Next, the operation of the apparatus thus configured will be described.
First, the table (5) is moved by the extension operation of the cylinder (2).
Then, the model plate (7) is lifted to place the casting frame (11) on the model plate (7) and the fill frame (12) on the casting frame (11) one after another in a superposed state. The extension operation of the cylinder (2) is once stopped to stop the rising of the table (5) and the like. Then
The cover member (15) is moved outward from the position directly above the fill frame (12), and a sand pan hopper (not shown) is attached to the fill frame (1).
It is carried into the position just above 2), and subsequently, the molding sand (11) and the filling frame (12) are charged and filled by the sand container hopper. Next, the sand hopper is moved to the outside and the cover member (15) is moved to a position directly above the fill frame (11) again, and then the cylinder (2) is further extended to move the table (5) and the like. The cover member (15) is raised and the cover member (15) is placed on the fill frame (12), and the cover member (15) is brought into contact with the backing plate (30), and at the same time, the air supply pipes (18) (18)
The upper end of the surge tank (22) through the seal member (32)
Abut the bottom surface of the air supply pipe (18) (18) to the exhaust hole (23)
Connect airtightly to (23). Then the cylinder (2
When the exhaust hole (23) (23) is opened by extending 9), the compressed air in the surge tank (22) is discharged from the exhaust hole (23) (23), and the air supply pipes (18) (18) and Air supply hole (19) (1
9) and then flows into the cover member (15). The compressed air that has flowed into the cover member (15) flows through the molding sand of the fill frame (12) and the casting frame (11), and the vent hole (6).
(6) The gas is discharged from the exhaust hole (4) through the recess (3). In this case, when the compressed air flows through the molding sand, the particles of the molding sand are made to flow toward the vent holes ((6) and (6) and are densely and firmly deposited on the surface of the model plate (7). Thus, a layer of the foundry sand is formed along the surface of the model plate (7), and after supplying compressed air to the cover member (15) for a predetermined time,
The cylinder (29) is contracted to close the exhaust holes (23) (23) and stop the supply of compressed air to the cover member (15).
Then, the cylinders (16) (16) are extended to operate the segment squeeze hoods (17) (17) to squeeze and solidify the foundry sand in the filling frame (12) and the casting frame (11). After the squeeze is completed, the cylinders (16) (16) are contracted to raise the segment squeeze hoods (17) (17), and then the cylinder (2) is contracted to lower the table (5). Then, first, the cover member (15)
Mounted on the roller with ribs of the roller conveyor with collar (9), then the fill frame (12) on the support means (13) (13), and finally the casting frame (11) with the roller conveyor with collar ( The mold in the flask (11) is separated from the model plate (7) while being placed on the roller with a collar of (10). After that, the flask (11) containing the mold is taken out and another empty flask (11)
Is carried to a position just above the model plate (7) through the roller conveyor (10) with a collar, and one cycle is completed.

なお、盛枠(12)は省略してもよい。The fill frame (12) may be omitted.

(Effect) As is apparent from the above description, according to the present invention, the cover member (15) in which the air supply pipes (18) (18) are erected at the position just above the table (5) for moving the model plate (7) up and down. ) Is arranged so that it can be moved in and out and can be moved up and down, and the air supply pipes (18) and (18) are provided at a position just above the table (5) above the cover member (15).
A surge tank (22) having exhaust holes (23) (23) capable of communicating with the exhaust gas is fixedly arranged, and the exhaust holes (23) (23) are connected to the valve (25).
Since it is opened / closed by (25), the cover member and the surge tank are linearly communicated with each other and the distance between them is very short as compared with the conventional device of this type, and therefore compressed air is An excellent effect is obtained in that the pressure loss generated from the surge tank (22) until reaching the cover member (15) is extremely small.
