1、 I 摘要摘要 注塑生产因其生产效率高、产品质量好、材料消耗少、生产成本低而获得广 泛应用。我国的注塑模具工业发展迅速,现今,注塑模具的设计生产约占整个塑料 模具设计生产的三分之一。随着塑料工业生产的发展,塑料工业产品的品种和数量 不断增加,产品更新换代加快,对产品质量、样式和外观也不断提出新要求,对注塑 模具质量要求也越来越高。 日用品中的笔记本，有时采用精度和强度不太高的塑料传动，由于塑料具有 可塑性强，密度小、比强度高、结缘性、化学稳定性高、外观多样的特点，因而 受到越来越多的厂家及人民的喜爱。 本次是对笔记本的 RAM DOOR 网孔盖进行注塑模设计，利用 UG 软件对塑件进 行了实体

2、造型，明确了设计思路，确定了注塑成型工艺过程,详细地介绍了注塑模 具的浇注系统、温度调节系统和顶出系统的设计过程，并对各个具体部分进行了 详细的计算和校核。通过本设计，可以对注塑模具的结构和工作原理有一个初步 的认识。 关键词关键词: : 注塑模具;模具设计;笔记本的 RAM DOOR 网孔盖 II ABSTRACT Injection molding because of its high production efficiency, product quality, less material consumption, low production costs and is widely
