摘要： A method for compacting molding sand in a mold space defined by a pattern plate, which is fixed in a horizontal position when the molding sand is compacted, a leveling frame disposed for vertical sliding movement around the outer periphery of the pattern plate, a frame member disposed for vertical movement above the leveling frame, and a filling frame disposed for vertical movement above the frame member. The method comprises the steps of feeding molding sand into the mold space, primarily compacting the molding sand in the mold space from above by compacting means while at least the leveling frame is being set so that it cannot be lowered, and secondarily compacting the molding sand in the mold space from above by the compacting means while the leveling frame the frame member, and the filling frame are set so that these elements can be lowered.

摘要： The purpose of the present invention is to provide an apparatus for molding a mold and a method for molding a mold which can prevent foundry sand from becoming attached to an inner surface of a sand hopper and to make the structure of the apparatus simple. The apparatus supplies foundry sand into a molding space formed by a pattern plate, a flask, and a filling frame that are placed on a pattern carrier by means of a sand-filling device. Then the apparatus squeezes the foundry sand in the molding space by means of a squeezing device to mold a mold. The apparatus comprises a sand hopper that stores foundry sand in its inside. The sand hopper is disposed above the flask and the filling frame. The apparatus further comprises an openable louver gate disposed in the sand hopper. The apparatus further comprises an opening and closing device for opening and closing a sand-feeding opening. The sand-feeding opening is an opening for supplying the foundry sand into the sand hopper. The opening and closing device is disposed above the sand hopper. The apparatus further comprises an air-blowing chamber attached to the inner surface of the sand hopper.

摘要： The disclosed molding machine defines upper and lower mold cavities while cope and drag flasks 12,13, having a match plate 11 sandwiched therebetween, are rotated from their horizontal positions to their vertical positions. 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 mold cavity 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, having a match plate 11 sandwiched 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 cope and drag flasks 12,13, having the match plate 11 sandwiched 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 abutted drag flask 13. The pressure-applying plane of the lower squeeze member 16 defines a lower mold cavity together with the lower face of the match plate 11, the drag flask 13, and the filling frame 15.

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.
