Description

Technical Field

[0001] This utility model relates to the technical field of sandblasting equipment, specifically to a sandblasting device for making rotatable foam molds. Background Technology

[0002] Foam molds are molds made of foam materials and are the main components in lost foam casting and sand casting production. After production, the surface of foam molds needs to be cleaned to prevent debris from adhering and affecting subsequent casting production. Sandblasting is the most common cleaning method.

[0003] Sandblasting involves using high-speed abrasive particles to impact the surface of an object, thereby cleaning away debris. However, current sandblasting systems have limited internal component movement, especially since the molds are essentially fixed in a specific position. This necessitates frequent adjustments to the mold's angle and orientation to achieve a thorough cleaning, thus extending processing time. Therefore, this paper proposes a sandblasting device for making rotatable foam molds. Utility Model Content

[0004] The technical problem this invention aims to solve is that the internal components of current sandblasting systems have limited range of motion, especially the mold, which is basically fixed in a designated position. This necessitates frequent adjustments to the mold's angle and orientation to achieve a comprehensive cleaning effect, thus extending processing time. This invention provides a rotatable foam mold making sandblasting device that allows the sandblasting nozzle to move in a circular motion, ensuring the sandblasting coverage area. This enables comprehensive sandblasting cleaning of the mold without adjusting the mold itself, thereby improving processing efficiency.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a sandblasting device for making rotatable foam molds, including a processing box, an inner cavity is opened inside the processing box, a mesh plate is inlaid and connected to the bottom side wall of the inner cavity, a guide rail is fixedly connected to the middle of the top side wall of the mesh plate, a vertical column is rotatably connected to the top of the inner cavity, the vertical column is a hollow structure and a horizontal plate is inserted and fixedly connected to its bottom end, a horizontal pipe is connected to one end of the vertical column extending into the horizontal plate through a tee, a toothed ring is fixedly connected to the outer wall of the top of the vertical column, and a gear is meshed with one side of the toothed ring.

[0006] As a preferred technical solution of this utility model, a conveying pipe is fixedly connected to the middle of the two side walls of the horizontal plate. The conveying pipe is a telescopic flexible hose structure. The two ends of the conveying pipe are detachably connected to the horizontal pipe. Telescopic rods are detachably connected to the bottom of the horizontal plate and near the two edge ends.

[0008] As a preferred embodiment of this utility model, a connecting column is fixedly connected to the middle of the top side wall of the gear, and a motor is detachably connected to the top side wall of the processing box. The output end of the motor passes through the top side wall of the processing box and is detachably connected to the top of the connecting column.

[0009] As a preferred technical solution of this utility model, a material box is fixedly connected to the top side wall of the processing box, and a pump is detachably connected to the top of the processing box and the side wall near the material box. The output end of the pump is detachably connected to the top of the vertical column through a pipe.

[0010] As a preferred embodiment of this utility model, two sliders are slidably connected on the guide rail. Each slider has a side plate fixedly connected to its top side wall. Each side plate has a rotating disk rotatably connected to its opposite side wall. One side of the rotating disk has an anti-slip pad fixedly attached.

[0011] This utility model has the following advantages: The starting motor drives the gear to rotate, and through the meshing relationship, the gear and the vertical column rotate. This, in turn, drives the spray head to rotate in a circle through the horizontal plate. During this process, the spray head can spray sand onto the surface of the mold. At the same time, the telescopic rod is activated to drive the spray head to move up and down, thereby achieving comprehensive cleaning without moving the mold. Furthermore, the inner spray head can be rotated and adjusted to achieve the effect of sandblasting and cleaning dead corners, thereby improving the effectiveness of cleaning. Moreover, because it does not require frequent flipping and adjustment, the processing efficiency is improved. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 This utility model discloses a sandblasting device for making rotatable foam molds, including a processing box 1. The processing box 1 has an inner cavity 7. A mesh plate 8 is inlaid and connected to the bottom side wall of the inner cavity 7. A guide rail 9 is fixedly connected to the middle of the top side wall of the mesh plate 8. A vertical column 15 is rotatably connected to the top of the inner cavity 7. The vertical column 15 has a hollow structure and a horizontal plate 14 is inserted and fixedly connected to its bottom end. One end of the vertical column 15 extending into the horizontal plate 14 is connected to a horizontal pipe 19 through a tee. A toothed ring 16 is fixedly connected to the outer wall of the top of the vertical column 15. A gear 17 is meshed and connected to one side of the toothed ring 16. A material box 2 is fixedly connected to the top side wall of the processing box 1. A pump 3 is detachably connected to the top of the processing box 1 and the side wall near the material box 2. The output end of the pump 3 is detachably connected to the top of the vertical column 15 through a pipe.

[0018] A conveying pipe 23 is fixedly connected to the middle of the two side walls of the horizontal plate 14. The conveying pipe 23 is a telescopic hose structure. The two ends of the conveying pipe 23 are detachably connected to the horizontal pipe 19. A telescopic rod 20 is detachably connected to the bottom of the horizontal plate 14 and near the two edge ends. A connecting seat 21 is detachably connected to the output end of the telescopic rod 20. The connecting seat 21 is a U-shaped structure. A spray head 22 is rotatably connected inside the connecting seat 21. A driver 12 is detachably connected to one side of the outer wall of the connecting seat 21. The output end of the driver 12 is detachably connected to one side of the spray head 22. One end of the conveying pipe 23 is detachably connected to one side wall of the spray head 22. A connecting post 18 is fixedly connected to the middle of the top side wall of the gear 17. A motor 4 is detachably connected to the top side wall of the processing box 1. The output end of the motor 4 passes through the top side wall of the processing box 1 and is detachably connected to the top of the connecting post 18.

[0019] The technical effects of this solution are as follows: During processing, the mold is placed stably, and then the motor 4 is started to drive the horizontal plate 14 and the spray head 22 to rotate in a circular motion, so that the sand is sprayed evenly and comprehensively on the surface of the mold, ensuring the comprehensiveness of the sandblasting treatment and improving the cleaning effect. Because the spray head 22 can rotate and adjust its orientation angle, it can effectively clean the dead corners of the mold. The telescopic rod 20 can drive the spray head 22 to rise and fall. Together with the rotating horizontal plate 14, it can avoid any omissions in the sandblasting treatment. The vertical column 15, horizontal pipe 19 and conveying pipe 23 can ensure the smooth conveying of sand and will not affect the rotation and lifting.

[0020] Two sliders 10 are slidably connected to the guide rail 9. Side plates 11 are fixedly connected to the top side walls of the sliders 10. Rotary disks 13 are rotatably connected to the opposite side walls of the side plates 11. An anti-slip pad is fixed to one side of the rotating disk 13. A driver 12 is detachably connected to the outer wall of one of the side plates 11. The output end of the driver 12 passes through the side plate 11 and is detachably connected to the corresponding rotating disk 13. A base plate 5 is fixedly connected to the bottom of the processing box 1 near the two side edges. The base plate 5 has an L-shaped structure and a collection box 6 is inserted into the base plate 5.

[0021] The technical effect of this solution is as follows: the mold is placed between two side plates 11, and the two side plates 11 are driven to move closer to each other. The mold is clamped and positioned by two rotating disks 13 to ensure the stability of the mold. A lifting component can be installed inside the side plates 11, so that the driver 12 can be activated to drive the rotating disks 13 to rotate, thereby adjusting the horizontal state of the mold and cleaning the ends. During the processing, the side plates 11 can be moved to one end, so that the rotating disks 13 will block the mold, and the moved side plates 11 will not affect the normal rotation of the horizontal plate 14.

[0022] A mesh plate 8 is connected to the bottom of the inner cavity 7, which can send the sand that falls after spraying into the collection box 6. This reduces the amount of sand that accumulates in the inner cavity 7, reduces the frequency of cleaning, increases the frequency of processing, and makes it easier to collect and clean the sand in the collection box 6 for reuse.

[0023] Specifically, when using this utility model, the mold to be processed is placed between two side plates 11, and then the side plates 11 are moved by the slider 10. Finally, the mold is clamped by the rotating disk 13 to make the mold in the center position, ensuring that the impact force of the two spray heads 22 on the mold is the same, thereby ensuring the uniformity of cleaning and avoiding the impact force from affecting the cleaning effect. After the mold is positioned, the pump 3 is started to send the sand in the material box 2 into the spray head 22 through the pipe for sandblasting. If necessary, the side plates 11 can be moved to the end of the guide rail 9, which can avoid the rotating disk 13 from blocking the mold and affecting the overall treatment effect (the guide rail 9 and slider 10 refer to the principle of cylinder guide rail).

[0024] The side plate 11 can be replaced with a lifting assembly, which can work with the driver 12 to adjust the horizontal angle of the mold and achieve the effect of cleaning the mold end;

[0025] The sand generated during cleaning will pass through the mesh plate 8 and fall into the collection box 6 for unified collection and storage, making it convenient for cleaning and reuse.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0027] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
