TBQ-51滚轮注塑模具设计 摘要 模具是一种新型的技术产业，对于工业的进步以及经济发展都起到非常关键的作用，如今在全球工业发展当中，特别是发达国家对于模具的重视度都比较高，也被称作为工业之母，根据数据显示，如今在全球的工业产品当中，超过一半以上为模具产品，尤其是汽车制造当中，对于模具的依赖程度更高。我国模具发展速度比较快，经历从零到有的过程，并且已经迈入全球模具制造业大国的行列，能够实现中高端模具的出口生产，随着经济发展以及市场开放，模具市场的竞争也越加激烈，未来关于高端高精度模具的生产和制造是一个主要趋势，市场需求也会更大。 本次设计的是关于滚轮注塑模具，滚轮是比较普遍的一种产品，需要分析这种产品的使用和工艺要求，选取POM+30%GF材料，通过对产品尺寸分析，确定分型面和型腔布置，并且计算产品的注射体积，依次选取满足生产要求的注射机型号，并且设计浇注系统以及推出机构，计算成型零件的工作尺寸等，最终完成模具装配图零件图图纸要求，以及说明书的写作要求。 关键词：注塑模；滚轮；浇注系统；POM+30%GF ABSTRACT Mold is a
