Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts production, in particular to a cooling mechanism for automobile die casting production. Background Art

[0002] Die casting is a process that uses a pressure casting machine with a casting mold installed to cast the heated liquid metal into a metal part with a shape and size limited by the mold. Since die castings can be made into complex shapes with high precision and finish, they are widely used in the production of automotive parts. After the die casting is demolded, it needs to be cooled to facilitate subsequent assembly.

[0003] In the Chinese patent "A Cooling Device for Automobile Die Casting Production" with publication number CN219561387U, by arranging a cooling mechanism in the conveying base, dust can be effectively prevented from entering the interior of the cooling air chamber through the air inlet channel, thereby ensuring the purity of the gas blown out by the cooling fan and reducing the risk of casting contamination. However, the above patent can only use the cooling fan to cool the die casting from directly above. However, there are many shapes of die castings used in automobiles. If cooling is only carried out from directly above, the cooling efficiency is not high enough, which may cause the temperature drop rate on the top to be higher than the temperature drop rate on the side.

[0004] Therefore, we propose a cooling mechanism for automobile die casting production to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1 - Figure 4 As shown, a cooling mechanism for automobile die casting production includes a conveyor belt 1 and a plurality of annular blocks 2. The conveyor belt 1 passes through the plurality of annular blocks 2. The width of the conveyor belt 1 is smaller than the diameter of the annular block 2. The movement of the cooling fan 7 inside the annular block 2 cannot contact the conveyor belt 1, so the diameter of the annular block 2 needs to be set slightly larger to facilitate the movement of the cooling fan 7. A support leg 3 is fixedly connected to the bottom of the annular block 2, a movement groove 4 is provided in the annular block 2, an annular rack 5 is slidably connected in the movement groove 4, sliding rods 12 are fixedly connected to the side walls of the annular rack 5 on both sides, and sliding grooves 13 are provided on the side walls of the movement groove 4 on both sides. Two sliding rods 12 are slidably connected to the inner walls of the two sliding grooves 13, respectively. The cooperation between the sliding rod 12 and the sliding groove 13 allows the annular rack 5 to stably move in the annular block 2.

[0022] The side wall of the annular rack 5 is fixedly connected with a connecting rod 6, and one end of the connecting rod 6 away from the annular rack 5 is fixedly connected with a cooling fan 7. A hollow groove 8 is provided on the side wall of the supporting leg 3, and the hollow groove 8 is located below the annular rack 5. A rotating rod 9 is rotatably connected in the hollow groove 8, and a driving gear 10 is fixedly connected to the side wall of the rotating rod 9, and the driving gear 10 is meshed with the annular rack 5. One end of the rotating rod 9 passes through the side wall of the hollow groove 8 and is fixedly connected with a hand wheel 11.

[0023] A fixing assembly for limiting the driving gear 10 is installed at the bottom of the slot 8, and the fixing assembly includes a center rod 14, a rotating rack 15, a pedal 16 and a telescopic spring 17. A swinging groove 18 is provided at the bottom of the slot 8, and the center rod 14 is fixedly installed inside the swinging groove 18. One end of the rotating rack 15 is rotatably connected to the side wall of the center rod 14. The end of the rotating rack 15 away from the pedal 16 is designed in an arc shape. The center rod 14 passes through the arc-shaped part of the rotating rack 15. In order to facilitate the rotating rack 15 to rotate around the center rod 14, it is best to set the part of the rotating rack 15 that contacts the center rod 14 to an arc shape. The other end of the rotating rack 15 is fixedly connected to the side wall of the pedal 16. The width of the pedal 16 is greater than the width of the rotating rack 15, and the thickness of the pedal 16 is less than the thickness of the rotating rack 15. The rotating rack 15 is meshed with the driving gear 10, one end of the telescopic spring 17 is fixedly connected to the bottom wall of the rotating rack 15, and the other end is fixedly connected to the bottom wall of the swing groove 18. The force applied to the rotating rack 15 by the telescopic spring 17 will keep the rotating rack 15 in meshing state with the driving gear 10.

[0024] The working principle is as follows: first, the die casting is placed on the conveyor belt 1. During the movement of the die casting, the staff needs to adjust the position of the cooling fan 7 according to the shape of the die casting;

[0025] The staff first presses or steps on the pedal 16 so that the rotating rack 15 fixedly connected to the pedal 16 can rotate around the center rod 14. While compressing the telescopic spring 17, the driving gear 10 loses the restriction from the rotating rack 15. Then the staff can turn the hand wheel 11 to make the hand wheel 11 drive the driving gear 10 to rotate through the rotating rod 9. The annular rack 5 meshing with the driving gear 10 will move in the annular block 2, and the connecting rod 6 fixedly connected to the side wall of the annular rack 5 will drive the cooling fan 7 to move to a suitable angle, thereby cooling the die-casting.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
