Description

Technical Field

[0001] The utility model belongs to the technical field of casting auxiliary equipment, in particular to a casting rapid cooling device. Background Art

[0002] Castings are made by die-casting machines. According to the molds placed in the machine, liquefied metal liquid is injected into the mold under the action of a press to complete the casting of parts or blanks. The castings obtained by this method are called castings. After the castings are completed, the surface of the castings still has a relatively high temperature due to the solidification of the liquefied metal. In order to facilitate the quality inspection of the castings, the castings often need to be cooled. When using existing cooling devices, water-cooled immersion is often used to cool the produced castings. Because the castings carry a large amount of metal debris on the surface when they are cooled, the cooling water cannot be filtered during immersion cooling, so after long-term use, a large amount of metal debris will be deposited at the bottom of the device, which will reduce the total amount of cooling water and reduce the cooling efficiency of the device.

[0003] After searching, for example (authorization announcement number CN220515406U) a casting rapid cooling device, including a casing, a cooling water pool and a drying pool are respectively arranged on the left and right sides of the casing, and a lifting and conveying device is arranged on the upper part of the cooling water pool and the drying pool, and a lifting rod is fixedly connected to the upper part of the lifting and conveying device, and the lifting rod passes through the upper part of the casing and is fixedly connected to the lifting plate, and the top of the lifting plate is fixedly connected to the hydraulic cylinder, and the output end of the hydraulic cylinder passes through the lifting plate and is fixedly connected to the upper part of the casing, and the casing is located on the left side of the cooling water pool and is installed with a feed conveying device, and the casing is located on the right side of the drying pool and is installed with a discharge conveying device. The device solves the operational problems of the existing equipment distributed cooling and improves the cooling efficiency, but the device cannot filter the water used for cooling, so that a large amount of metal debris carried on the surface of the casting is immersed in the device, reducing the total amount of cooling water in the device, thereby reducing the cooling efficiency of the device after long-term use.

The collected and recycled coolant is dissipated by the heat sink fins, so as to always control the temperature of the cooling water inside the water tank 8 and improve the cooling efficiency of the device.

[0030] Both sides of the box body 1 are provided with through-type through grooves for easy connection, and a U-shaped fixing frame 6 is arranged in the through groove. The bottom wall of the fixing frame 6 is provided with a through hole for easy circulation of cooling water, and the inner bottom wall of the fixing frame 6 is in an arc-shaped inclined state as a whole. Through the action of the through hole, the coolant penetrating the conveyor belt 3 is gathered and concentrated until it is transported to the surface of the sieve plate 5 located at the bottom of the fixing frame 6. A conveyor belt 3 for convenient transportation of castings is rotatably connected to the inner wall of the fixing frame 6. A plurality of holes for drainage are arranged on the surface of the conveyor belt 3. A driving motor 7 for providing power is screwed to the side wall of the fixing frame 6. The output shaft of the driving motor 7 penetrates the side wall of the fixing frame 6 and is connected to the driving shaft of the conveyor belt 3. By controlling the drive of the driving motor 7, the conveyor belt 3 is driven to rotate inside the fixing frame 6.

[0038] When the operator uses the casting rapid cooling device, he opens the feed inlet 18 to add cooling water into the water tank 8, closes the sealing cover arranged on the top of the feed inlet 18, places the manufactured die-casting on the top of the conveyor belt 3, starts the output shaft of the driving motor 7 to rotate, drives the conveyor belt 3 to rotate in the fixed frame 6, and drives the casting to move inside the box body 1;

[0039] Start the pressure pump to deliver the cooling water in the water tank 8 to the inside of the hollow spray plate through the connected water outlet pipe 9. The spray plate sprays the cooling water evenly onto the surface of the casting through the nozzles at the bottom. The used cooling water is concentrated onto the surface of the sieve plate 5 through the holes and through holes.

[0040] The moving part of the linear motor 10 is controlled to move, driving the connecting plate 13 to move. The top screw of the moving plate 13 is connected to the electric push rod 14. The moving part of the electric push rod 14 is connected to the top of the fixed plate 11. The bottom of the fixed plate 11 is detachably connected to the brush plate 12. The brush plate 12 is slidably connected to the screen 16. The screen 16 is embedded in the screen plate 5. The cooling water carrying metal debris after use is filtered through the screen 16.

[0041] Finally, the filtered cooling water is circulated in cooperation with the water pump arranged on the bottom wall of the box body 1 and transported to the inside of the water tank 8 through the water inlet pipe 19, thus completing the cooling of the casting and the recycling of the cooling water.
