基于UG的饮水杯模具设计
摘要
当前饮水杯注塑成型工艺方法很多,为了进一步提高生产效率,节约生产成本,本文在现有的注塑成型工艺冷却方面做了进一步改进,选择在型芯上开设冷却水道,希望缩短冷却过程,从而提高生产效率。
本文主要介绍了经过优化型芯冷却系统后的饮水杯注塑模设计、塑料成形工艺以及注塑的过程,也对注塑机也进行了一些简单的介绍。主要设计过程有:塑料制品的工艺分析,型腔数目的确定,型芯冷却系统的设计,注塑机的选择以及模具的结构设计。本文设计的是一模两腔三板式模具,由于饮水杯的特殊形状,无法直接脱模,需设置侧面分型机构,本套模具是通过斜导柱进行侧面分型,本文对模具的各部分零件进行了设计与计算。在完成了一系列计算和构想之后,利用UG6.0画出注件的三维图,并设计好浇注系统、开模方向,然后进行开模仿真,在确定无误之后,利用EMX7.0设计模架,在完成模架设计之后,利用装配方法把整套模具完成整体设计并导出总装配图和爆炸图。
通过采用组合式型芯,并在型芯块上设计螺旋状冷却水道的冷却系统措施后,注塑过程中注件得到了良好的散热,提高了注件生产效率。在现有的工艺上做了改善之后,饮水杯的注塑过程大大缩短,既提高了生产效率,同时也节约了生产成本。
