Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy casting processing, in particular to a device for quickly cooling aluminum alloy castings. Background Art

[0002] Aluminum alloy castings refer to equipment and devices made of pure aluminum or aluminum alloys obtained by casting. Aluminum alloy castings are very common and are also widely used in photovoltaic inverters and new energy vehicle power supplies.

[0003] Aluminum alloy castings undergo a cooling step during the production process to cool the aluminum alloy castings after casting. In the prior art, a collection frame containing the aluminum alloy castings is often directly placed in cold water to cool the aluminum alloy castings. However, the aluminum alloy castings are generally placed in a certain position in a pool. During the cooling process, the water temperature in this area will increase, which has a poor cooling effect on the aluminum alloy castings. At the same time, the temperature of the pool in this area increases after cooling. When cooling the next batch of aluminum alloy castings, the water temperature in this area cools down slowly, further affecting the cooling effect of multiple batches of aluminum alloy castings.

[0021] The second pulley 11 is driven to rotate by the first motor 10, and the transmission installation of the second pulley 11 and the first pulley 9 by the first transmission belt 12 will drive the installation rod 8 to rotate, and then drive one of the sprockets 3 to rotate, and the transmission between the two sprockets 3 by the chain 4 will drive the collection frame carrying the aluminum alloy casting to move inside the cooling water pool 1.

[0022] like Figures 1 to 3 As shown, a third pulley 13 is fixedly installed at one end of the stirring blade 7, a fourth pulley 14 is fixedly installed at the end of the mounting rod 8 corresponding to the position of the third pulley 13, and a second transmission belt 15 is installed between the fourth pulley 14 and the third pulley 13.

[0023] During the cooling process of the aluminum alloy casting, the mounting rod 8 rotates continuously, and the second transmission belt 15 drives the stirring blade 7 to rotate between the fourth pulley 14 and the third pulley 13 .

[0024] like Figures 1 to 3 As shown, screws 16 are symmetrically installed at both ends of the cooling water pool 1 through mechanical seals, and limiting rods 17 are symmetrically fixedly installed at both ends of the cooling water pool 1. The two limiting rods 17 are slidingly connected to the placement plate 6, and the placement plate 6 is threadedly connected to the screw 16.

[0030] The utility model provides a rapid cooling device for aluminum alloy castings, and the specific working principle is as follows:

[0031] When the device is in use, the collection frame carrying the aluminum alloy castings is placed on one of the placement plates 6, and the collection frame is hung on the hook 5. The screw 16 is driven to rotate by the second motor 18.

Moving inside the cooling water pool 1, the aluminum alloy castings will be cooled by the water in the entire cooling water pool 1, and then the collection frame carrying the aluminum alloy castings will be controlled to move to the placement plate 6 at the other end of the cooling water pool 1.

The screw 16 is driven to rotate by the operation of the second motor 18, and the transmission between the two transmission wheels 19 through the transmission belt 20 will drive the other screw 16 to rotate. Since the thread directions of the two screws 16 are opposite, the other placement plate 6 will rise, which is used to raise the collection frame carrying the aluminum alloy castings;

[0032] During the cooling process of the aluminum alloy casting, the mounting rod 8 rotates continuously, and the transmission between the fourth pulley 14 and the third pulley 13 by the second transmission belt 15 will drive the stirring blade 7 to rotate, which is used to mix the cold and hot water in the cooling water pool 1, so as to further improve the cooling effect of the aluminum alloy casting.
