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DesignplasticinjectionmoldingofgivenplasticboxABSTRACTThissubjectmainlydesigngivenplasticboxofplasticsinjectionmolding,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...........
