The outer surface of the threaded rod 506 is threadedly rotatably connected to an internal thread block 505. The bottom of the internal thread block 505 is fixedly connected to a moving block 503. The outer surface of the threaded rod 506 is fixedly connected to a position near the rear surface of the internal thread block 505. A limiting block 507 The limit block 507 is matched with the internal thread block 505, and the pressurizing assembly 6 includes a connecting plate 601, which is fixedly connected to the bottom of the moving block 503, and the bottom of the connecting plate 601 is symmetrically fixedly connected with a connecting rod 604, and the bottoms of the two connecting rods 604 are fixedly connected with a placement plate 608, and the center of the bottom of the connecting plate 601 is fixedly connected with a first hydraulic rod 602, and the telescopic end of the first hydraulic rod 602 is fixedly connected with a cover 603, and the cover 603 is matched with the cylinder body 4, and the inner The surface is symmetrically fixedly connected with a sliding sleeve 606, the inner surfaces of the two sliding sleeves 606 are slidably connected to the outer surfaces of the two connecting rods 604, the top of the base 1 near the four corners is fixedly connected with a fixed sleeve 2, the inner surfaces of the multiple fixed sleeves 2 are respectively slidably connected with fixed sliding rods 3, the tops of the multiple fixed sliding rods 3 are fixedly connected to the bottom of the mounting frame 501, the inner surfaces of the mounting frame 501 are symmetrically fixedly connected with fixed rods 504, and the outer surfaces of the two fixed rods 504 are slidably connected to the inner surface of the moving block 503.

[0025] The effect achieved by the entire embodiment 1 is that when the ZTA wear-resistant ceramic isostatic pressing molding device is used, the initial position of the placement plate 608 is at the top of the base 1, located on the front side of the cylinder body 4. After the staff places the mold containing the ZTA wear-resistant ceramic powder blank on the top of its placement plate 608, the two second hydraulic rods 7 are started synchronously, and the telescopic ends of the two second hydraulic rods 7 extend upward, driving the mounting frame 501 to move upward, and the mounting frame 501 slides in the corresponding fixed sleeve 2 through a plurality of connected fixed slide bars 3, which plays a role in limiting the position. When the mounting bracket 501 is moved up to a suitable height, the placement plate 608 is higher than the top of the cylinder body 4, and the motor 502 is started. The output end of the motor 502 drives the threaded rod 506 to rotate clockwise in the inner wall of the mounting bracket 501, and the internal thread block 505 drives the moving block 503 to move backward on the outer surface of the two fixed rods 504 until the internal thread block 505 stops after contacting the limit block 507.

[0028] Working principle: When the ZTA wear-resistant ceramic isostatic pressing device is used, the initial position of the placement plate 608 is at the top of the base 1, located on the front side of the cylinder body 4. After the staff places the mold containing the ZTA wear-resistant ceramic powder blank on the top of its placement plate 608, the two second hydraulic rods 7 are started synchronously. The telescopic ends of the two second hydraulic rods 7 extend upward, driving the mounting frame 501 to move up. The mounting frame 501 slides in the corresponding fixed sleeve 2 through a plurality of connected fixed slide bars 3, which plays a limiting role. When the mounting frame 501 moves up to a suitable height, the placement plate 608 is higher than the top of the cylinder body 4, and the motor 502 is started. The output end of 2 drives the threaded rod 506 to rotate clockwise in the inner wall of the mounting frame 501, and the internal thread block 505 drives the moving block 503 to move backward on the outer surface of the two fixed rods 504 until the internal thread block 505 stops after hitting the limit block 507.

At this time, the bottom of the pressurizing component 6 is suspended on the top of the cylinder body 4, and the placement plate 608 is aligned with the center of the cylinder body 4. The two second hydraulic rods 7 are started synchronously again to reset their two telescopic ends and move downward. The overall synchronous downward movement of the mounting frame 501 will drive the pressurizing component 6 to move into the cylinder body 4, and the placement plate 608 and the mold placed on the top of it will go deep into the cylinder body 4 The liquid in the cylinder 4 will immerse the mold, and then the first hydraulic rod 602 will be started, and its telescopic end will extend outward to push the cover 603, and the cover 603 will slide down on the outer surfaces of the two connecting rods 604 through the two sliding sleeves 606. During the continuous downward movement of the cover 603, the liquid inside the cylinder 4 will be pressurized. Due to the incompressible nature of liquids and other media, the rubber material mold in the liquid will be subjected to the pressure transmitted in all directions by the liquid, which acts on the ZTA wear-resistant ceramic powder blank inside it, so that the internal molecules are tightly combined. After waiting for a long time under the continuous static pressure, the production of the ZTA wear-resistant ceramic blank is completed, and the mold The removal of the tool only requires the reverse operation. The entire removal process does not require the assistance of personnel, intervention and guidance, which reduces the workload of the staff. By setting a first sealing ring 605 on the outer surface of the cover 603, the cover 603 can seal the cylinder body 4 when it moves down in the cylinder body 4. The second sealing ring 607 set at the bottom of the two sliding sleeves 606 seals the connection between the cover 603 and the connecting rod 604. The circular groove 609 set at the center of the top of the placement plate 608 can quickly position the mold, making it easier to place it at the center of the placement plate 608, thereby improving the use effect of the ZTA wear-resistant ceramic isostatic pressing molding device.
