快速插头塑料磨具设计
摘要
随着社会的发展,不同品种和功能的塑料的出现,塑料产品与我们的日常生活越来越密切。
RJ45水晶头接线座是我们日常生活中经常接触到的接口设备之一,其主要用于连接网卡端口、交换机、电话等;计算机网络用的RJ45接线座是标准的8位模块化接口。本次毕业设计的题目是“RJ-45水晶头接线座注塑模设计”。该设计主要是通过对塑件的结构形状、尺寸精度和成型要求来进行注射成型工艺的可行性分析,并完成注射模具的设计。其中,塑件的成型工艺分析主要包括:塑料的成型特性、塑件结构特点、表面粗糙度、达到的使用要求和脱模分析。以此来确定型腔数目、分型面位置、浇注方式、脱模方式等。最后完成一幅完整的模具设计总图,包含成型部分、合模导向机构、推出机构、侧向分型抽芯机构、冷却系统等的设计,设计的过程包括了对成型零件的计算、抽芯机构的校核计算等。在设计的过程主要应用了PRO/E软件完成对塑件的实体造型,并对塑件的体积、质量等进行分析,最后通过Auto CAD完成零件图和装配图,并最终完成塑料模具的设计过程。

Abstract
With the development of society, different varieties and function plastic appearance in our lives, plastic productions have closer to our daily lives.
RJ-45 terminal block is one of the interface device in our daily life that we e into contact with. It often used work cards, switches, telephones, etc; work wiring blocks using a standard 8-bit modular interface. The subject of the graduation project is “injection mould design for RJ-45 terminal block ” Through the feasibility analysis the plastic part structure and shape, the size and shape require for injection molding process, plete the injection mold design. Analyze and determine the die's parting plane, the number of die cavity, gate’s forming, gate’s position and its size. Besides, we need to analysis the stress, the registration and the guide mechanism's design of the dies, the mould emptier design, the cooling system's design, etc. At last, we should finish the die's general assembly drawing. The design have mostly used the Pro/E soft to progress the solid modeling, then analysis the volume and quality of the plastic part. And it has been through the Auto CAD to finish de detail drawing and the assembly drawing, then finish the design processes of injection mold.
