对4Cr5MoSiV钢质锻模挤压铸造试验进行了简单介绍 ,对所用模具结构的改进及运用进行了说明 ,实现了在一定试验条件下靠压机横梁一次回程中的连续三步脱模。最后说明了模具使用时应注意的问题
The squeeze casting experiment of 4Cr5MoSiV steel forging is introduced briefly. The improvement and application of the mold structure are described. The three-step demolding of the cross beam of the press under a certain test condition is achieved. Finally, the use of mold should pay attention to the problem
