Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ingot production, in particular to an aluminum ingot demoulding mechanism. Background Art

[0002] In the process of aluminum ingot production, it is first necessary to produce molten aluminum and pour the molten aluminum into the inside of a mold for shaping. Subsequently, after the aluminum ingot is formed, the aluminum ingot is quickly demoulded.

[0003] CN211071747U discloses an aluminum ingot demoulding mechanism. In this demoulding mechanism, a high-pressure water gun is turned on to spray the surface of the aluminum ingot in the cavity. At the same time, a vibrator and a hydraulic cylinder start to work. Cooling water cools the aluminum ingot in the casting mold, enabling the aluminum ingot to be quickly formed. The hydraulic cylinder drives the ejector rod to move up and down linearly and repeatedly, repeatedly knocking on the bottom of the aluminum ingot in the cavity. The vibrator is driven by air pressure or electricity to generate vibration to separate the mold from the aluminum ingot.

[0004] However, the above demoulding mechanism requires the dual cooperation of a vibrator and a hydraulic cylinder. Since the vibrator is arranged inside the casting mold, when multiple casting molds are reciprocally conveyed along with a belt, the cables connected to the vibrator and the oil pipes connected to the hydraulic cylinder will become entangled, resulting in the inability to stably carry out the demoulding work. Summary of the Utility Model

[0032] The embodiment of the present utility model discloses an aluminum ingot demoulding mechanism.

[0033] Embodiment 1

[0034] The present utility model provides as Figures 1-5The shown aluminum ingot demolding mechanism includes a support frame 1. Two drive shafts 2 are rotatably provided at the lower end of the support frame 1. A transmission roller 3 is fixedly sleeved on the outer wall of the drive shaft 2. A transmission belt 4 is jointly sleeved on the roller walls of the two transmission rollers 3. A plurality of spaced forming cavities 5 are fixedly embedded in the interior of the transmission belt 4. A motor 20 is fixedly provided at the lower end of the back side of the support frame 1. The output shaft of the motor 20 penetrates into the support frame 1 and is fixedly connected to the drive shaft 2;

[0035] A cavity is formed inside the forming cavity 5. A cross bar 6 is rotatably provided at the lower end of the inner wall of the cavity. Two symmetrically arranged impact blocks 7 are fixedly sleeved on the rod wall of the cross bar 6. The impact blocks 7 are cam-shaped;

[0036] A bottom knocking mechanism for driving the impact block 7 to swing reciprocally is provided at the middle end of the rod wall of the cross bar 6. The bottom knocking mechanism includes a driving gear 8. A through hole is formed in the lower side of the cavity. A rotating rod 9 is rotatably provided on the inner wall of the through hole. The driving gear 8 is located inside the through hole and is fixedly sleeved with the rotating rod 9. An annular groove 21 for driving the transmission of the driving gear 8 is formed on the roller wall of the transmission roller 3. Torsion springs 10 are sleeved at both ends of the rod wall of the rotating rod 9. The two ends of the torsion spring 10 are respectively fixedly connected to the driving gear 8 and the through hole;

[0037] A transmission gear 11 is fixedly sleeved on the rod wall of the cross bar 6. The transmission gear 11 is arranged in cooperation with the driving gear 8. A cross plate 12 is fixedly provided at the lower end of the support frame 1. A plurality of spaced racks 13 are fixedly provided on the top of the cross plate 12. The driving gear 8 is arranged in cooperation with the racks 13.

[0038] Before the aluminum ingot is formed, the aluminum liquid is poured into the forming cavity 5 to complete the forming of the aluminum ingot. During this process, driven by the motor 20 and the drive rod 2, the transmission roller 3 drives the transmission belt 4 to perform transmission work. At this time, a plurality of forming cavities 5 can move according to the transmission belt 4. When the forming cavity 5 moves, the driving gear 8 meshes with a plurality of racks 13 intermittently. When the driving gear 8 meshes with the rack 13, the driving gear 8 drives the rotating rod 9 to rotate and twist the torsion spring 10. At this time, the meshing drives the transmission gear 11 and drives the cross bar 6 to rotate. At this time, the impact block 7 rotates. When the driving gear 8 is separated from the rack 13, due to the torsion of the torsion spring 10, each component can rotate back and the impact block 7 impacts the lower part of the aluminum ingot forming area. At this time, through the intermittent meshing of the driving gear 8 with a plurality of racks 13, the impact block 7 rotates intermittently to impact the aluminum ingot intermittently, so that the aluminum ingot can be separated from the inner wall of the forming cavity 5 under the vibration action and complete the demolding.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, in order to improve the impact on the aluminum ingot and further improve the demolding effect, as Figure 2As shown in the figure, drive rods 14 are rotatably provided at the upper ends of both inner sides of the cavity. A swing plate 15 is fixedly sleeved on the rod wall of the drive rod 14. The end of the swing plate 15 is in contact and cooperation with the inner wall of the cavity. A side knocking mechanism is provided on the rod wall of the drive rod 14. The side knocking mechanism includes a vertical rod 16. The vertical rod 16 is rotatably connected to the top of the inner wall of the cavity, and a first bevel gear 17 is fixedly sleeved in the middle of the rod wall. A second bevel gear 18 is fixedly sleeved on the rod wall of the drive rod 14. The first bevel gear 17 and the second bevel gear 18 are arranged in cooperation. Third bevel gears 19 are fixedly sleeved at the ends of the vertical rod 16 and the cross bar 6 close to each other. The two third bevel gears 19 are arranged in cooperation.

[0041] When the cross bar 6 rotates, through the meshing of the two third bevel gears 19, the vertical rod 16 rotates synchronously with the cross bar 6. At the same time, through the meshing of the second bevel gear 18 and the first bevel gear 17, the drive rod 14 drives the swing plate 15 to rotate. When the cross bar 6 rotates back under the torsion of the torsion spring 10, the vertical rod 16 and the drive rod 14 rotate back synchronously. At this time, the swing plate 15 can impact the side of the aluminum ingot forming position. Cooperating with the intermittent impact of the impact block 7, the outer side of the aluminum ingot can be comprehensively vibrated and knocked, improving the demoulding effect of the aluminum ingot.

[0042] Embodiment 3

[0043] On the basis of Embodiment 1, in order to stably receive the aluminum ingots that fall off during demoulding in Embodiment 3, as Figure 1 and Figure 5 shown, a guide plate 22 is fixedly provided at the lower end of the side of the support frame 1. The upper end of the guide plate 22 is located below the multiple forming cavities 5. The guide plate 22 is a U-shaped guide plate.

[0044] When the aluminum ingot is separated from the inner wall of the forming cavity 5 due to vibration, when the forming cavity 5 rotates to the side of the conveyor belt 4, the aluminum ingot can fall from the forming cavity 5 and drop into the inside of the guide plate 22. At this time, the guide plate 22 can receive and guide the aluminum ingot, facilitating the collection of the aluminum ingot.

[0045] Embodiment 4

[0046] On the basis of Embodiment 1, in order to improve the demoulding stability in Embodiment 4, as Figure 1 shown, a water tank 23 is fixedly provided at the upper end of the support frame 1. The bottom of the water tank 23 is communicated with a plurality of cooling pipes 24 arranged at intervals. A solenoid valve 25 is fixedly sleeved on the pipe wall of the cooling pipe 24.

[0047] When the aluminum ingot moves horizontally according to the forming cavity 5, through the control of the solenoid valve 25, the cooling water inside the water tank 23 falls through the cooling pipe 24 and contacts the formed aluminum ingot, causing the aluminum ingot to contract by cooling and stably separating from the inner wall of the forming cavity 5, thereby improving the demoulding effect and stability.
