Abstract
A multi-path internal microporous efficient refrigeration method and device for a frozen sand mold is provided. The device includes a frozen sand molding chamber, an electric lifting platform, a teflon porous lining, a removable porous aluminum plate, a frozen sand mold refrigeration device box, a sealing cover plate, an ultrasonic piezoelectric sheet, a U-shaped condenser tube, an ultrasonic generator, and a low-temperature refrigeration system. The teflon lining and the removable porous aluminum plate are provided with through hole structures of the same size and shape for rapid cooling from the surface to core of molding sand. The lifting platform is opened and the bumpy-ridge teflon lining rises to a highest point to facilitate demolding. The high- and low-frequency dual mode of the ultrasonic piezoelectric sheet can be used for vibrating and compacting the frozen sand mold, and can also assist in cutting forming.
