电器件后盖注塑模具设计和实现 机械制造及其自动化专业VIP专享

摘要本文通过查找文献等途径，针对电器件后盖注塑模具设计的总体要求，先对相应的塑件成型工艺、加工精度要求进行了分析；并在此基础上，通过对注塑机进行选择和校核，得出海天 80CX 型号的注塑机能够完全满足本文的需求；然后又对注塑模具进行了合理的结构设计以及材料的选择；最后通过三维建模软件进行装配图和零件图的绘制，并采用说明书和计算分析的形式完成了模具设计的论文。关键词：成型工艺；UG 三维建模；模具设计；注塑机；模具材料AbstractAccording to the general requirements for injection mold design of electronic component covering. Firstly, the plastic molding process and the machining precision is analyzed; Secondly, the injection molding machine has been selected and checked, results show that Haitian 80CX can fully meet the demand; Then the reasonable structure design and material selection of the injection mold are discussed. Finally, the assembly and detail drawings have been completed using 3D modeling software, and with a detail report and much of calculations, the graduation thesis is done.Key Word：Molding process；UG 3D modeling；Mould design；Injection molding machine；Mold material目 录第 1 章 绪述................................................1第 2 章 塑件成型工艺性分析..................................22.1 塑件分析.....................................................22.2 材料的选择...................................................22.3 成型结构设计分析.............................................2第 3 章 注塑机选择和校核....................................43.1 选择模具注塑机...............................................43.1.1 塑件体积及质量估算.....................................43.1.2 凝料体积的初步估算.....................................43.1.3 注塑机的初步选择........................................43.2 注塑机工艺参数校核...........................................53.2.1 最大注射量校核.........................................53.2.2 注射压力及锁模力的校...
