Description
Technical Field
[0001] This invention relates to the field of casting technology, and in particular to a GIS aluminum alloy casting equipment. Background Technology
[0002] GIS (Gas Insulated Metal Enclosed Switchgear) aluminum alloy housings are typically manufactured using low-pressure casting. These housings are characterized by large dimensions, uneven wall thickness, high airtightness requirements, and complex shapes. Existing GIS aluminum alloy casting equipment generally includes a fixed mold, a moving mold, a mold closing mechanism, and an ejection mechanism. The ejection mechanism pushes the casting out of the moving or fixed mold, allowing it to fall freely into the receiving hopper below or be retrieved manually or by a robotic arm. However, these existing devices have technical drawbacks. After ejection, the casting is usually in a free-fall or thrown state, making it prone to collisions with the receiving device or the ground, causing surface scratches, edge defects, and even internal micro-cracks. To avoid damage from falling parts, some equipment uses robotic arms or pneumatic grippers for retrieval. However, robotic arms are expensive and require complex programming and sensing systems. Furthermore, after ejection, there is a lack of effective support for the inner wall of the casting, making it (such as the GIS housing) susceptible to deformation under the external force of the robotic arm or pneumatic gripper, affecting subsequent assembly accuracy.
[0003] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention
[0004] In view of this, the purpose of this invention is to provide a GIS aluminum alloy casting equipment to solve the problem that the castings are easily deformed under the external force of a robotic arm or pneumatic gripper, which affects the subsequent assembly accuracy.
[0005] To achieve the above objectives, the present invention provides a GIS aluminum alloy casting equipment, including a casting table and a fixed mold fixedly installed above the casting table. A moving mold is provided above the casting table. A translation unit for driving the moving mold to move is installed on the casting table. An ejection mechanism is installed on the moving mold. A rotating shell is provided on the side of the moving mold facing the fixed mold. A receiving shell is provided inside the rotating shell. Both the rotating shell and the receiving shell have openings on the side facing the moving mold. The moving mold is equipped with a flipping structure for pushing the rotating shell to flip relative to the casting table. A support base for supporting the casting is fixedly connected inside the receiving shell. A limiting structure for limiting the position of the casting is installed on the rotating shell. A position adjustment unit for driving the receiving shell to move toward the moving mold is installed on the rotating shell. During the translation unit driving the moving mold to translate, the flipping structure causes the rotating shell to flip from below the moving mold to the side of the moving mold facing the fixed mold. After the moving mold reaches the ejection position, the position adjustment unit drives the receiving shell to contact the moving mold. The ejection mechanism pushes the casting into the receiving shell and is supported by the support base. The limiting structure limits the casting to be located inside the receiving shell. When the translation unit drives the moving mold to translate in the opposite direction, the flipping structure causes the rotating shell to carry the casting to the bottom of the moving mold to complete the unloading.

[0010] Optionally, the translation unit includes a fixed frame fixedly installed on the casting table, and the moving mold is slidably installed on the fixed frame. A first hydraulic telescopic rod is fixedly connected to the fixed frame, and the telescopic end of the first hydraulic telescopic rod is fixedly connected to the moving mold.
[0011] Optionally, the ejection mechanism includes a first movable seat disposed on the side of the moving mold away from the fixed mold. A plurality of first ejection rods are fixedly connected to the first movable seat, and the ends of the first ejection rods away from the first movable seat extend into the cavity of the moving mold. A second iron plate is fixedly connected to the first movable seat, and a second fixed post passes through the second iron plate. One end of the second fixed post is fixedly connected to the moving mold, and the other end of the second fixed post is fixedly connected to a first magnet block, which is in contact with the second iron plate. A second hydraulic telescopic rod is fixedly connected to the fixed frame, and the telescopic end of the second hydraulic telescopic rod is fixedly connected to a second magnet block, which is in contact with the second magnet block on the side of the second iron plate away from the moving mold.
[0012] Optionally, the limiting structure includes positioning seats respectively disposed on both sides of the support base. The inner walls of both sides of the housing shell are respectively provided with clearance holes adapted to the positioning seats. The two positioning seats are slidably installed in the two clearance holes, and the positioning seats penetrate the rotating shell. An elastic element adapted to the positioning seat is installed on the rotating shell. Movable columns are fixedly connected to both sides of the positioning seats. A support frame is provided on the side of the rotating shell away from the moving mold. The support frame has four inclined surfaces adapted to the movable columns. Several fixed sleeves are fixedly connected to the support frame. A sliding sleeve is provided on the outer side of the fixed sleeve. The sliding sleeve is fixedly connected to the outer wall of the rotating shell. A tension spring is provided inside the fixed sleeve. Both ends of the tension spring are fixedly connected to the support frame and the outer wall of the rotating shell, respectively. Several support rods are fixedly connected to the support frame. The end of the support rod away from the support frame extends into the rotating shell, and the end of the support rod away from the support frame abuts against the outer wall of the housing shell.
[0013] Optionally, the elastic element includes fixed seats that are fixedly installed on both sides of the rotating shell. A sliding groove is provided on the positioning seat, and a sliding plate is slidably arranged in the sliding groove.

Two support blocks adapted to the second support columns are fixedly connected to the top of the casting table.
[0015] The beneficial effects of this invention are as follows: The ejection mechanism directly ejects the casting into the receiving shell, avoiding impacts, deformation, or surface damage caused by the casting falling freely. This significantly improves the casting yield, eliminates reliance on dedicated robotic arms, and reduces equipment costs. The entire part picking and transfer process utilizes the opening action of the moving mold itself as the power source, and is completed through the mechanical linkage of the flipping structure and the position adjustment unit, eliminating the need for additional industrial robots or pneumatic grippers. This not only simplifies the control system but also significantly reduces equipment manufacturing and maintenance costs. Furthermore, the casting is reliably supported and limited within the receiving shell, preventing wobbling. The receiving shell is equipped with a support seat, which provides stable support to the inner wall of the casting after it is ejected. Simultaneously, the limiting structure constrains the position of the casting within the receiving shell, preventing wobbling or displacement during subsequent flipping or movement, thus ensuring the certainty of the casting's posture. Effective support of the inner wall of the casting prevents deformation, ensuring subsequent assembly accuracy. The receiving shell can automatically reset, ensuring continuous operation. Continuing the process, after the ejection mechanism pushes the casting into the receiving shell, it continues to push the casting, support base, and receiving shell to slide relative to the rotating shell, so that the receiving shell slides completely back into the rotating shell and resets to its initial position. This design allows the mechanism to return to its original state after each part removal, preparing for the next mold closing cycle without manual intervention. When the moving mold moves in the reverse direction and drives the rotating shell to rotate under the moving mold again, the casting is carried to the unloading station with the rotating shell. At this time, the casting can be naturally cooled or forced cooled at this position without occupying the mold closing area. This achieves spatial separation of casting, part removal, and cooling, which is beneficial to improving production efficiency and equipment utilization. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.
[0020] Example 1, by Figure 1 , Figure 2 , Figure 4 and Figure 5 The present invention includes a casting platform 1 and a fixed mold 2 fixedly installed above the casting platform 1. A movable mold 3 is provided above the casting platform 1. A translation unit for driving the movable mold 3 to translate is installed on the casting platform 1. An ejection mechanism is installed on the movable mold 3. A rotating shell 4 is provided on the side of the movable mold 3 facing the fixed mold 2. A receiving shell 5 is provided inside the rotating shell 4. Both the rotating shell 4 and the receiving shell 5 have openings on the side facing the movable mold 3. The moving mold 3 is equipped with a flipping structure for pushing the rotating shell 4 to flip relative to the casting table 1. A support base 6 for supporting the casting is fixedly connected inside the receiving shell 5. A limiting structure for positioning the casting is installed on the rotating shell 4. A position adjustment unit for driving the receiving shell 5 to move towards the moving mold 3 is also installed on the rotating shell 4. During the translation unit's translation of the moving mold 3, the flipping structure causes the rotating shell 4 to flip from below the moving mold 3 to the side of the moving mold 3 facing the fixed mold 2. After the moving mold 3 reaches the ejection position, the position adjustment unit drives the receiving shell 5 to contact the moving mold 3. The ejection mechanism pushes the casting into the receiving shell 5 and supports it with the support base 6. The limiting structure also limits the casting's position within the receiving shell 5. When the moving mold 3 is reversed and translated, the rotating shell 4, carrying the casting, is rotated to below the moving mold 3 via a flipping structure to complete the unloading. The moving mold 3 is then driven towards the fixed mold 2 via a translation unit, so that the fixed mold 2 and the moving mold 3 are closed together. After the casting is formed, the moving mold 3 is driven to translate via the translation unit, and the formed casting moves synchronously with the moving mold 3. As the moving mold 3 continues to translate, the rotating shell 4 is flipped from below the moving mold 3 to the side facing the fixed mold 2 via the flipping structure. At this time, the moving mold 3 is in the ejection position. The receiving shell 5 is driven towards the moving mold 3 via a position adjustment unit, and the receiving shell 5 contacts the moving mold 3. Then, the casting inside the moving mold 3 is ejected into the receiving shell 5 via the ejection mechanism. The support seat 6 inside shell 5 supports the inner wall of the casting. Then, the ejection mechanism pushes the casting, support seat 6, and receiving shell 5 to slide relative to the rotating shell 4, so that the receiving shell 5 slides completely back into the rotating shell 4. The receiving shell 5 returns to its initial position relative to the rotating shell 4. The support seat 6 supports the inner wall of the casting, and the limiting structure limits the position of the casting inside the receiving shell 5, preventing the casting from shaking inside the receiving shell 5. Then, the translation unit drives the moving mold 3 to translate in the opposite direction. The moving mold 3 can then drive the rotating shell 4 to rotate again to below the moving mold 3 through the flipping structure. The moving mold 3 and the fixed mold 2 can then close again. When the rotating shell 4 rotates to the unloading station, the casting can be cooled at the unloading station, achieving stable casting. The transfer and non-destructive material receiving process is achieved by driving the moving mold 3 to translate through the translation unit, allowing the casting to move synchronously with the moving mold 3 to the ejection station. Simultaneously, the rotating shell 4 is driven by the flipping structure to flip from below the moving mold 3 to the side of the moving mold 3 facing the fixed mold 2. Combined with the position adjustment unit, the receiving shell 5 is driven to contact the moving mold 3, and the ejection mechanism directly pushes the casting into the receiving shell 5. This process avoids the impact, deformation, or surface damage caused by the free fall of the casting, significantly improving the casting yield, eliminating the dependence on a dedicated robot, and reducing equipment costs. The entire part picking and transfer process uses the opening action of the moving mold 3 itself as the power source and is completed through the mechanical linkage of the flipping structure and the position adjustment unit, without the need for additional industrial robots or pneumatic grippers.This not only simplifies the control system but also significantly reduces equipment manufacturing and maintenance costs. Furthermore, the casting is reliably supported and restrained within the housing 5, preventing wobbling. The housing 5 contains a support seat 6, which provides stable support to the inner wall of the casting after it is pushed in. Simultaneously, the restraining structure constrains the position of the casting within the housing 5, preventing wobbling or displacement during subsequent flipping or movement, thus ensuring the stability of the casting's posture. Effective support of the inner wall of the casting prevents deformation, ensuring subsequent assembly accuracy. The housing 5 can automatically reset, ensuring the continuity of the operation cycle. After the ejector mechanism pushes the casting into the receiving shell 5, it continues to push the casting, support base 6, and receiving shell 5 to slide relative to the rotating shell 4, so that the receiving shell 5 slides completely back into the rotating shell 4 and returns to its initial position. This design allows the mechanism to return to its original state after each part removal, preparing for the next mold closing cycle without manual intervention. When the moving mold 3 moves in the reverse direction and drives the rotating shell 4 to rotate below the moving mold 3 again, the casting is carried to the unloading station with the rotating shell 4. At this time, the casting can be naturally cooled or forced cooled at this position without occupying the mold closing area. This achieves spatial separation of casting, part removal, and cooling, which is beneficial to improving production efficiency and equipment utilization.
[0021] Example 2, based on Example 1, is... Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8The position adjustment unit includes support parts 9 fixedly installed on both sides of the storage shell 5. A fixing plate 10 is provided on the side of the support part 9 away from the moving mold 3. The fixing plate 10 is fixedly connected to the inner wall of the rotating shell 4. Two first fixing posts 11 pass through the fixing plate 10. The first fixing posts 11 are fixedly connected to the support parts 9. A first compression spring 12 is sleeved on the outside of the first fixing posts 11, and both ends of the first compression spring 12 are fixedly connected to the support part 9 and the fixing plate 10, respectively. A locking component adapted to the first fixing posts 11 is installed on the rotating shell 4. The locking component includes a first iron plate 7 disposed on the side of the fixing plate 10 away from the support parts 9. An electromagnet 8 is contacted on the side of the first iron plate 7 away from the fixing plate 10, and the electromagnet 8 is fixedly connected to the inner wall of the rotating shell 4. Two adjacent first fixing posts 11 are fixedly connected to the corresponding first iron plates 7. The flipping structure includes a rotating shaft 13 located below the moving mold 3. The rotating shaft 13 is rotatably connected to the casting table 1. Two support plates 14 are fixedly sleeved on the outside of the rotating shaft 13. The support plates 14 are fixedly connected to the rotating shell 4. Several support rods 20 for supporting the rotating shell 4 are fixedly connected to the top of the casting table 1. Pushing components adapted to the support plates 14 are provided on both sides of the moving mold 3. The pushing components include pressing plates 15 rotatably installed on both sides of the moving mold 3. Side plates 16 are provided on the side of the two pressing plates 15 that are far apart. The side plates 16 are fixedly connected to the casting table 1. A rectangular hole 17 and a guide hole 18 are opened on the side plate 16. The guide hole 18 is inclined and one inner wall of the guide hole 18 is connected to one inner wall of the rectangular hole 17. A first support column 19 for reciprocating sliding in the rectangular hole 17 and the guide hole 18 is fixedly connected to the pressing plate 15. During the translation of the moving mold 3 driven by the translation unit, the moving mold 3 drives the first support column 19 to slide within the rectangular hole 17 via the pressing plate 15. After the pressing plate 15 contacts the support plate 14, as the moving mold 3 translates, the pressing plate 15 pushes the support plate 14 and the rotating shaft 13 to rotate relative to the casting table 1. The support plate 14 then drives the rotating shell 4 to flip. When the support plate 14 rotates to a preset angle, as the moving mold 3 translates, the first support column 19 slides from the rectangular hole 17 into the guide hole 18. The first support column 19 and the pressing plate 15 rotate relative to the moving mold 3. The pressing plate 15 presses down on the support plate 14 to make the support plate 14 and the rotating shaft 13 continue to rotate. When the pressing plate 15 rotates to the preset angle, the support plate 14 is in a horizontal state. At this time, the rotating shell 4 rotates to the side of the moving mold 3 facing the fixed mold 2, and the first compression spring 12 is in a compressed state. At this time, the electromagnet 8 is de-energized, and the electromagnet 8 no longer exerts force on the moving mold 3. The first iron plate 7 applies magnetic force, and the first compression spring 12 drives the support part 9 and the storage shell 5 to move toward the moving mold 3. Finally, the support part 9 and the storage shell 5 contact the moving mold 3 respectively. When the ejection mechanism pushes the casting into the storage shell 5 and is supported by the support seat 6, the ejection mechanism continues to push the casting, the support seat 6 and the storage shell 5 to slide relative to the rotating shell 4 so that the storage shell 5 is reset. The storage shell 5 drives the first iron plate 7 to contact the electromagnet 8 again through the support part 9. At this time, the electromagnet 8 is energized, and the first iron plate 7 and the electromagnet 8 are attracted together again. The storage shell 5 is fixed relative to the rotating shell 4. When the moving mold 3 moves in the opposite direction, similarly, the first support column 19 slides from the guide hole 18 into the rectangular hole 17, and the support plate 14 follows the pressing plate 15 to rotate in the opposite direction to the initial position. The rotating shell 4 rotates to the bottom of the moving mold 3 and is supported by the support rod 20. The rotating shell 4 rotates to the unloading station.
[0022] Example 3, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 and Figure 4The translation unit includes a fixed frame 50 fixedly mounted on the casting table 1, and a movable mold 3 slidably mounted on the fixed frame 50. A first hydraulic telescopic rod 21 is fixedly connected to the fixed frame 50, and the telescopic end of the first hydraulic telescopic rod 21 is fixedly connected to the movable mold 3. The ejection mechanism includes a first movable seat 22 disposed on the side of the movable mold 3 away from the fixed mold 2. A plurality of first ejection rods 23 are fixedly connected to the first movable seat 22, and the end of the first ejection rod 23 away from the first movable seat 22 extends into the cavity of the movable mold 3. A second iron plate 24 is fixedly connected to the moving base 22. A second fixed post 25 passes through the second iron plate 24. One end of the second fixed post 25 is fixedly connected to the moving mold 3. The other end of the second fixed post 25 is fixedly connected to a first magnet block 26. The first magnet block 26 is in contact with the second iron plate 24. A second hydraulic telescopic rod 27 is fixedly connected to the fixed frame 50. The telescopic end of the second hydraulic telescopic rod 27 is fixedly connected to a second magnet block 28. The side of the second iron plate 24 away from the moving mold 3 is in contact with the second magnet block 28. The moving mold 3 can be moved horizontally by sliding relative to the fixed frame 50 via the first hydraulic telescopic rod 21. When the moving mold 3 moves to the ejection position, the second magnetic block 28 is moved by the second hydraulic telescopic rod 27 so that the second magnetic block 28 comes into contact with the second iron plate 24. At this time, the second iron plate 24 and the second magnetic block 28 are magnetically fixed together. As the second magnetic block 28 continues to move horizontally, it drives the first movable seat 22 and the first ejector rod 23 to move via the second iron plate 24. The first ejector rod 23 pushes the casting in the moving mold 3 into the receiving shell 5, and the second iron plate 24 slides relative to the second fixed column 25. When the second magnetic block 28 is no longer magnetically attracted to the first magnetic block 26 and the casting does not need to be moved, the second hydraulic telescopic rod 27 drives the second magnetic block 28 to move in the opposite direction. The second magnetic block 28 drives the first movable seat 22 to move in the opposite direction through the second iron plate 24, so that the first ejector rod 23 returns to its initial position relative to the moving mold 3. Finally, the second iron plate 24 is magnetically attracted to the first magnetic block 26 again. As the second magnetic block 28 continues to move, the second iron plate 24 stops moving and the second magnetic block 28 no longer contacts the second iron plate 24. The first ejector rod 23 returns to its initial position relative to the moving mold 3. The first hydraulic telescopic rod 21 drives the moving mold 3 to move, and the moving mold 3 can then close with the fixed mold 2 again.
[0023] Example 4, based on Example 1, by Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 9 and Figure 10The limiting structure includes positioning seats 29 respectively disposed on both sides of the support base 6. The inner walls of both sides of the housing shell 5 are respectively provided with clearance holes 40 adapted to the positioning seats 29. The two positioning seats 29 are slidably installed in the two clearance holes 40 respectively, and the positioning seats 29 penetrate the rotating shell 4. Elastic elements adapted to the positioning seats 29 are installed on the rotating shell 4. Movable columns 30 are fixedly connected to both sides of the positioning seats 29. A support frame 31 is provided on the side of the rotating shell 4 away from the moving mold 3. The support frame 31 has four inclined surfaces adapted to the movable columns 30. Several fixed sleeves 33 are fixedly connected to the support frame 31. A sliding sleeve 34 is slidably fitted on the outside of the fixed sleeve 33. The sliding sleeve 34 is fixedly connected to the outer wall of the rotating shell 4. A tension spring 35 is provided inside the fixed sleeve 33. The two ends of the tension spring 35 are fixedly connected to the support frame 31 and the outer wall of the rotating shell 4 respectively. Several support rods 32 are fixedly connected to the support frame 31. The end of the support rod 32 away from the support frame 31 extends into the rotating shell 4. The end of the support rod 32 away from the support frame 31 abuts against the outer wall of the storage shell 5. The elastic element includes fixed seats 36 fixedly installed on both sides of the rotating shell 4. A sliding groove 37 is provided on the positioning seat 29. A sliding plate 38 is slidably provided in the sliding groove 37. One end of the sliding plate 38 is fixedly connected to the fixed seat 36. The other end of the sliding plate 38 is connected to the inner wall of the sliding groove 37 by several second compression springs 39. A second movable seat 41 is provided on the side of the rotating shell 4 away from the moving mold 3. Several second ejection rods 42 are fixedly connected on the second movable seat 41. The second ejection rods 42 pass through the rotating shell 4, the storage shell 5 and the support seat 6 respectively. Second support columns 45 are fixedly connected on both sides of the second movable seat 41. A third fixed column 43 is fixedly connected on the second support column 45. One end of the third fixed column 43 is fixedly connected to the outer wall of the rotating shell 4. A fixed plate 44 is fixedly connected to the other end of the third fixed column 43. Two support blocks 46 adapted to the second support columns 45 are fixedly connected to the top of the casting table 1. The tension spring 35 is initially in a stretched state, applying tension to the support frame 31 and support rod 32 so that the support rod 32 abuts against the outer wall of the housing 5. When the position adjustment unit drives the housing 5 to move towards the moving mold 3, the tension spring 35 drives the support frame 31 and support rod 32 to move synchronously with the housing 5. The support frame 31 moves towards the movable column 30, and the movable column 30 contacts the inclined surface on the support frame 31. As the support frame 31 continues to translate, the support frame 31 pushes the movable column 30 and the positioning seat 29 to slide relative to the slide plate 38. The second compression spring 39 is in a compressed state, increasing the distance between the two positioning seats 29, and the housing 5 and the clearance hole 40 slide relative to the positioning seats 29. When the ejection mechanism pushes the casting into the housing 5 and is supported by the support seat 6, the casting is located between the two positioning seats 29. The ejection mechanism continues to push the casting, support seat 6, and housing 5 to slide relative to the rotating shell 4. When the housing shell 5 is reset, the housing shell 5 pushes the support rod 32 and the support frame 31 to move in the opposite direction to the rotating shell 4. The inclined surface on the support frame 31 no longer supports the movable column 30. The second compression spring 39 drives the positioning seat 29 to move toward the casting. Finally, the two positioning seats 29 clamp the casting, thereby limiting the position of the casting. During the process of the rotating shell 4 rotating to below the moving mold 3, the rotating shell 4 drives the second support column 45 to move toward the support block 46. When the second support column 45 and the support block 46 come into contact, as the rotating shell 4 continues to rotate, the support block 46 pushes the second support column 45 to slide relative to the third fixed column 43. The second ejection rod 42 slides relative to the support seat 6. The second ejection rod 42 pushes the casting located on the support seat 6 out of the housing shell 5, which facilitates heat dissipation of the casting and makes it convenient for the operator to remove the casting. The design of the fixed plate 44 prevents the second support column 45 from slipping off the third fixed column 43.
