Abstract

The invention discloses a ceramic tile molding die capable of preventing vent holes from being blocked. The ceramic tile molding die comprises a die core substrate, wherein a rubber layer is stuck to the working surface of the die core substrate; an isostatic oil layer is injected between the die core substrate and the rubber layer; a large number of vent holes passing through the rubber layer are drilled on the die core substrate; an anti-blocking thimble capable of extending and contracting is arranged in each hole; a vent gap is reserved between the hole wall of each vent hole and each anti-blocking thimble; a thimble sleeve is sleeved at the outlet of each vent hole; and a vent gap is preformed between each anti-blocking thimble and each thimble sleeve. After the structural improvement, the anti-blocking thimbles which are spliced in the vent holes extend every time after a ceramic brick is molded, and the head parts of the anti-blocking thimbles completely extend out of the vent holes, so that powder in the vent holes can be discharged, the vent holes are prevented from being blocked, and ceramic tiles can be molded continuously at high quality and high speed.

Description

A kind of Ceramic Tiles mould that prevents that steam vent from stopping up

Technical field:

The present invention relates to a kind of Ceramic Tiles mould that prevents that steam vent from stopping up.

Background technology:

The Ceramic Tiles mould is the industrial visual plant of Ceramic Tiles, and Ceramic Tiles is the powder moulding, when the upper and lower mould matched moulds is beaten brick; Because mould cooperates closely, inner air is difficult to timely discharge behind the matched moulds, makes upper and lower mould matched moulds process produce powerful resistance; In order to address this problem, existing mould is provided with a large amount of special-purpose steam vents on the core rod matrix, but this steam vent accumulates a large amount of powders in the process of producing because in the hole; Clogging appears easily, cause produce a period of time after, usually need to shut down; Steam vent to stopping up carries out cleaning work, otherwise the Forming Quality of Ceramic Tiles and shaping speed can receive great influence.

Summary of the invention:

The objective of the invention is in order to overcome the shortcoming of above-mentioned prior art, a kind of all extraordinary Ceramic Tiles mould of steam vent obstruction, shaping speed and Forming Quality that prevents is provided.

For realizing above-mentioned purpose; Technical scheme provided by the invention is: a kind of Ceramic Tiles mould that prevents that steam vent from stopping up, include the core rod matrix, and the working face of core rod matrix is stained with rubber layer; The static pressure oil reservoir such as be injected with between core rod matrix and the rubber layer; Be drilled with the steam vent that runs through rubber layer in a large number on the core rod matrix, be provided with the anti-blocking thimble that to make expanding-contracting action in the hole, leave exhaust clearance between steam vent hole wall and the anti-blocking thimble.

Be socketed with tailstock barrel in the steam vent exit, be preset with exhaust clearance between anti-blocking thimble and the tailstock barrel.

After said structure improves; Utilization is plugged in the anti-blocking thimble in the steam vent, and after the intact Ceramic Tiles of each moulding, anti-blocking thimble all can do to stretch out action; The head of anti-blocking thimble can stretch out steam vent fully; So just can discharge the powder in the steam vent, prevent the obstruction of steam vent, make the Ceramic Tiles moulding can be continuously uninterruptedly, high-quality, carry out at high speed.

Description of drawings:

Fig. 1 is the structural representation of Ceramic Tiles mould of the present invention;

Fig. 2 is the structural representation behind the Ceramic Tiles mould matched moulds of the present invention;

Fig. 3 is the structural representation when removing powder in the exhaust clearance after the Ceramic Tiles mould of the present invention die sinking.

The specific embodiment:

Combine accompanying drawing to set forth the present invention in detail at present:

The Ceramic Tiles mould that the prevented steam vent of present embodiment stops up includes core rod matrix 1, and the working face of core rod matrix 1 is stained with polyurethane rubber layer 2, static pressure oil reservoir 3 such as is injected with between core rod matrix 1 and the polyurethane rubber layer 2; Be drilled with the steam vent 4 that runs through polyurethane rubber layer 2 in a large number on the core rod matrix 1, be socketed with tailstock barrel 5, one anti-blocking thimbles 6 in steam vent 4 exits and pierce in the steam vent 4; Be provided with at the installation end 61 of this anti-blocking thimble 6 and drive it and make the device of expanding-contracting action; The head 62 of anti-blocking thimble 6 is worn to the hole of tailstock barrel 5, leaves exhaust clearance 7 between the inwall of tailstock barrel 5 and the anti-blocking thimble 6, and the effect of tailstock barrel 5 here is to come in contact with the steam vent inwall for fear of anti-blocking thimble 6; Prevent to take place between them fretting wear; If tailstock barrel 5 weares and teares, can change tailstock barrel 5, thus the service life of prolongation mould; In order further to improve the present technique scheme, the non-operative end exit of steam vent 4 is connected with air pump.

Before matched moulds was beaten brick, the head 62 of anti-blocking thimble 6 was withdrawn in the tailstock barrel 5, during matched moulds; Air in the die cavity is discharged from rapidly through exhaust clearance 7 and steam vent 4, guarantees mould assembling action completion smoothly fast, then after die sinking; Drive unit starts, and drives anti-blocking thimble 6 and does to stretch out action, and the head 62 of anti-blocking thimble 6 stretches out from tailstock barrel 5; When this stretched out action, anti-blocking thimble 6 can be taken part out of and stay the powder in exhaust clearance 7, certainly in order further to clean out the powder in the exhaust clearance 7 up hill and dale; Air pump starts blows; Blow out the powder of steam vent 4 and exhaust clearance 7 the insides fully, in the last anti-blocking thimble 6 withdrawal tailstock barrels 5, wait for mould assembling action next time.

The above-mentioned description of this Ceramic Tiles mould being carried out with reference to embodiment is illustrative rather than determinate, therefore in the variation and the modification that do not break away under the invention general plotting, should belong within protection scope of the present invention.
