Abstract
A ceramic tile isostatic pressing die comprises a steel base body, an oil cavity, an elastic body, a group of mutually communicated step-shaped oil cavities or a large plane groove-shaped oil cavity with a sealing groove arranged at the periphery is distributed on the working surface of the steel base body at equal distance, the elastic body is glued on the steel base body at the periphery of the oil cavity, and the distance between the bottom surface of the elastic body and the surface of the step ring is smaller than the depth of the oil cavity or the distance between the bottom surface of the elastic body and the bottom surface of the large plane groove-shaped oil. The utility model has the advantages of be difficult to appear gluing and take off or the tympanic bulla phenomenon, elastomer long service life obtains the isostatic pressing area big, and the isostatic pressing effect is showing, still can use and realize two-way isostatic pressing on the die down.
Description
The utility model relates to the tile mould technical field, particularly a kind of ceramic tile isostatic tooling.
The monoblock type isostatic tooling that existing a kind of ceramic tile is used, its structure is referring to shown in Figure 1, on the working face of steel matrix 4, be distributed with equidistant straight barrel-shaped oil pocket 5, bore aperture again between these oil pocket 5 bottoms, form oil duct, UNICOM each other, be plugged with film 2 on oil pocket 5 tops then, compound thereon again one deck macromolecular elastomer 1 is full of pressure oil and tightens oil-in with sealed screw 3 and be sealed to form in oil pocket 5, the shortcoming of said structure is:
When (1) before the composite sulfuration being the elastomeric material of liquid state on steel matrix 4, flowing into oil pocket 5 and stop up UNICOM's aperture for preventing this material, usually the tight certain thickness film of plug or the scraps of paper or stalloy etc. on oil pocket top.Under the condition of same elastomer thickness, because of being arranged, film exists, the working lining enlarged in thickness that elastic layer rises and falls, therefore, wait the static pressure effect to reduce.Because of press cure, film press to fall into and make compound elastomer thickness differ and the elastomeric material oil pocket that also can bleed, stop up UNICOM's oil duct, so waster often occurs.Be anti-leak-stopping glue, want time expand after the matched moulds pressurization, institute's plus-pressure can not be excessive, so, has influence on the adhesive strength between elastomer and the steel matrix working face again
(2) owing to adopt master mold down and give cast polyamine fat elastomer, at this moment steel matrix is last, and the problem that elastomer flowed into and stopped up oil pocket can obtain improvement, but adhesive strength is not improved, as adding film, needed pressure in the time of then can't forming the elastomer sulfuration, thus influence bond strength.
(3) because the composition surface that elastomer and steel matrix are gluedd joint is to bear positive tensile stress, and during splicing positive hot strength less than shear strength, so, elastomer takes place easily to come unstuck and cause the bubbling phenomenon.
(4) above-mentioned prior art can't obtain the necessary oil pocket structures of static pressure such as big plane.
The purpose of this utility model is to provide a kind of ceramic tile isostatic tooling, and it not only can obtain to wait the static pressure area big, waits the static pressure effect remarkable, and the elastomer long service life.
The purpose of this utility model is achieved in that a kind of ceramic tile isostatic tooling, comprise steel matrix, oil pocket, elastomer, equidistantly distribute one group of step oil pocket that connects each other on the described steel matrix working face or make the big plane groove shape oil pocket that periphery is provided with seal groove; Described elastomer precursor gum is connected on oil pocket step periphery or the seal groove periphery steel matrix, and elastomer bottom surface and step anchor ring distance are less than this oil pocket degree of depth, or the elastomer bottom surface equals this oil pocket degree of depth with big plane groove shape oil pocket bottom surface distance.The big plane groove shape oil pocket that above-mentioned periphery is provided with seal groove is made up of the plane groove shape oil pocket of seal groove one or one group of periphery that connects each other.
Compared with prior art, the utlity model has following advantage and good effect:
(1) oil pocket structure of the present utility model can guarantee that cavity pressure reaches under the situation of 30-40MPa when oil pocket is worked, the positive tensile stress that adopts prior art to occur can not appear between the splicing face of elastomer and steel matrix, be elastic shear stress but alleviate, like this, isostatic tooling just is not easy to occur glue and takes off phenomenon with bubbling.
(2) under the identical situation of elastomer thickness, existing ceramic tile isostatic tooling, because of the film that consent is arranged exists, the working lining enlarged in thickness that elastic layer rises and falls, therefore, reduced and waited the static pressure effect; And static pressure areas such as the utility model structure are big, also can be applicable to down to realize two-way grade for static pressure on the punch die, therefore, wait the static pressure effect remarkable.
Fig. 1 is the monoblock type isostatic tooling structural representation that existing a kind of ceramic tile is used.
Fig. 2 is the ceramic tile isostatic tooling structural representation of the step oil pocket structure of the utility model embodiment 1.
Fig. 3 is the ceramic tile isostatic tooling structural representation of a plurality of planes oil pocket structure of the utility model embodiment 2.
Fig. 4 is the ceramic tile isostatic tooling structural representation of the single big plane oil pocket structure of the utility model embodiment 3.
By following embodiment the utility model is further elaborated.
Embodiment 1:
Referring to shown in Figure 2, a kind of ceramic tile isostatic tooling is to equidistantly distribute one group of step oil pocket 7 that connects each other on steel matrix 4 working faces, it is bonding that elastomer 6 is deep into the peripheral steel matrix of step 8 and oil pocket 74, and the distance of elastomer 6 bottom surfaces and step 8 anchor rings is less than these oil pocket 7 degree of depth.
It is to adopt liquid the splicing that steel matrix 4 waits the elastomer bind mode of static pressure effect with generation.To impose the regulation operation pressure to sol during splicing and could correctly finish the splicing connection, for this reason, should be provided with supplementary structure support this pressure consistent below the sol and hold concurrently anti-sol seepage in oil pocket with elastomer 6 immersion oil face shapes, when solidifying and after splicing finishes, this supplementary structure should be able to conveniently be eliminated, must not occupy-place.
Embodiment 2:
Referring to shown in Figure 3, another kind of ceramic tile isostatic tooling is to be provided with one group of several plane groove shape oil pocket 10 on steel matrix 4 working faces, the periphery of each plane groove shape oil pocket 10 is equipped with seal groove 11, elastomer 9 is deep into seal groove 11 and bonding with this groove periphery steel matrix 4, form big plane groove shape oil pocket 10, this oil pocket bottom surface equals this oil pocket 10 degree of depth with the elastomer 9 bottom surfaces distance that is positioned at above the oil pocket 10.Steel matrix 4 is identical with example 1 with elastomer 9 bind modes.
Embodiment 3:
Referring to shown in Figure 4, the third ceramic tile isostatic tooling is to be provided with a big plane groove shape oil pocket 13 on steel matrix 4 working faces, its periphery is provided with seal groove 14, elastomer 12 is deep into seal groove 14 and bonding with this groove periphery steel matrix 4, and elastomer 12 bottom surfaces and oil pocket 13 bottom surfaces distance equal this oil pocket 13 degree of depth.Steel matrix 4 is identical with example 1 with elastomer 12 bind modes.
