USB接口插件弯曲模具设计.rar

摘要
模具是一种技术密集、资金密集型产品,在我国国民经济巾的地位也非常重要。模具工业已被我国正式确定为基础产业,并在“十五”中列为重点扶持产业。由于新技术、新材料、新工艺的不断发展,促使模具技术不断进步,对人才的知识、能力、素质的要求也在不断提高。
课题主要完成USB接口插件弯曲模具设计。USB接口插件弯曲模具的开形状为四直角成“口”字形,首先对USB接口插件的材料要求和性能进行了工艺分析,作为USB接口插件,对此形状要求严格,所以不能一次成型,需要二次成型,由此,设计了成形结构方案,采用二次成型的方案,并对模具设计的总体方案进行了确定;然后对模具的具体结构进行了设计计算,选择相应零件的材料和结构;最后设计了模具的总装图和部分零件图。

Abstract
The mold is a technology intensive, capital intensive products, in China's national economy status is very important. Mould industry in China has been formally identified as a basic industry, and in the " fifteen" as a key support industries. As a result of new technology, new material, new technology continues to develop, make mould technology continues to progress, for people's knowledge, ability, quality requirements are also rising.
Main task plete the USB plug-in interface design of the bending die. USB plug-in interface of bending mould opening shape for four right angle into the " mouth" font, first to the USB interface plug material requirements and performance analysis for the process, as the USB plug-in interface, this shape is strict, so can not be shaped at one time, requiring a two molding, thereby, forming structure scheme design, using two once forming scheme, and the mold design of the overall plan are determined; then the specific die structure design calculation, choose the corresponding parts of the material and structure; finally the design of mold parts assembly diagram and diagram.
