The user can control the stamping part to drive the upper die downward to assemble with the lower die to stamp the material into a car cover.

[0004] However, because different types of upper and lower dies need to be replaced when producing different types of automobile covering parts, when using a crane to transport the upper or lower die, the hook of the crane needs to use a connecting rope such as a steel rope to connect the object to be lifted. Since the stamping part directly above the supporting platform will limit the movement of the hook and the connecting rope between the stamping part and the supporting platform, the user cannot use the crane to lift the upper and lower dies directly between the stamping part and the supporting platform.

[0005] Therefore, when replacing the mold, the user needs to first use a crane to lift the upper and lower molds to be replaced to the vicinity of the supporting platform, then manually lift the upper mold onto the supporting platform, then drive the stamping part close to the upper mold, and then use a long-handled wrench and bolts to fix the upper mold on the stamping part, then lift the lower mold onto the supporting platform, and finally manually adjust the position of the upper and lower molds, which makes it more laborious to replace the mold with existing stamping equipment.
