The plastic injection mold is mainly a molding mold which is most commonly used in the production of thermoplastic plastic parts. The processing equipment corresponding to the plastic injection mold is a plastic injection molding machine. The plastic is first heated and melted in the heating barrel of the injection machine, and then in the injection machine. Pushed by the screw or plunger, the injection system of the nozzle of the injection machine and the mold enters the mold cavity, and the plastic is cooled and hardened to form a product.
The structure is usually composed of a molded part, a pouring system, a guiding part, a pushing mechanism, a temperature regulating system, an exhaust system, a supporting part and the like. The manufacturing materials usually use plastic mold steel modules. The 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 usually only applicable to the production of thermoplastic products. The plastic products produced by the injection molding process are very wide, from daily necessities to various complicated machinery, electrical appliances, vehicle parts, etc., which are molded by injection molding. It is the most widely used processing method in the production of plastic products.
