The water cooling system further comprises a plurality of cooling water channels 4, a water tank 2, a water distributor 3, a vacuum distributor 5 and a vacuum pump 6 which are arranged on the forming module 1, a plurality of water outlets 31 connected with the water inlet ends of the cooling water channels 4 are formed in the water distributor 3, and the vacuum distributor 5 is provided with a plurality of water inlets 51 connected with the water outlet ends of the cooling water channels 4.

As shown in fig. 1, the vacuum distributor 5 is connected to a vacuum pump 6, the water separator 3 is connected to the water tank 2, and the water separator 3 and the vacuum distributor 5 are installed at both sides of the molding module 1. The forming module 1 is provided with a plurality of mutually communicated drill holes which are distributed on the periphery of a die cavity of the forming module to form a cooling water path 4 surrounding the periphery of a cooling die cavity. The water outlets 31 of the water separator are connected to the water inlet ends 41 of the cooling water paths 4, and the water inlets 51 of the vacuum distributor are connected to the water outlet ends 42 of the cooling water paths 4. The water tank 2, the water separator 3, the cooling water channel 4, the vacuum distributor 5 and the vacuum pump 6 are communicated in sequence.
