This design choice is currently the more popular selling electronic products - calculators, designed to mold plastic parts for the calculator to determine the shell . This paper is about the pulling side of the calculator shell injection mold design for a detailed description and explanation, through the calculator shell process analysis will eventually complete mold design is completed. A mold using a mold cavity, gate using point gate form, and provided with a cooling system, maximize productivity and improve the quality of plastic parts; paper also choose the injection molding machine, molding structure, the parting line selection parameters, data for detailed calculation and verification. The Pulling side of the computer case injection mold design, most parts using standard parts, molded parts using mosaic blocks, reducing mold manufacturing costs and production cycle, improve the market competitiveness; reference design process all kinds of data, use CAXAcad for drawing, reasonable and reliable design. Keywords: calculator shell; mold design; costs; efficiency 目 录 引言 1 1 绪论 2 1.1 注塑模具设计发展的概况 2 1.2塑料模具的特点 3 1.3 注塑模具设计的要求及程序 4 2 计算器外壳的设计及工艺分析 5 2.1 计算器外壳的设计 5 2.2 材料的选择 6 2.3 计算器外壳的工艺性分析 6 2.3.1 结构工艺性 6 2.3.2 塑件的批量生产 6 3 注塑机的选择及校核 7 3.1 初选注塑机 7 3.1.1 确定最大注塑量 7 3.1.2 确定模具温度及冷却方式 7 3.1.3 确定注塑成型的工艺参数 7
