本科毕业设计（论文）题目遥控器面板注塑模具设计院（系部）机械与动力工程系专业名称机械设计制造及其自动化年级班级07机制2班学生姓名丁东东指导教师李章东年月日河南理工大学万方科技学院本科毕业论文I摘要模具生产技术水平的高低，已成为衡量一个国家产品制造水平高低的重要标志。塑料工业的飞速发展，对注塑模具的设计与生产提出了质量好、制造精度高、研发周期短等越来越高的要求，能否适应这种需求已成为模具生产企业发展的关键因素。模具技术是融合机械工程、计算机应用、自动控制、数控技术等学科为一体的综合性学科。随着家电市场竞争的白热化，家电外壳设计成为了衡量家电外壳色彩、手感、精度的重要一环，进而对设计提出了新的需求。本毕业设计正是从实际使用出发，进行遥控器面盖注塑成型模具的设计。本设计是对遥控器面盖进行的注塑模型设计，利用Pro/E软件对塑件进行了实体造型，并对塑件结构进行了工艺剖析。首先对遥控器的结构工艺性进行分析，清楚了解塑件；由生产批量初步选定注射机型号；然后对本次模具设计的各个方案进行论证分析，从选定方案中对浇注系统、成型工作零件的计算及校核，从中确定模架，推出与抽芯机构的计算及校核，冷却系统的计算及其水道布置设计，在最后对排气和导向与定位结构的设计。其次利用注塑模具设计原理对各个具体系统零件进行详细的计算和校核，使设计出的结构可确保模具可靠运行，在此基础上完成了本毕业论文的写作。最后绘制整套模具的装配图和零件图。通过对本课题遥控器模型设计，我重温了注塑成型与模具设计知识，使书本知识和理论与实际生产相结合，加强了对注塑模具设计知识的理解，使自己能运用书本知识设计出基本符合生产要求的模具。在论文中我充分地运用了大学期间所学到的知识。进行了研究，巩固和深化，达到了预期的设计意图。关键字：注射模具浇注系统脱模机构冷却系统河南理工大学万方科技学院本科毕业论文IIAbstractThetechniquelevelofmoldingtoolwhichhasbecameanimportantmarkingtomeasurethelevelofanationalproduct.Somehigherdemandssuchashighquality,highprecision,shorttimeofR&Dandsoonwereputforwardsincetherapiddevelopmentofplasticindustry,whethertheycanadapttotheserequirementshasbecominganimportantfactorforthedevelopmentofmoldingproducer.Themoldtechnologyisacomprehensivedisciplinethatcombinesmechanicalengineering,computerapplication,automaticcontrol,numericalcontroltechnologyandsoon.Asthecompetitionintheappliancemarketgrowing,theapplianceshellcolor,feelingandaccuracybecameanimportantpartofthedesignandmadenewdemands.Thispaperfocusontheactualconductandtrytodesignremotecontrolcoverinjectionmold.Thisdesignistheinjectionmodeloftheremotecontrolcover,usePro/Esoftwareforthesolidmodelingplasticpartsandanalysisthestructureoftheprocess.Firstly,thestructureoftheremotecontrolwasanalyzedtogetaclearunderstandingofplasticparts.Thenselecttheinjectionmachinemodelbytheinitialproductionbatch.Thirdly,analyzethevariousoptions,selecttheprogram.Thecalculationandcheckingofthegatingsystemandformingworkingpartsdeterminethemold,putforwardthecoremechanismcalculationandcheckingandconfirmthecalculationandchannellayoutofthecoolingsystem.Finally,designtheorientationandstructureoftheexhaustsystem.河南理工大学万方科技学院本科毕业论文IIIFurthermore,weusetheprincipleoftheinjectionmolddesigntocalculateandverifythevariouspartsindetails,sothatthedesignedstructurecanoperatereliablly.Atlast,drawtheassemblyandpartpictureforthewholesetofthemold.Baseonit,Iwritethispaper.Thankstothedesigningofthisremotecontrolmold,Ireviewtheknowledgeoftheinjectionmoldingandmolddesignandputthetheoryintopractice.Italsomakemeunderstandtheknowledgeoftheinjectionmolddesignmore,whichcanhelpmetousethebookknowledgetodesignamoldmatchedthebasicproductionrequirement.Inthepaper,Imakefulluseoftheknowledgeacquiredduringuniversitytoresearching,andachievethedesiredintent.Keywords:InjectionmoldDrawingofpatternsorganizationFeedsystemCoolingsystem河南理工大学万方科技学院本科毕业论文I目录前言.....................................................11绪论...................................................21.1课题研究的目的及意义................................21.2国内外研究状况......................................31.3课题研究基本设计思路和研究手段......................51.4论文结论和成果形式..................................62方案分析................................................72.1设计任务.........................................72.2产品分析.........................................72.3塑件所用塑料名称、性能及工艺参数.................82.4塑件结构要素....................................112.4.1塑件脱模斜度：..............................112.4.2塑件精度等级的选用..........................112.4.3圆角设计....................................112.5注射机的选择....................................112.5.1注射机相关参数计算与校核....................112.5.2注射压力：..................................132.5.3锁模力的校核：..............................132.5.4开模行程校核：..............................142.5.5螺杆转速：..................................143成型部分及其零部件设计.................................163.1分型面的设计....................................163.1.1考虑塑件质量................................163.1.2确保塑件表面质量............................163.1.3考虑模具结构................................163.2型腔数的确定....................................173.2.1根据所用注射机的最大注塑量确定型腔数目.......173.2.2根据注射机最大锁模力确定型腔数..............183.2.3根据塑件的精度确定型腔数目..................183.2.4根据经济性确定型腔数目......................183.3凹模结构设计....................................193.3.1凹模型腔的大小尺寸计算......................203.3.2型腔的深度尺寸计算..........................213.4凸模结构尺寸....................................213.4.1凸模/型芯的外形尺寸计算.....................233.4.2凸模/型芯的高度尺寸计算.....................23河南理工大学万方科技学院本科毕业论文II3.5型腔壁厚的计算..................................243.5.1型腔的强度及刚度要求........................243.5.2型腔壁厚计算................................254浇注系统的设计.........................................264.1浇注系统的组成及设计原则........................264.1.1浇注系统的组成..............................264.1.2浇注系统的设计原则：........................264.2主流道的设计....................................274.2.1主流道分析..................................274.2.2主流道的结构设计............................274.2.3主流道浇口套设计............................294.3分流道的设计.......................................304.3.1分流道的形状和尺寸..........................304.3.2分流道的分布设计
