[0002] Dry pressing forming refers to a common blank forming method in ceramic production. Granulate the powder with a small amount of binder, then load it into a mold, and apply pressure on a press to make the powder particles approach each other in the mold and firmly combine with each other by internal friction to form a blank with a certain shape.

[0003] During the process of pouring ceramic powder into the corresponding mold, in order to ensure the forming quality and reduce cost loss, after the ceramic powder is poured, the scraping action is manually performed to scrape off the excess ceramic powder above the mold. However, this method not only increases the burden on the staff, but also cannot automatically collect, resulting in waste of ceramic powder materials. Therefore, in order to solve this problem, this case is generated, and a dry pressing and powder scraping device for ceramic powder is designed. Content of the Utility Model

One end of the top end of the lower module 1 is provided with a mounting plate 10, and a servo motor 15 is installed on one side of the mounting plate 10. The output end of the servo motor 15 penetrates through one side of the mounting plate 10 and is connected to a threaded rod 19, and a threaded block 20 is sleeved on the outer side of the threaded rod 19. One end of the mounting plate 10 is provided with a scraper 17. A top plate 12 is installed at the top end of the bottom plate 5, and a movable plate 11 is arranged below the top plate 12. An upper module 14 is installed at the bottom end of the movable plate 11, and second electric telescopic rods 13 are installed around the top end of the movable plate 11 through bolts. The top ends of the second electric telescopic rods 13 are connected to the bottom end of the top plate 12 through bolts;

[0021] The scraper 17 is in a C shape, and the length of the scraper 17 is the same as the length of the top end of the lower module 1. The bottom end of the scraper 17 and the top end of the lower module 1 are on the same horizontal plane;

[0022] Both ends of the threaded block 20 are in contact with both ends inside the mounting plate 10, and one end of the threaded block 20 is in contact with one end of the scraper 17 through welding;

[0023] The upper module 14 is arranged directly above the lower module 1, and the height of the upper module 14 is greater than the height of the mounting plate 10. The length of the mounting plate 10 is greater than the length of the top end of the lower module 1, and the length of the collection block 9 is the same as the width of the lower module 1;

[0024] Specifically, as Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, during the use of this device, first, due to the presence of the lower module 1 and the forming cavity 16 in this device, the corresponding ceramic powder can be poured into the interior of the forming cavity 16. Then, due to the presence of the second electric telescopic rod 13 in this device, under the telescopic action of the second electric telescopic rod 13, the movable plate 11 can be driven to move up and down as a whole, thereby realizing the downward movement process of the upper module 14. By utilizing the downward movement of the upper module 14, the dry pressing and forming effect of the ceramic powder inside the forming cavity 16 can be achieved. During this process, in order to improve the dry pressing and forming quality, accurately control the quantity, and reduce cost losses, due to the presence of the collecting block 9 and the mounting plate 10 in this device, before the upper module 14 moves downward for dry pressing and forming, due to the presence of the servo motor 15 in this device, by utilizing the drive of the servo motor 15, the threaded rod 19 rotates. Due to the rotation of the threaded rod 19 and the restriction of the inner wall of the mounting plate 10, the threaded block 20 can be made to move horizontally. During the horizontal movement of the threaded block 20, the scraping plate 17 can be driven to move horizontally. In this way, the scraping plate 17 can scrape above the lower module 1, scraping off the excess ceramic powder above the lower module 1, and under the push of the scraping plate 17, the excess ceramic powder can be pushed into the interior of the collecting block 9 for collection. In this way, the dry pressing and forming quality of this device can be effectively increased, cost damage can be reduced, and it is relatively convenient.

[0025] Embodiment 2: A connecting plate 18 is arranged inside the fixed ring plate 2, and a connecting rod 4 is hinged to the bottom end of the connecting plate 18 through a hinge. A top block 3 is arranged inside the forming cavity 16, and a vertical rod 8 is installed at the bottom end of the top block 3. The bottom end of the vertical rod 8 penetrates the bottom end inside the forming cavity 16 and extends into the fixed ring plate 2, and one end of the vertical rod 8 inside the fixed ring plate 2 is connected to the top end of the connecting plate 18 by welding. Two first top telescopic rods 6 are installed at the top end of the bottom plate 5 inside the fixed ring plate 2, and one end of the first top telescopic rod 6 is bolted to a movable block 7;

[0027] The outer side of the top block 3 is in contact with the inner wall of the forming cavity 16, and the bottom end of the top block 3 is in contact with the bottom end inside the first top telescopic rod 6;

[0028] Specifically, as Figure 1 and Figure 2As shown, in order to improve the convenience of the device, after the device performs dry pressing on the ceramic powder, with the presence of the top block 3, the telescopic movement of the first top telescopic rod 6 drives the movable block 7 to move horizontally. During the horizontal movement of the movable block 7, through the connection relationship of the two connecting rods 4, the connecting plate 18 can move up and down stably. In this way, during the upward movement of the connecting plate 18, the vertical rod 8 and the top block 3 are driven to move, so that the top block 3 can eject the dry-pressed ceramic powder embryo in the forming cavity 16, enabling the staff to take it out, realizing the process of convenient material taking of the device and increasing the working efficiency of the device.
