摘 要

注射成型加工質(zhì)量的優(yōu)劣是塑料加工業(yè)技術(shù)發(fā)展水平的標(biāo)志之一，同時(shí)反映了模具設(shè)計(jì)和制造的水平。詳細(xì)介紹了刷座注塑模具設(shè)計(jì)的整個(gè)過程。首先通過對(duì)塑件的結(jié)構(gòu)和成型工藝分析，確定塑件的分型面與澆口結(jié)構(gòu)；然后再進(jìn)行模具零件設(shè)計(jì)，如成型零件、脫模機(jī)構(gòu)等等。同時(shí)在整個(gè)設(shè)計(jì)過程中，還要通過計(jì)算機(jī)輔助工具CAD/CAE進(jìn)行設(shè)計(jì)。重點(diǎn)闡述如何利用CAE軟件，將注射成型中塑料熔體在型腔內(nèi)充填模擬，通過對(duì)模擬結(jié)果的分析與評(píng)判，有效預(yù)防了原模具設(shè)計(jì)方案用于實(shí)際生產(chǎn)時(shí)可腀@魷值奈侍?，译E齪細(xì)竦牟貳６誚峁股杓品矯媯氐悴雋順萋殖萏醭樾凈股杓埔?，模緡裔构紧村帰簜b懟�

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.
