ABSTRACT:
Sand is charged into two spaces defined by a match plate, a pair of flasks, and a pair of squeeze plates, and is then compressed by moving the squeeze plates in the flasks toward the match plate to form the cope and drag molds. The properties of the molding sand are detected during the forming of the molds in order to suitably adjust the sand and the device. The device includes linear encoders connected to the squeeze plates so as to detect the amounts of the movements of the squeeze plates, and an electrode penetrating one squeeze plate so as to detect the electric resistance or the water-content value of the mold in the flask.
