[0026] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see the appendix Figure 1 - Appendix Figure 6 This utility model discloses an adjustable pressure ceramic blank pressing device, including a base 1, two hydraulic rods 2 connected to the upper end face of the base 1, the extension and retraction of the two hydraulic rods 2 are connected to a support plate 3, a mold assembly 5 is provided inside the base 1, and a pressing assembly 4 is provided on the lower end face of the support plate 3.

[0028] The mold assembly 5 includes a release plate 51, a heating coil 52, a pull rod 53, a sleeve 54, and a connecting plate 55. The surface of the pull rod 53 is slidably connected to the inner wall of the sleeve 54. The side of the connecting plate 55 is slidably connected to the inside of the base 1. The lower end face of the release plate 51 is connected to the upper end face of the connecting plate 55. The upper end face of the base 1 is connected to the side of the heating coil 52. The side of the release plate 51 is slidably connected to the inner wall of the heating coil 52. The lower end face of the support plate 3 is connected to the top end of the pull rod 53. The bottom end of the sleeve 54 is connected to the upper end face of the connecting plate 55. The upper end face of the mounting plate 42 is connected to the lower end face of the support plate 3. The surface of the sleeve 54 is slidably connected to the inner wall of the base 1.

[0029] The pressing assembly 4 includes a mounting plate 42, magnetic strips 43, a pressing block 44, a slider 45, a cutting blade 46, a connecting shaft 48, and a limiting groove 410. The surface of the connecting shaft 48 is rotatably connected to the inner wall of the mounting plate 42. Multiple magnetic strips 43 are evenly spaced on the inner wall of the mounting plate 42. The limiting groove 410 is opened on the upper end face of the pressing block 44. The surface of the connecting shaft 48 is slidably connected to the inner wall of the limiting groove 410. The side of the slider 45 is slidably connected to the inner wall of the pressing block 44. The side of the slider 45 is connected to the side wall of the cutting blade 46. The magnetic strips 43 and the slider 45 are magnetically connected. The magnetic force of the magnetic strips 43 on the slider 45 is directed away from the center of the mounting plate 42. A second spring 49 is connected to the inner wall of the limiting groove 410. The top end of the second spring 49 is connected to the bottom end of the connecting shaft 48. A first spring 47 is connected to the inner wall of the pressing block 44. One end of the first spring 47 is connected to the side wall of the slider 45.

[0030] In the first embodiment, a servo motor 41 is connected to the upper end face of the support plate 3, and the output end of the servo motor 41 passes through the lower end face of the support plate 3 and is connected to the top end of the connecting shaft 48.

[0031] Specifically, the servo motor 41 is mounted on the upper surface of the support plate 3, and its output end is connected to the top of the connecting shaft 48. By driving the connecting shaft 48 to rotate, it drives the pressing block 44 and other components in the pressing assembly 4 to move, thereby realizing the pressing operation on the ceramic blank.

[0032] In embodiment 2, a third spring 56 is connected to the inner wall of the sleeve 54, and the top end of the third spring 56 is connected to the bottom end of the pull rod 53;

[0033] Specifically, the third spring 56 is connected between the inner wall of the sleeve 54 and the bottom end of the pull rod 53, which plays a role in buffering and resetting, and helps the mold assembly 5 to move smoothly and the parts to reset.

[0034] Working principle:

[0035] First, the ceramic blank raw material is placed on the release plate 51 of the mold assembly 5. The hydraulic rod 2 is activated, and the two hydraulic rods 2 extend and retract synchronously, pushing the support plate 3 to move downward. Since the lower end face of the support plate 3 is connected to the pressing assembly 4, the pressing assembly 4 will descend together with the support plate 3. At this time, the servo motor 41 is activated, and the output end drives the connecting shaft 48 to rotate. While the connecting shaft 48 rotates in the mounting plate 42, its surface slides in the limiting groove 410 on the upper end face of the pressing block 44, thereby driving the pressing block 44 to move downward and apply pressure to the ceramic blank raw material placed on the release plate 51 for pressing.

[0036] As the pressing block 44 moves downward, the magnetic strips 43 connected at equal intervals on the inner wall of the mounting plate 42 will generate a magnetic force on the slider 45 connected to it. The direction of the magnetic force is away from the center of the mounting plate 42. Under the action of the magnetic force, the slider 45 overcomes the elastic force of the first spring 47 connected to the inner wall of the pressing block 44 and slides on the inner wall of the pressing block 44. This drives the cutting blade 46 connected to it to move away from the center of the mounting plate 42. During the movement, the cutting blade 46 will cut off the excess part of the ceramic blank, so that the ceramic blank is formed into the required shape.

[0037] After pressing is completed, the hydraulic rod 2 retracts, driving the support plate 3 and pressing assembly 4 to move upward. At this time, the second spring 49 connected to the inner wall of the limiting groove 410 will push the connecting shaft 48 to reset upward, so that the pressing block 44 returns to the initial position. At the same time, the first spring 47 on the inner wall of the pressing block 44 will pull the slider 45 and the cutting blade 46 back to the initial position. In addition, if the inner wall of the sleeve 54 is connected to the third spring 56, the third spring 56 will play a buffering and assisting reset role during the relative movement of the pull rod 53 and the sleeve 54. When the support plate 3 rises to a certain height, the connecting plate 55 in the mold assembly 5 slides upward inside the base 1, driving the ejector plate 51 to rise, and ejecting the formed ceramic blank from the mold, completing the entire pressing process. Thus, the entire workflow ends.
