摘要本人毕业设计的题目为手机后壳注射模设计，本设计从塑料产品的材料品种、性能、用途、模具零件结构尺寸设计等各方面详细分析了本产品的注塑加工工艺性，由于零件较小，又需大批量生产，故采用“一模二腔”。在参照塑件的体积、重量等参数后选择了注塑成型设备，并对注塑机的相关主要参数进行校核。本次设计模架采用的是标准模架，其中各模板尺寸都是通过详细的计算分析后参照标准选取的。对于各重要部件都选用了相应的精度。对于模具的浇注系统、推出机构都进行了详细的计算设计。关键词座块盖；注塑模；工艺分析；模具设计2 Abstract Oneself graduation design of topic for piece cover of inject and model molding tool design, this design is from the material species, function, use, the structure size of the molding tool spare parts design etc. everyone's noodles was detailed analysis note of this product Su process a craft, because of spare parts smaller, again need large quantity produce, past adoption"one mold two chambers". the weight and so on in the main parameter computed result foundation has carried on the choice to the injection molding machine equipment, and to chose after the injection molding machine to carry on the essential examination 。Through models a analysis regarding this, and carried on the intensity examination to the main spare part. Poured the system regarding the mold, promotes the organization has all carried on the detailed computation design.Sprinkled to note system and released organization to all carry on to the molding tool detailed of calculation design.At main to the physical volume, weight...etc. Keyword Piece cover;Note a Su mold;Craft analysis;Molding tool design 3 目录摘要、关键词 ,,,,,,,,,,,,,,,,,,,,,,,,,,, 2 Abstrac Key word ,,,,,,,,,,,,,,,,,,,,,,,,, 3 目录,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, 4 1. 引言,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, 62. 工艺分析 ,,,,,,,,,,,,,,,,,,,,,,,,,,,, 6 2.1 分析材...
