摘要
尾板是镁合金压铸机的重要部件,为三大板之一。其强度和刚度直接影响到压铸机的工作状况和铸件的品质。对3000T镁合金压铸机尾板在实际使用中出现的裂纹状态进行深入分析,讨论了产生裂纹的原因,并基于有限元方法,对尾板的静态、瞬态冲击以及疲劳强度进行了计算和分析,提出了改进现有设计的几种方案。得出的结论为提高压铸机在生产中的安全性能提供了重要数据,对压铸机的改进设计具有重要的参考意义。
The clamping moulding board is a strength component one of the three main boards. It＇s intensity and rigidity have some s of magnesium alloy casting machine, ant effects on the running af machine and the quality of castings. Crack failure of the clamping moulding board during service has been analyzed. Then the optimum design are carried out according to the results of finite element analysis. Several design schemes are compared. The concluded results can provide the important data to estimate the casting machine＇s safety, and have important meaning on the optimum design of casting machine.
