Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a temperature gradient cooling device for a casting. Background Art

[0002] Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then waiting for it to cool and solidify to obtain a part or blank. During the casting process, the casting needs to be cooled. It needs to be initially cooled and formed in the casting mold, and then the casting is taken out and further cooled to room temperature. After it is completely cooled, the casting can be transported to the next workstation for further processing.

[0003] A search revealed a temperature-gradient cooling device for castings with announcement number CN219986203U, which includes an air-cooling box, a spray box, a water pool, and a variable-pitch conveyor mechanism. The variable-pitch conveyor mechanism includes two sets of parallel chain conveyor belts, the movement direction of which is perpendicular to the conveying direction of the chain conveyor belts. The air-cooling box and the spray box are arranged in sequence along the conveying direction of the variable-pitch conveyor mechanism. The air-cooling box has an air-cooling window for the variable-pitch conveyor mechanism to pass through, and the spray box has a water-cooling window for the variable-pitch conveyor mechanism to pass through. The water pool is located at the output end of the variable-pitch conveyor mechanism. The air-cooling box, spray box, and water pool gradually reduce the cooling temperature of the castings. This gradual temperature reduction method further cools the castings, significantly reducing the production defect rate of castings.

[0004] Based on the above patent, a water pool is arranged at the output end of the variable-pitch conveying mechanism, and the air cooling box, spray box, and water pool gradually reduce the cooling temperature of the casting. The use of a gradual temperature reduction method to further cool the casting significantly reduces the production defect rate of castings. However, after the castings are placed in the water pool and cooled, it is difficult to remove the castings from the water. In response to this technical problem, this application proposes a temperature-gradient cooling device for castings. Utility Model Content

The two supporting boxes are then driven by the rotating two-way threaded rod to move toward or away from each other, which can better adapt to castings of different sizes.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a temperature gradient cooling device for a casting, comprising a support frame, two support boxes being slidably connected to the top side of the support frame, the middle ends of the two support boxes being connected by a driving assembly, the middle end of the support frame being fixedly connected to a cooling chamber 2, the rear end of the support frame being fixedly connected to a cooling chamber 3, the inner walls of the two support boxes being rotatably connected to a plurality of rotating rollers, the outer walls of the rotating rollers at the front and rear ends being connected by a metal mesh belt, the rear end of the cooling chamber 3 being fixedly connected to a water tank, a placement rack being provided on the bottom side of the water tank, and the rear end of the placement rack being connected to the water tank by a lifting assembly.

[0008] Furthermore, the front ends of the two support boxes on the adjacent sides are each equipped with a second motor via a fixing frame, and the driving ends of the two second motors are fixedly connected to the adjacent sides of the two rotating rollers at the front ends.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0023] Specifically, the two support boxes 5 can be driven to slide on the support frame 1 by rotating the two-way threaded rod 14, and the distance between the two support boxes 5 can be adjusted by rotating the two-way threaded rod 14 forward and reverse, which is convenient for adjusting the distance between the two support boxes 5 according to the sizes of castings of different sizes, thereby improving the practicality of the cooling device. At the same time, the metal mesh belt 7 can withstand high-temperature castings and transport them. When the metal mesh belt 7 transports the castings, the rotating roller 6 in the middle can support the metal mesh belt 7 to keep transporting the castings, thereby preventing the castings from being transported to the cooling chamber 2 3. When inside, the metal mesh belt 7 is bent, which affects the transportation of the casting. The casting is cooled at different temperatures through cooling chamber 1 2, cooling chamber 2 3 and cooling chamber 3 4 using different cooling methods, thereby achieving a temperature gradient cooling effect. Finally, the casting is transported to the inside of the water tank 8 by the metal mesh belt 7, and the casting slides to the top side of the placement rack 15 through the slope 12. The cooled casting can be driven by the motor 11 to drive the rotation of the one-way threaded rod 10 to control the lifting and lowering of the placement rack 15, so as to control the placement rack 15 to take out the cooled casting.

[0024] Reference Figure 1-Figure 3 , a bidirectional threaded rod 14 is located at the middle end of the cooling chamber 2 3, the middle ends of the two support boxes 5 are threadedly connected to the outer wall of the bidirectional threaded rod 14, the left end of the bidirectional threaded rod 14 is fixedly connected to the turning handle 9, the front ends of the two support boxes 5 on the adjacent side are installed with motor 2 13 through a fixed frame, the driving ends of the two motors 2 13 are fixedly connected to the adjacent side of the two rotating rollers 6 at the front end, a unidirectional threaded rod 10 is located at the rear end of the water tank 8, a placement rack 15 is threadedly connected to the outer wall of the unidirectional threaded rod 10, a motor 11 is installed on the top side of the water tank 8 through a fixed frame, the driving end of the motor 11 is fixedly connected to the top of the unidirectional threaded rod 10, a ramp 12 is fixedly connected to the front end of the water tank 8, the ramp 12 is arranged at the rear ends of the two support boxes 5, a slide rail is arranged on the inner wall of the rear end of the water tank 8, and the placement rack 15 is slidably connected to the inside of the slide rail;

By starting the motor 2 13, the rotating roller 6 is driven to rotate and drive the metal mesh belt 7 to transport the castings. At the same time, the metal mesh belt 7 drives the castings to pass through the interior of the cooling chamber 1 2, the cooling chamber 2 3 and the cooling chamber 3 4 in sequence, thereby realizing gradual cooling of the castings. The castings are then driven by the transportation of the metal mesh belt 7 to slide the castings to the top side of the placement rack 15 through the sliding of the ramp 12, and then the motor 1 1 is started to drive the rotation of the unidirectional threaded rod 10 to drive the placement rack 15 to rise and fall, thereby driving the castings above to rise and fall, thereby facilitating the removal of the castings.

[0026] Working principle: First, the two-way threaded rod 14 is rotated by turning the handle 9 to drive the two support boxes 5 to move on the top side of the support frame 1, so as to adjust the distance between the two support boxes 5 according to the size of different castings, so as to improve the practicality of the cooling device. The castings are transported through the cooling chamber 1 2, the cooling chamber 2 3 and the cooling chamber 3 4 in sequence by the metal mesh belt 7, and then the castings are transported through the slope 12 to the inside of the water tank 8 by the metal mesh belt 7, and at the same time reach the top side of the placement rack 15, and then the rotation of the one-way threaded rod 10 is driven by starting the motor 11 to control the lifting and lowering of the placement rack 15 inside the water tank 8, so as to realize the scooping out of the cooled castings from the inside of the water tank 8.
