塑料注射（塑）模具
Plastic injection mold
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 molding mold which is widely used in the production of thermoplastic parts. The processing equipment corresponding to the plastic injection mold is the plastic injection molding machine. First, the plastic is heated and melted in the heating barrel at the bottom of the injection machine, and then, driven by the screw or plunger of the injection machine, enters through the nozzle of the injection machine and the pouring system of the mold Mold cavity, plastic cooling hardening molding, demoulding products. Its structure is usually composed of forming parts, pouring system, guiding parts, pushing mechanism, temperature regulating system, exhaust system, supporting parts, etc. Plastic mold steel module is usually used as the manufacturing material, and the commonly used materials are mainly carbon structural steel, carbon tool steel, alloy tool steel, high-speed steel, etc. Injection molding process is usually only applicable to the production of thermoplastics products. The plastic products produced by injection molding process are very extensive. From daily necessities to all kinds of complex machinery, electrical appliances, vehicle parts, etc. are molded by injection mold. It is the most widely used processing method in the production of plastic products.
