[0011] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0012] Referring to the accompanying drawings, a direct printing device for annular crucibles includes a printable part 1 and a vacuum chamber 2. A support base 3 is fixedly installed inside the vacuum chamber 2, and the printable part 1 is installed on top of the support base 3. Crucibles 4 are fixedly arranged in an array on the top of the vacuum chamber 2, and nozzles 5 are fixedly installed at the bottom of the crucibles 4. The nozzles 5 pass through the top of the vacuum chamber 2 and are located directly above the vacuum chamber 2.

[0013] The top of the support base 3 is fixedly provided with a synchronous lifter 6, the top of the synchronous lifter 6 is symmetrically provided with a bracket 7, the top of the bracket 7 is fixedly provided with a support plate 8, and the center of the top of the support plate 8 is fixedly provided with a rotary support bearing 9.

[0014] A drive motor 10 is fixedly installed at the bottom of the support plate 8. A gear is fixedly installed at the output end of the drive motor 10. The gear meshes with the outer ring of the rotary support bearing 9. A base plate 11 is fixedly installed at the top of the outer ring of the rotary support bearing 9. This structural design drives the outer ring of the rotary support bearing 9 to rotate, thereby driving the base plate 11 to rotate. The inner ring of the rotary support bearing 9 is fixedly connected to the top of the support plate 8. The printed part 1 is installed on the top of the base plate 11.

[0015] The vacuum chamber 2 is fixedly installed at the four corners of the top, the crucible 4 is fixedly installed inside the outer shell 12, the outer shell 12 is provided with a heat source to provide heat for melting, and the bottom of the crucible 4 is fixedly installed with a liquid delivery pipe 13, the other end of which is fixedly connected to the nozzle 5.

[0016] Each of the outer shells 12 is symmetrically fixedly provided with a rotating jet 14 on its top. This structural design provides a function for degassing and purifying the molten aluminum, so that the molten aluminum reaching the nozzle is purified. Each of the outer shells 12 is fixedly provided with a control switch 15 on its top. The control switch 15 is coaxially arranged with the infusion pipe 13. This structural design can control the on / off of the jet from the nozzle 5. A heating tube is fixedly provided on the nozzle 5 to provide a heat source for the nozzle 5.

[0017] When using this device, the metal raw material to be printed (such as aluminum alloy ingot) is added into the crucible 4 to ensure that the amount of raw material matches the design volume of the printed part 1. Before printing begins, the entire crucible is hoisted into position, the door of the vacuum chamber 2 is closed, the vacuum unit is started, and the air is evacuated to the vacuum level required by the process. The vacuum level is maintained to isolate the air. The rotating jet 14 at the top of each outer shell 12 is started to spray inert gas into the molten metal. The rotating agitation breaks the air bubbles in the molten metal and adsorbs impurities, thus achieving degassing and purification. The purified molten metal is transported to the nozzle 5 through the liquid delivery pipe 13. The heating tube on the nozzle 5 continuously heats the molten metal to prevent it from solidifying inside the nozzle. Start the synchronous lifter 6, adjust the height of the support plate 8 so that the base plate 11 is in the initial printing position, start the drive motor 10, and its output gear meshes with the outer ring of the rotary support bearing 9, driving the base plate 11 to rotate at a set speed; trigger the control switch 15, and the nozzle 5 sprays molten metal onto the surface of the rotating base plate 11, forming the first layer of annular trajectory; the drive motor 10 outputs a stable speed, driving the base plate 11 to rotate continuously, ensuring the continuity of the annular trajectory; the synchronous lifter 6 gradually adjusts the height of the base plate according to the preset layer thickness (e.g., each layer decreases by 0.2mm), realizing the layer-by-layer accumulation of molten metal; the control switch 15 precisely controls the jet flow of the nozzle 5, and in conjunction with the rotation / lifting motion, prints the inner and outer contours, bosses, and other features of the annular part; Once the printed part 1 reaches the designed size, turn off the control switch 15 to stop the nozzle from spraying; the drive motor 10 and the synchronous lift 6 stop, and the part is removed and processed after the molten metal has completely solidified.
