Description

Technical Field

[0001] This utility model relates to the field of isostatic graphite production technology, and in particular to a vertical forming device for cylindrical isostatic graphite. Background Technology

[0002] To form isostatic graphite products, the raw material needs to be loaded into a mold (such as a rubber mold), and then the mold is placed in the sealed container of an isostatic press. The isostatic press uses liquid to gradually increase pressure in the sealed container, and the raw material is compressed and formed through liquid pressure transmission.

[0003] Due to the limited volume of sealed containers, in order to improve the production efficiency of small isostatic graphite products, the molds can be stacked horizontally in the isostatic press. However, for large cylindrical isostatic graphite products, the weight of the molds and raw materials can easily lead to mutual compression and deformation, which requires improvement. Utility Model Content

[0004] The purpose of this invention is to provide a cylindrical isostatic graphite vertical forming device for vertical forming, which avoids the problem of mutual compression and deformation, and improves production efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0010] The first cap has a first annular plug located between the outer and inner rubber sleeves. The first annular plug has a first screw that extends upward through the first cap. The first screw has a third nut located above the first cap. The outer circumference of the first annular plug has a first conical surface pointing upward.

[0011] Wherein, the distance between the outer circle at the bottom of the first conical surface and the inner wall of the first cap is less than the wall thickness of the outer rubber sleeve, and the distance between the outer circle at the top of the first conical surface and the inner wall of the first cap is greater than the wall thickness of the outer rubber sleeve.

[0012] The second cap has a second annular plug located between the outer and inner rubber sleeves. The second annular plug has a second screw that extends downward through the second cap. The second screw has a fourth nut located below the second cap. The outer circumference of the second annular plug has a downward-pointing second conical surface.

[0013] Wherein, the distance between the outer circle of the top of the second conical surface and the inner wall of the second cap is less than the wall thickness of the outer rubber sleeve, and the distance between the outer circle of the bottom of the second conical surface and the inner wall of the second cap is greater than the wall thickness of the outer rubber sleeve.

The support tube 3 has radially extending through holes arranged in an array. After the support tube 3 is placed in the sealed container of the isostatic press, liquid enters the support tube 3 and applies pressure to the inner wall of the inner sleeve 2 through the through holes. The outer wall of the outer sleeve 1 comes into contact with the liquid on the outside and is thus pressurized, achieving compression molding of the raw material between the outer sleeve 1 and the inner sleeve 2.

[0025] The second cap 16 is provided with a second annular plug 10 located between the outer rubber sleeve 1 and the inner rubber sleeve 2. The second annular plug 10 is provided with a second screw 14 that penetrates downward through the second cap. The second screw 14 is provided with a fourth nut 15 located below the second cap 16, which facilitates assembly.
