油缸油窗端盖注塑模具设计 摘 要 塑料注塑模是一种用来生产塑料零件的模具。它被安装在塑料注塑机上，由塑料注塑机将塑料颗粒融化成热熔体，经过合模、高压注塑、高压冷却定型、开模、推出制件等工序，获得所需的塑料制品。近10年来，由于塑料具有的良好特性，使得塑料制品获得愈来愈广泛的应用，塑料模已成为广泛使用的一类模具。据统计，塑料制品总重量大约35％是用于注射成型，80％以上的工程塑料制品都要采用注射成型方式生产。模具设The fuel tank of the oil window end cap injection mold design ABSTRACT Plastic injection mold is used to produce plastic parts of a mold. It was installed in the plastic injection molding machine, plastic injection molding machine by the plastic particles melt into a hot body, after mold, high pressure injection molding, high-pressure cooling shape, the mold, parts such as the introduction of processes to obtain the necessary plastics.  The past 10 years, as a result of the good characteristics of plastic with which to obtain more and more plastic products widely used, plastic has become a widely used tool for a class. According to statistics, the total weight of plastic about 35% for the injection molding, engineering plastics more than 80% of all products produced using injection molding. The design of the fuel tank of the oil window end cap for the injection mold base design, the use of Pro / E software for the plastic parts for the solid modeling, the structure of the plastic parts of the process analysis. A clear idea of the design to determine the injection molding process and the specific part of a detailed calculation and checking. The structure of such a design work to ensure that the use of a reliable tool to ensure the co-ordination with other parts. Finally, a set of autoCAD drawing die assembly drawing and parts drawing. The fuel tank of the oil window end cap through the issue of the injection mold base design, consolidate and deepen the knowledge, and achieved satisfactory results, to achieve the desired design intent.
