Abstract: A device for spraying a mold-releasing agent and a method therefor is provided by which a sticker and a defective drawing of a mold are prevented from occurring by detecting a leak of the mold-releasing agent, a clogging of a nozzle for spraying the mold-releasing agent, or a failure of a piece of equipment of the device for spraying the mold-releasing agent, to properly control the volume of the sprayed mold-releasing agent. A device 1 for spraying a mold-releasing agent that sprays a mold-releasing agent A on a pattern plate 20 in a molding machine that forms molds from molding sand S by using a flask 10 and the pattern plate 20, comprising a nozzle 30 for spraying the mold-releasing agent that sprays the mold-releasing agent A on the pattern plate 20, a piping 40 for supplying the mold-releasing agent that supplies the mold-releasing agent A to the nozzle 30 for spraying the mold-releasing agent, a flow sensor 42 that measures a flow rate of the mold-releasing agent A that flows in the piping 40 for supplying the mold-releasing agent, and a controller 90 that detects a leak of the mold-releasing agent A, a clogging of the nozzle 30 for spraying the mold-releasing agent, or a failure of a piece of equipment of the device 1 for spraying the mold-releasing agent, based on the measured flow rate.

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.
