It should be noted that three jacking assemblies 50 are installed in one embodiment of the present invention, wherein the top plate 513 of the jacking member 51 is adapted to the shape of the stamping die 40 above the top plate 513, so that the top plate 513 can better support the stamped workpiece 22 during stamping and can directly eject the stamped workpiece 22 out of the die core 21 after stamping.

Meanwhile, the movement direction of the connecting rod 512 can be guided by the mounting hole in the top wall of the mounting cavity 23, wherein the elastic force applied to the baffle 511 by the elastic element 52 is the same as the axial direction of the connecting rod 512, so that the connecting rod 512 can move along the axial direction thereof to drive the top plate 513 to move, and thus, the top plate 513 can be ensured to eject the punching workpiece 22 along the axial direction of the connecting rod 512.
