Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1-Figure 4 , the utility model provides an embodiment: an aluminum alloy die-casting air cooling device, comprising a shell 1, a water inlet pipe 9 is fixedly connected to the top of the shell 1, and a cover plate is threadedly connected to the outer periphery of the water inlet pipe 9, water can be injected into the shell 1 through the water inlet pipe 9, and the water inlet pipe 9 can be blocked by the cover plate, thereby preventing dust from entering the interior of the shell 1 and causing water pollution.

The heat exchanger 7 can be used to cool the water when the water circulates once, so as to prevent the water from being affected by the air temperature in the circulating water pipe 3 and causing the water temperature to drop. A filter plate 14 is fixedly connected to one side of the shell 1, and the filter plate 14 can filter the dust and impurities in the air before the air enters the shell 1, so as to prevent the dust and impurities from entering the shell 1.

[0036] Reference Figure 1 A plurality of heat dissipation fins 13 are fixedly connected to the outer side of the shell 1, and the heat in the shell 1 can be discharged through the heat dissipation fins 13, thereby further reducing the temperature of the water. An air intake assembly 10 is fixedly connected to the side of the shell 1 away from the filter plate 14.

[0037] Reference Figure 1-Figure 3 The air intake component 10 is composed of an air pump and an air intake pipe, wherein the air intake pipe is fixed at the input end of the air pump. The cooled air inside the shell 1 will blow the die casting through the output end of the air pump, thereby improving the cooling effect on the die casting, while improving the cooling efficiency of the die casting, thereby improving the production efficiency of the die casting, and the other end of the shell 1 is fixedly connected with a diversion component.

[0038] Reference Figure 2 and Figure 3 The diversion assembly includes a guide box 11, which is fixedly connected to one end of the air intake assembly 10 away from the shell 1. A diversion plate 12 is fixedly connected to the middle of the guide box 11. The guide box 11 is rotatably connected to the outside of the shell 1. The cooled air can be evenly blown to the die-casting through the guide box 11 and the diversion plate 12, further improving the cooling effect of the die-casting. At the same time, the angle of the guide box 11 can be adjusted, so that the center position of the air flow can be aligned with the die-casting.

[0039] Reference Figure 3 , Figure 5 and Figure 6 The middle of the shell 1 is fixedly connected with a filter plate 2 15, through which the water entering the shell 1 can be filtered, which can prevent larger solid impurities in the water from entering the shell 1 and the water pump 2, and prevent impurities from entering the water pump 2 and causing damage to the water pump 2, thereby improving the service life of the water pump 2. The middle of the shell 1 is slidably connected with a shell 17, and a limiting groove 24 is provided in the middle of the shell 1. The shell 17 is slidably connected to the middle of the limiting groove 24. The limiting groove 24 can limit the shell 17, which can prevent The shell 17 slides out of the middle part of the shell 1 when moving, and a compression spring 18 is fixedly connected to the inside of the shell 17, and a scraper 19 is fixedly connected to the other end of the compression spring 18, and the scraper 19 is in contact with the filter plate 15. The outer side of the shell 1 is rotatably connected to a flap 16, and the scraper 19 is in contact with the flap 16. A pull rod 20 is fixedly connected to the outer side of the shell 17, and the pull rod 20 is slidably connected to the middle part of the shell 1, and a stopper 21 is fixedly connected to the end of the pull rod 20 away from the shell 17, and the stopper 21 is in contact with the flap 16.

[0040] Reference Figure 3 , Figure 5 and Figure 6, by pulling the stopper 21 and under the action of the pull rod 20, the shell 17 and the scraper 19 can be moved at the same time. During the movement, the impurities filtered on the top of the filter plate 2 15 can be discharged into the shell 1 to prevent the filter plate 2 15 from being blocked. The scraper 19 can be squeezed by the compression spring 18, thereby improving the cleaning effect of the scraper 19 on the filter plate 2 15. At the same time, after cleaning, the cleaning port can be blocked by the flap 16, and the flap 16 can be restricted by the stopper 21 to prevent the flap 16 from turning over, thereby preventing water leakage. The shell 17 is slidably connected with a partition inside, and the partition is fixedly connected between the compression spring 18 and the scraper 19. The scraper 19 can be limited by the partition, thereby preventing the scraper 19 from tilting during the movement, avoiding the problem of deformation and damage caused by the compression spring 18 being tilted and squeezed, and the service life of the compression spring 18 can be improved. A sealing component is arranged between the flap 16 and the shell 1.

The sealing ring 22 and the groove 23 can improve the sealing between the flap 16 and the outer shell 1 to avoid leakage of water and air.

[0042] Working principle: When in use, water can enter the circulating water pipe 3 by driving the water pump 2 and drive the water wheel 5 and the fan blades 6 to rotate. At this time, the air can enter the outer shell 1 after being filtered by the filter plate 14. At the same time, the water itself can be cooled by the heat exchanger 7 and the heat dissipation fins 13 during the water circulation process, which can prevent the problem of water temperature rising during circulation. At this time, when the water flows inside the circulating water pipe 3, the outer periphery of the circulating water pipe 3 will emit cold air, which will affect the incoming air, thereby reducing the temperature of the air. The cooled air can be blown to the die-casting through the air suction component 10, thereby improving the cooling effect on the die-casting, and at the same time improving the cooling efficiency of the die-casting, thereby improving the production efficiency of the die-casting.

[0043] Among them, the water entering the outer shell 1 can be filtered through the filter plate 15 to prevent larger solid impurities in the water from entering the outer shell 1 and the water pump 2. The pull rod 20 can drive the shell 17 to move by pulling the stopper 21. When the shell 17 moves, the scraper 19 can discharge the impurities filtered on the top of the filter plate 15 into the outer shell 1, thereby preventing the filter plate 15 from being blocked. At the same time, the cleaning port can be sealed by the flap 16 after cleaning, and the flap 16 can be restricted by the stopper 21 to prevent the flap 16 from turning over, thereby preventing water leakage.
