圆珠笔笔盖注射模设计摘要：《塑料成型工艺与模具设计》课程设计是我们在学完了大学的全部基础课、专业基础课以及专业课后进行的。这是我们在进行毕业设计之前对所学的各科课程一次深入的综合性总复习，也是一次理论联系实际的训练。因此，他在我们的大学四年生活中占有重要的地位。我这次设计的是圆珠笔笔管的模具，有零件图、成型零部件，模具装配图各一张。首先我们要熟悉零件及其零件的材料，题目所给的零件是圆珠笔笔管。了解了圆珠笔笔管作用，接下来根据零件的性质初定一种注射机，之后进行模具的设计与计算（包括型腔的数目与配置、分型面的位置、浇注系统的设计、排气系统、冷料穴的设计、成型零部件的设计、侧向分型与抽芯机构设计、脱模机构的设置、冷却系统的设计、压力机的校核），最后根据计算的结果画出装配图及其成型零部件。对于一个模具专业的即将毕业的学生来说，对塑料模的设计已经有了一个大概的了解。此次课程业设计，培养了我综合运用多学科理论、知识和技能，以解决较复杂的工程实际问题的能力，主要包括设计、实验研究方案的分析论证，原理综述，方案方法的拟定及依据材料的确定等。它培养了我树立正确的设计思想，勇于实践、勇于探索和开拓创新的精神，掌握现代设计方法，适应社会对人才培养的需要。关键字：模具圆珠笔设计Abstract:《PlasticFormingTechnologyandDieDesign》CourseDesignisconductedafterthecompletionofallbasiccourses,professionalbasiccoursesandprofessionalcoursesoftheUniversity.Thisisacomprehensiveandcomprehensivereviewofallthecourseswehavelearnedbeforethegraduationproject,anditisalsoatheoreticalandpracticaltraining.Therefore,hehasanimportantpositioninourfour-yearlife.Idesignedthistimewiththepentubeoftheball-pointpen,havethepartdrawing,theformingcomponent,themoldassemblydrawingeach.Firstofall,weshouldbefamiliarwiththematerialsofthepartsandtheirparts,andthepartsgivenbythetitleareball-pointpenpipes.theeffectofthepentubeoftheball-pointpenisrealized,andtheinjectionmachineisinitiallysetaccordingtothepropertyofthepart,andthenthedesignandcalculationofthemould(includingthenumberandtheconfigurationofthecavity,thepositionofthepartingsurface,thedesignofthepouringsystem,thedesignoftheexhaustsystem,thecold-materialcavity,thedesignoftheformingpart,Thedesignofthelateralpartingandthecorepullingmechanism,thesettingofthedemouldingmechanism,thedesignofthecoolingsystemandthecheckofthepress,andfinallydrawingtheassemblydrawingandtheformingpartsaccordingtothecalculatedresults.Forstudentswhoareabouttograduateinamold,thereisageneralunderstandingofthedesignofplastic.Thedesignofthiscourseistodevelopacomprehensiveapplicationofthemulti-disciplinarytheory,knowledgeandskillstosolvethecomplexpracticalproblemsoftheproject,mainlyincludingthedesign,theanalysisanddemonstrationoftheexperimentalresearchproject,thesummaryoftheprinciple,thedevelopmentoftheschemeandthedeterminationofthematerial.Ithastrainedmetosetupthecorrectdesignthought,tobebravetopractice,tobebraveintheexplorationandinnovation,tomasterthemoderndesignmethodandtoadapttotheneedofthetrainingofthesociety.Keyword:MoldBallpointpenDesign目录.........................................................5............................................................5........................................7..............................................................7............................................................8..........................................................82..............................................................8............................................................9.........
