[0030] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0031] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example

[0033] Please see Figure 1-3As shown in the figure, this embodiment discloses an aluminum molten metal transfer mechanism for aluminum ingot casting, including an upper cylinder 1. A groove 10 is formed on one end face of the upper cylinder 1, and the other end face faces the outlet for discharging the aluminum molten metal. The upper cylinder 1 is fixedly installed at the aluminum molten metal outlet via a detachable connection such as a threaded connection on its outer wall. A lifting mechanism 3 is installed inside the upper cylinder 1 within its groove 10. The lifting mechanism 3 can move back and forth along the central axis of the upper cylinder 1 within the groove 10. A lower cylinder 2 is slidably connected to the bottom of the upper cylinder 1. The lower cylinder 2 is slidably connected to the upper cylinder 1 via the groove 10, and the end face of the lower cylinder 2 within the groove 10 of the upper cylinder 1 is connected to the lifting end of the lifting mechanism 3. This allows the lower cylinder 2 to move back and forth within the groove 10 of the upper cylinder 1 by operating the lifting mechanism 3. This not only prevents splashing of the aluminum molten metal during transport but also allows for height adjustment according to different scenarios, improving adaptability.

[0034] The aforementioned lifting mechanism 3 includes a fixed plate 30, a motor 31, a lead screw 32, and a lead screw nut 33. The fixed plate 30 is disposed on the inner wall of the upper cylinder 1 located inside the slide groove 10. The motor 31 is disposed on the end face of the fixed plate 30 facing the lower cylinder 2, and the lead screw 32 is disposed at the output end of the motor 31, meaning that the motor 31 can drive the lead screw 32 to rotate when it runs. The lead screw nut 33 is disposed on the end face of the lower cylinder 2 located inside the slide groove 10 of the upper cylinder 1 and facing the upper cylinder 1. The lead screw 32 and the lead screw nut 33 are threadedly connected. When the motor 31 runs, the motor 31 drives the lead screw 32 to rotate. The threaded connection between the lead screw 32 and the lead screw nut 33 causes the lead screw nut 33 to move along the central axis of the lead screw 32, thereby driving the lower cylinder 2 to move inside the slide groove 10 of the upper cylinder 1 along the central axis of the upper cylinder 1. This allows the lower cylinder 2 to be adjusted in height within the slide groove 10 of the upper cylinder 1 according to different working scenarios, improving adaptability.

[0035] A collection box 4 is provided on the outer wall of the lower cylinder 2. A negative pressure suction device 5 is provided on the top of the collection box 4. The negative pressure suction device 5 can form a negative pressure inside the collection box 4, so that the collection box 4 can be used to collect the aluminum liquid splashed from the bottom of the lower cylinder 2. Specifically, an outlet 21 connected to the liquid channel 20 is opened on the outer wall of the lower cylinder 2, and an inlet 40 connected to the outlet 21 is opened on the side wall of the collection box 4. When the aluminum liquid flows into the mold, it can be blocked by the upper cylinder 1 and the lower cylinder 2, that is, to prevent the working environment outside the mold from being affected by the splashing of aluminum liquid when it falls into the mold. Furthermore, when molten aluminum splashes, it adheres to the inner wall surface of the upper cylinder 1 and / or the lower cylinder 2. Under the influence of gravity, the molten aluminum flows from the inner wall surface of the upper cylinder 1 / lower cylinder 2 toward the bottom of the lower cylinder 2. When the adhered molten aluminum flows to the liquid channel 20 opening at the bottom of the lower cylinder 2, the presence of the negative pressure suction device 5 creates a negative pressure suction effect inside the liquid channel 20, which draws the molten aluminum passing through the opening of the liquid channel 20 into the liquid channel 20 and collects it in the collection box 4.

[0036] Furthermore, multiple baffles are installed inside the liquid channel 20 in the lower cylinder 2, with gaps between adjacent baffles. Each baffle is inclined to the inner wall of the lower cylinder 2 within the liquid channel 20. Specifically, the inclination direction of each baffle is towards the upper cylinder 1. When the negative pressure suction device 5 creates a negative pressure inside the collection box 4, the molten aluminum flowing inside the upper cylinder 1 and lower cylinder 2 can be attracted by the negative pressure created in the collection box 4 when passing through the opening of the liquid channel 20 in the lower cylinder 2, causing the molten aluminum to enter the liquid channel 20. When the molten aluminum enters the liquid channel 20, it will come into contact with the multiple baffles in the liquid channel 20 in sequence. Since each baffle is inclined towards the upper cylinder 1, and after a negative pressure is created in the collection box 4, each baffle is also inclined towards the direction of liquid flow. The inclined baffles can slow down the speed of the molten aluminum entering the liquid channel 20, and finally enter the interior of the collection box 4. It should be noted here that among the multiple baffles, the end of the baffle near the liquid inlet 40 of the collection tank 4 facing the upper cylinder 1 faces the liquid outlet 21 of the lower cylinder 2. That is, when the aluminum liquid passes through the last baffle, it will slide off the baffle and directly enter the collection tank 4 through the liquid outlet 21 of the lower cylinder 2 for collection, making the process of aluminum liquid entering the collection tank 4 smoother.

[0037] The bottom outer surface of the lower cylinder 2 is an arc surface, that is, the bottom surface of the lower cylinder 2 near the liquid channel 20 is set as an arc surface. When the aluminum liquid splashes and adheres to the inner wall of the upper cylinder 1 and / or the lower cylinder 2, after the aluminum liquid flows to the liquid channel 20 of the lower cylinder 2, it can flow along the arc surface of the bottom outer surface of the lower cylinder 2 to the liquid channel 20 for collection, which improves the convenience of collecting aluminum liquid.

[0038] A gas storage tank 6 is installed on the top of the aforementioned collection tank 4. The gas storage tank 6 is filled with inert gas, and an air pump 7 is also installed on the top of the collection tank 4. The air pump 7 is connected to the gas storage tank 6 via a pipe. Specifically, after the molten aluminum enters the collection tank 4 through the liquid channel 20, the molten aluminum inside the collection tank 4 can be recycled after a certain period of storage. During the storage of the molten aluminum, the air pump 7 pumps the inert gas from the gas storage tank 6 into the collection tank 4, gradually reducing the air inside the collection tank 4 and preventing the air inside the collection tank 4 from affecting the storage of the molten aluminum. It is worth noting that because the air pump 7 introduces inert gas into the collection tank 4, the air pressure inside the collection tank 4 will gradually increase. Therefore, it is necessary to open an exhaust port on the side wall of the collection tank 4 to discharge the air inside the collection tank 4 and prevent the pressure inside the collection tank 4 from becoming too high.

[0039] A collecting ring 8 is provided on the end face of the lower cylinder 2 away from the upper cylinder 1. A collecting port 80 is formed on the inner wall of the collecting ring 8, and a transition cavity is formed inside the collecting ring 8. The transition cavity is connected to the collecting port 80 and the liquid channel 20, respectively. That is, the collecting ring 8 is used to fill the gap between the lower cylinder 2 and the mold. For the aluminum liquid splashed onto the inner wall of the upper cylinder 1 and / or the lower cylinder 2, after flowing to the collecting port 80 of the collecting ring 8, it can enter the transition cavity through the collecting port 80, then enter the liquid channel 20 through the transition cavity, and finally enter the collecting tank 4 for collection. In order to avoid the collecting ring 8 affecting the entry of aluminum liquid into the mold, the inner diameter of the collecting ring 8 in this embodiment is smaller than the inner diameter of the lower cylinder 2.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
