[0025] Please refer to Figures 1-4, A rapid sand cleaning device for a casting sand box, including a base 1. A vertical plate 2 is welded to the top surface of the base 1, and a top plate 3 is fixedly connected to the top end of the vertical plate 2. The surface of the vertical plate 2 is rotatably connected to a sand box 7 through a rotating column 6. A second gear 8 is fixedly connected to the surface of the rotating column 6. A locking component 9 is fixedly connected to the inner wall of the vertical plate 2 at a position corresponding to the second gear 8. A reduction motor 4 is fixedly installed on the outer wall of the vertical plate 2, and the output end of the reduction motor 4 is equipped with a first gear 5, and the first gear 5 meshes with the second gear 8. A collecting plate 11 is arranged below the inner wall of the vertical plate 2, and a collecting box 12 is arranged below the collecting plate 11. A support 13 is arranged at the rear side of the sand box 7 on the inner wall of the vertical plate 2, and a guide rod 14 penetrates through the surface of the support 13. One end of the guide rod 14 is fixedly connected to a vibration block 15, and a return spring 16 is sleeved on the outer side of the guide rod 14 between the vibration block 15 and the support 13. The other end of the guide rod 14 is equipped with a limit block 17, and a pulley 18 is installed on the surface of the limit block 17 away from the guide rod 14. A driving motor 19 is installed on the inner wall of the vertical plate 2, and the output end of the driving motor 19 is equipped with a cam 20, and the cam 20 is used in cooperation with the pulley 18.

[0026] When in use, by setting the flip - able sand box 7, the reduction motor 4 drives the first gear 5 to rotate. The rotation of the first gear 5 drives the second gear 8 to rotate, thereby driving the sand box 7 to flip 180° through the rotating column 6. At this time, the driving motor 19 drives the cam 20 to rotate, which can intermittently push the vibration block 15 to strike the sand box 7. The vibration of the sand box 7 facilitates the vibration and shedding of the molding sand inside, achieving the effect of rapid sand cleaning, with strong practicability and worthy of promotion. At the same time, the bidirectional lead screw module 92 drives the two locking blocks 93 to approach each other and clamp the second gear 8, achieving the effect of locking the second gear 8, so that the sand box 7 is fixed, avoiding the shaking of the sand box 7 during the casting process and improving the stability during use.

[0027] In this implementation scheme: The locking component 9 includes a locking frame 91, a bidirectional lead screw module 92, a locking block 93, and a locking plate 94. The bidirectional lead screw module 92 is fixedly installed on the top surface of the locking frame 91, and the locking block 93 is installed on the bidirectional lead screw module 92. A locking plate 94 is arranged on the surface of the locking block 93 close to the locking plate 94, and the locking plate 94 is used in cooperation with the second gear 8.

[0028] Specifically, the bidirectional lead screw module 92 drives the two locking blocks 93 to move away from each other and release the second gear 8, achieving the effect of releasing the second gear 8, so that the sand box 7 can be flipped to facilitate the rapid cleaning of the molding sand in the sand box 7.

[0029] In this implementation scheme: A control panel 10 is installed on the vertical plate 2, and the control panel 10 is electrically connected to the reduction motor 4 and the driving motor 19 through wires.

[0030] Specifically, it is a common circuit connection structure, which will not be elaborated here. Similarly, the bidirectional lead screw module 92 can also be electrically connected to the control panel 10 through wires to achieve its control.

[0031] In this implementation: The length of the locking block 93 is less than the radius of the second gear 8.

[0032] Specifically, it is ensured that the locking block 93 does not affect the rotation of the second gear 8.

[0033] In this implementation: A discharge port is provided at the position of the aggregate plate 11 corresponding to the aggregate box 12.

[0034] Specifically, it can collect the molding sand cleaned down.

[0035] In this implementation: The vibration block 15 abuts against the outer wall of the sand box 7.

[0036] Specifically, it can vibrate the sand box 7 to facilitate rapid cleaning.

[0037] In this implementation: The controller is of an existing structure, and the control circuit can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in this field. Only its use is described without modification, so the control method and circuit connection will not be described in detail.

[0038] Working principle: During use, by setting the reversible sand box 7, the reduction motor 4 drives the first gear 5 to rotate. The rotation of the first gear 5 drives the second gear 8 to rotate, so as to drive the sand box 7 to flip 180° through the rotating column 6. At this time, the driving motor 19 drives the cam 20 to rotate, which can intermittently push the vibration block 15 to strike the sand box 7. The vibration of the sand box 7 facilitates the vibration and shedding of the internal molding sand, achieving the effect of rapid sand cleaning, with strong practicability and worthy of promotion. At the same time, the bidirectional lead screw module 92 drives the two locking blocks 93 to approach each other and clamp and fix the second gear 8, achieving the effect of locking the second gear 8, so that the sand box 7 is fixed, avoiding the shaking of the sand box 7 during the casting process and improving the stability during use.

[0039] It should be noted that: The model specifications of the reduction motor 4 and the driving motor 19 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.
