Problems solved by technology

[0002] Die-casting moulds, the molten steel in the mold-casting area needs to be poured into the mold after being treated in the RH furnace. The equipment has the following defects in use: There is a phenomenon of contact with air between the casting port and the ladle outlet. The temperature of the molten steel is high, and the temperature of the surrounding air is low. During the heat exchange process, a large air flow is generated. As the casting progresses, the air will be brought into the molten steel, affecting The composition of molten steel will cause the ingot to be scrapped, thus affecting the casting quality

Embodiment Construction

[0019] Below with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between the various parts, the role and working principle of the various parts, etc., will be further described. Detailed instructions:

[0020] as attached figure 1 , attached figure 2 As shown, the present invention is an argon blowing protection device for a mold casting mold. The argon blowing protection device for a mold casting mold includes an argon gas source 1, a sealing ring 2, and a hollow annular cavity 3 is arranged inside the sealing ring 2. The argon gas source 1 communicates with the annular cavity 3 of the sealing ring 2 through the connecting pipe 4, the sealing ring 2 is set above the casting nozzle 5, the connecting pipe 4 is provided with a throttle valve 6 for adjustment, and the annular cavity 3 is provided with Gas outlet gap 1...

Abstract

The invention provides an argon blowing protection device which is used for a die-casting die and applied to the technical field of auxiliary components for die-casting dies. A circular cavity (3) is formed inside a plugging ring (2) of the argon blowing protection device for the die-casting die; an argon source (1) communicates with the circular cavity (3) by the aid of a connecting pipeline (4); the position above a casting gate (5) is sleeved with the plugging ring (2); a throttling valve (6) for adjustment is arranged on the connecting pipeline (4); and a gas outlet gap (10) for outputting argon is formed in the circular cavity (3). The device is simple in structure and low in manufacturing cost and can provide argon for the casting gate in the molten steel pouring process, continuous high-pressure argon exists at the casting gate part, outside air cannot get close to the casting gate, molten steel is prevented from making contact with the air, steel ingots cannot be scrapped due to the effect of impurities in the air, and the steel smelting quality is improved.

Description

technical field [0001] The invention belongs to the technical field of mold auxiliary parts, and more specifically relates to an argon blowing protection device for a mold. Background technique [0002] Die-casting moulds, the molten steel in the mold-casting area needs to be poured into the mold after being treated in the RH furnace. The equipment has the following defects in use: There is a phenomenon of contact with air between the casting port and the ladle outlet. The temperature of the molten steel is high, and the temperature of the surrounding air is low. During the heat exchange process, a large air flow is generated. As the casting progresses, the air will be brought into the molten steel, affecting The composition of molten steel will cause the ingot to be scrapped, thus affecting the casting quality. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the deficiencies of the prior art, provide a simple s...
