设计简介
摘 要
近年来在我国工业化快速推进的同时，在国民经济中占有重要地位的模具工业也得到了迅速发展。统计显示，1996至2001年，我国模具制造业的产值年均增长14%到15%。2001年我国模具总产值就已突破300多亿元人民币，排名跃居世界第四位。虽然近几年来，我国模具工业的技术水平已取得了很大的进步，但总体上与工业发达的国家相比仍有较大的差距。此次的设计任务即显示器后壳模具设计，首先我使用模具设计软件建立产品的2D、3D模型，并对其模具设计！再用所学的注塑模设计，以及机械设计等方面的知识，利用模具设计软件对塑件进行了实体造型，对塑件结构进行了工艺分析。然后明确了设计思路，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。如此设计出的结构可确保模具工作运用可靠，保证了与其他部件的配合。最后用AUTOCAD绘制了一套模具装配图和零件图。
本课题通过对显示器后壳底板的注射模具设计，巩固和深化了所学知识，取得了比较满意的效果，达到了预期的设计意图

ABSTRACT
At the same time, the rapid advance of industrialization in our country in recent years in the national economy occupies an important position in the mold industry has got rapid development. Statistics show that from 1996 to 2001, our country mold manufacturing output grew by an average of 14% to 15%. Mould of 2001, China's total output value has reached more than 300 300 yuan, ranked as the fourth in the world. Although in recent years, mould industry technology level in China has made great progress, but on the whole, compared with developed countries still have larger gap. After the design tasks which display shell mold design, first of all, I use mold design software, 2 d and 3 d model of building products, and the mold design! Then use what they have learned the injection mold design, and mechanical design knowledge, the use of plastic parts mold design software entity modelling, has carried on the structure of plastic parts process analysis. Then clear the design ideas, to determine the injection molding process and to each specific parts of detailed calculation and checking. Such a structure are designed, which can ensure the mold work using reliable, to ensure the cooperation with other parts. Finally using AUTOCAD drawing a set of mold assembly drawing and part drawing.
This topic through to the display after the shell plate of injection mold design, consolidate and deepen the knowledge, and achieved satisfactory results, achieved the desired design intent
Keywords: Injection mold design Entity modeling Process analysis The mold design
