Abstract
The present invention provides a kind of injection forming method of porous ceramic structure, it first provides not yet molding ceramic material, and ceramic material is made to foam for the first time in being kneaded program, then make second in being kneaded program again to foam, and it foams compared to first time, second of foaming is in the environment of at higher temperature, high pressure, finally, ceramic material to be made to required shape with ejection formation again.
Description
Technical field
The present invention is related with a kind of forming method of ceramic manufactured articles, espespecially a kind of to make the zero of porous ceramic structure
The injection forming method of part, component etc..
Background technique
Currently, cellular structure (stores oily) effect in addition to can be applied on such as bearing, axle center part, to provide oil-containing
Outside, since its porosity can increase the touch opportunity with air, therefore good action and effect can be also played in terms of heat dissipation.This
Outside, it similar to bearing, the function in axle center, can also apply on the filtering element (cartridge) of the filter of such as water dispenser, pass through its porous characteristic
The effect of drainage is provided.
Cellular structure is made using ceramic material and has become technology common now.However, in the past porous to make
The ceramic material of property structure when the more careful porous structure in aperture to be made, is often depending on raw material itself, that is, have material
On limitation.But if raw material can be made to may conform to demand and raw material after completing by consistent manufacturing process
When limitation is also unlikely to become main consideration condition, then it can be greatly decreased in technique, many costs on material, and meet into
Product demand.
Summary of the invention
In view of this, the main purpose of the present invention is to provide a kind of injection forming method of porous ceramic structure, energy
It saves cost and porous ceramic structure is made to meet the demand and standard of finished product.
In order to achieve the above object, the present invention provides a kind of injection forming method of porous ceramic structure, step packet
It includes：
A, not yet molding ceramic material is provided；
B, the ceramic material is made to foam for the first time in being kneaded program；
C, again the ceramic material is made to foam for second in being kneaded program, and temperature, the pressure of second of foaming are equal
It is higher than temperature, the pressure of first time foaming；
D, the ceramic material is made with ejection formation by required shape.
It as can be seen from the above technical solutions, will pottery in the mixing program that the present invention passes through the forming process in ceramic material
Ceramic material is foamed twice, makes ceramic material during homogenizing by foaming twice, its can be enabled particles contained more
It is tiny, to meet the demand and standard of finished product, while being greatly decreased in technique, the manufacturing cost on material.

Specific embodiment
In order to enable those skilled in the art to be further understood that feature and technology contents of the invention, please referring to following has
Detailed description and accompanying drawings of the present invention for pass, however appended attached drawing is only for reference and description, and is not used to be subject to the present invention
Limitation.
The present invention provides a kind of injection forming method of porous ceramic structure, can be applied to production using ceramics as material
Radiator 1 (as shown in Figure 2), water dispenser filtering element (cartridge) 2 (as shown in Figure 3), have radiating requirements Lamp cup 3 (as shown in Figure 4) or
It is other to have on the component of cellular structure.
Referring to Fig. 1, the step flow chart of the injection forming method for porous ceramic structure of the present invention.It walks as shown in figure 1
Shown in rapid S1：Firstly, first step is stock, that is, prepare not yet molding ceramic material；Material can be single or compound oxygen
The ceramic material of compound, carbide or nitride, such as zirconium oxide, aluminium oxide, silicon carbide, calcium oxide, magnesia ceramic material.
It holds, as shown in the step S2 of Fig. 1：Ceramic material is put into homogeneous blender to be sufficiently mixed, it is equal to carry out
Matter is kneaded program, meanwhile, enable ceramic material that such as dry type foaming agent (AC) foamed material is added in being kneaded program, to make first
Secondary foaming, the temperature provided at this time are approximately less than 100 DEG C.
Then, as shown in the step S3 of Fig. 1：The aforementioned ceramic material for making foaming for the first time in being kneaded program is carried out again
Second of foaming, and foaming agent used is AC；And compared to foaming of aforementioned first time program, second of foaming is in more
In the environment of high temperature, high pressure, with enable homogenize and pseudo plastic ceramic material containing particle to be formed by particle more tiny, and can
Form about 10%~80% hole ratio.
Finally, as shown in the step S4 of Fig. 1：The injection forming method or skill of the ceramic materials such as such as Jet forming machine can be passed through
Foregoing ceramic material is made required shape, and completes finished product by programs such as de- porcelain, sintering by art.
Therefore, by above-mentioned contexture, the injection forming method of porous ceramic structure of the present invention can be obtained.
As the above analysis, by the injection forming method of porous ceramic structure of the present invention, consistent system can be passed through
Process is made, makes ceramic material in forming process, i.e., is foamed twice in being kneaded program, makes ceramic material taking in raw material
It is more unrestricted on certainly, that is, it may conform to product demand, the manufacturing cost to be greatly decreased in technique, on material.
The foregoing is merely preferable possible embodiments of the invention, and the scope of the patents of the invention is not limited to this, therefore only
To change with equivalence techniques, the means etc. carried out by description of the invention and accompanying drawing content, similarly be all contained in model of the invention
In enclosing.
Finally, it should be noted that above embodiments be only to illustrate the technical solution of the embodiment of the present invention rather than to its into
Row limitation, although the embodiment of the present invention is described in detail referring to preferred embodiment, those skilled in the art
It should be understood that the technical solution of the embodiment of the present invention can be still modified or replaced equivalently, and these are modified or wait
The range of modified technical solution disengaging technical solution of the embodiment of the present invention cannot also be made with replacement.
