[0007] (II) Technical Solution

[0008] To achieve the advantages of completely stopping the discharge of molten metal without affecting the control of the molten metal discharge rate, and blocking the opening of the casting nozzle body when not in use, the specific technical solution adopted by this utility model is as follows:

[0009] A casting nozzle structure for aluminum casting and rolling includes a casting nozzle body and a control panel. A first tee pipe is fixedly inserted through the front end face of the casting nozzle body, and second tee pipes are installed at both ends of the first tee pipe. Multiple flow dividers are fixedly inserted inside the casting nozzle body, and electric heating rods are inserted inside each of the multiple flow dividers. A cover plate is installed at the rear of the casting nozzle body. A heat insulation plate is fixedly inserted through the side wall of the first tee pipe, and an electric telescopic rod is installed on the front end face of the heat insulation plate. A heat insulation rod is installed at the telescopic end of the electric telescopic rod.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a casting nozzle structure for aluminum casting and rolling, which has the following beneficial effects:

[0017] (1) This utility model adopts a first three-way pipe and a second three-way pipe. When actually using the casting nozzle structure for aluminum casting and rolling, one end of the second three-way pipe is connected to the outlet of the external liquid storage structure. Using the control panel, multiple sets of electric heating rods are powered on. When the casting nozzle body is tilted, the aluminum liquid can enter the interior of the casting nozzle body through the second three-way pipe and the first three-way pipe. Multiple flow blocks can divert the aluminum liquid. Finally, the aluminum liquid can fall into the casting and rolling mill through the casting nozzle body. During this process, the electric telescopic rod can be extended and retracted using the control panel. The position of the plug can be adjusted by the heat insulation rod. The aluminum liquid can flow out through the gap between the first three-way pipe and the plug. Therefore, adjusting the position of the plug can adjust the discharge volume of the aluminum liquid. When the plug blocks the remaining end of the first three-way pipe, the aluminum liquid cannot enter the interior of the casting nozzle body. By setting the first three-way pipe and the second three-way pipe, the discharge of the metal liquid can be completely stopped without affecting the control of the metal liquid discharge volume, thus improving the practicality of the casting nozzle structure for aluminum casting and rolling.

[0018] (2) This utility model uses a cover plate. Before actually using the aluminum casting nozzle structure, the operator manually moves two sets of T-shaped rods backward. When the cover plate moves out of the opening of the nozzle body, the connecting plate is rotated around the mounting screw as the central axis, which can drive the cover plate to rotate. When the cover plate is rotated to the appropriate position, the operator manually rotates the two sets of mounting nuts clockwise and counterclockwise by using the mounting screw and the two sets of mounting nuts in mutual engagement. When the two sets of mounting nuts are in close contact with the right set of concave seats, the use position of the cover plate is fixed. At this time, the cover plate will not affect the discharge of aluminum liquid. After use, the operator rotates the two sets of mounting nuts in the opposite direction, and then rotates the connecting plate again around the mounting screw as the central axis. After the cover plate is reset, the connecting screw passes through the left set of concave seats, and then the connecting screw is used to... The connecting screw and the connecting nut are threaded together. The operator rotates the connecting nut clockwise by hand. When the connecting nut is in close contact with the set of concave seats on the left, the connection of the cover plate is completed. At this time, the two sets of T-shaped rods are moved forward. When the cover plate is inserted into the opening of the casting nozzle body, the two sets of threaded through holes and the two sets of mounting bolts are engaged. The operator rotates the two sets of mounting bolts clockwise by hand. When one end of the two sets of mounting bolts moves into the two sets of insertion holes, the position of the cover plate is fixed. At this time, the cover plate blocks the opening of the casting body, preventing impurities from entering the interior of the casting nozzle body. The operator needs to wear heat-resistant gloves for manual operation. The cover plate can block the opening of the casting nozzle body when not in use, ensuring the continuous use of the casting nozzle structure for aluminum casting. Attached Figure Description

By setting the first tee pipe 2 and the second tee pipe 3, the discharge of molten metal can be completely stopped without affecting the control of the discharge volume of molten metal, thereby improving the practicality of the aluminum casting nozzle structure.

[0030] In one embodiment, a concave frame 11 is installed at the lower part of the casting nozzle body 1, and two sets of T-shaped rods 12 slide through the front end of the concave frame 11. Multiple sets of insertion holes 14 are opened on the side walls of the two sets of T-shaped rods 12. Threaded through holes 21 are provided on both sides of the concave frame 11, and mounting bolts 15 are provided inside the two sets of threaded through holes 21. A concave seat 13 is installed at one end of each set of T-shaped rods 12.

[0032] In one embodiment, the two sets of threaded through holes 21 and the two sets of mounting bolts 15 are threadedly engaged with each other, which facilitates the adjustment of the usage position of the two sets of mounting bolts 15.

[0033] In one embodiment, the mounting screw 18 and the two sets of mounting nuts 20 are threaded together to facilitate adjustment of the usage position of the two sets of mounting nuts 20.

[0034] In one embodiment, the control panel is electrically connected to multiple sets of electric heating rods 5 and electric telescopic rods 8 via wires. The control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0035] Working principle:

[0036] In actual use of the aluminum casting nozzle structure, one end of the second three-way pipe 3 is connected to the outlet of the external liquid storage structure. Using the control panel, multiple sets of electric heating rods 5 are energized. When the nozzle body 1 is tilted, molten aluminum can enter the interior of the nozzle body 1 through the second three-way pipe 3 and the first three-way pipe 2. Multiple flow dividers 4 can divert the molten aluminum, and finally, the molten aluminum can fall into the casting and rolling mill through the nozzle body 1. During this process, the electric telescopic rod 8 can be extended and retracted using the control panel, and the position of the plug 10 can be adjusted via the heat insulation rod 9. Molten aluminum can flow out through the gap between the first three-way pipe 2 and the plug 10. Therefore, adjusting the position of the plug 10 can adjust the discharge rate of the molten aluminum. When the remaining end of the first three-way pipe 2 is blocked by the head 10, the molten aluminum cannot enter the interior of the casting nozzle body 1. Through the first three-way pipe 2 and the second three-way pipe 3, the discharge of molten metal can be completely stopped without affecting the control of the molten metal discharge rate, thus improving the practicality of the casting nozzle structure for aluminum casting and rolling. Furthermore, before actually using the casting nozzle structure for aluminum casting and rolling, the operator manually moves the two sets of T-shaped rods 12 backward. When the cover plate 6 moves out of the opening of the casting nozzle body 1, the sleeve plate 19 is rotated around the mounting screw 18 as the central axis, which can drive the cover plate 6 to rotate. When the cover plate 6 rotates to the appropriate position, the operation is completed by utilizing the interlocking threads of the mounting screw 18 and the two sets of mounting nuts 20. The worker manually rotates the two sets of mounting nuts 20 clockwise and counterclockwise. When the two sets of mounting nuts 20 are in close contact with the right-side concave seat 13, the position of the cover plate 6 is fixed. At this time, the cover plate 6 will not affect the discharge of molten aluminum. After use, the operator rotates the two sets of mounting nuts 20 in the opposite direction. Then, the operator rotates the sleeve plate 19 again around the mounting screw 18 as the central axis. After the cover plate 6 is reset, the connecting screw 16 passes through the left-side concave seat 13. Then, using the threaded engagement of the connecting screw 16 and the connecting nut 17, the operator manually rotates the connecting nut 17 clockwise. When the connecting nut 17 is in close contact with the left-side concave seat 13, the cover plate is now in place. During the connection of plate 6, two sets of T-shaped rods 12 are moved forward. When the cover plate 6 is inserted into the opening of the casting nozzle body 1, the two sets of threaded through holes 21 and two sets of mounting bolts 15 are engaged with each other. The operator rotates the two sets of mounting bolts 15 clockwise by hand. When one end of the two sets of mounting bolts 15 moves into the two sets of insertion holes 14, the position of the cover plate 6 is fixed. At this time, the cover plate 6 blocks the opening of the casting body, and impurities cannot enter the interior of the casting nozzle body 1. The operator needs to wear heat-resistant gloves for manual operation. With the cover plate 6, the opening of the casting nozzle body 1 can be blocked when not in use, which ensures the continuous use of the casting nozzle structure for aluminum casting.
