1、病床背板丝杆的模具设计 摘 要 随着时代的发展，模具设计及制造的发展也越来越“现代化”，越来越“高效益。当今，模具已经成为塑料制品生产与更新不可或缺的基础和前提，往往在注射模具的设计技术与制造水平上，常可标志一个国家工业化的发展程度。 本次设计对病床背板丝杆进行注塑模具设计。对该塑件进行工艺性分析与工艺计算并确定注射机型号，确定合理的注塑工艺方案。通过大量的查阅文献资料和实验研究，理论和实践结合，进行比较分析，通过查阅图书馆和网上的资料，确定塑料模具的大体结构，进行模具各数据的设计计算。运用 solidworks软件进行三维建模、选择并确定分型面、型腔的分布及确定、设计浇注系统、成型零部件的计

2、算、选择及确定脱模机构和导向机构，最后进行注射机的校核。使用 solidworks 软件在电脑上进行三维建模，再对各个数据进行修正、改进，之后画出模具的总 装配图，各个非标准零部件的零件图。 关键词 ： 病床背板丝杆 注塑模具 三维建模 Hospital Bed Backplane Lead Screw Mold Design ABSTRACT With the development, mold design and manufacturing development of more and more modern, more and more cost-effective.
