[0031] By starting the heating plate 3, the mold groove 201 area opposite to the heating plate 3 is preheated. After the preheating is completed, the driving motor 1 drives the turntable 2 204 and the connecting plate 205 to rotate counterclockwise, so that the cylindrical block enters the inside of the slot, and moves inside the slot through the cylindrical block, and then drives the turntable 1 203 to drive the connecting rod 202 connected to the lower mold 2 to rotate 90 degrees inside the base 1, and then the preheated mold groove 201 is rotated to the bottom of the upper mold 101, and then the mold is placed in the preheated mold groove 201, and the hydraulic rod drives the upper mold 101 to hot press the mold.
