台阶端盖注塑模具设计 学 生：XXX 指导老师：XXX （XXXXXXXXXXXXX 摘要：课题主要是针对仪表盖的模具设计,通过对塑件进行工艺的分析和比较,最终设计出一副注塑模。该课题从产品结构工艺性，具体模具结构出发，对模具的浇注系统、模具成型部分的结构、顶出系统、冷却系统、注塑机的选择及有关参数的校核、都有详细的设计，同时并简单的编制了模具的加工工艺。通过整个设计过程表明该模具能够达到此塑件所要求的加工工艺。根据题目设计的主要任务是底座注塑模具的设计。也就是设计一副注塑模具来生产底座塑件产品，以实现自动化提高产量。针对底座的具体结构，该模具是侧浇口的单分型面注射模具。其优点在于简化机构，使模具外形缩小，大大降低了模具的制造成本。通过模具设计表明该模具能达到底座的质量和加工工艺要求。 关键词：仪表盖；塑件;模具设计；注塑模具； Abstract: The topic mainly aims at the meter watch covers mold design, through to models to carry on the craft the analysis and the comparison, designs a note mold finally. This topic from the product mix technology capability, the concrete mold structure embarks, to molds gating system, the mold formation parts structure, goes against the system, the cooling system, injection molding machines choice and the related parameter examination, has the detailed design, simultaneously and simple establishment molds processing craft. Through the entire design process indicated that this mold can achieve this to model the processing craft which an institute requests. According to the topic designs primary mission is the foundation injection molds design. Is also designs an injection mold to produce the foundation to model a product, realizes the automation to raise the output. In view of foundations concrete structure, this mold is edge gate Shan Fen the profile injection mold. Its merit lies in the simplified organization, causes the mold contour to reduce, reduced molds production cost greatly. Through the mold design indicated that this mold can achieve foundations quality and the processing technological requirement. key word: Meter watch cover; Models; Mold design; Injection mold; 1 前言 塑料，由于具有一系列优异的物理力学性能、化学性能和易成形加工工艺性能而在轻工、农业、国防、航天航空、机械制造、建筑材料、交通运输、等部门及与 人们的日常生活密切相关的诸多方面都得到了非常广泛的应用。如果离开了塑料，那么难以想象我们生活、工作等环境会成为一个什么样子。也正是由于塑料具有许多特殊的性能，很快地从代替部分金属、木材、皮革等材料而发展成为国民经济中不可缺少的一类化工材料，并跻身与金属、纤维、硅酸盐三大传统材料之行列，成为现代工业四大基础材料之一，应用于人类活动于生产
