设计简介
摘 要
我国塑料模具工业从起步到现在，经历了半个世纪，有了很大发展，模具水平有了较大的提高。由于模具生产产品具有精度高，复杂性高，一致性好，生产效率高消耗低等优点。所以现代工业中将会起到更大的作用，得到更多的应用。我的塑料发展至今，已能生产精度高达2微米的精密，多工位级进模，工位数最多已达160个，寿命1~2亿次。
模具时现代工业发展的基础，许多产业的发展都离不开模具行业的支持。用模具生产制造所表现出来的的高精度，高复杂程度，高一致性，高生产率和低消耗，是其他加工制造方法所不能比拟的。在模具工业的总产值中塑料模具约占33%。不同的塑料成型方法使得模具原理和结构不通。按照成型方法的不通，塑料模具分为：注塑模具，压塑模具，吹塑模具等。注塑模具主要用于热塑性塑料制品的成型中占有很大比重。现代工业中，消费品外壳的色彩，手感，和精度，厚度等提出了新要求。塑料外壳设计成为重要的一环。设计合理的注塑模具将得到越来越多的应用。
现代注塑模具的设计方法目前为了应付当前多样化的要求，缩短产品只在周期以缺德最佳的竞争优势，模具设计中都引用了CAD/CAE计算机一体化制造技术，以提高产品质量，降低成本，增加竞争力，一般而言，一件完整理想的工业产品，其制造流程为现有原创型的概念设计出原件，配合计算机辅助工程分析技术，再依据分析结果修改测试，最后再依据设计图经由计算机辅助制造，进行产品自动化生产在模具设计生产，以上整个过程均在计算机上进行。
在模具设计生产过程中，应用Pro/ENGINEER软件进行模具结构设计-模具型腔-型芯二维设计-工艺准备-模具型腔，型芯设计三维造型等。
随着计算机技术和网络技术取得了突破性的成就，模具设计越来越多地使用CAD/CAM技术。在产品生产之前，使用这些新技术来进行模具的设计和改善，是现代设计必然趋势在现实生活里，手机已经成为人们的一个生活必须品，现代的手机已经不再仅仅是一个工具同时一时装饰品，所以做出的不管是手机机身还是手机壳都需要美观大方，因此加工工艺就显得非常重要。所以在对手机壳的模具设计时不仅要考虑成型，还需要考虑成型后的美观。因此在模具的设计过程中多方兼顾。

Abstract
Plastic mold industry in China from the beginning to now, has experienced half a century, has made great development, mould level has greatly improved. Because the mold production product has high accuracy, high complexity, good consistency and high efficiency low consumption etc. So modern industry will play a greater role, get more applications. Precision plastic development up to now, I have been able to produce as much as 2 micron precision, multi-station progressive die, has reached the maximum number of stations in 160, life 1 ~ 200 million times.
Mould the basis for the development of modern industry, many industry's development cannot leave the mould industry support. With mold manufacturing of high precision, high complexity, high consistency, high productivity and low consumption, is can't be matched by other methods of processing and manufacturing. In the mold industry plastic mould accounted for about 33% of the total output. Different methods of plastic molding makes mold principle and structure. According to the forming method of impassability, plastic mold is divided into: injection mold, compression mold, blow molding mould, etc. In the injection mold is mainly used for thermoplastic plastics molding occupies a large proportion. In modern manufacturing, consumer goods shell color, feel, and precision, thickness, etc. Put forward new requirements. Plastic shell design become important one annulus. Reasonable design of injection mould will be applied more and more.
Modern design method of injection mould at present in order to cope with the current diversified requirements, shorten the product by the wicked the best competitive advantage, only in the cycle of mould design reference the CAD/CAE technology of computer integrated manufacturing, in order to improve the product quality, reduce cost, increase the competitiveness, in general, a complete ideal industrial products, the concept of the manufacturing process for existing original type original design, with computer aided engineering analysis techniques, according to the results of analysis, modifying test again, and then on the basis of design through computer aided manufacturing, automated production in the mold design production, more than the whole process are conducted on the computer.
In the mold design and production process, the application of Pro/ENGINEER software to design the mould structure - the mold - core of two-dimensional design process to prepare - mold cavity, core design three dimensional modeling, etc.
Along with the computer technology and network technology has achieved breakthrough and mold design are increasingly using CAD/CAM technology. Before production, the use of these new technologies for the design of the mould and improvement, is an inevitable trend in the modern design in real life, mobile phones have become a people living necessities, modern mobile phone is no longer just a tool for decoration at the same time, so the mobile body or following needs to be beautiful and easy, so the processing technology is very important. So when opponents casing mold design should not only consider the forming, also need to consider after molding. Therefore, in the mold design process to two or morethings.
