Abstract
The utility model discloses a mold core for isostatic pressing mold for ceramic tile molding, which comprises a mold core base body, wherein a rubber layer is arranged on the working surface of the mold core base body, a plurality of mutually communicated cavities are arranged in the rubber layer, and an oil inlet hole and an oil outlet hole are arranged on the mold core base body; one end of the oil inlet hole and one end of the oil outlet hole are positioned on the working surface of the mold core matrix, and the other ends of the oil inlet hole and the oil outlet hole are positioned on the bottom surface of the mold core matrix; the rubber layer is provided with a first communicating hole for communicating the oil inlet hole with the cavity and a second communicating hole for connecting the oil outlet hole with the cavity. The utility model discloses in when cloth thickness inconsistent everywhere in upper and lower die core working face nonparallel or the die cavity, pressure oil gets into in the cavity through the inlet port, plugs up the oil outlet, forces the die core shaping face to produce and warp, makes the adobe all receive equal pressure everywhere to obtain the even adobe of density everywhere, it is even to fire the in-process shrink, and the deformation of ceramic tile reduces greatly, and the yield that has improved ceramic tile and the protrusion string muscle are firm.
Description
Technical Field
The utility model relates to a pottery tile preparation field especially relates to fashioned mold core for isostatic pressing mould of pottery tile.
Background
When the planar ceramic tile is pressed into green brick with steel mold core, the forming surface is rigid and the surface shape is unchanged. Ceramic tile among the prior art because some functional demands can hang muscle or depressed part to the one side or the two-sided production of ceramic tile if hanging the needs of establishing function or outward appearance, this moment because the adobe thickness at each position is inconsistent, the suppression pressure can produce the difference, the thick position of powder receives the pressure in the die cavity is big, the power of the pressure that thin position received is little, the density that leads to the adobe is inhomogeneous, can influence the effect of burning into on the one hand, on the other hand can lead to the protrusion to hang the muscle not closely knit, be weak when the protrusion is hung the muscle and is used for hanging establishing, easy damage, lead to ceramic tile to drop.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a fashioned mold core for isostatic pressing mould of ceramic tile.
The utility model discloses an innovation point lies in the utility model discloses in when cloth thickness inconsistent everywhere in upper and lower die core working face nonparallel or the die cavity, pressure oil passes through in the inlet port gets into the cavity, plugs up the oil outlet, forces the die core shaping face to produce and warp, makes the adobe all receive equal pressure everywhere to obtain the even adobe of density everywhere, fire the in-process shrink evenly, the deformation of ceramic tile reduces greatly, the yield and the protrusion that have improved ceramic tile hang the muscle firm.
In order to realize the purpose of the utility model, the technical proposal of the utility model is that: a mold core for an isostatic pressing mold for ceramic tile molding comprises a mold core base body, wherein a rubber layer is arranged on the working surface of the mold core base body, a plurality of mutually communicated cavities are arranged in the rubber layer, and an oil inlet hole and an oil outlet hole are formed in the mold core base body; one end of the oil inlet hole and one end of the oil outlet hole are positioned on the working surface of the mold core matrix, and the other ends of the oil inlet hole and the oil outlet hole are positioned on the bottom surface of the mold core matrix; the rubber layer is provided with a first communicating hole for communicating the oil inlet hole with the cavity and a second communicating hole for connecting the oil outlet hole with the cavity.
Furthermore, a glue fixing groove is formed in the working surface of the mold core base body, glue is arranged in the glue fixing groove, and the rubber layer is adhered to the working surface of the mold core base body through the glue in the glue fixing groove. The rubber layer is connected more firmly.
Furthermore, the rubber layer comprises a first layer of rubber and a second layer of rubber, wherein the opposite surfaces of the first layer of rubber and the second layer of rubber are provided with concave ribs and convex ribs which are matched with each other, and the concave ribs and the convex ribs are mutually inserted and adhered; the first layer of glue is connected with the working surface of the mold core base body, and the first communicating hole and the second communicating hole are both arranged on the first layer of glue.
The utility model has the advantages that: the utility model discloses in when cloth thickness inconsistent everywhere in upper and lower die core working face nonparallel or the die cavity, pressure oil gets into in the cavity through the inlet port, plugs up the oil outlet, forces the die core shaping face to produce and warp, makes the adobe all receive equal pressure everywhere to obtain the even adobe of density everywhere, it is even to fire the in-process shrink, and the deformation of ceramic tile reduces greatly, and the yield that has improved ceramic tile and the protrusion string muscle are firm.
