Specific implementation mode

[0031] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] The embodiment of the present utility model discloses an aluminum liquid ingot pouring flow rate adjusting device.

[0033] Embodiment 1

[0034] The present utility model provides an aluminum liquid ingot pouring flow rate adjusting device as shown in Figures 1-6 which includes a pouring groove 1. A cross bar 2 is rotatably inserted through the lower end inside the pouring groove 1. An adjusting plate 3 is fixedly sleeved on the rod wall of the cross bar 2. The adjusting plate 3 is located inside the pouring groove 1. A drive rod 4 is rotatably provided on the outer wall of the pouring groove 1. The inside of the drive rod 4 is hollow. Sprockets 5 are fixedly sleeved on the rod walls of the drive rod 4 and the cross bar 2. A chain 6 is sleeved on the outside of the two sprockets 5 in a driving manner;

[0035] Two symmetrically arranged sliding holes are opened on the side of the drive rod 4. Insertion rods 7 are opened in both of the two sliding holes. The insertion rods 7 are L-shaped. A plurality of insertion slots 8 are opened on the outer wall of the pouring groove 1. The plurality of insertion slots 8 are symmetrically arranged in a surrounding manner along the central axis of the drive rod 4. The insertion rods 7 are inserted and matched with the insertion slots 8. Two symmetrically arranged through holes are opened inside the upper sprocket 5. The insertion rods 7 are located inside the through holes.

[0036] When pouring molten aluminum, the pouring trough 1 can be tilted so that the molten aluminum can fall stably. During the falling process of the molten aluminum, the driving rod 4 can be rotated beside the pouring trough 1 far away. At this time, under the transmission of the two sprockets 5 and the chain 6, the cross bar 2 rotates. At this time, the cross bar 2 can drive the adjusting plate 3 to rotate. At this time, the space between the bottom of the adjusting plate 3 and the inner wall of the pouring trough 1 is adjusted, and the pouring flow rate of the molten aluminum can be adjusted. After the position of the adjusting plate 3 is determined, the position of the driving rod 4 and the cross bar 2 can be fixed by inserting the insertion rod 7 into the insertion slot 8, so as to complete the flow control adjustment.

[0037] Embodiment 2

[0038] On the basis of Embodiment 1, in order to be able to control the insertion rod 7 so that the insertion rod 7 can be stably inserted and matched with the insertion slot 8, as Figures 2-5 shown, a pressing and moving mechanism is arranged between the two insertion rods 7. The pressing and moving mechanism includes two symmetrically arranged cross plates 9. Both cross plates 9 are located in the driving rod 4 and are fixedly connected with the two insertion rods 7;

[0039] Two symmetrically arranged pressing holes are opened on the rod wall of the driving rod 4. A support rod 10 is fixedly arranged on the inner wall of the pressing hole. A pressing rod 11 is rotatably sleeved on the rod wall of the support rod 10. A torsion spring 12 is sleeved on the rod wall of the support rod 10. Two ends of the torsion spring 12 are respectively fixedly connected with the pressing rod 11 and the support rod 10. The pressing rod 11 is arranged in cooperation with the cross plate 9. The pressing rod 11 is an L-shaped pressing rod. Guide inclined surfaces for contacting the pressing rod 11 are opened on one side of the two cross plates 9 away from each other.

[0040] Before rotating the driving rod 4, the driving rod 4 can be held by hand, and the pressing rod 11 can be pressed, so that the pressing rod 11 rotates around the support rod 10 and twists the torsion spring 12. At this time, the end of the pressing rod 11 pushes the guide inclined surface of the cross plate 9. At this time, the two cross plates 9 move horizontally and drive the insertion rod 7 to move horizontally, so that the insertion rod 7 slides in the sliding hole and moves away from the insertion slot 8. At this time, the driving rod 4 can drive the sprocket 5 to rotate, and cooperate with the chain 6 to rotate and adjust the positions of the cross bar 2 and the adjusting plate 3. After the position of the adjusting plate 3 is adjusted, the pressing rod 11 is released, and the insertion rod 7 moves back and is inserted into the insertion slot 8 again through the torsion recovery of the torsion spring 12. At this time, the position of the driving rod 4 can be fixed to ensure the stable progress of the molten aluminum pouring work.

[0041] Embodiment 3

[0042] On the basis of Embodiment 2, in order to enable the insertion rod 7 to move stably horizontally, as Figure 4 shown, sliding rods 13 are fixedly penetrated through one end of the two insertion rods 7 close to each other. The longitudinal section of the sliding rod 13 is rectangular. Sliding grooves for the sliding rods 13 to penetrate through are opened on both sides of the inner wall of the driving rod 4. Springs 14 are fixedly arranged between the sliding rods 13 and the inner walls of the sliding grooves.

[0043] When the cross plate 9 is pushed, through the sliding fit of the sliding rod 13 and the sliding groove, the plug rod 7 can move away from the slot, and at the same time the spring 14 is compressed. After the driving rod 4 rotates, the plug rod 7 can return to its original position by the elastic recovery of the spring 14.

[0044] Example 4

[0045] On the basis of Example 1, in order to enable the pouring groove 1 to rotate stably for pouring molten aluminum, as Figure 1 and Figure 6 shown, a U-shaped frame 15 is sleeved outside the pouring groove 1, and fixed rods 16 are rotatably arranged at the lower ends of both sides of the U-shaped frame 15, and the fixed rods 16 are fixedly connected to the pouring groove 1.

[0046] Before pouring the molten aluminum, the U-shaped frame 15 is fixed at a high place. At this time, the rotation cooperation between the fixed rod 16 and the U-shaped frame 15 can enable the pouring groove 1 to rotate stably and carry out rapid pouring of the molten aluminum.
