この考案は、遠心力鋳造機における溶湯(溶融金属)注
入用の鋳込樋内面に、上塗・冷却用液体を流し込むため
の装置の改良に関するものである。[Detailed Description of the Invention] This invention relates to an improvement of a device for pouring a top coating/cooling liquid into the inner surface of a casting trough for pouring molten metal in a centrifugal casting machine.

注入時に鋳型内に流れ込み、鋳造製品の品質を低下させ
る等の種々の弊害がある。By the way, in the Dorabo complete centrifugal casting machine, pipe products are cast by injecting a certain amount of molten metal into a rotating mold. Since this process is carried out using a machine, if this gutter is bent and deformed by the high heat of the molten metal, there is a risk of damaging the vibe during casting, and the top coat layer formed on the inner surface of the gutter may peel off. This reduces the durability of the gutter itself, and if molten metal fragments remain on the inner surface, they will flow into the mold during the next process of pouring the molten metal, causing various problems such as degrading the quality of the cast product. be.
こbため、鋳造機の過熱防止と、樋内面の清掃を目的と
して、該内面□上塗・冷却用の液体を一工程或は数工程
毎に流し込むようにしている。Therefore, in order to prevent overheating of the casting machine and to clean the inner surface of the gutter, a liquid for coating and cooling the inner surface is poured into the gutter every one process or every few processes.
本考案者は、上記した鋳造作業における経験則によって

に短時間で行なうことにより、樋内面の全長にわたって
均一な上塗層の再製(構成)と、そのよシ効果的な冷却
が可能となることを知シ得た。Based on the above-mentioned rule of thumb in casting operations, the inventor of the present invention re-created a uniform top coat layer over the entire length of the inner surface of the gutter by pouring the required amount of top coat/cooling liquid in as short a time as possible. (configuration), we learned that it is possible to achieve more effective cooling.

て回転される鋳型E内に注入されることになる。Accordingly, the casting shoe 1-C is formed to be inclined downward from the starting end toward the terminal end, and a casting machine extending from the terminal end is continuously provided. Therefore, the molten metal injected into the chute C is guided to the casting machine and is injected from the rear end of the gutter into the mold E which is rotated by appropriate power.

る。Reference numeral 6 denotes a supply pipe for the liquid 2, which is also connected to the upper part of the tank 1 via an on-off valve 7, and the chain pipe is connected to the large liquid storage tank 8, which is appropriately provided above the tank 1. The liquid in the dog tank is then passed through the tube 6 to the tank below, e.g. via a float valve or other suitable metering device (not shown), to supply the required amount for coating and cooling the gutter. 1.

の内面を効率良く流下し得る構成を採用してもよい。As shown by the chain line in FIG. 1, the tip opening 11a of the liquid outflow pipe is set at the starting end of the chute C in a state that does not inhibit the tilting of the ladle A and the pouring of molten metal into the casting chute C. The liquid 2 flowing out through the liquid outflow pipe 11 flows into the casting chute C by extending the opening direction thereof into the casting chute C and bending the opening direction along the inclination direction of the chute inner surface.
It is also possible to adopt a configuration that allows the water to flow down the inner surface of the pipe efficiently.

ものである。In the figure, 13, 14, 15 and 16 are the respective valves 4,
7, 10 and 12 are opening/closing operation means such as lunoids, and 17, 18, 19 and 20 indicate operation signals for the means.

は不要である。Therefore, the operation signal can be sent to an appropriate controller arranged to respond to the movement of the mold E to the left or right with respect to the position of the ladle A, or the supply of the liquid 2 into the tank 1, or other operating steps. It may be configured to generate each by using a switch (not shown) or the like, but these valve opening/closing means are unnecessary if each of the valves 4, 7, 10, and 12 is a manual opening/closing valve.

and each valve 4°12 of the liquid outflow pipe 11 is closed, and then,
The signals 18 and 19 open the valves I and 10 of the liquid supply pipe 6 and the air vent pipe 9, and the liquid 2 in the dog tank 8 is further supplied into the tank 1 below through the pipe 6.

とはない。Therefore, when the amount of liquid in the tank 1 reaches the required amount required for one pouring, or when only the required amount is supplied into the tank 1, the valves I and 10 are respectively closed. However, when supplying liquid to tank 1,
Since the valve 10 is open, the inside and outside of the tank can be ventilated, so that the liquid supply function is not inhibited.

When the compressed air 5 is introduced into the tank 1 by simultaneously opening the valves 12 of the and liquid outflow pipes, or by opening the former valve 4 immediately after the latter valve 12, the air causes the liquid 2 in the tank 1 to flow out. The liquid is pressurized and flows through the pipe 11 from its tip opening 11a to the inner surface of the chute C, so that the flowing liquid flows down the inner surface of the chute C and the gutter connected thereto in a short period of time. However, a uniform top coat layer is regenerated over substantially the entire length of the inner surface, foreign matter remaining on the inner surface is removed, and a cooling effect is also performed during the flowing down.

優れた効果がある。As described above, the liquid pouring device according to the present invention includes a tank capable of accommodating the required amount of liquid for coating and cooling the inner surface of the casting trough, and a tank connected to the upper part of the tank via an on-off valve. It consists of a compressed air inlet pipe, the liquid supply pipe, the air vent pipe, and a liquid outflow pipe connected to the lower part of the tank via an on-off valve, and the tip opening of the liquid outflow pipe is placed near the top of the casting chute. According to the device of the present invention, the functions of supplying liquid into the tank, venting air, introducing compressed air, and draining liquid from the tank can be performed by simply opening and closing the valves. This eliminates the need for conventional equipment of this type, such as the need for an opening/closing device using a hydraulic cylinder for the opening/closing lid of a liquid storage tank, or the complicated piping for a liquid outflow pipe. The overall structure and operation can be simplified, and the device can be provided at a low cost.Additionally, by opening the valve of the air vent pipe, the liquid can be smoothly supplied into the tank. It has excellent effects such as being able to perform liquid pouring with an extremely simple operation, and being particularly suitable as a liquid pouring device for high-efficiency production.
