1、毕业设计(论文)板(框)类制品叠层式注射模具设计DESIGN OF STACK INJECTION MOULDPRODUCTS FOR FRAME学生姓名 学院名称专业名称 机械设计制造及其自动化指导教师 摘要本论文设计了仪器外壳的叠层式热流道模具结构。该模具有2层,每层8个型腔,一次可成型16个产品,该模具是普通注射成型产量的2倍,大大提高生产力。本次模具设计采用的是无流道凝料浇筑系统,不考虑浇道的凝料脱出,减少了分型面,并缩短了成型周期,降低了整个生产成本。而且还采用了齿轮齿条开模机构,在确保俩层型腔同时开模又比较经济。使热流道板的热胀变形问题和浇口的平衡问题有一个很好的解决,基本确保同时
2、充模和充模的稳定可靠性。该模具还采用闭合式喷嘴和闭合式主流道杯,解决了浇口和主流道始端的流涎问题,它采用热电偶控制喷嘴温度和流道板温度。在设计中,为减少热传导热损失。在流道板和型腔板之间采用空气隔热,并加隔热垫,从而降低模具和流道板之间的接触面积,并发挥了支撑热流道板的作用。喷嘴和主流道杯均采用隔热套隔热。关键词热流道;叠层式模具;浇口平衡;防流涎右键另存CAD图纸:6型腔板Al.dwg7制件A4.dwgAbstractThis design introduces the mould structure of instrument of outer cover, which has piles
