Abstract

The utility model relates to a ceramic tile mould assembly. An upper mould frame is fixed outside an upper core and a lower mould core is sheathed with a lower mould frame to form an upper and a lower mould cavities, and the bottom of the lower mould frame is supported by an elastic stanchion. When the utility model works, adobe materials are filled in the lower mould cavity, the upper mould moves downwards, the mould frame presses the lower mould cavity to move downwards and the materials are pushed into the upper mould cavity and are pressed for molding. The mould causes the clean surface of the compressed adobe to be upward, improves the high quality rate of the product and reduces production cost because a tilting mechanism after the molding of the adobe is not needed.

Description

A kind of tile mould assembly

The utility model relates to ceramic tile shaping dies assembly.

Tile mould assembly commonly used, the moving platen on its top has the core rod of downward protrusion, has die cavity on the solid plate of bottom.During the ceramic tile press forming, the clean surface of the light of brick is downward, and brick back of the body line is towards last.Because though the adobe raw material is the powder attitude, but the part granule is also arranged, and in filling in adobe raw material process, the particulate form material flows freely suitablely than the powder attitude, often granule is distributed in the die cavity bottom, easily be mingled with colorant between particle, cause and burn till back coloured trace of brick face and color spot defective.In addition, die cavity bottom periphery easy adhesion heels grain and influence the unfired brick quality of next mould after the die sinking.According to the firing process requirement of ceramic tile, the brick face should make progress, and a cover switching mechanism also need be set after the adobe demoulding like this, and it is higher to make it cost, and efficient is on the low side.

The purpose of the utility model is to provide a kind of adobe factor of merit that improves, the tile mould assembly of enhancing productivity.

Tile mould assembly described in the utility model, form by upper die and lower die, the upper mold core of patrix is fixing outward framed, make upper mold core and last framed common formation upper cavity, lower mold core overcoat low mold frame, lower mold core and the low mold frame of counterdie constitute lower mode cavity jointly, a plurality of elastic supports are housed on the lower bolster support low mold frame.

The adobe powder was filled in lower mode cavity when described tile mould assembly was worked, the matched moulds process is that patrix descends, and goes up framed contact and compressing low mold frame, is elastic support because of what support low mold frame, low mold frame descends thereupon, and the brick stock enters upper cavity and is shaped under the extruding of upper and lower core rod.The light of adobe is washed one's face upwards.So, bring plurality of advantages.(1) with top is difficult look trace, the color spot of producing in the clean surface of light of adobe.Upper cavity is a forming cavity, and the salvage stores after the die sinking, in the die cavity falls naturally, easily keeps clean in the die cavity, can obviously improve the quality percentage of product.(2) light of adobe is washed one's face upwards, meets the requirement of sintering process naturally.Do not need to be provided with again the switching mechanism of adobe, can reduce production costs.(3) do not have the core rod of conventional mould and the friction between the die cavity wall, can improve die life.

The cutaway view of the described die assembly of Fig. 1;

The state diagram of Fig. 2 matched moulds.

The cope match-plate pattern of patrix A is equipped with upper mold core 21 time, and it is outer loads onto framedly 3, goes up the fixing framed side plate 4 in inboard of framed hollow bulb, and framed side plate 4 and the upper mold core 2 common spaces that surround are upper cavity 10.Dress push pedal 8 on the lower bolster 9 of counterdie B, fixing lower mold core 7 in the push pedal, lower mold core 7 places are with low mold frame 5, framed side plate 4 is fixed in the inboard of low mold frame hollow bulb, framed side plate 4 and the lower mold core 7 common spaces that surround are lower mode cavity 11, the elastic support 6 that is contained on the lower bolster 1 supports low mold frame 5, and low mold frame can move up and down along vertical line.Elastic support 6 can be a hydraulic prop, also can be spring strut.

Claims

1, a kind of tile mould assembly, form by patrix (A), counterdie (B), it is characterized in that: the upper mold core of patrix (2) outer fixing framed (3), make upper mold core (2) and last framed (3) constitute upper cavity (10) jointly, the outer low mold frame (5) that is with of the lower mold core of counterdie (7), lower mold core (7) and low mold frame (5) constitute lower mode cavity (11) jointly, a plurality of elastic supports (6) are housed on the lower bolster (9) support low mold frame (5).

2, by the described tile mould assembly of claim 1, it is characterized in that: the inboard fixing framed side plate (4) of the hollow bulb of upper and lower framed (3) (5).
