Abstract: A method for managing a casting process based on measured properties of molding sand is provided so that casting defects or energy used can be reduced by changing the molding conditions for the mold to be produced or changing the steps after molding. The method for managing a casting process based on the properties of the molding sand comprises a step (1) of measuring the properties of the molding sand just before the molding sand is supplied to a molding machine (40) and a step (2) of determining if the measured properties of the molding sand comply with predetermined properties, wherein, if by the step of determining it is found that the measured properties do not comply with the predetermined properties, a mold is molded to have less strength than that of a mold that is molded by using molding sand whose properties do comply with the predetermined properties.

Abstract: A return sand cooling system, including: a sand moisture and temperature measuring instrument measuring the moisture content and temperature of the return sand; a control device determines an appropriate water addition amount, which is an amount of water to be added to the return sand; a water-sprinkling cooling device adds water of the appropriate water addition amount to the return sand and cools the return sand by the latent heat of vaporization of water to obtain the cooled return sand; an air introducing device that introduces air into the water-sprinkling cooling device; and an introduced air temperature and humidity measuring instrument measures the temperature and humidity of introduced air to be introduced into the water-sprinkling cooling device; the control device determining the appropriate water addition amount on the basis of the moisture content and temperature of the return sand, and the temperature and humidity of the introduced air.

Abstract: To provide a device and a method for detecting, before pouring starts, any misalignment between a cope and a drag that have been molded by a flaskless molding machine and then assembled. The device (40) that can detect any misalignment between the cope (2) and the drag (3) that have been molded by the flaskless molding machine (1) and then assembled and that are being transported to the position for pouring comprises a plurality of means (51), (52), (53) for measuring distances to the cope and the drag that measures the distances (S11), (S12), (S13), (S21), (S22), (S23) to the cope and the drag, and a means (48) for calculating a degree of a misalignment between the cope and the drag on a basis of the distances to the cope and the drag that have been measured by the means for measuring distances to the cope and the drag.
