毕业论文-相机外壳工艺方案及模具设计

I相机外壳工艺方案及模具设计摘要本文主要是针对相机外壳的注塑模设计，依照设计任务书的要求，对于相机前面板的设计来查阅相关资料确定使用的材料以及材料的主要性能、特征，运用Pro/E画出三维特征和运用AutoCAD画出零件三视图。基于Pro/E的数码相机外壳注塑模设计师对传统设计的创新，利用Pro/E软件完成注塑模的各个环节的设计，先进行塑件的设计，然后运用Pro/E根据塑件的形状可以生成型芯和型腔，最后再标准模架系统下生成型芯、型腔和标准模架的装配图，完成整个模具的设计。Pro/E功能强大、囊括了产品组立、零件设计、NC加工、模具开发、板金件设计、造型设计、铸造件设计、自动测量、机构仿真设计、应力分析、数据库管理等多种功能。它的出现改变了传动的CAD/CAM作业方式，大大缩短了用户开发产品的时间。本课题介绍了模具国内外发展现状，而且从相机外壳模具情况出发，进行塑件成型工艺分析，模具的成型零部件、浇注系统、温度调节系统、合模导向结构、脱模结构等设计，并进行了模架的选择、注塑机的选择、模具开模仿真。使用Pro/E软件进行模具设计可大大缩短设计和制造周期，提高产品设计准确性，降低设计成本。关键词：AutoCAD；Pro/E；注塑模；浇注系统IIAbstractThisarticleismainlyinjectionmolddesignforcameracase,inaccordancewiththerequirementsofthedesigntaskbook,accesstorelevantinformationforthedesignofthefrontpanelofthecameratodeterminetheperformancecharacteristicsofthematerialsusedaswellasthematerials,theuseofPro/E,drawthree-dimensionalcharacteristicsanduseAutoCADdrawpartoftheview.InjectionmolddesignersbasedthePro/Edigitalcameracasethetraditionaldesigninnovation,theuseofPro/Esoftwaretocompletetheinjectionmoldallaspectsofthedesign,thedesignofplasticpartsfirst,andthentheuseofPro/Eaccordingtotheshapeoftheplasticpartsgeneratethecoreandcavity,andfinallystandardmoldsystemswellsmoldingcore,cavityandstandardmoldframeassemblydrawings,completethedesignoftheentiremold.Pro/Epowerful,includetheproductassembly,partdesign,NCmachining,molddevelopment,castingdesign,sheetmetaldesign,design,automaticmeasurement,mechanismsimulationdesign,stressanalysis,databasemanagementandotherfunctions.IthaschangedthetransmissionofCAD/CAMpractices,greatlyreducingtheuserproductdevelopmenttime.Thistopicdescribesthemolddevelopmentintheworld,andthedeparturefromthecamerashellmold,plasticmoldingprocessanalysis,moldmoldingparts,injectionsystem,temperaturecontrolsystem,clamping-orientedstructure,moldreleasestructuredesignandthechoiceoftheselectionofmoldframe,theinjectionmoldingmachine,moldopeningsimulation.UsePro/Esoftwareformolddesigncangreatlyshortenthedesignandmanufacturingcycle,improvetheaccuracyofproductdesign,andreducedesigncosts.Keywords:AutoCAD;Pro/E;injectionmold;gatingsystemIII目录第一章绪论....................................................................................................................................11.1国内外模具发展状况..........................................................................................................11.2研究的内容、目的及研究意义..........................................................................................1第二章相机外壳注塑模具设计......................................................................................................42.1塑件结构特征分析..............................................................................................................42.2塑件注塑成型的工艺分析..................................................................................................42.3模具浇注系统的布置..........................................................................................................62.4流道及浇口设计..................................................................................................................72.4.1主流道的设计...........................................................................................................72.4.2浇口设计...................................................................................................................72.5分型面的设计......................................................................................................................82.5.1分型面的设计原则...................................................................................................82.6凹模和凸模..........................................................................................................................92.6.1凹模和凸模的结构设计...........................................................................................92.7注塑机...............................................................................................................................102.7.1塑件体积计算.........................................................................................................112.8注塑机的选择....................................................................................................................112.9注塑机的参数校核............................................................................................................12第三章排气系统的设计................................................................................................................133.1排气系统的重要性............................................................................................................133.1.1排气对塑件成形质量的影响.................................................................................133.1.2排气方式.................................................................................................................133.2排气槽的作用....................................................................................................................133.3排气槽的设计....................................................................................................................143.3冷却系统....................................
