[0015] Furthermore, a rubber sheet is arranged on the upper surface of the support rod.

[0016] Beneficial effects

[0017] First paragraph: When the staff needs to perform isostatic pressing forming on the ceramic green body, the staff needs to place the ceramic green body in the bottom basin and connect the pressing plate with the bottom basin, so that the ceramic green body can be kept stable. Subsequently, in order to perform isostatic pressing forming on a plurality of ceramic green bodies at one time, the staff needs to dock a plurality of bottom basins. At this time, the staff needs to connect the support grooves on another annular plate with the support rods and press the upper bottom basin, so that the limiting component can be automatically opened and limit the support rods, thereby keeping the two bottom basins stable, and further reducing the difficulty of the staff in docking the bottom basins;

[0018] Second paragraph: When the staff connects the support rod with the support groove on another annular plate, the staff only needs to press down the annular plate, so that the support rod abuts against the inclined surface, and then the arc plate completely moves into the first arc groove under the action of the support rod. Subsequently, when the first arc groove is aligned with the limit hole, the arc plate is connected with the limit hole under the action of the limit spring, so that the arc plate can block the support rod, thus keeping the support rod stable.

Detailed Description of the Embodiments

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] The present utility model will be further described below in conjunction with embodiments.

[0028] In some embodiments, please refer to the accompanying Figures 1-4 , an isostatic pressing forming device for a circular ceramic part, including a bottom basin 1, a pressing plate 11, an annular plate 2, a support rod 21, a limiting component 4, an arc rod 5, a push rod 6, an annular block 61, a moving disk 7, a moving ring 8, and a rubber sheet 9. The pressing plate 11 is arranged in the bottom basin 1 and is used to keep the ceramic green body stable. The annular plate 2 is a plate-like structure with a circular cross-section, and the annular plate 2 is arranged on the upper surface of the bottom basin 1. The support rod 21 is a rectangular rod-like structure, and a plurality of support rods 21 are provided and fixed on the upper surface of the annular plate 2.

[0029] A plurality of support grooves 3 corresponding to the support rods 21 one by one are opened on the bottom surface of the annular plate 2. A first arc groove 31 is opened on the inner wall of the support groove 3. The limiting component 4 is arranged on the annular plate 2 and is used to limit the support rod 21. The limiting component 4 includes an arc plate 41 and a limiting spring 42. The arc plate 41 is a plate-like structure with a circular cross-section. The arc plate 41 is slidably arranged in the first arc groove 31, and an inclined surface is opened on the bottom surface of the arc plate 41 and on the side wall away from the limiting spring 42. One end of the limiting spring 42 is fixed on the side wall of the arc plate 41 away from the support rod 21, and the other end of the limiting spring 42 is fixed on the inner wall of the first arc groove 31. A limiting hole 43 matching the arc plate 41 is opened at the upper end of the side wall of the support rod 21.

[0030] When the staff connects the support rod 21 with the support groove 3 on another annular plate 2, the staff only needs to press down the annular plate 2, then the support rod 21 can be made to press against the inclined surface, and further the arc plate 41 can be completely moved into the first arc groove 31 under the action of the support rod 21. Subsequently, when the first arc groove 31 is aligned with the limiting hole 43, the arc plate 41 is connected with the limiting hole 43 under the action of the limiting spring 42, so that the arc plate 41 can block the support rod 21, thereby keeping the support rod 21 stable.

[0031] The arc rod 5 is a round rod-like structure with an arc-shaped trajectory. One end of the arc rod 5 is fixed on the side wall of the arc plate 41 away from the support rod 21. The other end of the arc rod 5 is slidably connected with the inner wall of the first arc groove 31, and the arc rod 5 is arranged in the limiting spring 42.

[0032] The arc rod 5 improves the stability of the limiting spring 42, thereby reducing the probability of the arc plate 41 getting stuck, and thus improving the use experience of the staff.

[0033] A second arc-shaped groove 51 is formed through the inner top wall of the first arc-shaped groove 31. The push rod 6 is in a rod shape and is fixed to the arc-shaped plate 41. The annular blocks 61 are in a block shape with a circular-arc cross-section and are jointly mounted on a plurality of push rods 6.

[0034] When the staff needs to take out the green ceramic body, the staff needs to separate two adjacent bottom basins 1 from each other. At this time, the staff needs to rotate the annular block 61, so that a plurality of push rods 6 can move simultaneously under the action of the annular block 61, and then a plurality of arc-shaped plates 41 can rotate simultaneously, and then a plurality of arc-shaped plates 41 can be separated from the support rods 21 simultaneously. Further, the staff only needs to pull up the upper bottom basin 1 to separate the two bottom basins 1 from each other, thereby reducing the difficulty for the staff to take out the green ceramic body.

[0035] The moving plate 7 is mounted on the upper surfaces of a plurality of support rods 21. The moving ring 8 is in a circular ring shape and is arranged on the upper surface of the moving plate 7 to reduce the difficulty for the staff to move the bottom basin 1.

[0036] In order to reduce the difficulty for the staff to install the support rod 21, a rubber sheet 9 is arranged on the upper surface of the support rod 21.

[0037] The working principle of an isostatic pressing forming device for circular ceramic parts in this embodiment is as follows: when the staff needs to perform isostatic pressing on the green ceramic body, the staff needs to place the green ceramic body in the bottom basin 1 and connect the pressing plate 11 with the bottom basin 1, so that the green ceramic body can be kept stable. Subsequently, in order to perform isostatic pressing on a plurality of green ceramic bodies at one time, the staff needs to dock a plurality of bottom basins 1. At this time, the staff needs to connect the support grooves 3 on another annular plate 2 with the support rods 21 and press the upper bottom basin 1, so that the limiting component 4 can be automatically opened to limit the support rods 21, thereby keeping the two bottom basins 1 stable and further reducing the difficulty for the staff to dock the bottom basins 1.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
