齿轮箱外覆盖件造型设计及注塑模具设计

摘     要

模具生产技术水平的高低不仅是衡量一个国家产品制造水平高低的重要标志，而且在很大程度上决定着这个国家的产品质量、效益及新产品开发能力。模具生产将继续朝着精细化、自动化的方向发展，模具企业继续向着技术集成化、设备精良化方向发展。

为了适应企业发展和市场竞争的需要，结合毕业实习的具体内容，进行齿轮箱外覆盖件的造型及注塑模具设计。首先从阐述模具行业的背景入手，给出对应齿轮箱覆外盖件模具框架结构设计，在此基础上，对相应的模块进行具体设计，从而给出对应的齿轮箱外覆盖件模具模型。结合Pro/E三维造型软件，给出了具体的模具设计零件和装配结果,利用Emx加载模架。对于初次涉及模具的我在此主要是精细化方面小配件模具的研究。为以后进入模具设计的高精度、高复杂程度、高一致性、高生产力和低消耗做好准备。

Automotive plastic mold design

 

Abstract

    Die level of production technology is not only a measure of a country's level of product manufacturers an important symbol, but also to a large extent determine the country's product quality, efficiency and new product development capability. Mold will continue to move production of refinement, the direction of automation, tooling technology integration business continues to improve and develop in the direction of well-equipped.

    In order to adapt to enterprise development and the needs of market competition, combined with the specific content of graduate training for automotive plastic mold design structure. First of all, the mold from the start with the background of the industry, given the structure of the corresponding pieces of automotive plastic mold the framework of structural design, on this basis, the corresponding gating system, module-oriented institutions such as the specific design, which gives the structure of the corresponding pieces of automotive plastics Die model. Pro/E combined three-dimensional modeling software, are given specific parts of the mold design and assembly of the results, then build the construction by EMX. Involved for the first time I die in this area is mainly refined small car parts research tool. Into the molding for future high-precision die design, high-complexity, high consistency, high productivity and low ready.
