FIELD: cooling.
SUBSTANCE: group of inventions relates to cooling system (10) for moulding fixtures, and particularly for foundry moulds, and a device for mixing air and treated water. Cooling system (10) for moulding fixtures comprises: water treatment means (11); compressed air generation means (12); means (13) for pressurising the treated water; device (14) for mixing air with the treated water, and for controlled ejection of atomised water under pressure toward cooling circuit (16) of a moulding fixture. Device for mixing air and treated water also comprises a water pipe with a calibrated nozzle, air line and a tee connector for pressurised water inlet and compressed air.
EFFECT: technical result achieved with the use of the group of inventions is ensuring that the formation of cracks in the mould is avoided with a thermal head between water and its internal temperature.
