Claims

[Scope of utility model registration request]

In a formwork core device for manufacturing U-shaped gutter blocks, a pair of columns are installed upright at a predetermined interval in the width direction of the gutter block, and the gutter is attached to one column so that its upper part is inclined inward. One inner wall of the block and a part of the tilting core for bottom molding adjacent thereto, and the other inner wall of the gutter block fixed to the other column and a part of the fixed core for bottom molding adjacent thereto. and a gutter block disposed between the tilting core and the fixed core, and having one end side in the width direction tiltably pivoted inside the upper end of the tilting core, and molding the other bottom surface of the side gutter block. a tilting top plate, an operating member that can be operated from the outside, and a tilting core connected to the tilting top plate and the operating member so as to operate the tilting core inwardly and the operating member in conjunction with the operation of the operating member. A core device comprising a connecting operation mechanism that operates to draw the tiltable top plates downward.
