摘要： Providing a method for reducing occurrences of a mold shift of a cope and a drag that have been molded by a flaskless molding machine and have been assembled by estimating a cause of a mold shift based on measurements and by taking appropriate measures, and a flaskless molding line that uses the method. The method for reducing occurrences of a mold shift of a cope and a drag (1, 2) that have been molded by a flaskless molding machine (200) and have been assembled comprises a step of measuring specific data at positions where a mold shift may occur during a process for manufacturing or taking out the cope and the drag, and a step of determining if the obtained specific data are within an allowable range.

摘要： When pressing kneaded sand in a kneading sand tank into a mold by a pressing member, a pressing force applied to a kneaded sand layer in the kneading sand tank is monitored and a moving position of the pressing member is monitored from when the pressing member starts to move. A pressing start time at which the kneaded sand starts to flow into the mold is identified based on the pressing force applied to the kneaded sand layer in the kneading sand tank, and a pressing starting position of the pressing member at the pressing start time is identified. As a result, the pressing start time and the pressing starting position of the pressing member when the kneaded sand starts to flow into the mold are accurately identified, so the reliability of a filling evaluation of the kneaded sand into the mold is improved.

摘要： A core forming device is equipped with a kneading tank in which raw materials of a core are kneaded, a raw material supply unit that supplies the raw materials to the kneading tank, a mold that accommodates a kneaded material including the raw materials kneaded in the kneading tank and that forms the core, a piston that injects the kneaded material into the mold, a position sensor that detects a position of the piston, and a control unit that controls a supply amount of the raw materials supplied to the kneading tank from the raw material supply unit. The control unit determines the supply amount of the raw materials based on a difference between the position of the piston upon completion of injection and a reference position of the piston.

摘要： A method of catching overflow of a liquid fluid utilized to cast a component is disclosed. Sand is compacted to form a mold. A cutter of a cutting device is in a disengaged position spaced from a top surface of the mold when the cutting device is in a first position and the cutter is in an engaged position engaging the top surface of the mold when the cutting device is in a second position. The cutter is actuated when the cutting device is in the second position and the cutter is in the engaged position to remove sand from the top surface to define a recess therein to catch overflow of the liquid fluid. The recess is spaced from an opening. At least one blocking mechanism, blowing mechanism and adjustment mechanism is utilized to assist the cutting device.

摘要： An overflow system for casting a component is disclosed. The system includes a mold formed of sand. The mold includes a top surface that defines an opening for receiving a liquid fluid. A trenching assembly includes a cutting device movable relative to a frame between a first position and a second position. The cutting device includes a cutter that is in a disengaged position spaced from the top surface when the cutting device is in the first position and in an engaged position engaging the top surface when the cutting device is in the second position. The cutter defines a recess in the top surface when the cutter is in the engaged position. The recess is spaced from the opening for receiving excess liquid fluid. The trenching assembly further includes at least one of a blocking mechanism, a blowing mechanism and an adjustment mechanism that assists the cutting device.

摘要： A flaskless molding method, wherein a match plate (5) is held between an upper flask (2) and a lower flask (3) and squeeze plates (6) and (7) are inserted into the openings of the upper flask (2) and the lower flask (3) to form an upper manufacturing space and a lower manufacturing space with initial volumes. A foundry sand is filled in the upper and lower manufacturing spaces with the initial volumes through the supply ports of the flask (2) and (3) (first filling). Next, the squeeze plates (6) and (7) are retreated to expand the upper and lower manufacturing spaces more than the initial volumes. The foundry sand is filled again in the expanded upper and lower manufacturing spaces through the supply ports (second filling). After the second filling is completed, the squeeze plates (6) and (7) are advanced to compress the foundry sand in the upper and lower manufacturing spaces so as to manufacture the upper and the lower flasks stacked on each other.

摘要： A space defined by inside surfaces of a main molding flask and lower auxiliary flask and the upper surface of a pattern plate where the upper surface of the pattern plate is retained at a predetermined level along the inside surfaces of the main molding flask and lower auxiliary flask is filled with an amount of molding sand. The molding sand is then squeezed in the space with upper and lower press heads in at least one of upward and downward directions to form at least one of first and second halves of a sand mold such that a lower surface of the first or second half of the sand mold is formed at a desired level along the inside surfaces of the main molding flask and lower auxiliary flask irrespective of edges of the main molding and lower auxiliary flasks. The desired level is determined by the level of the upper surface of the pattern plate at the time when the squeezing step has finished.
