Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically to a casting sand spreading device for sand casting. Background Technology

[0002] Sand casting is a casting method that produces castings in sand molds. Steel, iron, and most non-ferrous alloy castings can be obtained using sand casting. Because the molding materials used in sand casting are inexpensive and readily available, and mold making is simple, sand casting requires the spreading of the casting sand.

[0003] Traditional paving mechanisms have certain shortcomings in use. During paving, foundry sand adheres to the surface of the screed plate. If the foundry sand on the surface of the screed plate cannot be removed in time, it will affect the normal use of the screed plate next time. At the same time, the leveling by hand during use will also reduce the leveling quality of foundry sand. Therefore, we have proposed a foundry sand paving device for sand casting.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0024] A sand spreading device for sand casting includes a base plate 1, a first cylinder 5 mounted on the side of the base plate 1, a connecting plate 6 fixedly connected to the side of the first cylinder 5, a brush 7 fixedly connected to the inner wall of the connecting plate 6, a top plate 8 fixedly connected to the top of the base plate 1, a movable plate 11 slidably connected inside the top plate 8, a positioning sensor 12 fixedly connected to the top of the movable plate 11, a rectangular plate 18 fixedly connected to the bottom of the movable plate 11, an infrared probe 19 fixedly connected to the bottom surface of the rectangular plate 18, a second cylinder 17 fixedly connected to the bottom of the rectangular plate 18, a scraper plate 16 fixedly connected to the bottom of the second cylinder 17, and the infrared probe 19 and the scraper plate 16 being positioned opposite each other.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, a rack 13 is fixedly connected to the side of the moving plate 11, and a drive motor 14 is installed on the side of the top plate 8. A gear 15 is fixedly connected to the output end of the drive motor 14. The gear 15 is located on the side of the rack 13. When the infrared sensor 19 detects casting sand on the surface of the scraper plate 16, it transmits the information to the control board 9, causing the drive motor 14 to drive the gear 15 to rotate continuously in the forward direction, thereby moving the rack 13, the moving plate 11, and the scraper plate 16 to the side of the connecting plate 6. The positioning sensor 12 positions the scraper plate 16. The gear 15 meshes with the rack 13. Both the gear 15 and the rack 13 are made of stainless steel. A casting box 3 is fixedly connected to the surface of the bottom plate 1, and a collection box 4 abuts against the surface of the bottom plate 1. The casting box 3 is located directly below the scraper plate 16 and is rectangular in shape.

[0026] The surface of the scraper plate 16 can be monitored by the infrared probe 19. When casting sand is present, the scraper plate 16 is moved to the side of the connecting plate 6 under the action of the control plate 9, which in turn drives the connecting plate 6 and the brush 7 to move and scrape off the casting sand on the surface of the scraper plate 6. The cleanliness of the surface of the scraper plate 16 makes it easier for the scraper plate 16 to be used normally next time.

[0027] In this embodiment, as Figure 3 and Figure 4 As shown, a control board 9 and a battery box 10 are fixedly connected to the top of the top plate 8. The positioning sensor 12 and the infrared probe 19 are electrically connected to the control board 9. The control board 9 is electrically connected to the drive motor 14, the first cylinder 5, and the second cylinder 17. A support base 2 is fixedly connected to the bottom of the bottom plate 1. The support base 2 is made of stainless steel and has anti-slip texture on its bottom. Multiple brushes 7 are provided, and the multiple brushes 7 are evenly distributed in the connecting plate 6. The multiple brushes 7 are all the same size. Two infrared probes 19 are provided. The two infrared probes 19 are respectively located on both sides of the second cylinder 17. The two infrared probes 19 are of the same model.

[0028] The scraper plate 16 can be driven to circulate within the casting box 3. The movement of the scraper plate 16 can spread the casting sand within the casting box 3, avoiding manual operation and improving the uniformity of the casting sand spreading.

[0029] The working process of this utility model is as follows: When the sand casting sand spreading device designed in this scheme is in operation, the scraper plate 16 moves downward under the action of the second cylinder 17, so that the scraper plate 16 contacts the casting sand. Then, under the action of the drive motor 14, the gear 15 rotates in both directions. Through the meshing action of the gear 15 and the rack 13, the scraper plate 16 moves, thereby smoothing the casting sand. When the infrared probe 19 detects casting sand on the surface of the scraper plate 16, it transmits the information to the control board 9, so that the drive motor 14 drives the gear 15 to rotate continuously in the forward direction, thereby moving the rack 13, the moving plate 11 and the scraper plate 16 to the side of the connecting plate 6. The positioning sensor 12 positions the scraper plate 16. Then, under the action of the first cylinder 5, the connecting plate 6 and the brush 7 move, scraping off the casting sand on the surface of the scraper plate 16, improving the cleanliness of the scraper plate 16 surface, and facilitating the normal use of the scraper plate 16 next time.
