中文摘要：

鉴于现有A13型后减振器的胀包模具完成胀包后只有自动退出内模动作,无外模退开动作,造成胀包后的工件被卡在胀包限位套上,取出非常困难.针对这些不足,通过对自动脱料机构进行优化设计,达到胀包后能轻松取下工件,以降低劳动强度和提高生产效率的目的.具体的实施效果也表明了新设计方案改进的合理性和可行性.

英文摘要：

The existing bulging die can only be withdrawn automatically from the internal mold after the expansion, and there is no withdrawing action of the external mold, namely, the die lacks the process of releasing or releasing the work piece, which causes the work piece stuck in the expansion pack limit after being expanded. In this paper, a solution is provided for the mentioned problems. Using the presented design, the work piece can be easily taken down after the expansion, and the operator-intervention can be reduced and the production efficiency is improved accordingly.
