本科毕业设计（论文） 题目 复印件送纸机构零件的模具设计 学 院 机械工程学院 年 级 2008级 专 业 机械工程及自动化 班 级 0707082 学 号 070708211 学生姓名 杨 炎 指导教师 章泳健 职 称 副教授 论文提交日期 2012-5-6  摘要 本文主要介绍了复印机送纸机构注射模具的设计过程，首先是通过现实对送纸机构的观察，根据二维零件图创建三维模型，分析产品的结构工艺性，尺寸精度等，进而初选注射机型号。其次，对模具的结构分析和设计，包括型腔数目的确定、主流道和分流道的设计、分型面的选取、浇口的设计、型腔型芯的结构形式的确定等等。本文重点介绍了模具工作尺寸的计算和固定形式，分型面的结构，温度调节系统，脱模顶出机构，斜滑块侧向分型与抽芯机构，复位机构等主要零部件的设计过程，并对注射机的注射量、锁模力、开模行程等工艺参数进行了校核。本模具的主要结构是采用两板式模具，侧浇口注射，斜滑块外抽芯机构，应用推杆顶出塑件，滑块推杆进行复位。本模具应用了自动化的生产模式，对产品的生产效率的提高有着非常重要的作用。 关键词：送纸机构 注射模具 斜滑块抽芯 /thread-8307-1-1.html 现成设计购买注意事项 /thread-8308-1-1.html 定做设计流程以及注意 Abstract The paper advance mechanism injection mold design process was mainly introduced in this article. First, though the observations of the frig , the paper advance mechanism was designed. Draw three-dimensional view of the structure of products. Anoalyzed the technological characteristics, the selection of size tolerance and of the paper advance mechanism. Second, analysised and designed the structure of the mold. include the determination of the number of cavity, the mainstream, and shunt the design, select the type of surface, the gate design, cavity of the core structure of the set, and so on. This article focuses on the work of die size and the calculation of fixed form, the sub-surface structure, temperature-conditioning systems, Stripping out the top institutions, oblique lateral slider type and core pulling bodies, institutions and other major components reset the design process. Finally, checked the injection of injection machine, the clamping force, open-trip process parameters. Introduced the die installation and test mode. The main structure of the mold is used three plate die, the injection point gate, ramp slider, core pulling bodies from the top of putting plastic parts, a reduction-reduction. The mold is used in automatic mode of productions; the product of the efficiency of the production has a very importan
