圆盘卡盖的注塑模设计 摘要 当前圆盘卡盖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圆盘卡盖注塑模设计、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。本文设计的是一模一腔两板式模具，由于圆盘卡盖的特殊形状，无法直接脱模，需设置活动镶件分型机构，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，利用三维软件画出注件的三维图，并设计好浇注系统、开模方向，在确定无误之后，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。 通过采用组合式型芯，并在型芯块上设计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，圆盘卡盖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。 关键词：圆盘卡盖；注塑模；模架一模一腔;两板式模具 Abstract A lot of the disc covers i
