摘要注塑成型制品质量控制方面存在的困难主要来源于力学的复杂性和在温度、压力波动下材料行为的不可预测性,研究工艺参数对注塑制品质量的影响关系,建立工艺参数与制品质量之间的关系模型,并用DOE法对工艺进行仿真优化是注塑制品工艺优化的前提。本文选用半结晶型和无定型ABS两种材料,针对一维流动平板两个方向上的收缩、强度,熔接线强度、制品重量及沉降斑等质量指标进行了实验研究。研究了工艺参数对质量指标的影响及因素之间的交互作用。本文主要工作包括以下几方面:1工艺参数对制品质量的交互影响分析;2应用DOE法结合析因分析结果;3.CAE技术结合DOE法进行设计,并用MOLDFLOW进行仿真分析,为质量控制技术提供了工艺模型。关键词:注塑成型,正交实验,Moldflow,三维建模,工艺仿真优化,实验设计AbstractQualitycontrolofinjectionmoldingproducts,mainlydifficultiesfromthatexistinthecomplexityofprocessdynamicsandinthetemperatureandpressurefluctuationsunpredictablebehaviorofmaterials,ofprocessparametersonproductqualityofinjectionmoldingbetweentherelationship,DOEmethodwithsimulationandoptimizationtechnologyofinjectionmoldingproducts,processoptimizationisaprerequisite.Semi-crystallineandamorphousABSweusdinthispaper,Foraflatthattwo-dimensionalflowdirectionshrinkage,strength,weldlinestrength,weightandsinkmarksandotherproducts,thequalityindicatorsstudied.Inthispaper,includethefollowing:1.Processparametersonproductqualityofinteractionanalysis;2.ApplicationofDOEmethodwiththeresultsoffactorialanalysis;3.CAEdesignmethodcombinedwithDOE,SimulationandanalysiswithMOLDFLOW,qualitycontroltechnologyprovidesfortheprocessmodel.Keywords:InjectionMolding,Orthogonal,Moldflow,Three-dimensionalmodeling,Processsimulationandoptimization,designofexperiment.目录1.1引言..............................................................11.2注塑成型工艺过程简介.................................................11.3注塑成型工艺的发展趋势...............................................21.4注塑成型工艺优化国内外研究概况.......................................41.5本文主要工作内容及其意义.............................................62.注塑成型工艺参数影响性分析.................................82.1压力参数分析........................................................82.1.1注塑压力...............................................................................................................................................82.1.2保压压力...............................................................................................................................................82.1.3塑化压力(背压)..............................................................................................................................82.2温度参数分析........................................................92.2.1模具温度...............................................................................................................................................92.2.2熔体温度...............................................................................................................................................92.3时间参数分析.........................................................92.3.1注射时间...............................................................................................................................................92.3.2保压时间.............................................................................................................................................102.4注射速度分析........................................................103.基于DOE法的注塑成型仿真优化..............................113.1软件Moldflow以及正交实验助手的介绍.................................123.1.1moldflow软件简介............................................................................................................................123.1.2正交实验助手介绍............................................................................................................................123.2材料的选取及模型的导入..............................................143.3本次实验设计法的分析理论依据........................................173.3.1.实验基本参数取值范围的确定及输入.............................................................................................173.3.2.正交表的设置及数据生成.................................................................................................................183.3.3实验分析类型以及结果的选取.........................................................................................................193.4实验设计法的仿真优化过程............................................223.4.1Moldflow与正交表的数据结合分析...............................................................................................223.4.2实验数据的反馈与整合.....................................................................................................................284.模具设计..................................................314.1塑件用途及其性能要求................................................314.2注射量的计算........................................................314.3锁模力的计算........................................................314.4注塑机的选择及参数..................................................324.5分型面的确定.......................................................334.6浇注系统的设计.....................................................334.7成型零部件的设计与计算.............................................374.8推出机构设计.......................................................384.9标准模架的选取......................................................384.10开模行程的校核.....................................................394.11推出脱模机构设计..................................................404.12合模导向机构的设计...............................
