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 tile molding die that prevents that steam vent from stopping up

Technical field:

The present invention relates to a kind of ceramic tile molding die that prevents that steam vent from stopping up.

Background technology:

Ceramic tile molding die is the industrial visual plant of Ceramic Tiles, Ceramic Tiles is powder moulding, in the time that upper and lower mould matched moulds is beaten brick, because mould coordinates closely, after matched moulds, inner air is difficult to timely discharge, make upper and lower mould matched moulds process produce powerful resistance, in order to address this problem, existing mould arranges a large amount of special steam vents on core rod matrix, but this steam vent accumulates a large amount of powders in due to hole in the process of producing, easily there is clogging, cause and produce after a period of time, usually need to shut down, the steam vent stopping up is carried out to cleaning work, otherwise the Forming Quality of Ceramic Tiles and shaping speed can be subject to great impact.

Summary of the invention:

The object of the invention is the shortcoming in order to overcome above-mentioned prior art, provide one can prevent all extraordinary ceramic tile molding dies of steam vent obstruction, shaping speed and Forming Quality.

For achieving the above object, technical scheme provided by the invention is: a kind of ceramic tile molding die that prevents that steam vent from stopping up, include core rod matrix, the working face of core rod matrix is stained with rubber layer, the static pressure oil reservoir such as between core rod matrix and rubber layer, be injected with, make the working face of its contact rubber layer and core rod matrix, on core rod matrix, be drilled with the steam vent that runs through in a large number rubber layer, in hole, be provided with the anti-blocking thimble that can make expanding-contracting action, between steam vent hole wall and anti-blocking thimble, leave exhaust clearance; Described working face is the back side of core rod matrix, in the time of mould matched moulds described in working face and rubber layer do not contact ceramic powder.

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

After said structure improves, utilization is plugged in the anti-blocking thimble in steam vent, after each complete Ceramic Tiles of moulding, anti-blocking thimble all can be made extend action, the head of anti-blocking thimble can stretch out steam vent completely, so just powder in steam vent can be discharged, prevent the obstruction of steam vent, make that Ceramic Tiles moulding is can be continuously uninterrupted, high-quality, carry out at high speed.

Brief description of the drawings:

Fig. 1 is the structural representation of ceramic tile molding die of the present invention;

Fig. 2 is the structural representation after ceramic tile molding die matched moulds of the present invention;

Fig. 3 is the structural representation while removing the interior powder of exhaust clearance after ceramic tile molding die die sinking of the present invention.

Detailed description of the invention:

Now elaborate by reference to the accompanying drawings the present invention:

The ceramic tile molding die that the prevented steam vent of the present embodiment stops up includes core rod matrix 1, the working face of core rod matrix 1 is stained with polyurethane rubber layer 2, the static pressure oil reservoir 3 such as between core rod matrix 1 and polyurethane rubber layer 2, be injected with, on core rod matrix 1, be drilled with the steam vent 4 that runs through in a large number polyurethane rubber layer 2, be socketed with tailstock barrel 5 in steam vent 4 exits, one anti-blocking thimble 6 pierces in steam vent 4, be provided with and drive it to make the device of expanding-contracting action at the installation end 61 of this anti-blocking thimble 6, the head 62 of anti-blocking thimble 6 is worn to the hole of tailstock barrel 5, between the inwall of tailstock barrel 5 and anti-blocking thimble 6, leave exhaust clearance 7, here the effect of tailstock barrel 5 is to come in contact with steam vent inwall for fear of anti-blocking thimble 6, prevent from occurring between them fretting wear, if tailstock barrel 5 weares and teares, can change tailstock barrel 5, thereby extend the service life of mould, in order further to improve the technical program, the non-operative end exit of steam vent 4 is connected with air pump.

Matched moulds is beaten before brick, the head 62 of anti-blocking thimble 6 is retracted in tailstock barrel 5, when matched moulds, air in die cavity is discharged from rapidly through exhaust clearance 7 and steam vent 4, ensure that mould assembling action completes fast smoothly, then after die sinking, drive unit starts, drive anti-blocking thimble 6 to make extend action, the head 62 of anti-blocking thimble 6 stretches out from tailstock barrel 5, in this extend 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 up hill and dale the powder in exhaust clearance 7, air pump starts blows, the powder of steam vent 4 and exhaust clearance 7 the insides is blown out completely, in last anti-blocking thimble 6 retraction tailstock barrels 5, wait for mould assembling action next time.

The above-mentioned description of this ceramic tile molding die being carried out with reference to embodiment is illustrative instead of determinate, therefore in the variation and the amendment that do not depart under invention general plotting, within should belonging to protection scope of the present invention.

Claims

1. the ceramic tile molding die that can prevent that steam vent from stopping up, include core rod matrix, the working face of core rod matrix is stained with rubber layer, the static pressure oil reservoir such as between core rod matrix and rubber layer, be injected with, make the working face of its contact rubber layer and core rod matrix, it is characterized in that: on core rod matrix, be drilled with the steam vent that runs through in a large number rubber layer, in hole, be provided with the anti-blocking thimble that can make expanding-contracting action, between steam vent hole wall and anti-blocking thimble, leave exhaust clearance; Described working face is the back side of core rod matrix, in the time of mould matched moulds described in working face and rubber layer all do not contact ceramic powder.

2. a kind of ceramic tile molding die that prevents that steam vent from stopping up according to claim 1, is characterized in that: be socketed with tailstock barrel in steam vent exit, between anti-blocking thimble and tailstock barrel, be preset with exhaust clearance.
