For our plastic injection molding manufacturer, combined plastic mold for compression molding, extrusion molding, injection molding, blow molding, and low foaming molding, which mainly includes a variable cavity composed of a die combination substrate, a die component and a die combination card. The female die is a male die with a variable core consisting of a male die combination substrate, a male die component, a male die combination card, a cavity cut-off component and a side cut combination plate. With the rapid development of the plastic industry and the continuous improvement of general and engineering plastics in terms of strength, the scope of application of plastic products is also expanding, and the amount of plastic products is also increasing.
Process of plastic mold:
A plastic mold is a tool for producing plastic products. It is composed of several groups of parts, and this combination has a molding cavity. During injection molding, the mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, cooled and shaped in the cavity, and then the upper and lower molds are separated. The product is ejected from the cavity through the ejection system and leaves the mold. For the next injection, the entire injection process is cyclic.
Although the structure of the mold may vary widely depending on the variety and performance of plastics, the shape and structure of plastic products, and the type of injection machine, the basic structure is the same. The mold is mainly composed of a pouring system, a temperature control system, a molding part and a structural part. Among them, the casting system and molding parts are the parts that directly contact the plastic, and change with plastics and products. They are the most complicated and most variable parts of the mold, and require the highest processing finish and precision.
Application of plastic mold:
Driven by the high-tech drive and application requirements of pillar industries, China's plastic molds have formed a huge industrial chain, from upstream raw and auxiliary materials industries and processing and testing equipment to downstream machinery, automobiles, motorcycles, home appliances, and electronic communications. , Building materials, plastic mold development.
