摘　　要：大型压铸机在使用时由于其长期处于循环压铸状态,压射室温度过高,压射室和冲头易出现抱死故障,导致压射室使用寿命降低。因此文中针对压射室的结构进行优化,设置水路冷却结构对压射室进行降温,采用数值模拟和试验验证相结合的方法,采用SolidWorks软件进行三维建模,ProCAST软件进行仿真分析,研究冷却水参数对压射室冷却效果的影响,仿真结果表明:压射室的冷却水进出口水温控制在10~15℃之间较为合理,冷却水流速选择0.5 m/s或0.7 m/s较合适。When the large-scale die-casting machine is put into use,it is in a cyclic die-casting state for a long time,and the temperature in the injection chamber is too high.As a result,the injection chamber and the punch lock up,and the injection chamber’s service life is shortened.Therefore,in this article,the injection chamber’s structure is optimized;a water-cooling channel is set up to cool the injection chamber;the numerical simulation method is combined with experimental verification.Solidworks is used for 3D modeling and ProCAST is used for simulation analysis,so as to work out the influence of the parameters of the cooling water on the cooling effect of the injection chamber.The results show that it is reasonable to control the cooling wa-ter’s temperature within the range of 10~15℃,and the cooling water’s flow rate of 0.5 m∕s or 0.7 m∕s is proper.
