Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum alloy casting processing, more specifically, the present application relates to a rapid cooling device for aluminum alloy casting processing and a cooling method thereof. BACKGROUND

[0002] Aluminum alloy castings refer to various parts or products cast with aluminum alloy as the material. Aluminum alloy has many advantages such as small density, high strength, good corrosion resistance, etc., and is widely used in many fields such as aerospace, automobile manufacturing, and mechanical processing. Aluminum alloy castings can be made into parts with complex shape and accurate size through specific casting process, meeting the diversified needs of different industries for the performance and structure of parts. In the casting process, a reasonable cooling method plays a crucial role in ensuring the quality and performance of aluminum alloy castings. The present application relates to a rapid cooling device for aluminum alloy casting processing, which is optimized and designed for this key link.

[0003] According to the patent document CN120001969A, a magnesium-aluminum alloy casting forming cooling device is disclosed, which relates to the technical field of casting process equipment. It includes a cooling pool, an installation rack fixed on the top of the cooling pool, a chain conveyor belt arranged on one side of the installation rack, a plurality of clamping mechanisms arranged at the bottom of the chain conveyor belt, a cold air mechanism arranged on the cooling pool, a water circulation rack arranged on the side of the cooling pool top away from the cold air mechanism, and a placing rack arranged on the top of the cooling pool. When the limiting block slides into the end of the inner wall of the back-shaped limiting frame, the second bevel gear meshes with the first bevel gear, and the third bevel gear meshes with the fourth bevel gear. The activated chain conveyor belt drives the filtering assembly to move along the threaded rod to the low filter plate side, causing the entire filtering assembly to move to the other side of the cooling pool. This reduces the difficulty of cleaning metal debris in the cooling pool and allows water impurities in the cooling pool to be concentrated in the filtering assembly, reducing power output during the collection of impurities.

[0004] During the cooling process after the heating process of aluminum alloy castings, it is usually necessary to ensure that the aluminum alloy can quickly immerse in the cooling liquid. However, if the aluminum alloy casting is directly sent to the water pool after completing the heating process, a large amount of mist will be generated when the cooling water contacts the casting. This mist not only reduces the visibility of the working environment and affects the operator's vision, but also may cause certain harm to the respiratory system. In addition, if the cooling speed is too fast or too rapid, a large internal stress may be generated inside the aluminum alloy casting, leading to quality problems such as cracks and deformation of the casting, and thus affecting the overall performance and service life of the casting. SUMMARY

[0005] In order to overcome the above-mentioned defects of the prior art, the present application provides a rapid cooling device for aluminum alloy casting processing and a cooling method thereof, and the technical problems to be solved by the present application are: after the aluminum alloy casting is just completed after the heating process, if it is directly sent into the pool, a large amount of mist will be generated when the cooling water contacts the casting, which not only reduces the visibility of the working environment and affects the line of sight of the operator, but also may cause certain harm to the respiratory system, in addition, if the cooling speed is too fast and too rapid, a large internal stress may be generated in the aluminum alloy casting, resulting in quality problems such as cracks and deformation of the casting, and further affecting the overall performance and service life of the casting.

connected with side vertical plates 123, the top of the two side vertical plates 123 is fixedly connected with a top plate 124, the top front side of the water tank placing plate 122 is fixedly

fixedly connected with the rear middle of the water outlet tank 125, the bottom of the left and right sides of the water outlet tank 125 is fixedly connected with a pipeline 126, one end of the two pipelines 126 away from the water outlet tank 125 is fixedly connected with a top cover frame 128, the left and right sides of the bottom of the top cover frame 128 is fixedly connected on the top of the two vertical Z-shaped rotating blocks 11110, the front side of the left and right sides of the bottom of the top cover frame 128 is fixedly connected with a top cover frame positioning block 129,

the water pump tank 1210 is fixedly connected on the left and right sides of the top of the top cover frame 128.

[0040] After the hot working process of the aluminum alloy casting is completed, the staff places the aluminum alloy casting in the middle of the inner side of the metal casting placing mechanism 2 through a special transfer tool, and then starts the motor 11114. After the motor 11114 is started, the output end drives the third transmission disc 11115 to rotate, the third transmission disc 11115 drives the fourth transmission disc 11117 to rotate through the second track 11116, the fourth transmission disc 11117 is fixed on the rear side columnar rotating rod 115, and then the rear side columnar rotating rod 115 rotates. When the rear side columnar rotating rod 115 rotates, the circular turntable 11111 on the outer wall of the two sides rotates, the pull rod 11112 on the circular turntable 11111 pulls the front U-shaped rotating vertical plate 1117 to swing backward. Since the top of the left and right two groups of U-shaped rotating vertical plates 1117 is rotatably connected with the bidirectional hinged side rod 1118, when the front two U-shaped rotating vertical plates 1117 swing to the rear side, the rear two U-shaped rotating vertical plates 1117 are driven to swing to the rear side synchronously. The top of the front two U-shaped rotating vertical plates 1117 is rotatably connected with the vertical Z-shaped rotating block 11110 through the rotating rod 1119, and the inner wall of the vertical Z-shaped rotating block 11110 is rotatably connected with the left and right sides of the outer wall of the columnar cross rod 1115. Therefore, when the U-shaped rotating vertical plate 1117 swings, the vertical Z-shaped rotating block 11110 is driven to flip to the front side and drives the columnar cross rod 1115 to move downward. The columnar cross rod 1115 is fixed on the inner side of the middle part of the two sliding side plates 1113, the sliding side plates 1113 slide on the columnar guide vertical rod 1112 in the inner wall of the rectangular side frame 1111, and the bottom is connected with the inner wall bottom of the rectangular side frame 1111 through the spring 1114. Therefore, the stability of the up-down movement of the sliding side plate 1113 can be ensured. When the columnar cross rod 1115 moves downward and the two vertical Z-shaped rotating blocks 11110 flip to the front side, the top cover frame 128 is driven to move downward and rotate with the two vertical Z-shaped rotating blocks 11110. At the same time, when the rear side columnar rotating rod 115 rotates, the transmission disc 118 at the outer end is driven to rotate through the track 119, thereby driving the second transmission disc 1110 to rotate, so that the middle part of the inner side of the metal casting placing mechanism 2 rotates upward with the track 119, and the middle part of the inner side of the metal casting placing mechanism 2 is closed with the top cover frame 128, covering the aluminum alloy casting placed on the metal casting placing mechanism 2. At this time, the water tank 1210 sends a small amount of cooling water to the inside of the top cover frame 128 through the second pipeline 1211 to preliminarily cool it, and gradually draws the cooling water stored in the inner wall of the water storage tank 127 to slowly fill the inner wall of the closed part of the top cover frame 128 and the middle part of the inner side of the metal casting placing mechanism 2. In the process of gradually filling the cooling water, the inner wall of the closed part of the top cover frame 128 and the middle part of the inner side of the metal casting placing mechanism 2 forms a relatively sealed cooling space, which can effectively prevent the rapid evaporation of the cooling water, thereby ensuring the persistence of the cooling effect. With the continuous injection of cooling water, the temperature of the surface of the aluminum alloy casting begins to drop rapidly. Since there is a temperature difference between the cooling water and the surface of the casting,Heat will be transferred from the high temperature of the casting surface to the low temperature of the cooling water, achieving rapid cooling of the aluminum alloy casting, while when the inner wall cooling water of the closed part of the top cover frame 128 and the inner side of the middle part of the metal casting placing mechanism 2 is affected by the temperature of the aluminum alloy casting, causing the temperature of the cooling water to rise, the water tank 1210 will timely suck back the heated cooling water through the two second pipelines 1211, avoiding the continuous wrapping of the casting by high temperature water affecting the cooling efficiency, at the same time, the water storage tank 127 continuously supplements low temperature cooling water to the top cover frame 128 through the pipeline 126, forming a dynamic circulating cooling system, which can accurately adjust the cooling environment temperature around the casting by controlling the injection speed and extraction frequency of the cooling water, ensuring uniform and stable cooling process.
