Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary ceramic die production equipment, in particular to a ceramic coating die green body forming die. Background Art

[0002] With the continuous application of metal coating dies in the market, the shortcomings of metal dies have also emerged, such as easy deformation, poor impermeability, easy detachment of surface coating, and difficulty in maintenance. In order to improve and innovate the above problems, new material ceramic coating dies have gradually emerged. Among them, the ceramic coating die green body is the first and most critical step in the production of ceramic die finished products. If the green body cannot be formed, the subsequent process cannot continue to be processed. For the green body forming of the ceramic die, the powder needs to be placed in the specific mold body of the green body forming mold. It is formed only after isostatic pressing in the green body forming mold. The structure of the mold body directly affects the effect after forming.

[0003] Existing green body forming molds usually apply pressure along the axial direction of the mold body for forming, and this forming method is generally suitable for processing some small ceramic green bodies. When the length of the ceramic green body is long, the forming effect is poor, so it cannot meet the requirements of long ceramic green body forming. Utility Model Content

[0048] Specifically, the extension portion 9 is made of silicone material, and the extension portion 9 and the silicone sleeve 3 are integrally formed.

[0049] Based on the above implementation, in a preferred implementation, Figure 1 As shown, the sealing assembly 5 further includes a silicone sealing cover 503 , and the silicone sealing cover 503 is located between the sealing cover 501 and the extension portion 9 .

[0055] In this embodiment, the first groove 10 is nested with the extension portion 9 to improve the sealing effect.

[0056] Based on the above implementation, in a preferred implementation, Figure 1 As shown, a second groove 11 is provided on the side of the extension portion 9 facing away from the silicone sleeve 3 , and the sealing cover 501 is adapted to be embedded in the second groove 11 .

[0057] In this embodiment, the second groove 11 is provided to be nested with the sealing cover 501 to improve the sealing effect.

[0058] Based on the above implementation, in a preferred implementation, Figure 1 As shown, a plurality of first through holes 2 are evenly distributed on the mold body 1 .

[0059] In this embodiment, the first through holes 2 are evenly distributed on the mold body 1, which further improves the uniformity of the internal structure of the ceramic coating die green body after molding, and improves the molding efficiency of the ceramic coating die green body.

[0060] Specifically, Figure 1 As shown, the mold body 1 is arranged in a square cylindrical shape, and the silicone sleeve 3 is arranged in a square cylindrical shape to match the molding cavity, and its specific size can be selected according to actual conditions.

[0061] On the basis of the above-mentioned embodiment, in a preferred embodiment, the mold body 1 and the sealing plate 4 are both made of stainless steel.

[0062] In this embodiment, the mold body 1 and the sealing plate 4 are made of stainless steel, which is not easy to deform and rust, and improves the bearing capacity.

[0063] Specifically, the mold body 1 and the sealing plate 4 are connected by welding to improve the connection strength.

[0064] Specifically, the fixing plates 8 are made of stainless steel and are connected to the mold body 1 by welding to improve the connection strength.

[0065] The installation and specific working principle of the ceramic coating die blank molding mold provided in this embodiment are as follows: when it is necessary to make a ceramic coating die blank, first, the silicone sleeve 3 is adapted and embedded into the molding cavity through the open end of the mold body 1 until the extension part 9 is embedded in the first groove 10 of the fixed plate 8, and then the ceramic powder is filled into the inner cavity of the silicone sleeve 3 through the open end of the silicone sleeve 3. After filling, the silicone sealing cover 503 is clamped between the extension part 9 and the sealing cover 501 through the sealing cover 501, and the sealing cover 501 is connected to the fixed plate 8 through the screw 502, thereby sealing the open end of the silicone sleeve 3, and then the whole is placed in an isostatic pressing device and the mold body 1 is fixed by bolts passing through the connecting hole 7 on the sealing plate 4. The fluid in the isostatic pressing device applies static pressure to the ceramic powder in the silicone sleeve 3 through the first through hole 2 and the second through hole 6 on the mold body 1, thereby completing the molding of the ceramic coating die blank. The ceramic coating die head green body molding mold provided in this embodiment withstands liquid pressure in all directions through the mold body 1, is not easy to deform, and adopts a silicone sleeve 3, which is convenient for fitting into the molding cavity and is not easy to penetrate water, so as to achieve a dense effect during pressing, and is convenient for withstanding the pressure at different stages inside the isostatic pressing equipment through the silicone sleeve 3. In addition, the silicone sleeve 3 is limited at both ends of the mold body 1 by the sealing plate 4 and the sealing component 5 to avoid separation from the molding cavity during the static pressure process, thereby improving stability and the molding effect, and static pressure molding is applied to the peripheral side of the mold body 1 through the first through hole 2. For the molding method in which static pressure is applied along the axial direction of the mold body 1, which makes it difficult for the static pressure to act on the middle position of the mold body 1, the static pressure can be uniformly applied to the ceramic powder in the silicone sleeve 3 along the length direction of the mold body 1, ensuring that the static pressure can act on every part of the ceramic powder in the silicone sleeve 3, making it easier to mold the ceramic coating die blank, improving the uniformity of the internal structure of the ceramic coating die blank after molding, and achieving a better molding effect. At the same time, the molding efficiency is improved, making it easier to realize the mass production of ceramic coating die blanks, and it can be applied to the molding of ceramic coating die blanks of different lengths. The technical problem that the existing blank molding mold is generally suitable for processing some small ceramic blanks and cannot meet the molding requirements of longer ceramic blanks is solved.

[0066] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
