Description

Technical Field

[0001] This utility model relates to the field of coated sand recycling technology, specifically a coated sand recycling device for a core shooter. Background Technology

[0002] In industrial casting production, the casting process is mostly used, where molten metal is poured into a sand mold for casting. Most existing sand molds are manufactured using a core shooter, which has an upper and lower mold. During sand mold production, coated sand is injected into the upper and lower molds to form a cavity, which is then heated to complete the sand mold production.

[0003] However, during the operation of a core shooter, some sand particles fall onto the surface of the lower mold. When the upper and lower molds close, most existing core shooters require manual blowing to remove the sand particles, as they cannot be recycled. This results in sand waste, and the sand falling to the ground creates waste in the workshop, affecting cleanliness, making cleaning difficult, and causing inconvenience to workers. Therefore, we propose a core shooter coated sand recycling device. Utility Model Content

[0004] In view of the fact that existing core shooting machines generally require manual blowing off of sand particles, which cannot be recycled and reused, resulting in the waste of sand particles, this utility model provides a core shooting machine coated sand recycling device, which can adsorb coated sand into a collection box for collection and recycling, ensuring the full recycling and collection of coated sand, and solving the problems mentioned in the background art.

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

[0021] Reference Figures 1 to 4This utility model provides a technical solution: a core-shooting machine coated sand recovery device, including a frame 23, a mounting frame 3 fixedly connected to the top of the frame 23, and a sand storage mechanism connected to the top of the mounting frame 3. The sand storage mechanism includes a sand storage tank 22, with connecting seats 2 symmetrically connected to the outer wall of the sand storage tank 22. A first electric push rod 1 is vertically connected to the top of the connecting seat 2, connecting the first electric push rod 1 to the top of the mounting frame 3. A sliding groove 21 is formed on the side wall of the mounting frame 3, and a slider 20 is connected to the end of the connecting seat 2, slidingly connecting the slider 20 and the sliding groove 21. Figure 1 , 2 As shown, under the extension and retraction of the first electric push rod 1, the sand storage tank 22 can be driven to move up and down rapidly inside the mounting frame 3, thereby enabling normal sand discharge operation.

[0022] like Figure 3 As shown, a processing mechanism connected to the mounting frame 3 is set directly below the sand storage mechanism. The processing mechanism includes two symmetrically arranged molds 19. The top of the mold 19 has a sand inlet hole 18. The sand outlet at the bottom of the sand storage tank 22 corresponds to the sand inlet hole 18. The outer wall of each mold 19 is connected to a second electric push rod 5, and the second electric push rod 5 is connected to the mounting frame 3. In order to realize the rapid demolding after the mold 19 is processed, the outer wall of one of the molds 19 is rotatably connected to the free end of the second electric push rod 5 through the hinge seat 28. A support seat 4 is supported on the second electric push rod 5. A third electric push rod 6 is rotatably connected between the support seat 4 and the outer wall of the mold 19. Under the push of the third electric push rod 6, one of the molds 19 can be rotated. The rotated mold 19 facilitates the rapid demolding of the processed parts.

[0023] like Figure 3 As shown, an opening is provided at the top of the frame 23 directly below the processing mechanism, and the bottom of the opening is connected to the collection hopper 29. An installation frame 31 is provided inside the opening and is telescopically connected to the collection hopper 29. Multiple transport rollers 10 are rotatably connected inside the installation frame 31, and a fifth electric push rod 12 is fastened to the bottom of the collection hopper 29. The telescopic end of the fifth electric push rod 12 is connected to the bottom of the installation frame 31. Multiple sets of guide tubes 32 are vertically connected between the bottom surface of the collection hopper 29 and the bottom of the installation frame 31. Each set of guide tubes 32 consists of two tubes, and the two guide tubes 32 are coaxially slidably connected. The fifth electric push rod 12 pushes the installation frame 31 to move upward. At this time, after the mold 19 is flipped, the processed part falls to the top of the transport rollers 10. During demolding, the waste coated sand can fall into the collection hopper 29 for collection and recycling. At the same time, the integrity of the processed part can be ensured by the support of the transport rollers 10.

[0024] like Figure 2 , 4As shown, in order to further collect and recycle the coated sand quickly, a blower 27 is connected to one side of the collection hopper 29 via a connecting pipe 26, and the blower 27 is connected to the collection box 25. The top of the collection box 25 is sealed with a sealing cover 24. A filter screen 14 is connected inside the collection box 25. The lower end of the frame 23 is fastened to the base 13. The fifth electric push rod 12 is connected to the base 13. The bottom of the collection hopper 29 is connected to the base 13 via a support 11. The collection box 25 and the blower 27 are both located on top of the base 13.

[0025] In summary, the core-shooting machine coated sand recovery device, during use, has a push plate 9 installed on one side of the frame 23. The outer wall of the push plate 9 is horizontally connected to a fourth electric push rod 8, which in turn connects to the top of the frame 23. The push plate 9 slides on top of the conveyor roller 10 under the push of the fourth electric push rod 8. A guide rod 7, parallel to the fourth electric push rod 8, is tightly fastened to the outer wall of the push plate 9. The guide rod 7 is slidably connected to the top of the frame 23 via a guide seat. Several brush bristles 30 are also fastened to the bottom of the push plate 9. The processing part position... After being placed on top of the conveyor roller 10, the machine returns to its initial position under the action of the fifth electric push rod 12. Under the push of the fourth electric push rod 8, the push plate 9 can be driven to push the workpiece. At the same time, under the cleaning action of the brush 30, the waste coated sand can be swept into the collection hopper 29, which greatly facilitates recycling. In addition, to further facilitate the unloading of the workpiece, a mounting platform 17 is connected to the side of the frame 23 away from the push plate 9. A conveyor belt 16 driven by a motor 15 is rotatably connected inside the mounting platform 17.
