Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot production technology, and more specifically, to a uniform aluminum liquid injection device for aluminum ingot production. Background Technology

[0002] During the casting process, aluminum ingots need to be molten aluminum poured into a mold to form the ingot. Usually, the molten aluminum is poured into one end of the mold, which results in the surface of the aluminum ingot near the pouring end being higher than the other end. This causes uneven mass distribution and affects the quality of the finished product. Therefore, an injection molding device is needed to evenly pour the molten aluminum into the mold.

[0003] Common aluminum ingot production aluminum molten metal uniform injection devices can only uniformly inject aluminum molten metal into the mold, but lack the function of limiting the injection path. In actual operation, it is necessary to adjust the lifting structure such as telescopic rods or racks to change the height of the injection nozzle to match the mold height. However, when the telescopic rods or racks are extended, the liquid storage tank will shake due to the inertia during the displacement process and the existence of assembly gaps. The shaking liquid storage tank will then cause the injection nozzle to deviate, thereby disrupting the uniformity of aluminum molten metal distribution in the mold. The deviated aluminum molten metal flow will impact the mold edge, parting surface or other non-gate areas, causing aluminum molten metal to splash everywhere, ultimately leading to the problem of low quality of finished aluminum ingots.

[0004] In summary, to ensure the quality of finished aluminum ingots, it is necessary to address the issue of nozzle misalignment, ensuring that the liquid storage tank can inject liquid along a designated path when moving the nozzle. Utility Model Content

[0005] The present invention provides a uniform aluminum liquid injection device for aluminum ingot production. The problem to be solved is that when the lifting structure such as telescopic rod or rack is extended, the liquid storage tank shakes due to displacement inertia and assembly gap, which in turn causes the injection nozzle to deviate. This deviation disrupts the uniformity of aluminum liquid distribution in the mold, causing the aluminum liquid to impact the mold edge, parting surface or non-gate area, resulting in splashing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a uniform aluminum liquid injection device for aluminum ingot production, comprising a mold base plate, a mold groove at the upper end of the mold base plate, two sets of vertical sliding rods installed at the upper end of the mold base plate, a horizontal displacement power mechanism on the two sets of vertical sliding rods, a height adjustment mechanism on the horizontal displacement power mechanism, the output end of the horizontal displacement power mechanism being connected to the height adjustment mechanism, a liquid storage tank on the height adjustment mechanism, the horizontal displacement power mechanism being used to control the horizontal displacement of the liquid storage tank, the output end of the height adjustment mechanism being connected to the liquid storage tank, the height adjustment mechanism being used to control the lifting and lowering movement of the liquid storage tank, two wheel frames symmetrically installed on the surface of the liquid storage tank, multiple pulleys rotatably connected to the inner side of the wheel frames, two limiting frames being provided between the two sets of vertical sliding rods, the two wheel frames being respectively inserted into the interior of the two limiting frames, two fixing bolts being installed on the surface of the limiting frames, a slider being installed at the end of the fixing bolt near the vertical sliding rod, the slider being slidably connected to the vertical sliding rod, and an aluminum liquid supply and discharge assembly being provided on the liquid storage tank, the aluminum liquid supply and discharge assembly being used to discharge the aluminum liquid input into the liquid storage tank.

[0007] In a preferred embodiment, the horizontal displacement power mechanism includes a drive component and an anti-rotation component. The output end of the drive component is connected to the height adjustment mechanism, and the drive component is used to control the horizontal displacement of the height adjustment mechanism. The sliding end of the anti-rotation component is connected to the height adjustment mechanism, and the anti-rotation component is used to prevent the liquid storage tank from rotating with the drive component.

[0008] In a preferred embodiment, the anti-rotation assembly includes a fixing block mounted on the upper end of two sets of vertical sliding rods, a top plate mounted between the two fixing blocks, a partition plate mounted on the lower end of the top plate, and two horizontal sliding rods mounted between the partition plate and the right-side fixing block.

[0009] In a preferred embodiment, the drive assembly includes a motor mounted on the surface of the left fixed block and a lead screw mounted on the output end of the motor, the motor being used to control the rotational movement of the lead screw.

[0010] In a preferred embodiment, the height adjustment mechanism includes a linkage component and a lifting component. The output end of the linkage component is connected to the lifting component, and the linkage component is used to control the horizontal displacement of the liquid storage tank. The output end of the lifting component is connected to the liquid storage tank, and the lifting component is used to control the lifting movement of the liquid storage tank.

[0011] In a preferred embodiment, the linkage component includes a displacement block disposed between the partition plate and the right-side fixed block and a connecting plate installed at the lower end of the displacement block. The displacement block is slidably connected to the horizontal slide bar and threadedly connected to the lead screw.

[0012] In a preferred embodiment, the lifting assembly includes an electric telescopic rod installed at the lower end of the connecting plate and four mechanical telescopic rods installed at the lower end of the connecting plate. The lower ends of the electric telescopic rods are fixedly connected to the liquid storage tank, and the lower ends of the mechanical telescopic rods are fixedly connected to the liquid storage tank.

[0013] In a preferred embodiment, the aluminum liquid supply and discharge assembly includes two infusion pipes installed at the upper end of the liquid storage tank and a strip nozzle installed at the lower end of the liquid storage tank.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention effectively eliminates the offset problem of the liquid storage tank and the strip nozzle in traditional devices through multiple structural designs. Specifically, the pulley frames symmetrically installed on both sides of the liquid storage tank are precisely engaged inside the limiting frame, allowing the pulleys to roll along the inner wall of the limiting frame. This rigid constraint significantly suppresses radial swaying caused by inertia or assembly gaps when the liquid storage tank moves horizontally. At the same time, the limiting frame achieves synchronous lifting and lowering through the sliding connection between the slider and the vertical slide rod, ensuring that the limiting frame always provides stable horizontal guidance for the pulley frames regardless of the height of the liquid storage tank. The synergistic effect of the above structures ensures that the strip nozzle always moves accurately and smoothly along the predetermined trajectory, completely avoiding splashing caused by the liquid flow offset impacting the non-gate area of ​​the mold. This fundamentally ensures the uniformity of aluminum liquid distribution within the mold, thereby significantly improving the quality consistency of aluminum ingot forming.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Refer to the instruction manual appendix Figures 1 to 5 A uniform aluminum liquid injection device for aluminum ingot production includes a mold base plate 1. A mold groove 11 is formed at the upper end of the mold base plate 1. Two sets of vertical sliding rods 12 are installed at the upper end of the mold base plate 1. A horizontal displacement power mechanism is installed on the two sets of vertical sliding rods 12. A height adjustment mechanism is installed on the horizontal displacement power mechanism. The output end of the horizontal displacement power mechanism is connected to the height adjustment mechanism. A liquid storage tank 13 is installed on the height adjustment mechanism. The horizontal displacement power mechanism is used to control the horizontal displacement of the liquid storage tank 13. The output end of the height adjustment mechanism is connected to the liquid storage tank 13. To control the lifting and lowering movement of the liquid storage tank 13, two wheel frames 14 are symmetrically installed on the surface of the liquid storage tank 13. Multiple pulleys 15 are rotatably connected to the inner side of the wheel frames 14. Two limit frames 17 are set between the two sets of vertical slide rods 12. The two wheel frames 14 are respectively inserted into the two limit frames 17. Two fixing bolts 18 are installed on the surface of the limit frames 17. A slider 16 is installed at the end of the fixing bolt 18 near the vertical slide rod 12. The slider 16 is slidably connected to the vertical slide rod 12. An aluminum liquid supply and discharge assembly is provided on the liquid storage tank 13. The aluminum liquid supply and discharge assembly is used to discharge the aluminum liquid input into the liquid storage tank 13.

[0024] It should be noted that when the liquid storage tank 13 moves horizontally, the pulley 15 rolls along the inner wall of the limiting frame 17 to reduce the friction during horizontal displacement. The limiting frame 17 then limits the position of the wheel frame 14, thereby preventing radial swaying caused by inertia or assembly gaps in the traditional lifting mechanism and suppressing the lateral displacement of the strip nozzle 412. At the same time, the limiting frame 17 is slidably connected to the vertical slide rod 12 through the slider 16, so that it can slide synchronously along the vertical slide rod 12 as the liquid storage tank 13 moves horizontally.

[0025] It is worth noting that this structural design ensures that regardless of the height of the liquid storage tank 13, the limiting frame 17 always applies a horizontal constraint to the wheel frame 14 and the pulley 15 inside it through the slider 16 along the guide of the vertical slide bar 12. This constraint effectively suppresses the shaking or displacement of the liquid storage tank 13 during horizontal movement, ensuring that the liquid storage tank 13 and the strip nozzle 412 at its lower end can maintain positional stability during horizontal movement.

[0026] Refer to the instruction manual appendix Figures 1 to 2The horizontal displacement power mechanism includes a drive component and an anti-rotation component. The output end of the drive component is connected to the height adjustment mechanism, and the drive component is used to control the horizontal displacement of the height adjustment mechanism. The sliding end of the anti-rotation component is connected to the height adjustment mechanism, and the anti-rotation component is used to prevent the liquid storage tank 13 from rotating with the drive component.

[0027] It should be noted that although the lead screw 222 can provide precise linear displacement, its rotational motion characteristics can easily cause the threaded components to rotate. The anti-rotation component, through the constraint of the slide bar 214, forces the displacement block 311 to move only along the axial direction, thereby converting the rotational motion of the lead screw 222 into pure linear motion.

[0028] Refer to the instruction manual appendix Figure 2 The anti-rotation component includes a fixing block 211 installed on the upper end of two sets of vertical sliding rods 12, a top plate 212 installed between the two fixing blocks 211, a partition plate 213 installed on the lower end of the top plate 212, and two horizontal sliding rods 214 installed between the partition plate 213 and the right-side fixing block 211.

[0029] It should be noted that the arrangement of the two parallel horizontal sliding rods 214 significantly improves the anti-torsional stiffness and stability, ensuring that the displacement block 311 can only move in the horizontal direction under the drive of the lead screw 222, effectively eliminating any potential rotational degrees of freedom.

[0030] Refer to the instruction manual appendix Figure 2 The drive assembly includes a motor 221 mounted on the surface of the left fixed block 211 and a lead screw 222 mounted on the output end of the motor 221. The motor 221 is used to control the rotational movement of the lead screw 222.

[0031] It should be noted that the motor 221 serves as the power source, and its output shaft directly drives the lead screw 222 to rotate. The lead screw 222 transmission has advantages such as high transmission efficiency, high positioning accuracy, and self-locking capability. The rotating lead screw 222 drives the displacement block 311 to move left and right in the horizontal direction.

[0032] Refer to the instruction manual appendix Figures 1 to 3 The height adjustment mechanism includes a linkage component and a lifting component. The output end of the linkage component is connected to the lifting component. The linkage component is used to control the horizontal displacement of the liquid storage tank 13. The output end of the lifting component is connected to the liquid storage tank 13. The lifting component is used to control the lifting movement of the liquid storage tank 13.

[0033] It should be noted that the linkage component synchronously transmits the horizontal displacement generated by the horizontal displacement power mechanism to the lifting component and the liquid storage tank 13, while the lifting component independently controls the position of the liquid storage tank 13 in the vertical direction.

[0034] It is worth noting that this design achieves decoupled control of the horizontal movement and vertical lifting of the liquid storage tank 13. The horizontal movement is achieved by the linkage component driven by the horizontal displacement power mechanism, while the lifting is driven independently by the lifting component. The two do not interfere with each other and the operation is flexible.

[0035] Refer to the instruction manual appendix Figure 3 The linkage component includes a displacement block 311 disposed between the partition plate 213 and the right fixed block 211 and a connecting plate 312 installed at the lower end of the displacement block 311. The displacement block 311 is slidably connected to the horizontal slide bar 214 and threadedly connected to the lead screw 222.

[0036] It should be noted that the threaded connection between the displacement block 311 and the lead screw 222 converts the rotational motion into linear motion, while the sliding connection with the transverse slide bar 214 ensures that the converted motion is a strictly linear translation. The connecting plate 312 reliably transmits this translation to the lifting assembly below.

[0037] Refer to the instruction manual appendix Figure 3 The lifting assembly includes an electric telescopic rod 321 installed at the lower end of the connecting plate 312 and four mechanical telescopic rods 322 installed at the lower end of the connecting plate 312. The lower end of the electric telescopic rod 321 is fixedly connected to the liquid storage tank 13, and the lower end of the mechanical telescopic rods 322 is fixedly connected to the liquid storage tank 13.

[0038] It should be noted that the electric telescopic rod 321 is the main actuator and power source for the lifting movement, providing pushing and pulling force. The four mechanical telescopic rods 322 are symmetrically distributed around the electric telescopic rod 321 in a rectangular arrangement. Their function is to provide stable guidance and support for the liquid storage tank 13. When the electric telescopic rod 321 extends or retracts, the four mechanical telescopic rods 322 follow the liquid storage tank 13 to extend or retract in the vertical direction.

[0039] Refer to the instruction manual appendix Figures 1 to 4 The aluminum liquid supply and discharge assembly includes two liquid delivery pipes 411 installed at the upper end of the liquid storage tank 13 and a strip nozzle 412 installed at the lower end of the liquid storage tank 13.

[0040] It should be noted that the two infusion pipes 411 are connected to external infusion equipment to input molten aluminum into the storage tank 13, and the strip nozzle 412 is the final outlet for the molten aluminum, and its length direction is usually parallel to the length direction of the mold.

[0041] Working principle: First, the injection height needs to be adjusted. The electric telescopic rod 321 of the height adjustment mechanism is activated, causing the storage tank 13 to rise and fall vertically. Simultaneously, the four mechanical telescopic rods 322 extend and retract synchronously. The limiting frame 17, connected to the slider 16 via the fixing bolt 18, slides with the vertical sliding rod 12, allowing the limiting frame 17 to move horizontally synchronously with the storage tank 13. Then, molten aluminum is delivered to the infusion pipe 411 via an external infusion device, and then injected into the storage tank 13 through the infusion pipe 411. At the same time, the motor 221 of the horizontal displacement power mechanism starts, driving the lead screw 222 to rotate. Because the displacement block 311 is threadedly connected to the lead screw 222 and is subject to the sliding constraint of the horizontal sliding rod 214, the rotational motion of the lead screw 222 is converted into the horizontal linear displacement of the displacement block 311, which is then transmitted through the connecting plate 31. 2. The liquid storage tank 13 is moved horizontally. During this process, the wheel frames 14 on both sides of the liquid storage tank 13 and the pulleys 15 inside are embedded in the limiting frame 17, so that the pulleys 15 roll along the inner wall of the limiting frame 17 to reduce friction. The rigid constraint of the limiting frame 17 on the wheel frames 14 effectively suppresses the radial shaking of the liquid storage tank 13 caused by inertia or assembly gap, ensuring that the liquid storage tank 13 always moves smoothly along the predetermined path. During the movement of the liquid storage tank 13, the strip nozzle 412 at its bottom injects liquid evenly into the mold in the mold placement groove 11. The length direction of the strip nozzle 412 is consistent with the length of the mold. Combined with the horizontal uniform movement of the liquid storage tank 13, the aluminum liquid is evenly distributed along the entire length of the mold, avoiding the problem of aluminum liquid splashing or uneven quality caused by the position displacement of the strip nozzle 412, and finally improving the quality consistency of aluminum ingot forming.

[0042] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
