罩盒注塑成型工艺及模具设计(机械加工工序卡)

罩盒注塑成型工艺及模具设计(机械加工工序卡)(含任务书,开题报告,中期检查表,毕业论文说明书7500字,cad图纸15张)
摘  要
塑件为小型件，精度要求不是很高，这就减少了设计的难度。通过对多个设计方案进行分析，最后决定采用方案如下：1.型腔个数为一模2腔。2.分型面设在最大截面处。 3.型腔的布局采用直线型。4.由于制件比较小，采用推杆顶出不是很理想，为合理起见采用推板和顶杆联合脱模.
由于时间紧，任务量较大，设计难免达到最合理。不过，此设计经过精确的计算，能够加工出合格制件。
关键词：塑料模、分型面、冷料穴、侧浇口。

Abstract
This plastics product’accuracy is not requested strictly.So it will reduce the difficulty of the design.Based on different design projects,I choose this project at last:(one),there are two mold cavities.(two) the parting surface is choosed on the biggest surface.(three) the distribution of the mold cavity is in a line.(four) for the product is so small that the ejector equipments of the mold is choose ejector plate.
As the time is short 、the mission is difficult。The design can not do very well.However,it is calculated accurately.So this mold can be used in actual.
Key words:Mold for plastics,parting surface,cold-slug well,edge gate.

设计目的及意义
     本设计题目为普通零件罩盒，但对做毕业设计的毕业生有一定的设计意义，它概括了盒盖塑料零件的设计要求、内容及方向。通过对该零件模具的设计，进一步加强了设计者注塑模设计的基础，为设计更复杂的注塑模具做好了铺垫和吸取了更深刻的经验。
