陶瓷模具模芯通常采用 Cr12MoV制做，强度高，耐磨性良好。正常情况下，其使用寿命为 35～ 40万次。模芯的刃口部分由于受到坯料微粒的磨损，并承受一定的压力和冲击力，很容易损坏。失效形式主要为刃口部位磨损和由疲劳或碰撞模具衬板导致的刃口崩裂。若失效后直接报废换用新 Ceramic mold core is usually made of Cr12MoV, high strength, good wear resistance. Under normal circumstances, the service life of 35 to 40 million times. The edge of the mold core due to the wear of the blank particles, and to withstand some pressure and impact, it is easy to damage. Failure mainly in the form of wear and tear on the edge of the blade caused by fatigue or impact caused by the die-edge crack. If the failure of direct retirement for new use
