    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 casting mold molding device, a casting mold quality evaluation device, and a casting mold quality evaluation method are capable of evaluating the quality (casting mold strength) of a molded green sand mold without measuring a green sand mold by using a casting mold strength gauge each time a green sand mold is molded in one frame. A green sand mold molding sensor that, during molding of a green sand mold, measures a pressure value applied to a joining section between green sand introduced into a casting mold molding space and a plate having a model attached thereto; and a casting mold quality evaluation device that evaluates the quality of a molded green sand mold from the pressure value.
