路由器的外壳设计摘要一个给定过程的有效模拟需要来自于应用领域(自然科学或工程)、数学(分析和数值数学)及计算机科学的知识。然而，所有这些技术在复杂应用中的使用并不是太容易。这是因为组合所有这些方法需要巨大的复杂性及交叉学科的知识。最终软件的实现变得越来越复杂，以致于超出了一个人能够管理的范围。一些非常成功的解偏微分方程的技术，特别是自适应网格加密（adaptivemeshrefinement）和多重网格方法在过去的十年中已被数学家研究，同时随着计算机技术的巨大进展，特别是大型并行计算机的开发带来了许多新的可能。UGNX是一个在二和三维空间无结构网格上使用自适应多重网格方法开发的一个灵活的数值求解偏微分方程的软件工具。其设计思想足够灵活地支持多种离散方案。因此软件可对许多不同的应用再利用。作为塑料制品的主要生产基础工艺装备的塑料模具，在国民经济中占有重要的地位，模具技术也已成为衡量一个国家产品制造水平的重要标志之一。进入21世纪以来，我国在模具行业发展迅猛。模具行业为推动我国的经济生活各领域的发展做出巨大贡献。随着我国进入“十二五”快速发展时期，在机械、汽车、家电、电子信息和建筑建材等领域对塑料模具的强烈市场需求推动下，塑料模具的发展前景一片光明。其中复杂、高精度、多功能复合型模具成为未来模具行业发展的重点。我国从改革开放开始，对国外先进技术的消化吸收，特别是计算机技术在整个制造领域的成功应用更是大大地推动了模具行业的飞速发展。近年来我国在模具行业取得长足进步，新材料、新工艺、先进加工设备不断出现。模具零件的标准化、专业化和商品化已达到较高的水平。如今世界模具工业的发展速度超过了新兴的电子工业，已实现了模具专业化、标准化和商业化，因而深受赞誉。模具又因其生产效率高、产品质量好、材料消耗低、生产成本低而获得广泛应用，与其他加工制造业所无法比拟的。当然近年来，我国模具行业一直保持着良好的发展，已经驶入发展快车道。尤其我国模具工业在政府十分重视及关怀下，并提出相应的优惠政策进行模具技术开发，在模具工业中大量采用先进技术和设备，努力提高模具设计和制造水平，取得显著的经济效益。关键词：精度；塑料模；AbstractAgiveneffectivesimulationoftheprocessofneedfromtheapplicationdomain(naturalscienceorengineering),mathematics(analysisandnumericalmathematicsandcomputerscienceknowledge.Useofallofthesetechnologiesincomplexapplications,however,isnoteasy.Thisisbecausethecombinationofallthesemethodsneedgreatcomplexityandinterdisciplinaryknowledge.Therealizationofthefinalsoftwareisbecomingmoreandmorecomplex,thatisbeyondthescopeofapersoncanmanage.Someverysuccessfulsolutionofpartialdifferentialequationsoftechnology,especiallytheadaptivemeshrefinement(adaptivemeshrefinement)andmultiplegridmethodinthepastdecadehasbeenthemathematicians,atthesametimewiththehugeprogressofcomputertechnology,especiallythedevelopmentoflarge-scaleparallelcomputerbroughtalotofnewpossibilities.UGNXisagridintwoandthreedimensionalspacestructureusingadaptivemultigridmethodtodevelopaflexiblesoftwaretoolforthenumericalsolutionofpartialdifferentialequation.Itsdesignideaisflexibleenoughtosupportavarietyofdiscretescheme.Sothesoftwarecanbereusedformanydifferentapplications.Basedprocessequipmentasthemainproductionofplasticproductsofplasticmold,occupiesanimportantpositioninnationaleconomy,mouldtechnologyhasbecomeameasureofacountryalsooneoftheimportantsymbolofthelevelsofproductmanufacturing.Sincethe21stcentury,inthemoldindustrydevelopingrapidlyinourcountry.Moldindustryinordertopromoteourcountryagreatcontributiontothedevelopmentofeconomiclifeinallareas.Withtherapiddevelopmentintothe\twelfthfive-year\period,inmachinery,automobiles,homeappliances,electronicinformation,andconstructionbuildingmaterialsinareassuchasthestrongmarketdemandforplasticmould,plasticmoulddevelopmentprospectisbright.Thecomplex,high-precision,multi-functionalcompositediebecomethekeypointofthedevelopmentofthemouldindustryinthefuture.SincereformandopeningupinChina,thedigestionandabsorptionofforeignadvancedtechnology,especiallythesuccessfulapplicationofcomputertechnologyinthewholemanufacturingbutalsogreatlypromotetherapiddevelopmentofmoldindustry.Inrecentyears,greatachievementsinthemoldindustryinourcountry,newmaterial,newtechnology,advancedprocessingequipmentappearconstantly.Mouldpartsstandardization,specializationandcommercializationhasreachedahigherlevel.Nowtheworlddevelopmentofmoldindustryatafasterratethantheemergingelectronicindustry,hasrealizedthemoldspecialization,standardizationandcommercialization,andpraise.Mouldandbecauseofitshighproductionefficiency,productqualityisgood,lowmaterialconsumption,lowproductioncostandwideapplication,andotherprocessingmanufacturing.,ofcourse,inrecentyears,mouldindustryhasmaintainedagooddevelopmentinourcountry,hasbeenindevelopmentfastlane.Especiallymouldindustryinourcountryunderthegovernmentattachesgreatimportanceandconcern,andputsforwardthecorrespondingpreferentialpoliciesformoldtechnologydevelopment,inthemoldindustryintheuseofadvancedtechnologyandequipment,effortstoimprovethelevelofmolddesignandmanufacturing,hasmadesignificanteconomicbenefits.目录摘要……………………………………………………………‥…………2Abstract……………………………………………………………‥……………3引言……………………………………………………………‥…………71塑料模具及塑料模具行业……………………………………………………………………81.1塑料模具简介……………………………………………………………………81.2塑料模具行业的现状及发展方向………………………………………………82注塑成型工艺与设备………………………………………………………………………112.1注塑模的组成及各部分作用………………………………………………………112.2注塑成型过程………………………………………………………………………122.3注塑机………………………………………………………………………………133模具分析与设计……………………………………………………………………………143.1设计任务要求………………………………………………………………………………143.2塑件介绍及塑件材料………………………………………………………………………153.2.1塑件介绍……………………………………………………………………………153.2.2塑件材料分析介绍…………………………………………………………………153.3分型面选择…………………………………………………………………………………163.4型腔布置方案………………………………………………………………………………173.5注塑机的选择………………………………………………………………………………173.6注塑机参数的校核…………………………………………………………………………183.6.1最大注射量校核……………………………………………………………………183.6.2锁模力校核…………………………………………………………………………193.6.3模具闭合高度校核……………………………………………………………………203.6.4开模行程校核………………………………………………………………………203.7模具浇注系统设计和浇口的设计…………………………………………………………213.7.1主流道的设计………………………………………………………………………213.7.2分流道的设计………………………………………………………………………223.7.3浇口的设计…………………………………………………………………………223.8合模导向机构和定位机构…………………………………………………………………233.8.1导向机构的总体设计………………………………………………………………233.8.2导柱设计…………
