Description

Technical Field

[0001] This utility model relates to the field of sand mold spraying technology, and in particular to a sand mold spraying device. Background Technology

[0002] Sand casting is a casting method that produces castings in sand molds. A sand box containing the mold is filled with sand, and molten metal is poured into the mold through a pouring cup. The molten metal cools in the sand mold, forming the casting. Sand boxes are typically divided into an upper sand box and a lower sand box, which are joined together to form a sealed cavity. Before pouring molten metal into the sand mold, the inner wall of the mold needs to be coated. This coating serves two purposes: first, it smooths the inner surface of the sand mold, eliminating grooves and improving the quality of the casting; second, it prevents the cooled metal casting from sticking to the mold cavity or parting surface, which would hinder demolding.

[0003] In the prior art, application number CN202420521248.1 proposes an automatic spraying device for sand molds. In this device, a longitudinal transfer device is mounted on a transverse transfer device, and a spraying device is mounted on the longitudinal transfer device. This allows for both transverse and longitudinal transfer of the spraying device, thereby increasing its spraying range. A spraying cylinder drives the conical block downwards, which in turn drives the nozzle on the abutment block to move radially towards the base plate, thus expanding the nozzle's spraying range. When a small area of ​​spraying is required, the spraying cylinder causes the conical block to retract upwards, causing the abutment block to move axially towards the base plate under the spring force, bringing the nozzles closer together.

[0004] During the use of the aforementioned patent, the nozzle was oriented downwards, which allowed the nozzle to effectively spray the bottom of the sand mold. However, if the side wall of the sand mold had a certain curvature, the top-to-bottom spraying method could not spray the sand mold evenly, resulting in spraying dead corners on the side wall of the sand mold, making it difficult to demold at the four corners. Based on the above problems, this application proposes a sand mold spraying device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-5A sand mold spraying device includes a mounting base 1. The top of the mounting base 1 is equipped with a placement component for easily placing the sand mold. A mounting frame 6 is fixedly mounted on the top of the mounting base 1. A rotating shaft 11 is rotatably mounted inside the mounting frame 6. The rotating shaft 11 has a circular structure and is made of metal, resulting in higher strength and less susceptibility to deformation. A drive component is provided on the surface of the mounting frame 6 to facilitate the rotation of the rotating shaft 11. A discharge pipe 16 is fixedly mounted at the bottom end of the rotating shaft 11. Several inlets 17 are provided through the surface of the discharge pipe 16, and all inlets 17 are connected through the discharge pipe. On the surface of the mounting frame 6, the inlet 17 is a rectangular slot, allowing the paint to enter the outlet pipe 16 through the inlet 17, thus preventing blockage when the paint enters the outlet pipe 16. A paint conveying assembly is provided on the surface of the mounting frame 6. A conveying hose 25 is fixedly installed at the bottom of the outlet pipe 16, and an installation pipe 21 is fixedly installed at the bottom of the conveying hose 25. A nozzle 24 is threadedly installed inside the installation pipe 21. A flipping assembly is provided on the surface of the outlet pipe 16 to facilitate the rotation of the nozzle 24 by driving the installation pipe 21. The driving assembly includes a drive motor 7 fixedly installed on the upper side wall of the mounting frame 6. A drive wheel 8 is fixedly installed at the output end of the drive motor 7, and a meshing mechanism is provided inside the drive wheel 8. A drive belt 9 has a driven pulley 10 meshing inside it. The driven pulley 10 is fixedly mounted on the top of the rotating shaft 11. The tilting assembly includes a fixing frame 18 fixedly mounted on the surface of the discharge pipe 16. A servo motor 19 is fixedly mounted on the right side of the fixing frame 18. A fixing block 20 is fixedly mounted on the output end of the servo motor 19. The fixing block 20 is fixedly mounted on the right side of the mounting pipe 21. A connecting block 22 is fixedly mounted on the left side of the fixing block 20. A fixing shaft 23 is fixedly mounted on the left side of the connecting block 22. The fixing shaft 23 is rotatably mounted inside the fixing frame 18. The servo motor 19 drives the fixing block 20 to move the mounting pipe 21. The flipping action causes the connecting block 22 to rotate the fixed shaft 23 inside the fixed frame 18, which in turn causes the mounting tube 21 to flip the nozzle 24. Subsequently, the drive motor 7 drives the rotating shaft 11 to rotate via the drive wheel 8, the transmission belt 9, and the driven wheel 10, which in turn causes the discharge pipe 16 to rotate the fixed frame 18 and the conveying hose 25. The fixed frame 18 then drives the fixed block 20 and the connecting block 22 to rotate via the servo motor 19 and the fixed shaft 23, which in turn causes the mounting tube 21 to rotate the nozzle 24. This allows for easy adjustment of the spraying angle of the nozzle 24, enabling the nozzle 24 to spray the coating onto different positions of the sand mold, avoiding dead corners in the sand mold spraying, and making it easier to demold the metal casting.

[0023] Specifically, the placement component includes a hydraulic push rod 2 fixedly installed on the top of the mounting base 1. A placement plate 3 is fixedly installed at the output end of the hydraulic push rod 2. A guide post 4 is fixedly installed at the bottom of the placement plate 3. A guide sleeve 5 is slidably installed on the surface of the guide post 4. The guide sleeve 5 is fixedly installed on the top of the mounting base 1. The sand mold is placed on the top of the placement plate 3. The hydraulic push rod 2 drives the output end to push the placement plate 3 upward, so that the placement plate 3 drives the guide post 4 to slide inside the guide sleeve 5. This causes the placement plate 3 to drive the sand mold upward, allowing the nozzle 24 to enter the interior of the sand mold. This facilitates the spraying of the sand mold by the nozzle 24 and allows the position of the nozzle 24 inside the sand mold to be changed, so that the nozzle 24 can spray the sand mold at different heights, making the sand mold sprayed more comprehensively.

[0024] Specifically, the paint delivery assembly includes a delivery pump 12 fixedly installed on the top of the mounting frame 6. A delivery pipe 13 is fixedly installed at the discharge end of the delivery pump 12, and a discharge hood 14 is fixedly installed at the discharge end of the delivery pipe 13. The discharge hood 14 is rotatably mounted on the surface of the discharge pipe 16. The inlet 17 is located inside the discharge hood 14. Limiting plates 15 are attached to both the upper and lower sides of the discharge hood 14. The limiting plates 15 are fixedly installed on the surface of the discharge pipe 16. The delivery pump 12 draws external paint into the delivery pipe 13, and then into the discharge hood 14 through the delivery pipe 13. It then enters the discharge pipe 16 through the inlet 17, and then into the delivery hose 25 through the discharge pipe 16. Finally, it enters the nozzle 24 through the mounting pipe 21, so that the nozzle 24 sprays the paint into the sand mold, thereby facilitating the spraying of the sand mold by the nozzle 24.

[0025] The sand mold spraying device is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0026] In use: The servo motor 19 drives the output end to rotate the fixed block 20, which in turn drives the mounting tube 21 to rotate. This causes the mounting tube 21 to rotate the connecting block 22, which in turn causes the fixed shaft 23 to rotate inside the fixed frame 18. This causes the mounting tube 21 to rotate the nozzle 24, changing the spraying position of the nozzle 24. The drive motor 7 then drives the output end to rotate the drive wheel 8. The drive wheel 8 drives the driven wheel 10 to rotate via the transmission belt 9, which in turn drives the rotating shaft 11 to rotate. This causes the rotating shaft 11 to rotate the discharge pipe 16, which in turn causes the fixed frame 18 and the conveying hose 25 to rotate. The fixed frame 18, through the servo motor 19 and the fixed shaft 23, drives the fixed block 20 and the connecting block 22 to rotate. This causes the fixed block 20 and the connecting block 22 to rotate the mounting tube 21, which in turn drives the nozzle 24 to rotate. This allows the nozzle 24 to spray paint onto different positions of the sand mold.
