设计简介
摘 要
注射成型加工质量的优劣是塑料加工业技术发展水平的标志之一，同时反映了模具设计和制造的水平。详细介绍了刷座注塑模具设计的整个过程。首先通过对塑件的结构和成型工艺分析，确定塑件的分型面与浇口结构；然后再进行模具零件设计，如成型零件、脱模机构等等。同时在整个设计过程中，还要通过计算机辅助工具CAD/CAE进行设计。重点阐述如何利用CAE软件，将注射成型中塑料熔体在型腔内充填模拟，通过对模拟结果的分析与评判，有效预防了原模具设计方案用于实际生产时可能出现的问题，以生产出合格的产品。而在结构设计方面，重点阐述了齿轮齿条抽芯机构设计要点，模具结构紧凑、合理。

Injection molding procesing quality is the one of symbols of the quality that plastic procesing industry and technogical devlepment.also deflected the mold design and manufacturing level.Details on the entire procesing of the Brush Block Injection Mold Design.At the first,the structure of the parting line and sprue was determined based on the analysis of the structure and forming technology of the plastic.Then design for the mold parts,such as molding parts,demoulding mechanism,and so on.At the same time throughout the design process, through the computer aided design CAD and CAE tools.Details on how to use CAE tool.For simulating the filling process of plastic melts in the cavity of injection moulds. The analysis on the analog result can help effectively modify the design scheme and prevent the problems that may occur in the production And in the design of structure,The key points in designing the side core-pulling mechanism with gears and rack were stated in detail. The mould is compact in structure and effective in operation.
Keywords: Injection Molding,Design of injection mould,Technique analysis.
