Description

Technical Field

[0001] This invention relates to the field of aluminum alloy casting technology, and in particular to a GIS-type split casting and forming equipment for irregular aluminum alloys. Background Technology

[0002] Gas-insulated metal-enclosed switchgear (GIS) is used in high-voltage power systems. Its housing and internal structural components are mostly irregularly shaped aluminum alloy castings, which are usually produced by a split-type metal mold casting process. During the split casting process, due to the complex shape, uneven wall thickness, internal cavity, side hole and sealing flange of the gas-insulated metal-enclosed switch castings, multiple treatments are required for the parting surface of the upper and lower molds, such as blowing, spraying and demolding, and rapid drying.

[0003] In the prior art, such as the patent with publication number CN120095124A, a high-performance aluminum alloy casting and forming equipment and its usage method are disclosed.

The composite nozzle can switch between compressed air mode, hot air mode, or mold release agent mode.

[0007] Preferably, the path moving structure includes a fixed plate frame fixedly installed inside the housing, and a moving rod extends through one side of the housing; A gear column is rotatably mounted at the center of the fixed plate frame. A sleeve plate is sleeved on the outside of the gear column, and a toothed plate meshes with the outside of the gear column. The toothed plate is slidably mounted inside the sleeve plate. A rocker arm is movably connected to one end of the toothed plate. A servo motor is fixedly mounted on the inner wall of the housing, and the output end of the servo motor is fixedly connected to the other end of the rocker arm. The fixed plate frame has a U-shaped groove inside, the gear column passes through the inside of the fixed plate frame, and a rotating rod is fixedly installed at the end of the gear column. The rotating rod has a sliding hole inside, and an insert rod is fixedly installed between the rotating rod and the moving rod.

[0008] Preferably, the gear column and the rotating rod are coaxially arranged, and the bottom of the fixed plate frame is provided with a sliding groove for the sliding rod to slide, and a moving block is provided inside the sliding groove.

[0009] Preferably, the composite nozzle includes a fixed head fixedly installed at the end of the movable rod, the fixed head having a cavity inside, a nozzle being movably connected inside the cavity, and an atomizing nozzle being fixedly installed on one side of the nozzle; The nozzle is connected to the air duct and the hot air duct, and springs are fixedly connected to both sides of the inner wall of the cavity; A vacuum generator is provided at the top of the fixed head, and a funnel is fixedly installed on the outside of the vacuum generator.

[0010] Preferably, the nozzle is arranged in a concentric tube, and both the nozzle and the atomizing nozzle are located inside the cavity.

[0011] Preferably, the air pipeline includes an air cylinder fixedly installed on one side of the housing, an air compressor is installed inside the air cylinder, a filter is installed at the inlet of the air compressor, a pressure regulating valve is installed at the outlet of the air compressor, and the pressure regulating valve is connected to the nozzle. The hot air duct includes a hot air duct fixedly installed on one side of the housing, an electric heater is installed inside the hot air duct, and a temperature controller is connected to one side of the electric heater. The release agent pipeline includes a storage tank fixedly installed on one side of the shell, a delivery pump installed inside the storage tank, a pressure regulating valve installed at the outlet of the delivery pump, and the pressure regulating valve connected to the atomizing nozzle.

[0012] Preferably, the air duct, hot air duct, and release agent duct are all interconnected by pipes, and electrically controlled valves are installed on the pipes.

[0013] Preferably, the driving mold opening mechanism is either a hydraulic cylinder or a pneumatic cylinder, used to achieve segmented control of the mold opening speed.

[0014] A method for split casting of GIS irregular-shaped aluminum alloys, applied to the aforementioned GIS irregular-shaped aluminum alloy split casting equipment, includes the following steps: S101, Mold Opening Process: First, the mold opening mechanism is driven to open the upper mold relative to the lower mold to a set distance. Then, the composite nozzle is moved along the trajectory by the path moving structure to process the parting surface of the lower mold and the parting surface of the upper mold in sequence as follows: First processing: Switch to compressed air mode, and use high-speed airflow and negative pressure generated by vacuum generator to remove dust and residue from the upper and lower molds respectively; Second processing: Switch to release agent mode, and spray the release agent by atomizing it and then combining it with high-speed airflow. Third step: Switch to hot air mode to dry and cure the sprayed release agent; S102, Composite nozzle swing; When the path moving structure drives the composite nozzle to move along the trajectory, the airflow ejected from the composite nozzle pushes the composite nozzle to swing to one side. The composite nozzle is pushed back and passes the midpoint by the spring action. The inertia makes it continue to swing to the other side to achieve the swing. S103, Mold Closing: Drive the mold opening mechanism to move the upper mold downwards and close it with the lower mold to complete the mold closing; S104. Casting: Molten aluminum alloy is poured into the cavity of a split mold, and after pressure holding and solidification, an irregularly shaped casting is formed. S105, Mold Opening and Part Removal: Drive the mold opening mechanism again to open the upper mold, remove the casting, and return to step S for the next cycle.

[0015] Preferably, in step S104, low-pressure casting or gravity casting is used for pouring, the pouring temperature is controlled at 680℃~720℃, and the holding time is set to 30~180 seconds according to the wall thickness of the casting.

[0016] The beneficial effects of this invention are: The upper mold is opened upward by driving the mold opening mechanism to the set mold opening distance. After the mold is opened, the path moving structure drives the composite nozzle to start from the starting position, pass through the lower mold parting surface and the upper mold parting surface in sequence along the U-shaped trajectory, and then return. During the movement of the composite nozzle, the composite nozzle switches between compressed air mode, hot air mode, or mold release agent mode because the pipeline is connected to the composite nozzle. After the entire process is completed, the upper mold and lower mold close to perform casting and molding. This achieves unified treatment of all contact surfaces of the split mold, eliminates blind spots, and reduces human intervention by using compressed air mode, hot air mode, or mold release agent mode, thus greatly shortening the casting time of the entire mold.

[0020] 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.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a GIS-shaped aluminum alloy split casting molding equipment includes a housing 1, a split mold is provided on one side of the housing 1, the split mold includes an upper mold 2 and a lower mold 3, and a drive mold opening mechanism 8 is fixedly installed on the top of the housing 1 for driving the upper mold 2 to open or close relative to the lower mold 3. A composite nozzle 5 is provided on one side of the housing 1, and a path moving structure 4 is provided inside the housing 1. The path moving structure 4 can drive the composite nozzle 5 to move along the trajectory, so that the composite nozzle 5 passes through the parting surface of the lower mold 3 and the upper mold 2 in sequence for processing. The composite nozzle 5 is connected to a plurality of pipe components 6 on one side. The plurality of pipe components 6 include an air pipe 601, a hot air pipe 602 and a mold release agent pipe 603, wherein the composite nozzle 5 switches between compressed air mode, hot air mode or mold release agent mode.

[0022] In this embodiment, the mold opening mechanism 8 is driven to open the upper mold 2 upward to the set mold opening distance. After the mold is opened, the path moving structure 4 drives the composite nozzle 5 to start from the starting position, pass through the parting surface of the lower mold 3 and the parting surface of the upper mold 2 along the U-shaped trajectory, and then return. During the movement of the composite nozzle 5, since the pipeline 6 is connected to the composite nozzle 5, the composite nozzle 5 switches between compressed air mode, hot air mode, or release agent mode to perform purging, spraying release agent, or drying of release agent. After the entire process is completed, the upper mold 2 and the lower mold 3 close for casting and molding. The whole process achieves unified treatment of all contact surfaces of the split mold, eliminates blind spots in the treatment, and reduces human intervention by using compressed air mode, hot air mode, or release agent mode, greatly shortening the casting time of the entire mold.

[0023] As one implementation method, such as Figure 4 , Figure 5 and Figure 6 The path moving structure 4 shown includes a fixed plate frame 401 fixedly installed inside the housing 1, and a moving rod 402 passing through one side of the housing 1. A gear column 403 is rotatably mounted at the center of the fixed plate frame 401. A sleeve plate 407 is sleeved on the outside of the gear column 403, and a toothed plate 404 meshes on the outside of the gear column 403. The toothed plate 404 is slidably mounted inside the sleeve plate 407. A rocker arm 405 is movably connected to one end of the toothed plate 404. A servo motor 406 is fixedly mounted on the inner wall of the housing 1. The output end of the servo motor 406 is fixedly connected to the other end of the rocker arm 405. The fixed plate frame 401 has a U-shaped groove 408 inside, the gear column 403 passes through the inside of the fixed plate frame 401, and a rotating rod 409 is fixedly installed at the end of the gear column 403. The rotating rod 409 has a sliding hole inside, and an insert rod 410 is fixedly installed between the rotating rod 409 and the moving rod 402.

[0024] In this embodiment, the servo motor 406 drives the rocker arm 405 to rotate, and the rocker arm 405 pulls the gear plate 404 and the gear column 403 to rotate, moving repeatedly inside the sleeve plate 407. As a result, the gear column 403 rotates back and forth. When the gear column 403 drives the rotating rod 409 to move back and forth, due to the restriction of the U-shaped groove 408, the rotating rod 409 drives the moving rod 402 to move back and forth along the path of the U-shaped groove 408, thereby performing sequential operations to target the parting surface of the mold.

[0025] As one implementation method, such as Figure 3 , Figure 4 As shown, the gear column 403 and the rotating rod 409 are coaxially arranged. The bottom of the fixed plate frame 401 is provided with a sliding groove for the sliding rod 402 to slide, and a moving block 411 is provided inside the sliding groove.

[0026] In this embodiment, when the rotating rod 409 drives the moving rod 402 to move back and forth along the path of the U-shaped groove 408, the moving block 411 outside the moving rod 402 slides inside the groove, thereby improving the movement stability of the moving rod 402 in the upper mold 2 and the lower mold 3.

[0027] As one implementation method, such as Figure 6 As shown, the composite nozzle 5 includes a fixed head 501 fixedly installed at the end of the moving rod 402. The fixed head 501 has a cavity 502 inside, and a nozzle 503 is movably connected inside the cavity 502. An atomizing nozzle 504 is fixedly installed on one side of the nozzle 503. The nozzle 503 is connected to the air pipe 601 and the hot air pipe 602, and springs 505 are fixedly connected to both sides of the inner wall of the cavity 502. A vacuum generator 506 is provided at the top of the fixed head 501, and a funnel 507 is fixedly installed on the outside of the vacuum generator 506.

[0028] In this embodiment, when the nozzle 503 sprays air, the airflow back force pushes the nozzle 503 to swing to one side. When it swings to a certain angle, the spring 505 is compressed and stores elastic energy. After the force of the spring 505 exceeds the back force, the nozzle 503 is pushed back and passes the midpoint. Inertia causes it to continue to swing to the other side, realizing reciprocating swing. This can cope with the covering during the blowing and spraying process, avoid the omission of complex curved surfaces in the mold, and adapt to split irregular molds with different shapes, depths and angles.

[0029] As one implementation method, such as Figure 1 , Figure 2 and Figure 7 The nozzle 503 shown has a concentric tube arrangement inside, and both the nozzle 503 and the atomizing nozzle 504 are located inside the cavity 502.

[0030] In this embodiment, a concentric arrangement is used so that when compressed air is ejected at high speed, a low-pressure zone is formed at the outlet, which entrains the surrounding hot air and achieves mixing.

[0031] As one implementation method, such as Figure 1 , Figure 2 and Figure 7 As shown, the air pipeline 601 includes an air cylinder 607 fixedly installed on one side of the housing 1. An air compressor 608 is installed inside the air cylinder 607. A filter 609 is installed at the inlet of the air compressor 608. A pressure regulating valve 610 is installed at the outlet of the air compressor 608. The pressure regulating valve 610 is connected to the nozzle 503. The hot air duct 602 includes a hot air duct 611 fixedly installed on one side of the housing 1. An electric heater 612 is installed inside the hot air duct 611, and a temperature controller 613 is connected to one side of the electric heater 612. The mold release agent pipeline 603 includes a storage tank 604 fixedly installed on one side of the housing 1. A delivery pump 605 is installed inside the storage tank 604. A pressure regulating valve 606 is installed at the outlet of the delivery pump 605. The pressure regulating valve 606 is connected to the atomizing nozzle 504.

[0032] In this embodiment, after the air pipe 601 is connected, the nozzle 503, in cooperation with the path moving structure 4, blows a full-coverage cleaning of the parting surface of the lower mold 3 and the parting surface of the upper mold 2. After the release agent mode is activated, the air pipe 601 is cut off, the moving speed of the path moving structure 4 is reduced, and the release agent in the storage tank 604 is sucked in through the atomizing nozzle 504. With the cooperation of the composite nozzle 5, the complex curved surface is fully covered. After spraying, the hot air pipe 602 and the air pipe 601 are connected. Hot air is blown evenly onto the parting surface and sides of the mold release agent to make the mold release agent dry quickly. The temperature controller 613 monitors the outlet temperature in real time. When the temperature exceeds the limit, the electric heater 612 is automatically cut off and an alarm is triggered.

[0033] As one implementation method, such as Figure 1 , Figure 2 and Figure 3 As shown, the air duct 601, hot air duct 602 and mold release agent duct 603 are all interconnected by pipes, and electrically controlled valves are installed on the pipes.

[0034] Among them, the mold opening mechanism 8 is either a hydraulic cylinder or a pneumatic cylinder, used to achieve segmented control of the mold opening speed.

[0035] This specification also provides an embodiment of a GIS irregular-shaped aluminum alloy split casting molding method, including the following steps: S101, Mold Opening Process: First, the mold opening mechanism 8 is activated to open the upper mold 2 relative to the lower mold 3 upwards to a set distance. Then, the composite nozzle 5 is moved along the trajectory by the path moving structure 4, and the parting surface of the lower mold 3 and the parting surface of the upper mold 2 are processed in sequence as follows: First processing: Switch to compressed air mode, and use high-speed airflow and negative pressure generated by vacuum generator 506 to remove dust and residue from upper mold 2 and lower mold 3 respectively; Second processing: Switch to release agent mode, and spray the release agent by atomizing it and then combining it with high-speed airflow. Third step: Switch to hot air mode to dry and cure the sprayed release agent; S102, Composite nozzle 5 swings; When the path moving structure 4 drives the composite nozzle 5 to move along the trajectory, the airflow ejected by the composite nozzle 5 pushes the composite nozzle 5 to swing to one side. Using the action of spring 505, the composite nozzle 5 is pushed back and passes the midpoint. Inertia makes it continue to swing to the other side to achieve swinging. S103, Mold closing: Drive the mold opening mechanism 8 to move the upper mold 2 downward and close it with the lower mold 3 to complete the mold closing; S104. Casting: Molten aluminum alloy is poured into the cavity of a split mold, and after pressure holding and solidification, an irregularly shaped casting is formed. S105, Mold opening and part removal: Drive the mold opening mechanism 8 again to open the upper mold 2, remove the casting, and return to step S101 for the next cycle.

[0036] In step S104, low-pressure casting or gravity casting is used for pouring, the pouring temperature is controlled at 680℃~720℃, and the holding time is set to 30~180 seconds according to the wall thickness of the casting.
