Delayed ejection thermal forming mold

The utility model discloses a thermal forming die with delayed ejection. The thermal forming die is suitable for controlling delayed ejection of a lower die pressing core. The utility model discloses a delayed ejection thermal forming die which comprises an upper die, a lower die, a control part and a delayed moving part. The upper die comprises an upper die frame, an upper die pressing core and a first driving element. The lower die comprises a lower die frame, at least two lower die pressing cores and at least two second driving elements. And the control part is arranged to control the first driving element and the second driving element to move. The delay moving part is arranged to control the output end of the second driving element to move in a delay mode, so that when the first driving element is controlled by the control part to move, the second driving element moves after being delayed for preset time. The problem that a traditional delay nitrogen cylinder is high in price is solved. 本申请公开了延时顶出的热成型模具，
