Abstract

The utility model discloses a bidirectional isostatic pressing ceramic polishing brick mould comprising a mould base, a brick bottom isostatic pressing mould core and a brick surface mould core, wherein the brick surface mould core is a brick surface isostatic pressing mould core, the brick surface isostatic pressing mould core is formed by covering a layer of colloid on the inner surface of a mould core main body, a plurality of small oil cavities are arranged in the colloid, hydraulic oil is injected in the small oil cavities, and the small oil cavities are mutually communicated. Due to the adoption of the technical scheme, the bidirectional isostatic pressing ceramic polishing brick mould disclosed by the utility model has the beneficial effects that the pressure of the two mould cores is uniformly distributed during the transmitting process in the case of positive striking or negative striking to avoid the generation of low pressure region, high pressure region or dead angle, guarantee uniform density of the brick bottom and the brick surface and overcome such quality defects of the brick blanks generated during the sintering process as crack, delamination, deformation, large and small ends and constriction, etc.

Description

The two-way ceramic polished bricks die of static pressure that waits

Technical field:

The utility model relates to a kind of two-way ceramic polished bricks die of static pressure that waits.

Background technology:

Ceramic tile mold includes mould bases, brick face mould core, brick bed die core.Present Ceramic Tiles isostatic compaction is unidirectional isostatic compaction, the unidirectional static pressure that waits is with isostatic mould-core at the bottom of the brick, be that brick bed die core is isostatic mould-core, isostatic mould-core is at a plurality of small oil cavity of core rod colloid distribution at the bottom of the brick, the injection liquid force feed communicates between the small oil cavity in the small oil cavity, in the green brick forming process, every pressure is consistent, causes the bottom surface compact density of adobe consistent.

Tradition at the bottom of the brick etc. static pressure adobe molding mode be at static pressure such as brick bill kept on file faces, the density of adobe bottom surface is consistent, but in the powder forming process, the brick face does not wait static pressure, pressure forms low-pressure area or higher-pressure region sometimes at the skewness of transmittance process pressure, also has the dead angle, cause at the bottom of the adobe and the density of adobe face inconsistent, cause adobe to produce at sintering process and split the mass defects such as brick, layering, distortion, concentric reducer waisting.

Summary of the invention:

The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, and a kind of two-way polished bricks mould that waits static pressure is provided, and two-wayly refers at the bottom of the brick and brick face both direction, to reach the minimizing forming defect, and the beneficial effect that improves the quality of products.

Goal of the invention of the present utility model can realize by following technical scheme: the two-way ceramic polished bricks die of static pressure that waits, include isostatic mould-core and brick face mould core at the bottom of mould bases, the brick, and brick face mould core also is brick face isostatic mould-core.

Described brick face isostatic mould-core is to cover one deck colloid in the core rod body internal surface, is provided with a plurality of small oil cavities in the colloid, is injected with hydraulic oil in the small oil cavity, intercommunication between the small oil cavity.

After adopting the technical program, the beneficial effects of the utility model are: no matter be forehand or instead beat, the pressure of two core rods is evenly distributed at transmittance process, avoid forming low-pressure area, higher-pressure region or dead angle, make at the bottom of the adobe and the consistent in density of adobe face, overcome adobe and produce at sintering process and split the mass defects such as brick, layering, distortion, concentric reducer waisting.

Description of drawings:

Structure chart when Fig. 1 is counter beating such as the utility model ceramic polished bricks die of static pressure such as two-way grade;

Structure chart when Fig. 2 is ceramic polished bricks die forehand such as the utility model static pressure such as two-way grade.

The specific embodiment:

Below in conjunction with accompanying drawing present technique is described further.

The two-way ceramic polished bricks die of static pressure that waits of the present embodiment includes isostatic mould-core 2 and brick face mould core at the bottom of mould bases 1, the brick, and brick face mould core also is brick face isostatic mould-core 3.Brick face isostatic mould-core 3 is to cover one deck colloid 32 at core rod body 31 inner surfaces, is provided with a plurality of small oil cavities 33 in the colloid 32, is injected with hydraulic oil in the small oil cavity 33, intercommunication between the small oil cavity 33.

During the adobe forehand, isostatic mould-core 2 is as lower mold core at the bottom of the brick, and brick face isostatic mould-core 3 is upper mold core; Be that isostatic mould-core 2 is as upper mold core at the bottom of the brick during anti-beating, brick face isostatic mould-core 3 is as lower mold core.No matter be forehand or instead beat, the front of the adobe that obtains and the density of bottom surface, surface quality are consistent.

The above only is preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction.Any those of ordinary skill in the art, do not breaking away from the technical solutions of the utility model scope situation, all can utilize method and the technology contents of above-mentioned announcement that technical solutions of the utility model are made many possible changes and modification, or be revised as the equivalent embodiment of equivalent variations.Therefore every content that does not break away from technical solutions of the utility model, the equivalence of doing according to shape, structure and the principle of the utility model changes, and all should be covered by in the protection domain of the present utility model.
