PAGE 本科毕业论文 （20 届） Φ32塑料三通注射模具的设计 专业：机械设计制造及其自动化 PAGE 摘 要：本文介绍了注射模具的特点及发展趋势。模具开发周期包括模具设计、制造、装配与试模等阶段。缩短设计周期并提高设计质量是缩短整个模具开发周期的关键之一。大量实践表明，模块化设计能有效减少产品设计时间并提高设计质量。因此本文探索在模具设计中运用模块化设计方法。叙述了三通管注射模具设计与计算的详细过程，介绍了该塑件成型工艺、注射模具的结构特点与工作过程, 阐述了在有斜滑块抽芯的注射模设计中应注意的事项。 关键词：三通管；注射模；周期；模块化 Φ32plastic three direction pipe inject mold Abstract：The characteristics and developments of injection mould will be introduced in this paper. The development of model includes designing, producing, assembling and examining steps etc. Shortening the period and enhancing the quality of design are the keys to shorten to entire development circle of model. Practices show that modular design is an effective way to reduce the time and enhance the quality of products .This paper mainly explores the method of applying the modular design in model design. The designing and calculating of injection mould of microphone will be stated in detail. The forming process of the product and the structure characteristics as well as working process of the injection mould will be introduced .The attention should be paid in the design of the injection mould for the part with lifters also will be stated. Key words: microphone; injection mould; Cycle; modular 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc292995187 1 引 言 1 HYPERLINK \l _Toc292995188 1.1选题背景、意义 1 HYPERLINK \l _Toc292995189 1.1.1选题背景： 1 HYPERLINK \l _Toc292995190 1.1.2选题意义： 1 HYPERLINK \l _Toc292995191 1.2论文研究的主要内容 1 HYPERLINK \l _Toc292995192 2 注塑成型的概述 2 HYPERLINK \l _Toc292995193 2.1注塑成型 2 HYPERLINK \l _Toc292995194 2.2注塑成型工艺过程 2 HYPERLINK \l _Toc292995195 3 塑件材料和注塑机的选择 3 HYPERLINK \l _Toc292995196 3.1塑件的分析 3 HYPERLINK \l _Toc292995197 3.2材料的分析和选用 4 HYPERLINK \l _Toc292995198 3.3注塑机的选择 5 HYPERLINK \l _Toc292995199 3.3.1注塑机工艺参数的校核 5 HYPERLINK \l _Toc292995200 3.3.2模具安装尺寸的校核 6 HYPERLINK \l _Toc292995201 3.3.3开模行程的校核 6 HYPERLINK \l _Toc292995202 4 模具的设计 6 HYPERLINK \l _Toc292995203 4.1分型面和排溢系统的设计 7 HYPERLINK \l _Toc292995204 4.2浇注系统的设计 7
