它主要是热塑性塑料件产品生产中应用最为普遍的一种成型模具，塑料注射模具对应的加工设备是塑料注射成型机，塑料首先在注射机底加热料筒内受热熔融，然后在注射机的螺杆或柱塞推动下，经注射机喷嘴和模具的浇注系统进入模具型腔，塑料冷却硬化成型，脱模得到制品。其结构通常由成型部件、浇注系统、导向部件、推出机构、调温系统、排气系统、支撑部件等部分组成。制造材料通常采用塑料模具钢模块，常用的材质主要为碳素结构钢、碳素工具钢、合金工具钢，高速钢等。注射成型加工方式通常只适用于热塑料品的制品生产，用注射成型工艺生产的塑料制品十分广泛，从生活日用品到各类复杂的机械，电器、交通工具零件等都是用注射模具成型的，它是塑料制品生产中应用最广的一种加工方法。

It is mainly a kind of moulding mould which is widely used in the production of thermoplastic parts. The processing equipment of plastic injection moulds is plastic injection moulding machine. Plastics are first www.biansongqi.org.cnwww.shidiaopailou.com.cnwww.shilangan.net.cnwww.shidiaoshizi.net.cn

www.shidiaopaifang.cnwww.shidiaoniu.cnheated and melted in the bottom heating barrel of injection moulds. Then, driven by the screw or plunger of injection moulds, the injection moulds are cooled and hardened by the injection nozzle and the injection moulds pouring system. The product is obtained by demoulding. Its structure is usually composed of forming parts, pouring system, guiding parts, pushing mechanism, temperature control system, exhaust system, supporting parts and so on. Plastic die steel module is usually used for manufacturing materials. The common materials are carbon structural steel, carbon tool steel, alloy tool steel, high-speed steel and so on. Injection moulding process is usually only suitable for the production of thermoplastic products. Plastic products produced by injection moulding process are very extensive. From daily necessities to all kinds of complicated machinery, electrical appliances and transportation parts are all moulded by injection moulds. It is the most widely used processing method in the production of plastic products.
