I耳機(jī)塑料注塑模具設(shè)計(jì)摘要塑料工業(yè)是當(dāng)今世界上增長(zhǎng)最快的工業(yè)門類之一，而注塑模具是其中發(fā)展較快的種類，因此，研究注塑模具對(duì)了解塑料產(chǎn)品的生產(chǎn)過(guò)程和提高產(chǎn)品質(zhì)量有很大意義。注射模技術(shù)的不斷發(fā)展需要越來(lái)越多的工藝流程。注射成型過(guò)程中最重要的問(wèn)題是模具的正確設(shè)計(jì)。從根本上說(shuō)，注射模具包括澆口和澆注系統(tǒng)，另一部分是放置頂出系統(tǒng)。模具零件是在分型面被定位的。注射模具型腔選擇等設(shè)計(jì)計(jì)算要求掌握加工材料、注射機(jī)和模具等方面的準(zhǔn)確知識(shí)。模具的制造成本隨著型腔數(shù)目的增加而增加，而相關(guān)的加工費(fèi)用減少了。一個(gè)給定的模具零件的生產(chǎn)周期取決于壁厚、注射速度、收縮率、模內(nèi)材料的冷卻時(shí)間、冷卻的效能及必要的輔助時(shí)間，如壓力持續(xù)時(shí)間、排氣時(shí)間及延遲時(shí)間等。本設(shè)計(jì)介紹了注射成型的基本原理，特別是單分型面注射模具的結(jié)構(gòu)與工作原理，對(duì)注塑產(chǎn)品提出了基本的設(shè)計(jì)原則；詳細(xì)介紹了冷流道注射模具澆注系統(tǒng)、溫度調(diào)節(jié)系統(tǒng)和頂出系統(tǒng)的設(shè)計(jì)過(guò)程，通過(guò)本設(shè)計(jì)，可以對(duì)注塑模具有一個(gè)初步的認(rèn)識(shí)，注意到設(shè)計(jì)中的某些細(xì)節(jié)問(wèn)題，了解模具結(jié)構(gòu)及工作原理。關(guān)鍵詞：塑料模具，參數(shù)化，分型面，澆注系統(tǒng)，模具型腔。IITHEPLASTICINJECTMODLEDESIGNABSTRACTplasticindustryisintheworldgrowsnowoneofquickestindustryclasses,butcaststhemouldisdevelopmentquicktype,therefore,theresearchcaststhemoldtounderstandtheplasticproducttheproductionprocessandimprovestheproductqualitytohavetheverybigsignificance.Thecontinuingdevelopmentofinjectionmoldtechnologydemandsmoreandmoreoftheprocesses.Themostimportantproblemintheprocessofinjectionmoldingisundoubtedlythecorrectdesignofinjectionmold.Basicallytheinjectionmoldconsistsoftwohalves.Onemoldhalfcontainsthespruebushingandrunnersystem,theotherhalfhousestheejectionsystem.Themoldedpartislocatedatthepartingline.Tosetupacalculationconceivingthechoiceofcavitiesinaninjectionmoldrequiresaccurateknowledgeofthematrrialtobeprocessed,oftheinjection-moldingmachineandofthemolds.Themoldcostsincreasewiththerisingnumberofcavitiesandtherelativemachinecostsdecrease.Theproductiontimerequiredforagivenmoldedpartdependsonthewallthicknes,theinjectionspeed,therecoveryrate,thetimerequiredtocollthemoldedmaterial,thecoolingcapacityofthemoldandthenecessaryincidentaltimesuchasdurationofpressureholdingtime,ejectiontime,delaytime,ect.Thisdesignintroducedtheinjectiontakesshapethebasicprinciple,speciallysingleisdividedtheprofiletoinjectthemoldthestructureandtheprincipleofeork,tocasttheproducttoproposethebasicprincipleofdesign；Introductedindetailthecoldflodchannelinjectionevilspiritmoldpoursthesystem,thetemperaturecontralsystemandgoesagainstthesystemthedesignprocess,andhasgiventheexplanationtothemoldintensityrequest；Throughthisdesign,maytocastthemoldtohaveapreliminaryunderstanding,notesinthedesigncertaindetailquestion,understandsthemoldstructureandtheprincipleofwork；ThroughtothePROGRAMstudy,mayestablishthesimplecomponentsthecomponentsstorehouse,thuseffectiveenhancementeorkingIIIefficiency.KEYWORDS:Theplasticmold,theparameterization,inlays,dividestheprofileIV目錄前言.1第一章：制件的結(jié)構(gòu)與工藝性分析.21.1制件相關(guān)信息.21.2材料的相關(guān)性質(zhì).21.2.1基本特性.21.2.2主要用途.31.2.3成型特點(diǎn).31.3塑件的脫模斜度.31.4塑件的尺寸精度及表面質(zhì)量要求.4第二章：初選注射機(jī).52.1計(jì)算塑件體積和最大投影面積.52.2選擇壓力機(jī).52.3確定型腔數(shù)目.6第三章模具設(shè)計(jì).83.1型腔的分布設(shè)置.83.2分型面的確定.83.3澆口的確定原則.93.4澆注系統(tǒng)的確定.103.4.1主流道的設(shè)計(jì).103.4.2分流道的設(shè)計(jì).113.4.3冷料穴的設(shè)計(jì).123.4.4澆口的相關(guān)參數(shù)選擇.123.5成型零部件的結(jié)構(gòu)設(shè)計(jì).133.5.1型腔的結(jié)構(gòu)設(shè)計(jì).133.5.2型芯的結(jié)構(gòu)設(shè)計(jì).133.6模具成型零部件尺寸計(jì)算.143.5.1計(jì)算成型零部件尺寸要考慮的因素.143.5.2制件尺寸的公差轉(zhuǎn)換.153.5.3成型零部件尺寸計(jì)算.15V3.7模架的選用.173.7.1模架型號(hào)的確定.173.7.2模架具體尺寸的確定.183.8結(jié)構(gòu)零部件的設(shè)計(jì).193.8.1支承板的設(shè)計(jì).193.8.2墊塊的設(shè)計(jì).203.8.3定模座板和動(dòng)模座板的設(shè)計(jì).203.8.4導(dǎo)柱的設(shè)計(jì).203.8.5導(dǎo)套的設(shè)計(jì).213.8.6設(shè)計(jì)導(dǎo)柱導(dǎo)套需要注意的事項(xiàng).213.9推出機(jī)構(gòu)的設(shè)計(jì).223.9.1推桿的設(shè)計(jì).23第四章冷卻系統(tǒng)的設(shè)計(jì).254.1冷卻
