模具是一种生产塑料制品的工具
1、近年来，随着塑料工业的飞速发展和通用与工程塑料在强度和精度等方面的不断提高，塑料制品的应用范围也在不断扩大，如：家用电器、仪器仪表，建筑器材，汽车工业、日用五金等众多领域，塑料制品所占的比例正迅猛增加。一个设计合理的塑料件往往能代替多个传统金属件。工业产品和日用产品塑料化的趋势不断上升。
1. In recent years, with the rapid development of plastic industry and the continuous improvement of strength and precision of general and engineering plastics, the application scope of plastic products is also expanding, such as: household appliances, instruments, building equipment, automobile industry, daily hardware and other fields, the proportion of plastic products is increasing rapidly. A well-designed plastic part can often replace multiple traditional metal parts. The plastic trend of industrial products and daily-use products is on the rise.
2、模具的一般定义：在工业生产中，用各种压力机和装在压力机上的专用工具，通过压力把金属或非金属材料制出所需形状的零件或制品，这种专用工具统称为模具。
2. General definition of mold: in industrial production, metal or non-metallic materials are made into parts or products with required shape by using various presses and special tools installed on the press. This special tool is collectively referred to as mold.
3、注塑过程说明：模具是一种生产塑料制品的工具。它由几组零件部分构成，这个组合内有成型模腔。注塑时，模具装夹在注塑机上，熔融塑料被注入成型模腔内，并在腔内冷却定型，然后上下模分开，经由顶出系统将制品从模腔顶出离开模具，最后模具再闭合进行下一次注塑，整个注塑过程是循环进行的。
3. Injection molding process description: mold is a tool to produce plastic products. It is composed of several groups of parts, and the combination has a forming cavity. During injection molding, the mold is clamped on the injection molding machine, and the molten plastic is injected into the injection mold cavity, and cooled and shaped in the cavity. Then, the upper and lower molds are separated, and the products are ejected from the mold cavity through the ejection system. Finally, the mold is closed for the next injection. The whole injection process is cyclic.
