塑料盒注塑模设计

洛阳理工学院毕业设计（论文）I塑料盒注塑模设计摘要本课题主要是设计给定的塑料盒子的注塑模,通过对塑件进行工艺的分析和比较,最终设计出一副能生产出符合要求的制件的注塑模。结合塑件的结构特点，纵观整个模具结构，对模具的浇注系统、排气系统、推出及复位机构等进行了详细的设计和说明，对注塑机进行了慎重选择和认真校核，并对侧型芯的推出及复位机构进行了重点设计说明。盒子结构简单，精度一般，但是盒子有内缘使模具的结构变得复杂，零件相应增多。为缩短模具制造周期，在设计过程中选用了大量标准件，个别标准件需经再加工，这在装配要求中有详细说明。关键词：塑料盒子，模具，侧型芯，注射机洛阳理工学院毕业设计（论文）IIDesignplasticinjectionmoldingofgivenplasticboxABSTRACTThissubjectmainlydesigngivenplasticboxofplasticsinjectionmolding,throughtechnicalanalysisandcomparison,thefinaldesignapaircanproducetomeettherequirementsoftheproduct'sinjectionmold.Combinedwiththestructurecharacteristicsofplasticparts,throughoutthewholemoldstructure,mouldpouringsystem,exhaustsystems,launchandresetinstitutesdetaileddesignandinstructionsforinjection,thecarefulchoiceandserious,andcheckedthelaunchoflateralcoresandresetinstitutionhascarriedonthekeydesigndescriptions.Boxstructureissimple,precisioninnerboxhaveso-so,buttodiestructurecomplicated,partsincreasedaccordingly.Forshorteningthemouldmanufacturingcycle,inthedesignprocessofchosetoindividualstandardfastener,shallbeapprovedbyreprocessing,thisinassemblyrequirementsaredetailedinstructions.Inthedesignprocess,refertoalotofmaterial,manuals,standards,etc,combiningtheteachingmaterialofinjectionmoldonstructureshavefurthermasterunderstanding,broadenedourhorizons,richknowledge,moulddesignforfutureindependentlyaccumulatedexperience.KEYWORDS:Plasticbox，Mould,Lateralcores,Injectionmachine洛阳理工学院毕业设计（论文）III目录前言................................................................................................1第1章塑料注射模具的设计步骤和结构组成................................41.1塑料注射模具的设计步骤及内容........................................41.1.1任务书.........................................................................41.1.2资料收集分析.............................................................41.1.3选择成型设备.............................................................51.1.4确定模具类型的主要结构方案..................................51.1.5绘制模具图.................................................................51.2塑料注射模具的结构组成和作用........................................6第2章盒子塑料件...........................................................................82.1塑料件的结构和特点...........................................................82.2塑料件的材料.......................................................................82.2.1塑料简介.....................................................................82.2.2塑料的成型工艺特点.................................................92.2.3工程塑料（ABS）的特性及注射工艺性....................92.2.4材料ABS的注射成型过程及工艺参数....................112.3盒子塑料件的参数.............................................................12第3章注射机的选用.....................................................................133.1选用注射机的方法和原则.................................................133.2注射机的种类和应用范围.................................................133.3注射机的选用.....................................................................143.3.1注射机的初步选定：...............................................143.3.2注射机的参数校核...................................................15第4章塑料注射模具设计.............................................................174.1型腔数目和分型面的选择.................................................174.2型芯和型腔.........................................................................174.2.1型芯和型腔的结构...................................................174.2.2型芯和型腔的成型部分尺寸....................................18洛阳理工学院毕业设计（论文）IV4.2.3侧抽芯的设计...........................................................194.3浇注系统.............................................................................204.3.1浇注系统的作用与组成............................................204.3.2浇注系统的设计.......................................................204.4推出机构.............................................................................214.4.1推出机构的作用和种类............................................214.4.2制件推出机构的设计...............................................224.4.3侧型芯推出机构的设计............................................234.5导向机构.............................................................................244.5.1导向机构的作用和组成............................................244.5.2导柱、导套的选用...................................................244.6冷却和排气系统.................................................................254.6.1冷却系统...................................................................254.6.2排气系统..................................................................254.7模架的设计.........................................................................264.8注射模的设计结果参数.....................................................284.9模具的装配过程与工作过程..............................................284.9.1模具的装配...............................................................284.9.2模具工作过程...........................................................29结论..............................................................................................30谢辞................................................................................................31参考文献................................................................
