PAGE\*MERGEFORMAT29摘要本文介绍了注射模具的特点及发展趋势,叙述了塑料塑料盆注射模具设计与计算的详细过程,介绍了该塑件的成型工艺、注射模具的结构特点与工作过程,阐述了在注射模设计中应注意的事项。在对塑料塑料盆的模具设计过程中,本设计主要设计要点如下:塑件的设计比较的合理;分型面的选择有利于塑件成型;脱模机构的设计不但结构简单,而且脱模动作稳定可靠;进浇口的选择不影响塑件外观,而且保证塑件充填均匀;冷却水道的设计使模具效率达到最高,保证塑件质量要求;在设计的过程中借用分析软件如CAD等使设计更合理、更有效;大量使用标准件,使模具制作成本大大降低;本模具设计最关键的一点就是设计已达到实际生产的要求。关键词:塑料塑料盆,注射模,分型面,侧抽芯,脱模机构。abstractThecharacteristicsanddevelopmentsofinjectionmouldwereintroducedinthispaper.Thedesigningandcalculatingofinjectionmouldforthebackofelectronicclockwerestatedindetail.Theformingprocessoftheproductandthestructurecharacteristicsaswellasworkingprocessoftheinjectionmouldwereintroduced.Thepointsmustbepaidattentiontointhedesignoftheinjectionmouldforthepartwithlifterswerestated.Intheprocessofthedesigningoftheinjectionmouldforelectronicclockreceiver,peopleshouldpayattentiontoseveralsuggestions:theplasticshouldbedesignedasreasonableaspossible.Theselectionofthesub-typepartsarebeneficialtomoldthepartsofplastic.Thedesignofthestructureofdrawingofpatternisnotonlysimplebutalsothemovementshouldbestableandreliable.TheselectionofJinrunnershouldensuretofilltheplasticequallyundertheprerequisiteofnotinfluencingtheappearanceoftheplastic.Thedesignofcoolingpenstockshouldmaketherateofproductionreachtothetopmost,andensureanyinfluencetodonothingtotheequalityoftheplastic.Meanwhile,intheprocessofdesigning,wecanuseanalysissoft,suchasCAM,tomakethedesignbeenmorereasonableandefficient.Makingfulluseoflargeamountsofstandardpieceswillreducethecostofmoldplasticfacture.Thekeypointofthedesignofmoldplastichavereachedtherequestoftherealproduction.Keywords:Plasticinjectionmould,plasticbasin,thepartingsurface,thesidecorepulling,demouldingmechanism.目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc416262738"摘要PAGEREF_Toc416262738\h1HYPERLINK\l"_Toc416262739"abstractPAGEREF_Toc416262739\h2HYPERLINK\l"_Toc416262740"目录PAGEREF_Toc416262740\h3HYPERLINK\l"_Toc416262741"前言PAGEREF_Toc416262741\h5HYPERLINK\l"_Toc4
