Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1 - Figure 4As shown, this utility model provides a technical solution for a casting nozzle clamping device for aluminum alloy plates, including a clamp body 1 and a mounting frame 2. The mounting frame 2 is fixedly connected to the top of the clamp body 1. Two reinforcing plates 201 are fixedly connected to the top of the mounting frame 2. The two reinforcing plates 201 are symmetrically distributed with respect to the vertical center line of the mounting frame 2. Two through holes 200 are opened on the outer side of the mounting frame 2. A placement groove 3 is opened on the top of the mounting frame 2. Connecting grooves 4 are formed on both sides inside the placement groove 3. Sliding grooves 5 are formed at the bottom of the two connecting grooves 4. A mounting plate 6 is provided inside the placement groove 3. Connecting blocks 7 are fixedly connected to both sides of the mounting plate 6. The two connecting blocks 7 are respectively set inside the two connecting grooves 4 and slidably connected to the mounting frame 2. Moving blocks 8 are fixedly connected to the bottom of the two connecting blocks 7. The two moving blocks 8 pass through the two sliding grooves 5 respectively. The inner side of the two moving blocks 8 is threaded with a first threaded rod 9. The outer ends of the two first threaded rods 9 are rotatably connected with support blocks 1. 0. The tops of multiple support blocks 10 are fixedly connected to the mounting frame 2. One end of each of the two first threaded rods 9 is fixedly connected to a sprocket 14. The two sprockets 14 are connected by a chain drive. One of the first threaded rods 9 is provided with a first worm gear 11 and a first worm 12 on its outer side. The first worm gear 11 is fixedly connected to the outer side of one of the first threaded rods 9. The first worm 12 is meshed with the outer side of the first worm gear 11. Both ends of the outer side of the first worm 12 are rotatably connected to a first support block 13. The tops of the two first support blocks 13 are fixedly connected to the mounting frame 2. One end of the first worm 12 is equipped with a first throttle. The bottom of the mounting plate 6 is fixedly connected to multiple L-shaped fixing plates 15. One end of each of the multiple L-shaped fixing plates 15 is fixedly connected to a U-shaped seat 16. One side of the clamp body 1 has multiple adapter slots 100. Multiple U-shaped seats 16 are respectively set inside the multiple adapter slots 100. A clamp 17 is rotatably connected inside the U-shaped seat 16. An adjustment structure is provided on the outer side of the clamp 17.

[0023] Specifically, by rotating the first throttle, the first worm gear 12 meshes with the first worm wheel 11, and one of the first threaded rods 9 drives one of the sprockets 14 to rotate. One of the sprockets 14 and the other sprocket 14 are driven by a chain, so that the two first threaded rods 9 rotate simultaneously. The two first threaded rods 9 are threadedly connected to two moving blocks 8 respectively. The two moving blocks 8 drive the mounting plate 6 to move outward from the placement slot 3 through two connecting blocks 7 respectively. The mounting plate 6 drives multiple second threaded rods 23 to move, and drives multiple clamps 17 on the U-shaped seat 16 to move through multiple L-shaped fixing plates 15. Therefore, multiple clamps 17 are moved away from the casting nozzle at the same time, so that personnel can disassemble the casting nozzle.

[0024] Example: Figure 1 - Figure 4As shown, the adjustment structure includes an inclined groove 18 and a connecting groove 19. The inclined groove 18 is formed inside the clamp 17, and the connecting groove 19 is opened on one side of the clamp 17. The connecting groove 19 communicates with the inclined groove 18.

A second worm gear 22 is fixedly connected to the top end of the second threaded rod 23. A second worm 220 is meshed with the outside of the second worm gear 22. A second support block 221 is rotatably connected to both ends of the outside of the second worm 220. Both second support blocks 221 are fixedly connected to the top of the mounting frame 2. A second throttle is installed at one end of the second worm 220.

[0025] Specifically, when the second throttle is turned, the second worm 220 meshes with the second worm wheel 22. The second worm wheel 22 drives the second threaded rod 23 to rotate. The second threaded rod 23 is threadedly connected to the adjusting plate 21. The adjusting plate 21 moves downward. At this time, the sliding column 20 set at one end of the adjusting plate 21 slides inside the inclined groove 18, so the opening degree of the clamp 17 can be adjusted. The setting of the second worm wheel 22 and the second worm 220 has a certain locking effect and improves the stability of the clamp 17.
