摘要： The disclosed invention provides a molding machine that defines upper and lower molding spaces while cope and drag flasks 12,13 and a match plate 11 clamped therebetween are rotated from a horizontal position to a vertical position, and that readily places a core into a lower mold within the drag flask. An upper squeeze member 14 is insertable into the cope flask 12 with its pressure-applying plane being opposed to the upper face of the match plate 11. The pressure-applying plane defines an upper molding space together with the upper face of the match plate 11 and the cope flask 12. A pivoting frame 23 supports the cope and drag flasks 12,13, a match plate 11 clamped therebetween, and the upper squeeze member 14, such that they rotate in unison between a horizontal position, in which the pressure-applying plane of the upper squeeze member 14 is oriented vertically downward, to a vertical position in which the pressure-applying plane is oriented horizontally. A fixed, vertical, filling frame abuts the drag flask 13 when the flasks 12, 13 and the match plate 11 that is clamped therebetween are in the vertical position. A lower squeeze member 16 has a pressure-applying plane that is oriented horizontally, and is insertable into the filling frame and the abutting drag flask 13. The pressure-applying plane of the lower squeeze member 16 defines a lower molding space together with the lower face of the match plate 11, the drag flask 13, and the filling frame 15. To place a core into a lower mold within the drag flask, the drag flask 13 is laterally moved from a position that is immediately beneath the cope flask 12 such that an open working space is provided.

摘要： Disclosed is a molding method for separating a cope flask and a drag flask from a match plate at the same time. The method comprises the steps of: holding the match plate between the cope and drag flasks; inserting an upper squeeze member and a lower squeeze member into openings of the cope and drag flasks, which are opposed to the match plate, to define an upper molding space and a lower molding space, respectively; filling the defined molding space with molding sand; and driving the upper and lower squeeze members toward the match plate to squeeze the molding sand within the upper and lower molding space to mold an upper mold and a lower mold at the same time. The cope and drag flasks that are included within said molded upper and lower molds are forcibly pushed away from the match plate at the same time when the flasks are stationary.

摘要： A sand-introducing device that uses air for introducing molding sand in a molding space or spaces is provided. The device is provided with air-permeable partitioning plates that define a double-walled structure together with the wall of the body of the device. The air-permeable partitioning plates are easily produced, they can easily inject pressurized air of a desired pressure, and they will not need regular maintenance. The body of the device, which acts as a pressure tank, defines a double-walled structure together with the air-permeable partitioning plates (10, 11), thereby defining chambers (12, 13). In the sand-introducing device that uses air, while molding sand is fluidized by pressurized air injected from the air-permeable partitioning plates, it is introduced in a molding space. Each air-permeable partitioning plate is made of a porous resin or metal.
