(Operation) Next, the operation of the apparatus configured as described above will be described. The cylinders (2) and (2) are extended to the required length to raise the table (3), and the casting frame (31) is placed on the model plate (5) and pushed up from the roller conveyor (9) with a collar. Place the filling frame (30) on the casting frame (31). Next, the contraction operation of the cylinder (29) moves the louver hopper device (11) and the compressed air blowing device (12) to the right to move the louver hopper device (11) to a position directly above the fill frame (30). Then, the cylinder (28) is expanded / contracted to feed the molding sand in the louver hopper device (11) into the casting frame (31) and the filling frame (30). After the completion of the injection of the molding sand, the louver hopper device (11) and the compressed air blowing device (12) are moved to the left by the extension operation of the cylinder (29) to set the compressed air blowing device (12) to the fill frame (30). To a position immediately above the cylinder (21) (21), and then the cylinders (2) and (2) are further extended under the extension operation of the cylinders (21) and (21) to open the compressed air blowing device (12). 30) Place it on top and push it up to make contact with the ceiling frame (23). Next, the cylinder (27) is contracted to open the compressed air outlet (25), the compressed air in the cover member (24) is supplied into the compressed air storage tank (15), and then the valve mechanism (20). ) Is operated to open the exhaust hole (19) to discharge the compressed air in the upper chamber of the cylinder (18) body of the cylinder mechanism (17). Then, the piston of the cylinder mechanism (17) moves the compressed air storage tank (1
5) It is pushed up by the compressed air in the outlet (14)
(14) is opened, and the compressed air in the compressed air storage tank (15) is blown into the cover member (22) all at once. The compressed air blown in compresses the molding sand in the filling frame (30) and the molding frame (31) and, at the same time, flows through the molding sand and is discharged from the vent hole (4) of the model plate (5). The foundry sand is precompressed. Then the cylinder (27)
The compressed air outlet (25) is closed by the valve (26) by the expansion operation of (1), and then the on-off valve (not shown) is opened and closed to discharge the compressed air in the compressed air storage tank (15). Next, after making the cylinders (21) and (21) freely contractible, the cylinders (2) and (2) are further extended to raise the model plate (3), the flask (31), etc. As a result, the molding sand in the filling frame (30) and the casting frame (5) is squeezed by the model plate (5) and the squeeze board (13) to form a green mold. After the squeeze is completed, the model plates (3) and the like are lowered by the contraction operation of the cylinders (2) and (2), and the flask (31) is placed on the flanged roller conveyor (9) to perform die cutting.
After the contraction operation of the cylinders (2) and (2) is completed, the molding flask (31) with a built-in green mold is carried out from above the model plate (5) and the empty molding frame (31) is directly above the model plate (5). The louver hopper device (11) is supplied with a required amount of molding sand, and one cycle is completed.
