介して吸引しながら、通ガスする装置であるが、中子型
6の大小、形状によってその都度、ガス吹込ボックスを
取替えなければならない。FIG. 1 shows an apparatus in which a core mold 6 is placed in a container 1, a gas blowing box 4 is crimped onto the core mold 6, and gas is passed through while suctioning through a suction box 7. The gas blowing box must be replaced each time depending on the size and shape of the core mold 6.
またガスの漏洩を防止するために、すべての中子型6の
分割面に、シールを施さなければならないので、中子型
6の製作費が高くなる。Furthermore, in order to prevent gas leakage, all the split surfaces of the core mold 6 must be sealed, which increases the manufacturing cost of the core mold 6.

0からガスを吹込む装置である。Figures 2 and 3 show equipment for passing gas in a vacuum atmosphere.
FIG. 2 shows a vacuum container in which the container 1 is raised and lowered by an air cylinder 8 and is crimped onto a suction box 7 to seal it, and FIG. 3 shows a horizontal vacuum container with a door 9 on one side. All core type 6
The container 1 is placed in a vacuum state by suction with a vacuum pump, the opening/closing valve 21 is closed, and the gas inlet 1 is closed.
This is a device that blows gas from zero.
しかしこれらの装置の欠点はいずれも、一旦真空状悪に
した容器l内に、ガスを吹込むことにより、真空度は著
しく後退し、ガスの拡散速度が緩慢になって、中子の硬
化に時間を要し、能率的でない。However, the disadvantage of all of these devices is that by blowing gas into a container that has been previously evacuated, the degree of vacuum deteriorates significantly, slowing down the rate of gas diffusion, and slowing down the hardening of the core. Time consuming and inefficient.
また中子型6と、容器1の間に生ずる空間に存在するガ
スは、中子の硬化にまったく寄与しないまま排出される
ので、ガスを無駄に消費する。Furthermore, the gas existing in the space between the core mold 6 and the container 1 is exhausted without contributing to the hardening of the core, so the gas is wasted.

ータンクに通ずる。The structure of the present invention will be explained below with reference to FIGS. 5 and 6'. A pressure-bonding cylinder 3 is attached to the top plate of a container 1 equipped with a guide tube 2, and a gas cylinder having a large number of small holes 11 in the bottom plate is attached. The blowing box 4 is fixed to the tip of the crimp cylinder 3 so as to slide on the guide tube 2. The gas blowing box 4 is
It is connected to a pipe 13 through a flexible tube 12 such as a rubber hose, and the pipe 13 branches into on-off valves 14.1, respectively.
5 and a pressure reducing valve, it leads to a gas tank and a purge air tank.

図の様な密室を形成する。In addition, both ends of a tube 5, which has approximately the same diameter as the container 1 and has a length approximately 25 times the radius, are tightly fixed to the opening imaging portion of the container 1 and the opening imaging portion of the guide tube 2, and are tightly fixed to the inner wall of the container 1. During the 6th
Form a closed room as shown in the figure.
なおチューブ5は、柔軟性にとみ、かつ非通気性、非伸
縮性の素材で成る。The tube 5 is made of a material that is flexible, non-breathable, and non-stretchable.
密室の上部はパイプ16につながり、パイプ16は分岐
してそれぞれ、開閉弁17.18を径てゴムホース等の
可撓管を介し吸引装置、およびエヤーコンプレッサーに
通fる。The upper part of the closed chamber is connected to a pipe 16, which branches and passes through on-off valves 17 and 18, respectively, to a suction device and an air compressor via a flexible tube such as a rubber hose.
上面に多数の小孔19を持つ吸引ボックス7は、開閉弁
21を径て鋼管を介し、吸引装置に接続される。また容
器1は、エヤーシリンダー8によって昇降し、外周つば
部には吸引ボックス7とロックされる、ロック装置20
を備えている。The suction box 7, which has a large number of small holes 19 on its upper surface, is connected to a suction device through an on-off valve 21 and a steel pipe. Further, the container 1 is raised and lowered by an air cylinder 8, and a locking device 20 is installed on the outer rim of the container 1, which is locked with the suction box 7.
It is equipped with
以上の構成で成る、この装置の作用を説明すれば、まず
開閉弁14.15.17.18.21を閉じた状態で、
エヤーコンプレッサーおよび、吸引装置を起動し、開閉
弁17を開けば、容器1の密室内の空気は吸引排気され
、チューブ5は、第5図の様に、容器1の内壁に吸着す
る。To explain the operation of this device with the above configuration, first, with the on-off valves 14, 15, 17, 18, and 21 closed,
When the air compressor and the suction device are activated and the on-off valve 17 is opened, the air in the closed chamber of the container 1 is suctioned and exhausted, and the tube 5 is adsorbed to the inner wall of the container 1 as shown in FIG.
つぎにエヤーシリンダー8によって容器1を引上げ、中
子型6を吸引ボックスに載置し、エヤーシリンダー8に
よって、容器1を下降してロック装置20でロックする
。Next, the container 1 is pulled up by the air cylinder 8, the core mold 6 is placed on the suction box, and the container 1 is lowered by the air cylinder 8 and locked by the locking device 20.
つぎに圧着シリンダー3により、ガス吹込ボックス4を
中子型6に圧着したうえ、開閉弁17を閉じ、開閉弁1
8.21を開けば、圧縮空気によりチューブ5が膨張し
て、中子型6の外壁に圧着されて、周辺の空間を塞ぐ。Next, the gas blowing box 4 is crimped onto the core mold 6 using the crimping cylinder 3, and the on-off valve 17 is closed.
When 8.21 is opened, the tube 5 is expanded by compressed air and is pressed against the outer wall of the core mold 6, closing the surrounding space.
この場合の空気圧は、チューブ5によってガス吹込ボッ
クス4が押戻されない様に予め、減圧して置く。In this case, the air pressure is reduced in advance so that the gas blowing box 4 is not pushed back by the tube 5.
つぎに開閉弁14を開き所定の時間、ガスを吹込んだ後
これを閉じ、開閉弁15を開いてパージ用エヤーを導入
する。これによってガスは中子型6の中を、強制的に通
過し、中子型6に充填された中子砂の溶剤と接触反応し
て、吸引ボックス7を介して排気される。所定の時間排
気したら、開閉弁15を閉じ、開閉弁17を開きチュー
ブ5を容器1の内壁に吸着させる。Next, the on-off valve 14 is opened and gas is blown in for a predetermined period of time and then closed, and the on-off valve 15 is opened to introduce purge air. As a result, the gas is forcibly passed through the core mold 6, reacts with the solvent of the core sand filled in the core mold 6, and is exhausted through the suction box 7. After evacuation for a predetermined time, the on-off valve 15 is closed, and the on-off valve 17 is opened to allow the tube 5 to be adsorbed to the inner wall of the container 1.
つぎに圧着シリンダー3によって、ガス吹込ボックス4
を引上げたうえ、ロック装置20を解除し、エヤーシリ
ンダー8によって、容器1を引上げて、中子型6を取出
す。Next, the gas blowing box 4 is pressed by the crimp cylinder 3.
Then, the locking device 20 is released, the container 1 is pulled up using the air cylinder 8, and the core mold 6 is taken out.
これら一連の操作は、電気的に遠隔操作され、単独また
は連動で、自動操作される。A series of these operations are electrically remotely controlled and automatically operated independently or in conjunction with each other.
以上の様に、この装置によれば、つぎの様な利点がある
。As described above, this device has the following advantages.
イ、中子の大小、形状に関係なく無駄な空間がなくなる
ので、ガスの消費が少ない。B. Gas consumption is reduced because there is no wasted space regardless of the size or shape of the core.
口1強制通ガスのため、中子の硬化が早く、能率が向上
する。Forced gas flow from port 1 allows the core to harden quickly, improving efficiency.
へチューブで中子型を完全に包み込むので、ガス洩れが
なく、中子型分割面のシールが不要になる。Since the core mold is completely wrapped in the tube, there is no gas leakage and there is no need to seal the split surface of the core mold.
以上の様に優れた利点を持つこの発明は、多種少量生産
用鋳物中子の通ガス装置として、産業上有益な発明とい
