摘　　要：根据印刷油路板的结构特点,对其压铸工艺进行了设计,通过ProCAST专业分析软件对其压铸充型凝固过程进行了数值模拟,模拟结果显示该压铸工艺效果良好。基于该压铸工艺,对其压铸模具进行了设计。为达到充分地排气效果且便于模具的机械加工,模具以油路板上端面为分型面,铸件左右外侧壁面依靠定模镶块成形,上下外侧壁面依靠侧型芯成形,而内腔成形分配在动模侧。该模具结构紧凑,整体设计合理。According to the structure characteristics of the oil circuit board,the die casting process was designed,the mold filling and solidification process of die casting were simulated by using ProCAST professional analysis software.The simulation results show that the die casting process is entirely adequate and efficient.Based on the die casting process,the die casting die was designed.In order to achieve sufficient exhaust effect and facilitate the machining of the die,the upper end face of the oil circuit board is used as the parting surface,the left and right outer walls of the casting are formed by the fixed die insert,the upper and lower outer walls are formed by the side core,and the inner cavity is distributed on the moving die side.The structure and overall design of the die are reasonable.
