When one of the sprockets 10 rotates, one of the sprockets 10 will drive the other sprockets 10 to rotate in the movable groove 9 through the chain 11. When multiple sprockets 10 rotate, multiple first threaded rods 5 will be respectively moved upward by the action of multiple chain 11 threads, so that the multiple first threaded rods 5 drive the lifting plate 3 to move upward, so that the lifting plate 3 lifts the plastic part formed in the inner cavity of the lower mold 2, ensuring that the user can quickly take out the hot-pressed plastic part. After the hot-pressed part is taken out, the user uses his hand to lift it up. Rotate the rotating rod 7 in the opposite direction, so that the rotating rod 7 drives the second bevel gear 14 to rotate in the gear groove 12 in the opposite direction. When the second bevel gear 14 rotates in the opposite direction, the second bevel gear 14 will drive the first bevel gear 13 to rotate in the opposite direction in the gear groove 12, so that the first bevel gear 13 drives one of the sprocket wheels 10 to rotate in the opposite direction in the movable groove 9. When one of the sprocket wheels 10 rotates in the opposite direction, one of the sprocket wheels 10 will drive the other sprocket wheels 10 to rotate in the opposite direction in the movable groove 9 through the chain 11. When multiple sprocket wheels 10 rotate in the opposite direction, multiple first threaded rods 5 will be respectively moved downward by the action of multiple chain 11 threads, so that multiple first threaded rods 5 drive the lifting plate 3 to move downward. When the lifting plate 3 moves to a suitable position, the lifting plate 3 is lifted. The lowering plate 3 will move to its original position, and then the user will slide the threaded sleeve 19 in the opposite direction by hand, so that the threaded sleeve 19 drives the plug 17 to slide in the opposite direction in the second slide groove 15 through the second threaded rod 18, and at the same time, the second threaded rod 18 will slide in the opposite direction in the through groove 16, and when the plug 17 moves to the appropriate position, one end of the plug 17 will be inserted into the rotating rod 7 from the outside, and then the user will rotate the threaded sleeve 19 in the opposite direction by hand, so that the threaded sleeve 19 is moved toward the direction of the fixed block 8 by the action of the thread of the second threaded rod 18, and when the threaded sleeve 19 moves to the appropriate position, the threaded sleeve 19 will fix the plug 17 in the second slide groove 15 and cannot move, thereby ensuring that the rotating rod 7 can be fixed and preventing the rotating rod 7 from rotating due to external influences.
