Description
Technical field
The utility model belongs to special cermacis production equipment field, and in particular to a kind of isostatic tooling.
Background technology
Special cermacis, also known as fine ceramics are classified by its application function, can substantially be divided into high intensity, high temperature resistant and compound
Two major class of structural ceramics and electrotechnical, electronic function ceramics.The inorganic material being especially formulated is added in ceramic batch, by 1360
The molding of left and right high temperature sintering is spent, so as to obtain reliable and stable antistatic performance, becomes a kind of new special ceramics, usually has
One or more functions, such as：The functions such as electricity, magnetic, light, heat, sound, chemistry, biology；And coupling function, such as piezoelectricity, thermoelectricity, electricity
The functions such as light, acousto-optic, magneto-optic；
There are many kinds of special cermacis manufacturing process, should select manufacturing process, such as thousand pressures in production according to the shape of product
Method, casting, extrusion, injection and isostatic pressing method；Wherein, isostatic pressing is that sample to be pressed is placed in high pressure-volume
In device, sample is carried out uniformly to add from all directions using the incompressible property of liquid medium and the property for uniformly transferring pressure
Pressure, when liquid medium injects pressure vessel by compression pump, according to fluid mechanics principle, pressure size is constant and equably
All directions are transmitted to, the pressure that the powder in high-pressure bottle is subject in all directions at this time is uniform and in the same size
's；However, in isostatic pressing pressing process, the product that product design size is big, wall thickness is thick is frequently encountered, must be adopted thus
With Special rubber sleeve and cover board, this need to specially issue mold, and easily be gone out due to shaped article wall thickness thickness using common rubber cover board
The uneven phenomenon such as existing end face inclined-plane, increases later stage Vehicle Processing surplus.
Utility model content
The purpose of this utility model be to provide a kind of structure novel, practical function isostatic tooling.
Technical solution provided by the utility model is：A kind of isostatic tooling, including mold core and rubber sleeve, the mold core
The center of the rubber sleeve is co-axially located at, the upper end of the rubber sleeve is provided with metal cover board, in the rubber sleeve
Lower end is provided with lower metal cover board；Sealing ring is additionally provided between metal cover board and the mold core on described, under described
Lower seal is additionally provided between metal cover board and the mold core；The upper sealing ring and lower seal use U-shaped sealing ring.
As a kind of improvement of the utility model, the upper metal cover board and lower metal cover board are stainless steel cover board, aluminium
Alloy cover board or iron covering plate.
As a kind of improvement of the utility model, the outer surface of the mold core is provided with chrome layer.
As a kind of improvement of the utility model, control type outer layer is additionally provided in the outside of the rubber sleeve, in the control
Deflector hole is also evenly arranged on type outer layer.
As a kind of improvement of the utility model, the control type outer layer is rigid metal outer layer or high-intensity resin layer.
As a kind of improvement of the utility model, the deflector hole is circular hole, and aperture is 6 millimeters to 20 millimeters.
Advantageous effect：
The utility model structure novel, practical function are coordinated by the activity of metal cover board plus U-shaped sealing ring, instead of passing
The Special rubber sleeve and rubber cover board of the special die sinking customization of system, improve the rigidity of cover board, ensure that the smooth of product end surface, into
And so that product quality is more excellent, meanwhile, also save the special expense that molds, flexible multi-purpose, economical and efficient；
Chrome layer is set on mold core outer surface, pollution of the mold core to ceramic powder can be effectively reduced, but also molding mass
Part demoulding is more convenient；Setting control type outer layer can effectively control molding accuracy, and General Purpose Rubber is avoided to cover, and matter is soft to be deformed upon
And then cause to be molded the problem of deviateing, better ensure the concentricity of product inside and outside circle；
The round deflector hole in 6 millimeters to 20 millimeters of aperture is uniformly arranged on control type outer layer, isostatic pressed can be efficiently accomplished
Molding technology requirement, ensure that one-pass molding and the dimensional accuracy of product.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
1 it is mold core in figure, 11 is chrome layer, 2 is upper metal cover board, and 3 be upper sealing ring, 4 is rubber sleeve, 41 is control type
