[0028] First, take out the upper mold 2 and the lower mold 3, align the moving block 7 below the upper mold 2 with the card slot on the lower mold 3 and press it down, so that the second spring 8 inside the moving block 7 drives the card block 9 to adjust and engage with the protrusion in front of the stopper 10 and the fixed rod 11, and the mold assembly is completed. When it is necessary to separate the upper mold 2 and the lower mold 3, hold the upper mold 2 and press it downward, so that the moving block 7 presses the lower moving plate 13 downward, and the third spring 14 below contracts. At this time, the card blocks 9 on both sides of the moving block 7 slide under the stopper 10, release the upper mold 2, and push the upper moving plate 13 and the moving block 7 upward through the third spring 14, so that the card block 9 drives the stopper 10 to slide to the top on the fixed rod 11, and the upper mold 2 and the lower mold 3 can be separated.
