Description

A new type of plug rod bottom pouring type molten iron pouring ladle

technical field

The utility model relates to a pouring ladle, in particular to a novel plug rod bottom injection type molten iron pouring ladle.

Background technique

The traditional method of pouring molten iron is to manually use a barrel-shaped ladle. In this way, with the change of the amount of molten iron in the ladle, the tilting angle of the ladle must also change continuously, so the height and flow of molten iron are unstable, resulting in the impact of molten iron on the ladle. The pressure of the sand mold will directly affect the pouring quality. At the same time, manual pouring not only cannot adapt to the rhythm of the high-efficiency and high-speed automatic molding line, but also directly endangers the safety and health of pouring workers due to the harsh working environment. People urgently need a casting ladle with simple operation, stable flow rate and greatly reduced labor intensity.

There is a flow regulating rod connected with the cross rod between the pin shaft and the cylinder. The other end of the cross rod is connected with the plug rod, and the plug rod is vertically arranged in the plug cup directly above the .

The novel plug rod bottom pouring type molten iron casting ladle as described above, wherein, the casting ladle frame is provided with hanging lugs.

The novel stopper rod bottom injection type molten iron ladle as described above, wherein the stopper cup is a round platform or a cylindrical through hole.

As mentioned above, the new stopper rod bottom injection type molten iron pouring ladle, wherein the flow regulating rod is provided with a screw rod, which can be adjusted in height up and down.

In the novel plug rod bottom injection type molten iron pouring ladle as described above, a support rod is provided on the auxiliary support, one end of the support rod is fixed to the auxiliary support, and the other end is provided with a sleeve passing through the plug rod; the cross bar and the sleeve There are springs in between.

In the novel plug rod bottom pouring type molten iron ladle as described above, the end of the plug rod in contact with the plug cup is a spherical or conical structure.

The utility model has the advantages of simple structure, convenient operation, stable flow, rapid opening and closing control, and low price, and can be widely used in high-quality, high-speed, and high-frequency pouring needs of modern automatic casting production lines such as automobiles, compressors, and machinery manufacturing industries.

Detailed ways

As shown in the figure, the utility model includes: a casting bag body and a flow adjustment control mechanism, wherein a casting bag frame 3 is provided on the casting bag body, and the pouring bag frame 3 is fixed to the outer wall 4, and the inner side of the outer wall is provided with a thermal insulation refractory material 5, The bottom of the casting ladle is provided with a plug cup 6, the flow control mechanism is fixed on the auxiliary support 7 connected with the pouring ladle frame 3 and the outer wall 4, the cylinder 8 is vertically fixed on the edge of the auxiliary support 7, the piston rod of the cylinder 8 and the cross bar 11 is connected at one end, the cross bar 11 is connected with the auxiliary bracket 7 through the pin shaft 10, the flow regulating rod 9 at the junction with the cross bar 11 is arranged between the pin shaft 10 and the cylinder 8, the other end of the cross bar 11 is connected with the plug rod 1 Connected, the stopper rod 1 is vertically arranged directly above the stopper cup 6 . The pouring ladle frame 3 is provided with hanging lugs 2; the plug cup 6 is a round platform or a cylindrical through hole; the flow regulating rod 9 is provided with a screw rod, which can be adjusted up and down; the auxiliary support 7 is provided with a support rod 12, and the support rod One end of 12 is fixed with the auxiliary bracket 7, and the other end is provided with a sleeve 14 passing through the stopper rod 1, and a spring 13 is provided between the joint between the cross bar 11 and the stopper rod 1 and the sleeve 14; the stopper rod 1 is in contact with the stopper cup 6 One end is a spherical or a conical structure.

During the use of the utility model, the mouth of the stopper cup 6 is blocked and closed by the spherical head of the stopper rod 1 during the non-pouring state. When the piston of the cylinder 8 moves downward, the stopper rod 1 is pulled up by the cross bar 11, so that the closed stopper rod 1 and the stopper cup 6 are disengaged. The gap of the stopper cup 6 flows out of the inclusion and injects into the sand mold. When pouring is completed, the piston of the cylinder 8 moves upwards to push the stopper rod 1 to move down and contact the stopper cup 6 to form a closure. The pouring process can be realized by controlling the compressed air.
