Abstract:
To provide a production apparatus for producing laminated blocks provided with a structure in which burrs or the like generated by a suspending board do not interfere upon lamination.SOLUTION: A production apparatus for producing laminated blocks comprises: a body flask 100 molding a front wall, a rear wall and side walls of each laminated block; an upper press part for compacting laminated blocks from above; and a hollow flask 300 molding a hollow part surrounded by the front wall, the rear wall and the side walls of each block. The hollow flask 300 is suspended and fixed by a suspending board 400 fitted to an upper end side of the body flask 100. The upper press part comprises an insertion part inserting the suspending board 400 when, for compacting and molding each laminated block, it drops toward the main flask 100 and presses the same. In the upper press part, a part adjacent to the insertion part is provided with a projection part projecting downward, and a recessed part capable of storing burrs generated around the insertion part is formed at each laminated block by the projection part.SELECTED DRAWING: Figure 1
