摘要
在现在这个高速发展日新月异的的社会，电话，已是人们沟通必不可少的通讯设施，就无线电话而言，人们的消费水平提高后，开始了对精神上的满足提出了要求，要求其既要符合人们的要求，也要美观，给人赏心悦目的感觉，所以设计者就人们提出的要求和意见，设计符合大众的消费，这样才会有共同的利益。
无线电话的材料主要来自塑料，即大部分的零件都是以注塑模而制造的，特别是无线电话的后壳，因此，注塑模在电子电话行业中显得尤为重要。
这几年，模具的发展十分迅速，高效率、自动化、大型、微型、精密、高寿命的模具在整个模具产量中所占的比例越来越大，而注塑模也是其中比例占的很大，从模具设计和制造角度来看，注塑模具有能一次成型结构复杂、尺寸精确、精度较高的产品。因此，适用于高效率、大批量生产制品的方式。
国内发展模具的年代比较短，为了能跟上国际社会的脚步，必须借鉴国外的技术，加以改进，能运用到国内的需求发展，同时，也要自主创新，走自己发展的道路，能符合国内经济需求的道路。
注射成型是热塑性塑料成型的主要方法之一，可以一次成型形状复杂的精密塑件。本设计是无线电话上壳塑料模具的设计，对零件结构进行了工艺分析，采用ABS作为塑件的材料。采用单分型面，根据模具的型腔数目以及最大注塑量、注射压力、锁模力、模具的安装尺寸等因素选择了注射机，选择成型零部件的尺寸；采用扇形浇口；利用直导柱导向，斜滑顶杆顶料,斜滑顶杆侧抽，同时完成侧抽和顶出完成脱模，并对模具的材料进行了选择，如此设计出的结构可确保模具工作运行可靠。对模具结构与注射机的匹配进行了校核。用UG绘制出模具三维图形及AutoCAD绘制了一套模具装配图和零件图，最后利用UG对型腔进行了加工仿真，制定了符合要求的数控加工工艺过程。

increase, demand began to mental satisfaction, ask its should accord with the requirement of people already, also want to beautiful, give a person feel cheerful and pleasing to the eye, so the designer put forward opinions and demands of the people, the design conforms to the mass consumer, such ability can have a common interest.
Wireless telephone materials mainly from plastic, that is, most of the parts are manufactured in injection mold, especially after wireless phone shell, therefore, injection mold is particularly important in the electronic telephone industry.
In recent years, the development of the mould is very rapid, high efficiency, automation, large, miniature, high precision, the life of the mold in the mold production and the proportion of more and more big, and is also accounted for a large proportion of injection moulds, from the Angle of mold design and manufacturing, injection molding has to a molding complex structure, precise size, high precision products. Therefore, suitable for high efficiency and mass production products.
S domestic development mold is shorter, in order to keep up with the pace of the international community must draw lessons from foreign technology, improved, can apply to the development of domestic demand, at the same time, also want to independent innovation, following the path of their own development, can meet the demand of the domestic economy.
Injection molding is one of the key ways of thermoplasticity plastic molding which can mold precise plastic part with complex shape. The design is a plastic mould design of the back over of mobile, which analysis part structural with ABS as the material of plastic part. The design adopt single parting surface, choose injection machine, the dimension of molding parts according to the factors of the number of molding die cavity and the maximum injection, injection pressure, locking force and so on, adopt fan gate, use straight guide pillar guiding, slanting ejector to eject materials and side core pulling to side core pulling and ejecting, and choose the materials of mold, which can ensure the reliability of molding. This paper check the matching of the structure of molding and injection machine, draw the three dimension of molding with UG a set of molding assembly drawing and part drawing with AutoCAD, utilize UG to simulate machining of mould core and mould cavity and make qualified working process of numerical control.
