本科畢業(yè)設(shè)計(jì)(論文)題目：遙控器電池后蓋模具設(shè)計(jì)系別：機(jī)電信息系專業(yè)：機(jī)械設(shè)計(jì)制造及其自動(dòng)化班級：學(xué)生：學(xué)號：指導(dǎo)教師：2013年5月遙控器電池后蓋注塑模具設(shè)計(jì)摘要本文詳細(xì)介紹了遙控器電池后蓋注塑模具的設(shè)計(jì)，共分十四節(jié)，主要包括：塑件材料的分析與設(shè)計(jì)方案的論證；注塑機(jī)的選擇；模具結(jié)構(gòu)的設(shè)計(jì)；成型零件的設(shè)計(jì)；導(dǎo)向機(jī)構(gòu)的設(shè)計(jì)；脫模機(jī)構(gòu)的設(shè)計(jì)；側(cè)向分型與抽芯機(jī)構(gòu)的設(shè)計(jì)等。本次設(shè)計(jì)為一模兩腔，塑件材料選用了丙烯腈丁二烯苯乙烯共聚物（即工程材料ABS），澆口形式選用了側(cè)澆口，模具結(jié)構(gòu)為直接分型推桿推出機(jī)構(gòu)。通過以下計(jì)算和設(shè)計(jì)是可行的，并可以應(yīng)用到實(shí)際生產(chǎn)中。本次設(shè)計(jì)主要是對一種塑料遙控器電池后蓋進(jìn)行模具設(shè)計(jì)。本文先介紹了注射模具國內(nèi)外的發(fā)現(xiàn)狀況及發(fā)展趨勢，其次介紹了注射成型原理和工藝過程；根據(jù)塑件要求選擇合適的注塑機(jī)，進(jìn)而選擇合適的澆注系統(tǒng)與冷卻系統(tǒng)；通過計(jì)算，對導(dǎo)向機(jī)構(gòu)、脫模機(jī)構(gòu)和側(cè)向分形與抽芯機(jī)構(gòu)進(jìn)行設(shè)計(jì)。該模具的凸凹模均采用嵌入式的型腔和型芯，精度高，節(jié)省材料，改善了模具加工的工藝性，降低了模具的生產(chǎn)成本。該模具采用單分型面設(shè)計(jì)，通過滑塊和斜導(dǎo)柱實(shí)現(xiàn)開合模動(dòng)作，模具運(yùn)動(dòng)平穩(wěn)可靠。塑件能順利脫模，該模具總體結(jié)構(gòu)設(shè)計(jì)合理，模具的制造成本低。成型的殼體塑件質(zhì)量合格穩(wěn)定，使塑件質(zhì)量符合設(shè)計(jì)和使用要求。關(guān)鍵詞：遙控器電池后蓋；注塑模具；側(cè)抽芯機(jī)構(gòu)；導(dǎo)向機(jī)構(gòu)；脫模機(jī)構(gòu)TheDesignoftheTelecontrollerInjectionMoldAbstractThispaperintroducedthedesignoftelecontroller,andconsisted14parts.Mainlyincludeanalysisofplasticmaterialandargumentationofdesignproject；selectinginjectionmachine；devisingmoldstructure；devisingmoldingparts；devisingorientedframework；devisingstrippingframework；devisingsidepartingandpullingframework.Themoldisconsistedoftwocavities.Theplasticmaterialselectacrylonitrilebutadiene-styrenecopolymer(i.e.engineeringmaterialABS).Thesprueformchooseasidegate,diestructurefordirectclassification-pushrodpushingmechanism.Bythefollowingcalculationanddesignisfeasible,andcanbeappliedtopracticalproduction.Thedesignismainlyremotecontrolbatterycoverofaplasticmolddesign.Thispaperfirstdescribesthesituationanddevelopmenttrendoftheinjectionmoldfoundathomeandabroad,followedbyinjectionmoldingprincipleandprocess；plasticpartsrequiretheinjectionmoldingmachine,andthenselecttheappropriategatingsystemandcoolingsystem；,orientedagencies,strippingagenciesandlateralfractaldesigncore-pullingmechanism.Themoldpunchanddieareembeddedinthecavityandcore,highprecision,materialsavings,improvedmoldprocess,reducingthecostofproductionofthemold.Themoldwithasinglepartingsurfacedesign,moldopeningandclosingactionsliderandBevelPillar,themoldmovementissmoothandreliable.Plasticpartssmoothstrippingoverallstructureofthemolddesign,moldmanufacturingcostslow.Themoldingoftheplasticpartsofthehousingofacceptablequalityandstability,sothatthequalityofplasticpartscomplywiththedesignanduserequirements.KeyWords:telecontroller；InjectionMold；DevisingSideParting；DevisingOrientedFramework；PullingFramework主要符號表T額定鎖模力q模腔壓力K安全系數(shù)minH最小模具厚度maxH最大模具s塑件尺寸誤差maxS塑料的最大收縮率minS塑料的最小收縮率sL塑件尺寸S塑料的平均收縮率塑料的公差模具制造公差型腔許用變形量E型腔材料的彈性模量型腔材料的需用壓力脫模斜度f摩擦系數(shù)F脫模力推桿長度系數(shù)Q總脫模力應(yīng)力s屈服極限目錄1緒論.11.1題目背景.11.2題目國內(nèi)外相關(guān)研究情況.11.3中國與國外先進(jìn)技術(shù)的差距.21.4塑料模具發(fā)展走勢.22塑件材料分析與方案論證.42.1塑件材料的選擇及其結(jié)構(gòu)分析.42.2ABS的注射成型工藝.42.3塑件收縮率與模具尺寸的關(guān)系.62.4方案論證.73注射機(jī)的選擇.113.1確定零件的體積.113.2選擇注射機(jī)及注射機(jī)的主要參數(shù).113.2.1注射機(jī)的類型.113.2.2注射機(jī)的主要技術(shù)參數(shù).123.2.3注塑機(jī)的校核.134模具結(jié)構(gòu)設(shè)計(jì).154.1澆注系統(tǒng).154.1.1澆注系統(tǒng)的作用.154.1.2澆注系統(tǒng)布置.154.2澆注系統(tǒng)設(shè)計(jì).154.2.1澆口套的設(shè)計(jì)：.154.2.2冷料井設(shè)計(jì)
