Abstract
This invention relates to a cooling process suitable for foam molding of a synthetic resin and its cooling apparatus. Cooling water which is supplied into a flowing pressurized gas is turbulently jetted in the form of a mist into the overall area of respective chambers in a pair of molds. The mist, adhering uniformly to the overall walls of the molds remove latent heat from the mold surface, and consequently uniformly cool the entire mold. Further, a large quantity of steam generated from the mist as well as excess mist are forcibly discharged outside the chambers by a preferred suction means including a blower, etc., whereby the cooling effect on the walls of the molds is further enhanced.
