铝合金定位座体的铸造工艺设计

Process Design of Positioning Seat Castings of Aluminum Alloy

通过对定位座体不同工艺方案的优缺点对比,采用底注、三箱造型、大法兰朝下、加大底部芯头;采用顶冒口、变壁冷铁、平面冷铁与加大横浇道截面尺寸,实现铸件自下而上的顺序凝固,所生产的铸件一次交检合格,并且提高了工艺出品率和劳动生产率。

The advantages and disadvantages of different process schemes for positioning seat body castings were compared. Using the process of bottom gating, three box moulding, large flange down and large bottom core head with top riser, mutative-wall cold iron, planar cold iron and large runner section size to realize the casting solidification sequence from bottom to top, the qualified castings can be produced, and the process yield and productivity are improved.
