から分離させて所望の鋳型を得る。(Operation of the device) Next, the operation of the device configured as described above will be explained. The model board 1 is lifted by lifting the lifting table 2.
Then, the flask 5 is raised, the squeeze plate 10 is fitted into the flask 5, and the flask 5 is brought into contact with the fixed frame 6, and a hollow chamber C is defined by the model plate 1, the flask 5, and the squeeze plate 10. to be accomplished. Next, the same amount of kneaded sand S added with a binder and a hardening agent for self-hardening mold making as the volume of the hollow chamber C is put into the hopper 7, and then the hollow chambers 3, C, and 12 are sucked. When the slide gate 8 is opened after the pressure is reduced, the kneaded sand S in the hopper 7 is sucked into the hollow chamber C and filled therein. In this case, since the inside of the hollow chamber C is subjected to suction and pressure reduction from the upper and lower bend holes 13 and 4, the kneaded sand S in the hopper 7 is uniformly sucked and filled throughout the inside of the hollow chamber C. After filling the sand, the suction action to the hollow chambers 3, C, 12 is stopped, and then the cylinders 9, 9 are extended and the squeeze plate 1 is removed.
0 is lowered, and the kneaded sand S in the hollow chamber C is squeezed by the squeeze plate 10. After the squeeze is completed, the cylinders 9, 9 are contracted to raise the squeeze plate 10, and the model plate 1, flask 5, etc. are lowered together with the elevating table 2. After maintaining the matching state of the mold plate 1 and the mold flask 5 until the filling sand in the flask 5 is hardened, the mold plate 5 containing the hardened sand is replaced with the mold plate 1.
to obtain the desired mold.

るなどの優れた実用的効果を奏する。(Effects of the invention) As is clear from the above explanation, the present invention has a squeeze plate having a hollow chamber directly below the hopper that is connected to the vacuum pump so that it can be raised and lowered.
By reducing the pressure in the hollow chamber defined by the model plate, casting flask, and squeeze plate in cooperation with the suction action of the model plate, the kneaded sand in the hopper can be uniformly sucked and filled into the hollow chamber. In addition, the squeezing action of the squeeze plate increases the filling density of the sand in the hollow chamber, making it possible to accurately form a desired mold without requiring a large clamping device or a blow head with multiple structures. It has excellent practical effects such as:
