[0015] Compared with the prior art, the advantages and positive effects of the present invention are: (1) The aluminum rods produced by the existing casting machine have many defects, while the present invention has a plurality of arc grooves 2 opened on the graphite ring between the upper part and the lower part of the crystallizer, the adjacent arc grooves 2 are connected through the arc groove 3, and the outer sides of the adjacent arc grooves 2 are connected through the arc groove 1, and the lubricating oil enters the arc groove 1, the arc groove 2 and the arc groove 3 through the connecting piece and the arc groove 4. Since the arc groove 2 has multiple branches, the time of the lubricating oil in the graphite ring can be extended, and more lubricating oil can be retained in the graphite ring, so that the graphite ring can better absorb the lubricating oil, and an oil film is formed inside the graphite ring, which can improve the production quality of the aluminum rod; (2) A plurality of inclined through holes are provided on the outer periphery of the lower part of the crystallizer, and a second oil pipe branch is installed and connected to the outer sides of the plurality of inclined through holes. The lubricating oil can enter the inner side of the lower part of the crystallizer through the second oil pipe branch, so that an oil film is formed on the inner side of the lower part of the crystallizer, which is conducive to the production of smooth aluminum bars and improves the quality of the aluminum bars. (3) An air jet device is installed above the support plate. The air jet device drives the lifting plate to move up and down through cylinder 1, and cylinder 2 drives the cross tube to move up and down, so that the nozzle is located above the aluminum liquid. The nozzle sprays argon gas into the aluminum liquid. The argon gas generates bubbles in the aluminum liquid. As the bubbles rise, the hydrogen and inclusions in the aluminum liquid are brought out to the surface of the aluminum liquid, reducing the inclusions in the aluminum rod. Later, only the position of the inclusions at the top of the aluminum rod needs to be cut off; (4) The existing casting machine adopts the method of unloading by the ingot head and only provides one-time cooling. However, the present invention is provided with a cooling ring on the outer periphery of the lower part of the crystallizer, cooling water is introduced into the cooling ring, and a unloading tray is provided under the cooling ring. The unloading tray is driven by a servo motor to unload the material, which can ensure the stability of the aluminum rod during the unloading process. A secondary cooling device is installed in the unloading box, which drives the upper and lower fish holes of the driving motor through the servo motor, and the driving motor drives the fan shaft to rotate, so that the aluminum rod is cooled for the second time during the unloading process, which is beneficial to the overall cooling of the aluminum rod, thereby improving the production quality of the aluminum rod; (5) A swing ring is set above the crystallizer. The cylinder 4 pushes the moving part to move in the shell. The swing ring can move back and forth along the direction of the cylinder 4, and the produced aluminum rod can be separated from the swing ring. Due to the effect of argon gas, the inclusions in the aluminum liquid are located on the surface of the aluminum liquid, and the subsequent cutting of this part will not affect the production length of the aluminum rod; (6) The pressing piece is pushed by cylinder 3 to cooperate with fixed shaft 1, and the rotating motor drives the supporting plate to rotate, so as to facilitate taking out the produced aluminum bars in the unloading box.

[0030] In the present invention, the crystallizer is an existing crystallizer.

[0031] In the present invention, the length of the feed trough is smaller than the length of the workbench 1 in the direction of the feed trough.

[0032] In the present invention, the tops of the plurality of baffles 11 and the top of the swing ring 26 are located on the same horizontal line.

[0043] The operation flow of the present invention is as follows: Step 1: Before processing the aluminum rod, the staff needs to apply lubricating oil to the inside of the swing ring 26, and start pumps 2 and 3 in advance. Pump 2 draws the lubricating oil in the oil tank 33 into the connecting piece 39, and enters the arc groove 4 55 through the connecting piece 39. The lubricating oil flows into the arc groove 1 52, the arc groove 3 54 and the arc groove 2 53. Due to the structure of the arc groove 1 52, the arc groove 3 54 and the arc groove 2 53, the lubricating oil can be more located in the graphite ring 31, so that an oil film is generated inside the graphite ring 31 (that is, the characteristic of the graphite ring 31). Pump 3 draws the lubricating oil in the oil tank 33 into the inclined through hole, and the lubricating oil flows to the inside of the lower part 30 of the crystallizer through the inclined through hole. After a period of time, pumps 2 and 3 are turned off.

[0044] Step 2: Turn on pump 1 and cylinder 5 27. Pump 1 extracts the aluminum liquid in the aluminum liquid box 12 into the feed trough. Cylinder 5 27 drives the arc baffle 29 to move upward. When it moves a certain distance, turn off cylinder 5 27. The aluminum liquid enters the crystallizer through the feed trough and the connection position between the feed trough and the crystallizer for crystallization. When the aluminum liquid in the crystallizer is located in the swing ring 26, turn off pump 1 and turn on cylinder 5 27. Cylinder 5 27 drives the arc baffle 29 to move downward. The arc baffle 29 returns to the initial position. Turn off cylinder 5 27 and turn on cylinder 13. , cylinder 1 3 drives the lifting plate 4 to move downward. After moving a certain distance, cylinder 1 3 is closed and cylinder 2 6 is opened. Cylinder 2 6 drives the cross tube 7 to move downward until it moves above the aluminum liquid. Cylinder 2 6 is closed and pump 4 is opened. Pump 4 extracts argon from the argon storage box 9 and enters the nozzle under the cross tube 7 through the argon pipe 8. The nozzle sprays argon into the aluminum liquid. After a period of time, pump 4 is closed and argon is sprayed into the aluminum liquid. Argon generates bubbles in the aluminum liquid. As the bubbles rise, hydrogen and inclusions in the aluminum liquid are brought out to the surface of the aluminum liquid.

[0045] Step 3: Turn on pump 5, which pumps the cooling water in the water tank 37 into the cooling ring 35 until the cavity of the cooling ring 35 is filled with cooling water, and then turn off pump 5.

[0046] Step 4: After a period of time, the aluminum liquid generates aluminum rods at the position of the lower part 30 of the crystallizer (that is, the aluminum rods are located at the position of the cooling ring 35, and the aluminum liquid is above the aluminum rods). The servo motor 1 44, the servo motor 2 48 and the drive motor 50 are turned on. The servo motor 1 44 drives the ball screw 1 to rotate, so that the slider 1 43 drives the unloading tray 46 to move downward, and the unloading tray 46 drives the generated aluminum rods to move downward. The servo motor 2 48 drives the ball screw 2 to rotate, so that the drive motor 50 moves downward along the guide rail 47. The drive motor 50 drives the fan shaft to rotate, and the generated aluminum rods are cooled for a second time until the upper part of the produced aluminum rods is located a distance above the lower part 30 of the crystallizer, and the servo motor 1 44, the servo motor 2 48 and the drive motor 50 are turned off.

[0047] Step 5: Repeat steps 2 and 4 in sequence until the unloading tray 46 is located at the lowest position of the guide rail 42. After a period of time, until the aluminum liquid in the swing ring 26 solidifies to form an aluminum rod, open cylinder 4 22, and cylinder 4 22 pushes the moving part to move in the shell 23, so that the swing part 25 drives the swing ring 26 to swing back and forth along the direction in which the cylinder 4 22 pushes the moving part, so that the aluminum rod and the swing ring 26 are separated, close cylinder 4 22, open cylinder 3 19, and cylinder 3 19 drives the pressing part 20 to move toward the direction close to cylinder 3 19. After moving to the set position, close cylinder 3 19, and start the rotating motor 13. The rotating motor 13 drives the support plate 2 to rotate. After the support plate 2 rotates 90 degrees, turn off the rotating motor 13, turn on the servo motor 44, so that the unloading tray 46 drives the entire generated aluminum rod to move upward. After moving to the set position, turn off the servo motor 44, and the staff takes out the aluminum rod by crane or manually.

[0048] In the present invention, the cooling water in the cooling ring 35 can be replaced according to the on-site conditions. Pump five is turned on, and pump five draws the cooling water in the cooling ring 35 into the water tank 37.
