The control panel 5 controls the bottom end of the hydraulic cylinder 2 to move vertically downward, thereby compacting the sand box placed between the upper pressing plate 3 and the lower pressing plate 4, and the vertical molding machine base 1 is away from An adjusting chamber 6 is provided on one side of the lower pressing plate 4, and a connecting base frame 7 is fixedly installed on the outside of the adjusting chamber 6. Guide slide rails 8 are symmetrically installed on the opposite surfaces of the inner wall of the connecting base frame 7. A cleaning mechanism is connected between the two guide slide rails 8. After the sand box is compacted, part of the molding sand adheres to the surfaces of the upper pressing plate 3 and the lower pressing plate 4 and falls to the bottom. The cleaning mechanism installed in the adjusting chamber 6 can clean the molding sand adhered to the surfaces of the upper pressing plate 3 and the lower pressing plate 4. The cleaned and fallen molding sand can fall into the interior of the residual material collection box 14 for storage, thereby meeting the cleaning needs of the vertical molding machine.

[0023] The cleaning mechanism includes a carrier frame 9 installed between two guide rails 8, a cleaning component 10 installed inside the carrier frame 9, a motor 11 fixedly installed on the side of the carrier frame 9 close to the connecting base frame 7, and a residual material collection box 14 fixedly installed at the bottom end of the carrier frame 9. The output end of the motor 11 can drive the cleaning component 10 installed inside the carrier frame 9 to rotate at a uniform speed. The scraper 12 on the outer surface of the rotating cleaning component 10 can effectively remove the sand adhering to the upper pressure plate 3 or the lower pressure plate 4, and the sand removed from the surface of the upper pressure plate 3 and the lower pressure plate 4 can be cleaned by using the cleaning brush 13 and transported to the inside of the residual material collection box 14.

[0024] In this embodiment, specifically: the carrier 9 is a C-shaped structure, and both ends of the carrier 9 are connected to the adjacent carriers 9 through connecting blocks. The carrier 9 is adapted to the structural size and position of the guide slide 8. The cleaning assembly 10 is composed of an active roller and a driven roller rotatably mounted inside the carrier 9 and a transmission belt connected between the active roller and the driven roller. A plurality of scrapers 12 are fixedly mounted on the outer surface of the transmission belt. The scrapers 12 are V-shaped. A plurality of scrapers 12 are arranged at equal intervals on the transmission belt. A cleaning brush 13 is fixedly mounted on the outer surface of the transmission belt between two adjacent scrapers 12. The cleaning assembly 10 is tilted inside the carrier 9. The output shaft of the motor 11 passes through the carrier 9 and is connected to the active roller on the cleaning assembly 10. When the vertical molding machine is in use, the carrier 9 will Being inside the adjustment chamber 6 will not affect the operation of the vertical molding machine. When the vertical molding machine needs to be cleaned, the carrier 9 can be pushed along the guide slide 8 so that one end of the residual material collection box 14 is in contact with the outer circumference of the lower pressure plate 4. Then the output end of the motor 11 is used to drive and drive the active roller on the cleaning component 10 inside the carrier 9 to rotate. Under the transmission of the active roller, the transmission belt and the scraper 12 and the cleaning brush 13 on the outer surface of the transmission belt can be driven to move synchronously. The scraper 12 can contact the sand on the surface of the upper pressure plate 3 and the lower pressure plate 4 and effectively scrape it off. At the same time, the cleaning brush 13 can further clean the surfaces of the upper pressure plate 3 and the lower pressure plate 4 of the removed sand, and at the same time, the removed sand is swept into the interior of the residual material collection box 14 for storage.

A screen 15 is fixedly installed inside the discharge port. The screen 15 is adapted to the size and position of the discharge port structure. The longitudinal cross-section of the screen 15 is a conical structure. A discharge port is formed at one end of the residual material collection box 14, and a collection drawer 16 is slidably installed inside the discharge port. The collection drawer 16 is fixed to the residual material collection box 1 4. The structural dimensions and positions are adapted to each other. When the residual material collecting box 14 moves along the guide rail 8 following the carrier 9, it can fit with the outer circumferential surface of the lower pressing plate 4 to reduce the falling of the removed sand. At the same time, the residual material collecting box 14 can limit the moving position of the carrier 9. The removed sand can fall into the interior of the residual material collecting box 14. The sand entering the residual material collecting box 14 can be screened through the screen 15, and the compacted sand can be screened out to facilitate the subsequent crushing process for reuse.

[0026] When the utility model is working: the bottom end of the hydraulic cylinder 2 is controlled by the control panel 5 to move vertically downward, thereby compacting the sand box placed between the upper pressing plate 3 and the lower pressing plate 4. After the sand box is compacted, part of the molding sand adheres and falls onto the surfaces of the upper pressing plate 3 and the lower pressing plate 4. The molding sand adhered to the surfaces of the upper pressing plate 3 and the lower pressing plate 4 can be cleaned by the cleaning mechanism installed in the regulating chamber 6. The cleaned and fallen molding sand can fall into the interior of the residual material collection box 14 for storage, thereby meeting the cleaning needs of the vertical molding machine;

[0027] When the vertical molding machine is in use, the carrier 9 will be inside the adjustment chamber 6 and will not affect the operation of the vertical molding machine. When the vertical molding machine needs to be cleaned, the carrier 9 can be pushed along the guide rail 8 so that one end of the residual material collection box 14 is in contact with the outer circumferential surface of the lower pressing plate 4.

[0028] Then, the output end of the motor 11 is used to drive and drive the active roller on the cleaning component 10 inside the carrier 9 to rotate. Under the drive of the active roller, the transmission belt and the scraper 12 and the cleaning brush 13 on the outer surface of the transmission belt can be driven to move synchronously. The scraper 12 can contact the sand on the surface of the upper pressure plate 3 and the lower pressure plate 4 and effectively scrape it off. At the same time, the cleaning brush 13 can further clean the surfaces of the upper pressure plate 3 and the lower pressure plate 4 of the cleared sand, and at the same time, clean the cleared sand into the interior of the residual material collection box 14 for storage.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
