摘要
设计的内容主要是对塑料茶杯的注塑模具设计。本次模具设计一共有9个步骤：对塑件进行分析；选择适合的注塑设备；计算成型的零件尺寸；选择适合的分型面；设计浇注系统；设计导向机构；设计脱模结构；设计排气和冷却系统；最后是选择适合的模架。在这次模具设计中，主要运用UG和CAD这两种制图和分析软件，运用UG进行计算塑件体积，选取适合的注塑机，对于动定模、浇口、流道、冷料穴、定位圈的设计也需要用到UG。运用CAD来制作二维和三维的模型，比如标准模架、导向机构、脱模机构、排气系统及冷却系统的设计和动定模底座、动定模板、推杆、推杆固定板、浇口导套和支撑板零件的图纸设计，合理运用这两个软件，进行参数校核，对于不合理的数据加以进一步修改。最后通过查阅相关资料进行设计说明书的撰写，以求达到严谨工作标准。

Abstract

 The content of the graduation project is mainly about the injection mold design of plastic cups. There are 9 steps in this mold design: analysis of plastic parts, selection of suitable injection molding equipment, calculation of formed part dimensions, selection of a suitable parting surface, design of a casting system, design of a guide mechanism, design of a mold release structure, and design of a row Gas and cooling system; the last is to choose the right mold base. In this mold design, the two drawing and analysis softwares, UG and CAD, are mainly used to calculate the volume of plastic parts using UG, and the appropriate injection molding machine is selected. For the dynamic mold, gate, runner, cold material point, positioning The circle design also needs to use UG. Use CAD to create 2D and 3D models, such as standard formwork, guides, ejection mechanism, exhaust system and cooling system design and dynamic mold base, dynamic template, push rod, push rod fixing plate, pouring The drawing design of the guide bush and support plate parts, rational use of these two softwares, parameter checking, and further modification of unreasonable data. Finally, the design specification was written by consulting related materials in order to achieve strict working standards.
