电视遥控器注射模具设计

齐齐哈尔大学毕业设计（论文）用纸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。本文中针对电视遥控器注射模具制定出合理的设计结构，其中包括成型部分及其零部件设计，浇注系统设计，脱模机构设计，冷却系统设计等。根据分析，设计了一套塑料注射模具，并对模具以及主要零件进行了CAD绘图。关键字：注射模具浇注系统脱模机构冷却系统齐齐哈尔大学毕业设计（论文）用纸IIAbstractThetechniquelevelofmoldingtoolwhichhasbecameanimportantmarkingtomeasurethelevelofanationalproduct.Somehigherdemandssuchashighquality,highprecision,shorttimeofR&Dandsoonwereputforwardsincetherapiddevelopmentofplasticindustry,whethertheycanadapttotheserequirementshasbecominganimportantfactorforthedevelopmentofmoldingproducer.Themoldtechnologyisacomprehensivedisciplinethatcombinesmechanicalengineering,computerapplication,automaticcontrol,numericalcontroltechnologyandsoon.Inthispaper,itintroducedthedesignprocessoftheinjectionmoldofTelevisionremotecontrolkneadingboard,includingtheshapeofpartdesign,thedesignoffeedsystempushsystemandcoolingsystem,moldingpartandfinalassemblystructure.Dependingontheanalysis,aplasticinjectionmouldhasdesigned,andtheinjectionplasticmouldandtheimportantpartsaredrawnoncomputerbyAutoCAD.Keywords:InjectionmoldDrawingofpatternsorganizationFeedsystemCoolingsystem齐齐哈尔大学毕业设计（论文）用纸I目录摘要............................................................................................................ⅠAbstract...........................................................................................................Ⅱ第1章绪论....................................................................................................11.1选题的依据和意义.........................................................................11.2塑料行业在我国国内的发展状况.....................................................11.3.1产需矛盾..................................................................................21.3.2产品结构、企业结构等方面......................................................21.3.3产品水平..................................................................................21.3.4工艺装备水平...........................................................................31.3.5模具行业的发展趋势................................................................3第2章方案分析...........................................................................................42.1设计任务........................................................................................42.2产品分析........................................................................................42.3塑件所用塑料名称、性能及工艺参数..............................................52.4塑件结构要素.................................................................................52.4.1塑件脱模斜度：........................................................................52.4.2塑件精度等级的选用................................................................62.4.3圆角设计..................................................................................62.5注射机的选择.................................................................................62.5.1最大注塑量：...........................................................................62.5.2注射压力：...............................................................................62.5.3锁模力的校核：........................................................................62.5.4开模行程校核：........................................................................72.5.5螺杆转速：...............................................................................7第3章成型部分及其零部件设计....................................................................83.1分型面的设计.................................................................................8齐齐哈尔大学毕业设计（论文）用纸II3.1.1考虑塑件质量...........................................................................83.1.2确保塑件表面质量....................................................................83.1.3考虑模具结构...........................................................................83.2型腔数的确定.................................................................................93.2.1根据所用注射机的最大注塑量确定型腔数目.............................93.2.2根据注射机最大锁模力确定型腔数.........................................103.2.3根据塑件的精度确定型腔数目................................................103.2.4根据经济性确定型腔数目.......................................................103.3凹模结构设计...............................................................................113.3.1凹模型腔的大小尺寸为：.......................................................123.3.2型腔的深度尺寸......................................................................123.4凸模结构尺寸...............................................................................133.4.1凸模/型芯的外形尺寸..............................................................143.4.2凸模/型芯的高度尺寸..............................................................153.5型腔壁厚的计算............................................................................153.5.1型腔的强度及刚度要求..............................................................153.5.2型腔壁厚计算.........................................................................16第4章浇注系统的设计................................................................................
