毕业论文《通用绕线架注塑模具设计》.doc

内容提要 本设计主要讲述了以软聚氯乙烯（SPVC）为材料的线圈高骨架注塑模具的设计过程。 此模具在设计时，充分考虑了生产批量、以提高生产效率、降低生产成本为主要宗旨。 本产品为电动机绕线圈，形状规则，内空心，侧有凹槽，其要求它具有耐光，耐化学腐蚀、耐磨。结合这些要求，材料选择软聚氯乙烯。根据计算出的体积与质量选择SZ-100-60型号的注塑机注塑。由于塑件内空心，侧有凹槽要求模具必需采用斜导柱侧抽芯机构分型。经过比较，采用斜导柱在定模，哈夫块（斜滑块）在动模的结构 。整体斜楔定位，斜导柱侧抽芯分型，推板推出工件的工作原理。 设计中对主要零件一一的进行了设计。文中插入了非标准零件图，以及模具结构图。 Contents brief summary Is it tell taking soft polyvinyl chloride (SPVC ) as material coil high skeleton mould plastics idea course of mould mainly to design originally. This mould is in the design, fully consider production lot , regard improving production efficiency , reducing the production cost as the main aim. This product winds the coil for the motor, form rule, hollow inside, the side has grooves , it requires it is able to bear all, able to bear chemistry and corroded, wear-resisting . Combine these require material choose the soft polyvinyl chloride. Choose the moulding plastics machine of SZ-100-60 type to mould plastics according to the volume and quality calculated out. Mould piece hollow , side have groove demand mould must adopt oblique to lead post side release the core organization dividing into type. Through compare, adopt oblique to lead post make mould , Haff piece (oblique to slip yuan ) Move the structure of the mould . Whole oblique wedge make a reservation, oblique to lead post side release core person who divide , push board put out operation principle of work piece. To the designing one by one of major part in the design. Have inserted the non-standard part picture, and mould structure chart in the article. 目 录 内容摘要……………………………………………………………… I Contents brief summary…………………………………………… II 前言…………………………………………………………………… 1 第1章 塑件分析………………………………………………… 2 第1.1节 塑件工艺性能分析……………………………………… 2 第1.2节 塑件批量………………………………………………… 2 第1.3节 塑件批量体量和质量…………………………………… 3 第2章 注塑机的选择…………………………………………… 4 第2.1节 注塑机的概述…………………………………………… 4 第2.2节 选择注塑机……………………………………………… 6 第3章 模具设计的有关计算…………………………………… 6 第3.1节 成型零件工作尺寸的计算……………………………… 6 第3.2节 成型腔壁厚的计算
