摘 要
塑料制品在日常生活生产中应用非常广泛，塑料制品涉及到家电、手机、电子仪表、机电、汽车、电脑等行业。塑料制品由于它原料丰富、价格便宜、性能优良的特点。受到了人们的喜爱和好评。然而塑料成品质量的好坏与注射模具的设计、生产、加工工艺水平有着极其重大的关系。由此可见注塑模具在国民生产中的重要地位。设计和改良注塑模具以及模具的加工工艺是塑料产品生产需要长期研究的一个课题。
本次设计研究的小型立式空调控制版面外壳的模具设计及其模具加工工艺。首先根据外壳的使用要求和装配关系。确定空调控制版面外壳的尺寸大小和重要形状。设计出符合使用和生产的产品图。用UG设计确定产品图的尺寸建模成型。在产品设计完成后，通过UG分模、模架调用标准间的调用完成产品的模具设计。在通过产品体积、尺寸、产品材料的缩水系数，设计计算相关数据。最终确定模具的冷却系统、排气系统、开模行程等的设计和选择。
模具设计完成后开始考虑凹模凸模的生产和加工工艺的设计。在了解凹模凸模形状结构特点后，选择确定加工机床、确定加工工艺路线、完成加工工艺卡。最终用UG完成机床加工程序的编写并模拟加工完成。
由于以前接触模具设计比较少，在经过大量的模具设计模具加工程序等资料的学习后。对模具生产又有了更一步的了解和心得，更牢的掌握了自己的专业知识。

Abstract
The application in the production of plastic products in everyday life is very wide, plastic products related to home appliances, mobile phone, electronic instruments, electrical and mechanical, automobile, computer and other industries. Plastic products due to its abundant raw materials, cheap price, excellent performance characteristics. By the people's love and praise. However, the quality of plastic injection mold design and the quality of the finished product production, processing level has a significant relationship. This shows the important role in the national production of injection mold. Process design and improvement of injection mold and the mold is a long-term research subject of plastic products production needs.
Research on the design of small vertical air-conditioning control panel shell mould design and mould processing technology. Firstly, according to the use requirements of shell and assembly relation. Air conditioning control panel to determine the size and shape of the shell. Designed to meet the use and production of the product graph. To determine the size of graph modeling product design with UG. After the completion of product design, mold, mold the call through the UG standard calls to complete mold design products. In the product volume, size, material shrinkage coefficient, the design and calculation of relevant data. Finalize the design and selection of mold cooling system, exhaust system, mold opening stroke.
Design of mold design is completed to start production and processing technology of die punch. To understand the structural characteristics of the die punch shape machining tool, selection, determine the processing route, complete the process card. Finally using UG complete machining programming and simulation processing.
Due to previous exposure of mold design is less, after a lot of mold design and mold processing procedure of data after learning. The mold has a deeper understanding and experience, more firmly grasp their own professional knowledge.

1 课题背景意义
1.1 模具概况
随着我国市场经济发展现代化水平的提高，模具生产制造行业将会成逐渐成为了我的重要的工业组成部分，模具制造业是国民生产水平的基础行业，模具制造业的新衰将会直接影响到整个国工业的发展水平。模具制造水平将会对这个过整个国家的产品质量生产效率开发新产品的能力有特别大的影响。模具的生产技术也是现在国内先进尖端技术重点的应用的领域，现在的尖端的技术应用在模具行业将会大大的加强行业的发展水平，提高模具生产的水平和质量。现在模具行业技术科技的发展水平已经成为衡量一个国家的工业发展水平的重要标志。现在市场对模具的质量要求越来越高，一方面促进了模具的行业的发展，另一方面也对模具制造业提出了更高的要求。由于工业产品的发的生产，工业成品的种类数量不断的增多，所以对模具的要求数量也相应的增加，也相应的对模具行业提出了相应的要求，极短的生产周期将会是模具生产厂商的核心竞争力，在保证模具质量和生产要求的同时，短的生产周期将会提高国民工业的生产效率，而对于模具购买厂商极短的生产周期将会提高他们出新产品的效率，提高了他们的市场占有率。现在模具主要分为注射模具和冲压模具，注塑模具在大批量塑料产品的生产起到非常重要的作用，自动化生产在模具行业的应用将会大大的提高生产效率和产品品质。冲压模具主要用于金属类钣金件的冲压成型，在国民生产中也起到重大的作用，在汽车和家电行业钣金类的冲压模具，提高生产率的同时实现了产品多样化。冲压模具在汽车、家电制造行业的重要性可见一斑。
