Aluminum alloy semi-solid forming die

The invention provides an aluminum alloy semi-solid forming die. A lower mold is fixedly arranged in the middle of the top of the supporting base, a mold cavity is formed in the middle of the top of the lower mold, a first ejector rod assembly slidably penetrates through the left side of the bottom of the lower mold, a second ejector rod assembly slidably penetrates through the right side of the bottom of the lower mold, and a spiral cooling pipe assembly is fixedly arranged in the lower mold. A supporting column is fixedly arranged on the left side of the top of the supporting base. According to the aluminum alloy semi-solid forming mold, through mutual cooperation of the upper mold plate, the first lower push rod, the first ejector rod assembly and the second ejector rod assembly, rapid demolding is achieved; and the interior of the die cavity is efficiently cooled, the time needed for forming is shortened, and the overall machining efficiency is improved. 本发明提供一种铝合金半固态成型模具。所述支撑底座的顶部中间固定设置有下模具，所述下模具的顶部中间开设有
