According to the different molding methods, the types of plastic processing molds corresponding to different process requirements can be divided, including injection molding molds, extrusion molding molds, suction molds, and high-expanded polystyrene molding molds.
Plastic injection (plastic) mould
It is mainly used in the production of thermoplastic plastic products. The corresponding processing equipment of plastic injection mold is plastic injection molding machine. The plastic is first heated and melted in the heating barrel at the bottom of the injection machine, and then the screw of the injection machine. Or push the plunger, enter the mold cavity through the injection system of the injection nozzle and mold, plastic cooling hardened, demoulding products. Its structure is usually composed of molding parts, casting system, guide parts, ejection mechanism, temperature control system, exhaust system, and supporting parts. Manufacturing materials usually use plastic mold steel modules, commonly used materials are mainly carbon structural steel, carbon tool steel, alloy tool steel, high-speed steel and so on. The injection molding processing method is generally only applicable to the production of hot plastic products. The plastic products produced by the injection molding process are very extensive. From the daily necessities of life to all kinds of complicated machinery, electrical appliances and vehicle parts are all molded by injection molding. It is the most widely used processing method in the production of plastic products.
