[0002] A 3D printer is a device that creates three-dimensional objects by stacking materials layer by layer. It is widely used in industrial design, medical care, education, architecture, art and other fields.

[0004] Although the above-mentioned application and the prior art can enable the support plate to be moved out of the printer body to facilitate workers to take it out, when the above-mentioned application and the prior art are used to print the gantry casting mold, metal powder will be wasted, thereby gradually increasing the economic cost. After the metal powder is recycled, the oxygen content inside the metal powder will gradually increase with multiple recycling and use. When the metal powder with too high an oxygen content is used in the casting process, bubbles will appear in the gantry casting mold, thereby affecting the molding quality of the gantry casting mold. When the metal powder with too high an oxygen content is subjected to oxygen reduction treatment, the metal powder will come into contact with other objects. Therefore, it is inconvenient to distinguish the treated metal powder from other objects, thereby reducing the efficiency of reuse. Therefore, the present invention proposes a gantry casting mold 3D printing device and method. Summary of the Invention

[0016] (3) Beneficial effects Compared with the prior art, the present invention provides a gantry-type casting mold 3D printing device and method, which has the following beneficial effects: 1.

As the pushing tooth plate moves, the pushing tooth plate is driven to rotate through the pushing gear, so that the rotating rod drives the limiting tooth plate to be gradually stored in the interior of the rotating cylinder through the lifting gear, thereby changing the connection between the rotating cylinder and the storage plate from being clamped to being rotated, and then the driving motor is started again and the solenoid valve of the discharge port is opened. The driving motor drives the rotating rod to rotate through the rotating cylinder, so that the rotating rod drives the differentiation plate to rotate, and then the differentiation plate drives the grinding balls, calcium sheets and metal powder to rotate in different areas, so that the processed metal powder flows into the discharge port from the screening hole, thereby separating the metal powder from other objects, thereby achieving the effect of easy differentiation.

Then, the first cylinder 11 is activated through the control panel 13, so that the first cylinder 11 drives the mold box 112 to move via the first telescopic column 111, and then the mold box 112 drives the printed gantry-type casting mold out of the interior of the operating table 1; For specific embodiment 2, please refer to Figures 1 to 7 According to the gantry-type casting mold 3D printing device provided in the specific embodiment 1, this embodiment provides a further technical solution: The recovery component 2 includes a pushing plate 21 fixedly connected to the bottom of the mold box 112 and an air cylinder 22 fixedly connected to the inside of the operating table 1, one side of the pushing plate 21 is fixedly connected to a pushing rod 211, one end of the pushing rod 211 is fixedly connected to a pushing disk 212, and the pushing disk 212 is slidably connected to the inside of the air cylinder 22.

As the air pressure inside the fixed cylinder 23 continues to increase, the sealing plate 231 moves inside the fixed cylinder 23. During the movement, the sealing plate 231 drives the recovery plate 234 to move through the push rod 232, so that the recovery plate 234 pushes the residual metal powder that has fallen into the operating table 1, so that the residual metal powder enters the inside of the cylinder groove through the recovery groove; For specific example three, please refer to Figures 1 to 12 According to the gantry-type casting mold 3D printing device provided in the second specific embodiment, this embodiment provides a further technical solution: The deoxidation component 3 includes a pull plate 31 fixedly connected to the back of the mold box 112 and a screw rod 32 rotatably connected to the inside of the drum groove. The surface of the screw rod 32 is fixedly connected to a storage wheel 321. The surface of the storage wheel 321 is provided with a pull rope 322. The end of the pull rope 322 away from the storage wheel 321 is fixedly connected to one end of the pull plate 31. The screw rod 32 extends to the interior of the processing box 14.

The surface of the receiving tray 34 is provided with an annular groove 341. A plurality of grinding balls and calcium tablets are arranged inside the receiving tray 34. The top and bottom of the receiving tray 34 are respectively provided with a feed port 342 and a discharge port 343. The surfaces of the feed port 342 and the discharge port 343 are both provided with a solenoid valve 344. The inside of the annular groove 341 is fixedly connected to a plurality of telescopic rods 346. The surfaces of the plurality of telescopic rods 346 are fixedly connected to an extension disk 347. A plurality of screening holes 345 are provided on the extension disk 347 and the inside of the receiving tray 34. The extension disk 347 is slidably connected to the inside of the annular groove 341. It should be noted that the storage tray 34 and the extension tray 347 are arranged obliquely in the processing box 14; When the oxygen content of the recycled metal powder needs to be reduced, when the mold box 112 is moved out of the interior of the operating table 1, the mold box 112 drives the storage wheel 321 to rotate through the pull plate 31 and the pull rope 322, so that the storage wheel 321 drives the torsion spring to stretch through the auger rod 32. When the mold box 112 returns to its initial state, the torsion spring returns to its initial state, and then drives the auger rod 32 to rotate, so that the auger rod 32 drives the metal powder into the interior of the feed port 342 through the barrel groove, and then the control panel 13 is first used to control the metal powder. The solenoid valve 344 on the surface of the feed port 342 is opened and the drive motor 33 is started. When the metal powder enters the interior of the receiving tray 34, the solenoid valve 344 on the surface of the feed port 342 is closed. The drive motor 33 drives the receiving tray 34 and the extension tray 347 to rotate via the rotating cylinder 331, so that the grinding balls inside the receiving tray 34 grind the metal powder. As the receiving tray 34 and the extension tray 347 continue to rotate, the calcium flakes absorb oxygen inside the metal powder, thereby reducing the oxygen content inside the metal powder. For specific example 4, please refer to Figures 1 to 16 According to the gantry-type casting mold 3D printing device provided in the third embodiment, this embodiment provides a further technical solution: The distinguishing component 4 includes a second cylinder 41 fixedly connected to the back of the processing box 14 and a rotating rod 42 rotatably connected to the inside of the extension disk 347.

The push gear 452 is meshed with the push tooth plate 423 for transmission. The operating slot 45 is slidably connected to a limit tooth plate 454 inside, and the limit tooth plate 454 is meshed with the lifting gear 453 for transmission. A limit slot for the limit tooth plate 454 to be inserted is opened inside the storage tray 34; It should be noted that the extension disc 347 is also provided with a plurality of sieve holes 345 inside. When the extension disc 347 is received in the annular groove 341, the plurality of sieve holes 345 inside the extension disc 347 overlap with the plurality of sieve holes 345 inside the receiving disc 34. When the solenoid valve 344 on the surface of the discharge port 343 is opened, the plurality of sieve holes 345 inside the receiving disc 34 are opened. When it is necessary to separate the processed metal powder from other objects, the second cylinder 41 is started through the control panel 13. The second cylinder 41 drives the extension plate 347 to be stored in the annular groove 341 through the second telescopic column 411. When the extension plate 347 moves toward the annular groove 341, the dividing plate 421, the insert block 422 and the pushing tooth plate 423 on the surface of the rotating rod 42 gradually move toward the receiving plate 34, so that the insert block 422 is gradually inserted into the interior of the slot 44. During the movement, the pushing tooth plate 423 drives the rotating rod 451 to rotate through the pushing gear 452, so that the rotating rod 451 drives the limiting tooth plate 454 to be gradually stored in the rotating rod 451 through the lifting gear 453. The interior of the cylinder 331 is rotated, thereby changing the state between the rotating cylinder 331 and the receiving tray 34 from a snap connection to a rotating connection. When the extension tray 347 is received in the receiving tray 34, the dividing plate 421 divides the grinding balls, calcium flakes and metal powder in the receiving tray 34 into several areas. Then the driving motor 33 is started again and the solenoid valve 344 on the surface of the discharge port 343 is opened. The driving motor 33 drives the rotating rod 42 to rotate through the rotating cylinder 331, causing the rotating rod 42 to rotate the grinding balls, calcium flakes and metal powder through the dividing plate 421, thereby causing the metal powder to flow out from the inside of the sieve hole 345, while the grinding balls and calcium flakes remain in the receiving tray 34 and the extension tray 347. Specific embodiment 5, the present invention also provides a gantry type casting mold 3D printing method, the gantry type casting mold 3D printing method specifically comprises the following steps: Step 1: Pour metal powder into the powder box 122, and then use the mobile platform 12 to drive the printer 121 to move, so that the printer 121 casts the metal powder into a mold and places it in the mold box 112; Step 2: When the printed mold is pushed out of the operating table 1 through the mold box 112, the recovery component 2 is activated to recover the metal powder that falls into the operating table 1; Step 3: When the recycling component 2 is driven, the recycling component 2 transports the metal powder into the interior of the deoxidation component 3, so that the deoxidation component 3 reduces the oxygen content inside the metal powder; Step 4: When the metal powder with reduced oxygen content needs to be distinguished from other substances, the distinguishing component 4 is started to enable the distinguishing component 4 and the oxygen reduction component 3 to distinguish the metal powder.

[0025] Working principle: When in use, when it is necessary to print the mold, pour the metal powder into the powder box 122, and then start the mobile platform 12 through the control panel 13, so that the mobile platform 12 drives the powder box 122 and the printer 121 to move, so that the metal powder inside the powder box 122 is laid inside the mold box 112, and then the printer 121 prints the metal powder into a gantry-type casting mold and places it inside the mold box 112, and then starts the first cylinder 11 through the control panel 13, so that the first cylinder 11 drives the mold box 112 to move through the first telescopic column 111, and then the mold box 112 drives the printed gantry-type casting mold out of the interior of the operating table 1, and when it is necessary to recycle the residual metal powder that falls inside the operating table 1 When the mold box 112 moves, the mold box 112 drives the pushing rod 211 to move through the pushing plate 21, so that the pushing rod 211 drives the pushing plate 212 to move inside the air cylinder 22, and then the air inside the air cylinder 22 is transported to the inside of the fixed cylinder 23 through the air pipe 221. As the air pressure inside the fixed cylinder 23 continues to increase, the sealing plate 231 moves inside the fixed cylinder 23. During the movement, the sealing plate 231 drives the recovery plate 234 to move through the pushing rod 232, so that the recovery plate 234 pushes the residual metal powder that falls inside the operating table 1, so that the residual metal powder enters the inside of the cylinder groove through the recovery groove. When the oxygen content inside the recovered metal powder needs to be reduced, when the mold box 112 is moved out of the operating table 1, the mold box 112 drives the receiving wheel 321 to rotate through the pull plate 31 and the pull rope 322, so that the receiving wheel 321 drives the torsion spring to stretch through the auger rod 32. When the mold box 112 returns to its initial state, the torsion spring returns to its initial state, thereby driving the auger rod 32 to rotate, so that the auger rod 32 drives the metal powder into the feed port 342 through the barrel groove. Then, the solenoid valve 344 on the surface of the feed port 342 is opened through the control panel 13 and then the drive motor 33 is started. When the metal powder enters the interior of the receiving tray 34, the solenoid valve 344 on the surface of the feed port 342 is closed, and the drive motor 33 drives the receiving tray 34 and the extension tray 347 to rotate through the rotating barrel 331, so that the grinding balls inside the receiving tray 34 grind the metal powder. During grinding, as the receiving tray 34 and the extension tray 347 continuously rotate, the calcium sheet absorbs the oxygen inside the metal powder, thereby reducing the oxygen content inside the metal powder. When the processed metal powder needs to be separated from other objects, the second cylinder 41 is started through the control panel 13. The second cylinder 41 drives the extension tray 347 to be stored inside the annular groove 341 through the second telescopic column 411. In the process of the extension tray 347 moving toward the annular groove 341, the dividing plate 421, the insert block 422 and the pushing tooth plate 423 on the surface of the rotating rod 42 gradually move toward the direction of the receiving tray 34, so that the insert block 422 is gradually inserted into the interior of the slot 44. In the process of moving, the pushing tooth plate 423 drives the rotating rod 451 to rotate by pushing the gear 452.The rotating rod 451 drives the limiting toothed plate 454 through the lifting gear 453 to gradually be stored inside the rotating cylinder 331, thereby changing the state between the rotating cylinder 331 and the receiving tray 34 from a snap connection to a rotating connection. When the extension tray 347 is stored inside the receiving tray 34, the dividing plate 421 divides the grinding balls, calcium flakes, and metal powder inside the receiving tray 34 into several areas. The drive motor 33 is then restarted and the solenoid valve 344 on the surface of the discharge port 343 is opened. The drive motor 33 drives the rotating rod 42 through the rotating cylinder 331 to rotate, causing the rotating rod 42 to rotate the grinding balls, calcium flakes, and metal powder through the dividing plate 421, causing the metal powder to flow out from the inside of the screening hole 345, while the grinding balls and calcium flakes remain inside the receiving tray 34 and the extension tray 347.
