Description

Technical Field

[0001] This invention relates to the field of alloy casting technology, specifically a casting device for alloy materials. Background Technology

[0002] Alloy ingots are blocky metal semi-finished products with a certain shape formed by casting and solidification of alloy materials after melting. They are extremely important basic raw materials in industrial production. In the casting production process of high-quality alloy ingots (such as aluminum alloy ingots, aluminum-zinc alloy ingots, etc.), multi-channel casting technology is widely used to simultaneously inject molten alloy liquid into multiple casting mold cavities to improve production efficiency.

[0003] However, in existing casting equipment, a layer of slag composed of oxide inclusions, deoxidation products, and refractory material spallings often floats on the surface of the molten alloy during the casting process. This slag enters the casting system with the flow of molten metal. Once the slag enters the mold cavity, it not only reduces the quality of the casting but also easily clogs the casting nozzle. Currently, the traditional method of slag removal is mostly manual skimming. In the scenario of multi-channel simultaneous casting, it is difficult to achieve synchronous and efficient interception and removal of slag from each branch. At the same time, since the branches of multi-channel casting are interconnected, when the casting nozzle of one branch becomes blocked, it is often necessary to interrupt the entire casting operation. This not only reduces the continuous operating efficiency of the production line but also easily leads to the shutdown of the entire line due to local failures. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to avoid slag from entering the casting mold cavity and to quickly remove slag. To this end, a casting device for alloy materials is provided.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a casting device for alloy materials, comprising a driving mechanism, a ladle system, and a mold conveying system. The driving mechanism adopts a hydraulic tilting mechanism. The ladle system includes a fixed seat, the side end of which is connected to the working end of the driving mechanism. A ladle is disposed inside the fixed seat, the ladle being lined with refractory material. A cover plate is disposed on the ladle, and the cover plate is detachably connected to the ladle by bolts. A flow guide seat is disposed at the end of the ladle near the mold conveying system, and the flow guide seat is located away from the ladle. One end of the mold has several grooves, and each groove has a pouring nozzle at the end near the casting conveying system. Each groove also has a channel and isolation component at the end near the ladle. A separation module is located at the end of the cover plate near the grooves, with its working end extending into the guide seat. A slag discharge hole is located on the upper part of the guide seat, directly below the separation module. A waste bin is located at the end of the slag discharge hole furthest from the separation module. A sealing component is installed inside the slag discharge hole, normally closing it only when... The device is activated during slag removal. During casting, the drive mechanism tilts the ladle towards one side of the mold conveying system. The molten alloy liquid in the ladle first enters the guide seat, then flows through the separation module. The separation module intercepts the slag on the surface of the molten alloy liquid. The purified molten alloy liquid then flows into the groove through the channel and is discharged into the casting mold cavity on the mold conveying system through the nozzle. The molten alloy liquid is formed in the casting mold cavity. Compared with the current casting device, this invention effectively avoids slag flowing into each groove and even the casting mold cavity with the molten alloy liquid, solving the problem of slag removal being difficult to synchronize during multi-channel casting. In addition, each groove in this invention is equipped with a channel and an isolation component. The opening and closing of the channel is controlled by the isolation component, so that each casting branch can be independently controlled. When a nozzle is blocked or the casting mold malfunctions, the operator can cut off the molten alloy liquid supply to that branch through the corresponding isolation component without affecting the continuous operation of other casting branches. This effectively avoids the disadvantage of the entire line being shut down due to local failure and greatly improves the reliability of the production line.

[0006] Furthermore, the separation module includes a mounting base, a lifting frame, a second linear drive, and a first separation plate. The lifting frame is disposed within the mounting base, and the second linear drive is disposed above the mounting base. The working end of the second linear drive is connected to the lifting frame. The lifting frame contains a first chamber and a third chamber. One end of the first separation plate is disposed within the first chamber, and the other end is disposed within the guide seat. During the casting process, the first separation plate does not contact the bottom wall of the guide seat. The molten alloy flows through the area between the first separation plate and the bottom wall of the guide seat. The first separation plate centrally intercepts and removes slag from the surface of the molten alloy, significantly improving the quality of the finished casting during multi-cavity synchronous casting. Finally, the separation module also has an emergency handling function. When the drive mechanism malfunctions and causes the ladle to tilt and fail to return to its original position, the operator can activate the second linear drive to control the lifting frame and the first separation plate. The plate moves downward until its lower end abuts against the bottom wall of the guide seat. At this point, the first separation plate forms a physical barrier within the guide seat, preventing the molten alloy in the ladle from flowing into the groove and the nozzle through the channel. This effectively prevents continuous casting accidents caused by the drive mechanism failing to return to its original position and avoids the overflow of molten alloy from the casting mold cavity. Finally, a piston is installed in the third chamber of this invention. The piston and the third chamber are connected by a first compression spring. The first chamber and the third chamber are connected and filled with a transmission medium. A pressure detection element is installed at the end of the piston near the first compression spring. When the first separation plate abuts against the bottom wall of the guide seat, the first separation plate will squeeze the transmission medium in the first chamber into the third chamber. At this time, the piston compresses the first compression spring, and the pressure detection element generates an electrical signal and feeds it back to the control system, prompting the operator that the isolation is in place, thus preventing excessive driving force from damaging the first separation plate or the guide seat.

[0007] Furthermore, the separation module also includes a second separation plate, and a second chamber is provided inside the lifting frame. One end of the second separation plate is located inside the second chamber, and the other end of the second separation plate is located inside the guide seat. The second chamber is connected to the third chamber and is filled with a transmission medium. The distance between the second separation plate and the inner bottom wall of the guide seat is greater than the distance between the first separation plate and the inner bottom wall of the guide seat. During normal casting, the molten alloy liquid passes sequentially through the area between the second separation plate and the inner bottom wall of the guide seat, and then through the area between the first separation plate and the inner bottom wall of the guide seat. The first separation plate intercepts and removes the slag on the surface of the molten alloy liquid, while the second separation plate does not contact the molten alloy liquid. When the casting operation is completed, the operator can first start the second linear drive component, and then start the drive mechanism to control the ladle to tilt back to its original position. During operation, the second linear drive unit controls the lifting frame, the first separation plate, and the second separation plate to move downwards. The lower ends of the first and second separation plates will sequentially adhere to the inner bottom wall of the guide seat. At this time, the area between the first and second separation plates will be in an independent state. The operator can open the sealing component to open the slag discharge hole. The slag intercepted by the first separation plate and gathered between the first and second separation plates will fall into the waste bin under the action of gravity to achieve centralized collection. (To ensure the collection effect, the operator can also set up a blowing mechanism (such as an air gun) to assist the slag in entering the waste bin as needed.) After the slag collection is completed, the sealing component closes the slag discharge hole again. At the same time, the second linear drive unit controls the lifting frame, the first separation plate, and the second separation plate to move upwards to the initial position to facilitate the continued casting work of the subsequent casting mold.

[0008] Furthermore, the sealing assembly includes a sealing plate and a third linear drive component. The working end of the third linear drive component is connected to the sealing plate through a transmission component. When the casting device is in the casting state, the upper surface of the sealing plate and the inner bottom wall of the guide seat are in the same horizontal plane, that is, they are flush. When slag discharge is required, the third linear drive component drives the sealing plate to move downward through the transmission component, opening the slag discharge hole. At this time, the floating slag falls into the waste box with the help of gravity or auxiliary purging mechanism. After the slag discharge is completed, the sealing plate is reset to the flush position.

[0009] Furthermore, the transmission assembly includes a fixed sleeve and a connecting rod. A connecting sleeve is slidably installed inside the fixed sleeve, and a connecting block is slidably installed inside the connecting sleeve. One end of the connecting rod is connected to the sealing plate, and the other end of the connecting rod is connected to the connecting sleeve. The connecting block is connected to the working end of the third linear drive. The connecting block is connected to the connecting sleeve via a second compression spring. A pressure detection element two is provided at the end of the connecting block near the second compression spring. When the sealing plate moves upward under the drive of the third linear drive and abuts against the slag discharge hole, the upper surface of the sealing plate is flush with the inner bottom wall of the guide seat. At this time, the sealing plate is blocked by the guide seat and cannot continue to move upward, while the working end of the third linear drive continues to extend, forcing the connecting block to slide relative to the connecting sleeve and compress the second compression spring. The pressure detection element two detects the pressure value applied to the connecting block by the second compression spring in real time and transmits the pressure signal to the control system. The control system compares the pressure value fed back by the pressure detection element with the preset calibrated pressure threshold. If the measured pressure value reaches or exceeds the calibrated threshold, it indicates that the sealing plate has been tightly fitted with the inner bottom wall of the guide seat and the seal is reliable. If the measured pressure value is lower than the calibrated threshold, it is determined that the sealing plate is not fully in place. The control system then issues an alarm signal and prohibits the casting device from starting or performing the casting action, thereby avoiding a safety accident caused by the slag discharge hole not being properly sealed and the molten alloy liquid leaking into the waste box due to the insufficient stroke of the third linear drive component.

[0010] Furthermore, the transmission assembly also includes a positioning block and an electromagnet. The positioning block is mounted on the connecting rod, and the electromagnet is located inside the fixed sleeve near the sealing plate. The positioning block is made of ferromagnetic material. When the sealing plate enters the slag discharge hole under the drive of the third linear drive (the slag discharge hole is in a closed state), the electromagnet is energized to generate magnetic force and attract the positioning block, thereby keeping the connecting rod and the sealing plate in the current position. Through the above technical solution, it is avoided that the third linear drive will unexpectedly retract due to accidental pressure loss, gas interruption, or system failure during the casting process, so that the sealing plate will detach from the slag discharge hole. The positioning block and the electromagnet work together to achieve magnetic locking, preventing the slag discharge hole from opening accidentally.

[0011] Furthermore, the isolation component includes an isolation block and a first linear drive. The isolation block is positioned above the channel, and the first linear drive is positioned above the isolation block. The working end of the first linear drive is connected to the isolation block. During normal casting, the isolation block is positioned above the channel, and the channel remains open. When it is necessary to interrupt the connection between the channel and the groove, the control system sends a command to the first linear drive. The first linear drive pushes the isolation block down until its lower end completely closes the channel, thereby cutting off the flow of molten alloy from the ladle to the groove. Through the above technical solution, the operator can cut off or open the corresponding channel at any time according to the needs of the casting process, realizing precise on / off control of the casting flow rate, which facilitates quick adjustment of the liquid supply when changing the mold or in case of an emergency.

[0012] Furthermore, the nozzle includes a fixed shell, a movable shell, and a rotary drive component. The fixed shell is connected to the groove, and the movable shell is disposed on the fixed shell. The movable shell and the fixed shell are slidably sealed together. The rotary drive component is disposed on the side of the fixed shell, and its working end is connected to the movable shell. A liquid outlet is provided at the end of the movable shell away from the groove. During normal casting, the operator controls the ladle to tilt through the drive mechanism so that the molten alloy liquid is injected from the nozzle into the casting mold on the mold conveying system. When it is necessary to adjust the casting angle or align the gate position of different specifications of casting molds, the control system will drive the movable shell to rotate relative to the fixed shell through the rotary drive component, so that the liquid outlet is swung to the target angle on the preset trajectory, thereby precisely changing the outflow direction and landing position of the molten alloy liquid, thus ensuring that the alloy liquid is always accurately injected into the center of the casting mold pouring cup, avoiding problems such as metal splashing caused by gate offset.

[0013] Furthermore, the casting device also includes a monitoring system, which is located on the side of the mold conveying system away from the ladle system. The monitoring system collects data in real time on the quality of the casting mold, as well as the splashing of molten metal and the filling status inside the casting mold during casting. This allows the control system to adjust the tilting speed and tilting angle of the drive mechanism, the descent depth of the separation module, the rotation angle of the nozzle, or the opening timing of the isolation component according to the type of abnormality.

[0014] Furthermore, the transmission assembly also includes a positioning block and an electromagnet. The positioning block is fixedly mounted on the connecting rod. The electromagnet is located inside the fixed sleeve near the sealing plate. A movable block is located inside the positioning block near the electromagnet, and the movable block near the electromagnet is magnetic. A positioning pin is located inside the positioning block away from the electromagnet. The positioning pin is connected to the positioning block via a slider, a groove, and a return spring. A positioning hole is provided on the inner wall of the fixed sleeve, and the positioning hole cooperates with the positioning pin. The movable block near the positioning pin has a wedge-shaped structure, and the positioning pin near the movable block also has a wedge-shaped structure. When the electromagnet is energized, it generates a magnetic field that repels the movable block, causing the movable block to move away from the electromagnet. The moving block moves in the direction of the wedge-shaped surface, which slides relative to the wedge-shaped surface of the positioning pin. Through the oblique driving action of the wedge-shaped surface, the axial movement of the moving block is converted into the radial outward movement of the positioning pin. This pushes the positioning pin to overcome the elastic force of the return spring and extend it out of the positioning block, and finally lock it into the positioning hole set on the inner wall of the fixed sleeve, realizing the mechanical locking between the connecting rod and the fixed sleeve. When unlocking is required, the electromagnet is de-energized or energized in the reverse direction. Under the elastic force of the return spring, the positioning pin retracts from the positioning hole into the positioning block, and the moving block retracts in the direction of the electromagnet. Through the above technical solution, the self-locking ability and reliability of the transmission component are significantly improved, and the risk of the slag discharge through hole being opened due to the accidental retraction of the third linear drive component during the casting process is effectively avoided.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Compared with the existing casting devices, the present invention is equipped with a separation module, which can centrally intercept and remove the slag on the surface of the molten alloy liquid, effectively preventing the slag from flowing into various grooves or even the casting mold cavity with the molten metal. At the same time, the separation module also includes a second separation plate. During normal casting, the second separation plate does not come into contact with the molten metal, but during slag discharge, it works together with the first separation plate to form a closed chamber, so that the slag automatically falls into the waste bin under the action of gravity. This realizes online collection and automatic cleaning of slag, effectively solving the problem of slag removal being difficult to synchronize during multi-channel casting. In the present invention, each groove is equipped with a channel and an isolation component. The opening and closing of the channel is controlled by the isolation component, so that each casting branch can be independently controlled to control the on / off state. When a nozzle is blocked or When a casting mold malfunctions, the operator can cut off the supply of molten alloy to that branch using the corresponding isolation component without affecting the continuous operation of other casting branches. This effectively avoids production line shutdowns caused by localized faults. Finally, the invention also includes a transmission component and a sealing plate. The third linear drive unit drives the sealing plate to move up and down through the transmission component. In the casting state, the sealing plate is flush with the inner bottom wall of the guide seat, forming a continuous guide surface to facilitate smooth flow of molten metal. The transmission component has a magnetic or mechanical locking structure inside. During the casting process, the magnetic or mechanical locking structure effectively prevents the sealing plate from accidentally retracting, avoiding molten metal leakage accidents. This also effectively prevents the third linear drive unit from unexpectedly retracting due to accidental pressure loss, gas interruption, or system failure during the casting process, which could cause the sealing plate to detach from the slag discharge hole and lead to leakage.

[0018] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: As Figures 1-8As shown, the present invention provides a technical solution: a casting device for alloy materials, including a drive mechanism 1, a ladle system 2, and a mold conveying system 3. The drive mechanism 1 adopts a hydraulic tilting mechanism. The ladle system 2 includes a fixed seat 21, the side end of which is connected to the working end of the drive mechanism 1. A ladle 22 is disposed inside the fixed seat 21. The ladle 22 is lined with refractory material. A cover plate 23 is disposed on the ladle 22. The cover plate 23 is detachably connected to the ladle 22 by bolts. A guide seat 24 is disposed at the end of the ladle 22 near the mold conveying system 3. A plurality of grooves 244 are disposed at the end of the guide seat 24 away from the ladle 22. Each groove 244 is equipped with a pouring nozzle 26 at one end near the mold conveying system 3. Each groove 244 is equipped with a channel 243 and an isolation component at one end near the ladle 22. A separation module 25 is provided at one end of the cover plate 23 near the groove 244. The working end of the separation module 25 extends into the interior of the guide seat 24. A slag discharge hole is provided on the upper part of the guide seat 24. The slag discharge hole is located directly below the separation module 25. A waste bin 27 is provided at the end of the slag discharge hole away from the separation module 25. A sealing component is provided inside the slag discharge hole. The sealing component normally closes the slag discharge hole and only opens it during slag discharge. When casting is performed, the drive mechanism 1 drives the slag discharge hole. The ladle 22 is tilted towards one side of the mold conveying system 3. The molten alloy liquid in the ladle 22 first enters the guide seat 24, then flows through the separation module 25. The separation module 25 intercepts the scum on the surface of the molten alloy liquid. Then, the purified molten alloy liquid flows into the groove 244 through the channel 243. Finally, it is discharged into the casting mold cavity on the mold conveying system 3 through the nozzle 26. The molten alloy liquid is formed in the casting mold cavity. Compared with the current casting device, the present invention is equipped with a separation module 25, and multiple grooves 244 and corresponding nozzles 26 are provided on the guide seat 24. Through the above technical solution, scum is effectively avoided. As the molten alloy flows into each groove 244 and even into the casting mold cavity, the problem of slag removal being difficult to achieve synchronously during multi-channel casting is solved. In addition, each groove 244 in this invention is paired with a channel 243 and an isolation component. The opening and closing of the channel 243 is controlled by the isolation component, so that each casting branch can be independently controlled. When a nozzle 26 becomes blocked or the casting mold malfunctions, the operator can cut off the supply of molten alloy to that branch through the corresponding isolation component without affecting the continuous operation of other casting branches. This effectively avoids the drawback of the entire line being shut down due to local failure and greatly improves the reliability of the production line.

[0020] like Figures 2-5As shown, the separation module 25 includes a mounting base 251, a lifting frame 252, a second linear drive 253, and a first separation plate 254. The lifting frame 252 is disposed within the mounting base 251, and the second linear drive 253 is disposed above the mounting base 251. The working end of the second linear drive 253 is connected to the lifting frame 252 (the second linear drive 253 can be a servo electric cylinder or a servo pneumatic cylinder, etc.). The lifting frame 252 is provided with a first chamber 2521 and a third chamber 2523. One end of the first separation plate 254 is disposed within the first chamber 2521, and the other end of the first separation plate 254 is disposed within the first chamber 2521. Placed inside the guide seat 24, during the casting process, the first separation plate 254 does not contact the inner bottom wall of the guide seat 24. The molten alloy liquid passes through the area between the first separation plate 254 and the inner bottom wall of the guide seat 24. The first separation plate 254 centrally intercepts and removes the slag on the surface of the molten alloy liquid, significantly improving the quality of the finished castings during multi-cavity synchronous casting. Finally, the separation module 25 also has an emergency handling function. When the drive mechanism 1 malfunctions and causes the ladle 22 to tilt and fail to return to its original position, the operator can activate the second linear drive 253 to control the lifting frame 2. 52 and the first separation plate 254 move downwards until the lower end of the first separation plate 254 abuts against the inner bottom wall of the guide seat 24. At this time, the first separation plate 254 forms a physical partition in the guide seat 24, preventing the molten alloy liquid in the ladle 22 from flowing into the groove 244 and the nozzle 26 through the channel 243. This effectively prevents continuous casting accidents caused by the failure of the drive mechanism 1 to return to its original position, and avoids the overflow of molten alloy liquid from the casting mold cavity. Finally, in this invention, a piston 2524 is provided in the third chamber 2523. The piston 2524 and the third chamber 2523 are connected by a first compression spring. Chamber 2521 is connected to the third chamber 2523 and is filled with a transmission medium (such as hydraulic oil). A pressure detection element is provided at the end of piston 2524 near the first compression spring. When the first separation plate 254 abuts against the bottom wall of the guide seat 24, the first separation plate 254 will squeeze the transmission medium in the first chamber 2521 into the third chamber 2523. At this time, piston 2524 compresses the first compression spring, and pressure detection element 1 will generate an electrical signal and feed it back to the control system, prompting the operator that the isolation is in place, so as to avoid excessive driving force from damaging the first separation plate 254 or the guide seat 24.

[0021] like Figures 2-5As shown, the separation module 25 also includes a second separation plate 255, and a second chamber 2522 is also provided inside the lifting frame 252. One end of the second separation plate 255 is located in the second chamber 2522, and the other end of the second separation plate 255 is located in the guide seat 24. The second chamber 2522 is connected to the third chamber 2523 and is filled with a transmission medium. The distance between the second separation plate 255 and the inner bottom wall of the guide seat 24 is greater than the distance between the first separation plate 254 and the inner bottom wall of the guide seat 24. During normal casting operation... During the process, the molten alloy liquid sequentially passes through the area between the second separation plate 255 and the inner bottom wall of the guide seat 24, and the area between the first separation plate 254 and the inner bottom wall of the guide seat 24. The first separation plate 254 intercepts and removes slag from the surface of the molten alloy liquid, while the second separation plate 255 does not contact the molten alloy liquid. When the casting operation is completed, the operator can first activate the second linear drive component 253, and then activate the drive mechanism 1 to control the ladle 22 to tilt back to its original position. Upon startup, the second linear drive 253 controls the lifting frame 252, the first separation plate 254, and the second separation plate 255 to move downwards. The lower ends of the first separation plate 254 and the second separation plate 255 will sequentially adhere to the inner bottom wall of the guide seat 24. At this time, the area between the first separation plate 254 and the second separation plate 255 will be in an independent state. The operator can open the sealing component to open the slag discharge hole. The slag intercepted by the first separation plate 254 and gathered between the first separation plate 254 and the second separation plate 255 will fall into the waste box 27 under the action of gravity to achieve centralized collection (in order to ensure the collection effect, the operator can also set up a blowing mechanism (such as an air gun) to assist the slag in entering the waste box 27 as needed). After the slag collection is completed, the sealing component closes the slag discharge hole again. At the same time, the second linear drive 253 controls the lifting frame 252, the first separation plate 254, and the second separation plate 255 to move upwards to the initial position to facilitate the continued casting work of the subsequent casting mold.

[0022] like Figure 3 and Figure 6 As shown, the sealing assembly includes a sealing plate 271 and a third linear drive 272. The working end of the third linear drive 272 is connected to the sealing plate 271 through a transmission assembly. When the casting device is in the casting state, the upper surface of the sealing plate 271 and the inner bottom wall of the guide seat 24 are in the same horizontal plane, that is, they are flush. When slag discharge is required, the third linear drive 272 drives the sealing plate 271 to move downward through the transmission assembly, opening the slag discharge hole. At this time, the floating slag falls into the waste box 27 with the help of gravity or the auxiliary blowing mechanism. After the slag discharge is completed, the sealing plate 271 is reset to the flush position.

[0023] like Figure 6As shown, the transmission assembly includes a fixed sleeve 273 and a connecting rod 277. A connecting sleeve 274 is slidably installed inside the fixed sleeve 273, and a connecting block 275 is slidably installed inside the connecting sleeve 274. One end of the connecting rod 277 is connected to the sealing plate 271, and the other end of the connecting rod 277 is connected to the connecting sleeve 274. The connecting block 275 is connected to the working end of the third linear drive component 272. The connecting block 275 is connected to the connecting sleeve 274 through a second compression spring. A pressure detection element is provided at the end of the connecting block 275 near the second compression spring. When the sealing plate 271 is closed, the pressure detection element is activated. When the sealing plate 271 moves upward under the drive of the third linear drive 272 and abuts against the slag discharge through hole, the upper surface of the sealing plate 271 is flush with the inner bottom wall of the guide seat 24. At this time, the sealing plate 271 is blocked by the guide seat 24 and cannot continue to move upward, while the working end of the third linear drive 272 continues to extend, forcing the connecting block 275 to slide relative to the connecting sleeve 274 and compress the second compression spring. The pressure detection element 2 detects the pressure value applied by the second compression spring to the connecting block 275 in real time and transmits the pressure signal to the control system. The control system compares the pressure value fed back by the pressure detection element 2 with the preset calibrated pressure threshold. If the measured pressure value reaches or exceeds the calibrated threshold, it indicates that the sealing plate 271 is tightly fitted with the inner bottom wall of the guide seat 24 and the seal is reliable. If the measured pressure value is lower than the calibrated threshold, it is determined that the sealing plate 271 is not fully in place. The control system then issues an alarm signal and prohibits the casting device from starting or performing the casting action, thereby avoiding a safety accident caused by the slag discharge hole not being properly sealed and the molten alloy liquid leaking into the waste box 27 due to the insufficient stroke of the third linear drive component 272.

[0024] like Figure 6 As shown, the transmission assembly also includes a positioning block 276 and an electromagnet 278. The positioning block 276 is mounted on the connecting rod 277, and the electromagnet 278 is mounted inside the fixed sleeve 273 near the end of the sealing plate 271. The positioning block 276 is made of ferromagnetic material. When the sealing plate 271 enters the slag discharge through hole under the drive of the third linear drive 272 (the slag discharge through hole is in a closed state), the electromagnet 278 is energized to generate magnetic force and attract the positioning block 276, thereby keeping the connecting rod 277 together with the sealing plate 271 in the current position. Through the above technical solution, it is avoided that the third linear drive 272 will unexpectedly retract due to accidental pressure loss, gas interruption or system failure during the casting process, so that the sealing plate 271 will be separated from the slag discharge through hole. The positioning block 276 and the electromagnet 278 work together to achieve magnetic locking, preventing the slag discharge through hole from opening accidentally.

[0025] like Figure 3As shown, the isolation assembly includes an isolation block 241 and a first linear drive 242. The isolation block 241 is positioned above the channel 243, and the first linear drive 242 is positioned above the isolation block 241. The working end of the first linear drive 242 is connected to the isolation block 241. During normal casting, the isolation block 241 is positioned above the channel 243, and the channel 243 remains open. When it is necessary to interrupt the connection between the channel 243 and the groove 244, the control system sends a command to the first linear drive 242. The first linear drive 242 pushes the isolation block 241 down until its lower end completely closes the channel 243, thereby cutting off the flow of molten alloy from the ladle 22 to the groove 244. Through the above technical solution, the operator can cut off or open the corresponding channel 243 at any time according to the needs of the casting process, realize precise on / off control of the casting flow, and facilitate quick adjustment of the liquid supply when changing the mold or in case of an emergency.

[0026] like Figure 3 and Figure 8 As shown, the spout 26 includes a fixed shell 261, a movable shell 262, and a rotary drive 263. The fixed shell 261 is connected to the groove 244, and the movable shell 262 is disposed on the fixed shell 261. The movable shell 262 and the fixed shell 261 are slidably sealed together. The rotary drive 263 is disposed on the side of the fixed shell 261 (the rotary drive 263 is a servo motor). The working end of the rotary drive 263 is connected to the movable shell 262. A liquid outlet is provided at the end of the movable shell 262 away from the groove 244. During normal casting, the operator drives the motor... The control system 1 controls the tilting of the ladle 22 so that the molten alloy liquid is injected from the spout 26 into the casting mold on the mold conveying system 3. When it is necessary to adjust the casting angle or align the gate position of different specifications of casting molds, the control system will drive the movable shell 262 to rotate relative to the fixed shell 261 through the rotary drive component 263, so that the liquid outlet spout swings to the target angle on the preset trajectory, thereby accurately changing the outflow direction and landing position of the molten alloy liquid, thus ensuring that the alloy liquid is always accurately injected into the center of the mold pouring cup, avoiding problems such as metal splashing caused by gate offset.

[0027] like Figures 1-8 As shown, the casting device also includes a monitoring system (the monitoring system uses existing technologies such as industrial cameras and infrared thermal imagers). The monitoring system is set on the side of the mold conveying system 3 away from the ladle system 2. The monitoring system collects the quality of the casting mold in real time, as well as the splashing of molten metal and the filling status inside the casting mold during casting. This allows the control system to adjust the tilting speed and tilting angle of the drive mechanism 1, the descent depth of the separation module 25, the rotation angle of the nozzle 26, or the opening timing of the isolation component according to the type of abnormality.

[0028] Working principle: Before casting, the sealing plate 271 is flush with the inner bottom wall of the guide seat 24 under the drive of the third linear drive component 272. The electromagnet 278 is energized to attract and lock the positioning block 276. During casting, the drive mechanism 1 drives the ladle 22 to tilt, and the molten alloy flows into the guide seat 24, passing sequentially through the area below the second separation plate 255 and the first separation plate 254. The first separation plate 254 intercepts the surface slag, and the purified alloy liquid is injected into the casting mold cavity through the channel 243, the groove 244 and the nozzle 26. At the end of casting, the operator first opens the second linear drive component 253, and then starts the drive mechanism 1. After the drive unit 253 is activated, the drive lifting frame 252 moves down, so that the first separation plate 254 and the second separation plate 255 successively adhere to the inner bottom wall of the guide seat 24, forming a closed chamber between the first separation plate 254 and the second separation plate 255. The electromagnet 278 is de-energized, and the third linear drive unit 272 drives the sealing plate 271 to move down and open the slag discharge hole. The slag falls into the waste box 27 under gravity or the auxiliary blowing mechanism. After the slag is discharged, the sealing plate 271 is reset and relocked, and the separation module 25 moves up to the initial position. When the drive mechanism 1 is started, the ladle 22 returns to the initial position to facilitate the continued casting work of the subsequent casting mold.

[0029] Example 2: A casting apparatus for alloy materials, such as Figures 6-7 As shown, the specific structure is basically the same as that of Embodiment 1. The difference between this embodiment and Embodiment 1 is that the transmission assembly also includes a positioning block 276 and an electromagnet 278. The positioning block 276 is fixedly installed on the connecting rod 277. The electromagnet 278 is located inside the fixed sleeve 273 at one end near the sealing plate 271. A movable block 2761 is provided inside the positioning block 276 at one end near the electromagnet 278. The movable block 2761 at one end near the electromagnet 278 is magnetic. A positioning pin 2762 is provided inside the positioning block 276 at one end away from the electromagnet 278. The positioning pin 2762 is connected to the positioning block 276 through a slider, a groove and a return spring. A positioning hole is provided on the inner wall of the fixed sleeve 273. The positioning hole cooperates with the positioning pin 2762. The end of the movable block 2761 near the positioning pin 2762 has a wedge-shaped structure. The end of the positioning pin 2762 near the movable block 2761 has a wedge-shaped structure.

[0030] In Embodiment 1, the positioning block 276 is held in position solely by the magnetic attraction of the electromagnet 278. When the unexpected retraction force of the third linear drive 272 is large, the positioning block 276 can easily detach from the electromagnet 278, posing a safety hazard. In this embodiment, however, when the electromagnet 278 is energized, it generates a magnetic field that repels the movable block 2761. At this time, the movable block 2761 moves away from the electromagnet 278 (i.e., toward the positioning block 276). The wedge-shaped surface of the movable block 2761 slides relative to the wedge-shaped surface of the positioning pin 2762. Through the oblique driving action of the wedge-shaped surface, the axial movement of the movable block 2761 is converted into the radial outward movement of the positioning pin 2762. The movement of the moving block 2762 pushes the positioning pin 2762 to overcome the elastic force of the return spring and extend it out of the positioning block 276, and finally lock it into the positioning hole provided on the inner wall of the fixed sleeve 273, thereby realizing the mechanical locking between the connecting rod 277 and the fixed sleeve 273. When unlocking is required, the electromagnet 278 is de-energized or energized in the reverse direction. Under the elastic force of the return spring, the positioning pin 2762 retracts from the positioning hole into the positioning block 276, and the moving block 2761 retracts towards the electromagnet 278. Through the above technical solution, this embodiment significantly improves the self-locking capability and reliability of the transmission component, and effectively avoids the risk of the slag discharge through hole opening due to the accidental retraction of the third linear drive component 272 during the casting process.
