Description
Technical field
The utility model is related to a kind of manufacture device of high density ceramic target raw embryo, and in particular to a kind of high density ceramic
Target raw embryo shaped device, belongs to field of mechanical technique.
Background technology
As global electronic information industry is fast-developing, the use of thin-film material is more and more frequent, and the performance of target is to thin
The production of membrane material is most important.And ceramic target is mainly used in electronics and information industry, such as integrated circuit, information Store,
LCDs, laser memory, electronic control device etc.；It is equally applicable for coating film on glass field；Can also be applied to wear-resisting
The industries such as material, high temperature are anti-corrosion, high-grade adornment.The mainly powder metallurgic method of manufacturing of conventional ceramic target includes powder
Last compacting sintering method, Powder hot isostatic pressure method etc..The ceramic target of all kinds can be almost produced with such method, and
Can reach target density higher, however such method not only the production cycle is long, complex procedures but also production cost is high.In recent years
Come such as AZO, TiO2All produced using the high-temperature sintering process of relative ease Deng ceramic target production, the difficulty of its maximum is to use stone
The raw embryo that cream slip casting produces certain density is controlled sintering atmosphere and is sintered again.Raw embryo production process be mainly by
Ceramic powder is made into the mud with mobility, is then injected into porous mold (predominantly plaster mold), and moisture is inhaled by gypsum
Just formd after entering with certain thickness uniform mud layer, form the base substrate with some strength during dehydrating simultaneously,
But manufactured with such method and had the following disadvantages：
(1) cannot precise control grouting amount.
(2) gypsum injection forming idiosome water content is up to 50%-70%, is easily deformed when burning till.
(3) gypsum injection forming green density is small, shrinks big, it is not easy to control shape.
(4) production cycle is long, generally requires several days or even longer.
(5) mould loss is big.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of manufacture device of high density ceramic target raw embryo,
Compared to common gypsum injection forming, the device is easy to operate, and shaping speed is fast, and can produce high density ceramic target raw embryo.
The technical solution of the utility model is as follows：
A kind of manufacture device of high density ceramic target raw embryo, including mold, lower mould, pellicle filter cloth and vacuum are taken out
Filter, the mold is nested in the lower mould, and the pellicle filter cloth is arranged at the mold and the lower mould
Between, the mold bottom is provided with grid, and the lower mold bottom is provided with a connector, and the vacuum filtration machine includes
Bottle,suction and vavuum pump, the bottle,suction arrival end are connected by the connector with the lower mould, the bottle,suction outlet
End connects with the vavuum pump.
Wherein, the mold and the lower mould interference fit.
Wherein, the mold sets fluid sealant with the nested junction of the lower mould.
Wherein, mold side wall is provided with scale.
Wherein, the grid mesh number is 200 mesh.
Wherein, a diameter of 6mm of the connector.
Wherein, the filtration grade of the pellicle filter cloth is nano-scale.
Compared to existing technology, the utility model has following advantage：
1st, contrast gypsum injection forming idiosome utility model production process whole course visible, easy to operate, the utility model
Exception can be avoided the occurrence of so as to calculate idiosome moisture accounting by the actual precise control idiosome thickness of mold scale.
2nd, by the utility model be molded idiosome aqueous proportion can drop to 10%-15%, well below gypsum slip casting into
The aqueous proportion 50-70% of type idiosome.
3rd, realization pressurization is persistently evacuated by vavuum pump, thus idiosome is more densely cross-linked uniform, can produce high density ceramic
Target raw embryo, than gypsum injection forming green density 10-20% high.
4th, shaping speed is fast, and whole process only needs to 30min, and the production time greatly shortens.
5th, mold and lower die cost are low, can be recycled for multiple times, and consumable accessory only has pellicle filter cloth, if any damage only
Pellicle filter cloth need to be re-replaced.
6th, the demoulding is easy, solves contact surface and idiosome other positions moisture accounting difference.
