[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] 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.

[0025] Please see Figures 1-3A precision aluminum casting sandblasting and polishing device includes a sandblasting box with a pair of operating ports 3 on the front. Operating gloves 4 are installed inside the operating ports 3, allowing the user to reach into the sandblasting box for operation. A transparent cover 5 is rotatably mounted on the upper surface of the sandblasting box. When closed, it seals the top opening of the sandblasting box, facilitating observation of the internal operation. When opened, it allows for easy placement or removal of the precision aluminum casting being processed. A filter screen 6 is also installed on the outer wall of the sandblasting box to maintain airflow and pressure stability inside and outside the box, while filtering the air to prevent abrasive from escaping. A sand box 7 is installed on the back of the sandblasting box for storing abrasive. The sand box 7 is connected to the sand pipe 9 via the sand pump 8. The sand pipe 9 extends into the sand blasting box and is connected to the nozzle 12. The sand pump 8 draws the abrasive into the nozzle 12 through the sand pipe 9 and sprays it out. An air pipe 10 also extends through the back of the sand blasting box. One end of the air pipe 10 extends out of the box and is open to the air. The other end of the air pipe 10 extends into the box and is connected to the tail end of the nozzle 12 via the air pump 11, thereby compressing the air into the nozzle 12 to drive the abrasive to be sprayed out at high speed. A partition net 13 is also installed in the sand blasting box to facilitate the placement of precision aluminum castings and to facilitate the abrasive to fall down, preventing the abrasive from accumulating on the surface of the partition net 13. Accumulated abrasive is easily blown up during sand blasting, forming dust pollution.

[0026] Please see Figures 3-4 To facilitate the assembly of the sandblasting box, the sandblasting box is made up of a lower box 1 and an upper box 2 connected by several bolts, and the partition 13 is pressed between the edges of the lower box 1 and the upper box 2, so that the sandblasting box can be opened from the top and bottom for easy internal cleaning.

[0027] Furthermore, a funnel-shaped guide shroud 14, wider at the top and narrower at the bottom, is connected to the lower part of the mesh 13. A collection box 15 is provided under the guide shroud 14, and the collection box 15 is slidably connected to the sandblasting box. The guide shroud 14 can concentrate and guide the falling abrasive into the collection box 15, and the collection box 15 is relatively easy to remove from the sandblasting box.

[0028] Please see Figures 1-2 To improve the stability of the transparent cover 5 when it is closed, a pressure block 23 is rotatably installed on the front edge of the sandblasting box via a rotating rod 22. The bottom end of the rotating rod 22 is fixed to the sandblasting box, and the pressure block 23 rotates and fits onto the top end of the rotating rod 22. The pressure block 23 presses the upper edge of the transparent cover 5 to limit the position of the transparent cover 5. When the pressure block 23 rotates and moves away from the transparent cover 5, the locking of the transparent cover 5 can be released.

[0029] Please see Figure 3 and Figure 5Considering that the abrasive sticks to the inner surface of the transparent cover 5 during sandblasting, which may affect the user's ability to observe the inside of the sandblasting box, a cleaning rod 16 is movably installed on the inner top surface of the sandblasting box to ensure that the user can always clearly observe the inside of the box. The cleaning rod 16 is parallel to the width direction of the transparent cover 5 and slides along the length direction of the transparent cover 5. A cleaning cotton strip 17 is connected to the side of the cleaning rod 16 facing the transparent cover 5, and the cleaning cotton strip 17 is in contact with the transparent cover 5, so that when the cleaning rod 16 slides, it can drive the cleaning cotton strip 17 to wipe the surface of the transparent cover 5.

[0030] Furthermore, considering that the cleaning tampons 17 may wear out during use and that their cleaning force may be intertwined after becoming contaminated, the cleaning tampons 17 and the cleaning rod 16 are connected by Velcro, which facilitates the replacement of the cleaning tampons 17 later.

[0031] Please see Figure 5 To facilitate automatic cleaning control of the cleaning rod 16, movable blocks 18 are symmetrically installed at both ends of the cleaning rod 16. A screw 19 is threaded through and connected to one of the movable blocks 18. Both ends of the screw 19 are connected to the sandblasting box through bearing seats, and one end of the screw 19 passes through the bearing seat and is connected to a motor 20, thereby driving the screw 19 to rotate through the motor 20. A guide rod 21 is slidably connected through the other movable block 18. Both ends of the guide rod 21 are fixed to the sandblasting box through mounting plates. The guide rod 21 is used to prevent the cleaning rod 16 from tilting or shifting when moving.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
