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] After the casting is produced, a cooling device is needed to cool it.

[0003] In the prior art, a temperature gradient cooling device for a casting with announcement number CN219986203U adopts a scheme that "includes an air cooling box, a spray box, a water pool and a variable-pitch conveying mechanism. The variable-pitch conveying mechanism includes two sets of parallel chain conveyor belts. The moving direction of the chain conveyor belt is perpendicular to its own conveying direction. The air cooling box and the spray box are arranged in sequence along the conveying direction of the variable-pitch conveying mechanism. The air cooling box is penetrated by an air cooling window for the variable-pitch conveying mechanism to pass through. The spray box is penetrated by a water cooling window for the variable-pitch conveying mechanism to pass through. The water pool is arranged at the output end of the variable-pitch conveying mechanism. The air cooling box, the spray box and the water pool gradually reduce the cooling temperature of the casting." This scheme adopts a gradual cooling method with gradually decreasing temperature to further cool the casting, which greatly reduces the production defect rate of castings.

[0004] However, the above scheme still has some shortcomings. For example, when the casting finally enters the water pool for final cooling, the cooling device first needs to manually salvage the casting after cooling is completed, which is a large workload. That is, there is a defect that the casting cannot be automatically salvaged after complete cooling. Secondly, since the water in the water pool is stagnant water, the cooling efficiency of the casting in the water pool is low.

[0005] In view of this, the utility model proposes a temperature gradient cooling device for castings. Utility Model Content
