Therefore, the water vapor carried by the airflow is discharged outdoors to prevent the water vapor from entering the room through the second chute 20 to increase the humidity. The airflow will accelerate the evaporation of warm water, speed up the cooling of the warm water, and accelerate the natural cooling of the upper mold and the lower mold.

[0032] The two clamping assemblies 6 each include a heat insulation frame 61 and a heat insulation seat 65. The two heat insulation frames 61 are respectively fixed on the inner walls of the two through grooves. The inner walls of the two heat insulation frames 61 are rotatably connected with lifting screws 62 through sealed bearings. The surfaces of the two lifting screws 62 are threadedly connected with lifting blocks 63 that slide with the inner walls of the heat insulation frames 61 through screw nuts. One side of the two lifting blocks 63 is fixed with a pressing block 64. The surfaces of the two pressing blocks 64 are provided with grooves. Each pressing block 64 has four grooves, which are used to reduce the weight of the pressing blocks 64.

The translation motor 16 drives the bidirectional screw rod 3 to rotate, and the bidirectional screw rod 3 drives the two clamping blocks 5 to move through the two dovetail blocks 4, so as to clamp the upper mold and the lower mold after the mold is closed. Then, the two lifting motors 66 are started, and the lifting motor 66 drives the lifting screw rod 62 to rotate, and the lifting screw rod 62 drives the lifting block 63 and the pressing block 64 to move downward, and the pressing block 64 presses the upper mold to consolidate the mold closing of the upper mold and the lower mold, and finally the hot press is started for pressure melting molding;

[0034] After the pressure melting molding, the micro submersible pump 12 is started. The cold water tank 9 contains cold water. The micro submersible pump 12 pumps the cold water into the cooling pipe 8 through the cold water pipe 11. The cold water exchanges heat with the clamp block 5 when flowing through the cooling pipe 8, thereby reducing the temperature of the clamp block 5. The clamp block 5 clamps the upper mold and the lower mold corresponding to the hot press. Therefore, the upper mold and the lower mold are cooled by the low-temperature clamp block 5, thereby improving the cooling efficiency.

[0035] Furthermore, impurities in the cold water are filtered out by the cooperation of the protective cover 13 and the filter screen 15 to prevent the impurities from being sucked into the micro submersible pump 12 and to prevent the micro submersible pump 12 from being blocked. The moving protective cover 13 drives the filter screen 15 to move, and the filter screen 15 will rub against the cleaning brush layer 73, thereby cleaning impurities on the surface of the filter screen 15 and ensuring the water permeability of the filter screen 15. Use a screwdriver to remove the screws on the surface of the baffle 72. After removing the screws, pass the screwdriver through the auxiliary pulling tube 74, and use the screwdriver to drive the moving seat 71 to move upward, and remove the moving seat 71 and the cleaning brush layer 73 from the through groove for easy maintenance.
