毕业设计(论文)ABS塑件的注射成型工艺分析及模具设计学生姓名:学号:专业:指导教师:学院:摘要I摘要本文主要是关于ABS塑料槽的注射成形工艺分析及模具设计。首先阐述了对塑件在模具中的位置布局和分型面的选择；选择浇注系统与排溢系统；对于成型零件的结构、合模导向机构、推出机构、温度调节系统的设计方案做了充分的论证，并且优化选择最合理的成型方案。通过对型芯支撑板和型腔板的设计计算，充分保障了模具的优良使用性能，简化了模具的结构，从而让模具结构更加紧凑。在本次设计中型芯型腔的计算是重点，不能有疏忽，一定要计算精准，因为型芯型腔是保证模具使用性能好坏的关键。模具设计时结构要简便，模具结构要紧凑。为此，各种制图软件的应用必不可少，主要有UG/CAD/PRO-E等。总之本文的最重要的任务是塑料槽注射模的设计，换句话说就是设计一副注射模具来大批量生产塑料槽塑件产品，从而来实现机械自动化，提高产品的产量。关键词：塑料槽；注射模；模具结构；注射工艺ABSTRACTIABSTRACTThisarticleisabouttheABSplasticinjectionmoldinggroovesTechnologyAnalysisandDieDesign.Firstexpoundedbyplasticinthemoldpartinglinepositionandlocation,selectthegatingsystemandoverflowdischargesystem.Formoldingpartsofthestructure,moldguidemechanism,pushingmechanism,temperaturecontrolsystemdesigntodoafulldemonstration,choosethemostreasonableandoptimizedesign.Bythecalculationofthecoresupportplateandcavityplate,adequateprotectionoftheexcellentperformanceofthemold,simplifyingthedesignofthemold,sothatmoldmorecompact.Inthisdesign,thecorecavitycomputingisthekeypoint,thecalculationmustbeaccurate,becausethecorecavitymolddesignisanimportantfactortoensuretheperformanceisgoodorbad.Inaddition,takingintoaccountarticleinjectionmoldingprocessrequirements,avarietyofgraphicssoftwareapplicationsisessential,mainlyinUG/CAD/Pro-Eandsoon.Keywords:plastictank;injectionmolding;moldstructure;injectionprocess目录I目录1绪论........................................................................................................................11.1塑料简介..............................................................................................................11.2注塑成型及注塑模..............................................................................................21.3毕业设计的意义与目的......................................................................................22塑料材料分析........................................................................................................52.1塑料材料的基本特性..........................................................................................52.2塑件材料成型性能..............................................................................................52.3塑件材料主要用途..............................................................................................53塑件的工艺分析....................................................................................................73.1塑件的结构设计..................................................................................................73.2塑件尺寸及精度..................................................................................................83.3塑件表面粗糙度..................................................................................................83.4塑件的体积和质量............................................................................................104塑件的成形工艺设计与模具结构设计.................................错误!未定义书签。4.1注射成型工艺过程分析....................................................................................114.2浇口种类的确定................................................................................................114.3型腔数目的确定................................................................................................134.4注射机的选择和校核........................................................................................134.4.1注射量的校核.............................................................................................134.4.2分型面和零件检验.....................................................................................144.4.3注射机的尺寸检验.....................................................................................155注射模具结构设计..............................................................................................175.1分型面的设计....................................................................................................175.2型腔的布局........................................................................................................175.3浇注系统的设计................................................................................................185.3.1浇注系统组成.............................................................................................185.3.2确定浇注系统的原则.................................................................................185.3.3主流道设计.................................................................................................185.3.4分流道设计.................................................................................................195.3.5浇口设计.....................................................................................................205.3.6冷料穴的设计.............................................................................................205.4注射模成型零部件的设计................................................................................215.4.1成型零部件结构设计.................................................................................22目录II5.4.2成型零部件工作尺寸的计算......................................................................225.4.3成型零件尺寸计算......................................................................................225.5脱
