文档介绍：摘要
模具工业是国民经济的基础的工业,21世纪以来模具制造行业基本走向是高度集成化、智能化、柔性化和网络化,其最终的目的都是提高产品质量及生产效率,缩短设计及制造周期,降低生产成本,最大程度的提高模具制造的应变能力,满足客户的需求。从目前市场情况来看,塑料模具占主导地位,其发展速度稳定高于模具工业的整体的高速发展。
如今,CAD/CAM/CAE技术在塑料模的设计制造上应用已经越来越普遍,很多模具企业都是使用三维软件对产品零件造型进行分析,及模具主要结构的设计。应用电子信息技术进一步提高了塑料模的设计制造水平,这些不仅缩短了生产前的准备时间,同时也相应缩短了模具的设计和制造周期。
本设计是研究一副液压缸齿条脱螺纹模具,如今模内旋转方式脱螺纹机构主要有手动脱螺纹和机动脱螺纹两种方式。考虑到本设计产品的用途和质量要求,我采用了机动脱螺纹设计。通过本设计来体现以下几个重要环节:①如何平稳脱模,不至于拉伤模具及影响产品的精度;②考虑模具运动安全可靠及开合模周期长短问题;③减少安装工作量,缩短生产准备时间。

Abstract
Modle industry is based of national economy. Since 21 centrury, the basic d of mold manufacturing industry is a highly integrated intelligent,flexible work. The ultimate goal is to improve product quality and production efficiency. Shorten design and manufacturing cycle,reduce production costs,increase the maximum strain,mold,manufacturing capacity to meet customer demand.
Today, CAD/CAM/CAE technology in the application of plastic mold design and manufacturing has e,mon. panies are using three-dimensional of the product parts moldeling software to analyze and design the structure of the mold. Application of electronic information technology to further improve the leve of design and manufacture plastic molds, these not noly shortened the lead time before production, but also the corresponding mold design and shorten the manufacturing cycle.
The design is of a hydraulic cylinder rack off thread die now die of within a spin off thread ,institutions are mainly thread screwamd motor off in two ways. Taking into account the use of the product design and quality requirements. I am off thread used motor design. Installating of the workload,shorten , production lead time . Designed to reflect the passage of this important part of the following;① How smooth mold relesase, and will not strain the precision mold and affect the product. ② Considered safe and reliable movement and mold damping cycle length. ③ Reduce the installation effort , shorten the production lead time.
