Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot processing technology, specifically to an aluminum ingot casting mold demolding device. Background Technology

[0002] Demolding is a crucial step in the aluminum ingot casting process. Traditional aluminum ingot demolding often uses a chain conveyor belt in conjunction with a mold. The mold rotates with the conveyor belt, and the molten aluminum cools and solidifies within the mold cavity. However, due to the adhesion between the cooled aluminum ingot and the inner wall of the mold cavity, gravity alone is insufficient to ensure the ingot can be smoothly removed from the mold.

[0003] To address this issue, a common practice in the past was to add an additional striking mechanism, such as using a hydraulic rod to retract and drive an iron cone to strike the aluminum ingot, causing it to vibrate and demold. However, this method has many drawbacks. On the one hand, frequent and forceful striking of aluminum ingots that are not fully cooled, have unstable internal structures, and low strength can easily cause deformation at the stress points, reducing the yield of aluminum ingot production. On the other hand, the additional striking mechanism not only requires specialized design, manufacturing, and installation costs, but also occupies more production space, increasing the overall size of the equipment and hindering the compact layout of the production line. This is especially true for small and medium-sized foundries with limited space, further restricting production flexibility.

[0004] Therefore, this application provides a demolding device for aluminum ingot casting molds. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum ingot casting mold demolding device to solve the problem mentioned in the background art that frequent hammering of aluminum ingots causes deformation of aluminum ingots at the stress point, reducing the yield of aluminum ingot production and increasing equipment costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum ingot casting mold demolding device, comprising: Chain conveyor; Aluminum ingot casting molds, multiple aluminum ingot casting molds are evenly fixed on a chain conveyor by bolts. The upper surface of the aluminum ingot casting mold is provided with a forming cavity, and the lower end of the forming cavity is provided with an installation cavity. A gear is elastically rotatably connected to the center of the installation cavity through a torsion spring. A rack is slidably connected to one side of the installation cavity. The rack meshes with the gear. One end of the rack extends to the outer wall of the aluminum ingot casting mold and is welded with a counterweight.

[0007] By adopting the above technical solution, a forming cavity is set up for the forming of aluminum ingots. After the aluminum ingots cool, the chain conveyor drives the aluminum ingot mold to rotate in a cycle. When the aluminum ingot mold moves to a position perpendicular to the ground, the counterweight on one side of the aluminum ingot mold slides down under the influence of gravity. During this process, the counterweight pulls the rack and moves downwards at the same time. As the rack moves, it drives the gear to rotate. When the gear rotates, the torsion spring installed on its outer side deforms and generates elastic potential energy. When the aluminum ingot mold moves to an inverted position, the counterweight no longer exerts a pulling force on the rack. The elastic potential energy is released through the torsion spring to drive the gear to rotate and reset. During this process, the gear pulls the rack to reset quickly, so that the counterweight at the end of the rack collides with the outer wall of the aluminum ingot mold. The vibration generated during the collision causes the aluminum ingot to be demolded. No additional hammering mechanism is required, and the counterweight does not come into contact with the aluminum ingot during the demolding process, thus improving the yield of aluminum ingots.

[0008] Preferably, the chain conveyor further includes a mounting frame, on both sides of which rollers are rotatably connected, and chains are provided on both sides between the two rollers. Multiple aluminum ingot casting molds are evenly installed between the two chains by bolts.

[0009] Using the above technical solution, the mounting frame provides the mounting base for the demolding device. The rotation of the roller shaft drives the chain to rotate, which in turn drives the aluminum ingot mold mounted on the outer wall of the chain to rotate cyclically.

[0010] Preferably, a guide rod is provided on the side of the mounting cavity near the rack, and a limiting groove is welded on the side of the rack away from the gear, the limiting groove being slidably connected to the inside of the guide rod.

[0011] By adopting the above technical solution, the setting of the limiting slide groove and guide rod ensures that the rack always moves in a straight line, and limits the maximum stroke of the rack to prevent it from moving out of the mounting cavity.

[0012] Preferably, a rubber pad is fixedly installed on the side of the counterweight near the outer wall of the molding cavity.

[0013] By adopting the above technical solution, the installation of rubber pads can ensure that the counterweight will not damage the aluminum ingot mold when it collides with the mold.

[0014] Preferably, racks are slidably connected to both sides of the mounting cavity, and the two racks mesh with the two sides of the gear respectively. One end of each rack extends to the outer wall of the aluminum ingot mold on both sides, and counterweights are welded to the extension.

[0015] Using the above technical solution, when it is necessary to demold pure aluminum ingots or aluminum ingots with low iron content that are prone to sticking to the mold, when the aluminum ingot mold is moved to a position perpendicular to the ground, the counterweight on one side of the aluminum ingot mold slides down under the influence of gravity. During this process, the counterweight pulls the rack and moves it downwards at the same time. As the rack moves, it drives the gear to rotate. When the gear rotates, it drives the rack on the other side to move upwards, thereby causing the two counterweights to open outwards respectively. When the aluminum ingot mold moves to an inverted position, the two counterweights simultaneously reset and impact the outer walls on both sides of the aluminum ingot mold, improving the vibration effect and preventing demolding failure.

[0016] Preferably, magnets two are fixedly installed on the outer walls of both counterweights, and a mounting plate is welded to the lower right end of the mounting frame. Magnet one is fixedly installed on the upper surface of the mounting plate, and the magnetic poles of magnet one and magnet two are opposite.

[0017] Using the above technical solution, during the process of the two counterweights opening outwards simultaneously, the gear needs to overcome the gravity of the counterweight located at the upper end of the aluminum ingot mold. At this time, the installed magnets one and two provide this power. After the aluminum ingot mold moves to the inverted state and completes one impact, the counterweight on the side closer to magnet one is affected by the magnetic force and opens up again. When the distance between the counterweight and magnet one increases, causing the magnetic force to be less than the elastic potential energy of the torsion spring, the counterweight will impact the aluminum ingot mold again, thereby achieving multiple vibrations and improving the demolding effect.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the proportion calibration mixer for wine blending: 1. The device achieves demolding by generating vibration through the impact of a counterweight against the outer wall of the mold, without direct contact with the aluminum ingot throughout the process. This fundamentally solves the problem of deformation caused by direct impact on the aluminum ingot in traditional hammering mechanisms. At the same time, the polishing treatment of the inner wall of the forming cavity reduces the adhesion between the aluminum ingot and the cavity wall. Combined with vibration, it precisely destroys the residual adhesion, ensuring that the aluminum ingot is completely detached under the dual action of gravity and vibration. This effectively avoids deformation of incompletely cooled and low-strength aluminum ingots due to concentrated stress points, significantly improving the yield rate of aluminum ingot production.

[0019] 2. The device utilizes the principle of "gravity-elastic potential energy conversion," achieving vibration demolding through the synergy of counterweights, gear racks, and torsion springs, eliminating the need for additional hydraulic rods, iron cones, or other striking mechanisms. This not only saves on the design, manufacturing, and installation costs of striking mechanisms but also avoids additional components occupying production space, resulting in a more compact overall structure that is better suited to the site limitations of small and medium-sized foundries. This enhances the flexibility of production line layout and reduces equipment investment and site planning costs for enterprises. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Example 1: Please see Figure 1-3 This utility model provides a technical solution: an aluminum ingot casting mold demolding device, comprising: The chain conveyor 10 serves as the conveying foundation of the entire device. Its mounting frame 11 is made of rigid material to provide stable support for each component. Rollers 12 are rotatably connected to the left and right sides of the mounting frame 11 through bearings. The rollers 12 are driven by a motor. Chains 13 are respectively fitted on both sides between the two rollers 12 to ensure the synchronization of power transmission. Multiple aluminum ingot molds 20 are evenly and firmly installed between the two chains 13 by bolts, so that the aluminum ingot molds 20 can be continuously conveyed with the cyclic movement of the chains 13, thus establishing a continuous operation path for the aluminum liquid cooling and molding and demolding processes. The upper surface of the aluminum ingot casting mold 20 is provided with a forming cavity 21. The shape of the cavity is adapted to the shape of the aluminum ingot to be produced. It is used to receive the molten aluminum and cool it to form a solid shape. The molten aluminum is poured into the forming cavity 21 of the aluminum ingot casting mold 20. The molten aluminum cools naturally in the forming cavity 21 and gradually solidifies to form an aluminum ingot. The lower end of the forming cavity 21 has a reserved mounting cavity 22 to provide installation space for the transmission components. The center of the mounting cavity 22 is connected to the gear 23 by a torsion spring. The torsion spring ensures that the gear 23 can rotate flexibly and can quickly return to its original position after being subjected to force. A rack 24 is slidably connected to one side of the mounting cavity 22. The rack 24 and the gear 23 mesh with each other to form a complete transmission structure. One end of the rack 24 extends to the outer wall of the aluminum ingot mold 20 and is welded with a counterweight 25. The counterweight 25 provides the power basis for the subsequent impact action. To ensure the stability of the rack 24's movement, a guide rod 27 is fixedly provided on the side of the mounting cavity 22 near the rack 24. A limiting groove 26 is welded on the side of the rack 24 away from the gear 23. The limiting groove 26 is slidably sleeved inside the guide rod 27 to form a guiding and limiting structure to prevent the rack 24 from deviating or falling out. Meanwhile, a rubber pad is fixedly installed on the side of the counterweight 25 near the outer wall of the aluminum ingot mold 20. The rubber pad is soft and can buffer the impact and protect the mold from damage.

[0024] Working principle: Before the operation begins, molten aluminum is poured into the forming cavity 21 of the aluminum ingot mold 20. The aluminum cools naturally in the forming cavity 21 and gradually solidifies to form an aluminum ingot. After the aluminum ingot has completely cooled and solidified, the chain conveyor 10 is started, and the roller 12 begins to rotate, driving the chains 13 on both sides to circulate. The aluminum ingot mold 20 installed on the chains 13 moves synchronously and enters the demolding process. When the aluminum ingot mold 20 moves with the chains 13 to a position perpendicular to the ground, the counterweight 25 on one side of the aluminum ingot mold 20 slides away from the aluminum ingot mold 20 under its own weight. During this process, the counterweight 25 synchronously pulls the rack 24 welded to it to move downward along the guide rod 27. Since the rack 24 and the gear 23 mesh with each other, the movement of the rack 24 drives the gear 23 to rotate. The torsion spring connected to the outside of the gear 23 is deformed by the torsional force and stores elastic potential energy. As the chain 13 continues to move, the aluminum ingot mold 20 continues to rotate until it moves to an inverted state. At this point, the counterweight 25 is no longer subjected to the downward pull of gravity, and the torsion spring begins to release the elastic potential energy stored previously, driving the gear 23 to rotate in the opposite direction to reset. The reset of the gear 23 drives the rack 24 to move rapidly upward along the guide rod 27. The rack 24 then pulls the counterweight 25 to quickly approach the aluminum ingot mold 20 and collide with the outer wall of the aluminum ingot mold 20. The vibration generated by the impact is transmitted through the aluminum ingot mold 20 to the aluminum ingot in the forming cavity 21, which breaks the adhesion between the aluminum ingot and the inner wall of the forming cavity 21. Under the dual action of gravity and vibration, the aluminum ingot falls out of the forming cavity 21, completing the demolding. The entire demolding process does not require the addition of an additional striking mechanism, and the counterweight 25 never directly contacts the aluminum ingot, effectively avoiding deformation of the aluminum ingot due to impact, and significantly improving the yield of aluminum ingot production.

[0025] Example 2: like Figure 4-5 As shown, in order to enable the equipment to demold pure aluminum ingots or aluminum ingots with low iron content that are prone to sticking to the mold, the structure of the chain conveyor 10 is consistent with that of Embodiment 1. The core optimization point is the internal structure of the mounting cavity 22 of the aluminum ingot mold 20. Racks 24 are slidably connected to both sides of the mounting cavity 22. Two racks 24 are symmetrically arranged on both sides of the gear 23 and mesh with the gear 23 to form a bidirectional transmission structure. One end of each rack 24 extends to the outer walls of both sides of the aluminum ingot mold 20, and counterweights 25 are welded to the extended portions, so that the aluminum ingot mold 20... Both sides of the mounting cavity 22 are equipped with impact power sources, which can generate bidirectional vibration. At the same time, guide rods 27 and limiting grooves 26 are provided on both sides of the mounting cavity 22 corresponding to the rack 24, ensuring that both racks 24 can move in a stable linear motion. In order to assist the counterweight 25 to open and achieve multiple impacts, magnets 28 are fixedly installed on the outer walls of the two counterweights 25. Meanwhile, a mounting plate 14 is welded to the lower right side of the mounting frame 11. Magnets 15 are fixedly installed on the upper surface of the mounting plate 14. Magnets 15 and 28 have opposite magnetic poles and can generate a magnetic force that attracts each other, providing auxiliary power for the movement of the counterweights 25. When the aluminum ingot mold 20 moves to a position perpendicular to the ground, the counterweight 25 near the bottom slides down under its own weight, pulling the corresponding rack 24 to move downward along the guide structure. Since the rack 24 meshes with the gear 23, its movement drives the gear 23 to rotate. The gear 23 synchronously drives the rack 24 on the other side to move upward, thereby causing the counterweight 25 at the end of the rack 24 to open upward. Ultimately, the two counterweights 25 open outward to both sides of the aluminum ingot mold 20. During this process, the counterweight 25 located at the upper end of the aluminum ingot mold 20 is hindered by its own weight. At this time, the magnet 15 on the mounting plate 14 and the magnet 28 on the counterweight 25 generate an attraction force, providing auxiliary power for the rotation of the gear 23 and helping the counterweight 25 to open smoothly. Simultaneously, the torsion spring further stores elastic potential energy. As the chain 13 continues to move, the aluminum ingot mold 20 flips to an inverted state. At this time, the gravitational pull on the two counterweights 25 disappears, the torsion spring releases its elastic potential energy, and drives... The moving gear 23 quickly resets, which in turn drives the two racks 24 to reset synchronously. The two counterweights 25 impact the outer walls of the aluminum ingot mold 20 on both sides, generating bidirectional vibration. The vibration intensity is significantly improved, effectively breaking the adhesion between the easily sticking aluminum ingot and the inner wall of the forming cavity 21, avoiding demolding failure. After the first impact, the aluminum ingot mold 20 continues to move with the chain 13. The counterweight 25 near the magnet 15 opens outward again under the attraction of the magnet 15 and the magnet 28. As the aluminum ingot mold 20 continues to move, the distance between the counterweight 25 and the magnet 15 gradually increases, and the magnetic force between them weakens. When the magnetic force is less than the elastic potential energy of the torsion spring, the torsion spring drives the gear 23 to reset again, causing the counterweight 25 to impact the outer wall of the aluminum ingot mold 20 again, achieving multiple vibrations. The design of multiple vibrations further enhances the demolding effect, ensuring that the easily sticking aluminum ingot can be smoothly removed from the forming cavity 21, ensuring the continuity of production.
