Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, and in particular to an automatic casting device for aluminum ingots. Background Technology

[0002] Aluminum ingots, as the basic material for aluminum processing, are widely used in various industrial production fields such as automobiles, aerospace, machinery manufacturing, and power. Their production efficiency and quality directly affect the development of downstream industries. In the aluminum ingot casting process, molten aluminum comes into direct contact with air and is easily oxidized. At the same time, it is difficult to control the casting speed and the uniformity of the quality of molten aluminum poured during casting by manual operation, which affects the production quality of aluminum ingots. Therefore, aluminum ingot casting has gradually developed into a fully automated operation.

[0003] In existing automatic aluminum ingot casting devices, a molten aluminum distributor with a guide pipe vertically connected to the circumference side is usually used to evenly distribute the molten aluminum in the guide channel. The guide pipe is pushed by the mold during transmission, or the molten aluminum distributor is directly driven by a motor to rotate synchronously with the mold, automatically injecting the molten aluminum into the mold in equal amounts. The molten aluminum is discharged from the mold at a relatively fast flow rate through the vertically connected guide pipe, which can easily cause impact on the inner side of the mold, resulting in open flow, increasing the risk of oxidation and burr defects. In addition, the relative position of the guide pipe and the conveyor belt is unstable, resulting in uneven casting quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an automatic aluminum ingot casting device. The device drives a conveyor chain to transport the mold placed on the pallet through a rotating device. At the same time, the conveyor chain drives the transmission structure to rotate. The transmission structure drives the molten metal distributor connected to the rotating shaft to rotate, so that the molten aluminum in the smelting furnace is automatically and evenly poured into the mold, and the casting operation is more precise. At the same time, the liquid discharge from the inclined guide pipe is more gentle, which improves the efficiency and quality of aluminum ingot casting.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic aluminum ingot casting device includes a shell, a melting furnace, a guide channel, a frame, and a conveyor chain. The melting furnace is rotatably connected inside the shell. The guide channel is vertically connected to the side of the shell directly below the outlet of the melting furnace. The frame is placed beside the guide channel. The conveyor chain is connected to the top inner side of the frame via a rotating shaft. A push-pull device is rotatably connected to the top surface of the base of the shell. The output end of the push-pull device is rotatably connected to the melting furnace. A drive device and a rotating device are connected to one side of the frame. The drive device is connected to the input end of the rotating device, and the output end of the rotating device is connected to the rotating shaft of the conveyor chain. Equivalently spaced parallel support plates are connected to the top of the conveyor chain. A mold is movably connected to the top surface of the support plates. A distributor is rotatably connected to the end of the guide channel. The distributor's output... A rotating shaft is vertically connected to the center of the side where the outlet is located. A bracket is connected to the top of the frame. The rotating shaft is rotatably connected to the top of the bracket directly opposite. The end of the rotating shaft is connected to the transmission chain through a transmission structure, which includes a main sprocket, a secondary sprocket, and a transmission chain. The shaft of the main sprocket is parallel to the rotating shaft and is rotatably connected to the top of the bracket next to the rotating shaft. The main sprocket meshes with the transmission chain. The shafts of the main sprocket and the rotating shaft are connected to the secondary sprockets in opposite positions at the parts extending out of the top surface of the frame. The two secondary sprockets are connected to each other through a transmission chain. A fan is connected to the top of the bracket in the middle section of the frame and near the end of the transmission chain. The fan's air outlet faces the starting direction of the transmission and the top surface of the tray. The fan is deflected 15 degrees relative to the vertical direction.

[0007] Furthermore, the push-pull device is a hydraulic rod, the drive device is a motor, the rotating device is a reducer, the rotating shaft of the drive device is connected to the input end of the rotating device, and the rotating shaft of the output end of the rotating device is connected to the input shaft of the transmission chain.

[0008] Furthermore, the distributor is a liquid metal distributor, including a liquid storage chamber and a guide pipe. The inlet of the liquid storage chamber is rotatably connected to the end of the guide groove, and the guide pipe is equidistantly distributed and connected to the end of the liquid storage chamber.

[0009] Furthermore, the central axis of the guide tube is positioned parallel to the central axis of the liquid storage chamber, but is deflected 30 degrees in the opposite direction to the central axis of the liquid storage chamber.

[0010] Furthermore, the vertical distance between the liquid storage cavity and the top surface of the tray is greater than the height of the mold, and the minimum vertical distance between the guide pipe and the bottom surface of the mold that is vertically opposite is less than the internal height of the mold.

[0011] Furthermore, the rotation axis is parallel to the top surface of the tray and perpendicular to the transmission chain in the horizontal direction.

[0012] Compared with the prior art, this utility model has the following obvious advantages:

[0013] I. In this utility model, a molten metal distributor is rotatably connected to the end of the guide channel. The central axis of the guide tube of the molten metal distributor is tilted and deflected 30 degrees in the opposite direction to the central axis of the liquid storage cavity at a position parallel to the central axis of the liquid storage cavity. After the molten aluminum flows out of the liquid storage cavity through the guide tube, it enters the mold more smoothly, which makes it less likely to produce open flow, which would lead to oxidation risk and the generation of flash or burrs.

[0014] II. In this utility model, a rotating shaft is vertically connected to the center of the side where the output end of the molten metal distributor is located. The rotating shaft is connected to the transmission chain through a transmission structure. During the transmission process, the transmission chain drives the transmission structure to rotate. The transmission structure drives the rotating shaft and the molten metal distributor connected to the rotating shaft to rotate, so that the molten metal distributor can rotate synchronously with the mold in the transmission process. The molten aluminum can be evenly distributed to each mold, ensuring the quality of aluminum ingot casting.

[0015] Third, this utility model has fans connected to the top of the frame in the middle section and near the end of the transmission through brackets. The fans are set at an angle so that the air outlet faces the top surface of the transmission start end and the tray. The fans blow air to cool the mold after casting during transmission, which accelerates the cooling and forming of aluminum ingots in the mold. Attached Figure Description

The guide pipe 502 is evenly distributed around the end of the liquid storage chamber 501. The central axis of the guide pipe 502 is parallel to the central axis of the liquid storage chamber 501 and deflected 30 degrees in the opposite direction to the central axis of the liquid storage chamber 501. A rotating shaft 10 is vertically connected to the center of the side where the output end of the distributor 5 is located.

[0024] The transmission chain 8 is connected to the top inner side of the frame 6 via a rotating shaft. The drive device 12 is a motor, and the rotating device 13 is a reducer, both connected to one side of the frame 6. The rotating shaft of the drive device 12 is connected to the input end of the rotating device 13, and the rotating shaft of the output end of the rotating device 13 is connected to the input shaft of the transmission chain 8. The top of the transmission chain 8 is equidistantly connected to a support plate 9, and the mold 15 is movably connected to the top surface of the support plate 9. The vertical distance between the liquid storage chamber 501 of the distributor 5 and the top surface of the support plate 9 is greater than the height of the mold 15, and the minimum vertical distance between the guide pipe 502 and the bottom surface of the vertically opposite mold 15 is less than the internal height of the mold 15. The top of the frame 6 is connected to a parallel bracket 7, and the rotating shaft 10 is rotatably connected to the top of the opposite bracket 7. The rotating shaft 10 is parallel to the top surface of the support plate 9 and perpendicular to the transmission chain 8 in the horizontal direction.

[0025] The end of the rotating shaft 10 is connected to the transmission chain 8 through the transmission structure 11. The transmission structure 11 includes a main sprocket, a secondary sprocket, and a transmission chain. The shaft of the main sprocket is parallel to the rotating shaft 10 and is rotatably connected to the top of the bracket 7 next to the rotating shaft 10. The main sprocket meshes with the transmission chain 8. The shaft of the main sprocket and the part of the rotating shaft 10 that extends out of the top surface of the frame are connected to the secondary sprockets in opposite positions. The two secondary sprockets are connected to each other through the transmission chain. The fan 14 is connected to the top of the bracket 7 connected to the frame 6 near the end of the transmission chain 8 in the middle section of the transmission. The fan 14 is set to be deflected 15 degrees relative to the vertical direction, and the air outlet of the fan 14 faces the starting direction of the transmission and the top surface of the tray 9.

[0026] The working principle of this utility model is as follows:

[0027] When using this utility model, the operator adds the raw materials to the smelting furnace 3 for smelting and degassing to obtain the molten aluminum required for casting aluminum ingots. The molds 15 for the required production specifications of aluminum ingots are neatly arranged on the top surface of the pallet 9. The operator starts the push-pull device 2 and the drive device 12. The hydraulic rod pushes the telescopic rod to extend, pushing the smelting furnace 3 to tilt in the direction of the guide channel 4. The molten aluminum in the smelting furnace 3 flows into the guide channel 4 from the discharge port connected to the shell 1, and enters the liquid storage chamber 501 of the distributor 5 at the end of the guide channel 4. At the same time, the rotating shaft of the drive device 12 rotates, driving the rotating device 13 to operate. The rotating shaft at the output end of the rotating device 13 drives the input shaft of the transmission chain 8 to rotate, and the transmission chain 8 begins to transmit the pallet 9 connected to the top and the molds 15 placed on the pallet 9.

[0028] In the transmission structure 11, the main sprocket meshing with the transmission chain 8 is driven to rotate by the transmission chain 8. The secondary sprocket connected to the end of the main sprocket's shaft drives the rotating shaft 10 to rotate via the transmission chain. The rotating shaft 10 drives the connected distributor 5 to rotate. During the transmission of the mold 15 and the rotation of the distributor 5, the guide pipe 502 of the distributor 5 corresponds to the mold 15 in sequence. The end of the guide pipe 502 at the bottom rotates into the interior of the mold 15, and the molten aluminum in the storage chamber 501 flows through the guide pipe 502 at the bottom. The molten aluminum flows into the mold 15 directly below. The distance between the guide pipe 502 and the inner side of the mold 15 is small and the flow rate of the molten aluminum is slow, which ensures the casting quality of the aluminum ingot 16. When the molten aluminum level rises to a position higher than the opening of the guide pipe 502, the molten aluminum no longer flows out of the guide pipe 502 after the guide pipe 502 rotates away from the top surface of the mold 15 directly below, thus completing the molten aluminum injection into the mold 15. The mold 15, after the molten aluminum injection is completed, is cooled by the air cooling effect of the fan 14 during the transmission process and solidifies in the mold 15 to form the aluminum ingot 16.

[0029] The operator can change the mold 15 to different specifications and adjust the working speed of the drive device 12 according to the specifications of the aluminum ingot 16 to be cast, thereby changing the speed of the mold 15 transmission and distributor 5 rotation to adapt to the casting requirements of aluminum ingot 16 of different specifications.

They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
