Abstract

PURPOSE: To clamp molds with even tightening force at the upper and lower mating faces and make fastening easy by combining the molds respectively provided with the fastening means secured with a plurality of nuts and a plurality of holes, passing bolts in the holes of the latter and fastening the molds.
CONSTITUTION: A pattern 4 and a flask 5 are placed on a molding board and the fastening means 6 secured and integrated through welding or the like with a plurality of nuts 6a by means of connecting members 6b are disposed between both. Next, casting sand 7 is compacted so that it becomes flush with the contact with a lower mold 2 at the surfaces of the pattern 4 and fastening means 6. At this time, covering is beforehand so provided that the casting sand 7 does not enter the internal screws of the fastening means 6. After the molding, the pattern 4 and flask 5 are removed, whereby an upper mold is made. The lower mold 2 is made in the manner similar to the above by placing the pattern 4a and flask 5 on the molding board 3, disposing a wooden pattern 8 and compacting the casting sand 7. Next, the upper mold 1 and lower mold 2 are combined and the bolts 8 are passed through the holes 8a and are screwed into the fastening means 6, whereby the molds are fastened.
