[0002] Molding sand is the material used to make sand molds during the casting process. It is an indispensable part of the casting process. The main function of molding sand is to provide a mold so that molten metal can be poured into it, and then form the desired casting shape after cooling and solidification. Molding sand needs to have certain properties such as strength, air permeability, refractoriness and disintegration to ensure the quality and precision of the casting.

[0003] The recycling of molding sand is an important measure in the foundry industry to improve resource utilization, reduce costs and reduce environmental pollution. The molding sand needs to be cooled after use, mainly to enable the castings to be safely removed from the molding sand and to recycle and reuse the molding sand.

[0004] Generally, the molding sand is cooled by air cooling. However, the molding sand needs to be placed for a period of time after use before it can be recycled, crushed, etc., which not only increases the recycling time of the molding sand, but also has a poor cooling effect. In addition, the staff needs to crush it after cooling, which not only increases the work intensity of the staff, but also affects the recycling of the molding sand if the crushing effect is not up to standard. Therefore, a cooling treatment device for recycling molding sand is proposed. Utility Model Content

[0026] In order to facilitate the primary crushing and preliminary cooling of the used molding sand and effectively improve the quality of the recycling of the molding sand, the surface of the rotating shaft 5 is connected to the belt 15 through a pulley transmission, the belt 15 is connected to the transmission rod 16 through a pulley transmission, the surface of the transmission rod 16 is fixedly connected to the cam 17, a sliding column is arranged below the cam 17, and one end of the sliding column is fixedly connected to a blanking plate 18.

[0027] In order to facilitate the crushing of the lumped molding sand, the unloading plate 18 is rotatably connected to the hanging platform 3 through a pin shaft, and a friction rod 19 is rotatably connected inside the unloading plate 18. One end of the friction rod 19 is frictionally connected to the working shell 1, and a plurality of groups of crushing leaves 20 are arranged on the surface of the friction rod 19.

[0028] In order to improve the stability of the upper and lower sand boxes when they are struck, and to protect both and increase their service life, a plurality of groups of splints are arranged inside the hanging platform 3, a plurality of groups of spring columns are arranged between the splints and the hanging platform 3, the rotating shaft 5 is rotatably connected to the working shell 1, and a reset element is arranged between the sliding column fixed inside the unloading plate 18 and the working shell 1.

[0029] Furthermore, in order to facilitate the cooling of the molding sand and speed up the subsequent processing efficiency of the molding sand, the discharge port of the blanking plate 18 is located directly above the collecting box 2, and two groups of piston cylinders 22 are fixedly connected to the inside of the working shell 1, and the inside of the piston cylinder 22 is slidably connected to the piston rod 21, and the surface of the piston cylinder 22 is fixedly connected to a liquid spray pipe, and a plurality of liquid spray ports are arranged on the surface of the liquid spray pipe.

[0032] Working principle and use process of the utility model: After the utility model is installed, first add the treated water into the water tank 14, then insert the upper sand box and the lower sand box into the inside of the hanging platform 3 respectively, and then start the motor 4 to rotate and drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 will drive the eccentric wheel 6 to rotate. Since the side of the eccentric wheel 6 away from the rotating shaft 5 will continuously rotate inside the rotating sleeve 7, it can drive the rotating sleeve 7 to rotate at a certain angle. Since the rotating sleeve 7 can continuously drive the short swing rod 9 to rotate at a certain angle while swinging, The short swing rod 9 and the matching rod 11 are fixedly connected, and the rotation of the short swing rod 9 can drive the matching rod 11 to swing. When the matching rod 11 swings, the pressure rod 12 can be driven to swing through the pin shaft. At the same time, when the pressure rod 12 swings, it can be limited by the long swing rod 10, so that the pressure rod 12 can move up and down at the same time. The up and down movement of the pressure rod 12 can drive the knocking block 13 to knock on the surface of the upper and lower sand boxes, which can shake off the molding sand, and can avoid direct contact with the staff, resulting in burns, etc., with high safety.

[0033] The vibrated molding sand will fall inside the blanking plate 18, and at the same time, the rotating shaft 5 rotates to drive the belt 15 to rotate through the pulley, and the belt 15 rotates through the pulley to drive the transmission rod 16 to rotate, and the transmission rod 16 rotates to drive the cam 17 to rotate. The rotation of the cam 17 will push the blanking plate 18 at one end of the sliding column to swing around the pin shaft, which is convenient for shaking the fallen molding sand, not only to crush it, but also to accelerate its cooling effect;

[0034] At the same time, when the lower plate 18 swings, the friction rod 19 will be driven to swing. When the friction rod 19 swings, it will slide inside the working shell 1, contact with the friction pad provided inside the working shell 1, and rotate. The rotation of the friction rod 19 can drive the crushing blade 20 to rotate inside the lower plate 18, which can further crush the molding sand and improve its cooling effect.

[0035] When the long swing arm 10 and the matching rod 11 drive the knocking block 13 to move, the upper and lower sand boxes are continuously knocked. When the molding sand falls into the inside of the blanking plate 18, the long swing arm 10 and the matching rod 11 will push one group of piston rods 21 to slide inside the piston cylinder 22. When the long swing arm 10 and the matching rod 11 swing to the other side, the other group of piston rods 21 can be pushed to slide inside the piston cylinder 22, and the water inside the water tank 14 can be sprayed into the falling molding sand in the form of water mist, which can not only speed up the cooling speed, but also control the amount of water mist sprayed, so as to ensure the quality of the molding sand and the subsequent use effect.
