Description

Technical Field

[0001] This invention belongs to the field of aluminum ingot casting technology, and specifically relates to a cleaning device for an aluminum ingot casting conveyor. Background Technology

[0002] Aluminum ingot casting conveyors are key equipment in the aluminum processing industry for forming molten aluminum. The cleanliness of the molds directly affects the surface finish of the aluminum ingots and the continuity of production. During the aluminum ingot casting process, impurities such as aluminum slag, oxides, and release agents easily remain on the inner wall of the mold. Insufficient cleaning not only leads to difficulties in demolding the aluminum ingots and causes surface defects, but also accelerates mold corrosion and increases downtime maintenance costs. Therefore, an efficient mold cleaning process is one of the core links in ensuring the quality of aluminum ingots and the efficiency of the production line.

[0003] Currently, the cleaning device for aluminum ingot casting conveyors includes a water washing section and an air washing section. The water washing section uses a water pump to pressurize cleaning water, which is then sprayed directionally into the mold cavity through nozzles in the outlet pipe. The impact force of the water flow washes away residual impurities, which fall onto a filter screen for easy recycling. The air washing section uses a fan to generate a high-speed airflow to blow clean the mold surface. This removes fine particles that are difficult for water to reach and accelerates the evaporation of moisture from the mold surface, shortening the drying time.

[0004] However, both water washing and air washing are non-contact cleaning methods. In actual use, non-contact cleaning is not effective at removing impurities. The bottom and corners of the mold often have sticky blocky residues formed due to the condensation of molten aluminum. Water flow alone cannot effectively remove these residues, leading to repeated accumulation of impurities and even the formation of hardened layers that are difficult to remove. Summary of the Invention

[0005] This invention addresses the problem that existing cleaning devices often suffer from insufficient cleaning power, leading to the accumulation of impurities and the formation of a hardened layer. It provides a cleaning device for an aluminum ingot casting conveyor that has sufficient cleaning power and is less prone to impurity residue and hardening.

[0006] To solve the above problems, the technical solution adopted by the present invention is a cleaning device for an aluminum ingot casting conveyor, including a base plate located below the aluminum ingot casting conveyor. A support frame is fixed on the base plate and fixedly connected to the aluminum ingot casting conveyor. At least one set of cleaning mechanisms is provided on the base plate, each set of cleaning mechanisms including a cleaning block that can rotate and clean the inner cavity of the mold of the aluminum ingot casting conveyor. A rinsing mechanism is provided on the base plate, which can spray rinsing water into the inner cavity of the mold of the aluminum ingot casting conveyor. A driving mechanism is also provided on the base plate, which can control the lifting and lowering of the cleaning mechanism and control the spraying direction of the rinsing mechanism.

[0007] In this technical solution, at least one set of cleaning mechanisms is installed on the base plate. Each set of cleaning mechanisms includes a cleaning block that can rotate and clean the inner cavity of the mold in the aluminum ingot casting conveyor. Multiple sets of cleaning mechanisms remove impurities by repeatedly cleaning the inner cavity of the mold. The rinsing mechanism sprays rinsing water into the inner cavity of the mold, which can simultaneously rinse away the cleaned impurities and soften and solidify them, facilitating the cleaning of the cleaning blocks. The drive mechanism controls the raising and lowering of the cleaning mechanisms, so that multiple sets of cleaning blocks rise synchronously into the inner cavity of the mold to perform the cleaning action, or descend synchronously so that the conveyor can remove the cleaned mold; on the other hand, it adjusts the spray direction of the rinsing mechanism to ensure that the rinsing water fully covers all cleaning blocks. Therefore, this device achieves impurity removal through the coordinated operation of rinsing water softening impurities and multiple sets of cleaning blocks repeatedly cleaning, using a composite method that combines non-contact and contact cleaning, effectively preventing the accumulation of impurities and the formation of a hardened layer.

[0008] Furthermore, the cleaning mechanism consists of two sets, arranged front and back along the mold movement direction of the aluminum ingot casting conveyor. A rinsing mechanism is positioned between the two sets, and the rinsing water sprayed by the rinsing mechanism can reach above both sets of cleaning mechanisms. The front cleaning mechanism performs an initial rotating cleaning of the mold cavity, removing loose impurities such as scum and debris through contact cleaning, breaking the initial adhesion between impurities and the mold cavity. The rinsing mechanism in the middle sprays rinsing water above both the front and rear cleaning mechanisms. This serves two purposes: firstly, it washes away impurities removed during the front cleaning process, preventing secondary adhesion or accumulation; secondly, it softens any remaining solidified impurities in the mold cavity, reducing their hardness and adhesion, thus creating conditions for the rear cleaning mechanism to clean. The rear cleaning mechanism performs a secondary cleaning of the softened residual impurities after rinsing. At this time, the impurities are more easily peeled off by the cleaning blocks due to their softening, which can effectively remove solidified impurities that are difficult to handle in the initial cleaning, achieving a layered cleaning effect of "initial cleaning of loose impurities - softening of solidified impurities - removal of solidified impurities".

[0009] Furthermore, the cleaning block is made of elastic material. The length of the cleaning block is the same as the length of the mold cavity of the aluminum ingot casting conveyor, and the outer contour of the cleaning block fits the contour of the mold cavity. A scraper is fixed at the top center of the cleaning block, with its length direction matching that of the cleaning block. First, the use of elastic material allows the cleaning block to tightly conform to the complex curved surfaces of the mold cavity, such as its uneven structure, corners, and gaps, during rotational cleaning, avoiding blind spots caused by rigid contact. Simultaneously, the elastic material buffers the mechanical impact between the cleaning block and the mold cavity, reducing wear on the mold cavity during cleaning. Second, the outer contour of the cleaning block fits the contour of the mold cavity, ensuring complete contact between the surface of the cleaning block and the mold cavity during rotation, eliminating the "edge-skimming" problem of traditional flat cleaning components. Finally, the scraper fixed at the top center of the cleaning block can linearly scrape areas in the mold cavity where impurities easily accumulate during rotation, specifically breaking down the hardened layer of aluminum slag.

[0010] Furthermore, each cleaning mechanism also includes a cylinder located below the cleaning block. The cylinder's axis is the same as the length of the cleaning block. The upper half of the cylinder is fixedly connected to the bottom of the cleaning block. A rack is fixed to the cylindrical surface of the lower half of the cylinder, and a gear is positioned below the rack. The gear meshes with the rack, and a component frame is positioned below the gear. The length of the component frame is the same as the length of the cleaning block, and both its length and width are smaller than the cleaning block. A stepper motor is fixed inside the component frame, and the output shaft of the stepper motor is fixedly connected to the gear. The stepper motor can precisely control the rotation angle and speed through pulse signals, achieving small-angle high-frequency oscillation of the cleaning block. This motion mode enhances the scraping effect on the corner areas of the mold cavity. In addition, the stepper motor, gears, and other precision components are enclosed within the component frame to prevent contaminants such as aluminum slag and coolant from entering, thus extending their service life. The component frame is smaller than the cleaning block to prevent impurities from falling directly into the component frame during cleaning.

[0011] Furthermore, a waste frame is fixed at the bottom of the component frame. The length direction of the waste frame is the same as that of the component frame, and the length and width of the waste frame are both greater than those of the cleaning block. Two connecting rods are fixed on the inner bottom surface of the waste frame. The two connecting rods are vertically arranged at both ends of the cylinder, and the upper ends of the two connecting rods are rotatably connected to both ends of the cylinder, respectively.

[0012] The length and width of the waste box are both greater than the cleaning block, forming an extended enclosing structure that completely covers the movement range of the cleaning block. When the cleaning block swings and sweeps, the detached aluminum slag, oxide scale, and other impurities fall directly into the waste box, rather than scattering on the component frame or drive mechanism. This avoids the accumulation of impurities and contamination of precision components such as gears and stepper motors, effectively reducing the risk of equipment failure. In addition, the connecting rods are vertically arranged at both ends of the cylinder, and their height matches the depth of the waste box, ensuring that the cylinder and connecting rods do not collide with the mold cavity or other components of the aluminum ingot casting conveyor during the lifting and lowering process.

[0013] Furthermore, the inner side of the support frame is provided with a vertically arranged sliding groove. Both ends of the waste box are fixed with vertically arranged sliders that are slidably connected to their corresponding sliding grooves. The vertical arrangement of the sliding grooves strictly limits the movement direction of the sliders, ensuring that the waste box can only move vertically. This prevents lateral displacement of the cleaning block when it is inserted into or withdrawn from the mold cavity, ensuring precise alignment between the cleaning block and the mold cavity.

[0014] Furthermore, the rinsing mechanism includes a positioning frame, the bottom of which is fixedly connected to the upper surface of the base plate. A water pipe is positioned above the positioning frame, with its axial direction aligned with the length of the cleaning block. Several nozzles are evenly distributed along the water pipe's axis, with their spray direction pointing upwards. Both ends of the water pipe are rotatably connected to two fixed plates, which are fixedly connected to the top of the positioning frame. The alignment of the water pipe's axial direction with the length of the cleaning block ensures that the nozzle coverage area perfectly matches the cleaning area of ​​the block, guaranteeing precise application of the rinsing water flow to the areas within the mold cavity to be cleaned. The evenly distributed nozzles along the water pipe's axis generate a dense rinsing water flow, covering the entire length of the mold cavity and eliminating rinsing blind spots.

[0015] Furthermore, the drive mechanism includes a cylinder, the cylinder barrel of which is fixedly connected to the upper surface of the base plate. The piston rod of the cylinder extends and retracts perpendicular to the length direction of the cleaning block. The cylinder is equipped with a lifting component and a swinging component. The lifting component is located below the waste box and controls its lifting and lowering; the swinging component is located below the water pipe and controls its swinging motion. By using a single cylinder, the lifting and lowering of the waste box and the swinging of the water pipe start and end simultaneously. This design completely avoids the unavoidable motion delay problem in traditional multi-power source drives. In previous schemes that used multiple motors or drive devices to control different mechanisms separately, the differences in the start-up response time and speed adjustment accuracy of each motor often resulted in delays in the coordination of actions between different mechanisms. This slight time difference leads to significant efficiency losses and cleaning blind spots in the cleaning process. A single cylinder unifies the power source for the lifting and lowering of the waste box and the swinging of the water pipe. When the cylinder piston rod begins to extend and retract, it can simultaneously drive the lifting and swinging components.

[0016] Furthermore, the lifting assembly includes a movable frame, which is fixedly connected to the piston rod of the cylinder. The bottom of the movable frame is slidably connected to the upper surface of the base plate. Inclined grooves are provided on both sides of the movable frame near the support frame. These grooves are inclined, and protrusions that can slide along them are installed within them. The ends of the protrusions near the support frame are fixedly connected to the lower ends of the lifting columns, and the upper ends of the lifting columns are fixedly connected to the bottom of the waste box. Through the sliding cooperation of the inclined grooves and protrusions, the horizontal thrust of the cylinder is converted into the vertical lifting motion of the waste box. The symmetrically arranged inclined grooves and protrusions on both sides of the movable frame form a double-guide structure, effectively constraining the movement trajectory of the waste box, preventing lateral swaying or tilting during lifting, and ensuring accurate insertion of the cleaning block into the mold cavity.

[0017] Furthermore, the positioning frame has horizontally arranged straight grooves on both sides near the support frame. The swing assembly includes two swing rods located outside the two fixed plates. The upper ends of the two swing rods are fixedly connected to both ends of the water pipe. The lower ends of the two swing rods have movable grooves, the length of which is the same as that of the swing rods. An extension column is installed in the movable groove, one end of which is slidably connected to the movable groove, and the other end of which passes through the straight groove and is fixedly connected to the piston rod of the cylinder. When the piston rod of the cylinder extends or retracts, the extension column slides along the horizontal straight groove. Through the cooperation of the movable groove and the swing rod, the movement of the extension column is directly converted into the rotation of the swing rod, thereby driving the water pipe to rotate and changing the spray direction.

[0018] As can be seen from the above technical solution, the advantages of this invention are as follows: In this technical solution, the front cleaning mechanism first performs an initial rotating cleaning of the inner cavity of the aluminum ingot casting conveyor mold, removing loose impurities through contact cleaning. The rinsing mechanism in the middle position can swing, spraying rinsing water above the front and rear cleaning mechanisms. On the one hand, it rinses the impurities removed by the front cleaning mechanism, preventing secondary adhesion or accumulation; on the other hand, it softens the solidified impurities remaining in the mold cavity, reducing the hardness and adhesion of the impurities, creating conditions for the rear cleaning mechanism to clean. The rear cleaning mechanism performs a secondary cleaning of the softened residual impurities. At this time, the impurities are more easily peeled off by the cleaning blocks due to softening, effectively removing solidified impurities that are difficult to handle in the initial cleaning, achieving a layered cleaning effect of "initial cleaning of loose impurities - softening of solidified impurities - removal of solidified impurities". In summary, this device achieves impurity removal through the coordinated operation of rinsing water softening impurities and repeated cleaning by multiple sets of cleaning blocks, using a composite method combining non-contact and contact cleaning, effectively preventing the accumulation of impurities to form a hardened layer.

Detailed Implementation

[0022] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] A cleaning device for an aluminum ingot casting conveyor 1, such as Figure 1As shown, the system includes a base plate 3, which is located below the aluminum ingot casting conveyor 1. Two support frames 2 are welded to the base plate 3, symmetrically distributed along the longitudinal center plane of the base plate 3, and fixedly connected to both sides of the aluminum ingot casting conveyor 1. At least one set of cleaning mechanisms 6 is provided on the base plate 3, capable of cleaning the inner cavity of the mold at the bottom of the aluminum ingot casting conveyor 1. A rinsing mechanism 7 is provided on the base plate 3, capable of spraying rinsing water into the inner cavity of the mold at the bottom of the aluminum ingot casting conveyor 1. A drive mechanism is also provided on the base plate 3, capable of controlling the lifting and lowering of the cleaning mechanism 6 and controlling the spraying direction of the rinsing mechanism 7.

[0024] like Figure 2-3 As shown, in this specific embodiment, there are two sets of cleaning mechanisms 6, which are distributed in a front-to-back manner along the mold movement direction of the aluminum ingot casting conveyor 1. The rinsing mechanism 7 is located between the two sets of cleaning mechanisms 6, and the rinsing water jet sprayed by the rinsing mechanism 7 can be sprayed above the two sets of cleaning mechanisms 6.

[0025] like Figure 4 As shown, each cleaning mechanism 6 includes a cleaning block 18, which can rotate and clean the inner cavity of the mold in the aluminum ingot casting conveyor 1. The cleaning block 18 is made of elastic material and is elongated in shape. Its length direction is the same as the length direction of the inner cavity of the mold in the aluminum ingot casting conveyor 1, and the outer contour of the cleaning block 18 fits the contour of the inner cavity of the mold in the aluminum ingot casting conveyor 1, allowing it to be completely inserted into the inner cavity of the mold in the aluminum ingot casting conveyor 1. It fits tightly with the contour of the inner cavity of the mold through its own elastic deformation. A scraper 28 is fixed at the top center of the cleaning block 18. The scraper 28 is made of hard plastic material, and its length direction is the same as the length direction of the cleaning block 18, and the length of the scraper 28 is the same as the length of the cleaning block 18. When the cleaning block 18 is inserted into the inner cavity of the mold in the aluminum ingot casting conveyor 1, the top of the scraper 28 will fit tightly with the bottom surface of the inner cavity of the mold in the aluminum ingot casting conveyor 1.

[0026] In this embodiment, the cleaning block 18 is made of rubber. This material allows the cleaning block 18 to elastically deform and tightly conform to the complex curved surfaces such as the concave and convex structures, corners, and gaps inside the mold cavity of the aluminum ingot casting conveyor 1 during rotational cleaning, avoiding cleaning blind spots caused by rigid contact. Simultaneously, the rubber material has a certain degree of wear resistance, enabling it to remove impurities without abrading the inner cavity of the aluminum ingot casting conveyor 1 mold, and it also has a certain service life. The scraper blade 28 adopts a structure with an internal metal sheet to improve strength. The metal sheet is wrapped with hard plastic, which improves the strength of the scraper blade 28 while preventing damage to the inner cavity of the aluminum ingot casting conveyor 1 mold.

[0027] Each cleaning mechanism 6 also includes a cylinder 17, which is horizontally arranged below the cleaning block 18, with its axis aligned with the length of the cleaning block 18. A semi-circular groove is provided at the bottom of the cleaning block 18. The upper half of the cylinder 17 is engaged and fixed within this groove. A rack 19, semi-circular in shape, is welded to the cylindrical surface of the lower half of the cylinder 17. A gear 16 is positioned below the rack 19, with its axis aligned with the length of the cleaning block 18 and meshing with the rack 19. A component frame 14 is positioned below the gear 16, with its length aligned with the length of the cleaning block 18, and both its length and width being smaller than that of the cleaning block 18. The component frame 14 is a sealed frame with a rectangular slot inside. The gear 16 is located in the rectangular slot of the component frame 14. A stepper motor 15 is also installed in the rectangular slot. The stepper motor 15 is fixed to the bottom of the rectangular slot of the component frame 14 by bolts. The axial direction of its output shaft is the same as the length direction of the cleaning block 18. The output shaft of the stepper motor 15 is fixedly connected to the center of the end face of the gear 16 by bolts.

[0028] A scrap frame 12 is provided below the component frame 14. The length direction of the scrap frame 12 is the same as that of the component frame 14, and the length and width of the scrap frame 12 are both greater than those of the cleaning block 18. The scrap frame 12 is a frame with a rectangular slot inside. The bottom of the component frame 14 is welded to the bottom surface of the rectangular slot of the scrap frame 12. Two connecting rods 13 are provided in the rectangular slot of the scrap frame 12. The two connecting rods 13 are distributed at both ends of the cylinder 17, and are both arranged vertically. Their upper ends are rotatably connected to both ends of the cylinder 17, and their lower ends are welded to the bottom of the rectangular slot of the scrap frame 12.

[0029] The waste frame 12 has vertically arranged elongated sliders 30 welded to both ends near the edge of the base plate 3. Vertically arranged grooves 29 are provided on the inner sides of both support frames 2, with the positions of the grooves 29 corresponding to the sliders 30. The sliders 30 are engaged within the corresponding grooves 29 and can drive the waste frame 12 to slide vertically within the grooves 29.

[0030] In this specific embodiment, the rinsing mechanism 7 includes a positioning frame 20, which is located between the two cleaning mechanisms 6 and includes a horizontal plate and a vertical plate. The horizontal plate is a horizontally arranged elongated strip, and its length direction is the same as the length direction of the cleaning block 18. The vertical plate is located below the horizontal plate, is vertically arranged, and there are two of them. The two vertical plates are parallel to each other, and their tops are welded to the two sides of the horizontal plate near the edge of the bottom plate 3, respectively, and their bottoms are welded to the upper surface of the bottom plate 3.

[0031] like Figure 5As shown, a water pipe 26 is positioned above the positioning frame 20. The axial direction of the water pipe 26 is the same as the length direction of the cleaning block 18. Several nozzles 27 are arranged on its outer wall, evenly distributed along the axis of the water pipe 26, with the spray direction pointing upwards. Both ends of the water pipe 26 pass through two fixing plates 23 and are rotatably connected to the fixing plates 23. The bottoms of the two fixing plates 23 are welded to the tops of two upright plates, respectively. One end of the water pipe 26 is connected to one end of a rubber tube, and the other end of the rubber tube is connected to a water pump, which is connected to an external water tank.

[0032] In this specific embodiment, the drive mechanism includes a lifting assembly and a swing assembly. There are two sets of lifting assemblies, which are respectively arranged below the two waste boxes 12 of the two sets of cleaning mechanisms 6, and can control the lifting and lowering of the waste boxes 12. The swing assembly is located below the water pipe 26 and can control the swinging of the water pipe 26.

[0033] The lifting assembly includes a movable frame 8, the bottom of which slides against the upper surface of the base plate 3. Inclined grooves 9 are provided on both sides of the movable frame 8 near the support frame 2. Each of the two inclined grooves 9 contains a protruding post 11 that can slide along the corresponding inclined groove 9. Two vertically arranged lifting columns 10 are provided outside the movable frame 8. The two lifting columns 10 are located outside the two protruding posts 11, with their lower ends fixedly connected to the ends of the corresponding protruding posts 11 near the support frame 2, and their upper ends welded to the bottom of the waste frame 12.

[0034] The positioning frame 20 has horizontally arranged straight grooves 21 on both sides near the support frame 2. The swing assembly includes two swing rods 24, which are located on the outside of the two fixed plates 23, and their upper ends are fixedly connected to both ends of the water pipe 26. The lower ends of the two swing rods 24 are provided with U-shaped movable grooves 25. The length direction of the movable grooves 25 is the same as that of the swing rods 24. An extension column 22 is provided in the movable groove 25. One end of the extension column 22 is engaged in the movable groove 25 and can slide along the movable groove 25, and the other end passes through the straight groove 21 and can slide along the straight groove 21.

[0035] The drive mechanism also includes a cylinder 4, with the lifting assembly and swing assembly mounted on the cylinder 4. The cylinder 4 is horizontally arranged, its cylinder barrel fixedly connected to the upper surface of the base plate 3 by bolts. The extension and retraction direction of the piston rod is perpendicular to the length direction of the cleaning block 18. The end of the piston rod of the cylinder 4 is fixedly connected to one end of the smooth rod 5, and the axis of the smooth rod 5 coincides with the axis of the piston rod of the cylinder 4. The other end of the smooth rod 5 passes through two moving frames 8 sequentially and is fixedly connected to the two moving frames 8 by bolts. Furthermore, the cylindrical surface of the smooth rod 5 is welded to two extension columns 22 below the positioning frame 20.

[0036] The specific usage process of this invention is as follows: the water tank is connected to the water pipe 26 through a rubber tube to provide a water source for the entire showering operation, ensuring that the showering operation can proceed smoothly. At this time, the entire device is in standby mode, and all components are in their initial positions. Specifically, the waste box 12 is located in the initially set position, the cleaning block 18 has not yet been inserted into the mold cavity of the aluminum ingot casting conveyor 1, and the water pipe 26 is also maintained at the initial angle.

[0037] When cleaning is required, cylinder 4 is activated, and its piston rod extends. This extension pushes the connected guide rod 5 forward. Since the guide rod 5 is fixedly connected to the two moving frames 8, the two moving frames 8 move synchronously with the guide rod 5. Below the waste container 12, the protrusion 11 at the bottom of the lifting column 10 is slidably mounted within the inclined groove 9 on the side of the moving frame 8. As the moving frame 8 moves with the guide rod 5, the protrusion 11 slides along the direction of the groove within the inclined groove 9. Due to the specific inclined structure of the inclined groove 9, this sliding causes the protrusion 11 to push the lifting column 10 upward. As the lifting column 10 rises, the connected waste container 12 also rises accordingly.

[0038] During the upward movement of the waste frame 12, the slider 30 on the waste frame 12 slides along the pre-set groove 29 on the support frame 2. This cooperative structure of the slider 30 and the groove 29 ensures that the waste frame 12 maintains a vertical lifting motion during the upward movement without deviation or shaking, thereby ensuring that the cleaning block 18 can be accurately inserted into the mold cavity of the aluminum ingot casting conveyor 1.

[0039] Once the waste box 12 rises to the predetermined position, the stepper motor 15 inside the component box 14 starts. The output of the stepper motor 15 drives the gear 16 connected to it to rotate in a step-by-step reciprocating manner. Because the gear 16 and the rack 19 in the lower half of the cylinder 17 are meshed with each other, when the gear 16 rotates, it will drive the cylinder 17 to oscillate back and forth.

[0040] Since the upper part of the cylinder 17 is fixedly connected to the cleaning block 18, the cleaning block 18 will swing along with the cylinder 17. During the swinging process of the cleaning block 18, the scraper 28 on its top will contact the bottom surface of the mold and scrape away the impurities and waste on the bottom surface of the mold. Through the omnidirectional swinging of the cleaning block 18, the inner cavity of the mold of the aluminum ingot casting conveyor 1 can be thoroughly cleaned, effectively removing various impurities and waste adhering to the inner cavity of the mold.

[0041] Meanwhile, since the extension column 22 is fixedly connected to the guide rod 5, the movement of the guide rod 5 will cause the extension column 22 to move synchronously. The extension column 22 moves within the linear grooves 21 on both sides of the positioning frame 20, and the end of the extension column 22 is movably engaged in the movable groove 25 at the bottom of the swing rod 24. In this way, the linear motion of the extension column 22 is converted into the rotational motion of the swing rod 24 through this special connection structure.

[0042] Since the swing rod 24 is fixedly connected to the water pipe 26, the rotation of the swing rod 24 will cause the water pipe 26 to swing. As the water pipe 26 swings, several nozzles 27 arranged at the top of the water pipe 26 begin to spray water. The simultaneous spraying of water from these nozzles 27 can form a large-area rinsing coverage area. The powerful water flow generated by the simultaneous spraying of water from multiple nozzles 27 can wash away dust, debris and other impurities attached to the mold cavity, thereby achieving the purpose of rinsing the mold cavity from different angles.

[0043] After the cleaning and rinsing operations are completed, the piston rod of cylinder 4 begins to retract. The retraction of the piston rod causes the guide rod 5 to move in the opposite direction. Since the moving frame 8 is fixedly connected to the guide rod 5, the moving frame 8 will also move in the opposite direction.

[0044] During the reverse movement of the moving frame 8, the protrusion 11 at the bottom of the lifting column 10 below the waste frame 12 will slide in the reverse direction within the inclined groove 9. This reverse sliding will cause the lifting column 10 to descend, thereby causing the waste frame 12 to descend. As the waste frame 12 descends, the cleaning block 18 will exit from inside the mold and eventually return to its initial position.

[0045] At this point, the aluminum ingot casting conveyor 1 begins operation, moving the molds on it forward. The molds, cleaned by the first set of cleaning mechanisms 6, are sequentially transferred to the top of the second set of cleaning mechanisms 6, where they undergo a second cleaning. This method ensures a more thorough cleaning of the molds, guaranteeing the quality of the aluminum ingot casting.

[0046] As can be seen from the above embodiments, the beneficial effects of the present invention are as follows: In this specific embodiment, the front cleaning mechanism first performs an initial rotating cleaning of the inner cavity of the aluminum ingot casting conveyor mold, removing loose impurities through contact cleaning. The rinsing mechanism in the middle position can swing, spraying rinsing water flow above the front and rear cleaning mechanisms. On the one hand, it rinses the impurities removed by the front cleaning mechanism, preventing secondary adhesion or accumulation; on the other hand, it softens the solidified impurities remaining in the mold cavity, reducing the hardness and adhesion of the impurities, creating conditions for the rear cleaning mechanism to clean. The rear cleaning mechanism performs a secondary cleaning of the softened residual impurities. At this time, the impurities are more easily peeled off by the cleaning blocks due to softening, effectively removing solidified impurities that are difficult to handle in the initial cleaning, achieving a layered cleaning effect of "initial cleaning of loose impurities - softening of solidified impurities - removal of solidified impurities". In summary, this device achieves impurity removal through the coordinated operation of rinsing water softening impurities and repeated cleaning by multiple sets of cleaning blocks, using a composite method combining non-contact and contact cleaning, effectively preventing the accumulation of impurities to form a hardened layer.
