Description

Technical Field

[0001] This invention relates to the field of non-ferrous metal die casting technology, and in particular to a highly adaptable non-ferrous metal die casting equipment and method. Background Technology

[0002] Die casting, also known as pressure casting, is a molding process in which molten non-ferrous metal alloy is injected into a precision mold cavity under high speed and pressure, and then cooled and solidified to form the desired casting. Pressure casting is an indispensable key technology in the automotive, aerospace, electronics and communications, and daily hardware industries. Pressure casting has high productivity, is easy to mechanize and automate, and can produce thin-walled castings with complex shapes. Traditional die casting equipment usually consists of several core parts, including an injection system, a mold clamping system, a hydraulic system, a control system, and molds. Its basic working principle is as follows: First, the mold clamping mechanism locks two molds with cavities to form a closed space. Then, the injection punch, driven by the hydraulic cylinder, pushes the molten metal from the pressure chamber into the mold cavity at extremely high speed. The molten metal fills the cavity and solidifies under great pressure. Finally, the mold is opened, and the ejector mechanism pushes out the formed casting. During pressure casting, a release agent needs to be sprayed into the cavity to facilitate the final removal of the casting.

[0003] An investigation revealed that a Chinese invention patent discloses a die-casting apparatus for non-ferrous metal production (publication number: CN120961883 A), which includes a die-casting machine base. The side of the die-casting machine base is provided with an injection mechanism. A mold-closing mechanism is fixedly connected to the top of the die-casting machine base away from the injection mechanism. A die-casting moving mold is movably connected to the side of the mold-closing mechanism close to the injection mechanism. A die-casting fixed mold is provided on the side of the die-casting moving mold away from the mold-closing mechanism.

[0004] Although the aforementioned patent achieves good spraying effect by adapting the nozzle to the cavities of the die-casting moving mold and die-casting stationary mold, ensuring the effective spraying of the release agent, the non-ferrous metal die-casting workshop environment contains a large amount of suspended particles such as metal dust, flash debris, and mold lubricant residue. If the nozzle is stored exposed, these dust particles can easily accumulate around the nozzle or even enter the channel, causing nozzle blockage. Nozzle blockage directly damages the uniformity and coverage of the release agent spraying, leading to problems such as difficulty in demolding and surface defects in the casting. At the same time, inadequate mold cavity cleaning can result in residual metal flash, old release agent carbon deposits, oil stains, and small impurities in the mold cavity affecting the uniformity of the release agent spraying, further impacting the quality of metal die casting.

[0005] Therefore, this application provides a highly adaptable non-ferrous metal die-casting equipment and method to meet the requirements. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a highly adaptable non-ferrous metal die-casting equipment and method to solve the problem of uneven spraying of release agent caused by mold cavity residue and nozzle blockage.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A highly adaptable non-ferrous metal die-casting equipment includes a die-casting equipment body, a support, and a mounting base. The support is fixedly connected to the die-casting equipment body. A hydraulic rod is fixedly connected between the mounting base and the support. A housing assembly is symmetrically arranged on both sides of the mounting base. Multiple spraying rods are arranged in an array on the housing assembly. A cleaning mechanism is provided on the outer side of each spraying rod. The cleaning mechanism is used to clean and remove impurities from the mold cavity. The cleaning mechanism includes a mounting cylinder, a connecting cylinder, and multiple brush plates. A limiting ring is fixedly connected to the outer wall of each spraying rod. Multiple limiting mechanisms are provided between the connecting cylinder and the limiting ring. The limiting mechanisms are used to fix and limit the distance between the connecting cylinder and the spraying rod. Each limiting mechanism includes a connecting rod, a limiting block, and a third spring.

[0008] Optionally, the housing assembly includes a mounting shell, a connecting shell, and a mounting plate. The connecting shell is fixedly connected between the mounting shell and the mounting plate. The mounting cylinder passes through the mounting plate and is rotatably connected to the mounting plate. A connecting pipe is connected between the spraying rods. A connecting port is fixedly connected to the outer wall of the connecting shell, and the connecting port is connected and communicates with the connecting pipe.

[0009] Optionally, the connecting cylinder is slidably connected to the mounting cylinder, and the multiple brush plates are arranged in a circle and rotatably connected to the end of the connecting cylinder by a torsion spring. The mounting plate is rotatably connected to a driving wheel, multiple driven wheels and idler wheels. The driven wheels are coaxially fixed to the mounting cylinder, and the driving wheel and idler wheels are both meshed between the multiple driven wheels.

[0010] Optionally, a second motor is fixedly connected to the side of the mounting housing near the mounting plate, and the output end of the second motor is fixed coaxially with the drive wheel.

[0011] Optionally, a slide rod and a rack are fixedly connected to the side of the mounting shell away from the mounting plate, and both the slide rod and the rack slide through the mounting base. A gear is rotatably connected inside the mounting base, and the gear meshes with the rack. A first motor is fixedly connected to the outer wall of the mounting base, and the output end of the first motor is coaxially fixed with the gear.

[0012] Optionally, the outer wall of the connecting cylinder is provided with multiple mounting grooves, and the limiting mechanism is set in the mounting groove. The outer wall of the mounting groove is provided with a through hole, and the limiting block is slidably connected in the through hole. The end of the limiting block is inserted into the limiting ring. The side wall of the limiting block is symmetrically fixed with protrusions, and an elastic sheet is fixedly connected between the protrusion and the inner wall of the mounting groove.

[0013] Optionally, the connecting rod is slidably connected in the mounting groove and passes through the limiting block. A slider is fixedly connected to the top of the connecting rod, and an iron plate is fixedly connected to the bottom of the connecting rod. Both the slider and the iron plate are slidably connected in the mounting groove. Fixing blocks are fixedly connected to both the connecting rod and the inner wall of the mounting groove, and a third spring is fixedly connected between the two fixing blocks. A stop block is fixedly connected in the mounting groove and is positioned between the slider and the limiting block.

[0014] Optionally, an annular groove is provided on the outer wall of the mounting cylinder, and a plurality of electromagnets, a guide rod and a second spring are fixedly connected in the annular groove. The electromagnets are positioned corresponding to the iron sheet. The second spring is sleeved on the guide rod and the end of the second spring is fixedly connected to the connecting cylinder. The end of the guide rod is slidably inserted into the side wall of the connecting cylinder.

[0015] Optionally, the mounting housing has multiple sliding grooves. The end of the spraying rod is sequentially fixedly connected to a circular plate, a circular rod, and a positioning rod, and the positioning rod is slidably connected in the sliding groove. A first spring is sleeved on the circular rod, and the two ends of the first spring are fixedly connected to the circular plate and the inner wall of the sliding groove, respectively. A limit frame is slidably connected inside the mounting housing. Multiple top blocks are fixedly connected to the limit frame, and the top blocks correspond to the positions of the positioning rod. A cylinder is fixedly connected to the outer wall of the mounting housing, and the output shaft of the cylinder is fixedly connected to the limit frame.

[0016] This application also provides another technical solution: a highly adaptable non-ferrous metal die-casting method, the specific steps of which are as follows: S1: Start the first motor to drive the gear to rotate. Under the action of the gear, drive the two meshing racks to rotate in opposite directions, thereby driving the outer shell assembly and the cleaning mechanism to move into the mold cavity; S2: The moving brush plate and connecting cylinder abut against the mold cavity. Driven by the reaction force, the connecting cylinder drives the spraying rod to move through the limiting block and the limiting ring. The spraying rod drives the positioning rod to move through the round rod. At the same time, the round plate compresses the first spring. According to the synchronous shape of the inner wall of the mold cavity, the compression degree of the first spring is different, always keeping the brush plate in contact with the inner wall of the mold cavity. At this time, the cylinder is activated to push the limiting frame to move. The top block on the limiting frame squeezes and limits the positioning rod. S3: Start the second motor to drive the drive wheel to rotate. The drive wheel drives multiple meshed driven wheels to rotate. The rotating driven wheels drive the remaining driven wheels to rotate through the idler wheel. This drives the mounting cylinder, which is fixed coaxially with the driven wheels, to rotate. The mounting cylinder drives the brush plate to rotate on the inner wall of the mold cavity through the connecting cylinder to clean the mold cavity. S4: When the electromagnet is energized, the electromagnet attracts the iron sheet and sticks to it. The iron sheet drives the connecting rod to move and stretches the third spring. During the movement of the connecting rod, it will push the limiting block to move, causing the limiting ring of the limiting block to separate and release the limitation on the spraying rod. At this time, the moving connecting rod drives the slider to abut against the stop block. The continuing to move connecting rod will drive the connecting cylinder to move, causing it to compress the second spring. S5: During the downward movement of the connecting cylinder, the brush plate gradually approaches the spray bar. The top of the spray bar will push the moving brush plate open, and then the release agent will be sprayed from the nozzle at the end of the spray bar onto the inner wall of the mold cavity.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, a cleaning mechanism is installed to pre-clean the inner wall of the mold cavity before spraying the release agent. When the brush plate enters the mold cavity with the connecting cylinder, under the reaction force, the first spring adaptively adjusts the degree of compression according to the shape of the inner wall of the mold cavity, ensuring that the brush plate always fits tightly against the inner wall of the mold cavity. Subsequently, the second motor drives the driving wheel, driven wheel, and idler wheel to rotate, causing the mounting cylinder and connecting cylinder to rotate, so that the brush plate rotates and rubs at high speed against the inner wall of the mold cavity. This effectively removes residual metal flash, old release agent carbon deposits, oil stains, and small impurities, preventing these residues from affecting the uniform spraying of the release agent and laying the foundation for high-quality spraying.

[0018] Through the integrated design of the cleaning mechanism and the spraying rod, after cleaning, the iron plate is attracted by an electromagnet, and the linkage connecting rod releases the limiting block from the spraying rod, causing the connecting cylinder to move down. This allows the brush plate to be pushed open by the top of the spraying rod, exposing the nozzle for mold release agent spraying. At this time, the brush plate is away from the nozzle and will not obstruct the spraying. In the non-working state, the brush plate is reset under the action of the torsion spring, wrapping around the nozzle of the spraying rod to form a physical barrier. This effectively prevents impurities such as metal dust and flash debris from accumulating around the nozzle or entering the channel, avoiding nozzle clogging, ensuring the uniformity and coverage of the mold release agent spraying, thereby improving the quality of metal die casting and solving the problem of uneven mold release agent spraying caused by mold cavity residue and nozzle clogging.

[0019] By setting a limiting mechanism, the distance between the brush plate and the nozzle at the end of the spray bar can be kept fixed. Under the action of the first spring, the brush plate can be closely attached to the irregular inner wall of the mold cavity. At this time, the distance between multiple nozzles and different positions of the inner wall of the mold cavity can be kept consistent, thereby ensuring the uniformity of the release agent spraying amount and avoiding excessive or insufficient local spraying due to distance differences, further improving the uniformity of spraying.

[0022] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0023] like Figures 1 to 10As shown, an embodiment of the present invention provides a highly adaptable non-ferrous metal die-casting equipment, including a die-casting equipment body 1, a support 2, and a mounting base 4. The support 2 is fixedly connected to the die-casting equipment body 1. A hydraulic rod 3 is fixedly connected between the mounting base 4 and the support 2. A housing assembly is symmetrically arranged on both sides of the mounting base 4. Multiple spraying rods 21 are arranged in an array on the housing assembly. A cleaning mechanism is provided on the outer side of the spraying rod 21. The cleaning mechanism is used to clean and remove impurities from the mold cavity. The cleaning mechanism includes a mounting cylinder 12, a connecting cylinder 13, and multiple brush plates 35. A limiting ring 26 is fixedly connected to the outer wall of the spraying rod 21. Multiple limiting mechanisms are provided between the connecting cylinder 13 and the limiting ring 26. The limiting mechanisms are used to fix and limit the connection between the connecting cylinder 13 and the spraying rod 21. The limiting mechanisms include a connecting rod 31, a limiting block 32, and a third spring 34.

[0024] like Figures 2 to 5 As shown, the outer casing assembly includes a mounting shell 7, a connecting shell 8, and a mounting plate 9. The connecting shell 8 is fixedly connected between the mounting shell 7 and the mounting plate 9. The mounting cylinder 12 passes through the mounting plate 9 and is rotatably connected to the mounting plate 9. A connecting pipe is connected between the spraying rods 21. A connecting port 11 is fixedly connected to the outer wall of the connecting shell 8, and the connecting port 11 is connected and communicates with the connecting pipe. In use, the device holding the release agent is connected to the connecting port 11. The release agent enters the connecting pipe through the connecting port 11 and is evenly sprayed onto the inner wall of the mold cavity by the nozzle of the spraying rod 21.

[0025] like Figures 5 to 10 As shown, the connecting cylinder 13 is slidably connected to the mounting cylinder 12. Multiple brush plates 35 are arranged in a circle and are rotatably connected to the end of the connecting cylinder 13 by a torsion spring. A driving wheel 18, multiple driven wheels 16, and an idler wheel 17 are rotatably connected to the mounting plate 9. The driven wheels 16 are coaxially fixed to the mounting cylinder 12. The driving wheel 18 and the idler wheel 17 are both meshed between the multiple driven wheels 16. A second motor 19 is fixedly connected to the side of the mounting housing 7 near the mounting plate 9. The output end of the second motor 19 is coaxial with the driving wheel 18. Fixed; during use, the second motor 19 is started to drive the drive wheel 18 to rotate, which in turn drives the driven wheel 16 and idler wheel 17 to rotate, causing all mounting cylinders 12 to rotate synchronously. The connecting cylinder 13 drives the brush plate 35 to rotate at high speed and rub against the inner wall of the mold cavity to remove surface impurities. Under normal conditions, the brush plate 35 is perpendicular to the axis of the connecting cylinder 13. The multiple circumferentially arranged brush plates 35 can seal the end of the connecting cylinder 13, ensuring that the nozzle is completely covered when not in operation, effectively isolating external dust and impurities. When the connecting cylinder 13 moves down and the brush plate 35 contacts the top of the spray bar 21, the spray bar 21 will squeeze the brush plate 35, causing it to overcome the elastic force of the torsion spring and rotate outward to open, thereby exposing the nozzle for mold release agent spraying.

[0026] like Figures 2 to 4As shown, a slide rod 5 and a rack 6 are fixedly connected to the side of the mounting shell 7 away from the mounting plate 9, and both the slide rod 5 and the rack 6 slide through the mounting base 4. A gear 14 is rotatably connected inside the mounting base 4, and the gear 14 meshes with the rack 6. A first motor 15 is fixedly connected to the outer wall of the mounting base 4, and the output end of the first motor 15 is coaxially fixed with the gear 14. When in use, the first motor 15 is started to drive the gear 14 to rotate. The rack 6, which meshes with the gear 14, moves the shell assembly horizontally into the mold cavity under the guidance of the slide rod 5, so that the two symmetrically arranged shell assemblies move in opposite directions. It should be noted that both the first motor 15 and the second motor 19 are connected to an external power source via wires. The external power source includes a battery for providing power to the first motor 15 and the second motor 19 and a control switch for controlling their start and stop. The external power source is existing technology. The specific model and specifications of the first motor 15 and the second motor 19 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts existing technology in this field, so it will not be described in detail.

[0027] like Figure 7 and Figure 8 As shown, the outer wall of the connecting cylinder 13 has multiple mounting slots, and the limiting mechanism is set in the mounting slot. The outer wall of the mounting slot has a through hole, and the limiting block 32 is slidably connected in the through hole. The end of the limiting block 32 is inserted into the limiting ring 26. The side wall of the limiting block 32 has symmetrically fixed protrusions 36. An elastic sheet 37 is fixedly connected between the protrusion 36 and the inner wall of the mounting slot. The connecting rod 31 is slidably connected in the mounting slot and passes through the limiting block 32. The top of the connecting rod 31 is fixedly connected to a slider 33, and the bottom of the connecting rod 31 is fixedly connected to an iron sheet 30. Both the slider 33 and the iron sheet 30 are slidably connected in the mounting slot. Fixed blocks are fixedly connected to both the connecting rod 31 and the inner wall of the mounting slot, and a third spring 34 is fixedly connected between the two fixed blocks. A stop block is fixedly connected in the mounting slot, and the stop block is placed between the slider 33 and the limiting block 32. The limiting block 32 has a rectangular hole with an inclined platform on its inner wall. The connecting rod 31 has a trapezoidal groove with the inclined surface of its side wall fitting against the inclined platform. When the connecting rod 31 moves, the connection between the connecting rod 31 and the limiting block 32 widens, allowing the limiting block 32 to move and separate from the limiting ring 26. Simultaneously, the slider 33 on the connecting rod 31 abuts against the stop block in the mounting groove. As the connecting rod 31 continues to move, the slider 33 presses down on the stop block, causing the connecting cylinder 13 to move against the connecting rod. 31. Synchronous movement. It should be noted that the extension and retraction between the mounting cylinder 12 and the connecting cylinder 13 is sufficient to accommodate mold cavities of different shapes. That is, the brush plate 35 abuts against the inner wall of the mold cavity and drives the spraying rod 21 and the circular plate 22 to compress the first spring 23 to different degrees. When the connecting cylinder 13 is partially retracted into the mounting cylinder 12, the iron plate 30 at the end of the connecting rod 31 and the electromagnet 29 still maintain a certain distance, always providing the conditions for the spraying rod 21 to push open the brush plate 35, thus reserving enough space for the subsequent movement of the connecting cylinder 13.

[0028] like Figure 9 and Figure 10 As shown, an annular groove is provided on the outer wall of the mounting cylinder 12. Multiple electromagnets 29, guide rods 27, and a second spring 28 are fixedly connected in the annular groove. The electromagnets 29 correspond to the positions of the iron plate 30. The second spring 28 is sleeved on the guide rod 27, and the end of the second spring 28 is fixedly connected to the connecting cylinder 13. The end of the guide rod 27 is slidably inserted into the side wall of the connecting cylinder 13. It should be noted that the elastic potential energy of the second spring 28 is much greater than that of the third spring 34. When the third spring 34 and the second spring 28 are in the same direction, the third spring 34 will be stretched first and then the second spring 28 will be compressed. During reset, the compressed second spring 28 will reset first, and the stretched third spring 34 will reset later. Correspondingly, the connecting cylinder 13 resets first, and then the connecting rod 31 resets. At this time, the limiting block 32 is reinserted into the limiting ring 26 with the help of the elastic plate 37, limiting the connection cylinder 13 and the spraying rod 21.

[0029] like Figures 6 to 8 As shown, the mounting shell 7 has multiple sliding grooves. The end of the spraying rod 21 is sequentially fixedly connected to a circular plate 22, a circular rod 25, and a positioning rod 24. The positioning rod 24 is slidably connected in the sliding groove. A first spring 23 is sleeved on the circular rod 25. The two ends of the first spring 23 are fixedly connected to the circular plate 22 and the inner wall of the sliding groove, respectively. A limit frame 20 is slidably connected inside the mounting shell 7. Multiple top blocks are fixedly connected on the limit frame 20. The top blocks correspond to the positions of the positioning rod 24. A cylinder 10 is fixedly connected to the outer wall of the mounting shell 7. The output shaft of the cylinder 10 is fixedly connected to the limit frame 20. When in use, the hydraulic rod 3 is activated to drive the mounting base 4 and the outer casing assembly to move downwards, so that the brush plate 35 enters the mold cavity and contacts the inner wall of the mold cavity. Continuing to move will cause the circular plate 22 at the end of the spraying rod 21 to compress the first spring 23, ensuring that each brush plate 35 can fit tightly against the inner wall of the mold cavity. The driving cylinder 10 drives the limiting frame 20 to move, and the top block on the limiting frame 20 presses and limits the positioning rod 24. It should be noted that the hydraulic rod 3 and the cylinder 10 are both existing technologies. The specific model and specifications of the hydraulic rod 3 and the cylinder 10 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0030] This application also provides another technical solution: a highly adaptable non-ferrous metal die-casting method, the specific steps of which are as follows: S1: Start the first motor 15 to drive the gear 14 to rotate. Under the action of the gear 14, drive the two meshing racks 6 to rotate in opposite directions, thereby driving the outer shell assembly and the cleaning mechanism to move into the mold cavity. S2: The moving brush plate 35 and connecting cylinder 13 abut against the mold cavity. Driven by the reaction force, the connecting cylinder 13 drives the spraying rod 21 to move through the limiting block 32 and the limiting ring 26. The spraying rod 21 drives the positioning rod 24 to move through the round rod 25. At the same time, the round plate 22 compresses the first spring 23. According to the synchronous shape of the inner wall of the mold cavity, the compression degree of the first spring 23 is different, always keeping the brush plate 35 in contact with the inner wall of the mold cavity. At this time, the starting cylinder 10 pushes the limiting frame 20 to move. The top block on the limiting frame 20 squeezes and limits the positioning rod 24. S3: Start the second motor 19 to drive the drive wheel 18 to rotate. The drive wheel 18 drives the meshing driven wheels 16 to rotate. The rotating driven wheels 16 drive the other driven wheels 16 to rotate through the idler wheel 17. This drives the mounting cylinder 12, which is fixed coaxially with the driven wheels 16, to rotate. The mounting cylinder 12 drives the brush plate 35 to rotate on the inner wall of the mold cavity through the connecting cylinder 13 to clean the mold cavity. S4: When electromagnet 29 is energized, electromagnet 29 attracts iron sheet 30 and it comes into contact with it. Iron sheet 30 drives connecting rod 31 to move and stretches third spring 34. During the movement of connecting rod 31, it will push limit block 32 to move, causing limit block 32 limit ring 26 to separate and release the limit on spraying rod 21. At this time, the moving connecting rod 31 drives slider 33 to abut against the stop block. The continuing to move connecting rod 31 will drive connecting cylinder 13 to move, causing it to compress second spring 28. S5: During the downward movement of the connecting cylinder 13, the brush plate 35 gradually approaches the spraying rod 21. The top of the spraying rod 21 will push the moving brush plate 35 open, and then the release agent will be sprayed from the nozzle at the end of the spraying rod 21 onto the inner wall of the mold cavity.

[0031] The working principle of the technical solution provided by this invention is as follows: During operation, the hydraulic rod 3 first drives the mounting base 4 and the outer casing assembly to move downwards as a whole, aligning the cleaning mechanism with the mold cavity entrance of the die-casting equipment body 1. Then, the first motor 15 starts, driving the gear 14 to rotate. The rack 6, meshing with the gear 14, moves the outer casing assembly horizontally into the mold cavity under the guidance of the slide rod 5. When the brush plate 35 contacts the inner wall of the mold cavity, the reaction force pushes the connecting cylinder 13 towards the mounting cylinder 12. The connecting cylinder 13, through the cooperation of the limiting block 32 and the limiting ring 26, drives the spraying rod 21 to move synchronously. The circular plate 22 at the end of the spraying rod 21 compresses the first spring 23, while the positioning rod 24 slides in the groove.

[0032] In addition, since there may be irregular curved surfaces on the inner wall of the mold cavity, the reaction forces on the brush plates 35 at different positions are different. The first spring 23 will adaptively adjust the compression amount according to the pressure to ensure that each brush plate 35 can fit tightly against the inner wall of the mold cavity. At this time, the cylinder 10 drives the limit frame 20 to move, and the top block squeezes the positioning rod 24 to achieve position locking.

[0033] In addition, the second motor 19 starts, and the driving wheel 18 drives the driven wheel 16 and idler wheel 17 to rotate, so that all the mounting cylinders 12 rotate synchronously. The connecting cylinder 13 drives the brush plate 35 to rotate and rub at high speed on the inner wall of the mold cavity to remove surface impurities. After cleaning, the electromagnet 29 is energized to generate magnetic force to attract the iron plate 30. The iron plate 30 pulls the connecting rod 31 to stretch the third spring 34. The connecting rod 31 pushes the limit block 32 to compress the elastic plate 37 and disengage from the limit ring 26. After the slider 33 contacts the stop block, the connecting rod 31 continues to drive the connecting cylinder 13 to compress the second spring 28 and move it down. The brush plate 35 opens up under the resistance of the top of the spraying rod 21, overcoming the torsion spring force. Finally, the release agent enters the connecting pipe through the connecting port 11 and is evenly sprayed on the inner wall of the mold cavity through the nozzle of the spraying rod 21. The whole process realizes the automated and continuous operation of cleaning and spraying.

[0034] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.

10. A highly adaptable non-ferrous metal die-casting method, applicable to the highly adaptable non-ferrous metal die-casting equipment described in claim 9, characterized in that, The specific steps are as follows: S1: Start the first motor (15) to drive the gear (14) to rotate. Under the action of the gear (14), the two meshing racks (6) are driven to rotate in opposite directions, thereby driving the outer shell assembly and the cleaning mechanism to move into the mold cavity; S2: The moving brush plate (35) and connecting cylinder (13) abut against the mold cavity. Driven by the reaction force, the connecting cylinder (13) drives the spraying rod (21) to move through the limiting block (32) and the limiting ring (26). The spraying rod (21) drives the positioning rod (24) to move through the round rod (25). At the same time, the round plate (22) compresses the first spring (23). According to the synchronous shape of the inner wall of the mold cavity, the compression degree of the first spring (23) is different, and the brush plate (35) is always kept in contact with the inner wall of the mold cavity. At this time, the cylinder (10) is started to push the limiting frame (20) to move. The top block on the limiting frame (20) squeezes and limits the positioning rod (24). S3: Start the second motor (19) to drive the drive wheel (18) to rotate. The drive wheel (18) drives the meshing driven wheels (16) to rotate. The rotating driven wheels (16) drive the remaining driven wheels (16) to rotate through the idler wheel (17). This drives the mounting cylinder (12) which is coaxially fixed with the driven wheels (16) to rotate. The mounting cylinder (12) drives the brush plate (35) to rotate on the inner wall of the mold cavity through the connecting cylinder (13) to clean the mold cavity. S4: When the electromagnet (29) is energized, the electromagnet (29) attracts the iron sheet (30) and it comes into contact with the iron sheet (30). The iron sheet (30) drives the connecting rod (31) to move and stretches the third spring (34). During the movement of the connecting rod (31), it will push the limiting block (32) to move, causing the limiting ring (26) of the limiting block (32) to separate and release the limitation on the spraying rod (21). At this time, the moving connecting rod (31) drives the slider (33) to abut against the stop block. The continuing to move connecting rod (31) will drive the connecting cylinder (13) to move, causing it to compress the second spring (28). S5: During the downward movement of the connecting cylinder (13), the brush plate (35) gradually approaches the spray bar (21). The top of the spray bar (21) will push the moving brush plate (35) open, and then the release agent will be sprayed from the nozzle at the end of the spray bar (21) onto the inner wall of the mold cavity.
