Description

TECHNICAL FIELD

[0001] The application relates to the technical field of aluminum alloy ingot casting, and particularly relates to an aluminum alloy ingot casting device. BACKGROUND

[0002] The aluminum alloy ingot is a basic raw material in the aluminum industry and is mainly formed through smelting and casting. The aluminum alloy ingot is not a terminal product directly used, but is an intermediate raw material, which is remelted, adjusted and utilized through processes such as die casting, extrusion and forging to be made into aluminum products and parts of various shapes and performances, and is widely applied to the fields of aerospace, transportation (automobiles, high-speed rails and ships), construction engineering, electronic appliances, packaging containers (pop cans) and the like. The aluminum alloy ingot has excellent characteristics such as light weight, high strength, corrosion resistance, good electrical conductivity and thermal conductivity and strong recyclability, and becomes an important metal indispensable to modern industry.

[0003] According to the search, the patent document with the publication number CN118404039A discloses a high-efficiency cooling device for recycled aluminum alloy ingot casting, which comprises a cooling liquid pool, and the inside bottom surface of the cooling liquid pool is fixedly connected with the bottom surface of the support frame of a conveying device.

[0004] The design fixes the bottom end of the cooling frame to the top surface of the cooling liquid pool, and when the high-pressure pump is opened, the cooling water in the cooling liquid pool is transported to the inside of the cooling water concentrating plate, so that the cooling water in the cooling liquid pool is sprayed to the top of the conveying device and transported to the surface of the aluminum alloy ingot through the spray head, thereby achieving rapid cooling of the aluminum alloy ingot after casting. However, in actual use, after the cooling water is sprayed to the surface of the aluminum alloy ingot to cool the aluminum alloy ingot, the cooling water remains on the surface of the aluminum alloy ingot. After the high-temperature or even only warm aluminum ingot surface contacts with water, a chemical reaction occurs. The water remains on the surface of the aluminum alloy ingot, and the reaction continues, resulting in uneven water stains, white spots, darkening or grayish corrosion products on the surface of the aluminum ingot, which seriously affects the appearance quality of the product.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Please refer to Figures 1 to 6 As shown in the figure, an aluminum alloy ingot casting device includes a mounting frame 1, a plurality of molds 22 are rotatably installed in the cavity of the mounting frame 1, a feed pipe 11 is fixedly installed on the top of the mounting frame 1, and a water tank 4 is fixedly installed on one side of the mounting frame 1; the device further includes a drying mechanism for drying the aluminum alloy ingot cooled by water; the drying mechanism includes a fan 61, the fan 61 is fixedly installed on one side of the water tank 4, an air pipe 62 is fixedly connected to one side of the fan 61, an electric heating wire is fixedly installed in the cavity of the air pipe 62, a plurality of air outlet pipes 63 are fixedly installed on the outer surface of the air pipe 62, a plurality of rollers 6 are rotatably installed in the cavity of the water tank 4, a connecting box 52 is fixedly installed on the top of the water tank 4, and a spray head 54 is fixedly connected to the bottom of the connecting box 52.

[0033] The prior art cools the aluminum alloy ingot through cooling water after casting, but in actual use, the water stains on the surface of the aluminum alloy ingot cannot be removed in time after the aluminum alloy ingot is cooled by the cooling water, and the residual water stains on the surface of the aluminum alloy ingot will chemically react with the surface of the aluminum alloy ingot, thereby causing white spots, darkening or grayish corrosion products on the surface of the aluminum alloy ingot, affecting the appearance quality of the aluminum alloy ingot.

[0034] In use, first, the molten aluminum is poured into the cavity of the mold 22 through the feed pipe 11. The feed pipe 11 needs to deliver molten aluminum to the cavities of multiple molds 22, so the movement speed of the mold 22 in the cavity of the mounting frame 1 is relatively slow. During the movement of the mold 22, the molten aluminum in the cavity of the mold 22 will solidify into an aluminum alloy ingot. As the mold 22 moves, the aluminum alloy ingot will separate from the mold 22 when the mold 22 with the aluminum alloy ingot moves to one end of the mounting frame 1. At this time, the aluminum alloy ingot will fall into the cavity of the water tank 4. The water on the surface of the aluminum alloy ingot is sprayed by the nozzle 54 to further cool the aluminum alloy ingot. Then the aluminum alloy ingot will slide to the top of the roller shaft 6. The roller shafts 6 are inclined, so the aluminum alloy ingot will slide on the top of the roller shaft 6 under the action of gravity. At this time, the air in the cavity of the air pipe 62 flows by blowing air into the cavity of the air pipe 62 through the fan 61. The electric heating wire in the cavity of the air pipe 62 can heat the air entering the cavity of the air pipe 62. Since the air pipe 62 is relatively long and the electric heating wire is installed in the cavity of the air pipe 62 in the shape of a spring, the electric heating wire can heat the air in the cavity of the air pipe 62. The heated air is sprayed out through the air outlet pipe 63. Then the hot air contacts the aluminum alloy ingot, which can blow off the water stains on the surface of the aluminum alloy ingot and dry the aluminum alloy ingot.

[0035] Further, as shown in Figure 2 The mounting frame 1 has two first conveying rollers 2 rotatably installed in the cavity. The outer surfaces of the two first conveying rollers 2 are jointly connected with a conveyor belt 21. One side of one of the first conveying rollers 2 is fixedly connected with a first motor 24, and the first motor 24 is fixedly installed on one side of the mounting frame 1.

[0036] The conveyor belt 21 is movably connected with the plurality of molds 22. Two limiting rods 23 are fixedly installed on one side of the mounting frame 1. Two connecting rods 12 are fixedly installed on the bottom of the mounting frame 1, and the connecting rods 12 are fixedly connected with the water tank 4.

[0037] In use, the first motor 24 outputs the first conveying roller 2 to rotate. When the first conveying roller 2 rotates, the plurality of molds 22 move together. When the mold 22 moves to the bottom of the feed pipe 11, the feed pipe 11 delivers molten aluminum to the cavity of the mold 22. As the mold 22 moves, the molten aluminum solidifies into an aluminum alloy ingot. When the aluminum alloy ingot moves to the other first conveying roller 2, the aluminum alloy ingot separates from the limiting rod 23.

[0038] Further, as shown in Figure 3 The installation frame 1 is fixedly installed with a second connecting rod 35 on both sides, and the two second connecting rods 35 are jointly rotatably connected with a discharging plate 36, and the two sides of the discharging plate 36 are rotatably connected with a first connecting rod 32.

[0039] The outer surface of the installation frame 1 is rotatably installed with two first discs 3, and the opposite surfaces of the two first discs 3 are jointly fixedly connected with a connecting shaft 31, and one side of the first disc 3 is fixedly connected with a cylinder 301, and the first connecting rod 32 is rotatably installed on the outer surface of the cylinder 301.

[0040] One side of the cylinder 301 is fixedly connected with a second disc 33, one side of the second disc 33 is fixedly connected with a second motor 34, and the second motor 34 is fixedly installed on one side of the installation frame 1.

[0041] In use, in order to avoid damage to the outer surface caused by the direct falling of the aluminum alloy ingot, the aluminum alloy ingot is dropped on the top of the discharging plate 36 after being separated from the mold 22, and in order to avoid the accumulation of the aluminum alloy ingot on the top of the discharging plate 36, the second motor 34 output shaft drives the second disc 33 to rotate, and the second disc 33 rotates to drive the cylinder 301 to make a circular motion, and the cylinder 301 is at the edge of the second disc 33, so that when the cylinder 301 makes a circular motion, the cylinder 301 pulls the first connecting rod 32, and the first connecting rod 32 further pulls the bottom of the discharging plate 36 to move, which can make the aluminum alloy ingot on the top of the discharging plate 36 slide down from the top of the discharging plate 36, so as to avoid the accumulation of the aluminum alloy ingot on the top of the discharging plate 36, and the limiting rod 23 can protect the aluminum alloy ingot, so that the aluminum alloy ingot is separated from the mold 22 and does not directly fall, but is limited by the limiting rod 23 to slide along the limiting rod 23 until it slides to the top of the discharging plate 36, and the aluminum alloy ingot is separated from the mold 22 and the limiting rod 23 and falls to the top of the discharging plate 36.

[0042] Further, as shown in Figure 5 The inner cavity of the water tank 4 is rotatably installed with two second conveying rollers 41, and the outer surfaces of the two second conveying rollers 41 are jointly installed with a conveying belt 42, and the outer surface of the conveying belt 42 is provided with a plurality of water permeable holes.

[0043] One side of one of the second conveying rollers 41 and one side of the first conveying roller 2 are fixedly installed with a belt pulley 43, and the two belt pulleys 43 are driven by a belt 44.

[0044] In use, the aluminum alloy ingot falls to the top of the conveying belt 42 after buffering through the blanking plate 36, and the first conveying roller 2 rotates with the belt pulley 43 driven by the belt 44, and the belt pulley 43 connected with the second conveying roller 41 rotates with the second conveying roller 41, and the second conveying roller 41 drives the conveying belt 42 to rotate when rotating, and the conveying belt 42 moves with the aluminum alloy ingot on the top of the conveying belt 42, realizing the transfer of the aluminum alloy ingot.

[0045] Further, as shown in Figure 6 The water pump 5 is fixedly installed on one side of the water tank 4, penetrates into the inner cavity of the water tank 4 on one side of the water pump 5, and the first water pipe 51 is fixedly connected on one side of the water pump 5.

[0046] The top cover 501 is fixedly installed on the top of the water tank 4, the connecting box 52 is fixedly installed on the top of the top cover 501, four second water pipes 53 are fixedly installed on the bottom of the connecting box 52, and the spray head 54 is fixedly installed on the bottom of the second water pipe 53.

[0047] In use, the water in the inner cavity of the water tank 4 is pumped out to the inner cavity of the first water pipe 51 by the water pump 5, and then enters the inner cavity of the connecting box 52, and the inner cavity of the connecting box 52 is provided with a valve, and when the aluminum alloy ingot on the top of the conveying belt 42 is cooled, the valve is opened, water is discharged from the inner cavity of the connecting box 52, and is sprayed to the surface of the aluminum alloy ingot through the second water pipe 53 and the spray head 54, realizing the cooling of the aluminum alloy ingot, and the process of pumping the water in the inner cavity of the water tank 4 to the connecting box 52 and making the water flow through the first water pipe 51 can increase the flow time of the water, achieving the purpose of naturally cooling the water.

[0048] Working principle: when the present application is used, first, the aluminum water is added to the mold 22 through the feeding pipe 11, and after the aluminum water is added, the first conveying roller 2 is driven to rotate by the output shaft of the first motor 24, the conveying belt 21 is rotated with the first conveying roller 2, the conveying belt 21 further moves the mold 22 in the inner cavity of the mounting frame 1, the feeding pipe 11 successively adds aluminum water to the inner cavity of the mold 22, and the already added aluminum water will form an aluminum alloy ingot in the form of condensation during the movement, and when the aluminum alloy ingot moves to the vicinity of the limiting rod 23, it will be separated from the mold 22, at this time, the aluminum alloy ingot on one side contacts the limiting rod 23, and the limiting rod 23 is used to limit the aluminum alloy ingot, and when the aluminum alloy ingot is separated from the limiting rod 23, the aluminum alloy ingot will fall on the top of the blanking plate 36, the second disc 33 is rotated with the output shaft of the second motor 34, and the blanking plate 36 is driven to move up and down by the first connecting rod 32, which can shake the aluminum alloy ingot on the top of the blanking plate 36 to the top of the conveying belt 42, and the blanking plate 36 can avoid the aluminum alloy ingot from directly falling on the top of the conveying belt 42, causing damage to the conveying belt 42.

[0049] The first motor 24 drives the second conveying roller 41 to rotate through the transmission of the belt 44, and the second conveying roller 41 drives the conveying belt 42 to rotate to drive the aluminum alloy ingot. The water in the inner cavity of the water tank 4 is pumped out by the water pump 5, sprayed to the surface of the aluminum alloy ingot through the connecting box 52 and the spray head 54, and further cooled. Then the aluminum alloy ingot falls to the top of the roller 6, and the rollers 6 are inclined. Due to the gravity of the aluminum alloy ingot, the aluminum alloy ingot slowly slides on the top of the roller 6. The air pipe 62 is heated by the fan 61, and the hot air is blown to the aluminum alloy ingot to dry the aluminum alloy ingot.
