Abstract: A method for detecting powder is performed in a powder detection device including a pair of electrodes arranged to be opposed to each other with a gap interposed therebetween and an electric circuit electrically connected to the pair of electrodes. The method includes detecting powder filling in a case where the electric circuit together with powder and the electrodes forms a closed circuit when the powder fills the gap.

Abstract: A method is provided for measuring a shift between a carrier for a pattern (a carrier plate) and a flask and preventing a defect caused by a shift in the cavity parts. The method for preventing a defect caused by the shift in the cavity parts in molding a cope and a drag with flasks by using a cope flask (110) that is assembled with a carrier plate (130) for the cope flask and a drag flask (120) that is assembled with a carrier plate (140) for the drag flask, comprises the steps of measuring a shift between the carrier plate (130) for the cope flask and the cope flask (110), measuring a shift between the carrier plate (140) for the drag flask and the drag flask (120), measuring a shift between the cope flask (110) and the drag flask (120) that have been assembled, determining if a shift in cavity parts is within an allowable range, wherein the data on the shift is obtained based on the shift between the carrier plate (130) for the cope flask and the cope flask (110), the shift between the carrier plate (140) for the drag flask and the drag flask (120), and the shift between the cope flask (110) and the drag flask (120, that have been assembled.

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: A mold molding apparatus can successively mold casting molds having the necessary casting mold strength, and a method for controlling the mold molding apparatus. A molding sensor measures a pressure of molding sand exerted on a surface of one or both of a pattern plate and a squeeze foot, or on a surface of one or both of a pattern plate and a squeeze board; and a control device that controls operation of the mold molding apparatus based on outputs from the molding sensors.

Abstract: A flaskless molding machine includes an upper flask, a lower flask capable of clamping a match plate with the upper flask, a filling frame connectable to the lower flask, a first squeeze board movable into and out from the upper flask, a second squeeze board movable into and out from the filling frame, a filling frame cylinder moving the filling frame relative to the second squeeze board, a squeeze cylinder integrally moving the filling frame, the second squeeze board, and the filling frame cylinder, and a control unit configured to control the filling frame cylinder and the squeeze cylinder. A mold height changing unit includes a stopper limiting a stroke length of the filling frame cylinder to a predetermined length.
