The S-shaped pipe 2 can be used to cool the cooling water during the reflux process and re-spray it on the aluminum alloy casting to cool it, so that it can be recycled repeatedly to avoid excessive consumption of water resources.

[0024] Rotation holes 9 are provided on both sides of the cooling box 1; a pair of the rotation holes 9 are rotatably connected with threaded barrels 10; a pair of the threaded barrels 10 are threadedly connected with threaded rods 11; a pair of the threaded rods 11 are fixedly connected with clamping blocks 12 on opposite ends; a pair of the threaded rods 11 are fixedly connected with rotary valves 13 on ends away from each other; a rotating member is provided in the fixed shell 6; the rotating member is used to drive the threaded barrel 10 to rotate, and a pair of the threaded barrels 10 are provided with limiting members; the limiting members are used to limit the rotation of the pair of threaded barrels 10. During operation, after the aluminum alloy casting is clamped by the provided threaded rods 11 and the clamping blocks 12, the pair of threaded barrels 10 can be driven to rotate by the provided rotating member, so that the aluminum alloy casting can be rotated, so that the aluminum alloy casting can be evenly cooled during the cooling process, avoiding the concentration of thermal stress of the aluminum alloy casting due to the uneven cooling of various parts during the cooling process, causing cracks and deformation on the surface of the aluminum alloy casting.

[0025] The rotating member includes a first rotating rod 14; the first rotating rod 14 is rotatably connected between the opposite side walls of the fixed shell 6, and both ends of the first rotating rod 14 penetrate the fixed shell 6 and the L-shaped block 4; both ends of the first rotating rod 14 are fixedly connected to a first sprocket 15; a pair of the threaded cylinders 10 are fixedly connected to a second sprocket 16; the first sprocket 15 is connected by a first chain 17; a rotating wheel 18 is fixedly connected to the first rotating rod 14, and the rotating wheel 18 is located in the fixed shell 6. When working, the cooling water is driven to rise by the water pump 3, and the rotating wheel 18 is driven to rotate by the impact of the cooling water, thereby driving the first rotating rod 14 to rotate, that is, when the water pump 3 drives the cooling water to spray the cooling water, the transmission is carried out by the first sprocket 15, the second sprocket 16 and the first chain 17, so that the pair of threaded cylinders 10 can be driven to rotate, that is, the pair of threaded cylinders 10 can be driven to rotate by the power of water, so that it can be operated with a lower operating cost.

[0026] The limiting member includes a limiting rod 19; a pair of limiting rods 19 are respectively fixed to a pair of threaded barrels 10; a fixing block 20 is fixed to both sides of the cooling box 1; a pair of fixing blocks 20 are each provided with a first plug hole 21; a pair of limiting rods 19 are each provided with a second plug hole 22; a pair of fixing blocks 20 are each provided with a limiting groove 23; the first plug hole 21 corresponds to the second plug hole 22; a plug 24 is placed in the first plug hole 21 and the second plug hole 22.

After the aluminum alloy casting is clamped by the threaded rod 11 and the clamping block 12, the pair of threaded cylinders 10 can be driven to rotate by the rotating member, so that the aluminum alloy casting can be rotated, so that the aluminum alloy casting can be cooled during the cooling process. , it can be cooled evenly, and the aluminum alloy casting can be prevented from being subjected to the heat stress concentration of the aluminum alloy casting due to the uneven cooling of various parts during the cooling process, which causes cracks and deformation on the surface of the aluminum alloy casting. The cooling water is driven up by the water pump 3, and the impact of the cooling water drives the rotating wheel 18 to rotate, thereby driving the first rotating rod 14 to rotate, so that the water pump 3 drives the cooling water to spray the cooling water. The transmission is carried out through the first sprocket 15, the second sprocket 16 and the first chain 17, and the pair of threaded barrels 10 can be driven to rotate, and the power of water can drive the pair of threaded barrels 10 to rotate. The threaded barrel 10 can be rotated, so that it can be operated at a lower operating cost. The cooperation of the limiting rod 19, the fixing block 20 and the latch 24 can be used to limit the rotation of the threaded rod 11 when the staff needs to rotate the threaded rod 11 to clamp the aluminum alloy casting. The latch 24 is inserted into the first plug hole 21 and the second plug hole 22 to limit the rotation of the threaded barrel 10, thereby preventing the staff from driving the threaded barrel 10 to rotate at the same time when rotating the threaded rod 11, and failing to clamp the aluminum alloy casting. When the threaded barrel 10 needs to rotate, the latch 24 can be pulled out, and the L-shaped filter plate 26 can filter Impurities and particles in the cooling water can be removed, the cooling water for reflux utilization can be kept clean, and impurities and particles can be prevented from causing wear and blockage to the S-shaped tube 2. The setting of the L-shaped filter plate 26 can facilitate the staff to collect impurities and particles, so that the staff can collect and process them. The bottom of the cooling box 1 is an inclined surface, so that the water used for cooling can pass through the inclined surface of the cooling box 1 to gather on one side of the cooling box 1, thereby facilitating the water pump 3 to extract the cooling water, making the cooling water easier to be extracted, and allowing the impurities that fall on the aluminum alloy to gather on the horizontal end of the L-shaped filter plate 26, so that the staff can clean it up later.
