摘要

采用纯铜压铸工艺、循环压射的方法测试了H13和3Cr2W8V两种热作钢模具在纯铜压铸上的使用寿命。结果表明

由于纯铜压铸温度高

H13钢和3Cr2W8V钢模具均出现了较大的热疲劳裂纹而导致报废

其在纯铜压铸上的使用寿命远远低于其在铝压铸上的寿命

H13钢模具寿命较3Cr2W8V钢模具高

但其寿命也只达到160模次。

Abstract

Service life of H13 and 3Cr2W8V hot working tool steel in die casting pure copper was analyzed. H13 steel mould and 3Cr2W8V steel mould are failure in die casting pure copper as a result of high temperature resulting in the occurrence of thermal fatigue crack with large size

so their service life in the die casting pure alloy is far lower than those in die casting aluminum alloy. Although service life of H13 steel is superior to that of 3Cr2W8V steel

it only reaches up to 160 cycles.
