Description
Technical field
The utility model relates to isostatic pressing formed graphite isostatic pressing equipment, and in particular to a kind of isostatic pressing formed graphite rubber sleeve.
Background technique
Due to isostatic pressing formed graphite using etc. by the way of static pressure, generally using hydraulic oil or water as pressure transfer device,
In equal static pressure die mould production process, need press-powder to be attached to inside dedicated rubber sleeve.It is customized according to the shape of production product
The shape of rubber sleeve, general rubber sleeve are cylindrical body or cuboid.Cylindrical body isostatic pressing formed graphite use is mainly used in light
Volt field；Cuboid isostatic pressing formed graphite is mainly used in the fields such as EDM electric discharge, continuous casting, sintering.Cylindrical body isostatic pressing formed graphite with
The increase of monocrystal thermal-field, outer diameter constantly increase.But it waits in iso-press process, due to being cylindrical body die sleeve, pressure is from outside inward
Apply, is lower than outside so as to cause the material index in all respects at center, the index for even resulting in the material at center occurs not
Qualified phenomenon.
Utility model content
The utility model is intended to solve the problems, such as performance indicator difference inside and outside isostatic pressing formed graphite and product is caused defect occur.
The solution of the utility model is:
A kind of isostatic pressing formed graphite rubber sleeve, including upper Membrane cover, lower Membrane cover, the lower Membrane cover are the cylindrical body of inner hollow,
Opening arranged at the top of the lower Membrane cover, and the edge of the upper Membrane cover opening is provided with inward flange, at the center of the lower Membrane cover
It is vertically arranged with a lower Membrane cover rubber tube；The upper Membrane cover is hollow cylinder identical with lower Membrane cover diameter, the upper film
Opening is arranged at the lower part of set, is provided with outward flange, the center on the upper Membrane cover top on the outside of the edge of the opening of the lower Membrane cover
Place is provided with Membrane cover rubber tube.
Further, the top of the lower Membrane cover rubber tube is provided with ring buckle, and the ring buckle is enclosed in the lower film
It covers outside rubber tube, has sealed groove on the inside of the ring buckle, the corresponding position of the upper Membrane cover rubber sleeve is provided with sealing
Flange, the sealed groove are bonded to each other with the sealing flange.
Further, the sealed groove and the sealing flange are T-shaped.
Further, a vacuum air valve is provided on the upper Membrane cover.
The utility model has the following beneficial effects: by making isostatic pressure of the equal static pressure green compact by inside and outside both direction, from
And improve uniformity inside and outside isostatic pressing formed graphite；Article production simultaneously is simple, and cost is relatively low.

Specific embodiment
More detailed description is done to the embodiments of the present invention below in conjunction with attached drawing and appended drawing reference, makes to be familiar with ability
The technology people in domain can implement accordingly after studying this specification carefully.It should be appreciated that specific embodiment described herein is only to solve
The utility model is released, is not used to limit the utility model.
Referring to Fig. 1 to Fig. 3, a kind of isostatic pressing formed graphite rubber sleeve, it is characterised in that: described including upper Membrane cover 1, lower Membrane cover 2
Lower Membrane cover 2 is the cylindrical body of inner hollow, and opening, the edge setting of lower 2 opening of Membrane cover are arranged at the top of the lower Membrane cover 2
There is inward flange 6, a lower Membrane cover rubber tube 4 is vertically arranged at the center of the lower Membrane cover 2；The upper Membrane cover 1 is and lower film
The equal hollow cylinder of 2 diameters is covered, opening, the edge outside of the opening of the lower Membrane cover are arranged at the lower part of the upper Membrane cover 1
It is provided with outward flange 5, is vertically arranged with Membrane cover rubber tube 3 at the center on upper 1 top of Membrane cover.
When it is implemented, being packed full with equal static pressure press-powder in the cavity of the lower Membrane cover 2, upper Membrane cover 2 is covered in lower Membrane cover
Opening, so that inward flange 6 fits with outward flange 5, while lower Membrane cover rubber tube 4 passes through inside upper Membrane cover rubber tube 3, due to
Rubber product has ductility and retractility, and the ring buckle on the lower Membrane cover rubber tube 4 may extend to outside Membrane cover rubber tube 3
Portion states upper 3 outside of Membrane cover rubber tube so that ring buckle 7 is enclosed in, the sealing flange of 7 inside of ring buckle is arranged in by being bonded
With the sealed groove being arranged on upper 3 corresponding position of Membrane cover rubber tube, Membrane cover rubber tube 3 and lower Membrane cover rubber tube are gone up to realize
4 connection；Upper Membrane cover rubber tube 3 and the internal residual gas of the junction of lower Membrane cover rubber tube 4 are extracted out by vacuum air valve,
Prevent remaining air from having an impact in isostatic pressing to center material.
At this time when carrying out equal static pressure operation, the hydraulic fluid of static pressure is waited to pass through lower Membrane cover rubber tube and external two sides
