摘 要
模具被誉为工业之母,模具制造技术高低直接体现出一个国家的综合经济实力。注塑模具是模具行业中应用很广泛的一种模具,主要用于塑料产品的成型。本文为一个开关盒壳件设计了一副单分型面的注塑模具。首先分析了塑件的结构工艺性,结合厂方的要求,选择了一模两腔的型腔布局,且确定了分型面的位置,并选择了注射成型机。然后在完成了模具各组成部分的设计计算后,利用UG 5.0完成了整副模具的三维CAD。最后绘制了模具装配图和主要零件的零件图。总体而言,设计过程科学,模具结构简单,各机构运行可靠。

Abstract
Mold is called “ the mother of industry”, so the mold manufacturing technology reflects general economic power of a country directly. Injection mold is one kind of most used mold, which is mainly used for plastics molding. A set of two-plate injection mold is designed for a swith cover in this dissertation. Firstly analysis of the process ability of product structure and bicavitary layout and the position of the parting plane is determined, according to the product manufacturer’s demand. Then selection of the injection machine is made. Moreover, 3D design of the injection mold is finished in UG 5.0, after the calculation of the mold systems, such as gating system, ejecting system, etc. At last, some drawing of the important parts in the mold is completed. In general, the calculation of the mold design is right, and the mold structure is simple and liable.
