摘 要

 塑料工业是当今世界上增长最快的工业门类之一，而注塑模具是其中发展较快的种类，因此，研究注塑模具对了解塑料产品的生产过程和提高产品质量有很大意义。本文讨论了应用Pro/E微机辅助设计圆盒盖注塑模具的设计方法。介绍了注射成型的基本原理特别是单分型面注射模具的结构与工作原理，对注塑产品提出了基本的设计原则；制品采用材料为低密度ABS。注射成型是热塑性塑料成型的主要方法之一，可以一次成型形状复杂的精密塑件。本设计进行了圆盒盖的注塑模设计，对零件结构进行了工艺分析。确定了分型面、浇注系统等，选择了注射机，计算了成型零部件的尺寸。采用侧浇口。利用直导柱导向，推杆顶料,顶板完成脱模。如此设计出的结构可确保模具工作运用可靠。最后对模具结构与注射机的匹配进行了校核。并用AUTOCAD和Pro/E绘制了一套模具装配图和零件图。最后介绍了当今世界上最为普及的三维CAD/CAM系统标准软件PRO/ENGNEER的PROGRAM模块，对导柱和导套进行了参数化设计。通过本设计，可以对注塑模具有一个初步的认识，注意到设计中的某些细节问题，了解模具结构及工作原理；通过对PROGRAM的学习，可以建立较简单零件的零件库，从而有效的提高工作效率。

ABSTRACT

Plastic industry is in the world grows now one of quickest industry classes, but casts the mold is development quick type, therefore, the research casts the mold to understand the plastic product the production process and improves the product quality to have the very big significance.
This paper discusses the designing of the mould for producing the plastic case of can cover with Pro/E; This design introduced the injection takes shape the basic principle, specially single is divided the profile to inject the mold the structure and the principle of work, to cast the product to propose the basic principle of design; Material is the ABS. Liquid plastic molding injection molding is one of the main ways to shape a shaped complex precision mold pieces. The design of the can cover cast mould design, structural parts for the craft analysis. Identified sub-type face, such as the old system, chose injection machine, the size of a shape parts. Use side runner. Using straight-pillar orientation, push rod top expected, leading to complete drawing of patterns and winning ways of pumping core materials and components for the choice. This structure ensures that instrument design work using reliable. Injection molding machine to the final structure and the degree of machine . And use AUTOCAD , Pro/E mapping components assembly, and parts of a map. Finally introduced now in the world the most popular three dimensional CAD/CAM system standard software PRO/ENGNEER PROGRAM module, and led the wrap to the guide pillar to carry on the parameterizations design .Through this design, may to cast the mold to have a preliminary understanding, notes in the design certain detail question, understands the mold structure and the principle of work; Through to the PROGRAM study, may establish the simple components the components storehouse, thus effective enhancement working efficiency.
