Abstract
The utility model discloses an Al2O3-ceramic-ring cold press forming device. The Al2O3-ceramic-ring cold press forming device comprises a mold core rod, a mold cylinder jacket, a sliding core column and a mold base, wherein the mold base is sleeved with the mold cylinder jacket and provided with a base groove matched with the sliding core column, the sliding core column is arranged in the base groove of the mold base, the mold core rod is provided with a core rod groove matched with the sliding core column, the mold core rod is arranged in the mold cylinder jacket, the sliding core column is sleeved with the core rod groove of the mold core rod, and a cavity for containing Al2O3 ceramic powder is formed between the mold core rod and the mold base. The Al2O3-ceramic-ring cold press forming device effectively solves problems in the prior art, is simple in structure and low in cost, and can enable Al2O3 ceramic ring not to adhere to the mold base; meanwhile the forming ratio is high, and follow-up processing is not needed after sintering.
Description
Technical field
The utility model relates to field of material synthesis technology, is specifically related to a kind of Al
2o
3ceramic ring cold moudling device.
Background technology
Synthetic with in ceramic raw material at common superhard material, normally injection forming, plastic molding, compressing, injection forming blank water content is 30～40%, and plastic molding blank water content is 18～26%, and compressing blank water content is 6～8%.First two molding mode operational sequence is many, production efficiency is low, owing to noting, part water content is high, and density is little, shrinks large, while burning till, noting part is easily out of shape, the loss of mould is large, after forming and sintering, still needs a series of following process operations such as cutting, peripheral milling, inner circle mill, and the compressing mode of the latter, note part water content low, density is large, shrinks little, during sintering, note part distortion little, after sintering, do not need following process operation, but compressing mode should not make blank moulding, after compacting, blank can be bonded in above mold base, and unsuitable mould unloading is removed.
Utility model content
By Given this, the purpose of this utility model is to provide a kind of Al

3the non-caked mold base of ceramic ring does not need again following process after the high sintering of ratio of briquetting simultaneously.
To achieve these goals, the utility model is by the following technical solutions:
A kind of Al
2o
3ceramic ring cold moudling device, wherein, comprise die mandrel, mould cylinder sleeve, slip stem stem and mold base, described mould cylinder is set on mold base, and mold base is provided with the base groove matching with the stem stem that slides, and slip stem stem is located in the base groove of mold base, described die mandrel is provided with the plug groove matching with the stem stem that slides, die mandrel is located in mould cylinder sleeve, and its plug groove and slide cores column sleeve close, and have placement Al between die mandrel and mold base
2o
3the cavity of ceramic powder.
As preferably, the base groove of described mold base is through hole.
The beneficial effects of the utility model are:
The utility model is simple in structure, with low cost, easy to use, and employing hollow mould base and in midair mould stem stem, can make Al
2o
3the non-caked mold base of ceramic ring does not need again following process after the high sintering of ratio of briquetting simultaneously.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating below, or can from practice of the present utility model, be instructed.Target of the present utility model and other advantages can be by below description or accompanying drawing in specifically noted structure realize and obtain.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises die mandrel 1, mould cylinder sleeve 2, mold base 4 and slip stem stem 5, mould cylinder sleeve 2 is located on mold base 4, mold base 4 is hollow structure, mold base 4 is provided with the base groove matching with the stem stem 5 that slides, the base groove of mold base 4 is through hole, and slip stem stem 5 inserts in the base groove of mold base 4.Die mandrel 1 is half hollow structure, and die mandrel 1 is provided with the plug groove matching with the stem stem 5 that slides, and die mandrel 1 is located in mould cylinder 2 covers, its plug groove and slip stem stem 5 fits, and 4 of die mandrel 1 and mold bases have placement Al
2o
3the cavity of ceramic powder, Al
2o
3ceramic powder 4 is put into cavity.
Workflow of the present utility model is:
First slip stem stem 5 is inserted on mold base 4, then mould cylinder sleeve 2 is placed on the mold base 4 that is inserted with slip stem stem 5, by Al
2o
3ceramic powder 3 is put into mould cylinder sleeve 2, by stirring rod, will put into the Al of mould cylinder sleeve 2 the insides
2o
3ceramic powder 3 stirs, and die mandrel 1 is placed on to mould cylinder sleeve 2 the insides, and a whole set of mould is put into above cold press and suppressed, pressurize 10～15s first takes off mold base 4, then mould unloading from whole die device, whole ceramic ring just, on slip stem stem, only need be taken off gently.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of claim scope of the present utility model.
