s1, firstly, introducing water into a water storage tank (2), selecting a mold (13) with a corresponding model according to requirements, then fixing the two molds (13) on a first water passage (7) and a second water passage (10) respectively by using a second bolt (14), closing the two molds (13) together, injecting raw materials between the two molds (13), enabling the water in the water storage tank (2) to circularly flow in the first water passage (7), the second water passage (10) and a backflow pipeline (12) under the action of a water pump (11), and cooling the molds by using a heat conducting sheet (15) in a matching way so as to accelerate the forming speed of the raw materials;
s2, in the process of recycling the water in the water storage tank (2), a first heat dissipation fan (502) can be used for carrying out heat dissipation treatment on the water in the water storage tank (2), so that the water in the water storage tank (2) can be kept in a low-temperature state for a long time;
s3, after the molding treatment of the raw materials is completed, the two molds (13) are separated, meanwhile, the pushing block (1702) moves under the extending action of the second electric telescopic rod (1701), auxiliary demolding is facilitated, the molded materials finally fall onto the conveyor belt device (19), and in the process that the materials move backwards under the operation action of the conveyor belt device (19), the second heat dissipation fan (2002) blows downwards, so that the cooling treatment of the materials is facilitated.
