摘要： In a conventional apparatus for molding molds, foundry sand is filled in an upper and a lower molding space defined by a match plate, an upper and a lower flask, and an upper and a lower squeeze plate, and then the foundry sand is squeezed by causing the upper and the lower squeeze plate to further approach each other. However, the hardness and strength near the inner surface that corresponds to the match plate, of an upper and a lower mold made by the conventional apparatus, are not high enough. To solve this problem, in this invention the following method is applied: a method for squeezing foundry sand filled in an upper and a lower molding space, comprising: a step to squeeze the foundry sand by causing the upper and the lower squeeze plate to further approach each other, and a step to squeeze it by causing the pattern portions of the match plate to move to each of the upper and the lower squeeze plate.

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.
