Abstract
The utility model relates to an isostatic molding device for preparing high-purity graphite. The isostatic molding device comprises a high-pressure cylinder and a rubber mould, wherein an upper piston and a lower piston are arranged on the high-pressure cylinder; steel wire layers are arranged in the high-pressure cylinder through an upper flange and a lower flange; an ultrahigh-pressure cavity is formed by the steel wire layers in a surrounding way; and the rubber mould is arranged in the ultrahigh-pressure cavity through a support frame and provided with an injection hole. Due to the arrangement of the steel wire layers, when a liquid medium is injected into the ultrahigh-pressure cavity through a pressure pump, the pressure of the ultrahigh-pressure cavity is kept unchanged and uniformly transmitted to all directions according to the principles of fluid mechanics, and the pressure applied to the graphite powder in all directions is uniform and consistent, thus the final graphite product is molded compactly with no defects of cold shrinkage and air holes, and the service life of the graphite product is prolonged.
Description
Technical field
The utility model relates to a kind of shaped device, is specifically related to a kind of high purity graphite preparation isostatic compaction device, belongs to the graphite material production technical field.
Background technology
Graphite has high temperature resistant, good electrical and thermal conductivity, stable chemical performance, so it is very extensive in industrial utilization.Industrial use be mostly synthetic graphite, special graphite namely can be divided into isostatic pressing formed graphite, die-pressed graphite, extruded anisotropic graphite by the mode of its moulding.The isostatic pressing method that wherein adopts in the isostatic pressing formed graphite production process is to utilize liquid or gaseous media in high pressure vessel that the elastic mould that aleuron is housed is evenly pressurizeed from all directions, thickener is subjected to molded.The graphite-structure that this method is produced is even, and density is high.
Be used for specially at present the isostatic compaction device of graphite moulding, because of the problem of stopping property, the pressure that makes the graphite powder be subject in all directions when moulding is not of uniform size to be caused, thereby the defective of shrinkage and pore occurs, and the graphite of making is shorter work-ing life.
The utility model content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of high purity graphite preparation and uses isostatic compaction device, can extend the work-ing life of the graphite of preparation.
The technical solution of the utility model: a kind of high purity graphite preparation isostatic compaction device, comprise high-pressure cylinders, rubber model, described high-pressure cylinders is provided with upper piston, lower piston, be provided with steel wire floor by upper flange, lower flange in high-pressure cylinders, steel wire floor surrounds a ultra-high voltage chamber, rubber model is arranged in the ultra-high voltage chamber by bracing frame, and rubber model is provided with sprue.
The beneficial effects of the utility model are: owing to being provided with steel wire floor, when liquid medium injects the ultra-high voltage chamber by pressure pump, according to fluid mechanics principle, constant and the Transmit evenly of its pressure size is to all directions, the pressure that the graphite powder is subject on all directions is uniform, consistent, make the graphite products moulding that finally prepares fine and close, avoid occurring the defective of shrinkage and pore, thereby extended the work-ing life of graphite product.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Now reach with the following Examples accompanying drawing, utility model is described in detail.
In Fig. 1, a kind of high purity graphite preparation isostatic compaction device, comprise high-pressure cylinders 1, rubber model 2, high-pressure cylinders 1 is provided with upper piston 1.1, lower piston 1.2, be provided with steel wire floor 3 by upper flange 3.1, lower flange 3.2 in high-pressure cylinders 1, steel wire floor 3 surrounds a ultra-high voltage chamber 4, and rubber model 2 is arranged in ultra-high voltage chamber 4 by bracing frame, and rubber model 2 is provided with sprue.
Graphite raw material is packed in rubber model 2, the ultra-high voltage chamber 4 of static pressure such as then rubber model 2 is put into, and control upper and lower piston 1.1,1.2 to the height that is suitable for the moulding graphite product. carry out precharge, the liquid of pre-pressure pump output directly enters in ultra-high voltage chamber 4, pressure in high-pressure cylinders 1 increases gradually, liquid medium applies uniform pressure for equably rubber model 2 to all directions, and after the graphite powder is subject to uniform pressure, final molding becomes graphite product closely.
