Description
Technical Field
[0001] The utility model relates to the technical field of casting process equipment, in particular to an automatic coating device for V-method casting. Background Art
[0002] V-method casting, also known as negative pressure casting, is a casting process that uses a plastic film to seal a sand box and removes the air inside the mold through a vacuum exhaust system to form the desired cavity. Compared with traditional sand casting, V-method casting does not use adhesives and has the advantages of high production efficiency, high casting precision, and low environmental pollution. However, due to the special structure of some parts, the cavity cannot be formed in one go when making the cavity, which increases the processing difficulty. In order to simplify the process flow of complex cavities, improve production efficiency, and reduce processing difficulty, automated film covering devices for V-method casting have come into being.
[0003] In V-method casting, the film can play a sealing role. By covering the surface of the sand mold with a plastic film, air can be effectively prevented from entering the sand mold, thereby forming a negative pressure when vacuuming, making the sand mold compact and ensuring the strength and stability of the mold. Secondly, the film can make the mold surface smooth, which helps to improve the surface quality of the casting. Finally, the film can isolate the molding sand and the molten metal, avoiding direct contact between the molding sand and the high-temperature molten metal, preventing the molding sand from sintering and mixing into the molten metal, thereby improving the purity of the casting;

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Example 1:
[0033] Reference Figure 1 、 Figure 2 and Figure 3The present invention provides an embodiment of an automatic laminating device for V-method casting, comprising a base 1, which is used to carry the main body of the equipment and provides installation and operation space for various components on the top. A mold 2 is fixedly connected to the top of the base 1, and the mold 2 is used to cast a workpiece. A cylinder 3 is fixedly connected inside the base 1, and an output end of the cylinder 3 is fixedly connected to a connecting shell 4. The cylinder 3 is used to push the connecting shell 4 above the mold 2 to prepare for laminating. A rotating drum 20 is rotatably connected inside the connecting shell 4, and a film roll 5 is fixedly connected to the outer wall of the rotating drum 20. When laminating, the film roll 5 rotates to stretch the film. A motor 6 is fixedly connected inside the connecting shell 4 to provide power for the laminating work. The output end of the motor 6 is fixedly connected to a driving sprocket 7, and a driven sprocket 8 is rotatably connected inside the connecting shell 4. A chain 9 is provided between the driving sprocket 7 and the driven sprocket 8. The chain 9 is used to make the driven sprocket 8 rotate when the driving sprocket 7 rotates. The wall is fixedly connected with a rotating column 10 on one side. When the driving sprocket 7 and the driven sprocket 8 rotate, the rotating column 10 is driven to rotate. A curved groove 11 is provided inside the rotating column 10. The connecting shell 4 is slidably connected with a slide groove 12. The rotating column 10 is slidably connected with a sliding block 13. Through the rotation of the rotating column 10, the film can cover the entire mold 2. The outer wall of the sliding block 13 is slidably connected to the curved groove 11. The sliding block 13 is slidably connected to the connecting column 14. The slide groove 12 allows the film to cover the mold 2. One side of the outer wall of the connecting column 14 is fixedly connected to the connecting shell 2. The connecting shell 2 15 is fixedly connected to the inside of the connecting shell 2. The output end of the cylinder 2 17 is fixedly connected to the clamping block 16. The cylinder 2 17 drives the clamping block 16 to clamp the film to drive the film to cover the mold 2. The connecting shell 4 is fixedly connected to the inside of the cylinder 3 18. The output end of the cylinder 3 18 is fixedly connected to the cutter 19, which is used to remove the film after the lamination is completed.
[0034] Specifically: When using the V-method casting automatic laminating device for the casting process, first start the cylinder 13. The start of the cylinder 13 will push the right side of the connecting shell 14 a certain distance. This action is the starting step of the entire laminating process, ensuring that the film can be correctly placed on the mold 2. Then start the cylinder 2 17. The start of the cylinder 2 17 will drive the clamp 16 to clamp the film. The clamp 16 is designed to ensure that the film remains stable during the movement to prevent sliding or wrinkling during the laminating process. Then start the motor 6. The start of the motor 6 will cause the driving sprocket 7 to rotate, and the rotation of the driving sprocket 7 drives the driven sprocket 8 to rotate through the chain 9. When the driving sprocket 7 and the driven sprocket 8 rotate, the corresponding rotating column 10 is rotated. The rotation of the rotating column 10 is the key step to achieve the movement of the film. It converts the rotary motion into linear motion through mechanical linkage. When the rotating column 10 rotates, the cylinder on the outer wall of the sliding block 13 will move along the slide groove 12 under the action of the curved groove 11 to ensure that the film can be evenly covered on the mold 2. When the groove 12 ends, the connecting shell 2 15 will move downward for a distance to cover the mold 2 with the film. This action ensures that the film can completely cover the mold 2 and prepare for the subsequent casting process. Finally, the cylinder 3 18 is started to make the cutter 19 cut the film. Through such an automated coating device, air can be effectively prevented from entering the sand mold, thereby forming a negative pressure when vacuuming, making the sand mold compact, ensuring the strength and stability of the casting mold, and significantly improving the efficiency and accuracy of V-method casting, meeting the needs of modern industry for high-precision casting parts.
[0035] Example 2:
[0036] Reference Figure 1 and Figure 4The self-locking assembly includes a worm 22 and a worm wheel 23. The worm 22 is meshed with the worm wheel 23. One side of the outer wall of the worm 22 is rotatably connected to the inside of the worm 22. Both sides of the outer wall of the worm wheel 23 are rotatably connected to the inside of the worm 22. The worm 22 and the worm wheel 23 are not only used for transmission, but also for locking the parts inside the drum 20. One side of the outer wall of the worm 22 is fixedly connected to the knob 21. The knob 21 is the power source for the movement of the parts inside the drum 20. The drum 20 is slidably connected with a toothed plate 24. The rotational motion is converted into linear motion through the worm wheel 23 to drive the toothed plate 24 to move. The toothed plate 24 is meshed with the worm wheel 23. One side of the outer wall of the toothed plate 24 is fixedly connected to a connecting column 25. The connecting column 25 is a transmission component for supporting the film roll 5. A clamping block 27 is slidably connected to the inside of the rotating drum 20. The clamping block 27 is used to support the film roll 5. The outer wall of the clamping block 27 is fixedly connected to the inside of the film roll 5. The bottom of the clamping block 27 is rotatably connected to the transmission rod 26. The bottom of the transmission rod 26 is rotatably connected to the top of the connecting column 25. The transmission rod 26 is used to drive the clamping block 27 to support the film roll 5. The outer wall of the rotating drum 20 is fixedly connected to the limit plate 28. The limit plate 28 is slidably connected to the inside of the limit plate 28. One side of the outer wall of the slider 29 is fixedly connected to one side of the outer wall of the clamping block 27. The limit plate 28 is used to guide the movement of the clamping block 27 to prevent the clamping block 27 from deviating from its route when moving.
[0037] Specifically: When the film roll 5 needs to be replaced, first turn the knob 21. The knob 21 is the starting point of the entire replacement process. Its design allows the user to control the rotation of the worm 22 through a simple rotation action. The rotation of the worm 22 is a key step in achieving the replacement of the film roll 5. It converts the rotational motion into linear motion through mechanical linkage. The rotation of the worm 22 forces the worm gear 23 to rotate. The rotation of the worm gear 23 is a key step in converting the rotational motion into linear motion through mechanical linkage. The rotation of the worm gear 23 drives the tooth plate 24 to move to the lower left. The movement of the tooth plate 24 forces the connecting column 25 to rotate multiple transmission rods 26. The transmission rod 26 converts the rotational motion into linear motion through mechanical linkage. The rotation of the transmission rod 26 cooperates with the slider 29 and the limit plate 28, so that the clamp block 27 is forced to gather toward the connecting column 25. The gathering of the clamp block 27 is a key step in releasing the internal support of the film roll 5. When the clamp block 27 moves toward the connecting column 2 When 25 is gathered, the inner support of the film roll 5 is released. After the inner support is released, the film roll 5 can be easily removed for necessary replacement. The component is optimized in the installation and disassembly methods of the film roll 5, making the operation of replacing the film roll 5 simpler and faster, reducing the replacement time and labor costs, and improving production efficiency. In the automatic coating device for V-method casting, the advantage of using the worm 22 and the worm wheel 23 is that the self-locking function of the worm 22 and the worm wheel 23 can make the components remain stable after being adjusted to a specific position, and will not change position due to external force or vibration.
[0038] Working principle: When using the V-method casting automatic laminating device, first start the cylinder 13 to push the right side of the connecting shell 14 for a distance, then start the cylinder 2 17 to drive the clamping block 16 to clamp the film, then start the motor 6, the motor 6 drives the driving sprocket 7 to rotate, and then the driving sprocket 7 drives the driven sprocket 8 to rotate through the chain 9. When the driving sprocket 7 and the driven sprocket 8 rotate, they respectively drive the corresponding rotating column 10 to rotate. When the rotating column 10 rotates, the cylinder on the outer wall of the sliding block 13 will move along the slide groove 12 under the action of the curved groove 11, so that the film is driven to move toward the mold 2 through the connecting shell 2 15. When it reaches the slide, the film is driven to move toward the mold 2. When the groove 12 ends, the connection shell 2 15 cooperates with the connecting column 1 14 to drive the film to move downward for a distance to cover the mold 2, and then the cylinder 3 18 is started to drive the cutter 19 to cut the film. When the film roll 5 needs to be replaced, the knob 21 is first turned. The knob 21 drives the worm 22 to rotate, so that the tooth plate 24 is driven to move to the lower left through the worm gear 23, so that the connecting column 25 is forced to drive multiple transmission rods 26 to rotate, and then the slider 29 and the limit plate 28 cooperate to make the clamping block 27 forced to gather toward the connecting column 25 to release the internal support of the film roll 5. After the release, the film roll 5 can be removed for necessary replacement.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
