NOVELTY - The utility model claims a circulating cooling box of die casting machine, comprising a cooling box, a cooling box, a copper plate; a radiating fin and a fan; two ends of the cooling box are equipped with a cooling box through a bolt; two ends of inner wall of the cooling box are embedded and welded with a copper plate; the cooling box and two ends of the cooling box are fixedly welded with radiating fins; a graphene plate is embedded between the radiating fin and the copper plate; the cooling box is alternately distributed with a separating copper plate; between the separating copper plate is formed with an S-shaped water flow passage; the separating copper plate is respectively with the corresponding position of the copper plate welding. exhausting air in the cooling box by the fan; the outside air is accelerated to flow into the cooling box through the air inlet; the high speed flowing air and the radiating fin are fully contact, so as to quickly volatilize the heat of the radiating fin; so as to greatly improve the cooling effect of the cooling box inside liquid it is good for the die casting machine hydrocooling the temperature of the temperature reducing component.
