摘　　要：根据锤式破碎机锤头的结构和使用要求,结合高锰钢材料的特点,进行了锤式破碎机锤头挤压铸造模具设计。液锻成形设备采用专用挤压铸造机,其上挤缸最大挤压力为12500kN。模具总体方案为间接成形,水平分模,1模3件,利用蝶簧与柱簧实现浮动模成形,充分利用锁模缸的能力,采用下缸上行间接顶件。According to the structure and operating requirements of hammer head used in hammer crusher,and the characteristics of high manganese steel,the mold design by Squeeze casting is performed.Specialized former for squeeze casting is used here,and its maximal extrusion force is 12 500 kN.The design scheme is indirect forming,and spring association is used for locking the die,while drip molding is pushed out indirectly by the subjacent fluid cylinder.It is proved in productive practice that:It is feasible to produce hammer by using this set of mold.
