The gas diffuses into the sealed chamber through the gap 23 between the station plate 4 and the formwork 20 created by the protruding member 22 provided at the bottom of the gas discharge pipe 7, and is discharged to a gas processing device such as an adsorption device (not shown). It is processed, rendered harmless and dissipated.
このようにしてガスにより鋳物砂が硬化して鋳型が製造
されると、ガスの供給が中止され、次いでガス吹込管９
より空気が送り込まれて、密閉室内に残存するガスを排
出する。When the molding sand is hardened by the gas and the mold is manufactured in this way, the gas supply is stopped, and then the gas blowing pipe 9
More air is pumped in to exhaust any gas remaining in the sealed chamber.

れない。In the apparatus of the present invention, the gas plate is vertically movably provided between the station plate and the top plate of the bottomless box, and the sealing mechanism for tightly fitting the gas blowing hole of the gas plate to the lower end of the gas blowing pipe includes: As shown in the figure, it is desirable to provide the auxiliary plate 10 to which the gas plate 16 is detachably attached, but the present invention is not limited thereto.
例えばガスプレート１６を直接箱６の上板より吊り下げ
、ガスプレートのガス吹込孔１８に対し上面にシール材
を設げて直接ガス吹込管９の下端９′に密合させるよう
にしてもよい。For example, the gas plate 16 may be suspended directly from the upper plate of the box 6, and a sealing material may be provided on the upper surface of the gas blowing hole 18 of the gas plate so that the gas plate 16 is directly fitted to the lower end 9' of the gas blowing pipe 9. .
しかし図面に示したように補助板を設ければ、多種少量
の鋳型の製造の場合に各種寸法のガスプレートを迅速容
易に交換できるため特に好ましいものである。However, it is particularly preferable to provide an auxiliary plate as shown in the drawings, since gas plates of various sizes can be quickly and easily replaced when molds of various types and small quantities are manufactured.

外部に発散させることな〈実施することができる。Since the apparatus of the present invention has the above-described structure, it does not emit harmful gases to the outside when manufacturing molds by hardening molding sand using gases such as carbon dioxide gas and triethylamine. It can be implemented.
また同一の鋳型を量産する場合に、作業者は型込めした
型枠を型枠ステーションプレート上に載置するだけでよ
く、従来機の場合のように型枠の上にさらにガスプレー
トを載置したり、作業が終れば取除くという手間が不要
で作業が能率化される。In addition, when mass producing the same mold, the operator only needs to place the filled mold on the mold station plate, and then place the gas plate on top of the mold as in the case of conventional machines. The work becomes more efficient as there is no need to remove it when the work is completed.
また、ガスプレートを型枠上に載置するのを忘れて機械
を操作して、不良品を作るという恐れが全（ない。In addition, there is no fear of forgetting to place the gas plate on the formwork and operating the machine, resulting in defective products being produced.
また型枠の寸法が変る場合も前記のようにガスプレート
の交換を迅速容易に行なうことができる。Furthermore, even when the dimensions of the formwork change, the gas plate can be quickly and easily replaced as described above.
また本発明の装置によれば、作業者は第１図のように箱
６の下方に吊り下げられたガスプレート１６を見ること
ができるので、その真下に型込めした型枠２０を置くこ
とにより、第６図のように型枠２０とガスプレート１６
は正確に接合される。Furthermore, according to the device of the present invention, the operator can see the gas plate 16 suspended below the box 6 as shown in FIG. , the formwork 20 and the gas plate 16 as shown in FIG.
are accurately joined.
ガス吹込管９とガスプレートのガス吹込孔１８は当然正
確に位置が合い、常に正しい作業が行なわれる。Naturally, the gas blowing pipe 9 and the gas blowing hole 18 of the gas plate are precisely aligned, so that correct work is always performed.
しかし、従来機においてガスプレートが本発明のように
吊り下げてなく、分離され独立しているガスプレートを
作業者が型枠の上に置いた後に、型枠をステーションプ
レート上に置く場合には、正しい位置を見出すのが困難
であり、ガス吹込管の下端とガスプレートのガス吹込孔
とが一致せず、ガスがうまく型枠内に吹込まれない恐れ
が生ずるが、本発明においてはこのような失敗は全く生
じない。However, in the conventional machine, the gas plate is not suspended like in the present invention, and when the operator places the separated and independent gas plate on the formwork and then places the formwork on the station plate. However, in the present invention, it is difficult to find the correct position, and the lower end of the gas blowing pipe and the gas blowing hole of the gas plate do not match, resulting in the possibility that the gas will not be properly blown into the formwork. No failures occur at all.
これを要するに本発明の装置は、操作性が良く高能率の
作業ができるなど、従来のものに比較して優れた機能を
有するものである。In short, the device of the present invention has superior functions compared to conventional devices, such as good operability and high efficiency.
