摘要
轴销形嵌件在压铸时,嵌件出现的表面飞边、划伤和尺寸超差的缺陷,在采用压紧嵌件的紧固销和弹簧后,消除了嵌件表面出现的飞边。在把模具安装嵌件的孔做出起模斜度,使嵌件的有效使用部分与模具孔不直接接触时,消除了嵌件表面拉伤的痕迹。为防止嵌件自动掉落下来,在压铸模具里设置磁铁后,可将铁质嵌件牢牢地吸附固定在模具里。
There exists surface flash,scratch and size over-tolerance on the die casting pin-shaped insert.Surface flash on the insert can be eliminated by using fast-pin and spring for pressing insert.Scratch on the insert surface can be avoided by setting drafting angle at hole for assembling insert in the mould to make the un-direct contact of effectively working position of the insert with hole at the mould.To prevent the insert from the mould automatically,magnetic iron was set in die casting die to ensure the fixation of iron insert in the mould.
