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,注射模技术的不断发展需要越来越多的工艺流程,注射成型过程中最重要的问题毫无疑问是注射模具的正确设计,因为成型车间对注射模具的影响很小,即便有,也是对机器的结构有影响的,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。
本设计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;详细介绍了冷流道注射模具浇注系统、温度调节系统和顶出系统的设计过程,并对模具强度要求做了说明;计算机辅助设计/计算机辅助制造是指为了提高生产率让计算机参与设计和制造产品的过程;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, The continuing development of injection mold technology demands more and more of the processes. The most important problem in the process of injection molding is undoubtedly the correct design of injection mold, because the molding shop has little influence,if any, on the construction of the machine. 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 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; Introduced in detail the cold flow channel injection evil spirit mold pours the system, the temperature control system and goes against the system the design process, and has given the explanation to the mold intensity request; Computer aided design/ computer aided manufacturing (CAD/CAM) refers to the integration of computer into the design and production process to improve productivity; Finally introduced now in the world the most popular three dimensional CAD/CAM system standard software PRO/ENGNEER' s PROGRAM module, and led the wrap to the guide pillar to carry on the parametrization 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.
Key word: The plastic mold; inlays; Side core pulling ;divides the profile
