Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting mechanical equipment, in particular to a shell cleaning device used in investment casting. Background Art
[0002] Casting machinery is the equipment used in the casting process to pour molten metal into a mold to form a casting. These machines are designed in various types, depending on the casting process and production requirements. In investment casting, shell removal equipment is primarily used to remove the ceramic shell layer on the casting surface to obtain the final casting.
[0003] When using existing shell cleaning equipment, the casting is first placed on a vibrating platform. Compressed air is supplied by an air compressor and piped to the vibrator's cylinder. Once the compressed air enters the cylinder, it drives the piston inside, driving the vibrator to generate high-frequency vibrations. This high-frequency vibration is transmitted to the surface of the casting, subjecting the ceramic shell to periodic mechanical stress. Due to the brittleness of the ceramic shell, this mechanical stress can cause microcracks in the shell, ultimately leading to breakage and shedding.
[0004] Although existing shell cleaning equipment can complete the shell cleaning operation of castings, it cannot fix the castings when they are placed on the vibration platform. The castings will shift or slide due to the vibration force during the vibration process, resulting in uneven shell cleaning effect. Some areas may not be cleaned properly, while other parts may be subjected to excessive vibration, making it impossible for the ceramic shell layer in some parts to fall off effectively, affecting the final cleaning effect.

[0024] The following will be combined with the 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.
[0025] Reference Figure 1 、 Figure 2 and Figure 4 , the utility model provides an embodiment: a shell cleaning device for investment casting, including a bracket 1, both sides of the upper part of the bracket 1 are fixedly connected to fixed blocks 5, the two fixed blocks 5 are fixedly connected to the outside of a U-shaped frame 6, a shell cleaning component 7 is provided on the outside of the U-shaped frame 6, and the shell cleaning component 7 is used for the shell cleaning operation of the casting, the inside of the U-shaped frame 6 is fixedly connected to a horizontal plate 8, the outside of the horizontal plate 8 is fixedly connected to an electric push rod 9, the output end of the electric push rod 9 is fixedly connected to a moving block 10, the outside of the moving block 10 is rotatably connected to a first adjusting plate 11, the inside of the horizontal plate 8 is fixedly connected to a fixed rod 12, the outside of the two fixed rods 12 are slidably connected to a slider 13, the two The other end of the first adjustment plate 11 is rotatably connected to the outside of the two sliders 13, and the outside of the two sliders 13 are rotatably connected to the second adjustment plate 15. The other ends of the two second adjustment plates 15 are rotatably connected to the mounting plate 17, and the outside of the mounting plate 17 is fixedly connected to the clamping plate 18. The shell cleaning component 7 includes a cylinder 701, which is installed on the outside of the U-shaped frame 6. The output end of the cylinder 701 is fixedly connected to the vibrating body 702. Through holes 14 are opened on both sides of the inside of the cross plate 8, and the two fixing rods 12 are fixedly connected to the inside of the two through holes 14. The front side of the outside of the cross plate 8 is fixedly connected to the telescopic rod 16, and the top of the telescopic rod 16 is fixedly connected to the outside of the mounting plate 17.
[0026] When performing shell cleaning on a casting, the casting must first be placed in the upper center of the bracket 1. Next, the electric push rod 9 is activated. A movable block 10 is attached to the output end of the push rod 9. As the push rod 9 is activated, the movable block 10 begins to move. The movement of the movable block 10 drives the first adjustment plates 11, which are pivotally connected to the outside, to move together. As the two first adjustment plates 11 move, they also drive the two sliders 13, pivotally connected to their other ends, to move relative to each other. The relative movement of the sliders 13 further drives the two second adjustment plates 15, pivotally connected to the outside, to move relative to each other. As the two second adjustment plates 15 move relative to each other, they also drive the mounting plates 17, pivotally connected to their other ends, to move together. The movement of the mounting plates 17 directly affects the position of the clamping plates 18 fixed to their outside. As the mounting plates 17 move, the two clamping plates 18 gradually approach the casting and contact its outer surface, firmly securing it. This securement method effectively maintains the stability of the casting during shell cleaning, preventing it from moving or shaking during vibrations. This ensures consistency during the shell cleaning process. By securely securing the casting to the bracket 1, potential displacement or sliding of the casting during vibration is prevented, thereby avoiding uneven shell cleaning or residual residue. This not only improves the efficiency and effectiveness of shell cleaning but also ensures the quality of the cleaning of the casting surface. Furthermore, the fixture can accommodate castings of varying sizes and shapes. By adjusting the first adjustment plate 11 and the second adjustment plate 15, the clamping plate 18 can be ensured to accurately contact the casting surface, achieving a secure fixation. This flexibility and adaptability enable the shell cleaning equipment to be widely used in shell cleaning operations on a variety of castings, further enhancing its practicality and reliability.
[0027] Reference Figure 3 The rear side of the upper part of the bracket 1 is fixedly connected to an extension plate 19, and a motor 21 is provided at the lower part of the extension plate 19. The output end of the motor 21 is fixedly connected to a turntable 22, and a connecting rod 23 is rotatably connected to the upper part of the turntable 22. The other end of the connecting rod 23 is fixedly connected to a connecting plate 24, and a scraper 25 is installed at the lower part of the connecting plate 24. Guide blocks 26 are fixedly connected on both sides of the outside of the connecting plate 24. The lower part of the extension plate 19 is fixedly connected to a support plate 20, and the motor 21 is fixedly connected to the upper part of the support plate 20. The two fixed blocks 5 are fixedly connected to the inside of the two fixed blocks 5. The two guide blocks 26 are slidably connected to the outside of the two guide rods 27. A collecting box 2 is provided at the lower part of the bracket 1, and a drawer 3 is slidably connected to the inside of the collecting box 2. A blanking hole 4 is opened at the upper part of the bracket 1.
[0028] After the shell cleaning operation is complete, the casting is removed from the upper portion of the bracket 1. Next, the motor 21 is started, driving the turntable 22 fixed to its output end to begin rotating. As the turntable 22 rotates, the connecting rod 23 connected to it also moves. One end of the connecting rod 23 is fixed to the turntable 22, and the other end is connected to the connecting plate 24. Therefore, the movement of the connecting rod 23 drives the connecting plate 24 to move. The movement of the connecting plate 24 further drives the scraper 25 mounted below it. The scraper 25, through its structure fixed to the connecting plate 24, contacts and cleans the upper portion of the bracket 1. Under the push of the scraper 25, the remaining ceramic shell layer on the upper portion of the bracket 1 is gradually pushed by the scraper 25 toward the discharge hole 4. When the remaining ceramic shell layer reaches the discharge hole 4, it falls into the collection box 2 located at the lower portion of the bracket 1 due to gravity. This process effectively cleans and collects the remaining ceramic shell layer on the upper portion of the bracket 1. The movement of the scraper 25 ensures that the surface of the upper portion of the support 1 remains clean and free of residual ceramic shells. This not only keeps the work area tidy and reduces the accumulation of dust and debris, but also improves the efficiency and quality of the entire shell cleaning process.
[0029] Working principle: When cleaning the shell of a casting, first, place the casting on the upper middle part of the bracket 1, then start the electric push rod 9, the electric push rod 9 moves with the moving block 10 fixed at the output end, the moving block 10 moves with the first adjusting plates 11 connected to the two sides of the outside rotationally, the two first adjusting plates 11 move with the two sliders 13 connected to the other end rotationally moved relative to each other, the two sliders 13 move relative to each other with the two second adjusting plates 15 connected to the outside rotationally, the two second adjusting plates 15 move relative to each other with the mounting plate 17 connected to the other end rotationally moved, the mounting plate 17 moves with the external fixed clamping plate 18 to make the two clamping plates 18 contact the outside of the casting, so that when cleaning the shell of the casting, it is convenient to fix the casting that needs to be cleaned, and fixation can ensure consistency in the shell cleaning process to avoid damage caused by movement or shaking of the casting. The shell cleaning is uneven or residual, ensuring the quality of shell cleaning. After the shell cleaning of the casting is completed, the casting is removed from the upper part of the bracket 1, and then the motor 21 is started. The motor 21 drives the turntable 22 fixed at the output end to rotate, and the turntable 22 rotates to drive the upper rotating connecting rod 23, and the connecting rod 23 moves to drive the connecting plate 24 fixed at the other end to move, and the connecting plate 24 moves to drive the scraper 25 installed at the lower part to move. The movement of the scraper 25 pushes the remaining ceramic shell layer on the upper part of the bracket 1 to the position of the discharge hole 4, and then falls into the collection box 2 set at the lower part of the bracket 1 through the discharge hole 4, so that after the casting is cleaned, it is convenient to clean and collect the ceramic shell remaining on the upper part of the bracket 1. Cleaning and collecting the residual ceramic shell can keep the working area tidy, reduce the accumulation of dust and debris, and help maintain a clean production environment.
