摘要： A method for introducing and compacting molding sand S in a mold space defined by a pattern plate (10a), a lower auxiliary frame (16b), a flask (18), a filling frame (20), and multi-segmented squeeze feet (36a). First, the molding sand S is introduced into the mold space. The squeeze feet (36a) are then lowered to apply a first squeeze to the mold sand S in the mold space under a condition wherein at least the lower frame (16a) cannot be lowered. The squeeze feet (36a) are then lowered to apply a second squeeze to the mold sand S in the mold space under a condition wherein the lower frame (16a), the flask (18), and the filling frame (20) can be lowered.

摘要： In a molding machine, foundry sand thrown into a molding space defined by a pattern plate and flask members is compressed in two steps. Namely, in the first step a lower subsidiary flask is stationary while in the second step the flask is movable. The pattern carrier molding machine comprises a molding base, flask-setting cylinders, a lift-support frame, and a segment-squeeze sand hopper. The auxiliary flask 62 of the compact pattern-plate carrier is installed movably up and down through a plurality of upward oil cylinders 63,63 that are expanded/contracted via special oil cylinders 64,65 operated by outside cylinders 68,69.

摘要： A sand hopper (28) is provided at its lower position (40) with a plurality of nozzles (42) and a plurality of squeeze feet (46), the pressure of which is controlled, and which are located adjacent to a side of each squeeze foot. The sand hopper (28) is supported by supporting means (22, 26) such that it can move vertically. A mold space is defined by a pattern plate having a pattern (74a), a flask (4), a filling frame (52), and a sand hopper (28) having a plurality of squeeze feet (46) disposed above the filling frame (52). By discharging molding sand from the nozzles (42), it is introduced into the mold space. The mold sand (S2) in the mold space is compacted by the squeeze feet by lowering the sand hopper toward the mold space. Since the molding machine is so arranged, both introducing molding sand into a mold space and compacting the introduced molding sand are performed at one station (a molding-sand introducing and compacting station).

摘要： A method and system using a molding apparatus with frames by which the amount of molding sand that overflows the molding apparatus and that must be taken out of a mold that is prepared by a molding operation is minimized, and by which the density of the mold within a frame is substantially uniform. The molding sand filling cavity is defined by a pattern plate, a molding frame that can be put on the pattern plate, a filling frame that can be put on the molding frame, and a covering apparatus having a plurality of squeezing feet. The squeezing feet can enter the filling frame and can be temporarily held at certain positions where certain distances are kept between the lower ends of the squeezing feet and surfaces of the patterns on the pattern plate that are opposed to the lower ends. Molding sand is supplied to the molding sand filling cavity. Then, the molding sand is compressed by the squeezing feet.
