Technical Field
[0001] This utility model belongs to the field of die casting processing technology, specifically an air-jet chip removal device for aluminum alloy die castings. Background Technology
[0002] In modern industrial production, aluminum alloy die castings are widely used in many fields such as automobile manufacturing, aerospace, and electronic equipment due to their advantages such as light weight, high strength, and good corrosion resistance. However, during the die casting process, various aluminum chips, impurities, and oxides inevitably remain on the surface of aluminum alloy die castings. These residues not only affect the appearance quality of the die castings but may also have serious negative impacts on their subsequent processing, assembly, and performance.
[0003] Meanwhile, the patent specification with application number CN112570681B discloses an automatic cleaning mechanism for the inside of a die-casting mold. "At least two first jet nozzles are arranged at the center of the mounting groove of the die-casting mold forming moving mold template, and at least four second jet nozzles are symmetrically arranged on both sides of the mounting groove. The first and second jet nozzles are connected to an external high-pressure gas supply device through a vent pipe. After the die-casting mold is opened and the product is removed from the cavity, a high-pressure gas medium is supplied to the die-casting mold through the high-pressure gas supply device. The high-pressure gas medium is then sprayed at a fixed point and at a high frequency onto the forming surface of the product forming moving mold body inside the die-casting mold forming moving mold template through the first and second jet nozzles, promptly removing residual metal dust and slag from the mold."
[0004] Existing chip removal devices for aluminum alloy die castings are often difficult to adapt flexibly to die castings of different sizes and shapes during use. Typically, the chip removal components of the device are in fixed positions and cannot be adjusted to suit the complex shape of the die casting, resulting in poor chip removal performance and serious aluminum chip residue problems. Secondly, the existing fixing methods for die castings are too simple and crude, lacking protective measures for the die casting surface. This can easily cause scratches, wear, and other damage to the die casting surface during the fixing process, affecting the appearance quality and performance of the product.
[0005] Therefore, an air jet chip removal device for aluminum alloy die castings is proposed to address the above problems. Utility Model Content
[0006] To address the problems mentioned in the background art, this utility model provides an air jet chip removal device for aluminum alloy die castings, which has the advantages of fine cleaning of aluminum chips, significantly improving chip removal efficiency and quality, fully protecting the surface quality of die castings, and improving product quality.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an air jet chip removal device for aluminum alloy die castings, comprising a worktable, an electric slide rail and a support frame mounted on the top of the worktable, a fixing plate mounted on the outer surface of the electric slide rail, a fixing component mounted on the top of the fixing plate, an air jet assembly mounted on the lower inner wall of the support frame, the air jet assembly including an electric telescopic rod fixedly connected to the upper inner wall of the support frame, a lifting plate fixedly connected to the output end of the electric telescopic rod, an air knife mounted on one side of the bottom end of the lifting plate, a plurality of adjusting rods slidably connected to the inner surface of the lifting plate, a spring wound around the outer surface of each of the adjusting rods, a connecting plate fixedly sleeved on the outer surface of each of the adjusting rods, the bottom ends of each of the springs fixedly connected to the connecting plates, an air nozzle fixedly connected to the inner surface of each of the adjusting rods, and a ball bearing mounted at the bottom end of each of the air nozzles.

[0026] 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.
[0027] like Figures 1 to 5As shown, this utility model provides an air jet chip removal device for aluminum alloy die castings, including a worktable 1. An electric slide rail 9 and a support frame 8 are installed on the top of the worktable 1. A fixing plate 2 is installed on the outer surface of the electric slide rail 9. A fixing component 3 is provided on the top of the fixing plate 2. An air jet component 5 is installed on the lower inner wall of the support frame 8. By setting the electric slide rail 9 and the support frame 8 on the top of the worktable 1, installing the fixing plate 2 and the fixing component 3 on the electric slide rail 9, and installing the air jet component 5 on the lower inner wall of the support frame 8, an integrated design for fixing and chip removal of aluminum alloy die castings is realized, which is convenient to operate, saves space, and improves work efficiency.
[0028] The jet assembly 5 includes an electrically operated telescopic rod 7 fixedly connected to the inner wall of the support frame 8. A lifting plate 54 is fixedly connected to the output end of the electrically operated telescopic rod 7. An air knife 52 is installed on one side of the bottom end of the lifting plate 54. Several adjusting rods 53 are slidably connected to the inner surface of the lifting plate 54. Springs 531 are wound around the outer surfaces of each adjusting rod 53. Connecting plates 532 are fixedly sleeved on the outer surfaces of each adjusting rod 53. The bottom ends of each spring 531 are fixedly connected to the connecting plates 532. Air nozzles 533 are fixedly connected to the inner surface of each part, and ball bearings 534 are installed at the bottom of each air nozzle 533. Under the action of the electric telescopic rod 7 driving the lifting plate 54, the height of the air knife 52 and the air nozzles 533 can be flexibly adjusted according to the height and surface contour of the aluminum alloy die casting. The air knife 52 can efficiently blow away aluminum chips over a large area, while the air nozzles 533 can fit against the complex surface of the die casting with the assistance of the ball bearings 534, especially in small gaps and hard-to-reach areas, to perform fine cleaning of aluminum chips, significantly improving chip removal efficiency and quality.
[0029] Specifically, the air knife 52 and several air nozzles 533 are all fixedly connected to transmission pipes 6. The transmission pipes 6 are all flexible hoses, and the transmission pipes 6 are all used to connect to an air compressor. This makes the air knife 52 and air nozzles 533 more flexible in position adjustment, better adapting to the chip removal needs of aluminum alloy die castings of different shapes, and ensuring chip removal effect.
[0030] like Figures 1 to 5 As shown, two slide rods 51 are fixedly connected to both ends of the lifting plate 54. The inner walls on both sides of the support frame 8 are provided with slide grooves 4 that cooperate with the slide rods 51, which ensures the stability of the lifting plate 54 during the up and down movement, so that the air knife 52 and the air nozzle 533 can smoothly approach or move away from the aluminum alloy die casting and accurately perform chip removal work.
[0031] Furthermore, the fixing component 3 includes four long slots 35 formed at the top of the fixing plate 2. Each of the four long slots 35 has a long rod 34 fixedly connected to its inner surface. Each of the four long rods 34 has a fixing block 32 slidably sleeved on its outer surface. Each of the four long rods 34 has a spring 36 wound around its outer surface. One end of each of the four springs 36 is fixedly connected to one end of each of the four long rods 34, and the other end of each of the four springs 36 is fixedly connected to one side of the inner wall of each of the four long slots 35. Depending on the size of the aluminum alloy die-casting part, the elastic force of the springs 36 can push the fixing block 32 to slide on the long rod 34, thereby achieving flexible fixing of die-casting parts of different sizes and enhancing the versatility of the device.
[0032] like Figures 1 to 5 As shown, two guide blocks 331 are fixed at both ends of the four fixed blocks 32, and guide grooves 33 that cooperate with the two guide blocks 331 are opened on the inner surface of the four long grooves 35. This further ensures the stability of the fixed blocks 32 during the sliding process, prevents the fixed blocks 32 from shifting, and thus more firmly fixes the aluminum alloy die casting, preventing the die casting from shaking during the chip removal process and affecting the chip removal effect.
[0033] It is worth noting that each of the four fixing blocks 32 is fixedly connected to a soft pad 31 at one end, which can effectively prevent the fixing blocks 32 from causing scratches, wear and other damage to the surface of the die casting, thus protecting the surface quality of the die casting and improving product quality.
[0034] Working principle and process: First, the aluminum alloy die-cast part is placed on the fixing component 3 at the top of the fixing plate 2. According to the size of the die-cast part, the fixing block 32 slides along the long rod 34 under the action of the spring 36. Through the guiding action of the guide blocks 331 at both ends in the guide groove 33, the die-cast part is steadily fixed. The soft pad 31 is used to protect the surface of the die-cast part. Then, the electric telescopic rod 7 is activated. The electric telescopic rod 7 pushes the lifting plate 54 to move up and down along the mating direction of the slide rod 51 and the slide groove 4, which drives the air knife 52 and the air nozzle 533 to approach the aluminum alloy die-cast part. The compressor delivers high-pressure gas to the air knife 52 and the air nozzle 533 through the transmission pipe 6. The air knife 52 sprays high-pressure airflow to remove chips over a large area on the surface of the die casting. The ball bearing 534 at the bottom of the air nozzle 533 can roll on the surface of the die casting. The adjusting rod 53 can flexibly adjust the position of the air nozzle 533 under the action of the spring 531, so that the air nozzle 533 can adapt to the complex shape of the die casting surface and perform fine chip removal on tiny gaps and hard-to-reach areas. At the same time, the electric slide rail 9 can drive the fixed plate 2 and the die casting to move, and cooperate with the air knife 52 and the air nozzle 533 in all directions to complete the chip removal work.
