塑料模具的分类（The classification of plastic mold） 1. injection molding (Injection Molding) refers to the heat melting the material by high-pressure injection mold cavity, after cooling after curing are molded method. This method is suitable for mass production of complex shaped parts, is an important processing methods of injection molding can be divided into the following 6 stages of mold injection mold cooling products packing out the process repeatedly, we can continuously produce products. The so-called 2. die (Mold) refers to the result of a certain shape of products of resin material into metal model. Other materials are plastic mould, plastic processing industry and plastic molding machine, plastic products to give complete configuration and precise size of the tool. Because of the plastic varieties and processing methods of various plastic molding machine and plastic product structure is simplified, so the plastic mold of the type and structure is various. For a combined plastic mold plastic pressure, extrusion, injection, blow molding and low foaming, which mainly comprises a die with variable cavity plastic mold die by the combination of substrate and die components and die combination clamping boards, die with variable core is composed of a convex mold substrate, punch, punch card, component combination cavity blocking assembly and side cutting plate. The coordinate change of the convex die, the concave die and the auxiliary molding system. Series of plastic parts processing of different shapes and dimensions. Plastic processing industry and plastic molding machine, plastic products to give complete configuration and precise size of the tool. Because of the plastic varieties and processing methods of various plastic molding machine and plastic product structure is simplified, so the plastic mold of the type and structure is various. With the rapid development of plastic industry and general and engineering plastics in the continuous improvement of the intensity
