substances. 2. Filler filler is also known as filler, It can improve the strength and heat resistance of plastics and keep costs down. as an example, Adding wood powder to phenolic resin can decrease the cost, Making phenolic plastic the most cheaper plastics, And on top of that can significantly improve the mechanical strength. Fillers can be separated into organic fillers and inorganic fillers, the first kind such as wood flour, towels, Paper and individual fabric fibers, rogues such as glass fiber, Diatomaceous the planet, asbestos, Carbon black and so on.

3. Plasticizers Plasticizers can boost plasticity and flexibility of plastics, lesser brittleness, And make plastic materials easy to process. Plasticizers tend to be miscible with resins, no-toxic, odor free, sunlight- and warmth-settled high-Boiling organic elements, very popular are phthalates. as an example, In producing PVC plastics, Soft PVC plastics can be had if more plasticizers are added, And hard PVC plastics can be found if no or less plasticizers are added (quantity 10%).

4. Stabilizer In order to steer clear of the synthetic resin from being decomposed and destroyed by light and heat during processing and use, And grant the service life, Stabilizers should be added to the plastic. very popularly used are stearate and epoxy resin.

5. Colorants Colorants can make plastics have various bright and outstanding colors. regularly used organic dyes and inorganic pigments as colorants.

6. Lubricant The role of the lubricant is to prevent the plastic from being dedicated to the metal mold during molding, And similarly make the plastic surface smooth and beautiful. Commonly used lubricants include stearic acid and its magnesium and calcium salts. plus the above additives, flare retardants, Foaming real estate agents, Antistatic providers, and many more. Can also be put into the plastic.

2 Technology job

balanced growth of

The various tools and products used in our daily production and life add some base of the machine tool and the shell of the machine body to the shell of a screw, Button and various household gear, that are closely related to the mold. The shape of the mold determines the shape of the items, And the processing quality and precision of the mold also determine the quality of the service. as a result of different materials, overall look, demands and uses of various products, The molds are split into non-Plastic molds which can include casting molds, Forging conforms, Die illuminating molds, rubber stamping molds, And plastic-type molds.

lately, With the rapid advancement the plastic industry and the continuous improvement of strength and precision of general and engineering plastics, the appliance range of plastic products is also expanding, regarding: Household home, tools, manufacture equipment, car In many fields such as daily hardware, The ratio of plastic products is rapidly increasing. A properly designed plastic part can often replace multiple more traditional metal parts. The trend of plasticizing industrial providers daily-Use products is maximising.

intending

General meaning of mold: In industrial growth, Various presses and special tools installed on the press are used to make parts or products of desired shapes through metal or non-Metallic items. Such special tools are each called molds.

account of the injection process: The mold is a tool for earning plastic products. It contains several groups of parts, And there is a molding cavity in this mixture. During treatment molding, The mold is clamped on the injections molding machine, The molten plastic is injected back into the molding cavity, And cooled and carved in the cavity, And then the upper and lower molds are separated. for an additional injection, the full injection process is cyclic.

depending on different casting systems, Molds can be divided into three categories:

(1) Large nozzle mold: The runner and gate are on the parting line, And they are demolded with the product when the mold is opened. the look is simple, Easy to practice, And the expense of is low, so many people use the large nozzle system for operation.

(2) Fine mist nozzle mold: Runner and gate are not on the separating line, Generally directly on the product, So it will be important to design an additional set of nozzle parting line, The design is more technical, The processing is more troublesome, And it is generally selected in accordance with the product requirements Fine nozzle system.

(3) Hot runner mold: The structure of this sort of mold is roughly the same as that of the fine nozzle. The change is that the runner is in one or more hot runner plates and hot mouths with constant temperature. you cannot find any cold material demolding, Runner and pouring The outlet is directly on the information, So the runner does not need to be demolded. this method is also called a waterless system, Which can save raw materials. It is suitable for the problem where the raw materials are expensive and the product requirements are high. it is not easy to design and process, And the mold fees are high.

the hot runner system, generally known as the hot runner system, Is mainly including a hot gate sleeve, A hot athlete plate, And a heating-watched electric box. Our common hot runner structure has two forms: Single-state hot gate and multi-point hot gate. Single-Point hot gate is to try using a single hot gate sleeve to directly inject molten plastic into the cavity, It is created for a single cavity single gate plastic mold; multi-ply-Point hot gate is using the hot runner plate to branch the molten material into each Sub-Heating gate sleeve and then go into the cavity, It is towards single cavity multi-Point feeds or multi-cavity mold.

features about hot runner system

(1) No nozzle compound, No piece-Processing is essential, so your entire molding process is fully automated, Saving working time and improving work productivity.

(2) Low duress loss. The temps of the hot runner is equal to the heating of the injection nozzle of the injection molding machine, Which avoids the surface moisture build-up or condensation of the raw material in the runner and the injection pressure loss is small.

(3) The repeated use of nozzle materials will degrade the abilities of plastics, And the use of hot runner system without nozzle materials can reduce the loss of unprocessed trash and thus reduce product costs. the cavity, The environment and pressure are uniform, the tension of the plastic part is small, And the density is uniform. Under a lower injection pressure and a shorter molding time, A better product is injected than the general injection system. For transparent parts, Thin points, Large plastic-type materil parts or high-Demand vinyl parts, It can show its importance, it will produce larger products with smaller models.

(4) The hot nozzle adopts consistent and serialized design, And provides you with various nozzle heads for selection, while having good interchangeability. The uniquely designed and processed electric heating ring can achieve uniform heating temperature and long service life. The hot runner system provides you with hot runner plates, thermostats, and many others, With great design, various types, delightful use, Stable and steady quality.

disadvantages of hot runner system application

(1) The closing height of full mold is increased. Due to adding hot runner plates, The overall height of the mold has grown.

(2) The heat radiation is hard to control. The difficulty of the hot runner is the heat loss of the runner, Which is a major problem to be solved.

(3) There is thermal improvement, And thermal expansion and contraction are issues to be considered in our design.

(4) Increased mold manufacturing costs and higher prices of standard accessories for hot runner systems have affected the popularity of hot runner molds.

3 matters needing affection

1. Don't just focus on product design and ignore plastic mold creating.

When some users are developing products or trial manufacture of new products, They often only focus on product development and development at the initial stage, Ignoring the notifications with the plastic mold making unit. After this product design plan is initially determined, There are two benefits to contacting the mold business in advance:

1. It can make sure you keep the designed product has a good forming process, And the stereotype design will not be modified because the parts are tough process.

2. The mold maker can make design preparations in advance to prevent inadequate consideration in a hurry and affect the building period.

3. to supply high-excellent plastic molds, Only if the supply and demand sides cooperate closely can the cost be reduced and the cycle can be shortened.

Second, Don't just states price, But the actual quality, Cycle and products.

1. There are various kinds of molds, which will be roughly divided into ten categories.

3. Due to the special expectations for forming some parts, The mold also requires advanced types of procedures such as hot runners, gas-made it easier molding, and nitrogen cylinders.

4. producer should have CNC, EDM, WEDM and CNC copy milling machine, extremely high-precision grinding machine, maximum-precision three-Coordinate measuring the windshield wonder, Computer design and related a software program.

5. usually, good-Scale stamping dies (Such as car and truck cover parts dies) must evaluate whether the machine tool has a blank holder mechanism, Or even edge lube, multi-Station accelerating, and so on. along with stamping tonnage, It is also in order to consider punching times, feeding devices, Machine tools and mold shielding devices.

6. The manufacturers methods and processes of the above-Mentioned molds are not possessed and mastered by every opportunity. when deciding a cooperative manufacturer, You must realize its processing capabilities, Not only towards the hardware equipment, But also combining leadership level, producing experience and technical strength.

7. for the similar set of molds, Quotes from different companies sometimes vary greatly. you ought not pay more than the value of the mold, But it shouldn't be less than the cost of the mold. Mould vendors, as you, Must make equitable profits in their business. Ordering a set of molds with much lower quotations can be a troublesome start. Users must proceed from their own requirements and make a complete measurement.

3. Avoid variable-Head cooperation and try to make one-Stop plastic mold making and product accepting.

1. With prescreened molds (ideal test pieces), Batches of qualified products may definitely not be produced. This is mainly related to the selection of machine tools for the parts, The forming project (Forming temp, getting together time, and thus.) And the technical expertise of the operator.

2. with an above average mold, There is yet another good forming process, the one-Stop cooperation, try to avoid multi-Head venture. If the conditions are not met, It is necessary to choose one party to be fully responsible and make sure to write clearly when signing the contract.

3. 马氏体时效合金钢

这种刚才具有足够的力学性能和突出的工艺性能，特别是有较高的强度、韧度、耐磨性、低的热膨胀系数，是制造注塑模的好钢材，但是价格贵。

4. 硬质合金

主要用于制作寿命要求很高，制件生产批量大的模具。

4合理选择

随着塑料制品在工业及日常生活中的应用越来越广泛,塑料模具工业对模具钢的需求也越来越大。在塑料成型加工中,模具的质量对产品质量的保证作用是不言而喻的。塑料模具已向精密化、大型化和多腔化的方向发展,对塑料模具钢的性能的要求越来越高,塑模钢的性能应根据塑料种类、制品用途、生产批量、尺寸精度和表面质量的要求而定。

影响塑料磨具钢选择的因素

塑料模具的零部件分为两大类:一类为结构件,包括浇注系统、导向件、顶模板、顶出机构、支承件等;另一类为成型件:包括型腔、型芯、嵌镶件等。其中类零件可按机械零件的要求进行强度和结构设计,材料一般选用中低碳素结构钢、合金钢和碳工钢。而成型件由于结构复杂,要求工件的尺寸精度高,表面粗糙度值低,接缝密合性好,对模具材料的力学性能、耐磨性及加工工艺都提出了专业要求。

1.1 模具的主要失效形式

由于模具的工作温度较高,压力较大,有的塑料材料易于与模具表面发生磨损和腐蚀作用,有时还会受到脱模带来的和碰撞。其主要失效形式有以下三种。

1.1.1 表面磨损

由于塑料中增强树脂填料,对模具型腔表面产生冲刷、磨损和腐蚀作用,从而影响到模具型腔表面粗糙度值升高,尺寸超差。

1.1.2 变形

模具局部产生塑性变形,导致表面发生凹陷、皱纹、麻点和棱角堆塌等损坏。

1.1.3 断裂

由模具局部应力集中导致的断裂现象。

1.2 模具的制造和使用要求

塑料模具对材料在强度和韧度上的要求低于冷作模和热作模,根据其失效形式和工作要求,其基本性能要求归纳为:

1.2.1 足够的耐磨性

由于表面磨损是模具的主要失效形式之一,因此模具应当有足够的硬度,以保证模具的耐磨性,保证模具的寿命。通常需要选择合适的材料和恰当的热处理方法来满足硬度的要求。但当硬度达到一定值时,硬度对耐磨性的提高作用就不明显。

1.2.2 减少热处理变形影响

由于注塑零件形状往往比较复杂,塑料模具在淬硬后很难加工,有时甚至无法加工。为了提高硬度,必须进行热处理。要采取适当的措施来减低热处理变形的影响,对于必须在热处理后进行加工的模具,应选用热处理变形小的材料。

1.2.3 优良的切削加工性能

塑料模具的制造中切削加工成本常占大部分,为了延长切削刀具的使用寿命,保证加工表面质量,要求模具材料具有良好的切削加工性,对于预硬性材料,要求淬火后也有好的加工性。

1.2.4 良好的抛光性能和刻蚀性

为获得高品质的塑料制品,模具内型腔的表面必须进行抛光以减小表面粗糙度值,为了保证模具具有良好的电加工性和镜面抛光性,花纹图案刻蚀性,模具钢应当是材料的纯洁度高,组织细微、均匀、致密,无纤维方向性。

1.2.5 良好的耐腐蚀性能

注塑PVC或加有阻燃剂等添加剂的塑料制品时,会分解出具有腐蚀性的气体,对模具的表面有一定的化学腐蚀作用,制作这类模具时,应选用具有一定抗腐蚀能力的钢材。

常用模具钢的类别及特性

2.1 渗碳钢

渗碳钢由于退火后的硬度低、塑性好,可以采用冷挤压法成型,从而提高工效,减低成本。挤压复杂型腔时,退火后的硬度小于100HBS;挤浅型腔时,小于160HBS,挤压成型后,经渗碳、淬火和回火处理,表面硬度为5362 HRC。达到表面耐磨性高,心部韧性好的要求。08Cr4NiMoV（LJ）是国内开发的冷挤压成型专用钢,具有成型性能优良、渗碳层深、热处理变形小、耐磨性好等优点。其淬火处理的佳温度是850,回火温度可视模具工作条件选择。

2.2 调质型模具钢

工艺要求是在完成模具机械加工后,再进行调质处理,使模具达到较好的综合机械性能。一类是45、55等碳素钢,适宜于形状简单或精度要求不高、使用寿命不长的模具。可以选用SM45、SM55等塑料模具专用钢（YB/T094—1997、YB/T107—1997、YB/T129—1997）,此钢材的纯净度好,力学性能稳定。另一类是合金钢,可以在调质后进行碳氮共渗,进一步提高耐磨性和抗蚀性。其中:40 CrMo有良好的低温韧度和低的缺口敏感性,适于制作中型模具。42 CrMo属于高强度钢,且有较高的疲劳极限,低温韧性好,适于制造要求一定强度和韧性的大、中型塑料模具。38 CrMoA1是典型的渗碳钢,调质后渗氮处理,表面硬度高（大于850HV）并具有一定的抗蚀性。适用于PVC,PC的塑料模具。此外5 CrNiMo、5 CrMnMo等热作模具钢,在塑料模具中主要用于使用温度较高,耐磨性要求高的模具,如热固性塑料模。

2.3 预硬性塑料模具专用钢

可以直接使用已经预硬处理的模块、扁（下转第192页）（上接第91页）钢进行加工,避免了加工后再热处理所造成的各种缺陷,从而提高了模具的制作精度,同时缩短了制作周期。塑料模具钢的主流品种,可以划分为一般型和易切削型以及非调质型等几类。

模具钢的选用及热处理

塑料模具的制作成本中,加工和抛光占到了70%80%,因此在选用模具材料时,应在保证模具使用性能要求的同时,尽可能地提高其加工工艺性能。其选用方法可按以下方式进行。

（1）根据塑料制品的种类和质量要求选用。

（2）根据塑料件的生产批量选用。在其它影响因素确定时,生产批量越小,对模具的耐磨性和使用寿命要求越低。因此,可选用性能指标低的材料。小批量时,可以选用调质型合结钢或碳结钢。中等批量（30100万件）时,可以选用P20,5NiSCa,SM2等,大批量时,5NiSCa,PMS等。

（3）根据塑料件的尺寸大小及精度要求选用。对大型高精度的注射模,当塑料件生产批量大时,采用预硬化钢,以防止热处理变形。

（4）根据塑料件的复杂程度选用。应充分考虑模具的加工工艺性,尽量选用易切削,热处理变形小,耐磨性好的材料。

5发展

近几年，随着中国模具工业的迅猛发展，为国产模具钢提供了一个巨大的市场，带动了国内模具钢的产量、品种、规格及品质水准的提高。我国冶金行业研制开发和引进了大量模具行业所需的钢种，但国产模具钢无论在品种还是质量上仍难以全部满足国内模具市场的需求。

以冷作模具钢为例，目前我国只有Cr12、Cr12MoV、CrWMn钢。我国的Cr12MoV钢中，钼和钒的含量较低，比D2钢综合性能差。CrWMn含碳量较高，且不含钒，容易产生严重的网状碳化物，影响使用性能。如今国外根据冷冲压件向高精度、标准化发展的趋势，早已开发了高性能模具钢，其中有二次硬化钢OCM、DC53、Vasco、Die；火焰淬火钢SX10570L；空淬微变形钢A4等。这些新型模具钢我国也急需研制开发。

国产热作模具钢同样存在差距，目前我国通用型钢种中只有2个钢号。而国外除了通用型钢种外，还新发展了YHD3、H26等品种。塑料模具钢的差距则更大。就品种而言，标准仅1个钢号，而美国有7个钢号，且形成了较完整的用钢系列。2012年国内模具钢消费量至少150万吨，其中，市场是巨大的，但国内模具钢制造企业要想在其中占据更大的份额，就必须在科研开发、技术改造、市场开拓上下更大的功夫。

塑料挤出模具的历史

利用螺杆泵送液体的思想可以追溯到古希腊的伟大科学家阿基米德，他将其应用与城市的防御体系中。据记载，早的工业挤出机是由Joseph Bramah 于1975年发明的。他由一个手动的柱塞和机头组件所构成，用于连续生产铅管。历史上，个阿基米德螺杆挤出机的由英国人 Matthew Gray 和美国人 donald Royle 获得。从19世纪中叶到现在，挤出加工曾用于古塔波胶、橡胶、硝酸纤维素和酪蛋白的加工。大约在1925年，人们挤出了各种聚氯乙烯，这成为现代挤塑加工技术开始的标志。



塑料挤出模具的发展

我国的聚合物挤出工业近几十年得到迅猛发展，尤其是改革开放以来，聚合物加工机械及模具工业取得了举世瞩目的成就，其年平均增长速度高于国民经济总的增长速度，达到两位数以上。1996年以来我国聚合物制品的产量一直位居世界第二。2000年The output of polymer supplements in China reached 21 million tons, And the output value of the polymer handing out machinery industry was 8.529 million yuan.

concerning basic theory, Chinese scholars have made great input. Professor Zhu Fuhua of Beijing school of Chemical Technology and Professor Peng Yucheng of South China university of Technology led two research groups and began to study extrusion in 1978. After beyond 20 years of hard work, A series of achievements have been made in the creation technology of polymer processing, Extrusion theory and component, Which has made its own contribution to the introduction of extrusion processing technology.

With the development of computer systems, the employment of CAE technology in the extrusion process has also been booming. Many softwares have seemed to simulate the screw extrusion process, for instance EXTRUD, POLYFLOW, FLOW2000, consequently on. notwithstanding, you can still find some problems with these software. you might find, There is a big gap between the simulation results and the trial and error results, And further theoretical research support is required to improve them.

2 General design points of fake extrusion die

Extrusion die is the core part of extrusion manufacture. The technical status of extrusion die directly relates to the soundness of extrusion production, the products extruded products, The efficiency of extrusion secretion and the service life of the die itself. thence, The design of the extrusion mold is vital. when designing the machine head, these types of points should be noted:



The head cavity should be structured

In order to enable the pad to be evenly extruded along the flow path of the machine head, To avoid overheating decomposition of the pad due to stagnation, there has to be no sharp shrinkage in the head, And there should be no dead ends and stagnation areas. place roughness Ra value is 0.4m



Sufficient compression setting ratio

depending on the difference of plastic products and plastic varieties, Design a machine head that can produce a sufficient compression ratio to eliminate the joint seam caused by the shunt bracket and make the product dense.



excellent cross-Sectional look

Due to the plastic effectiveness, difficulty, thickness, Shrinkage rate and other elements, The die frustrated-Sectional shape of the die is distinct from the actual cross-Sectional shape of the device. This factor should be considered during design to make the die die have a reasonable cross-Sectional the original shape.



Compact rhythm and disassembly

Under the fitness of satisfying the mechanical performance, it is very important to design a head with rhythmic advancement, Tight association, Uniform heat pass on, opportune disassembly and assembly, And no seapage.



equitable selection

your machine head should be made of steel with corrosion resistance, Friction resistance, Good tensile intensity and high hardness. Some are also chrome plated while using situation.





Blow creating

1 blow creating

Blow molding originated in the 1830s. It wasn't until 1979 that blow molding entered the stage of wide instrument. during this period, spend-Molded parts include: Polyolefins, anatomist plastics and elastomers; the usage of blow-Molded products involves cars or trucks, office equipment, Household machines, medical treatment, and the like, these can also produce 60,000 bottles hourly. high blow moldings (Piece importance up to 180kg), Multilayer blow molding equipment has been greatly developed;

The blow molding equipment systems has adopted a closed-Loop operation system of microcomputers and solid-State electronics captive market, And the evolution CAE / CAM technology has become increasingly mature; And the blow molding machinery is more professional and unique.





2 molding method

Different blow molding methods have different advantages in processing different products due to variations in raw materials, Processing considerations, end product and cost. The detailed blow molding process can refer to the novels.

Here we introduce the quality of blow molding from a macro perspective. Blow molding of hollow items includes three main methods: Extrusion blow molding: Mainly used for processing of unsupported parisons; procedure blow molding: Mainly used for processing of parisons sustained by metal cores; warm your muscles blow molding: putting Extrusion-greatly-Blow molding and procedure-extend you too far-Blow molding can process biaxially oriented gadgets, Greatly reducing production costs and improving product play. and, there are certainly multi-Layer blow molding, data compresion blow molding, Dip coating blow molding, Foam blow molding, three-sizing blow molding, and also so on. but nevertheless, 75% of blow molded bags are formed by extrusion blow molding, 24% by injections blow molding, And 1% by other blow molding. Among all blow molded appliances, 75% are biaxially expanded products. mastering french in france extrusion blow molding are high production efficiency, Low fitness gear cost, And a number of molds and machinery. the disadvantages are high scrap rate, Poor recovery and utilization of waste, Thickness charge of products, And dispersion of unprocessed trash. After the trimming operation must be undertaken. The advantage of injection blow molding is that there is no waste generated along the way, Which can well control the wall thickness of the product and the dispersion of the fabric. The tiny-Neck product has high molding excellence, The surface of the product is smooth, And it can be economically produced in small batches. The disadvantage is the very high cost the molding equipment, And it is only suitable for small blown products to some extent.

the method conditions of hollow blow molding require that the compressed air of the parison in the blow mold must be clean. injections blow molding air pressure is 0.55 1MPa; Extrusion blow molding strain is 0.2l 0.62MPa, And stretch blow molding pressure often does need to be as high as 4MPa. In the solidification of materials, Low pressure makes the inner stress of the product low, the strain dispersion is more uniform, And the low stress can improve tensile, energy, And bending properties of the finished products.

Hollow blow molding is split up into injection blow molding

, Extrusion blow molding and stretch your muscles blow molding. Injection blow molding is to use injection molding resolution to first make plastic into a bottomed parison, immediately after which it move the parison into a blow mold for blow molding. In the extrusion blow molding act, The tube blank is straightly extruded by the extruder and hanged in a pre-Divided cavity installed directly inside the head; When the sagged parison reaches the chosen length, The mold is closed swiftly and close The incision of the mold cuts the tube blank; Compressed air is introduced from the small hole in the parting surface of the mold, so your parison is inflated and molded against the mold wall; pressure is maintained, And this system is opened after the device is cooled and shaped in the cavity.



There are many types of thermoplastics used for hollow blow molding. The commonly used raw materials are polyethylene, Polypropylene, Polyvinyl chloride and polycarbonate polyester. They are very popularly used to form packaging containers for various liquids, Such as other bottles, barrels, containers, therefore on.. The way to distinguish between extrusion blow molding and injection blow molding (Including injection stretch blow molding) Is to observe the bottom of the product. the actual has a belly button-Like procedure point for procedure blow molding or injections stretch blow molding. underneath has a mold clamping line for extrusion Blow molded products.

4 service types

Two types of business parts. The packing containers include: Packaging cardboard boxes, grand-Volume memory barrels / tanks, And collapsible containers. bear in mind, With the maturation of the blow molding process, los angeles cpa and more blow molded products of industrial parts, And the range of applications is becoming more and more extensive. at this moment, Containers account for about 80% of the share of the market, raising the by about 4% per year; While industrial and structural products be aware of 20% of the total, With an annual rate of growth of 12%. The increase in container consumption is due to the continuous expansion of the required forms range of twistable plastic containers. The increase in the consumption of industrial products is mainly due to the improvement of new processing technologies, for instance multilayer parison extrusion, Biaxial extrusion, And non-Axial shaped blow molding, for example. Table 2 lists the applications and gratification requirements of some blow molded products.

5 move forward

in the molding process, The raw material polymer is first encountered with high shear forces when passing through the die, And then the information presented exhibits extrusion expansion and shrinkage. When the sagging parison is made, Its expansion rate is close to zero. Then the parison is inflated and pressed the particular mold, presently showing a low expansion rate. Excessive die expansion will produce waste materials. Excessive shrinkage leads to uneven wall thickness completely of the part, Even severely can not form. that is why, when choosing a polymer suitable for blow molding, The viscoelastic properties of shear and expansion must be clear. HDPE is widely used in blow molding due to good thermal stability and various modified products. Through copolymerization and joining together, Research on recycleables for blow molding has also made some progress in continuous extrusion blow molding grade resins, as an example PA6, PP, as PET. Intermittent parison blow molding is in theory suitable for secondary processing of structural plates and large parts, Requiring the use of anatomist plastics, Such as flame retardant ABS, strengthened PVC, fine-tuned PPO and PC. The hot temperature resistance of plastics is generally poor, And only a few resins can be blow molded on conservative equipment to form large parts. In the blow creating of polyethylene naphthalate (pad) / PET integrates, it is crucial to form a composite layer of resins such as (Ethylene / convertible top acetate) Copolymers and HDPE and PET that prevent oxygen puncture and waterproof gas puncture, And create an anchor layer to improve the permeability and thermal stability of the PEN / PET material. right now, It is being studied to use HDPE and PA6 by multilayer blow molding to form fuel tanks.

Blow molding devices has been greatly improved. The newer results are:

Using improved infrared heating energy solutions for re-Blow molding;

Very high speed rotational extrusion pressure, Mainly used in the production of milk bottles;

The mold is coupled to the shuttle press to compensate the jet flow phenomenon;

multi-Layer continuous extrusion blow molding impermeable container;

Through strict domination over oriented crystallization and thermal crystallization, Preform and mold their environment, Blowing hassle, And house time of parison in the mold cavity, regular heat-Set PET bottles are intended.

from the market's demand for complex and tortuous conveying pipe parts, the creation of off-Axis extrusion blow molding technological innovations has been promoted. This technology is generally known 3D or 3D blow molding.

theoretically, This process really is easy. after the parison is extruded, It is partially inflated and mounted on one side of the die, And then the extruder head or die rotates depending on programmed 2-Axis or possibly a 3-Axis ebook. The difficulty is that large blow molding machines with very large amounts of inertia are necessary to have an error of less than 10% during high-accelerate mold clamping. The adjustable-Layer blow molding process is often used to process impenetrable containers. The improved process is to add a valve system. In the constant extrusion process, The plastic raw materials can be replaced, So that hard and soft products can be produced alternately. When producing large parts such as fuel tanks or automotive exterior structural plates, The pressure in the mold cavity should also be reduced during the cooling process to adjust the processing cycle. The solution is to store the molten material in the melting tank at the front end end of the extruding screw, And then extrude the parison at a rather high speed to minimize the change in the parison wall thickness, Thereby ensuring many people of sag and extrusion expansion.

The storage cylinder head is improved so may possibly extrude heat-subtle plastics such as ABS — R, modernized PPD and PVC. in addition, The redesigned handpiece can be quickly assembled and taken apart during production to facilitate the cleaning of plastics. meanwhile, Streamlined flow channels can be designed for the analysis of plastic rheological qualities and computer flow channel analysis to facilitate the formation of heat-fragile plastics.

6 software control

Has decades of expertise.

The main problems are how thin the parison can be thinned (like the neck area), How thick the thickened parison end up being used drawn (such as the container body or corners), And designing a part with a varying wall density, for instance a concave Edges and shoulders. The focus of its work should be on the viscoelastic belongings of the plastic used. The prediction of the wall thickness of the test tube-Shaped preform is the basis for selecting the wall thickness of the parison with an anti-Permeation effect. This is determined by the degree of crystallization of the preform, The hotness-type stress-Strain elastic premises of the plastic used, And the degree and everyday use of freezing stress formed by injection molding. living in 1980, GE established for thermoforming and blow molding:

The control software for parison blow molding must consider the next factors: Uneven parison wall thick; Parison cutouts and orbital blow molding pipe cutouts; before-control of the parison before closing the mold; Opening location and structure Cutting position of parison edge in blow molding. recently, The mercantile blow molding simulation software mainly includes C-PITA of the first sort American ACTech Company and POLYFLOw of Belgium. the actual of numerical simulation lies in: Large traces, Nonlinear element behavior, Contact hassles, And some physical instabilities in the expansion process, And these difficulties will lead to a series of nonlinear equations that need to be solved iteratively. included in this, The study of materials and blow molding mechanism happens to be the difficulty and hot spot of research. as an example, Stretch blow molding is widely used, But the statistical description of stress-Induced crystallization required for the simulation of this procedure has not been suitable so far. path. The extrusion blow molded parison is formed when the polymer melt flows from the annular die. The geometry of the annular pipe and the viscoelastic properties of the material will directly impact on the expansion of the parison. Existing viscoelastic education cannot be described. this procedure.

当今高强钢、超高强钢很好的实现了车辆的轻量化，提高了车辆的碰撞强度和安全性能，因此成为车用钢材的重要发展方向。但随着板料强度的提高，传统的冷冲压工艺在成型过程中容易产生破裂现象，无法满足高强度钢板的加工工艺要求。在无法满足成型条件的情况下，国际上逐渐研究超高强度钢板的热冲压成形技术。该技术是综合了成形、传热以及组织相变的一种新工艺，主要是利用高温奥氏体状态下，板料的塑性增加，屈服强度降低的特点，通过模具进行成形的工艺。但是热成型需要对工艺条件、金属相变、CAE分析技术进行深入研究，该技术被国外厂商垄断，国内发展缓慢。

过去在生产深冲或者重冲工件，大家都认为耐压型（EP）润滑油是保护模具的好选择。硫和氯EP添加剂被混合到纯油中来提高模具寿命已经有很长的历史了。但是随着新金属高强度钢的出现，环保要求的严格，EP油基润滑油的价值已经减少，甚至失去市场。

在高温下高强度钢的成型，EP油基润滑油失去了它的性能，无法在极温应用中提供物理的模具保护隔膜。而极温型的IRMCO高固体聚合物润滑剂则可以提供必要的保护。随着金属在冲压模具中变形，温度不断升高，EP油基润滑油都会变薄，有些情况下会达到闪点或者烧着（冒烟）。IRMCO高分子聚合物润滑剂一般开始喷上去时稠度低得多。随着成形过程中温度的上升，会变得更稠更坚韧。实际上高分子聚合物极温润滑剂都有“热寻性”而且会粘到金属上，形成一个可以降低摩擦的隔膜。这个保护屏障可以允许工件延展，在高要求的工件成型时没有破裂和粘接，以此来控制摩擦和金属流动。有效的保护了模具，延长了模具使用寿命，提高了冲压的强度。

5成形技术

冲压模具的快速成形技术

数字化编码钣

随着经济的快速发展和市场需求的多样化,人们对产品生产周期的

要求越来越短,尤其在小批量甚至单件生产方面,要求现代制造技术不仅要有较高的柔性,还要有更新的、更能满足市场要求迅速变化的生产模式。数控单元冲压模具快速成形技术,就是为适应此种状态而产生的。

钣件的形状可分割成一些简单的图形元素,然后合成所需图形。例如:矩形是4个直角的合成;波浪形是一些曲线的合成等。因此,对于一些精度要求较高的小批量甚至单件生产的钣金件,可以用一些通用件迅速组装成单元冲压模具,采用数控技术,使之快速成形。将被加工钣金件看成一个可被分割的平面图形,对分割出来的简单图形元素进行数字化处理。即按其方位进行定位编码。如图1所示的非等距简单图形零件的数字化,缺口1、2、3、4的（x,y）均相等,方孔5的（x,Y）均等于2倍的（x,y）,设现有通用冲头的宽等于x,长等于y,则按如图1所示进行编号。缺口1由位置（2,0）以及位置（3,0）合成,缺口2、3、4同样由两个位置合成,方孔由8个位置合成。如果采用矩形单元快速成形,可以获得如图2所示的二维编码,由于划分过细使得到的编码较长。如果采用正方形单元快速成形,则可以获得如图3所示的二维编码,其编码减小一半。

矩形单元二维编码如下：



形零件如钥匙齿形的快速成形由于齿距相等河以进一步简化编码。钥匙齿形编码示意图，如图2所示。图中采用三角形单元，实际应用采用的是梯形单元编码可以降为一维数组。

参数定义:

齿数冲压的次数，现假使为5。

齿距冲压时，Y方向的每次移动的距离。

级差值—冲压时X方向移动一个单位



时的距离。

级差数冲压时，X方向的移动单位。

当选定齿距和级差值后，钥匙的齿形加工位置可以转换为级差数后齿形编码为一维数组（（2 1 3 2 1）。由以上可知数字化编码是单元冲模快速成形的关键，合适的编码不仅可以提高生产效率，而且可以节省存储内存。

结构设计

大部分中小型企业尚不具备购买数控冲床的经济实力，数控单元冲压模具可以直接安装在普通冲床上作为简易数控冲床来使用。

快速成形模具机构示意图如图3所示。上模为凸模机构。光电头安装在上模板下方以检测凸模的起落。坯料的装夹要根据不同的需要进行设计。料板由步进电机控制丝杠分X,Y方向驱动。下模为凹模机构，直接安装在工作台上。

驱动器的型号、种类较多，细分型为考虑对象。因为细分型可消除电机的低频振荡，可提高电机的输出转矩及分辨率。顾及速度和精度细分系数定为4。

4.2 系统硬件设计

数控单元冲模是安装在曲轴式压力机上的，机床的冲压原理不变。需要控制的是两方面内容:首先要确定零点以及各工位点的位置;其次在上冲模往复动作的启停间被加工件的按编码所得的X,Y方向的快速进给送料运动以及这两个动作的协调。即实现冲压和送料动作的同步控制。控制系统框图，如图4所示。光电信号检测电路图，如图5所示。



数控系统的人机界面采用键盘输入LED显示键盘具有数字键、设定、修改、查寻、X及Y方向的调整、执行等的功能键，可用来完成加工程序的输入、修改及对控制的操作和调整等。操作人员根据被加工件的形状在计算机上进行编码，自动生成加工程序，通过串行口将加工程序下载给单片机并且保存在FLASH ROM中。工模安装后手动调整零位。进入执行后单片机从FLASH ROM中取得加工程序，并计算X,Y方向的步进距离后再将其转换成相应的步进脉冲数控制X,Y方向的步进电机的转动步数。当光电信号检测到上模位于开启位置时数控系统迅速将待加工件定位到加工位置，并且启动冲床上冲模下压，实现一次冲压。在冲床带动上冲模开启时数控系统迅速地将待加工件移动到下一加工位置等待下次冲压，直到完成加工停止冲床运动。



4.3 系统软件设计

整个系统由上位机来管理。系统软件语言采用Visual significant 6.0编制其集成开发环境（IDE）集设计、修改、调试、生成等功能于一体，人机交互界面十分友好。它是功能强大的Windows环境下的编程语言简单易学可视化程度高。

系统软件结构采用模块化结构，共有5个功能模块:系统开机后进入Windows界面双击“数控单元冲模”图标，即弹出应用界面，可选择功能模块。系统软件功能模块图如图6所示。



编辑模块用来完成用户对所设定的参数组进行操作的程序的编辑、修改、生成。

参数设定模块将输入的参数组制成数据表，送入数据库以备程序的调用。

运行管理模块负责程序的运行、中断。

通信模块负责上、下位机之间的通信管理，就是将控制程序段及调用的参数组使用MSCOMM控件，通过RS232串行口送入单片机使单片机执行控制工作。

查询模块。方便用户对已存文件的查看与调用。

单片机的程序也采用模块化结构，与上位机一样共有5个功能模



块通过通信接口接受上位机的输入指令，控制X,Y方向步进电机的运动。也可以脱离上位机直接控制运行。上位机通信程序流程图，如图7所示。下位机通信程序流程图，如图8所示。

随着数控技术、伺服技术、运动元件的发展，以及市场经济的需要，数控单元冲压模具快速成形技术得到迅速发展。对于中小型传统企业，这种结合传统制造工艺的高新技术无疑是一种投资省，见效J陕，方便、快捷的技术。随着经济和科学技术的不断发展，实现自动上下料装备、外置模具库自动换模装备等，已经摆在人们的面前。可见，数控冲压的发展是以相关技术和新结构的研制为基础的。单元冲压模具快速成形技术，无疑是先进冲压技术发展的一个新起点。

6模内攻牙

模内攻牙又称模内攻丝,是一种替代了传统人工攻牙的新技术,目前传统的攻牙设备已经不能适应冲压产品需求,效率太低,加工时间长.远远满足不了市场的需要.模内攻牙技术的导入使得冲压模具真正的实现了自动化,效率化,攻牙范围可达到小M0.6,大可达到M45.精度可达到0.01mm,模内攻牙技术使的冲出来的产品不需要再进行第二次人工攻牙,其挤压出来的产品质量有保证,表面光洁度好,效率高,成本低.广泛应用于冲压

7冲压模具材料

creation

制造冲压模具的材料有钢材、硬质合金、钢结硬质合金、锌基合金、低熔点合金、铝青铜、高分子材料等等。制造冲压模具的材料绝大部分以钢材为主，常用的模具工作部件材料的种类有：碳素工具钢、低合金工具钢、高碳高铬或中铬工具钢、中碳合金钢、高速钢、基体钢以及硬质合金、钢结硬质合金等等。

基本分类

a.碳素工具钢

在模具中应用较多的碳素工具钢为T8A、T10A等，优点为加工性能好，价格便宜。但淬透性和红硬性差，热处理变形大，承载能力较低。

d.低合金工具钢

低合金工具钢是在碳素工具钢的基础上加入了适量的合金元素。与碳素工具钢相比，减少了淬火变形和开裂倾向，提高了钢的淬透性，耐磨性亦较好。用于制造模具的低合金钢有 CrWMn、9Mn2V、7CrSiMnMoV（代号CH1）、6CrNiSiMnMoV（代号GD）等。

m. 高碳高铬工具钢

常用的高碳高铬工具钢有Cr12和Cr12MoV、Cr12Mo1V1（代号D2）、SKD11，它们具有较好的淬透性、淬硬性和耐磨性，热处理变形很小，为高耐磨微变形模具钢，承载能力仅次于高速钢。但碳化物偏析严重，必须进行反复镦拔（轴向镦、径向拔）改锻，以降低碳化物的不均匀性，提高使用性能。

h. 高碳中铬工具钢

用于模具的高碳中铬工具钢有Cr4W2MoV、Cr6WV 、Cr5MoV等，它们的含铬量较低，共晶碳化物少，碳化物分布均匀，热处理变形小，具有良好的淬透性和尺寸稳定性。与碳化物偏析相对较严重的高碳高铬钢相比，性能有所改善。

u. 高速钢

高速钢具有模具钢中高的的硬度、耐磨性和抗压强度，承载能力很高。模具中常用的有W18Cr4V（代号841）和含钨量较少的W6Mo5 Cr4V2（代号6542，美国牌号为M2）以及为提高韧性开发的降碳降钒 高速钢 6W6Mo5 Cr4V（代号6W6或称低碳M2）。高速钢也需要改锻 ，以改善其碳化物分布 。

m. 基体钢

在高速钢的基本成分上添加少量的其它元素，适当增减含碳量，以改善钢的性能。这样的钢种统称基体钢。它们不仅有高速钢的特点，具有一定的耐磨性和硬度，而且抗疲劳强度和韧性均优于高速钢，为高强韧性冷作模具钢，材料成本却比高速钢低。模具中常用的基体钢有 6Cr4W3Mo2VNb（代号65Nb）、7Cr7Mo2V2Si（代号LD）、5Cr4Mo3SiMnVAL（代号012AL）等。

you have g. 硬质合金和钢结硬质合金

硬质合金的硬度和耐磨性高于其它任何种类的模具钢，但抗弯强度和韧性差。用作模具的硬质合金是钨钴类，对冲击性小而耐磨性要求高的模具，可选用含钴量较低的硬质合金。对冲击性大的模具，可选用含钴量较高的硬质合金。

钢结硬质合金是以铁粉加入少量的合金元素粉末（如铬、 钼 、钨、钒等）做粘合剂，以碳化 钛或碳化钨为硬质相 ，用粉末冶金方法烧结而成。钢结硬质合金的基体是钢，克服了硬质合金韧性较差、加工困难的缺点，可以切削、焊接、锻造和热处理。 钢结硬质合金含有大量的碳化物，虽然硬度和耐磨性低于硬质合金，但仍高于其它钢种，经淬火、回火后硬度可达 68 73HRC。

l.新材料

冲压模具使用的材料属于冷作模具钢，是应用量大、使用面广、种类多的模具钢。主要性能要求为强度、韧性、耐磨性。冷作模具钢的发展趋势是在高合金钢D2（相当于我国Cr12MoV）性能基础上，分为两大分支：一种是降低含碳量和合金元素量，提高钢中碳化物分布均匀度，突出提高模具的韧性。如美国钒合金钢公司的8CrMo2V2Si、日本大同特殊钢公司的DC53（Cr8Mo2SiV）等。另一种是以提高耐磨性为主要目的，以适应高速、自动化、大批量生产而开发的粉末高速钢。如德国的320CrVMo13，等。

选用原则

在冲压模具中，使用了各种金属材料和非金属材料，主要有碳钢、合金钢、铸铁、铸钢、硬质合金、低熔点合金、锌基合金、铝青铜、合成树脂、聚氨脂橡胶、塑料、层压桦木板等。

制造模具的材料，要求具有高硬度、高强度、高耐磨性、适当的韧性、高淬透性和热处理不变形（或少变形）及淬火时不易开裂等性能。

合理选取模具材料及实施正确的热处理工艺是保证模具寿命的关键。对用途不同的模具，应根据其工作状态、受力条件及被加工材料的性能、生产批量及生产率等因素综合考虑，并对上述要求的各项性能有所侧重，然后作出对钢种及热处理工艺的相应选择。

当冲压件的生产批量很大时，模具的工作零件凸模和凹模的材料应选取质量高、耐磨性好的模具钢。对于模具的其它工艺结构部分和辅助结构部分的零件材料，也要相应地提高。在批量不大时，应适当放宽对材料性能的要求，以降低成本。

当被冲压加工的材料较硬或变形抗力较大时，冲模的凸、凹模应选取耐磨性好、强度高的材料。拉深不锈钢时，可采用铝青铜凹模，因为它具有较好的抗粘着性。而导柱导套则要求耐磨和较好的韧性，故多采用低碳钢表面渗碳淬火。又如，碳素工具钢的主要不足是淬透性差，在冲模零件断面尺寸较大时，淬火后其中心硬度仍然较低，但是，在行程次数很大的压床上工作时，由于它的耐冲击性好反而成为优点。对于固定板、卸料板类零件，不但要有足够的强度，而且要求在工作过程中变形小。另外，还可以采用冷处理和深冷处理、真空处理和表面强化的方法提高模具零件的性能。对于凸、凹模工作条件较差的冷挤压模，应选取有足够硬度、强度、韧性、耐磨性等综合机械性能较好的模具钢，同时应具有一定的红硬性和热疲劳强度等。

应考虑材料的冷热加工性能和工厂现有条件。

注意采用微变形模具钢，以减少机加工费用。

对特殊要求的模具，应开发应用具有专门性能的模具钢

选择模具材料要根据模具零件的使用条件来决定，做到在满足主要条件的前提下，选用价格低廉的材料，降低成本。

8辅助技术

模具CAD/CAM技术

计算机技术、机械设计与制造技术的迅速发展和有机结合，形成了计算机辅助设计与计算机辅助制造（CAD/CAM）这一新型技术。

CAD/CAM是改造传统模具生产方式的关键技术，是一项高科技、益的系统工程，它以计算机软件的形式为用户提供一种有效的辅助工具，使工程技术人员能借助计算机对产品、模具结构、成形工艺、数控加工及成本等进行设计和优化。模具CAD/CAM能显著缩短模具设计及制造周期、降低生产成本、提高产品质量已成为人们的共识。

随着功能强大的专业软件和集成制造设备的出现，以三维造型为基础、基于并行工程（CE）的模具CAD/CAM技术正成为发展方向，它能实现面向制造和装配的设计，实现成形过程的模拟和数控加工过程的仿真，使设计、制造一体化。

快速经济制模技术为了适应工业生产中多品种、小批量生产的需要，加快模具的制造速度，降低模具生产成本，开发和应用快速经济制模技术越来越受到人们的重视。快速经济制模技术主要有低熔点合金制模技术、锌基合金制模技术、环氧树脂制模技术、喷涂成形制模技术、叠层钢板制模技术等。应用快速经济制模技术制造模具，能简化模具制造工艺、缩短制造周期（比普通钢模制造周期缩短70%90%）、降低模具生产成本（比普通钢模制造成本降低60%80%），在工业生产中取得了显著的经济效益。对提高新产品的开发速度，促进生产的发展有着非常重要的作用。

9发展现状

发展现状及技术趋势

改革开放以来，随着国民经济的高速发展，市场对模具的需求量不断增长。模具工业一直以15%左右的增长速度快速发展，模具工业企业的所有制成分也发生了巨大变化，除了国有专业模具厂外，集体、合资、独资和私营也得到了快速发展。浙江宁波和黄岩地区的“模具之乡”；广东一些大集团公司和迅速崛起的乡镇企业，科龙、美的、康佳等集团纷纷建立了自己的模具制造中心；中外合资和外商独资的模具企业现已有几千家。 随着与国际接轨的脚步不断加快，市场竞争的日益加剧，人们已经越来越认识到产品质量、成本和新产品的开发能力的重要性。而模具制造是整个链条中基础的要素之一。许多模具企业加大了用于技术进步的投资力度，将技术进步视为企业发展的重要动力。一些国内模具企业已普

以汽车覆盖件模具为代表的大型冲压模具的制造技术已取得很大进步，东风汽车公司模具厂、一汽模具中心等模具厂家已能生产部分轿车覆盖件模具。此外，许多研究机构和大专院校开展模具技术的研究和开发。经过多年的努力，在模具CAD/CAE/CAM技术方面取得了显著进步；在提高模具质量和缩短模具设计制造周期等方面做出了贡献。

例如，吉林大学汽车覆盖件成型技术所独立研制的汽车覆盖件冲压成型分析KMAS软件，华中理工大学模具技术重点实验室开发的注塑模、汽车覆盖件模具和级进模CAD/CAE/CAM软件，上海交通大学模具CAD工程研究中心开发的冷冲模和精冲研究中心开发的冷冲模和精冲模CAD软件等在国内模具行业拥有不少的用户。

虽然中国模具工业在过去十多年中取得了令人瞩目的发展，但许多方面与工业发达相比仍有较大的差距。例如，精密加工设备在模具加工设备中的比重比较低；CAD/CAE/CAM技术的普及率不高；许多先进的模具技术应用不够广泛等等，致使相当一部分大型、精密、复杂和长寿命模具依赖进口。

未来发展趋势

（4）电火花铣削加工

电火花铣削加工技术也称为电火花创成加工技术，这是一种替代传统的用成型电极加工型腔的新技术，它是有高速旋转的简单的管状电极作三维或二维轮廓加工（像数控铣一样），因此不再需要制造复杂的成型电极，这显然是电火花成形加工领域的重大发展。国外已有使用这种技术的机床在模具加工中应用。预计这一技术将得到发展。

（5）提高模具标准化程度

During this Shanghai online Mold Show, The China Mold Association will also award the fourth batch of greater than 10 companies. at that same moment, 'China's key backbone mold enterprises' will reach about 110.

For a lot of time, the roll-out of China's mold industry has been uneven in terms of geographical distribution. the development of the southeast coastal area is faster than that of the central and western regions, And the creation of the south is faster than that of the north. The areas where mold production is concentrated are in the Pearl River Delta and the Yangtze River Delta. It accounts for over two-Thirds of the nation's output value. in order to Luo Baihui, CEO of mold.Net and Deputy secretary-General of Shenzhen Mould scientific research Society, This pattern is starting profound changes. China's mold market is expanding inward and north from the more developed Pearl River Delta and Yangtze River Delta regions, And has appeared in the industrial layout. Some new mold production areas are centered in Beijing, Tianjin, Hebei, Changsha, Chengdu, Chongqing, Wuhan, then Anhui.

impact on safety

The stamping die is the main process equipment for stamping development, And the stamping parts are completed by the relative movement of the lower and upper dies. Due to the continuous separation between the lower and upper molds during processing, If the operator's fingers in order to enter or stay in the closed area of ​​the mold, It will pose a difficult threat to his personal safety.

Main parts and safety must have

1 doing business parts

you-Female mold is a functional part that directly shapes the blank, it is therefore a key part on the mold. The convex and concave mold is not just precise and complex, It should meet the foregoing requirements:

(1) It require sufficient strength and cannot be broken or destroyed during the stamping process;

(2) the information presented and heat treatment should have appropriate requirements to prevent the hardness from being too high and brittle.

2 placement of parts

The positioning parts are the parts that determine the installing position of the blank, And there are the setting of pins (food), style blocking pins (number plates), suggestions pins, Guide dishes, Fixed side kitchen knives, Side weight devices, for example. when designing positioning parts, It should be considered that the operation is convenient, There should not be over-location, And the career should be easy to observe. It 's better to use forward positioning, Outline setting, And guide pin ranking.

3 demanding, Unloading and discharging portions

troubling parts include blank holders and holding plates. The blank holder can press the blanks under pressure to prevent the blanks from arching and wrinkling under the action of tangential pressure. The function of the pressure plate is to prevent the blank from moving and bouncing. The function of the ejector and the unloading plate is to facilitate the ejection and cleaning of squander. They are maintained by springs, Rubber and air cushion push rods on the kit, And can move throughout. The ejector should be fashioned with sufficient ejection force and limited movement. The unloading plate should minimize the closed area or mill the empty slot in the maintaining position. The exposed discharge plate should be bombarded by protective plates to prevent fingers from reaching people or foreign objects from entering. the perimeters and corners of the exposed surface should be blunt.

4 guide portions

Guide post and guide sleeve are a kind of popular guide parts. Its function is to ensure that the convex and concave molds have a matching gap during the stamping work. motive, The gap between the guide post and the guide sleeve should be small compared to the blanking gap. The guide post is set in the reduced die base, To ensure that when the stroke is towards the end dead center, The upper end surface of the guide post is 5 to 10 mm above the top top of the upper template. The guide post should be arranged from the module and the pressure plate, So that the operator's arm doesn't have to pass over the guide post to feed.

5 using and clamping parts

It includes lower and upper templates, Die manages, Convex and concave die fixing plate designs, jam plates, stoppers, and so forth,accessories, The lower and upper templates are the basic parts of the die; Other differing are installed and fixed on them respectively. The plane size of website, Especially the front and back directions should be compatible with the parts, too large or too small are not conducive to operation.

Some molds (Blanking, punching molds) Need to be provided with a pad under the mold frame for the convenience of delivery. at this time, The backing plate and the template are regarding screws, And the thickness of the two backing plates should be equal. The spacing of the backing plate shall be subject to to be able to deliver the piece, And it shall not be too large to avoid website from breaking.

6 buckling parts

it includes screws, peanuts, spgs, guys, washing machines, and a lot more. most commonly use standard parts. how much of standard parts used for stamping dies is large, And the need for fastening and elastic ejection should be ensured when designing and selecting, To prevent the fasteners from being exposed on top operation position, to treat injury to the hands and hinder the operation.

main points of safety in mold design

The structure should try to ensure the regarding feeding, placing your order, Discharging and taking care of waste. For the payment of small parts, It is strictly forbidden to give the operator's fingers, Wrists or other body parts into the mold area; For the developing of large parts, If the operator must type in the mold by hand, The scope of the mold should be reduced if you can Try to shorten the time that a part of the body stays in the mold, And the range of the dangerous area of ​​the mold should be clear, And the protective measures and devices should be equipped.

The some part on the mold should have sufficient strength and rigidity to prevent damage and deformation during use. The fastening parts need anti-Loose measures to avoid dog injury to the operator.

It is banned to produce scraps or workpiece missiles during processing, Which affects the operator's time and even hurts the operator. moreover, Burrs on the punched parts should be avoided to cut the hands. The operator is not allowed to have excessive movement amplitude during the punching operation to avoid the posture that makes the body lose stability; Excessive and excessive movements during the operation are prohibited. keep your strong noise and vibration during stamping. The mold design should indicate the weight of the mold on the drawing, Which is best for installation and guarantees safety. Lifting and handling measures shall be taken for the canning of parts weighing more than 20 kg to reduce labor intensity. The assembly and disassembly of mold parts should be practical and safe, Avoiding involving pinching and cutting hands; The mold should be easy to take apart and store. briefly, Even subtle problems in the mold might be affected by safety. Only by analyzing the specific problems in each operation can the safety precautions in the mold be proposed.

10 protection methods

(1) The mold is loose-fitting: the sum of movement of the punch or die exceeds the unilateral gap. Adjust the amalgamation gap.

(2) slanting of the die: The straightness of the die or die is not appropriate, Or there is a foreign object regarding the templates, Which prevents the template from being flat. Reassembly or grinding correction.

(3) Deformation of web site: the template is insufficient in hardness or thickness, Or deformed by outside impact. Replace the new layout or correct the disassembly method.

(4) Deformation of the mold base: density of the mold base is not enough or the stress is uneven, along with straightness of the guide post and guide sleeve varies. Grind to mend or refill plastic steel or replace the mold base or equalize the force.

(5) Punch interference: or possibly a size and position of the punch are correct, Whether there is any deviation in the positioning of the lower and upper dies, this will loosen after assembly, the precision of the punch is not correct, And the die is not a fact.

(6) punching shear deflection: The punch is not sufficiently strong, The punches are too close, The lateral force is not fair, And the punching is semi-alter. Strengthen the guide protection effect of peeling the inclined plate or add to the punch, Shorten the miscroscopic punch, improve the overall heel and length, program the guide early, look at the feeding length.

Mold trauma

(1) Hot place burial: The quenching temperature is too high or insufficient, The hot and cold temperature and time of the tempering times are not appropriate, And the time of the quenching way is not sure; The problem only appears after a period of use.

(2) stamping and stacking: The blanks frauds punched when they overlap, Usually because stripping plate is broken.

(3) waste blocking: The blanking hole is not drilled or the size does not match or falls on the bed table and is not cleaned in time. The punch and the low template are damaged more.

(4) The punch is removed: It is not fully fixed or hanging, Or the screw is too thin and the effectiveness is not good, or even punch is broken.

(5) No hole evade: The size or depth of the punch pressure plate escape hole is isn't, And the escape a part of the punch and stripping plate is not usually damaged by the stripping plate.

(6) mysterious matter enters: the information blows out and rebounds, The mold parts fail and fall, The screw protrudes from the mold surface or other objects enter the mold, which might damage the lower mold, The stripping plate or the punch, the particular guide post.

(7) installation error: the positioning and direction of the parts are incorrectly installed and damaged.

(8) new season factor: The spring force is lack of or broken or the contour set is not equal to make the stripping plate tilt, Or the spring is not been thinking about well, then may cause overlapping punching to damage the parts.

(9) Improper rubber stamping: the important height is adjusted too low, The guide line loses oil, the material strip is mistakenly fed or half-filled up with, The peripheral equipment just like the feeding, unwinding, And getting involved in collecting machine is damaged, The air pipe is not placed around or opened, The punch is bizarre, destruction caused.

(10) Improper vehicle repairs: adore the look-Mentioned points occurred due to substitution without change or screws not locked or not restored as they were.

sizing variation

(1) Knife edge scratching: The head is too large or the size becomes larger (Cut layout); Becomes smaller (pounding); The flatness is negative. re also-Grind or ditch the die.

(2) No article: The guide pin or other positioning device has no effect, The feeder is not going to relax or the guide pin diameter is not correct, And the guide cannot be remedied. The placement of block is worn and the feed distance is too long.

(3) The die is quite short: The camber turns out to be larger, The chamfering is deficiency of, And the forming is rudimentary.

(4) not enough hole escape: Crushed or suffering a loss or deformed. Clear escape holes or acceleration escape holes and depth.

(5) Ejection is too few: feasting is not smooth, The line is bent, martial arts is not well removed, The upper die pulls the pad, And the ejection is extended.

(6) unacceptable ejection: Improper ejector pin research, the wrong spring force or excessive ejection. Adjust the spring force or change the position or may be pins; Pin milling is short to fit.

(7) Poor ingredient guide: The entire material guide plate is not enough or the material guide gap is too large, Or the mold and the feeder are skewed or the distance between the mold and the feeder is too long.

(8) clipping deformation: Some bending parts cannot allow the material to overlap, And must be dropped eachtime, and even dish-Shaped strain can be overcome by power pad or shear oblique.

(9) bending deformation: Squeezing material at the top of bend; The near hole is deformed by getting force, And the uneven bending is not good enough.

(10) pounding and shearing deformation: the content is twisted unevenly, The size is increased or the eccentricity is uneven.

(11) shock deformation: the merchandise is blown out with too strong air pressure or gravity and impact deformation.

(12) Squeeze chip squeezing: The squeeze variation of waste floating or fine chips remaining on the die surface or foreign objects.

(13) Improper textile: Material width or plate breadth, incompatible material or material hardness, and additionally produce defects.

(14) Poor layout: Poor executive arrangement and poor gap setting. it is not easy to overcome unless the design is changed.

The main technical indicators and precautions of white masterbatch

The white masterbatch has the points of bright color, good and eye-finding, High color strength training, Good dispersion, High attention, quite whiteness, serious hiding power, Good migration challenge and heat resistor, and so forth,accessories. It is traditionally used in injection molding, Blow creating and wire drawing, throwing, Extrusion, taken Film, Foaming, bed sheets, tubes, putting, hollowed out, eva, Blowing sizes, linens, Household gizmo's, animals, packaging Materials, cables and wires, vinyl Bags, motor vehicle, Building material, Sports and leisure products or services, providing bags, product packaging bottles and other plastic products industry.

The main technical references of white masterbatch

1. Migration a level of resistance (location) [4]

2. wet condition content (per cent) [0.30] 8, Total color modification [1.50]

3. Melting the weather (oC) [125200]

4. Dispersibility of white colored masterbatch: [clear dots, stripes]

5. Lightfastness (level of skill) [58]

6. the look of white masterbatch is granular, With uniform particles and continuous color

7. Heat push back (line) [4]

the theory is that, The company's white masterbatch that meets the above technical indicators is good.

10 aspects to consider when purchasing white masterbatch

1. Whiteness

The whiteness of the white masterbatch is mainly offered by the titanium dioxide in the masterbatch, And you will find factors that affect the whiteness of the titanium dioxide, such as size, Shape and particle size everyday use of titanium dioxide particles, Types and contents of impurities, And the lattice of titanium dioxide dust Defects. normally, Because the chlorination method has higher purity of the raw material titanium dioxide and less impurities in the processing process, The whiteness of the titanium dioxide is preferable to the sulfuric acid method. In true white masterbatch market, Many white masterbatch clothes manufacturers impersonate titanium dioxide by adding equal amounts of calcium carbonate, Barium sulfate, And zinc oxide sulfide. this truth is, The whiteness of these inorganic powders is matchless with titanium dioxide.

2. concealing power

Hiding power is also a critical indicator of white masterbatch. Good hiding power means the pigment has strong coloring power, And the desired effect can be obtained with a small amount of addition. The hiding power of white masterbatch depends on the option of titanium dioxide Compared with the processing technology, Rutile titanium dioxide has a smaller and tighter unit lattice and a larger refractive index than anatase titanium dioxide, so that the hiding power and anti-Ultraviolet performance are obviously better than anatase. for the similar type of rutile titanium dioxide white masterbatch, The titanium dioxide has a small particle size and a narrow particle size division. The hiding power dispersed in the masterbatch is obviously wider than the titanium dioxide particle size distribution, And the dispersal in the masterbatch is poor. it's great. in the same manner, The hiding power of common calcium supplement carbonate, Barium sulfate, And zinc sulfide is also unique with titanium dioxide.

Table 1 Refractive index different substances

It can be seen from the above refractive index comparison that the difference between the refractive index of the rutile titanium dioxide and the carrier PE resin is large, The distribution effect is good, And the hiding power is the strong food coloring power.

3. Dispersibility

Dispersibility has an important effect on the effective use of titanium dioxide in plastics. in most cases, The finer the allergens of titanium dioxide, the higher the dispersion, And greater the tinctorial strength. towards the film needs fine printing, Use a white masterbatch with top-notch dispersibility. The pattern classification, Gradation and vividness from the grains are better. This is because the microscopic smoothness of the base film is one of the determinants of products you can the printed patterns.

4. fluids content

The moisture content in the white masterbatch also has significant effect on the performance of the masterbatch. ordinarily, The moisture content should be operated below 1500ppm, And the necessity should be strictly below 600ppm. In the procedure molding process, The garbage are generally dried before production In the film production, Customers buy it and use it directly after premixing with the carrier. If the fluids content of the masterbatch is high, It will at once lead to film rupture, And there will also be defects such as small bubbles and crystal points on the film. whenever you know the high moisture content of the white masterbatch is influenced by the raw materials selected for the masterbatch and the process.

5. scent

Some film companies will smell a strange odor after using white masterbatch. this is not allowed in milk films and food-bit films. This is mainly due to the organic management of titanium dioxide in the masterbatch. along the way, The coating aid selected is not good enough or the amount added is too large, Or the dispersant selected in manufacturing process of the masterbatch is problematic, The white masterbatch grade can swapped out.

6. Hue selection

Since rutile titanium dioxide has a low reflectivity in the violet site, Rutile titanium dioxide has a yellow-colored tint. The yellowish tint will give the coloured product an old look and reduce the vividness and layering of fine printed images. This is negative among many white masterbatch users, But adding several fluorescent whitening agent to titanium dioxide can absorb ultraviolet light with a wavelength of 300400nm and convert it into blue fluorescence with a wavelength of 400500nm. The whitened masterbatch is blue, And users of white masterbatch are looking at it according to their needs.

7. liquidity

The fluidity of the white masterbatch can be listed as the melt index (MI), the is low, The flow massive difference is high, the quality is high, And the fluidity is a good example, indicates good processing performance, Low peice of workout equipment torque, And low power uptake. at the time, in combination with requiring good flowability of the masterbatch, It should also be observed that the melting index of the masterbatch should be suitable for the carrier resin in its own factory products. The general principle would certainly MI of the masterbatch is higher than the carrier resin.

8. Printing heat sealing total

White film products require printing and heat sealing and, sometimes. young kids calcium carbonate to the white masterbatch will affect the clarity and vividness of the printed pattern. Incorrect or excessive dispersants added to the masterbatch will also affect the heat sealing and Printing productivity.

9. Light and weather resistor

White masterbatches generally desire a lightfastness of 78, A weatherability most typically associated with 45, And a ambient temperature resistance of 280 degrees. These requirements mainly depend on products you can titanium dioxide. to achieve the above conditions, Rutile titanium dioxide is employed.

10. RoHSFDA

Heavy metal testing and food contact approval are important too indicators of white masterbatch, Because many white films will be used in food wrapping, And passing FDA food qualifications is a mandatory test.

safety measures when using white masterbatch

1. so as to reduce the color difference of the fiber after color matching, The white masterbatch need to diluted, And the mixing ratio should be controlled. The filament is not less than 3% and 10%, And the staple fiber is not less than 1% and 3%. For spinning by color resources, The white masterbatch must be input within the extruder after mixing. in addition, In order to raise the mixing capacity of the melt itself, A mixing device may possibly be added in the extruder section.

2. The mixing method of white masterbatch After the color silk color formula is decided, The white masterbatch is evenly allocated in the polypropylene slices before spinning, Which is the key to ensuring the products the product. you can use two specific mixing methods. One is the extra weight method and volume method. post white masterbatch is melted in the extruder or at the rear, It is injected in the present polypropylene melt with a small extruder. The uniformity is pretty decent.

3. when choosing white masterbatch, It should be selected in line with the selection range. Polypropylene color masterbatch is split into fine denier and coarse denier. The white masterbatch color of coarse denier cannot used for fine denier color matching. in which monofilament denier of the fiber, Choose the white masterbatch of the grade.

4. The white masterbatch used is the product of the same business. In order to reduce costs, High awareness white masterbatch should be used. The white masterbatch pigments are split up into high, structure and low grades. When mirroring colors, Different grades of white masterbatch should be selected in accordance with the quality requirements of the fiber. In order to avoid the quality variation of the finished fiber due to multiple light and thermal stability of the pigment, The color of the white masterbatch using the same light and thermal stability level should be selected when matching the color.

Australian each and every make conductive plastic

on february 24th, Beijing energy, A new technology will have the ability to produce a plastic product with the properties of metal or even superconductor.



It is generally considered that plastics are quite poor in conductivity, So they are used to make insulating jackets for wires. of course, Researchers in Australia near Australia found that when an extremely thin metal film is overlaid on a plastic layer and mixed with ion beams on the surface of a polymer polymer, A good deal and high strength can be generated., Plastic film with good ruggedness and conductivity.



The team that achieved this result was led by two experts from the higher educatoin institutions of Queensland, sydney, professor Paul Meredith and Assistant teacher Ben Powell, And an expert Adam from the University of nsw? professor Michelin (AdamMicolich). Their feats have been published in the 'ChemPhysChem' magazine. The experiment on which the institute is based was conducted by Andrew Stephenson, A former doctoral student at the higher education of Queensland.



Ion beam technology is traditionally used in the microelectronics industry to test the conductivity of semiconductors, for example,most notably silicon wafers. suffice to say, Attempts to apply fractional treatments to plastic film materials only started in the 1980s, And have not made much progress until now. mentor Meredith said: The work done by this group is simply to use ion beam the computer industry to change the properties of the plastic film material so that it has a metal-Like option, Can transmit electrical current like the guide wire itself, Or even become a superconductor When the temperature is low to a certain degree, The prevention becomes zero.



In order to show the potential application value of this material, The team adopted this material and made resistance thermometers with regards to industry standards. as compared with platinum resistance thermometers of the same type, them made of the new materials showed similar or even superior performance.



The interesting thing about this material is that we retain almost all the benefits of high molecular polymer mechanical flexibility, High strength training, less expensive, But additionally it has good conductivity, Which is usually not a plastic should have benefits. teacher Mikhail said. this material has created a new world of plastic conductors.



And tim? Stephenson thinks fraxel treatments is exciting because the conductivity of this film can be adjusted or set, Which will enjoy a broad application prospect. he said: actually, We can change the conductivity of these components by 10 orders of magnitude. merely put, It is like we have 10 billion choices when making this fabric. theoretically, We can make plastics which are completely non-Conductive, Or plastics which were as conductive as metals, And all programs in between.



This new material can be easily manufactured using the equipment commonly used in today's microelectronics industry, And as opposed to traditional polymer semiconductor materials, This new material has much higher capacity oxidation when exposed to oxygen.



people said that combining these advantages, This thin film material obtained by ion beam treatment of high molecular polymers will have broad application prospects, And it is a fusion of modern and future systems. (company: readers' Network)

Product rewards of onboard active filter device

Ankerui Qiuhong Jiangsu Ankerui Electric manufacturing Jiangyin 2144051, Jiangsu Introduction recently, Power electronic technology has been regularly innovated and developed. Power electronic technology has been widespread in people's life, research project and work. commonly used charging devices and computers, federal express, and more. Are products of the introduction of power electronics technology. The invention and use of these units have brought great convenience to the society, But with the huge-Scale applying these devices, difficulty of power quality is also very prominent. Harmonics, As the primary ingredient that endangers power quality, Has been highly valued by all parties. funds many power quality solutions in the society, And a significant-Scale markets has been formed. Ankerui Electric is the leader especially. 2 are usually generation and management of harmonics? Harmonics generally refer to the amount of electricity inside the current at an integer multiple of the fundamental wave. we regularly say the Nth harmonic, And their frequency is the main wave. N occasions; In a wide sense, Any component that differs from the power frequency can be called a harmonic. in other words 2.1 harmonics are generated in a line filled with only linear components (challenge, for example.). The applied voltage is proportional to the current waveform as a sine wave. might cause of harmonics is due to the nonlinear characteristics of certain equipment and loads in the power system, which could, The waveform distortion caused by the non-Proportional union between the applied voltage and the generated current. When the power system supplies power to equipment filled with non-Linear pieces, These devices not only transform and absorb the power of the system, But also convert part of the fundamental wave into harmonics, Which is fed into the machine and pollutes the power grid. The lighting and TV screens that aren't unusual in life 2.2 Harm of Harmonics In the transmission and distribution network, Harmonics will reduce the capacity of the transformer and reduce the current carrying capacity of the cable. In dangerous cases, It will cause a sudden power being interrupted and cause major social and economic losses; In manufacturing companies, Harmonics can minimize communication signals, Cause component malfunctions, Reduce the soundness of equipment and increase the rate of defective products, And accelerate the aging of apparatus to shorten its service life. In intensive cases, It may damage the tools or even cause a fire. 2.3 Harmonic-Generating equipment the kit that generates harmonics is generally non-Linear items, Mainly divided into all of the following categories: (1) iron-Core equipment with ferromagnetic saturation attributes, such like transformers, Reactors, and so forth, (2) With solid non-Linear Equipment with linear attributes arc as working medium, Such as gas emit lamp, AC arc welding gear, iron-Making electro-mechanical arc furnace, stop smoking,give up, (3) Equipment based on power gadget components, Such as switching power, converter device, current regulator device, or anything else,.,and so.. Some commonplace harmonic-Generating loads and their harmonic content show up Table 1. Table 1 Harmonic content of common harmonic loads There are currently three types of harmonic control measures: receiving end control, could, begining with equipment or systems affected by harmonics, Improving astounding to resist harmonic interference; Active elimination, That is originating in the harmonic source itself, so your harmonic source does not generate or reduce harmonics; unaggressive governance, that may be, The external filtering device is used maintenance harmonics from being injected into the power grid. Passive governance is currently the most extensive harmonic governance solution.

2.4 There are two types of filtering devices added to the harmonic control plan, which are usually passive filtering devices and active filtering devices. They have their own disadvantages and benefits. The passive filter device has a simple design, Is easy to, And has a small initial investment, But can only filter a fixed number of harmonics and is prone to resonate with the power company; The active filter device has problematic structure and a high cost, But has a good damages effect and is easy to maintain later, Low up keep cost. as being a result, installing active filter devices is currently widely used harmonic treatment. 3 Product arrival of on-Board active filtering device ANAPF on-Board active filter device is a new type of electrical power compensation device I developed, Using modern power electronic devices technology, with high-Speed digital control digital signal processing service Special equipment for power harmonic control. It is made up of two main parts: Command current calculation circuit and reparation current generation circuit. Compared with tha permanent passive filter (such as providing a very low impedance channel close to 0 for the harmonic current to avoid harmonic current injection into the system), The active filter device realizes each harmonic by the IGBT inverter module Dynamic filtering. 3.1 Working principle of ANAPF onboard active filter device The ANAPF onboard active filter device can detect the load current instantly through an external current transformer, And through internal DSP formula, Extract and calculate the harmonic part of the load current, And then pass The PWM signal is sent to the inner IGBT, And the inverter is controlled to come up with a harmonic current equal to the load harmonic current, And the harmonic current in the other direction is injected into the grid to cancel the corresponding harmonic current to achieve the purpose of filtering. The working principle diagram and pay out diagram are shown in Figure 1. Figure 1 ANAPF working principle and identical waveform schematic 3.2 Structure introduction and advantage analysis of ANAPF onboard active filter device unlike the previous cabinet products, ANAPF onboard active filter device is smaller in size and brighter. you can certainly install and more beautiful, Which has higher must have on product structure and internal integration. The ANAPF active filter device produced by our company is divided into two setup methods, And its main parameters are listed below: each side the wall-attached to-Board component is shown in Figure 2: The external dimension 485275610 (thicker, Depth and size) Rated of the latest: 50A (Can be appropriate to be able to demand) (bring up) Rated current: AC380V electric method: three-section three-insert or three-time four-Wire inlet solution: Upper and upper rated happening: 50Hz element shell color: RAL7035 basic safety level: IP20 quality: 50KG determine 2 wall-placed board-Mounted appearance schematic drawer the appearance of the on-Board component is shown in Figure 3: proportions 485610275 (width, Depth and level) Rated previous: 50A (Can be correctly increased according to demand) Rated voltage: AC380V wires method: three-factor three-wire or three-level four-Wire inlet form: Backward Rated rate of recurrence of the rear output: 50Hz module shell color: RAL9004 proper protection level: IP20 large: 50KG discern 3 Drawer on-Board general look diagram where the wall-Mounted structure is worthy of occasions where the load capacity is small or the site is compact, It is generally recommended to run partnerships When used; The drawer structure mostly adopts the installation method of multiple modules set up on parallel in the drawer cabinet, Which can increase or decrease the number of modules in the cabinet depending on actual compensation capacity demand, Which is best with occasions with large load capacity. at present, Our company's conventional product is a mix 6 modules, And it is finding and developing towards more modules and larger capacity. The arranged up effect diagram of the drawer cabinet is shown in Figure 4. Compared with the cabinet type, This method has another advantages: (1) the proportions of each module is 50A (Which can float within an appropriate range), advantages capacity options under the same cabinet structure, And it can be based on the actual needs of customers Increase the number of modules to more than 6 (The cabinet size really should be widened, the effects can refer to Figure 5); (2) The capacity of the APF device can be increased or decreased at any time according to the changes in load usage (Add or subtract may modules, And the corresponding parameters are set on the machine interface); (3) Each module is installed with a cooling unit apart, And a cooling fan can be attached to the cabinet, The cooling effect is, And the failure rate is low; (4) although there are communication connections between multiple modules, But the failure of each station will not affect the other modules to go on to work (The compensation capacity will appear reduced accordingly); (5) Convenient cleaning at a later stage, The faulty module can be repaired and replaced one by one; The ANAPF active filter device can work frequently during maintenance. (6) The structure is exquisite and the structure is flexible. It can be obtained separately as a component (module) And embedded in a third-Party pantry; Changes in the cabinet's appearance and dimensions will basically not affect the inner installation and overall use effect. (7) manufacturing cycle is short, Even the products with unconventionally requirements can be guaranteed to be put into use in time to ensure the economic benefits of customers. Figure 4 Schematic diagram of modular combined installment



Figure 5 Schematic diagram of the gathering effect of two-Row modules It is intuitive to see the reparation effect. The harmonic current content after pay out is only 4%, Which is lower than the national standard requirement of 0.38KV power company 5%. Taking phase C by way of example, the related harmonic content list is as follows: Before damages, Each harmonic content of phase C is compensated The harmonic content of each phase of phase C can be seen from the waveform to see the a settlement effect more intuitively: The current waveform before cost is M-carved, And after compensation has turned into a sine wave, the consequence is good. Voltage and current waveforms before remuneration 3.4 Voltage and current waveforms before pay out 3.4 The model selection of the ANAPF onboard active filter device this product is a parallel type active power filter, that is named: The size of the harmonic compensation current can be arranged before professional sale The engineer assists in the measurement or selects it while using transformer capacity and industry type, And the calculation method is shown in formula (1)., medicine (1) could be the transformer load factor, may well, The load the number of the rated capacity of the transformer is usually 0.60.8; It is the total harmonic distortion rate of modern, Which is slightly different in various establishments. For a variety of values, See regular 1 above; it's the rated capacity of the transformer, near KVA; 0.380.4.4 Conclusion on such basis as the original vertical cabinets, drawers and wall-Mounted treatments, The ANAPF onboard active filter device further reduces the volume and weight; Due to its highly incorporated module design, Later maintenance becomes simpler, handiness, And governance effects are more vast. it can not only control harmonics, But also recompense reactive power: the right way control harmonics, Improve power quality and greatly reduce the equipment malfunction rate, Thereby improving the use rate of electrical equipment and product qualification rate, Which not only ensures the safe operation of the power company, But also Can reduce anyone's power loss; And effectively atone for reactive power, So that the power factor is often 0.98, So as to avoid users being fined due to insufficient power factor, But also bring sizable economic benefits for users. It can be seen that picking a ANAPF onboard products has great benefits for power grid facilities and user equipment. It goes that it achieves a win-Win situation for both power supply and power users. guide [1] Ankerui power quality pursuing and treatment selection manual. option 2015.08 [2] Ankerui all electric Product Manual. variant 2013.01. about the writer: Qiu Hong (1990), customer, basic, professional, The main research direction is intelligent building power and distribution monitoring system

opening of installation method of cycloid reducer

The general cycloidal pin gear reducer is put into flanged and special motor direct connection type. The flanged ordinary motor directly separates the motor and flange connection part. It is far easier to disassemble, And it is generally not an issue. Motor direct relationship,contact type Generally, Put the end of the motor upright among the bushes, eliminate it from the end of the output shaft, remove the oil seal, your end cover, And then go for the pendulum, peculiar bearing, And needle shell in series, and you're almost done. General disassembly is no worries, But the cycloidal pinwheel reducer is very a variety of when it is installed, particularly the pendulum must not be installed incorrectly. when buying the cycloid, it's necessary to check whether the two cycloid wheels are a pair. Cycloid wheel construction It is based on a pair (thats generally, One commission). The purchase can be another pair or one payment, One any money. The single cycloidal pin wheel of each payment cannot swapped out, And the two pieces of the cycloid wheel are in the production process. The two are not lost. The concept of a pair would certainly two cycloid wheels can completely overlap (might be, When the side with the steel printing is overlapped and placed likewise), the particular bearing hole, The ten abyss (base pin hole) And the foreign tooth shape. Completely coincident. It compares with one piece from the front. If it can completely agree, It proves to be a pair, And it cannot be coincident. It means that must be not a pair and cannot be used. loan. The cycloid wheel is in any event. The marked side should be facing up. The marking of each pair of cycloid wheels is also various. The position of each manufacturer's typing number mark is different. The marking position of domestic vendors is generally the coincident position mark, (The mark position correlates), But remember, there are installation position marks. no matter where the mark is, It is just Help test mantra of sophisticated a pair of rounds of auxiliary means.

Rotate some of the cycloid wheels 180 degrees. surely, When the center bearing hole and the ten holes are completely coincident, The external tooth shape is exactly out of alignment. The position of the tooth heel of the upper piece is the position of the crest of the lower piece. card. The relative position of the must be loved. Draw a mark your own. Or remember the position of the original mark on the wheel. (This is a cycloid wheel with a single tooth improvement. There is no need to turn 180 degrees for a double tooth difference)

Put a cycloid wheel into the needle tooth shell. Turn it by hand to see should it be smooth. whether it swings.

Put the unusual bearing. Because the bearing hole of the cycloid wheel is equivalent to the outer sleeve of the eccentric bearing, The correct position of the eccentric bearing is that the bearing hole of the next cycloid wheel just completely contains the cylindrical ball of the eccentric bearing.

make the spacer ring. It is an iron ring less space-consuming than the cycloid wheel, (Some turn out not iron now)

Put another joint of cycloid wheel. It extremely important when putting this wheel. The stenciled word of this cycloid wheel must be as the word of the cycloid wheel underneath, And the two cycloid wheels must be around. The stenciled classes are exactly 180 degrees apart, plus they're placed on a straight line, Not the characters of the upper and lower cycloid wheels. This point should be paid special attention to! (pay attention to: Some designers have already installed the coincidence mark on the cycloid wheel. It is the best, But all the cycloid pin gear reducers made in Changzhou require staggered by 180 degrees!)

Put the shaft sleeve in the outlet of the cycloid wheel. Turn it by hand to see if it truly is rotated. Check whether the install is correct. If it rotated smoothly, You can install the base part to synthesize the whole cycloidal pin gear reducer Oh, huh! at that point, You is quite possible

It is assembled by two treatment parts of tearing cover and box seat. selecting their plastic materials, The design of the anchor text between each other, And the arrangement and structure of the tearing groove must ensure that the tearing box cracks and the airbag pops up when the questionable expands. The structure of the product is complex and requires reliable function and performance. as a, the look of injection molds must use hot runner technology, And perform mold filling flow analysis to ensure the quality of injection molded products. 2 Airbag protection Most cars produced in various countries include airbags. The airbag at the driver's seat is stored in the steering wheel lining, And the controls tear box is marked with SRS or Airbag. supplement Inflatable Restraint System (SRS) Is mainly characterized by sensors, Microprocessors, Gas generators and airbags. Sensors and microprocessors determine the degree of collision and transmit and send signals. The gas generator generates an ignition action using the signal. The solid fuel is ignited and gas is provided to inflate the airbag, causing the airbag to inflate rapidly, With a capacity starting from about 50 to 90 liters. The growing force of the airbag ruptures the torn cover. publish the impact force evenly to the driver's head and chest. The airbag sensor must have an adequate amount of impact force to activate the switch. This impact force is approximately equal to the result of hitting a fixed object at a speed of 2550 km per hour. When the car collides at a high speed, The sensor can detect the sudden deceleration of a pick-up truck speed, And quickly transmit this signal to the control computer for confirmation before detonating the electric igniter in the airbag package, inducing the airbag to inflate rapidly. The airbag is also with a safety valve, Which will robotically bleed part of the gas when the over-Inflation or the interior pressure exceeds a certain value, To avoid crushing and hurting you. The microprocessor must also work within 0.01s after a car wreck, The ignition device starts in 0.03s, health benefits-amount of force gas enters the airbag in 0.05s, And the airbag fills up outward in 0.08s, Breaking through tear cover. all the way through 0.11s, The inner bladder is fully inflated and attached to the human body. present ideas for wedding, the driving force will be protected by the airbag. 2.1 the design and style of the airbag box is shown in Figure 1. The tyre airbag box is made of a torn cover and a box seat. The airbag box is installed in a bracket involved with the driver's steering wheel. benefit-Pressure gas enters the airbag to fully inflate only 0.06s. It must be ensured that the torn cover on the airbag box is broken by the water airbag and allowed to pop up and expand. The box seat must not be broken. the hyperlink between the tearing cover and the elastic clip of the box seat must be firm. that the airbag is inflated, The tearing cover and the plastic of the box seat mustn't break and fly out, contributing to accidental injury to the driver. likewise, The tear box and the lining of the steering wheel must also be firmly connected, so the airbag and the tear box cannot fly out, Injuring the driver. Figure 1 When the airbag in the controls airbag box is inflated at high pressure, The shape of the rupture of the plastic cover depends on the division and structure of the tear groove on the inner wall of the tear cover, As shown in cost 2. The total length of the tearing groove is 540mm, There are circumferential grooves with a circumferential angle of 270 in the center, And there is certainly four radial grooves with a length of 50mm, And four outer circumferential grooves that are not continuous mutually. When the airbag is inflated and tears down the groove, The synthetic cover is opened like a petal, And the split film is connected to the cover without broken plastic pieces. To permit the airbag to pop out, The wall in tear cover is 3mm thick. The width of the tear groove is influenced at 0.4mm. density of the bottom wall of the tear groove is 0.5mm, And the error of the bottom wall thickness over the entire length must be less than 0.05mm. huge-Precision tear density can ensure fast cracking response. The oblique cone angle of the tearing groove is operated at 322. 2.2 ingredient of the tearing cover and the box seat The tearing cover adopts the new material of polyolefin-Based thermoplastic elastomer TPO. With its low modulus of firmness, simple to tear, And good firmness, expense damage the airbag when it is inflated. The tear cover elastomer has a Shore D solidity of 37. as 23, The elongation at wreck is 560%; The bending modulus of suppleness is 205MPa; The shear motivation is 14MPa. PA66 40% GF for box display rack. The glass fiber a sturdy polyamide has an elastic modulus of up to 634011400 MPa, Which is dozens of times higher compared to the torn cover material. The wall wider of the rigid box seat is 3.2mm usually. When inflating at questionable, Ensure that it will not break. 2.3 Elastic clip net connection As shown in Figure 1 and Figure 2, In order to meet the quick assembly expectations of the assembly line of the car, The tear cover is gathered together with the box seat, And the tear box is assembled with the steering wheel liner, All using cantilever supple clips. Using the bending elastic deformation generated by the protrusion of the cantilever column bar, The elastic column bar on one plastic part is snapped into the square hole groove of another plastic part. Figure 2 The distribution of the tear grooves in the wall of the tear cover is to be certain that the post is not pulled off when the airbag is inflated. The cantilever elastic post was created on the high-resistance box seat. As many as 13 elastic clips are connected within box seat and the tearing cover. Between the cover seat and the controls lining frame, The connecting square hole groove of the elastic clip is designed on the glass fiber reinforced box seat. and place 1mm thick metal inserts in the two square holes. In order ensuring that the elastic column is guided and positioned during quick assembly, A placing pin and a side groove are also designed. this makes the mold structure have both the outer slider side draw, As shown in body shape 3, And the inside of the slide rule of the inside, As shown in person 4. Figure 3 Outer sliding mechanism of box base moving mold Figure 4 Inner sliding mechanism of box base moving mold Slider 3 Design of injection mold Considering certain requirements for quick assembly of injection parts, High perspective accuracy, Tear cover and box base treatment mold for one piece. The molded parts of these two molds are created from German 1.2738 pre-hard steel. which could, The German brand 40CrMnNiMo8 6 4 is the same as P20 Ni. the outer hardness of molded parts is HRC3034 to achieve a service life of 500,000 nights. The torn cover is also called the decorative cover of the tyre. After the corrugation of the cavity top of the mold is corroded, it can nitrided. 3.1 The hot runner hi-tech is used to tear the cover and the two injection molds of the box seat, And both adopt single point hot runner mist nozzles. The cavity filling amount of the tearing cover is 155cm3, And the cavity volume of the box seat is 187cm3, And the flow ratio is comparatively small. which means, traditionally, These two molds do not use hot runner the computer industry. The application of hot runner nozzles can reduce the pressure loss of the plastic melt in the way, Which is helpful to the injection and the transfer of the holding pressure. Make the density of plastic gadgets uniform after cooling and solidification. This is beneficial to improve the dimensional accuracy of plastic parts. For the break of the tear groove bottom; The tensile strength of the cantilever elastic column is beneficial. The injection mold for the tear cover in Figure 5 uses the BS25070 single nozzle maded by KLN. The length of the thimble gate is 1.6mm, And the gate hole is set on the template. The trace of the gate is smaller. The mist nozzle is 83mm long, Which saves a lot of TPO plastic condensate in the hard drive. Figure 5 The hot runner main nozzle of the tear cover injection mold Figure 6 The pouring system of the upper box injection mold uses the SP25135 single nozzle generated by KLN. This hot runner nozzle has ball dimples that fit the nozzle head of the treatment molding machine. The diameter of solitary pilot is a nozzle is 6mm and the length is 122mm. Large gate with famous channel for single nozzle. the little end gate of the inverted cone has a diameter of 3mm, A time period of 22mm, And a large end dimension of 6mm. The gate is sleeved the particular nozzle. Downstream are three cold sporting men and gates. The runner mixture is only 2cm3. The use of this sort of mainstream hot nozzle and pouring system mixed with cold runner saves a lot of runner condensate. The hot runner and large gate reduce the stress loss in the melt flow. Improved the transfer of injection and holding pressure to the cavity. Also avoid defects include things like vacuum bubbles, shrinkage and flow marks caused by large gates on injection molded parts. Figure 6 Injection pressure distribution of the flow research into the box base 3.2 Moldflow analysis of the box base using computer simulation of the mold flow analysis technology, the recent runner nozzle and its main channel gate, hooking up three radial cold runners and side gate, As shown in believe 6. the new runner keeps the plastic in a molten state, And the pressure indication to the cavity is good. where the melt filling of 1.615s is finished, the pressure of the box cavity is shown in Figure 6. There is a questionable of 23.6MPa on the gate. The end problem of zui far stream is 11.416.3MPa, And the end stress and anxiety of other streams is 20.322.3MPa, pressure drop is small. After holding amount of force and cooling, the material density of the box base is uniform. The Moldflow analysis of the tear cap was performed using the performance data of the thermoplastic elastomer TPO stored in the software. Figure 7 shows the temperature circulation of the injection molded part at the end of 0.851s melt satisfying. There are only 23 hot and cold temperature differences across the plastic parts. your elongation at break of the elastomer is large, the content head in the gate is not easily broken. The customer suggested that the gate should be placed quietly wall of the tear cover, And the gate are to be cut off by ejection. based on Moldflow analysis, The gate is placed in the middle, And the temperature and pressure in the cavity are evenly distributed. you are able to, The air in the cavity is compressed to the parting surface and the positioning of the ejector rod, Which is beneficial to exhaust, As shown in statue 8. The nozzle is a smallish gate with a thimble. As long as the high temperature in the gate area is correct, The gate of the gate will pull off properly. And because the gate hole is set on web site of the cavity, The traces left on the top of plastic part are very small. for anyone who is undesirable phenomena such as visible flow marks and layering.

evolution to eight common molding processes

1. co-treatment molding (Core layer injections molding)



having co-Injection molding helps to see the unique structure in the part. Plastic A is injected to fill section of the cavity first, and therefore plastic: B follows the injection of A into the cavity and maintains the initial flow pressure field. good size of the skin area and the core layer, The amount of materials used for A and B is measured in accordance with the correct proportional relationship, And an inner core layer can be prepared as a part in which the outer surface of A is utterly wrapped by B.



as well, In cosmetic application submissions, a small sector of the cuticle nail material is placed after the injection of the B material, So that the cuticle organ of the cuticle can be completely closed. A creation that is co-procedure molded with two different colors of resin to form an easily distinguishable skin and core layer section (It is important to recognize that there's a similar skin and core layer in all injection molded parts.) If not With advanced detection software, It is often difficult to distinguish the area of ​​the epidermal core layer and its interface.



co-Injection molding is not a new process solutions. British ici began to apply fraxel treatments in the 1970s, And obtained several items concerning basic theory, Production companies machinery equipment. The commonly used ici production process is similar to sandwich molding. Because the material of the molded outer skin is completely different from the material of the middle or core layer, The two materials must have certain compatibility, And the core material want to really standout a high degree of radiation, Foam molding and recycling operation. Selection of materials should count on comparison of multiple options. Fifteen years following on from the co-shot molding process came out, It was truly prominent. A fold-point is made by thick-hypodermic injection molding by co-shot molding.



The skin material is bare nylon, as the core material is glass beads filled nylon. The shrinkage rate of the glass beads in the core layer is especially low, And it has good perspective stability. The nylon skin gives the gear teeth good lubricity and avoids the abrasion problem that the beads tend to form.



using the basic theory of co-hypodermic injection molding, Several new processing results have been developed. as an example, during-Mold painting like a pro and gas-Assisted molding have expanded the scope of this kind of. you see, the in-Mold piece of art process uses low molecular weight polymers as the outer layer material, whereas gas-made it easier for molding uses nitrogen or another gas as the core layer (Or the main core layer) wood. With the continuous advance and improve of product design and production and processing equipment, It will meet the needs of various new applications and new technologies. corp-Injection technology will surely become a promising developing large-Scale making process.



2. gas-Assisted treatment molding



that gas-Assisted injection molding modern technology is gradually developed to reduce weight and / or save cycle time.



in common co-treatment molding, The outer layer material is first injected and the cavity is only partly filled. Then the gas is injected through the nozzle or into the mold cavity, The core a part of the mold cavity. Liquefied gas can also be injected into the core part as soon as i've to be formed. essentially, The gas pressure in the core layer pushes the melt forward until it completely fills the cavity, And prevents the outer lining layer of the part from recessing from the cavity wall during the curing stage, And the connected skin layer is closely coupled to the cavity wall. It is stored in the core a part of the molded part. Since pressure of the injected gas is higher than the atmospheric pressure, the stress of the gas must be reduced before the part is ejected, So as to avoid deformation of the part when the cavity wall that provides for a limit moves.



Highly compressed gas is difficult to control its shape and position of the gas core, But with the continuous enlarger of processes and procedures, Qualified parts can be produced repeatedly.



Under the health of machine control, few controlled by various process procedures. With the continuous deepening of the basic theoretical research of injection molding doling, The method of control pressure is eliminated under the control method and real process control is adopted to monitor, Adjust and even control the response of martial arts. Improvements in processing parameters such as injection rate will have a primary impact on the molded parts, Especially their mechanical qualities and surface rentals. It is critical to comprehend that the injection rod speed is not equal to the melt injection speed. The response of the viscoelastic material and the pouring process can be related together, And have to synchronized. in other words, It is impossible and unrealistic to directly observe the response of the material. over the past, organizations reproducible sequence processing or control devices. The key step in this procedure flow is often to use dry cycle measurement equipment. may possibly molding processes are of course important, But priority should be given to reproducible melt similarities. which means that, as well as required to add an auxiliary detector on the controller to save and record the pressure and temperature of the plastic melt, Which is a vital parameter related to the melt condition, But it is not enough to adjust the nonlinear response of the information presented. Auxiliary adjustment and control equipment is being developed and applied to form highly complex injection molded parts. for example, a mechanical valve-proscribed gate is used in a hot runner system, Which can better regulate the division pressure in the runner, And can eliminate weld marks reducing warpage.



3. Low pressure injections molding



below average-Pressure injection molding has appeared in recent surveys on processing technology. furthermore, wedding ceremony a new process, But the processing method used can make your machine process better match the expected melt response. Under basic molding conditions, The melt initially undergoes a huge instability due to excessive compression at preliminary injection. this leads to a sharp increase in viscosity, And in addition the melt stores elastic energy due to compression. contrary to the low-Pressure shot molding process, The melt flows together with nozzle and the runner. your viscosity of the melt increases with increasing pressure, And the viscosity of and can-Pressure injections molding melt is low, The viscosity flow capabilities of the melt can be better controlled. also, The faster the pressure of the melt in the cylinder increases, if more solid-Like empty body response looks. The process of viscoelastic plastic melt from pure liquid to pure solid has wide frequency response attribute. The specific quality of the melt response or relaxation time are determined by the chemical composition of the polymer backbone. Avoiding sudden changes in flow conditions or large changes in instants is more conducive to forming the specified liquid-Like aspects. genuinely, down-Pressure injection molding is just a processing method to master or adjust the viscoelastic properties of plastics. Resin models generally reduce the molecular weight of high-Fluidity resins in order to reduce their viscoelasticity, Which is suitable for producing thin-Walled components. With the deepening of the understanding the processing environment, the utilization of low-Pressure injection molding will make the plastic melt more adaptable to the needs of the production environment.



There are currently several industrialized products that use low-Pressure treatment molding. Most design projects have centered on combining low-Pressure procedure with re-procedure plastic molding. as an example, The molding of automobile door interior panels is to place woven or non-Woven fabric inside mold, And then directly inject the melt in the mold. in just-Mold labeling is another molding method that goes past simple printing. At the start of each cycle of production, Individual labels or successive films can switch positions about the mold. and also being printable, The film has a lot of kinetic energy every now and then (Such as high-impact resistance, severe resin) Or the film may contain additives and stabilizers to protect the top of molded part.



4. Alternate injection molding



differing, Alternating injection is a relatively recent injection molding selection parameter. The major difficulty of fractional laser treatments is that when processing conditions change suddenly, Little is known about how precisely the plastic melt will behave. The basic is crucial melt rheology is not just a fixed shear viscosity. primarily, The functions of the melt response (Viscous and elastic behavior training) requires to be expressed, Not only the standard steady-State flow rate or shear rate and warm, But also the pressure and instant flow rate. These features include a lot of content and are really hard to figure out. still, If substantial progress is made in the injection of profiled materials, Specific operating procedures for many different plastics will have to be worked out. Also need to increase the general experimenting method, so that it will get mature and control methods.



In the typical injection molding, The cavity wall is fixed, and in some cases, it is additionally used to move the mold wall in the filling and pressure holding section. Two different methods can be used: Moving the cavity wall direction verticle with respect to the parting line; turning or sliding the cavity wall. Rotate the core during the mold filling stage to expand the variable axis orientation of the molecules, specially the skin part. Through this processing hi-tech, The bending play and other mechanical properties of the parts have been greatly improved. Polystyrene drinking cups and polypropylene syringes are two products that have undergone major changes through this processing method.



5. Injection compression molding



In injection data compresion molding, The moving direction of the cavity wall is perpendicular to the parting line. When molding by particularly expensive, In the completing stage, Pressure is generated while using process to drive the melt flow, But the depth of this flow channel is shifting. In the deeper flow sales channel, pressure drop is lower, so that the melt is not excessively compressed during the molding of large-Area pieces, And the immediate material response is avoided. These two factors also will hinder the flow of the melt. through the injection molding process, The cavity depth may be 14% of the thickness of the final product. After the plastic fills possibly even 60% to 75% of the cavity, The injections is stopped, And the walls around the cavity are all at once pushed until the final product Until the original wall is formed. The final size of the product is established at this stage.



If the cavity is filled before the mold wall moves while using process, this situation is usually called casting. for the most part, Casting is to keep the various components under constant pressure in a variable-volume level cavity. The casting stage is the stage of increasing the density, And the density then changes concerned with the melt and the solid plastic. The compact disk is formed by casting method, Which can reduce the residual stress to the lowest level, And the residual stress on the workpiece can create a variable refraction phenomenon.



The improved movable cavity wall of casting molding is a new development, Which is through the porous metal cavity wall in the solidification stage of the injection system to maintain the pressure. this technique has been called external gas-made it simpler for molding, But this is actually a misunderstanding, Because the gas does not affect the flow of the plastic melt in the cavity. In normal injection molding, Holding pressure is to add more plastic under the effect of pressure flow while keeping the cavity volume unchanged. in the pressure-clutching flow in the cavity, An uneven pressure distribution is formed, Which may cause part defects at the gate location subject to underhand.



6. cooling down of the mold



Mold cooling is a key process machinery. much of the molding cycle is conducted by conductive heat transfer process. The energy can be brought from the hot melt to the cold mold due to the temperature difference. The plastic skin along the side of the mold effectively isolates the core layer, Making this particular heat transfer very inefficient. conversely, Mold cooling is not often noticed until after the design stage. A better cooling design style can shorten cycle end production time by 20% to 30% or less, And improve labor generating.



During creation cycle, The surface temperature of the mold changes continuously and occasionally. When the hot melt presses resistant to the mold wall, The mold temperatures are high. right ejecting the part, leading to a next injection, The cavity The mold temperatures are low. to be shorten the cooling time to the lowest limit, People have been looking for the lowest mold high temperature range that can produce qualified parts. The important role of mold temperature is to affect the melt flow in the cavity and the size ratio between the skin and the core layer. The lower the mold setting, The thicker the skin size and the greater the stress drop in the cavity. The pulse cooling technology is a technology that usually uses very frozen frozen liquid in the circulating cooling tube to adjust the cooling after injection of plastic into the mold cavity. after the part is ejected, If there isn't circulation, The temperature of the cavity wall will rise appreciably after the next shot melt flow enters the cavity. After the pulse cooling method is adopted, The temps of the cavity wall will be higher, But it is slightly lower than the temperature detected by the common mold cooling method. Pulse cooling can be widely used in the forming of thin-Walled work pieces; The forming of parts which need repeated surfaces, And the sudden change of material in to select from of the depth of the flow channel. as an example, Stagnation airflow. towards processing advantages of pulse cooling and other potential limitations in terms of potential advantages, The debate about whether or not the cost of pulse cooling is too high has become less important.



7. Melting core forming whole process



Fused core forming method is a quite recent process method, Which is convenient for processing parts with complicated channels, lines or lines inside. businesses of small parts such as pipe clamps, Pump housings, And sports goods started contemplating of whether to use this process as early as 15 years ago. in recent months, Auto creation has adopted this process to produce large parts such as lightweight power system samples and intake manifolds. This core has the function of a foldable core like an established mold, And receives an insert core with a defined inner cavity wall. the visible difference lies in the structure of the core, Which cannot be disassembled in the mold or drawn out of the mold by mechanical methods. further, If such type of core is not melted by inductive heating, maybe a low melting point (138oc) jar-Bismuth alloy or another tin alloy, It is laundered away by (disolveable acrylic polymer) In the second procedure. this much melt core molding adopts conventional processing methods. the actual between the two lies in the thermal performance of the core and the cavity material. The thermal performance of the core directly affects density of the core structure of the flowing skin on the part. as per the actual processing conditions, The thickness of the top and bottom skins can be completely different. often, Warpage imperfections may occur, While in other instances, The warpage of parts that are prone to defects may be reduced or fired.



In the melt core developing method, The core only is the mold wall. The filling process would not change due to solid inserts. Since the thermal properties of metal alloy cores or polymer cores are distinctive, the desired pressure is also different. The polymer core acts as a barrier and helps to create a very thin fluid skin in the molded part; The metal core becomes a heat dissipation point and forms a relatively thick fluid skin on the part. If the top core is melted when the plastic melt flows through, important change in flow will occur. it is often reported that icicles are used as cores. Before the liquid film has a very very confusing processing problem at the interface between ice and plastic, This method is sensible for high-finely-detailed parts.



8. notebook computer or computer-Aided molding



Using program-Aided executive (cae) For process design and analysis helps shorten the planning cycle and avoid costly mechanical errors. Commercial simulation codes can be used to mark the dimensions of the runner to balance the flow of melt in the runner system and cavity, And to look for the best opening setting and the number of gates for the gate. The calculations of injection pressure and mold tonnage depends on different processing conditions and materials. The shrinkage rate and warpage rate together with the initial flow direction can also be accurately estimated. it's critical to make this design tool to help skilled analysts make judgment operations in a certain design scheme or processing research. The result must be understood as the premise of your analysis object and processing / material. When considering that way to input data accurately, Huge benefits is the answer. required,as an affiliate, The economics of this analysis can cause shorter design cycles and shorter production times.



It should be observed that commercial cae programs are usually not directly usable. Mold filling simulation can produce valued insights, But effects must be reconsidered to estimate its limitations. Use modern computers for treatment molding simulation tests on pure viscous fluids (forgetting viscoelastic molten plastics). It can predict i would say the flow rate of melt into the cavity. The structure, Structure as well as are announced, instance high-precision viscoelastic analysis. Any other processing method currently used is unlikely to reach this advanced level, And recently, The industry leader in simulation equipment and research teams in schools have made good progress. Several companies are working hard to explore simulation methods of order to correctly explain more realistic plastic behaviors and processing phenomena. for example, The influence of the orientation of the polymer backbone on local physical properties and gratification distribution. Processing physics is very tough, And some viscoelastic phenomena are still not fully defined, And more complete and cheap processing methods are slowly forming. These out of this world methods will achieve a production capacity that greatly exceeds the current design.

Chaojie analyzes the operation steps and industry prospective business partners of high-Speed machines

The alias of top-Speed mixer is identified as: fantastic-swiftness mixer, large-associated with mixer, raised-machine, better-decreased-acceleration and speed mixer. advantages-Speed mixer is principally used in plastics, Building books, plastic, tones, pharaceutical medication, Chemical industries and the blending, mixing, Drying and coloring options of calcium powder, Resin natural powder, Polyvinyl chloride (faux wood) And many other materials. Friction cranks out heat, attempting to keep the uniformity of material mixing, Dispersity and adsorption features unchanged.

By endorsed and most credible and absorbing foreign advanced production technology, Chaojie Machinery has improved the production technology of high-Speed mixers. By adjusting the radius of the R angle of the bottom of the mixing mixer, The bottom has less material deposits, It absorbs cleanly, And the mixing blade and barrel The gap between the walls is properly reduced to avoid the pad sticking to the wall during the mixing process, so that the shear force is increased, And the friction coefficient of the material is increased to achieve the effect of rapid mixing. The gap between the mixing blade and the bottom of the mixing barrel has an adjustment range of 35 mm The equipment has a vector-kind inverter, that produces the starting current smaller, the equipment runs more smoothly, Saves capability, And has saved me power. on top of that, It can protect the motor and the main power transformer. The overall frame of kit is reduced, And the appliance takes up a small area. Good trustworthiness, No vibration at work, as well as convenient operation, Improved mechanization, No dust exposure during the mixing process, eco protection performance standards, very good-Speed mixer is probably ideal processing equipment for building materials, pouches, Chemicals and other market sectors.

at that time, In the operation of production and application, We should master some fundamental operating skills and methods. It is important too to grasp the basic theoretical knowledge of high-Speed appliances, such as operation of the main shaft, the mixing barrel, the blending blade, And the work of parts.
