摘　　要：货车机架铸件采用酯硬化砂机械造型方法 ,造型制芯使用很多外冷铁。冷铁在造型过程中捂置容易移位,加上硬化起模,移位的冷铁修复难度大。为此,决定在施放外冷铁的模样上加装磁铁,利用磁铁吸附冷铁,保证冷铁位置。Truck frame castings uses the modeling method of ester hardened sand machinery,molding core makes use of many external chill. Chiller is easy to shift when covered in molding process.Hardening die plus,it is very difficult to repair the shift. To this end, we decided to add magnets in the external chill appearance, making magnets adsorb chiller to guarantee the position of chiller.
