Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy manufacturing technology, and more specifically, to a device for melting, casting and forming recycled aluminum ingots. Background Technology

[0002] When manufacturing aluminum alloys, the mixed metal raw materials need to be heated to a molten state. The molten metal raw materials are then poured into a forming mold, and the cooled metal is removed from the mold for subsequent processing and polishing.

[0003] When casting molten aluminum alloy raw materials, the raw materials are usually directly injected into the mold through an extrusion mechanism. Impurities and particles may be present in the raw materials, which will affect the effect after molding. During casting, the raw materials are prone to uneven mixing, resulting in poor quality and low strength of the molded aluminum alloy.

[0004] A search revealed a Chinese patent with publication number CN213826979U that discloses an automatic casting device for aluminum alloy melting. This utility model uses the reciprocating extension of the first electric telescopic rod of the extrusion mechanism to drive the extrusion plate to repeatedly extrude the filter bag. The raw material inside the filter bag is squeezed, resulting in better filtration. By setting up a stirring mechanism, the second motor of the stirring mechanism drives the stirring paddle to rotate, stirring the raw material, making the aluminum alloy raw material more uniformly mixed and improving the aluminum alloy forming effect.

[0005] However, in actual use, during the quantitative feeding of the raw material after the recycled aluminum is melted, the temperature of the recycled aluminum liquid will decrease during the stirring and conveying process because the aluminum liquid needs a certain amount of time to filter and flow. This will increase the viscosity of the recycled aluminum liquid and prevent it from filling the pores of the mold well. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for melting, casting and forming recycled aluminum ingots to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A recycled aluminum ingot smelting and casting forming device includes an outer cylinder, a support fixedly connected to the outer side of the outer cylinder, multiple mold bodies arranged on the outer side of the support, and an auxiliary output mechanism at the bottom of the outer cylinder. The auxiliary output mechanism includes an outer ring, a base frame fixedly connected to the inner side of the outer ring, multiple discharge ports on the inner side of the outer ring, a cavity on the inner side of the base frame, a heater fixedly connected to the inner side of the outer cylinder, a heater fixedly connected to the inner side of the base frame, and a servo motor fixedly connected to the bottom of the base frame. A rotating shaft is fixedly connected to the output end. Two sealing rings are fixedly connected to the outer side of the rotating shaft. The outer side of the sealing rings is rotatably connected to the inner side of the base frame. One end of the rotating shaft passes through the inner side of the base frame and extends into the inner cavity of the outer cylinder. A rotating seat is fixedly connected to the top of the rotating shaft. Multiple arc-shaped sweeping rods are fixedly connected to the outer side of the rotating seat. Multiple feeding hoppers are fixedly connected to the outer side of the outer ring. A cylinder is fixedly connected to the outer side of the outer ring. A gate is fixedly connected to one end of the cylinder. The outer side of the gate is slidably connected to the inner side of the discharge port. An auxiliary cleaning mechanism is provided on the outer side of the outer cylinder.

[0009] By adopting the above technical solution: heater one and heater two are used to heat the inside of the outer cylinder and the base frame, so that the temperature of the recycled aluminum liquid is kept stable when it comes into contact with the outer cylinder and the base frame, so that the recycled aluminum liquid can have good fluidity, and the recycled aluminum liquid can be continuously output for casting by the rotating seat and the arc-shaped sweeping rod.

[0010] As a further description of the above technical solution: the auxiliary cleaning mechanism includes a cover plate, the bottom of which is snapped into the top of the outer cylinder. Multiple screws are threadedly connected to the outer side of the cover plate and the outer cylinder. A feed cylinder is fixedly connected to the top of the cover plate. A second servo motor is fixedly connected to one side of the feed cylinder. A rotating drum is fixedly connected to the output end of the second servo motor. The outer side of the rotating drum is rotatably connected to the inner side of the feed cylinder. Multiple grooves are provided on the outer side of the rotating drum. A feed hopper is fixedly connected to the top of the feed cylinder. A funnel filter screen is slidably connected to the inner side of the outer cylinder. Multiple locking blocks are fixedly connected to the outer side of the funnel filter screen. The outer side of the locking blocks is slidably connected to the inner side of the outer cylinder. Multiple handles are fixedly connected to the inner side of the funnel filter screen.

[0011] By adopting the above technical solution, the funnel filter screen can be removed from the inside of the outer cylinder after casting by sliding between the funnel filter screen and the inner side of the outer cylinder. This facilitates cleaning of the funnel filter screen and ensures that it maintains a good filtration effect.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By setting up an auxiliary output mechanism, compared with the existing technology, the continuous heating of the recycled aluminum liquid by heater one and heater two prevents the temperature of the recycled aluminum liquid from dropping before casting, so that the recycled aluminum liquid has good fluidity and maintains a good viscosity between the recycled aluminum liquids. This allows the recycled aluminum liquid to better fill the gaps inside the mold body during the casting process, improving the qualification rate of the recycled aluminum liquid casting mold. Furthermore, by controlling the opening of different discharge ports, it is possible to cast multiple molds simultaneously, thereby improving the casting efficiency of the casting device.

[0014] By setting up an auxiliary cleaning mechanism, compared with the existing technology, the recycled aluminum molten material can be gathered and passed through the funnel filter screen under the force of gravity to complete the filtration, reducing the amount of cleaning work of the casting system and mold. Furthermore, the detachable cover plate, outer cylinder and funnel filter screen can effectively clean the inside of the casting device. Attached Figure Description

The auxiliary output mechanism includes an outer ring 6, a base frame 7 fixedly connected to the inside of the outer ring 6, multiple discharge ports 27 opened on the inside of the outer ring 6, a cavity 9 opened on the inside of the base frame 7, a heater 8 fixedly connected to the inside of the outer cylinder 1, a heater 10 fixedly connected to the inside of the base frame 7, a servo motor 11 fixedly connected to the bottom of the base frame 7, a rotating shaft 12 fixedly connected to the output end of the servo motor 11, two sealing rings 13 fixedly connected to the outside of the rotating shaft 12, the outer side of the sealing rings 13 being rotatably connected to the inside of the base frame 7, one end of the rotating shaft 12 penetrating the inside of the base frame 7 and extending into the outer cylinder 1, and a rotating seat 14 fixedly connected to the top of the rotating shaft 12. Multiple arc-shaped sweeping rods 15 are fixedly connected to the outer side of the rotary seat 14, and multiple feeding hoppers 16 are fixedly connected to the outer side of the outer ring 6. A cylinder 17 is fixedly connected to the outer side of the outer ring 6, and a gate 18 is fixedly connected to one end of the cylinder 17. The outer side of the gate 18 is slidably connected to the inner side of the discharge port 27. An auxiliary cleaning mechanism is set on the outer side of the outer cylinder 1. Heater 1 8 and heater 2 10 are used to heat the inside of the outer cylinder 1 and the base frame 7, so that the recycled aluminum raw liquid is kept warm inside the outer cylinder 1 and the base frame 7. Then, servo motor 11 drives the rotating shaft 12 to drive the rotary seat 14 and the arc-shaped sweeping rods 15, so that the multiple arc-shaped sweeping rods 15 can output the recycled aluminum raw liquid from the inside of the multiple discharge ports 27. According to production needs, one or more cylinders 17 can be activated to pull the gate 18 to open the discharge port 27, thereby improving the production efficiency of the mold casting.

[0024] Reference Figure 1 , Figure 3 and Figure 4As shown, the auxiliary cleaning mechanism includes a cover plate 4, the bottom of which is snapped into the top of the outer cylinder 1. Multiple screws 5 are threadedly connected to the outer sides of the cover plate 4 and the outer cylinder 1. A feed cylinder 19 is fixedly connected to the top of the cover plate 4. A servo motor 20 is fixedly connected to one side of the feed cylinder 19. A rotating drum 21 is fixedly connected to the output end of the servo motor 20. The outer side of the rotating drum 21 is rotatably connected to the inner side of the feed cylinder 19. Multiple grooves 22 are provided on the outer side of the rotating drum 21. A feed hopper 23 is fixedly connected to the top of the feed cylinder 19. A funnel filter screen 24 is slidably connected to the inner side of the outer cylinder 1. Multiple locking blocks 25 are fixedly connected to the outer side of the funnel filter screen 24. The outer side of the locking block 25 is slidably connected to the inner side of the outer cylinder 1. Multiple handles 26 are fixedly connected to the inner side of the funnel filter screen 24. The servo motor 20 drives the rotating drum 21 and the groove 22 to deliver the recycled aluminum raw liquid in segments. The funnel filter screen 24 is used to filter the recycled aluminum raw liquid. The funnel shape of the funnel filter screen 24 slows down the fall of the recycled aluminum raw liquid, avoiding excessive scouring between the recycled aluminum raw liquid and the interior of the outer cylinder 1 and the base frame 7. Afterwards, the outer cylinder 1 and the cover plate 4 can be opened, and the funnel filter screen 24 and the locking block 25 can be removed through the handles 26 to clean the surface of the funnel filter screen 24.

[0025] The working principle of this utility model is as follows: When casting recycled aluminum molten metal, the recycled aluminum molten metal is first poured into the feed hopper 23. Then, servo motor 20 drives the rotating drum 21 to transport the recycled aluminum molten metal in segments and in a quantitative manner through multiple grooves 22. The recycled aluminum molten metal then falls downward through the grooves 22, allowing it to fall into the funnel filter screen 24. The larger impurities mixed in with the recycled aluminum molten metal are filtered through the holes on the surface of the funnel filter screen 24. Afterward, the recycled aluminum molten metal continues to fall into the tank body composed of the outer cylinder 1, outer ring 6, and base frame 7. After a certain amount of recycled aluminum molten metal has accumulated, heater 8 and heater 10 are activated to heat the interior of the outer cylinder 1 and base frame 7. Heating is performed to maintain sufficient temperature and fluidity of the recycled aluminum liquid after it has accumulated. Then, multiple mold bodies 3 are placed under the corresponding hoppers 16. Then, multiple cylinders 17 are activated to drive the gate 18 to slide inside the outlet 27. Then, servo motor 11 drives the rotating shaft 12 to drive the rotating seat 14 and multiple arc-shaped sweeping rods 15. This allows the multiple rotating seats 14 to sweep the recycled aluminum liquid accumulated on the top of the base frame 7. This allows the recycled aluminum liquid to be transported from the inside of the outer cylinder 1 and the base frame 7 to the multiple outlets 27. The recycled aluminum liquid inside the outer cylinder 1 can pass through the outlet 27 and then flow down through the hopper 16 into the inside of the mold body 3.

[0026] After the pouring is completed, the screws 5 can be separated from the outer cylinder 1 and the cover plate 4. Then, the cover plate 4 is removed from the top of the outer cylinder 1. The workers then use the handle 26 to remove the funnel filter screen 24 from the inside of the outer cylinder 1, clean the larger impurities filtered out from the inside of the handle 26, and finally re-insert the funnel filter screen 24 into the inside of the outer cylinder 1 through the multiple clips 25 for subsequent use.
