Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy processing. Specifically, it particularly relates to an automatic high-density die-casting forming machine for aluminum alloy die-castings. Background Art

[0002] Aluminum alloy is an alloy with aluminum as the base and a certain amount of other alloying elements added, and it is one of the light metal materials; die-casting is a precision casting method that uses high pressure to force molten metal into a metal mold with a complex shape. When die-casting aluminum alloy materials, a die-casting forming machine is required.

[0003] In Chinese Patent CN220574711 U, an aluminum alloy casting continuous die-casting forming device is disclosed, which relates to the technical field of aluminum alloy casting processing. The aluminum alloy casting continuous die-casting forming device includes a support plate and a workbench. A driving motor for driving a driving belt outside a driving rod is screwed and fixed inside the workbench. A driving rod for driving a mold on a placement plate to rotate is sleeved inside the driving belt. A groove for improving the rotation stability of the placement plate is opened on the surface of the workbench. A fixing ring is welded on the outside of the placement plate, and the fixing ring slides in a fixing groove opened inside the groove. A slider is welded at the bottom of the placement plate, and the slider slides in a sliding groove opened at the bottom of the groove. A cylinder for driving an installation plate on a guide rod to move is screwed and fixed inside the support plate. A pressing mold for die-casting aluminum alloy casting materials is screwed and fixed inside the installation plate.

[0004] When the existing aluminum alloy casting continuous die-casting forming device is in use, usually after die-casting the aluminum alloy casting materials, workers need to take out the die-cast aluminum alloy castings, and then place the aluminum alloy casting materials on the mold for die-casting treatment. The steps are cumbersome, which affects the die-casting efficiency of the aluminum alloy castings. In the above document, multiple groups of molds are provided on the placement plate, and the placement plate drives the molds to rotate so that different molds can move below the pressing mold, so as to take out the die-cast completed castings without affecting normal die-casting. However, since the formed castings are located inside the mold, when taking out the castings, the pressing mold will normally move downward for die-casting, which is somewhat dangerous for workers and inconvenient to take out the castings.

[0005] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0006] Regarding the problems in the related art, the utility model proposes an automatic high-density die-casting forming machine for aluminum alloy die-castings to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model relates to an automatic high-density die-casting forming machine for aluminum alloy die-castings, which includes a rotating table. A die cavity is formed on the outer surface of the rotating table. A blanking component is arranged inside the rotating table. A driving component and a supporting component are arranged at the bottom of the rotating table. A pressing-down component is arranged on the top of the rotating table. The blanking component is used to help the casting break out of the die cavity. The driving component is used to drive the rotating table to rotate. The pressing-down component is used to cooperate with the die cavity for die-casting.

[0009] Further, the blanking component includes a sliding rod. One end of the sliding rod is fixedly connected with a limiting plate. The other end of the sliding rod is fixedly connected with a sliding plate. A round rod is fixedly connected to the bottom of the sliding plate.

Both the sliding rod and the limiting plate are slidably connected with the rotating table. The sliding plate is slidably connected with the die cavity.

[0010] Further, the driving component includes a support. The support is fixedly connected to the bottom of the supporting component. A motor is fixedly connected to the outer surface of the support. A first gear is rotatably connected to the output shaft of the motor. A second gear is meshed with the outer surface of the first gear. A rotating shaft is fixedly connected to the outer surface of the second gear. The rotating shaft is fixedly connected with the rotating table. Both the first gear and the second gear are rotatably connected inside the supporting component.

[0011] Further, the pressing-down component includes an electric push rod. A pressing plate is fixedly connected to the movable end of the electric push rod. A die is fixedly connected to the bottom of the pressing plate. An injection hole is formed on the top of the pressing plate. The die is used to cooperate with the die cavity.

[0012] Further, the supporting component includes a square platform. A bracket is fixedly connected to the top of the square platform. A top plate is fixedly connected to the top of the bracket.

[0014] Further, a round plate is fixedly connected to the end of the leg.

[0015] The utility model has the following beneficial effects:

[0016] 1. Through the connection between the blanking component and the driving component, the driving component drives the rotating table and the mold cavity to rotate. During the rotation, the blanking component automatically retracts, separating the blanking component from the casting in the mold cavity. At this time, the casting is no longer extruded and fixed by the blanking component, and the casting can fall out of the mold cavity under the action of gravity and land below the supporting component, thus realizing automatic demolding without the need for staff to manually take out the casting, which is relatively convenient to use.

[0017] 2. Through the connection between the sliding plate and the rotating shaft, the rotating shaft drives the rotating table and the mold cavity to rotate. During the rotation of the rotating table, the round rod at the bottom of the sliding plate will move along the arc-shaped groove. When the round rod moves to the blanking port, the round rod separates from the arc-shaped groove, and the arc-shaped groove no longer restricts the round rod. At this time, the spring can pull the sliding plate and the round rod to move, making the sliding plate move away from the casting in the mold cavity, releasing the extrusion and fixation of the casting. The casting can fall out of the mold cavity under the action of gravity without the need for staff to manually take out the casting, which is relatively convenient to use.

[0018] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the utility model.

[0030] Please refer to Figures 1 - 6 As shown, the present utility model is an automatic high-density die-casting forming machine for aluminum alloy die-castings, including a rotary table 1. A mold cavity 2 is provided on the outer surface of the rotary table 1. A blanking assembly 3 is arranged inside the rotary table 1. A driving assembly 4 and a support assembly 6 are arranged at the bottom of the rotary table 1. A pressing-down assembly 5 is arranged on the top of the rotary table 1. The blanking assembly 3 is used to help the casting to be removed from the mold cavity 2. The driving assembly 4 is used to drive the rotary table 1 to rotate. The pressing-down assembly 5 is used to cooperate with the mold cavity 2 for die-casting.

[0031] Start the pressing-down assembly 5. The pressing-down assembly 5 enters the mold cavity 2 on the rotary table 1. Then, the molten aluminum is injected between the pressing-down assembly 5 and the mold cavity 2, so that the molten aluminum is die-cast into shape under the action of the pressing-down assembly 5. Subsequently, the pressing-down assembly 5 moves upward to separate from the mold cavity 2. Start the driving assembly 4 to drive the rotary table 1 and the mold cavity 2 to rotate. At this time, the mold cavity 2 with the casting inside moves away from directly below the pressing-down assembly 5, and another group of idle mold cavities 2 moves to directly below the pressing-down assembly 5. During the rotation, the blanking assembly 3 on the mold cavity 2 with the casting inside moves, and the blanking assembly 3 separates from the casting formed in the mold cavity 2. At this time, the casting can be removed from the mold cavity 2 and fall below the support assembly 6.

[0032] Through the connection between the blanking component 3 and the driving component 4 of the present utility model, the driving component 4 drives the rotating table 1 and the mold cavity 2 to rotate. During the rotation process, the blanking component 3 automatically retracts, so that the blanking component 3 is separated from the casting in the mold cavity 2. At this time, the casting is no longer subjected to the extrusion and fixation of the blanking component 3, and the casting can fall out of the mold cavity 2 under the action of gravity and fall below the supporting component 6, thereby realizing automatic demolding without manual removal of the casting by the staff, which is relatively convenient to use.

[0033] In one embodiment, for the above-mentioned blanking component 3, the blanking component 3 includes a sliding rod 301. One end of the sliding rod 301 is fixedly connected with a limiting plate 302, and the other end of the sliding rod 301 is fixedly connected with a sliding plate 303. The bottom of the sliding plate 303 is fixedly connected with a round rod 304. An arc-shaped groove 305 is formed on the surface of the supporting component 6, and the round rod 304 is slidably connected inside the arc-shaped groove 305. A spring 306 is fixedly connected to the outer surface of the limiting plate 302, and the spring 306 is fixedly connected inside the rotating table 1. Both the sliding rod 301 and the limiting plate 302 are slidably connected with the rotating table 1, and the sliding plate 303 is slidably connected with the mold cavity 2.

[0034] The rotating table 1 drives the sliding plate 303 to rotate, and the round rod 304 at the bottom of the sliding plate 303 moves along the arc-shaped groove 305. During the movement, the round rod 304 is separated from the arc-shaped groove 305. At this time, the spring 306 pulls the sliding plate 303 and the round rod 304 to move through the sliding rod 301, so that the sliding plate 303 slides in the mold cavity 2, and the sliding plate 303 moves away from the casting in the mold cavity 2, thereby releasing the extrusion and fixation of the casting. Subsequently, the rotating table 1 continues to drive the sliding plate 303 to rotate, and the round rod 304 at the bottom of the sliding plate 303 enters the arc-shaped groove 305 again. During the movement along the arc-shaped groove 305, the round rod 304 drives the sliding plate 303 to move, the sliding plate 303 drives the sliding rod 301 and the limiting plate 302 to move, and the limiting plate 302 stretches the spring 306. The limiting plate 302 can limit the moving distance of the sliding rod 301 to prevent the sliding rod 301 from slipping out of the rotating table 1.

[0035] In one embodiment, for the above-mentioned driving component 4, the driving component 4 includes a support 401. The support 401 is fixedly connected to the bottom of the supporting component 6. A motor 402 is fixedly connected to the outer surface of the support 401. A first gear 403 is rotatably connected to the output shaft of the motor 402. A second gear 404 is meshed with the outer surface of the first gear 403. A rotating shaft 405 is fixedly connected to the outer surface of the second gear 404, and the rotating shaft 405 is fixedly connected with the rotating table 1. Both the first gear 403 and the second gear 404 are rotatably connected inside the supporting component 6.

[0036] Start the motor 402. The motor 402 drives the first gear 403 to rotate. The first gear 403 meshes with the second gear 404 and drives the second gear 404 to rotate. The second gear 404 drives the rotating shaft 405 to rotate, and the rotating shaft 405 drives the rotating table 1 to rotate.

[0037] In one embodiment, for the above-mentioned pressing component 5, the pressing component 5 includes an electric push rod 501. The movable end of the electric push rod 501 is fixedly connected with a pressing plate 502. The bottom of the pressing plate 502 is fixedly connected with a pressing die 503. An injection hole 504 is formed in the top of the pressing plate 502. The pressing die 503 is used to cooperate with the mold cavity 2.

[0038] Start the electric push rod 501. The electric push rod 501 pushes the pressing plate 502 and the pressing die 503 to descend, so that the pressing die 503 enters the inside of the mold cavity 2. Then, pour the molten aluminum through the injection hole 504 between the pressing die 503 and the mold cavity 2 to carry out die casting.

[0039] In one embodiment, for the above-mentioned supporting component 6, the supporting component 6 includes a square table 601. The top of the square table 601 is fixedly connected with a bracket 602. The top of the bracket 602 is fixedly connected with a top plate 603. The fixed end of the electric push rod 501 is fixedly connected with the top plate 603. The bottom of the square table 601 is fixedly connected with support legs 604. The support 401 is fixedly connected to the bottom of the square table 601. Both the first gear 403 and the second gear 404 are rotatably connected inside the square table 601. A blanking port 605 is formed on the outer surface of the square table 601.

[0040] The support legs 604 support the square table 601, so that the support 401 and the bracket 602 on the square table 601 are kept stable. The top plate 603 on the bracket 602 is located at the position for installing and fixing the electric push rod 501, so that the electric push rod 501 can work stably. The arc-shaped groove 305 is disconnected at the blanking port 605 on the square table 601. When the round rod 304 moves along the arc-shaped groove 305 to the blanking port 605, the spring 306 can pull the sliding plate 303 and the round rod 304 to slide, so that the sliding plate 303 moves away from the casting in the mold cavity 2, and the casting can fall from the blanking port 605.

[0041] In one embodiment, for the above-mentioned square table 601, a box body 7 is arranged at the bottom of the square table 601, and a coolant is arranged inside the box body 7.

[0042] In one embodiment, for the above-mentioned support legs 604, a round plate 8 is fixedly connected to the end of the support legs 604.

[0043] The casting falls into the box body 7 through the blanking port 605 on the square platform 601, and the casting is cooled by the coolant in the box body 7. The round plate 8 can increase the grounding area of the supporting legs 604, making the support of the supporting legs 604 on the square platform 601 more stable.

[0044] In summary, by means of the above technical solution of the present utility model, by starting the electric push rod 501, the electric push rod 501 pushes the pressing plate 502 and the pressing die 503 to descend, so that the pressing die 503 enters the inside of the die cavity 2, and then the molten aluminum is injected between the pressing die 503 and the die cavity 2 through the injection hole 504 to carry out die casting. After die casting is completed, the electric push rod 501 drives the pressing die 503 to move upward and separate from the rotating table 1. Start the motor 402, the motor 402 drives the first gear 403 to rotate, the first gear 403 meshes with the second gear 404 and drives the second gear 404 to rotate, the second gear 404 drives the rotating shaft 405 to rotate, the rotating shaft 405 drives the rotating table 1 to rotate, the rotating table 1 drives the sliding plate 303 to rotate, and the round rod 304 at the bottom of the sliding plate 303 moves along the arc-shaped groove 305. When the round rod 304 moves to the blanking port 605, the round rod 304 separates from the arc-shaped groove 305. At this time, the spring 306 pulls the sliding plate 303 and the round rod 304 to move through the sliding rod 301, so that the sliding plate 303 slides in the die cavity 2, and the sliding plate 303 moves away from the casting in the die cavity 2, thereby releasing the extrusion fixation on the casting. The casting can fall from the die cavity 2 and the blanking port 605 into the box body 7. Subsequently, the rotating table 1 continues to drive the sliding plate 303 to rotate, and the round rod 304 at the bottom of the sliding plate 303 enters the arc-shaped groove 305 again. During the process of moving along the arc-shaped groove 305, the round rod 304 drives the sliding plate 303 to move for resetting.

[0045] Through the above technical solution, 1. Through the connection between the blanking component 3 and the driving component 4, the driving component 4 drives the rotating table 1 and the die cavity 2 to rotate. During the rotation process, the blanking component 3 automatically retracts, so that the blanking component 3 separates from the casting in the die cavity 2. At this time, the casting is no longer subjected to the extrusion fixation of the blanking component 3, and the casting can be disengaged from the die cavity 2 under the action of gravity and fall below the supporting component 6, thereby realizing automatic demoulding without the need for staff to manually take out the casting, which is more convenient to use. 2. Through the connection between the sliding plate 303 and the rotating shaft 405, the rotating shaft 405 drives the rotating table 1 and the die cavity 2 to rotate. During the rotation of the rotating table 1, the round rod 304 at the bottom of the sliding plate 303 will move along the arc-shaped groove 305. When the round rod 304 moves to the blanking port 605, the round rod 304 separates from the arc-shaped groove 305, and the arc-shaped groove 305 no longer restricts the round rod 304. At this time, the spring 306 can pull the sliding plate 303 and the round rod 304 to move, so that the sliding plate 303 moves away from the casting in the die cavity 2, releasing the extrusion fixation on the casting.
