补充资料：抽芯成型高差大的滑块多级锁紧结构
在压铸模设计中, 常常会遇到同一抽芯而各成型高度相差较大的零件, 如果采用斜拉杆或弯销抽芯, 习惯上采取的措施是增加滑块的高度,以满足滑块的退位空间,其结果是滑块的重量增加,模框的强度降低。
图1 是汽车油泵调速器前壳压铸件示意图, Ⅰ- Ⅰ分型面需用抽芯才能完成脱模,其最低抽芯高度Hmin 为17mm, 最大抽芯高度Hmax为45mm, 为了保证滑块有足够的退位空间而不发生自锁, 滑块的高度必须大于或等于45mm。为避免抽芯距离过大造成滑块体积增加, 在设计中采用了局部增高多级锁紧结构,如图2 所示。P 是高于17mm低于45mm的面,N是高于45mm的面,M面是与N面同高且保证N 面受力平衡的辅助结构。α为抽芯角,β1 、β2 为锁紧角,β1 、β2 不仅具有锁紧作用,而且在开模抽芯时还具有让位的作用,所以β1 、β2 必须大于α, 而且β2 应大于β1 , 否则开模时, 滑块会出现自锁。锁紧角β2 也可以等于β1 , 但由于制造时有误差, 如果误差大, 则β1和β2 形成的锁紧面会出现干涉。在压铸件调速器前壳模具设计中, α取23°, β1 取26°, β2取30°,实现了安全生产。
总之, 对于那些抽芯高度相差大的滑块,采用多级锁紧结构,对减小滑块的重量、延长模具寿命,节约模具材料具有重要的作用。
