变频器壳体注射模设计论文[带图纸].docx

哈尔滨工业大学华德应用技术学院毕业设计(论文)I摘要本论文基于变频器壳体设计,在完成模具参数计算和结构设计的基础上,利用三维设计软件完成模具的实体设计,综合了成型工艺分析,模具结构设计,最后到模具零件的加工方法,模具总的装配等一系列模具生产的所有过程。能达到很好的学以致用的效果。在设计该模具的同时总结了以往模具设计的一般方法、步骤,模具设计中常用的公式、数据、模具结构及零部件的选择等。把以前学过的基础课程融合、综合应用到本次设计当中来。该注射模最显著的特征是利用斜导柱和侧滑块配合进行侧抽芯。首先,简要介绍了模具行业现在的情况和未来的发展趋势。提到了限制模具发展的因素。其次,对制品进行了工艺性分析及材料的性能分析,确定了模具设计的整体方案。根据塑料模具设计手册和相关经验公式进行了必要的计算及校核,根据计算结果选用了注射机又进一步完成了标准件的选择和对非标准件的设计。关键词注塑模变频器壳体斜导柱侧抽芯Pro/E哈尔滨工业大学华德应用技术学院毕业设计(论文)IIAbstractThispaperisbasedconvertershelldesign,completemolddesignparametersandstructurecalculationsbasedontheuseofthreedimensionaldesignsoftwaretocompletethephysicaldesignofthemold,moldingprocesscombinesanalysis,molddesign,moldpartsandfinallytoprocessingmethods,moldassemblyandaseriesoftotalproductionofallprocesses.Canapplytheirknowledgetogoodeffect.Insummary,whilethedesignofthemolddiedesignpastthegeneralmethods,procedures,formulascommonlyusedinmolddesign,data,andpartsofthemoldstructurechoice.Thepreviouslylearnedbasiccoursesintegration,integratedapplicationtothisdesignistoimprove.Theinjectionmoldthemoststrikingfeatureistheuseofbevelpillarandsidesliderwiththesidecorepulling.First,abriefdescriptionofthemoldindustry,thecurrentsituationandfuturetrends.Mentionedfactorsthatlimitthedevelopmentofmold.Secondly,theproductsforaprocessofanalysisandmaterialpropertiesanalysistodeterminethemolddesignoftheoverallprogram.Accordingtoplasticmolddesignmanualandthenecessaryrelevantexperienceformulacalculationandverification,selectedaccordingtoresultsoftheinjectionmachinecompletedafurtherselectionofstandardpartsandpiecesofnonstandarddesign.KeywordsInjectionmoldconverterhousingBevelcolumnsidecorepullingmechanismPro/E哈尔滨工业大学华德应用技术学院毕业设计(论文)III目录摘要........................................................................................................................IAbstract.................................................................................................................II第1章绪论.........................................................................................................11.1模具工业在国民经济中的地位...............................................................11.2各种模具的分类和占有量.......................................................................21.3我国模具工业的现状...............................................................................31.4世界五大塑料生产国的产能状况...........................................................51.5我国模具技术的现状及发展趋势...........................................................71.5.1我国模具技术的现状.........................................................................71.5.2我国模具技术的发展趋势.................................................................8第2章注塑件的工艺性.....................................................................................92.1塑料制品的设计分析...............................................................................92.2塑件的体积和质量.................................................................................102.3ABS材料工艺性分析.............................................................................102.3.1材料基本特征...................................................................................102.3.2材料主要用途...................................................................................112.3.3材料成型特点...................................................................................122.4塑料制品的工艺性分析.........................................................................132.4.1收缩性...............................................................................................132.4.1.1塑件结构设计对塑件收缩的影响...........................................132.4.1.2模具结构设计对塑件收缩的影响...........................................142.4.2脱模斜度...........................................................................................142.4.3壁厚...................................................................................................152.4.4侧孔...................................................................................................152.4.5圆角...................................................................................................162.4.6塑件的尺寸精度及表面质量...........................................................162.4.6.1尺寸精度...................................................................................162.4.6.2塑件的表面质量.......................................................................17哈尔滨工业大学华德应用技术学院毕业设计(论文)IV2.5本章小结.................................................................................................17第3章注塑成型的准备...................................................................................183.1注塑成型工艺简介.................................................................................183.2注塑成型工艺条件.................................................................................193.3注塑机的选择.........................................................................................213.3.1注塑机简介.......................................................................................213.3.2注塑机基本参数...............................................................................213.3.3选择注塑
