Abstract
The utility model relates to a pressing-forming mould for a ceramic tile, which comprises an upper and a lower mould cores respectively positioned in an upper and a lower mould side plates. The utility model is characterized in that at least one of the upper and the lower mould cores is provided with an exhaust passage which is communicated with a powder filling cavity between the upper and the lower mould cores. The utility model has the advantages that exhaust time is shortened, the speed of pressing an adobe to be formed is enhanced, and the uniformity and the compactness of the density of the adobe can be improved.
Description
The utility model relates to a kind of mould that powder is pressed into ceramic adobe.
Powder is pressed into ceramic adobe in mould.The adobe volume that is pressed into is about 40% of the preceding free packing volume of powder of compacting, has a large amount of air to be extruded discharge in the powder.In prior art, because the air in the powder can only (being the periphery of base substrate) be discharged gradually from the gap between core rod and the mould side plate, therefore when brick body specification is big, the base substrate center is just far away to the distance of periphery, causes the exhaust resistance of forming process big, evacuation time is long, shaping speed is slower.In addition because the base substrate center is different with the exhaust resistance of periphery, so cause the density at the base substrate center of making and edge inconsistent, and then cause base substrate in follow-up polishing, polishing process, easily to break, and the stamp color is inhomogeneous.Brick body specification is big more, and above-mentioned shortcoming is outstanding more.
The purpose of this utility model provides a kind of Ceramic Tiles press-moulding die that can more promptly discharge the air in the powder when the press ceramic adobe.
The utility model is achieved in that the Ceramic Tiles press-moulding die comprises upper mold core and the lower mold core that lays respectively in the upper and lower mould side plate.The utility model has the exhaust passage at one of upper and lower core rod at least, the powder filling cavity UNICOM between described exhaust passage and the upper and lower core rod.After setting up above-mentioned exhaust passage, the air in the powder can be discharged from the exhaust passage, has therefore compared with the prior art reduced exhaust resistance, has improved exhaust velocity.The base substrate specification is big more, and the exhaust passage of being set up is obvious more to reducing the exhaust resistance role.
The utility model has the advantages that: owing to shortened evacuation time, and reduced the density inconsistency at base substrate center and edge, so improved production efficiency and improved the uniformity of adobe density.Owing to reduced exhaust resistance, the air in the base substrate is discharged more up hill and dale in addition, therefore make the adobe that is pressed into finer and close.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1, the upper mold core 1 of Ceramic Tiles press-moulding die and lower mold core 2 lay respectively in the upper and lower mould side plate 3,4.In the present embodiment, in upper and lower core rod, all offer many exhaust passages 5.Powder filling cavity 6 UNICOMs between each exhaust passage and the upper and lower core rod.During pressing unfired brick, the air in the powder is discharged along the direction of arrow in the figure through the exhaust passage.Present embodiment all offers many exhaust passages in upper and lower core rod, so more help discharging the air of different parts in the base substrate, accelerate exhaust velocity, and make the exhaust resistance at each position of adobe basic identical, further improve the uniformity of adobe density, and more can improve adobe compactness, thereby make adobe in follow-up polishing, polishing process, be difficult for breaking, and the stamp color is more even.When the bigger brick body of compacting specification, above-mentioned advantage is more outstanding.The quantity of exhaust passage can determine that general brick body specification is big more by normal experiment, and the quantity of offering is many more.Desirable 1～the 10mm in the aperture of exhaust passage.For example suppress the Ceramic Tiles that specification is 800mm * 800mm, can offer 5～10 apertures respectively in upper and lower core rod is that 1～10mm (is preferably 2～5mm) exhaust passage.
Claims (2)
1. Ceramic Tiles press-moulding die, comprise the upper mold core and the lower mold core that lay respectively in the upper and lower mould side plate, it is characterized in that: have the exhaust passage at one of upper and lower core rod at least, the powder filling cavity UNICOM between described exhaust passage and the upper and lower core rod.
2. Ceramic Tiles press-moulding die as claimed in claim 1 is characterized in that all offering in the upper and lower core rod many exhaust passages.
