[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example 1

[0023] This utility model provides a sand removal device for hardware castings, such as Figures 1 to 6 As shown, the system includes a housing 1, a door 2, and a partition plate 3. Inside the housing 1, below the partition plate 3, a workbench 4 is installed. A cylinder 5 is fixedly installed at the top of the partition plate 3. A slider 6 is fixedly connected to the output end of the cylinder 5. A rack 7 is fixedly connected to one side of the slider 6. A gear 8 is rotatably connected to the center of the bottom end of the partition plate 3. A slider 9 is slidably installed inside the partition plate 3. A rack 10 is fixedly connected to one side of the slider 9. The outer surfaces of rack 7 and rack 10 are meshed with the outer surface of gear 8. Sand-falling air hammers 12 are installed at the bottom ends of both slider 6 and slider 9. By activating the cylinder 5, the sand-falling air hammers 12 are driven to... The movable slider 6 slides inside the partition plate 3. When slider 6 slides, it drives rack 7 to slide laterally. When rack 7 slides, it drives gear 8 to rotate. When gear 8 rotates, it drives rack 10 to slide laterally through meshing. The sliding directions of rack 7 and rack 10 are opposite. When rack 10 slides, it drives slider 9 to slide inside the partition plate 3. Thus, when cylinder 5 is working, slider 6 and slider 9 move closer or further apart, thereby adjusting the distance between the two sand-falling air hammers 12. This facilitates the pressing and high-frequency vibration of metal castings of different sizes and shapes, improving the working efficiency of the device.

[0024] like Figure 3 and Figure 4 As shown, two fixing posts 11 are symmetrically fixed between the inner walls of the housing 1. Both fixing posts 11 penetrate the slider 6 and slider 9. The inner walls of slider 6 and slider 9 are provided with through holes corresponding to the outer sides of the two fixing posts 11, so that the inner walls of the through holes of slider 6 and slider 9 fit against the outer surface of the fixing posts 11. When slider 6 and slider 9 move, the inner walls of the through holes of slider 6 and slider 9 are supported by the outer surface of the fixing posts 11, thereby effectively ensuring the stability of slider 6 and slider 9 during movement.

[0025] like Figure 2 and Figure 5 As shown, a guide frame 13 is fixedly installed at the bottom of the workbench 4, and a collection box 14 is slidably installed at the bottom of the guide frame 13. The inside of the guide frame 13 is set as an inclined surface, so that the sand and dust falling from the surface of the metal casting falls down along the inclined surface of the guide frame 13 into the inside of the collection box 14, thereby achieving effective collection and removal of sand and dust, preventing sand and dust from falling directly to the ground, and reducing the workload of the workers.

[0026] like Figure 5 and Figure 6As shown, a locking post 15 is slidably installed inside the guide frame 13. A locking block 16 is integrally formed on the outer surface of the locking post 15. A locking groove 17 is provided inside the guide frame 13 at the outer position corresponding to the locking block 16. A mating hole is provided inside the guide frame 13 at the outer bottom end corresponding to the locking post 15. When the collection box 14 is slidably installed to the bottom end of the guide frame 13, the locking post 15 is rotated so that the locking block 16 engages with the inside of the locking groove 17. At this time, the opposite surfaces of the collection box 14 and the locking post 15 are in contact with each other, so that the collection box 14 is locked. At the bottom of the guide frame 13, ensure that the collection box 14 is fixed at the bottom of the guide frame 13 during operation to prevent it from slipping out. When it is necessary to remove the collection box 14 from the bottom of the guide frame 13, rotate the locking block 16 to disengage it from the locking slot 17, and then push the locking block 16 upward to drive the locking post 15 to slide upward, so that the bottom of the locking post 15 is higher than the top of the collection box 14, so that the opposite surfaces of the collection box 14 and the locking post 15 no longer contact each other, so that the collection box 14 is no longer stuck, and then the collection box 14 can be pulled out.

[0027] Working principle: During use, the operator places the metal casting to be desanded on the workbench 4. Depending on the size of the casting to be desanded, the cylinder 5 is activated, causing the slider 6 to slide inside the partition plate 3. When the slider 6 slides, it drives the rack 7 to move laterally. When the rack 7 moves, it drives the gear 8 to rotate through meshing. When the gear 8 rotates, it drives the rack 10 to move laterally through meshing. The racks 7 and 10 move in opposite directions, causing the sliders 6 and 9 to move closer or further apart, thereby adjusting the distance between the two sand-falling air hammers 12. Then, the baffle 2 is pulled out to the workbench 4 area to prevent sand and dust from flying out during the desanding of the casting. By activating the sand-falling air hammers 12, the casting is desanded. This device is suitable for high-frequency vibration desanding of metal castings of different sizes, thus expanding its applicability.

[0028] The metal castings vibrate under the sand-falling air hammer 12, causing the sand and dust on the surface of the castings to fall off. The fallen sand and dust fall down the inclined surface of the guide frame 13 into the collection box 14, which facilitates the collection and treatment of the sand and dust, prevents the sand and dust from falling directly to the ground, reduces the workload of the workers, slows down environmental pollution, and ensures the cleanliness of the working environment.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
