Abstract:
1. A flaskless molding machine comprising: two molding flasks that have a matching plate sandwiched between them, the two molding flasks being positioned in a way that one of the opening ends of the molding flasks is opposed to each other and each of the other opening ends of the molding flasks is engaged with a squeezing board, whereby a pair of spaces is formed, each space being a space to produce a mold (molding space), into which spaces molding sand is filled by air through each of openings for introducing the molding sand, disposed on a wall of each of the two molding flasks that are opposed to each other, as described above, the flaskless molding machine thus constituted molding two molds by squeezing the molding sand with the squeezing boards, wherein the molding flasks comprise an upper molding flask and a lower molding flask, and further comprising either a lower filling frame or an upper filling frame, and wherein if the molding flasks comprise the lower filling frame the openings for introducing the molding sand are disposed on side walls of the upper molding flask and the lower filling frame; wherein if the molding flasks comprise the upper filling frame, the openings for introducing the molding sand are disposed on the side walls of the upper filling frame and the lower molding flask; and wherein the lower filling frame or the upper filling frame has a member for introducing the molding sand, the member having an opening for introducing the molding sand and being changeable wherein a position of the opening for introducing the molding sand of the member for introducing the molding sand relative to a parting plane can be changed, depending on a direction in which the member for introducing the molding sand is fixed.
