A cavity is formed between the upper, lower, and middle molds. A pouring port is provided in the center of the upper mold, corresponding to the cavity. The bathtub is molded using the upper, lower, and middle molds. Therefore, when demolding the finished bathtub, the upper mold is first demolded, then the middle mold, and finally the product is separated from the lower mold.

[0026] Two chutes 5 are provided on the top surface of the machine tool 1, and the chutes 5 are evenly set up at the two end edges of the machine tool 1. The bottom mold 2 is installed on the machine tool 1, and the two sliders 8 are installed in the chutes 5. After installation, the four pulleys 7 on the bottom surfaces of the two sliders 8 will all press against the bottom surfaces of the two chutes 5, so that the sliders 8 can move along the chutes 5. When moving, the friction between the sliders 8 and the chutes 5 is reduced by the pulleys 7. A support frame 12 is welded on the top surface of the machine tool 1.
