Description

Technical Field

[0001] This application relates to the field of metal casting technology, and in particular to a tilting gravity casting machine system. Background Technology

[0002] Metal casting is a fundamental process in fields such as machinery manufacturing, automotive parts, and hardware processing. It mainly involves injecting molten metal into the cavity of a mold, and then cooling, solidifying, and shaping it to obtain the desired metal casting.

[0003] In the existing gravity casting process for aluminum alloys, workers need to use iron ladles to scoop a fixed amount of molten aluminum from a high-temperature aluminum bath, manually transfer it to the die-casting machine, and then slowly pour the molten aluminum into the mold cavity of the die-casting machine. After the molten aluminum is completely poured in, the tilting device provided with the mold drives the entire mold to tilt and adjust its angle, so that the molten aluminum in the mold cavity flows smoothly under the action of gravity and fully fills all areas of the cavity, thus completing the complete gravity casting process.

[0004] However, the existing casting process mainly relies on manual scooping, transporting, and pouring of molten aluminum. Due to subjective factors such as the speed and physical strength of manual operation, the overall casting efficiency is low. Secondly, the melting temperature of molten aluminum is extremely high. During the operation, workers need to be in close contact with the high-temperature molten aluminum and high-temperature equipment. They are in a high-temperature and harsh working environment for a long time, which makes them prone to safety accidents such as molten aluminum splashing and high-temperature burns. The risk to workers is extremely high, and there are safety hazards. It is impossible to balance production efficiency and work safety. Summary of the Invention

[0005] To improve the efficiency and safety of casting operations, this application provides a tilting gravity casting machine system.

[0006] The tilting gravity casting machine system provided in this application adopts the following technical solution: A tilting gravity casting machine system includes a tilting device, a feeding assembly, and a casting assembly. The feeding assembly includes an aluminum pool containing molten metal. The casting assembly includes a machine platform disposed between the aluminum pool and the tilting device. A turntable is rotatably connected to the machine platform. A robotic arm mounting base is fixedly mounted on the turntable. A first robotic arm is rotatably connected to the robotic arm mounting base. A second robotic arm is rotatably connected to the free end of the first robotic arm. A third robotic arm is rotatably connected to the end of the second robotic arm away from the first robotic arm. A tilting motor is disposed at the free end of the third robotic arm. A pouring cup holder is disposed on the output shaft of the tilting motor. A pouring cup is disposed on the pouring cup holder.

[0007] By adopting the above technical solution, during the casting operation, the turntable drives the robotic arm mounting base to rotate and adjust the overall orientation. In conjunction with the multi-stage linkage rotation of the first, second, and third robotic arms, the spatial position of the pouring cup is adjusted, suspending and positioning the pouring cup above the aluminum bath for material retrieval. Subsequently, the third robotic arm drives the end pouring cup down to approach the aluminum bath, the tilting motor starts and adjusts the tilting posture of the pouring cup, so that the pouring cup extends into the aluminum bath to complete the aluminum scooping. After the pouring cup is filled with a sufficient amount of aluminum, the robotic arms work together to lift the pouring cup, the turntable rotates in the opposite direction to reset, and the pouring cup containing aluminum is transferred to the mold cavity above the tilting device. After being positioned again by the multi-stage robotic arms, the tilting motor drives the pouring cup holder and the pouring cup to tilt, pouring the internal aluminum into the mold cavity, and completing the subsequent casting and molding process in conjunction with the tilting device. This automates the scooping, transfer, and pouring of molten aluminum, eliminating the need for manual handling of the molten aluminum and high-temperature equipment by holding an iron ladle and coming into close contact with them, thus improving the efficiency and safety of metal casting production.

[0008] Optionally, the feeding assembly further includes a heating furnace and a transition pool. The transition pool is connected to the discharge end of the heating furnace. A connecting pipe connected to the aluminum molten pool is provided at the bottom of the transition pool. A retrieval assembly for retrieving impurities is provided on the transition pool.

[0009] By adopting the above technical solution, aluminum blocks are transported into the heating furnace, where they are heated and melted into molten aluminum. The molten metal is then transferred to a transition tank for initial sedimentation. Oxide scale, slag, and various light impurities float on the surface of the filter tank, and the retrieval component removes these floating impurities. The purified aluminum then flows into the aluminum pool through a connecting pipe, thus ensuring that the aluminum used for subsequent casting has a low impurity content and guarantees casting quality.

[0010] Optionally, the salvage assembly includes a movable frame arranged along the length of the transition pool. An X-axis linear guide rail is mounted on the movable frame. A salvage frame is fixedly mounted on the movable part of the X-axis linear guide rail. A drive shaft is rotatably connected to the salvage frame. Drive sprockets are coaxially mounted at both ends of the axial direction of the drive shaft. Guide sprockets are rotatably connected to both radial sides of each drive sprocket on the salvage frame. A lifting motor that drives the drive shaft is mounted on the salvage frame. A drive chain is meshed on the outer surface of each drive sprocket. One end of the drive chain passes over one of the guide sprockets and is equipped with a counterweight. The other end passes over the other guide sprocket and is rotatably connected to a connecting rod. A salvage bucket for salvaging impurities is jointly mounted on both connecting rods.

[0011] By adopting the above technical solution, during the salvage operation, the X-axis linear guide rail moves the salvage frame to the salvage position above the transition pool. Then, the lifting motor drives the drive shaft to rotate two drive sprockets. The drive sprockets drive the meshing drive chain in a cyclic transmission motion. Under the guiding and limiting action of the guide sprockets on both sides, and with the gravity balance of the counterweight, the connecting rod moves vertically downward, causing the connecting rod to immerse the salvage bucket into the transition pool. Subsequently, the X-axis linear guide rail moves the salvage frame along the length of the transition pool, causing the salvage bucket submerged at the liquid surface to slide synchronously with the frame, scraping the scum on the surface of the aluminum liquid in the transition pool into the salvage bucket. When the salvage bucket moves to the other end of the transition pool, the lifting motor rotates in the opposite direction, causing the salvage bucket to move out of the liquid surface of the transition pool. This achieves the removal of scum inside the transition pool without the need for manual operation by workers, further improving the safety of the casting operation.

[0012] Optionally, the transition pool is provided with an impurity box at its end along the length direction, the movable frame and the X-axis linear guide extend to the outer surface of the impurity box, and the impurity box is provided with limit protrusions on both opposite sides along the width direction. When the retrieval bucket moves to abut against the limit protrusions, the opening of the retrieval bucket faces the impurity box.

[0013] By adopting the above technical solution, when the X-axis linear guide rail drives the salvage bucket to move to contact the limiting protrusion, the limiting protrusion will block and limit the salvage bucket and the connecting rod due to the movable connection between the connecting rod and the drive chain. This restricts the connecting rod from continuing to move in the same direction with the drive chain, thereby causing the salvage bucket to flip and tilt relative to the drive chain. At this time, the opening of the salvage bucket faces the impurity box, and the scum inside falls into the impurity box. This achieves the unloading and cleaning of impurities inside the salvage bucket without the need for manual cleaning of the salvage bucket.

[0014] Optionally, each of the counterweights has a guide block on its outer surface, and the retrieval frame has a guide groove that slides with the guide block in the vertical direction. Each drive chain has a limiting component at its end, which limits the movement of the connecting rod and the end of the drive chain.

[0015] By adopting the above technical solution, the setting of the guide block and guide groove restricts the overall posture of the counterweight, so that the drive chain always slides regularly in the vertical direction, ensuring the stability of the lifting and lowering process of the salvage bucket. When the salvage bucket needs to perform salvage operation, the limiting component restricts the range of motion at the connection between the connecting rod and the drive chain, reducing the possibility of the salvage bucket deflecting and tilting due to the buoyancy of the aluminum liquid. This ensures that the salvage bucket maintains the correct salvage posture and is immersed in the transition pool, avoiding abnormal salvage bucket posture from affecting the scum salvage effect, thus ensuring the smooth progress of the salvage operation.

[0016] Optionally, the limiting component includes a limiting plate fixedly disposed at the end of the drive chain. The limiting plate and the connecting rod have interconnected mounting holes. A limiting post passes through the mounting holes. A first dynamic friction ring and a second dynamic friction ring are slidably connected to the limiting post along the axial direction. The first and second dynamic friction rings are respectively disposed on both sides of the connecting rod in the width direction. The limiting post has a first limiting groove and a second limiting groove along the axial direction. A first magnetic block and a second magnetic block are respectively disposed on the inner peripheral sidewalls of the first and second dynamic friction rings. The first magnetic block is slidably connected inside the first limiting groove, and the second magnetic block is slidably connected inside the second limiting groove. A first electromagnetic block that attracts and cooperates with the first magnetic block is disposed inside the first limiting groove, and a second electromagnetic block that attracts and cooperates with the second magnetic block is disposed inside the second limiting groove. Static friction plates are disposed on both the end face of the limiting plate facing the connecting rod and the opposite end face of the connecting rod.

[0017] By adopting the above technical solution, when it is necessary to restrict the degree of motion, the first electromagnetic block and the second electromagnetic block are synchronously energized so that they generate attraction forces on the first magnetic block and the second magnetic block respectively. Under the electromagnetic force, both the first moving friction ring and the second moving friction ring move towards the limiting plate. When the first moving friction ring moves, it abuts against the outer surface of the static friction plate of the limiting plate. When the second moving friction ring moves, it pushes the connecting rod to move until it abuts against the first moving friction ring. At this time, the second moving friction ring abuts against the static friction plate of the connecting rod. At this time, the first moving friction ring and the second moving friction ring are pressed tightly against the static friction plates on the end faces of the connecting rod and the limiting plate respectively. The high-intensity static friction force generated by the contact between the moving friction ring and the static friction plate eliminates the gap between the connecting rod and the limiting plate, locking the relative sway and rotational allowance between the two, thereby clamping and fixing the connecting rod to the limiting plate, and realizing the restriction of the rotational freedom of the connecting rod and the limiting plate.

[0018] Optionally, a first threaded post is provided at one end of the limiting post near the limiting plate, and a second threaded post is provided at the opposite end. A threaded groove is provided in the limiting plate to engage with the first threaded post. The threaded groove communicates with the mounting hole. An abutment ring is provided on the first threaded post, and the abutment ring abuts against the end of the limiting plate away from the connecting rod. A limiting ring is threadedly connected to the outer surface of the second threaded post. When the first electromagnetic block and the second electromagnetic block are not energized, the limiting ring abuts against the outer surface of the second dynamic friction ring.

[0019] By adopting the above technical solution, when installing the limiting component, the worker inserts the limiting post into the mounting hole. When the first threaded post moves to the threaded groove, the limiting post is rotated to make the first threaded post engage and lock with the threaded groove until the abutment ring tightly abuts against the end of the limiting plate away from the connecting rod, thus achieving the installation and positioning of the limiting post. Then, the first magnetic block on the first moving friction ring is aligned with the first limiting groove and slid in. Next, the connecting rod is aligned with the limiting post and inserted. Finally, the second magnetic block on the second moving friction ring is aligned with the second limiting groove and slid in, so that the first moving friction ring and the second moving friction ring are respectively arranged on the two end faces of the connecting rod. Finally, the limiting ring is screwed into the second threaded post, so that the limiting ring tightly abuts against the outer surface of the second moving friction ring to form an axial limit, thus completing the overall assembly of the limiting component.

[0020] In summary, this application includes at least one of the following beneficial technical effects: This application automates the scooping, transfer and pouring of molten aluminum by setting up a feeding component and a pouring component. The entire process does not require manual handling of the molten aluminum and high-temperature equipment by holding an iron spoon, which improves the efficiency and safety of metal casting production. This application sets up a salvage component to salvage and remove floating impurities. The purified aluminum liquid then flows into the aluminum pool through a connecting pipe, thus ensuring that the aluminum liquid used for subsequent casting has a low impurity content and guarantees the casting quality. This application limits the range of motion at the connection between the connecting rod and the drive chain by restricting the components, thereby reducing the possibility of the retrieval bucket deflecting and tilting due to the buoyancy of the molten aluminum. This ensures that the retrieval bucket maintains the correct retrieval posture when immersed in the transition pool, preventing abnormal retrieval posture from affecting the scum retrieval effect and thus ensuring the smooth progress of the retrieval operation.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0028] This application discloses a tilting gravity casting machine system.

[0029] Reference Figure 1 and Figure 2 A tilting gravity casting machine system includes a feeding assembly 1, a casting assembly 2, and a tilting device (not shown in the figure) arranged sequentially. The feeding assembly 1 includes a heating furnace 101, a transition pool 102, and an aluminum water pool 103. The transition pool 102 is connected to the discharge end of the heating furnace 101. A connecting pipe (not shown in the figure) is provided at the bottom of the transition pool 102 and connects to the aluminum water pool 103. The aluminum water pool 103 stores molten metal. In this embodiment, the tilting device and the heating furnace 101 are both existing technologies in the casting field, and their specific composition and principle are also existing technologies, which will not be described in detail in this embodiment.

[0030] The aluminum block is conveyed into the heating furnace 101, where it is heated and melted into molten aluminum. The molten metal is then transferred to the transition pool 102 for initial sedimentation. Oxide scale, slag, and various light impurities float on the surface of the filter pool. The molten liquid at the bottom flows through the connecting pipe into the aluminum water pool 103, providing raw materials for subsequent casting.

[0031] Reference Figure 1 and Figure 2To ensure the quality of the molten aluminum inside the aluminum pool 103, a retrieval assembly 3 is provided on the transition pool 102. Specifically, the retrieval assembly 3 includes a movable frame 31 arranged along the length of the transition pool 102. Both ends of the movable frame 31 extend to the outside of the transition pool 102. An X-axis linear guide rail 32 is fixedly installed on the movable frame 31. A retrieval frame 33 is fixedly installed on the movable part of the X-axis linear guide rail 32. A drive shaft 34 is rotatably connected to the retrieval frame 33. The axis of the drive shaft 34 is parallel to the width direction of the transition pool 102. Both ends of the drive shaft 34 are coaxially fixedly connected to drive sprockets 35. Guide sprockets 36 are rotatably connected to both radial sides of each drive sprocket 35 on the retrieval frame 33. A lifting motor 37 is installed on the outer surface of the retrieval frame 33. The output shaft of the lifting motor 37 is coaxially fixedly connected to the drive shaft 34.

[0032] Reference Figure 1 and Figure 2 Each drive sprocket 35 has a drive chain 38 meshing on its outer surface. One end of the drive chain 38 passes over one of the guide sprockets 36 and is fixedly connected to a counterweight 39. The other end passes over another guide sprocket 36 and is movably connected to a connecting rod 4. A retrieval bucket 310 for retrieval of impurities is mounted on both connecting rods 4. When the connecting rod 4 is vertical, the retrieval bucket 310 is in a retrieval posture. Guide blocks 391 are fixedly connected to the opposite end faces of the counterweight 39. The retrieval frame 33 has a guide groove 331 that slides with the guide block 391 in the vertical direction. The sliding engagement of the guide block 391 and the guide groove 331 restricts the overall posture of the counterweight 39 and the drive chain 38, so that the drive chain 38 always slides regularly in the vertical direction, thereby ensuring the stability of the retrieval bucket 310 during the lifting process.

[0033] Reference Figure 1 and Figure 2 A sludge box 5 is fixedly connected to the starting end of the transition pool 102 away from the X-axis linear guide 32. The moving frame 31 and the X-axis linear guide 32 extend to the outer surface of the sludge box 5. Limiting protrusions 51 are fixedly connected to both sides of the sludge box 5 along the width direction. The limiting protrusions 51 are set along the length of the X-axis linear guide 32 and are located below the central axis of the retrieval bucket 310. The width of the limiting protrusions 51 is greater than the gap between the retrieval bucket 310 and the fixed plate. When the retrieval bucket 310 moves to abut against the limiting protrusions 51, the opening of the retrieval bucket 310 faces the sludge box 5.

[0034] When a large amount of scum appears on the surface of the transition pool 102, the worker starts the X-axis linear guide 32 to move the retrieval frame 33 to the retrieval position above the transition pool 102. Then, the lifting motor 37 drives the drive shaft 34 to rotate the two drive sprockets 35. The drive sprockets 35 drive the meshing drive chain 38 to perform cyclic transmission. Under the guiding and limiting action of the guide sprockets 36 on both sides, and with the gravity balance of the counterweight 39, the connecting rod 4 moves vertically downward, so that the connecting rod 4 drives the retrieval bucket 310 to be submerged in the transition pool 102. Then, the X-axis linear guide 32 drives the retrieval frame 33 to move along the length of the transition pool 102, so that the retrieval bucket 310 submerged in the liquid surface slides synchronously with the frame, scraping the scum on the surface of the aluminum liquid in the transition pool 102 into the retrieval bucket 310. When the retrieval bucket 310 moves to the other end of the transition pool 102, the lifting motor 37 drives the drive shaft 34 to rotate in the opposite direction. The drive shaft 34 drives the two drive sprockets 35 to rotate in the opposite direction. At this time, the drive chain 38 is wound up and lifted, and the chain traction connecting rod 4 moves vertically upward, thereby pulling the retrieval bucket 310 with scum away from the aluminum liquid surface of the transition pool 102. Then, the X-axis linear guide rail 32 continues to drive the retrieval frame 33 and the retrieval bucket 310 to move horizontally towards the impurity box 5. When the retrieval bucket 310 moves to abut against the limiting protrusion 51, the limiting protrusion 51 prevents the retrieval bucket 310 and connecting rod 4 from continuing to move with the retrieval frame 33. Meanwhile, the retrieval frame 33 continues to move forward, driving the drive chain 38 to move as a whole. Since the connecting rod 4 and the drive chain 38 are movably connected, the retrieval bucket 310 and the connecting rod 4 are flipped and deflected relative to the drive chain 38, so that the opening of the retrieval bucket 310 faces downward and is aligned with the impurity box 5. The scum collected in the retrieval bucket 310 falls into the impurity box 5 under the action of gravity, automatically completing the unloading operation. The retrieval component 3 enables the automatic collection and unloading of scum, allowing the purified aluminum liquid to flow into the aluminum water pool 103 through the connecting pipe. This ensures that the impurity content of the aluminum liquid used for subsequent casting is low, thereby ensuring the casting quality.

[0035] Reference Figure 2 and Figure 3 To improve the stability of the salvage process, a limiting component 6 is provided at the end of each drive chain 38. When the salvage bucket 310 needs to perform salvage operation, the limiting component 6 restricts the movement of the connection between the connecting rod 4 and the drive chain 38, reducing the possibility of the salvage bucket 310 deflecting and tilting due to the buoyancy of the molten aluminum. This ensures that the salvage bucket 310 maintains the correct salvage posture and is immersed in the transition pool 102, avoiding abnormal posture of the salvage bucket 310 from affecting the scum salvage effect, thereby ensuring the smooth progress of the salvage operation.

[0036] Reference Figure 3 and Figure 4The limiting component 6 includes a limiting plate 61 fixedly installed at the end of the drive chain 38. The limiting plate 61 and the connecting rod 4 have interconnected mounting holes 7. A limiting post 62 passes through the mounting hole 7. A first threaded post 621 is coaxially fixedly connected to one end of the limiting post 62 near the limiting plate 61, and a second threaded post 622 is coaxially fixedly connected to the other end. A threaded groove 71 is opened in the limiting plate 61 to thread with the first threaded post 621. The threaded groove 71 communicates with the mounting hole 7 on the limiting plate 61, and the diameter of the mounting hole 7 is smaller than the diameter of the threaded groove 71. An abutment ring 623 is coaxially fixedly connected to the first threaded post 621. When the first threaded post 621 is screwed into the threaded groove 71, the abutment ring 623 abuts against the end of the limiting plate 61 away from the connecting rod 4.

[0037] Reference Figure 3 and Figure 4 The limiting post 62 is slidably connected with a first moving friction ring 63 and a second moving friction ring 64 along the axial direction. The first moving friction ring 63 and the second moving friction ring 64 are respectively disposed on both sides of the connecting rod 4 in the width direction. The first moving friction ring 63 is disposed at the end of the connecting rod 4 near the limiting plate 61. The limiting post 62 has a first limiting groove 624 and a second limiting groove 625 along the axial direction. The first limiting groove 624 and the second limiting groove 625 are arranged opposite to each other in the radial direction of the limiting post 62. The length of the first limiting groove 624 is greater than that of the second limiting groove 625. The first moving friction ring 63 and the second moving friction ring... A first magnetic block 65 and a second magnetic block 66 are fixedly connected to the inner peripheral sidewall of 64. The first magnetic block 65 is slidably connected inside the first limiting groove 624, and the second magnetic block 66 is slidably connected inside the second limiting groove 625. A first electromagnetic block 67 that attracts and cooperates with the first magnetic block 65 is fixedly installed at the end of the first limiting groove 624 near the limiting plate 61. A second electromagnetic block 68 that attracts and cooperates with the second magnetic block 66 is fixedly installed at the end of the second limiting groove 625 near the limiting plate 61. Static friction plates 69 are fixedly embedded on the end face of the limiting plate 61 facing the connecting rod 4 and the end face opposite to the connecting rod 4.

[0038] Reference Figure 3 and Figure 4 The outer surface of the second threaded post 622 is threaded with a limiting ring 626. When the first electromagnetic block 67 and the second electromagnetic block 68 are not energized, the limiting ring 626 abuts against the outer surface of the second dynamic friction ring 64.

[0039] When installing the limiting component 6, the worker inserts the limiting post 62 into the mounting hole 7. When the first threaded post 621 moves to the threaded groove 71, the limiting post 62 is rotated so that the first threaded post 621 engages with the threaded groove 71 and locks until the abutment ring 623 tightly abuts against the end of the limiting plate 61 away from the connecting rod 4, thereby achieving the installation and positioning of the limiting post 62. Then, the first magnetic block 65 on the first moving friction ring 63 is aligned with the first limiting groove 624 and slid in. Next, the connecting rod 4 is aligned with the limiting post 62 and inserted. Finally, the second magnetic block 66 on the second moving friction ring 64 is aligned with the second limiting groove 625 and slid in, so that the first moving friction ring 63 and the second moving friction ring 64 are respectively arranged on the two end faces of the connecting rod 4. Finally, the limiting ring 626 is screwed into the second threaded post 622, so that the limiting ring 626 tightly abuts against the outer surface of the second moving friction ring 64 to form an axial limit. In this way, the overall assembly of the limiting component 6 is completed. When it is necessary to restrict the degree of motion, the first electromagnetic block 67 and the second electromagnetic block 68 are simultaneously energized so that they generate attraction forces on the first magnetic block 65 and the second magnetic block 66, respectively. Under the electromagnetic force, the first moving friction ring 63 and the second moving friction ring 64 both move toward the limiting plate 61. When the first moving friction ring 63 moves, it abuts against the outer surface of the static friction plate 69 of the limiting plate 61. When the second moving friction ring 64 moves, it pushes the connecting rod 4 to abut against the first moving friction ring 63. At this time, the second moving friction ring 64 abuts against the static friction plate 69 of the connecting rod 4. At this time, the first moving friction ring 63 and the second moving friction ring 64 are pressed tightly against the static friction plate 69 on the end face of the connecting rod 4 and the limiting plate 61, respectively. The high-intensity static friction force generated by the contact between the moving friction ring and the static friction plate 69 eliminates the gap between the connecting rod 4 and the limiting plate 61, locking the relative sway and rotational allowance between the two, thereby clamping and fixing the connecting rod 4 to the limiting plate 61, and realizing the restriction of the rotational freedom of the connecting rod 4 and the limiting plate 61.

[0040] Reference Figure 5 The casting assembly 2 includes a machine platform 21 disposed between the aluminum water tank 103 and the tilting device. A turntable 22 is rotatably connected to the machine platform 21. A robotic arm mounting base 23 is fixedly disposed on the turntable 22. A first robotic arm 24 is rotatably connected to the robotic arm mounting base 23. A second robotic arm 25 is rotatably connected to the free end of the first robotic arm 24. A third robotic arm 26 is rotatably connected to the end of the second robotic arm 25 away from the first robotic arm 24. A flip motor 27 is mounted on the free end of the third robotic arm 26. A pouring cup holder 28 is fixedly connected to the output shaft of the flip motor 27. A pouring cup 29 is fixedly connected to the pouring cup holder 28. In this embodiment, the rotation of the first robotic arm 24 is achieved by an independent servo drive motor in conjunction with a reduction mechanism. The rotation of the second robotic arm 25 and the third robotic arm 26 is achieved by a small servo swing motor. The turntable 22 is existing technology in the field of rotating devices. Its specific composition and principle will not be described in this embodiment.

[0041] During the casting process, the turntable 22 drives the robotic arm mounting base 23 to rotate and adjust the overall orientation. In conjunction with the multi-stage linkage rotation of the first robotic arm 24, the second robotic arm 25, and the third robotic arm 26, the spatial position of the pouring cup 29 is adjusted, suspending and positioning the pouring cup 29 above the aluminum bath 103 for material retrieval. Subsequently, the third robotic arm 26 moves the end pouring cup 29 down closer to the aluminum bath 103. The tilting motor 27 is started and adjusts the tilting posture of the pouring cup 29, so that the pouring cup 29 extends into the aluminum bath 103 to scoop up the molten aluminum. After the pouring cup 29 is filled with a sufficient amount of molten aluminum, the robotic arms work together to lift the pouring cup 29, and the turntable 22 rotates in the opposite direction to reset, transferring the pouring cup 29 filled with molten aluminum to the mold cavity above the tilting device. After being positioned again by the multi-stage robotic arms, the tilting motor 27 drives the pouring cup holder 28 and the pouring cup 29 to tilt, pouring the molten aluminum into the mold cavity, and completing the subsequent casting and molding process in conjunction with the tilting device. This automates the scooping, transfer, and pouring of molten aluminum, eliminating the need for manual handling of the molten aluminum and high-temperature equipment by holding an iron ladle and coming into close contact with them, thus improving the efficiency and safety of metal casting production.

[0042] The implementation principle of the tilting gravity casting machine system in this application embodiment is as follows: During the casting operation, the turntable 22 drives the robotic arm mounting base 23 to rotate and adjust the overall orientation. This, combined with the multi-stage linkage rotation of the first robotic arm 24, the second robotic arm 25, and the third robotic arm 26, achieves spatial position adjustment of the pouring cup 29, suspending and positioning it above the aluminum bath 103 at the material collection position. Subsequently, the third robotic arm 26 drives the end pouring cup 29 to move down closer to the aluminum bath 103, and the tilting motor 27 starts and adjusts the pouring... The tilted position of the pouring cup 29 allows it to be inserted into the aluminum molten pool 103 to scoop up the molten aluminum. Once the pouring cup 29 is filled with sufficient molten aluminum, the robotic arms work together to lift it, and the turntable 22 rotates in the opposite direction to reset, transferring the molten aluminum-filled pouring cup 29 to the mold cavity of the tilting device. After being positioned again by the multi-stage robotic arms, the tilting motor 27 drives the pouring cup holder 28 and the pouring cup 29 to tilt, pouring the molten aluminum into the mold cavity, thus completing the subsequent casting process in conjunction with the tilting device. This automates the scooping, transfer, and pouring of molten aluminum, eliminating the need for manual handling of the molten aluminum and high-temperature equipment, improving the efficiency and safety of metal casting production.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
