魅族手机外壳后盖的注射模具设计
摘要
近年来，中国的手机行业对模具行业造成了很大的影响，特别是对塑料模具制作越来越高的要求，在2014年的快速发展后，整个模具塑料模具行业中所占的比重已上升到45％左右，据专家估计，在未来几年，中国塑料模具行业将继续保持高速超过12％的年均增长速度发展。国内市场上的塑料模具中注塑模具需求量最大，其中重点注重于塑料模具的发展。
注射成型是塑料成型的一种重要方法，他主要适用于热塑型塑料的成型，可以一次成型形状复杂的很精密塑件。本课题就是将手机的外壳作为设计的模型，将注射模具的相关知识作为依据，讲述塑料注射模具设计的过程。
本设计对手机外壳进行的注塑模设计，利用UG软件来对塑件进行了实体的建模，对塑件的结构进行了工艺分析。明确了设计思路，确定了注射成型工艺过程并对各个具体部分进行了详细的计算和校核。如此设计出的结构保证了与其他部件的配合，确保模具工作运用可靠。再继续用UG对其进行制图和CAM加工。
本课题通过对手机外壳后盖的注射模具设计，巩固和深化了所学知识，取得了满意的成绩，达到了之前期望的设计意图。

Abstract
In recentyears, China's mobile phone industry has had a great impact on the mold industry, especially on the increasingly high demand for plastic mold manufacturing. With the rapid development in 2014, the proportion of thewhole mold and mold industry has risen to about 45%. According to experts'estimation, China's plastic mold industrywill be in the next fewyears. Wewill continue to grow at an annual rate of over 12%. In the domestic market, the demand of injection mold is the largest, and the emphasis is on the development of plastic mold.
Injection molding is an important method of plastic molding. It is mainly suitable for thermoplastic molding. It can be used to formvery precise plastic partswith complex shapes at one time. This topic is to take the shell of the mobile phone as the design model, and the injection mold knowledge as the basis to describe the process of plastic injection mold design.
This design carries on the injection mold design to the mobile phone shell, carries on the solid modeling to the plastic part by UG software, carries on the technological analysis to the plastic part structure. The design idea is clarified, the injection molding process is determined, and the detailed calculation and check of each specific part are carried out. The structure thus designed ensures the cooperationwith other components to ensure reliable application of the die. Then continue to use UG to map and CAM processing.
Through the injection mold design of the back cover of the mobile phone shell, this subject solidifies and deepens the knowledge learned, and achieves satisfactory results, and achieves the desired design intention.
