1、 1 风扇叶片风扇叶片注射注射模具设计模具设计 摘要摘要：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；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 EMX 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，

2、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 EMX 的学习，可以将繁杂的设计工作自动 化，从而有效的提高工作效率。 关键词关键词：塑料模具；参数化；镶件；分型面 2 The plastic injection model design of Fan blades The major: Machine design Manufacturing and Automation Author: Liu shuntao Tutor: Du xibo Abstract: plastic industry is in the world grows now one of quickest

3、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 design introduced the injection takes shape the basic principle,specia

4、lly 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

5、 the design process,and has given the explanation to the mold intensity request; Finally introduced now in the world the most popular three dimensional CAD/CAM system standard software PRO/Engineers EMX module,and led the wrap to the guide pillar to carry on the parameterization design. Through this

6、 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 EMX study,may establish complicated design automation,thus effective enhancement working efficiency. Key word: The plastic mold; the parameterization; inlays; divides the profile 3 前 言. 1 1 模具简介 2 1.1 模具工业在国民经济中的地位 2 1.2 各种模具的分类和占有量 . 3 1.3 我国模具工业的现状 4 1.4 世界五大塑料生产国的产能状况. 5 1.5 我国模具技术的现状及发展趋势. 7 2 注射模可行性分析
