Plastic mold manufacturing refers to tools that are matched with plastic molding machines to give plastic products a complete structure and size. There are many types of plastics, and there are many processing methods, so plastic mold manufacturing is also diverse.

1. Injection mold, it is mainly a kind of molding mold that can be applied and researched in product production through the design of thermoplastic parts. The processing technology equipment corresponding to the plastic injection mold is the plastic injection molding machine. The plastic first heats the barrel at the bottom of the injection molding machine. The inside is heated and melted, and then driven by the screw or plunger of the injection molding machine, the injection molding machine nozzle and the pouring operation system of the mold have entered the mold cavity, and the plastic is cooled and hardened to form, and the demolding method is improved.

2. Compression mold, a mold mainly used for forming thermosetting plastics, and its corresponding equipment is a pressure forming machine. The compression molding method heats the mold to the molding temperature (generally 103°-108°) according to the characteristics of the plastic, and then puts the measured compression molding powder into the mold cavity and the feeding chamber, and closes the mold. The plastic softens and viscous flows under the action of high temperature and high pressure. After a certain period of time, it is cured and formed into the desired product shape.

3. Extrusion mold is a kind of mold used to form continuous plastic products, also known as extrusion mold, which is used in the processing of pipes, bars, monofilaments, plates, films, cable coatings, profiles, etc.

4. Blow molding mold is a mold used to form hollow plastic container products (such as packaging containers for beverage bottles, daily chemical products, etc.). The main forms of blow molding include extrusion blow molding, injection blow molding, injection stretch blow molding (commonly known as "injection-stretch-blow"), multi-layer blow molding, sheet blow molding, and so on.

5. Blister molds are usually used to make some relatively simple products, using plates and sheets as raw materials. The principle is to use the vacuum blooming method or compressed air molding technology to make the plastic plate fixed on the concave mold or the convex mold. , Sheet, deformed under the condition of heating and softening, and attached to the cavity of the mold to obtain the molding enterprise products needed for development, mainly including the production of packaging design products for some daily necessities, food, and toys.

The above are several classifications of mold manufacturing. I believe you will be able to gain something after reading it. Friends who are interested in mold manufacturing may wish to pay attention to us.

Several elements in plastic molds

Time of issue : 2021-10-27 15:28:05

1. Parting surface: the contact surface between the plastic mold and the convex mold when it is closed. The choice of its location and form is affected by factors such as product shape and appearance, wall thickness, forming method, post-processing technology, mold type and structure, demoulding method and forming machine structure. 2. Structural parts: that is, the slider, inclined top, and straight top of the complex mold. The design of structural parts is very critical, related to product life, processing cycle, cost, product quality, etc. Therefore, the design of the complex core structure requires the comprehensive ability of the designer, and strives to pursue a simpler, more durable, and more economical design solution. 3. Mold accuracy: namely avoiding jams, positioning, guide posts, positioning pins, etc. The positioning system is related to the appearance quality of the product, mold quality and mold life. According to the different mold structure, choose different positioning methods. The control of positioning accuracy mainly depends on processing. The positioning of the internal mold is mainly considered by the designer, and a more reasonable and easy-to-adjust positioning method is designed. 4. Pouring system: the feeding channel from the nozzle to the cavity of the injection molding machine, including the main runner, branch runner, gate and cold cavity. In particular, the selection of the gate position should be conducive to filling the cavity with molten plastic in a good flow state, and when the mold is opened (except for the hot runner mold), the solid runner and gate cold material attached to the product can be very effective. Easily eject and remove from the mold. 5. Plastic shrinkage rate and factors affecting product dimensional accuracy: such as plastic mold manufacturing and assembly errors, mold wear, etc. In addition, when designing compression molds and injection molds, the matching of process parameters and structural parameters of the molding machine should also be considered.

Injection molding and temperature issues

Time of issue : 2021-10-27 15:26:05

The higher the mold temperature, the lower the flow resistance. On many injection molding machines, this naturally means that the flow through the sprue, gate and cavity is faster, because the injection flow control valve used cannot correct this change, and faster filling will result in a greater flow in the sprue and cavity. High effective pressure. May cause flashing. Since the hotter mold does not freeze the plastic that enters the edge area of the flash before the high pressure is formed, the melt will flash around the ejector pin and overflow into the gap of the dividing line. This shows that good injection rate control is required, and some modern flow control programmers can indeed do this. Generally speaking, a higher mold temperature will reduce the amount of plastic that has a condensation layer in the mold cavity, making it easier for the molten material to flow through the mold cavity, thereby increasing the weight of the part and improving the surface quality. At the same time, the mold temperature will also increase the tensile strength of the part. Mold insulation. Many molds, especially thermoplastics, work at relatively high temperatures, such as 80 degrees Celsius or 176 degrees Fahrenheit. If the mold is not insulated, the heat lost to the air and injection molding machine can easily be as much as the heat lost from the injection barrel. Therefore, the mold and the board should be insulated, and if possible, the mold surface should be insulated. If considering the hot runner mold, the heat exchange between the hot runner part and the cooling injection part should be minimized. This can reduce energy loss and warm-up time.

Model manufacturing is inseparable from high-precision molds, communication that developers cannot ignore

When developing products or trial-manufacturing new products, one should not only focus on R&D and neglect the communication with the model manufacturing unit. After the product design plan is initially determined, there are two advantages to contacting the manufacturer in advance:
