250克塑料注射成型机设计说明书

山东科技大学学士学位论文1摘要塑料注射成型机是一种能将塑料加热塑化，借助推进机构把熔化的塑料注入模具型腔内，经冷却、定型后形成制品的塑料成型加工设备。它能配置不同的模具，可一次成型外形复杂的制品，是塑料机械中主要机种之一。塑料注塑成型机有很多型式，液压式塑料成型机就是其中之一，其主要由合模机构，注射部件，液压传动及电气控制系统等几部分组成，而液压泵，液压缸、各种液压阀、电机、电气元件以及控制仪表是其中不可缺少的控制元件。塑料注射成型机以其成型周期短，对各种塑料的加工适用性强，尺寸较精确以及自动化程度高等优点，得到了广泛应用。关键词：塑料注射成型机、液压系统、液压泵、液压缸、液压阀山东科技大学学士学位论文2ABSTRACTTheplasticcastsshaperisonekindofheatinguptheplastictheplasticizing,poursintowiththeaidoftheadvancementorganizationthemeltingplasticinthemoldcavity,aftercooling,thestereotypiaformstheproducttheplastictotakeshapetheprocessingequipment.Itcandisposethedifferentmold,buttimetakesshapethecontourcomplexproduct,isintheplasticmachineryoneofmainaircrafttypes.Theplasticinjectiontakesshapealreadyhasverymanyforms.Thehydraulicpressuretypeplasticinjectionshaperisoneofthem,itmainlyhasgathersthemoldorganization,injectsthepart,thehydraulictransmissionandtheelectricitycontrolsystemandsoonseveralpartsofcompositions,butthehydraulicpump,thehydrauliccylinder,eachkindofhydraulicvalve,theelectricalmachinery,theelectricalpartaswellasthecontrolmeasuringapplianceareindispensablecontrolpart.Theplasticinjectionshapertakesshapethecyclequicklybyit,toeachkindofplasticprocessingcompatible,thesizeispreciseaswellastheautomaticityhighermerit,obtainedthewidespreaduse.Keyword:Plasticinjectionshaper,hydraulicsystem,hydraulicpump,hydrauliccylinder,hydraulicvalv山东科技大学学士学位论文3目录摘要........................................................................................................1ABSTRACT............................................................................................2目录........................................................................................................31绪论...................................................................................................51.1、塑料注射成型机概述.................................................................51.2、注射成型机的工作原理.............................................................61.3、技术要求及已知参数.................................................................71.3.1对液压系统的要求.............................................................81.3.2液压系统设计参数.............................................................82.250克塑料注射祝液压系统设计计算.....................................102.1液压执行元件载荷力和载荷转矩计算......................................102.2.液压系统主要参数计算...............................................................112.2.1初选系统工作压力............................................................112.2.2计算液压缸的主要结构尺寸...........................................122.2.3计算液压马达的排量.......................................................132.2.4计算液压执行元件实际工作压力...................................132.2.5计算液压执行元件实际所需流量...................................132.3.制定系统方案和拟定液压系统图..............................................142.3.1制定系统方案...................................................................142.3.2拟定液压系统图...............................................................152.3.3液压元件的选择与设计...................................................24山东科技大学学士学位论文42.4.液压系统性能验算......................................................................312.4.1验算回路中的压力损失...................................................312.4.2液压系统发热温升计算...................................................332.4.3冷却器的计算...................................................................363系统使用维护说明书.....................................................................383.1.注塑机温升过高五大危害........................................................383.2.注塑机-原理和模式..................................................................393.3.注塑机-维护..............................................................................413.4.预防性维修保养........................................................................413.4.1液压油量...........................................................................423.4.2液压油温度.......................................................................423.4.3液压油油质.......................................................................423.4.4滤油器清洗......................................................................433.4.5冷却器清洗.......................................................................433.5.注塑机电脑面板........................................................................433.5.1电气部分...........................................................................433.5.2机械部分..........................................................................453.6.油温过高....................................................................................463.7.噪音产生....................................................................................473.8.保养简表....................................................................................48设计分析.................................................................................................49设计心得.................................................................................................50致谢辞......................................................................................................51山东科技大学学士学位论文5参考书目...................
