DETAILED DESCRIPTION

[0029] The application is further described in conjunction with the specific embodiments. It should be understood that these embodiments are only used to explain the application and not used to limit the scope of the application. Furthermore, it should be understood that after reading the content of the application, those skilled in the art can make various modifications or changes to the application, and these equivalent forms also fall within the scope defined by the application.

[0030] REFERENCE Figure 1 AND Figure 3The application discloses a cooling device for casting processing, which comprises a cooling box and a conveying line above the cooling box. The conveying line is welded or bolted to the roof of a cooling place by a plurality of hangers, so that the conveying line can be suspended and transported. The cooling box is below the conveying line and has an open top. When the casting moves along the conveying line, the casting can enter the cooling box for cooling. A hanging rack is slidably connected to the conveying line. The longitudinal section of the conveying line is in the shape of an inverted T. The hanging rack is slidably connected to the bottom of the conveying line. A plurality of moving wheels are rotatably connected to the hanging rack by bearings. The moving wheels are in rolling contact with the bottom of the conveying line. Therefore, the external power chain can pull the hanging rack to move along the conveying line, so that the casting can be continuously transported. Hooks are arranged on the bottom of the hanging rack for hanging the casting. A sliding sleeve is welded or bolted to the bottom of the hanging rack. The sliding sleeve is in the shape of a pipe. A sliding rod is slidably connected to the inside of the sliding sleeve. A compression spring is arranged between the sliding rod and the sliding sleeve. The sliding rod is inside the sliding sleeve under the action of the compression spring. Therefore, the sliding rod and the sliding sleeve are arranged at a high position to suspend and transport the casting. The space below the conveying line is not occupied, so that the space utilization is improved. A fixing seat is welded or bolted to the sliding rod. Symmetrical guide wheels are rotatably connected to the fixing seat by bearings. Symmetrical guide rails are welded or bolted to the top of the cooling box. The sliding rod passes through the area between the two guide rails. The guide wheels on the two sides of the fixing seat are in rolling contact with the bottom of the guide rail, so that the guide wheels can move along the guide rail. Symmetrical transition portions are welded or bolted to the two ends of the guide rail. The transition portions are inclined. The transition portions are fixedly connected to the guide rail by welding or integral forming. The height of the transition portion gradually decreases along the direction of the guide rail. When the guide wheel enters the guide rail, the casting enters the inside of the cooling box. When the sliding rod and the fixing seat move along the conveying line and pass through the guide rail, the transition portion at the end of the guide rail first contacts the sliding rod and the fixing seat. The sliding rod and the fixing seat are pressed downward, so that the compression spring is compressed. The sliding rod and the fixing seat slide downward while moving along the conveying line. The guide wheels on the fixing seat roll along the transition portion and the guide rail, so that the advancing and descending process of the fixing seat is smoother. When the guide wheel rolls to the guide rail, the casting at the bottom of the sliding rod completely enters the inside of the cooling box, so that the casting in the relatively closed cooling box is cooled.The medium such as cooling water used for cooling is prevented from spilling to the surrounding environment, and the cleanness of the cooling and temperature reducing place is ensured. After the cooling and temperature reducing is completed, the guide wheel 9 is lifted along the transition part 11 at the other end of the guide rail 10 under the action of the compression spring 7, so that the casting is lifted and hung at the bottom of the conveying line 2 and continues to be conveyed forward, and the processing operation such as impurity removal after the casting is not affected, so that the whole cooling and temperature reducing process is more rapid and smooth.

[0031] A rotating seat 12 is rotatably connected to the slide rod 6 below the fixed seat 8 via a bearing. The rotating seat 12 can rotate around the center line of the slide rod 6. The hook 4 is fixed to the bottom end of the rotating seat 12 by welding or bolts, allowing the casting on the hook 4 to rotate along the bottom of the slide rod 6. This enables the cooling water and other cooling media in the cooling box 1 to be evenly sprayed onto various parts of the casting, thereby improving the uniformity of cooling the casting. A turntable 13 is fixed to the rotating seat 12 by welding or bolts, facilitating the rotation of the rotating seat 12 by the turntable 13. Both sides of the interior of the cooling box 1 are provided with drive chains 14 for driving the turntable 13 to rotate. The two drive chains 14 move in opposite directions. Multiple drive blocks 15 are arranged in an array on the 4th surface by welding or bolting. These drive blocks 15 contact the sides of the turntable 13. With this structure, after the casting enters the cooling box 1, the drive blocks 15 on the drive chains 14 on both sides of the cooling box 1 contact the sides of the turntable 13. The opposing movement of the drive chains 14 drives the turntable 13 to rotate, thus driving the casting to rotate. This ensures that the casting automatically enters a rotating and forward-moving state after entering the cooling box 1, making the entire cooling process faster and more uniform. The cooling box 1 is equipped with a spray chamber 16 and an evaporation chamber 17. The spray chamber 16 sprays cooling water or other cooling media onto the surface of the casting, while the evaporation chamber 17 sprays air towards the casting to remove excess water. Cooling media such as cooling water evaporate rapidly, carrying away heat from the casting surface during the evaporation process to achieve rapid cooling. Multiple spray nozzles 18 are symmetrically arranged within the spray chamber 16, connected to the cooling water inlet pipe, allowing for spray cooling of the rotating casting from both sides. The cooling water then removes heat from the casting through heat exchange. Multiple air jet nozzles 19 are symmetrically arranged within the evaporation chamber 17, connected to the air supply inlet pipe, allowing cooling gas to be sprayed from both sides onto the casting surface containing cooling water. This ensures rapid evaporation of the cooling water without affecting subsequent processing steps. Furthermore, the evaporation of the cooling water removes heat from the casting surface, resulting in a more uniform and efficient cooling method compared to traditional air cooling. At the bottom of component 17, a refrigerant tank 20 is provided, which stores vaporizable refrigerant substances such as dry ice. The refrigerant tank 20 has multiple refrigerant holes 21. After the refrigerant vaporizes, it is discharged from the refrigerant holes 21. Multiple exhaust fans are rotatably connected to the refrigerant tank 20 above the refrigerant holes 21. When the temperature of the casting is still high after cooling, the exhaust fans are used to quickly guide the vaporized refrigerant discharged from the refrigerant holes 21 to the bottom of the casting, so as to conduct a rapid heat exchange with the cooled casting again. At this time, the temperature of the casting has dropped significantly compared to before cooling. Therefore, the contact between the cooled casting and the refrigerant will not cause structural damage to the casting. The casting is cooled down quickly in a short time, making the overall cooling of the casting more uniform and efficient.
