低压铸造新型模具性能及寿命提升研究

Research on Enhancing Performance and Life of Low-pressure Casting Molds

从低压铸造过程中热应力形成的角度分析了简化模型的热应力影响因素,采用提高材料热导率和使用耐高温而又绝热材料的方法把液态金属与铸型隔开,并结合模具设计和保养,利用VSR法消除应力达到提升金属型模具寿命和性能的目的。

From the form of the thermal stress of molds in the low-pressure casting process to analyze the effect factor of thermal stress in the simplified model, improving the thermal conductivity and using high temperature thermal insulation material to separate the liquid metal from the molds, combining with the mold design and maintenance, and using the VSR to eliminate the stress, can improve the life and performance, of metal molds.
