Abstract
It the utility model is related to a kind of cold isostatic compaction mould of the tubular ceramic material more strict to outside dimension requirement, mould for earthenware cold isostatic compaction includes metal die, rubber mold and sealing structure, the rubber mold is tubular die, and in the inside of metal die, powder is filled in the space between metal inner surface and rubber mold outer wall, then seals and is suppressed again.The ceramic pipe outer wall smooth even of this mould compacting, accurate size, it is suitable for the earthenware shaping higher to external diameter requirement.
Description
Technical field
The forming technique of ceramic material is the utility model is related to, for the cold isostatic compaction of ceramic material, is further related to
A kind of and cold isostatic compaction for requiring outside dimension higher earthenware.
Background technology
Cold isostatic compaction is placed into the rubber mold for filling powder in closed container, by oil pump apply it is each to
Equal pressure, in the presence of high pressure, the moulding process of fine and close base substrate is made.For earthenware, usually put at center
Put a metal bar core, rubber mold covers outside, filled between rubber mold and metal bar core powder and sealing just entered it is cold
It is compressing in isostatic pressing machine, then rod core and rubber mold are taken out, rod core segment constitutes the inner chamber of earthenware.
It is to core portion when being pressurized along with ceramic powder because rod core is that metal material can be processed accurately
It is close to, institute's obtained earthenware in this way, the higher internal diameter size of precision can be obtained；But because the outer wall of earthenware is
Formed by rubber mold to the compression of core rod direction, inwall, powder uniformity, powder by rubber sleeve send the parameters such as dress density
Influence, so the earthenware that often this traditional method is worked it out, its external diameter is not smooth enough, plucked, while outer diameter ruler
It is very little also to change greatly, for the earthenware that external diameter requires more strict, it is necessary to be machined, both wasted before sintering
Raw material increases production difficulty and cost again.
Utility model content
In order to solve the problems, such as that outside dimension cannot be guaranteed after the shaping of conventional tube earthenware cold isostatic mould, this practicality
New technical scheme is as follows：
A kind of mould for earthenware cold isostatic compaction, including metal pattern, rubber pattern and sealing device, metal pattern exist
Outside, including rubber pattern, the powder filled space between metal pattern inwall and rubber pattern outer wall.
Described earthenware cold isostatic compaction mould, metal pattern and rubber pattern are tubulose.
One end of described earthenware cold isostatic compaction mould, metal pattern and rubber pattern is blind end.
One end of described earthenware cold isostatic compaction mould, metal pattern and rubber pattern is blind end.
Described earthenware cold isostatic compaction mould, Metal mould material are stainless steel or carbon steel.
Described earthenware cold isostatic compaction mould, the inwall chromium plating of metal die.
Described earthenware cold isostatic compaction mould, rubber mold material be neoprene, silicon rubber, polyvinyl chloride and
Paracyanogen ester one kind therein.
After mould is put into the hydraulic medium of cold isostatic press, hydraulic medium enters the center of rubber mold, by powder
Compressed to the inwall of metal die, so the earthenware external diameter suppressed is smooth and has good precision.
The utility model is used for the mould of earthenware cold isostatic compaction as a result of the metal opposite with traditional moulds
Mould and rubber pattern, metal pattern are allowed to limit the external diameter of earthenware, it is possible to good outside dimension and precision are obtained, for outer
Footpath requires that higher earthenware can be molded with dead size and need not be reprocessed, and had not only improved efficiency but also had saved material.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model both ends open ceramics pipe shaping mould.
Fig. 2 is the structural representation that ceramic pipe shaping mould is closed in the utility model one end.
Embodiment
It is described in detail with reference to the accompanying drawings and examples to of the present utility model.
Embodiment 1
It is the structural representation of the utility model both ends open ceramics pipe shaping mould as shown in Figure 1, this mould includes gold
Category mould 100, rubber touch 101 and seal member 103.Outside, rubber touches 101 inside to said metal mould 100, and powder 102 is filled
Between metal pattern 100 and rubber pattern 101, then mould is sealed with seal member 103 up and down, by charged and the mould of good seal
Tool is put into cold isostatic press inner chamber 105 and pressurizeed, and hydraulic medium 104 equably gives powder pressing from the inner side of rubber mold 102,
Because metal die 100 is that intensity is high, deformation is not pressurised, so the external diameter of earthenware base substrate is close to metal die after compacting
100 inwall, its size uniform are accurate.
Embodiment 2
It is illustrated in figure 2 the structural representation that ceramic pipe shaping mould is closed in the utility model one end.
This embodiment is similar with embodiment 1, and simply earthenware one end is with top pressure closure, so metal die
100 and rubber mold 101 be one end closing, only one end has seal member 103 to seal.
It the foregoing is only preferable embodiment of the present utility model, it is impossible to therefore and be interpreted as to the utility model patent
The limitation of protection domain, all equivalent changes and modifications done according to the utility model claims scope, should all belong to this reality
With the covering scope of new claim.
Claims (6)
1. a kind of mould for earthenware cold isostatic compaction, including metal pattern, rubber pattern and sealing device, its feature exist
