轴承保持架注塑模具设计
摘要
这次设计的课题对一个塑件制品，名称为轴承保持架，在三维方面是基于UG三维建模软件对轴承保持架塑件塑料件进行三维软件建模，并需要完成对这个该塑料件的原始结构分析，通过分板及了解可以知道的情况这个塑件内部结构及塑件外形相对比较简单，整体形状比较规则，壁厚平均分布相对合理。在通过充分考虑模具尺寸大小与生产效益等多方面因素后，本次设计拟定采用一模一腔的型腔分布，在浇注方面采用了侧浇口进料的大水口模架系统模架。注塑模具是一种以特定的型腔、型芯等结构形式让塑胶原料成型的一种新型生产工业，在模具设计前需要通对塑料件的材料选择以及成型工艺进行分析和注塑成型机的确定，所以本次模具设计选择了比较合适的注塑成型机并对注塑机多个重要参数进行了校核与计算。并对塑料模的塑件分模面进行选择设计。经过多种数据的比较与分析等，从而综合各种因素选择一个最合理的方案。
并将模具所有零件及装配图绘制成CAD电子图档，通过计算机辅助设计软件CAD图的绘画，并对塑件的各机构及模架进行了设计绘画，并绘制转化二维装配图及主要的零件图。然后对模具的各种重要的参数进行了一系统的设计与校核，从而完成整个设计。

Abstract
The topic of this graduation project is a plastic part, named bearing cage. In the three-dimensional aspect, it is based on the UG three-dimensional modeling software to carry on the three-dimensional software modeling for the plastic part of the bearing cage, and needs to complete the original structure analysis of the plastic part. Through the plate division and understanding, we can know the situation. The internal structure and shape of the plastic part are relatively simple, and the whole process is relatively simple The average distribution of wall thickness is relatively reasonable. After fully considering the mold size and production efficiency and other factors, the cavity distribution of 1 is proposed in this design, and the side gate feeding large nozzle mold base system mold base is adopted in the pouring. Injection mold is a new type of production industry that uses specific cavity, core and other structural forms to make plastic materials molding. Before the mold design, it is necessary to analyze the material selection of plastic parts and the molding process, and determine the injection molding machine. Therefore, this mold design selects a more appropriate injection molding machine, and checks and calculates several important parameters of the injection molding machine 。 The parting surface of the plastic part is selected and designed. After a variety of data comparison and analysis, so as to integrate various factors to choose the most reasonable scheme.
All parts and assembly drawings of the mould are made into CAD electronic drawing files. Through the drawing of CAD drawing of CAD software, the mechanism and mold base of the plastic parts are designed and drawn, and the two-dimensional assembly drawing and the main part drawing are drawn. Then the important parameters of the mold are designed and checked systematically, so as to complete the whole design.
Key words: check; injection mold; mold design; plastic molding
