Description

Technical Field

[0001] This invention relates to the field of fixed-point casting technology, and in particular to a furnace tilting fixed-point casting device for a large vacuum induction furnace. Background Technology

[0002] Large vacuum induction furnaces are key equipment in the metallurgical industry for melting special metal materials. They are widely used in aerospace, nuclear power, and high-end equipment manufacturing. After melting metals in a vacuum environment, the molten metal in the furnace is usually poured into specific molds to form the desired castings or ingots. With the increasing demands of industry for casting quality, production efficiency, and automation, precise control of the casting process has become a crucial factor affecting product quality and production safety.

[0003] Currently, casting operations in large vacuum induction furnaces mostly employ a tilting casting method. This involves a drive mechanism that rotates the furnace around a specific axis, pouring the molten metal into a casting mold below. However, existing tilting casting devices suffer from several problems in practical applications: First, the positioning accuracy during casting is insufficient. Traditional tilting mechanisms typically have only a single rotational fulcrum. During the tilting process, the trajectory of the molten metal outlet is complex, making it difficult to accurately align with the pouring gate of the casting mold. This can easily lead to molten metal splashing or mold misalignment, affecting the quality of the casting and even causing safety accidents. Second, the connection between casting and mold transport is not sufficiently automated. In existing equipment, the positioning and transport of the casting mold largely rely on manual assistance or simple transport tracks, making it difficult to... The lack of automatic mold placement and automatic removal after casting results in discontinuous work cycles and low production efficiency. Third, furnace cleaning is difficult. After casting, molten metal slag and oxides often remain on the furnace walls. If not cleaned promptly, this will affect the purity of the metal in the next batch. Traditional methods often involve manual cleaning or separate cleaning equipment, which is cumbersome and requires interrupting the production process, making it difficult to quickly and automatically clean the furnace interior after casting. Fourth, the coordination between casting and slag removal is poor. The molten metal generated during casting and the slag removed after casting need to be collected separately. However, existing equipment typically lacks the ability to alternate between casting and slag removal at the same station, leading to low equipment utilization or the need for additional transfer procedures.

[0004] To address the aforementioned issues, there is an urgent need to develop a comprehensive casting device that can achieve precise tilting and fixed-point casting in large vacuum induction furnaces, and integrate automatic mold conveying, automatic furnace cleaning, and automatic slag collection, in order to improve the automation level of casting operations and the stability of product quality. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention adopts the following technical solution: a furnace tilting and fixed-point casting device for a large vacuum induction furnace, comprising a working mechanism for fixed-point casting, the working mechanism comprising a fixed base and a metal furnace, and a feeding mechanism for feeding a mold in and a cleaning mechanism for cleaning the interior of the metal furnace, the cleaning mechanism comprising a cleaning support.

[0006] Furthermore, the working mechanism also includes upper side columns fixedly installed on both sides of the upper end of the metal furnace, lower side columns fixedly installed at both ends of the middle part of the metal furnace, two protruding side plates fixedly installed on the fixed base, a lower placement support and an upper placement support fixedly installed on the protruding side plates, and a base foot fixedly installed at the bottom of the metal furnace. In the initial state, the base foot is in contact with the fixed base, and the lower side column is located in the lower placement support.

[0007] Furthermore, the working mechanism also includes a winch drum rotatably installed in a fixed base, with a steel wire rope wound on the winch drum, and a bottom protrusion fixedly installed at the bottom of the metal furnace, with the end of the steel wire rope fixedly installed to the bottom protrusion.

[0008] Furthermore, the working mechanism also includes a hydraulic press and a hydraulic motor fixedly installed on a fixed base. The hydraulic press is provided with an oil outlet pipe, the hydraulic motor is provided with a connecting pipe, and the hydraulic motor is provided with a return oil pipe. The return oil pipe is connected to the hydraulic press, and the hydraulic press drives the winch drum to rotate.

[0009] The metal furnace contains molten metal for casting. Initially, the base is in contact with the fixed base, and the metal furnace is in a vertical position. When the valve is opened, the hydraulic press sends oil through the outlet pipe into the connecting pipe, and then the oil enters the hydraulic motor. Subsequently, the oil flows back to the hydraulic press through the return pipe, forming an oil circulation. The hydraulic motor drives the winch to rotate, and the winch pulls the bottom protrusion upward through the wire rope, causing the metal furnace to rotate clockwise around the lower support via the lower side column until the upper side column reaches the upper support. Then, the wire rope continues to pull the bottom protrusion upward, causing the lower side column to detach from the lower support. The metal furnace then rotates clockwise around the upper support via the upper side column, causing the molten metal in the metal furnace to be poured into the casting mold for casting.

[0010] After casting is completed, the winch releases the wire rope. Under the action of gravity, the metal furnace first rotates relative to the upper support via the upper side column, causing the metal furnace to rotate counterclockwise around the upper support via the upper side column. Then the lower side column enters the lower support. At this time, the upper side column is located in the upper support and the lower column is located in the lower support.

[0011] Furthermore, the feeding mechanism includes a conveying frame, a conveying guide rail fixedly mounted on the conveying frame, a fixed rack fixedly mounted on the conveying frame, a front support plate and a rear support plate slidably mounted on the conveying guide rail, a moving motor fixedly mounted on both the front support plate and the rear support plate, a moving gear fixedly mounted on the motor shaft of the moving motor, and the moving gear meshing with the fixed rack.

[0012] Furthermore, each of the front and rear support plates is provided with a placement module. The placement module includes a lower sliding column slidably mounted on the front or rear support plate, a placement tray fixedly mounted on the lower sliding column, and a sliding column spring between the placement tray and the front or rear support plate. A casting mold is placed on the placement tray of the placement module on the front support plate, and a liquid receiving cylinder is placed on the placement tray of the placement module on the rear support plate.

[0013] Furthermore, each of the conveyor frame and the cleaning support is equipped with a trigger module. The trigger module includes a side fixing plate fixedly installed on the conveyor frame or the cleaning support. A lifting frame is slidably installed on the side fixing plate. A lifting guide column is fixedly installed on the lifting frame. The lifting frame is slidably installed with the conveyor frame or the cleaning support. A guide column spring is provided between the lifting frame and the conveyor frame or the cleaning support. A short rotating rod is rotatably installed on the side fixing plate. A long rotating rod is rotatably installed on the short rotating rod. The lifting frame is located above the short rotating rod. An upper rotating rod is rotatably installed on the long rotating rod. An upper roller is rotatably installed on the upper rotating rod. A mating gear is fixedly installed on the upper rotating rod. The mating gear is rotatably installed with the side fixing plate. A bottom roller is rotatably installed on the top of the lifting frame. A fixed slider is fixedly installed on the side fixing plate. A horizontal sliding column is slidably installed inside the fixed slider. A sliding rack is fixedly installed on the horizontal sliding column. The sliding rack is slidably installed with the fixed slider. The sliding rack meshes with the mating gear. A horizontal spring is provided between the horizontal sliding column and the side fixing plate. A distance sensor is fixedly installed inside the side fixing plate.

[0014] Furthermore, a valve is fixedly installed on the side fixing plate of the trigger module located on the conveyor frame. The valve is connected to the oil outlet pipe, the valve is connected to the connecting pipe, and the distance sensor is electrically connected to the valve.

[0015] The moving motor drives the moving gear to rotate. The moving gear meshes with the fixed rack, enabling the front and rear pallets to slide along the conveyor guide rail. When the front pallet moves to contact the upper roller of the trigger module located on the conveyor frame, the bottom roller is located below the placement tray. The upper rotating rod and the docking gear rotate a short distance clockwise relative to the side fixed plate. At this time, the upper roller pulls the long rotating rod to rotate, blocking the front pallet from moving forward. The moving motor stops rotating. At this time, the distance sensor detects the displacement of the long rotating rod and controls the valve to open, so that the oil outlet pipe and the connecting pipe are connected. The rotation of the docking gear drives the sliding rack and the horizontal sliding column to slide along the fixed slider, and the horizontal spring is compressed.

[0016] As molten metal enters the casting mold, its weight increases, causing the placement tray and lower sliding column to descend. The sliding column spring is compressed. When the placement tray presses down on the bottom roller, the lifting frame and lifting guide column descend, compressing the guide column spring. The lifting frame drives the short and long rotating rods to descend. The distance sensor detects that the long rotating rod is descending further. At this time, the winch drives the metal furnace to rotate counterclockwise, and the long rotating rod drives the upper rotating rod to continue rotating clockwise, causing the upper roller to descend. The horizontal spring is further compressed. When the upper roller descends below the lower surface of the front support plate, the moving motor rotates, driving the moving gear to rotate, allowing the front support plate to pass through the upper roller. After the front support plate has completely passed through the upper roller, the horizontal sliding column and guide column springs reset, causing the bottom roller and upper roller to return to their initial positions. The front support plate will not contact the upper roller of the trigger module on the cleaning bracket during movement.

[0017] Then the rear support plate moves to contact the upper roller of the trigger module on the cleaning bracket. When the upper roller of the trigger module is pushed, the upper rotating rod rotates, which in turn drives the long rotating rod to rotate. After the distance sensor detects that the long rotating rod has descended, the cleaning electric cylinder and the cleaning motor start, and the moving motor on the rear support plate stops rotating.

[0018] Furthermore, the cleaning mechanism includes an upper fixed block fixedly mounted on a cleaning bracket, a cleaning electric cylinder fixedly mounted on the upper fixed block, a telescopic plate fixedly mounted on the output end of the cleaning electric cylinder, an upper sliding column fixedly mounted on the telescopic plate, the upper sliding column being slidably mounted with the upper fixed block, a cleaning motor fixedly mounted on the telescopic plate, a cleaning shaft rotatably mounted on the telescopic plate, a cleaning gear fixedly mounted on the cleaning shaft, the cleaning motor driving the cleaning gear and the cleaning shaft to rotate through gear transmission, and a cleaning brush fixedly mounted on the cleaning shaft.

[0019] The cleaning cylinder extends, causing the telescopic plate and upper sliding column to move outward. The cleaning motor drives the cleaning gear, cleaning shaft, and cleaning brush to rotate. The cleaning brush extends into the metal furnace to clean it. After cleaning, the cleaning cylinder retracts, and the winch rotates the metal furnace clockwise, pouring the residue into the receiving cylinder. The metal furnace then returns to its initial vertical position. Because the spring force of the sliding column spring on the rear support plate is much smaller than that on the front support plate, when the waste enters the receiving cylinder, it will press down the lifting frame. Similarly, the upper roller then descends below the rear support plate. The rear support plate then passes the upper roller. When the rear support plate moves, it will not contact the upper roller of the trigger module on the conveying frame. This process is repeated to first cast the casting mold, and then collect the residue through the receiving cylinder.

[0020] The beneficial effects of this invention compared with the prior art are: (1) This invention sets a lower placement tray and an upper placement tray on a fixed base. The metal furnace rotates around two different fulcrums by the lower and upper side columns respectively. First, it tilts around the lower placement tray to a certain angle, and then continues to tilt around the upper placement tray. This double-fulcrum tilting trajectory enables the furnace outlet to be accurately aligned with the pouring position of the casting mold, avoiding metal splashing or deviation, and improving the casting positioning accuracy and casting quality; (2) This invention uses a trigger module on the conveyor frame to cooperate with the front support plate. When the casting mold moves to the designated position with the front support plate, the upper roller is pushed. After the distance sensor detects the displacement, the valve is automatically opened, thereby starting the hydraulic motor to drive the winch drum, so that the metal furnace automatically tilts and pours. After the pouring is completed, as the weight of the mold increases, the placement tray descends, triggering the upper roller to descend and reset, and the front support plate is automatically moved out, realizing a fully automatic process of pouring when the mold is in place and sending out when the pouring is completed; (3) This invention sets a liquid receiving cylinder on the rear support plate. And a cleaning cylinder, a cleaning motor and a cleaning brush are installed on the cleaning bracket. When the rear support plate moves to the cleaning station, the distance sensor on the cleaning bracket is triggered and the cleaning brush automatically extends into the metal furnace for rotation and cleaning. After cleaning, the furnace is tilted again to pour the internal residue into the receiving cylinder. This structure enables the furnace body cleaning and slag recycling after casting to be completed automatically. (4) In the placement module on the front support plate and the rear support plate of the present invention, the elastic force of the sliding column spring is set differently. The elastic force on the rear support plate is much smaller than that on the front support plate. When the molten metal is injected into the casting mold, the front support plate spring is compressed but will not trigger the upper roller to fall completely too early. When a small amount of waste slag enters the receiving cylinder, the rear support plate spring is easily compressed, causing the upper roller to fall quickly, ensuring that the rear support plate passes smoothly through the trigger module. At the same time, the front support plate will not trigger the upper roller on the cleaning bracket when it moves, and the rear support plate will not trigger the upper roller on the conveying frame when it moves, ensuring that the casting operation and the slag cleaning operation are carried out sequentially on the same conveying line and do not interfere with each other.

Detailed Implementation

[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0033] Example: Reference Figures 1-10A furnace tilting and fixed-point casting device for a large vacuum induction furnace includes a working mechanism for fixed-point casting. The working mechanism includes a fixed base 101 and a metal furnace 103. A feeding mechanism for feeding the mold and a cleaning mechanism for cleaning the inside of the metal furnace 103 are provided next to the working mechanism. The cleaning mechanism includes a cleaning bracket 301.

[0034] like Figures 2-5 As shown, the working mechanism also includes upper side columns 107 fixedly installed on both sides of the upper end of the metal furnace 103, lower side columns 105 fixedly installed at both ends of the middle part of the metal furnace 103, two protruding side plates 102 fixedly installed on the fixed base 101, and lower placement support 104 and upper placement support 106 fixedly installed on the protruding side plates 102. The bottom of the metal furnace 103 is fixedly installed with feet 111. In the initial state, the feet 111 are in contact with the fixed base 101, and the lower side columns 105 are located in the lower placement support 104.

[0035] like Figures 2-5 As shown, the working mechanism also includes a winch 108 rotatably installed in the fixed base 101, a wire rope 109 is wound on the winch 108, a bottom protrusion 110 is fixedly installed at the bottom of the metal furnace 103, and the end of the wire rope 109 is fixedly installed with the bottom protrusion 110.

[0036] like Figures 2-5 As shown, the working mechanism also includes a hydraulic press 112 and a hydraulic motor 115 fixedly installed on the fixed base 101. The hydraulic press 112 is provided with an oil outlet pipe 113, the hydraulic motor 115 is provided with a connecting pipe 114, and the hydraulic motor 115 is provided with a return oil pipe 116. The return oil pipe 116 is connected to the hydraulic press 112, and the hydraulic press 112 drives the winch drum 108 to rotate.

[0037] The metal furnace 103 contains molten metal for casting. Initially, the base 111 is in contact with the fixed base 101, and the metal furnace 103 is in a vertical position. When the valve 212 is opened, the hydraulic press 112 sends the molten metal through the outlet pipe 113 into the connecting pipe 114. The molten metal then enters the hydraulic motor 115, and subsequently flows back to the hydraulic press 112 through the return pipe 116, forming an oil circulation loop. The hydraulic motor 115 drives the winch drum 108 to rotate, and the winch drum 108 is connected by a wire rope 10... 9. Pull the bottom protrusion 110 upward, causing the metal furnace 103 to rotate clockwise around the lower support 104 via the lower side column 105 until the upper side column 107 reaches the upper support 106. Then, the wire rope 109 continues to pull the bottom protrusion 110 upward, causing the lower side column 105 to disengage from the lower support 104. The metal furnace 103 rotates clockwise around the upper support 106 via the upper side column 107, causing the molten metal in the metal furnace 103 to be poured into the casting mold 226 for casting.

[0038] After casting is completed, the winch 108 releases the wire rope 109. Under the action of gravity, the metal furnace 103 first rotates relative to the upper support 106 via the upper side column 107, so that the metal furnace 103 rotates counterclockwise around the upper support 106 via the upper side column 107. Then the lower side column 105 enters the lower support 104. At this time, the upper side column 107 is located in the upper support 106, and the lower side column 105 is located in the lower support 104.

[0039] like Figures 6-8 As shown, the feeding mechanism includes a conveying frame 201, a conveying guide rail 211 fixedly mounted on the conveying frame 201, a fixed rack 202 fixedly mounted on the conveying frame 201, a front support plate 203 and a rear support plate 228 slidably mounted on the conveying guide rail 211, a moving motor 204 fixedly mounted on both the front support plate 203 and the rear support plate 228, a moving gear 210 fixedly mounted on the motor shaft of the moving motor 204, and the moving gear 210 meshing with the fixed rack 202.

[0040] like Figures 6-8 As shown, a placement module is provided on the front support plate 203 and the rear support plate 228. The placement module includes a lower slide column 207 that is slidably installed on the front support plate 203 or the rear support plate 228. A placement tray 206 is fixedly installed on the lower slide column 207. A slide column spring 208 is provided between the placement tray 206 and the front support plate 203 or the rear support plate 228. A casting mold 226 is placed on the placement tray 206 of the placement module on the front support plate 203, and a liquid receiving cylinder 205 is placed on the placement tray 206 of the placement module on the rear support plate 228.

[0041] like Figures 6-8As shown, each of the conveyor frame 201 and the cleaning bracket 301 is equipped with a trigger module. The trigger module includes a side fixing plate 209 fixedly installed on the conveyor frame 201 or the cleaning bracket 301. A lifting frame 213 is slidably installed on the side fixing plate 209, and a lifting guide column 215 is fixedly installed on the lifting frame 213. The lifting frame 213 is slidably installed with the conveyor frame 201 or the cleaning bracket 301. A guide column spring 216 is provided between the lifting frame 213 and the conveyor frame 201 or the cleaning bracket 301. A short rotating rod 217 is rotatably installed on the side fixing plate 209, and a long rotating rod 218 is rotatably installed on the short rotating rod 217. The lifting frame 213 is located above the short rotating rod 217, and a long rotating rod 218 is rotatably installed on the long rotating rod 218. The system includes an upper rotating rod 220, on which an upper roller 221 is rotatably mounted. A mating gear 227 is fixedly mounted on the upper rotating rod 220 and is rotatably mounted to a side fixing plate 209. A bottom roller 214 is rotatably mounted on the top of the lifting frame 213. A fixed slider 222 is fixedly mounted on the side fixing plate 209. A horizontal sliding column 224 is slidably mounted inside the fixed slider 222. A sliding rack 223 is fixedly mounted on the horizontal sliding column 224 and is slidably mounted to the fixed slider 222. The sliding rack 223 meshes with the mating gear 227. A horizontal spring 225 is provided between the horizontal sliding column 224 and the side fixing plate 209. A distance sensor 219 is fixedly mounted inside the side fixing plate 209.

[0042] like Figures 6-8 As shown, a valve 212 is fixedly installed on the side fixing plate 209 of the trigger module located on the conveyor frame 201. The valve 212 is connected to the oil outlet pipe 113 and the connecting pipe 114. The distance sensor 219 is electrically connected to the valve 212.

[0043] The moving motor 204 drives the moving gear 210 to rotate. The moving gear 210, through meshing with the fixed rack 202, enables the front support plate 203 and the rear support plate 228 to slide along the conveyor guide rail 211. When the front support plate 203 moves to contact the upper roller 221 of the trigger module located on the conveyor frame 201, the bottom roller 214 is positioned below the placement tray 206. The upper rotating rod 220 and the mating gear 227 rotate a short distance clockwise relative to the side fixed plate 209. When the upper roller 221 pulls the long rotating rod 218 to rotate, the upper roller 221 blocks the front support plate 203 from moving forward. At this time, the moving motor 204 stops rotating. At this time, the distance sensor 219 detects the displacement of the long rotating rod 218 and controls the valve 212 to open, so that the oil outlet pipe 113 and the connecting pipe 114 are connected. The mating gear 227 rotates, driving the sliding rack 223 and the horizontal sliding column 224 to slide along the fixed slider 222, and the horizontal spring 225 is compressed.

[0044] As the molten metal enters the casting mold 226, its weight increases, causing the placement tray 206 and the lower sliding column 207 to descend. The sliding column spring 208 is compressed. When the placement tray 206 presses down the bottom roller 214, the lifting frame 213 and the lifting guide column 215 descend, compressing the guide column spring 216. The lifting frame 213 drives the short rotating rod 217 and the long rotating rod 218 to descend. The distance sensor 219 detects that the long rotating rod 218 descends further. At this time, the winch drum 108 drives the metal furnace 103 to rotate counterclockwise, and the long rotating rod 218 drives the upper... The rotating rod 220 continues to rotate clockwise, causing the upper roller 221 to descend and the horizontal spring 225 to be further compressed. When the upper roller 221 descends below the lower surface of the front support plate 203, the moving motor 204 rotates, driving the moving gear 210 to rotate, so that the front support plate 203 passes the upper roller 221. After the front support plate 203 has completely passed the upper roller 221, the horizontal sliding column 224 and the guide column spring 216 reset, so that the bottom roller 214 and the upper roller 221 return to their initial positions. The front support plate 203 will not contact the upper roller 221 of the trigger module on the cleaning bracket 301 when it moves.

[0045] Subsequently, the rear support plate 228 moves to contact the upper roller 221 of the trigger module on the cleaning bracket 301. When the upper roller 221 of the trigger module is pushed, the upper rotating rod 220 rotates, causing the long rotating rod 218 to rotate. After the distance sensor 219 detects that the long rotating rod 218 has descended, the cleaning electric cylinder 303 and the cleaning motor 305 start, and the moving motor 204 on the rear support plate 228 stops rotating.

[0046] like Figure 9 , Figure 10 As shown, the cleaning mechanism includes an upper fixing block 302 fixedly mounted on a cleaning bracket 301. A cleaning electric cylinder 303 is fixedly mounted on the upper fixing block 302. A telescopic plate 309 is fixedly mounted on the output end of the cleaning electric cylinder 303. An upper sliding column 304 is fixedly mounted on the telescopic plate 309. The upper sliding column 304 is slidably mounted with the upper fixing block 302. A cleaning motor 305 is fixedly mounted on the telescopic plate 309. A cleaning shaft 308 is rotatably mounted on the telescopic plate 309. A cleaning gear 306 is fixedly mounted on the cleaning shaft 308. The cleaning motor 305 drives the cleaning gear 306 and the cleaning shaft 308 to rotate through gear transmission. A cleaning brush 307 is fixedly mounted on the cleaning shaft 308.

[0047] The cleaning cylinder 303 extends, causing the telescopic plate 309 and the upper sliding column 304 to move outward. The cleaning motor 305 drives the cleaning gear 306, the cleaning shaft 308, and the cleaning brush 307 to rotate. The cleaning brush 307 extends into the metal furnace 103 to clean it. After cleaning, the cleaning cylinder 303 retracts, and the winch 108 drives the metal furnace 103 to rotate clockwise, pouring the residue inside the metal furnace 103 into the receiving cylinder 205. Then, the metal furnace 103 returns to its initial vertical position. The elastic force of the sliding spring 208 on the rear support plate 228 is much smaller than that of the sliding spring 208 on the front support plate 203. When the waste enters the liquid receiving cylinder 205, it will press down the lifting frame 213. Similarly, the upper roller 221 then descends below the rear support plate 228. The rear support plate 228 then passes through the upper roller 221. When the rear support plate 228 moves, it will not contact the upper roller 221 of the trigger module on the conveying frame 201. This process is repeated to first cast the casting mold 226, and then collect the residue through the liquid receiving cylinder 205.

[0048] Working principle: The moving motor 204 drives the moving gear 210 to rotate. The moving gear 210 meshes with the fixed rack 202, enabling the front support plate 203 and the rear support plate 228 to slide along the conveying guide rail 211. When the front support plate 203 moves to contact the upper roller 221 of the trigger module located on the conveying frame 201, the bottom roller 214 is located below the placement tray 206. The upper rotating rod 220 and the docking gear 227 rotate a small section clockwise relative to the side fixed plate 209. At this time, the upper roller 221 pulls the long rotating rod 218 to rotate, and the upper roller 221 blocks the front support plate 203 from moving forward. At this time, the moving motor 204 stops rotating. At this time, the distance sensor 219 detects the displacement of the long rotating rod 218 and controls the valve 212 to open, so that the oil outlet pipe 113 and the connecting pipe 114 are connected. The mating gear 227 rotates, driving the sliding rack 223 and the horizontal sliding column 224 to slide along the fixed slider 222, and the horizontal spring 225 is compressed. The metal furnace 103 contains molten metal for casting. Initially, the base 111 is in contact with the fixed base 101, and the metal furnace 103 is in a vertical position. When the valve 212 is opened, the hydraulic press 112 sends the molten metal through the outlet pipe 113 into the connecting pipe 114. The molten metal then enters the hydraulic motor 115, and subsequently flows back to the hydraulic press 112 through the return pipe 116, forming an oil circulation loop. The hydraulic motor 115 drives the winch drum 108 to rotate, and the winch drum 108 is connected by a wire rope 10... 9. Pull the bottom protrusion 110 upward, causing the metal furnace 103 to rotate clockwise around the lower support 104 via the lower side column 105 until the upper side column 107 reaches the upper support 106. Then, the wire rope 109 continues to pull the bottom protrusion 110 upward, causing the lower side column 105 to disengage from the lower support 104. The metal furnace 103 rotates clockwise around the upper support 106 via the upper side column 107, causing the molten metal in the metal furnace 103 to be poured into the casting mold 226 for casting.

[0049] As the molten metal enters the casting mold 226, its weight increases, causing the placement tray 206 and the lower sliding column 207 to descend. The sliding column spring 208 is compressed. When the placement tray 206 presses down the bottom roller 214, the lifting frame 213 and the lifting guide column 215 descend, compressing the guide column spring 216. The lifting frame 213 drives the short rotating rod 217 and the long rotating rod 218 to descend. The distance sensor 219 detects that the long rotating rod 218 descends further. At this time, the winch drum 108 drives the metal furnace 103 to rotate counterclockwise, and the long rotating rod 218 drives the upper... The rotating rod 220 continues to rotate clockwise, causing the upper roller 221 to descend and the horizontal spring 225 to be further compressed. When the upper roller 221 descends below the lower surface of the front support plate 203, the moving motor 204 rotates, driving the moving gear 210 to rotate, so that the front support plate 203 passes the upper roller 221. After the front support plate 203 has completely passed the upper roller 221, the horizontal sliding column 224 and the guide column spring 216 reset, so that the bottom roller 214 and the upper roller 221 return to their initial positions. The front support plate 203 will not contact the upper roller 221 of the trigger module on the cleaning bracket 301 when it moves. After casting is completed, the winch 108 releases the wire rope 109. Under the action of gravity, the metal furnace 103 first rotates relative to the upper support 106 via the upper side column 107, so that the metal furnace 103 rotates counterclockwise around the upper support 106 via the upper side column 107. Then the lower side column 105 enters the lower support 104. At this time, the upper side column 107 is located in the upper support 106, and the lower side column 105 is located in the lower support 104.

[0050] Subsequently, the rear support plate 228 moves to contact the upper roller 221 of the trigger module on the cleaning bracket 301. When the upper roller 221 of the trigger module is pushed, the upper rotating rod 220 rotates, causing the long rotating rod 218 to rotate. After the distance sensor 219 detects that the long rotating rod 218 has descended, the cleaning electric cylinder 303 and the cleaning motor 305 start, and the moving motor 204 on the rear support plate 228 stops rotating. The cleaning cylinder 303 extends, causing the telescopic plate 309 and the upper sliding column 304 to move outward. The cleaning motor 305 drives the cleaning gear 306, the cleaning shaft 308, and the cleaning brush 307 to rotate. The cleaning brush 307 extends into the metal furnace 103 to clean it. After cleaning, the cleaning cylinder 303 retracts, and the winch 108 drives the metal furnace 103 to rotate clockwise, pouring the residue inside the metal furnace 103 into the receiving cylinder 205. Then, the metal furnace 103 returns to its initial vertical position. The elastic force of the sliding spring 208 on the rear support plate 228 is much smaller than that of the sliding spring 208 on the front support plate 203. When the waste enters the liquid receiving cylinder 205, it will press down the lifting frame 213. Similarly, the upper roller 221 then descends below the rear support plate 228. The rear support plate 228 then passes through the upper roller 221. When the rear support plate 228 moves, it will not contact the upper roller 221 of the trigger module on the conveying frame 201. This process is repeated to first cast the casting mold 226, and then collect the residue through the liquid receiving cylinder 205.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the present invention based on the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
