摘 要 关键词：；；； Abstract Printer gear were widely used in industrial production. In order to adapt to the users of the mold manufacturing which become high precision, short delivery time, low-cost requirements, the mold industry is widely used digital manufacturing technology to accelerate the advancement of technology. To short the mold manufacturing cycle and reduce the cost of the mold, CAD / CAM technology must be used. 牋牋 Designing mold , develop printer gear master injection mold design and molding process of the products of choice; the general gear mold design capability, quality analysis and process improvement, ability to improve the design of injection mold structure; commonly used software, and a combination of the actual design of the same.牋牋The mold design process analysis, process characteristics of the printer gear, and PA66 material molding process characteristics, different molding program and compared in the mold design process, to take the best molding program, at the same time detailed mold structure and calculation. Mold can be achieved through the entire design process show that the requirements for the processing of the plastic parts. The main task is to design under the title injection mold design of plastic gears. An injection mold is designed to produce the gear plastic products to automate increase production. Finally, the molded part of the mold process analysis equipment check, and also describes the working principle of the mold, the mold equipment also made a brief introduction. Key words: Mold Design; Printer gear; Injection Molding 目 录 摘 要 II Abstract III 目 录 IV 1 绪 论 1 1.1 本课题的研究内容和意义 1 1.2 国内外塑料成型模具发展概况 1 1.3本课题应达到的要求 3 1.4 本课题应达到的要求 3 2 打印机齿轮成型工艺性分析 4 2.1 打印机齿轮分析 4 2.2 注射成型过程及工艺参数 5 2.3 PA66的性能分析 6 3模具结构形式的拟定 7 3.1 分型面位置的确定 7 3.2 确定型腔数量及排列方式 8 3.3 模具结构形式的确定 8 4 注射机的选用 10 4.1 所需注射量的计算 10 4.2 注射机型号的选定 10 4.3 型腔数量及注射机有关工艺参数的校核 11 4.3.1 型腔数量的校核 11 4.3.2 注射机工艺参数的校核 12 4.3.3 安装尺寸校核 12 4.4 开模行程和推出机构的校核 13 4.4.1 开模行程校核 13 4.4.
