Abstract
The invention relates to a compressed drying-type gesso mould used for producing ceramic and relative preparation. Wherein, said mould comprises the body made from gesso; several vent tubes whose diameters are 0.5-3cm are arranged inside the wall of mould; said vent tubes are mesh or comb distributed while the distance is 5-20cm and nearby two are connected; and the mould also comprises vent pipes which are connected to the output tubes of air compressor. Said preparing method comprises: distributing the vent tubes into mesh or comb shape according to the shape of mould; arranging the vent tubes at the middle of wall; filling prepared gesso slurry into the mother mould with said vent tubes; when the gesso is completely solidified, removing the mother mould to attain needed mould. With said invention, the mould can be dried quickly, without limited by weather, to improve the producing efficiency; and since it can be dried without heating system or fan, it can save energy, reduce cost and reduce pollutions.
Description
Technical field
The present invention relates to mould and preparation method thereof, relate in particular to Production of Ceramics gypsum mold and preparation method thereof.
Background technology
Industrialized Production of Ceramics is extensive use of gypsum mold, can absorb a large amount of moisture content in the mould when notes are made primary production, and will use this mould to repeat to annotate when making, and just can reuse after then must waiting for the mould drying.For this reason, people use heated baking usually or carry out drying with the method that electric fan blows, and under general meteorological condition, need about 12 hours with the heating, drying method, and drying up rule with fan needs about 24 hours, and the mould drying is reused.The shortcoming of above-mentioned seasoning is that production efficiency is lower, and needs the more energy of additive decrementation, also can increase environmental pollution, and mould is impaired easily simultaneously, influences the service life of mould.
Summary of the invention
For overcoming the deficiency of traditional moulds, the invention provides a kind of mould rapid draing that makes, and the easy Production of Ceramics gypsum mold and preparation method thereof of operation control, can enhance productivity effectively, reduce production costs.
The present invention is achieved in that a kind of pressurize-to-dry type gypsum mould, comprises the die body of being made by gypsum material, and die body has die face one side and outer surface one side; Be provided with the permeability cell that at least one diameter is 0.5～3cm in the middle of the die body thickness, permeability cell is netted or pectination distributes, and is spaced apart 5～20cm, and between join or commissure; Also be provided with breather pipe in die body, an end and the permeability cell of breather pipe join, and the other end exposes outer surface one side of die body, and can correspondingly with the efferent duct of air compressor be connected;
As a further improvement on the present invention, described permeability cell can be metal tube or the plastic tube that has aperture on the sidewall, and available gauze swathes in this metal tube or the plastic tube outside.
Further improve as of the present invention, described permeability cell can madely in the gas permeable material outside have heart and the ventilative pipe of outer surface intercommunication by swathing with gauze, and arbitrarily bending or cut out.
Described gas permeable material can be to cut into the sponge of strip or fiber cloth, filament, cotton yarn, also can be the cauline leaf of plant drying, and with little iron wire above-mentioned bar material is concatenated into strip, makes made permeability cell crooked easily or cut out.
Described gas permeable material can be the bourdon tube that is rolled into by wire or rigid plastics silk.
Described gauze is cotton gauze or nonwoven.
The preparation method of pressurize-to-dry type gypsum mould, make with step as follows:
(1) will prick many uniform apertures on metal tube or the plastic tube sidewall, or gas permeable material sheared and wear and twine and conspire to create or be rolled into strip, with gauze above-mentioned bar material is swathed into the permeability cell that diameter is 0.5～3cm again with little iron wire;
(2) 2～10cm place, edge that is equivalent to be injection moulded body on master mold is interspersed with 2～4 spacer bars, and the termination of spacer bar has enough length to expose the outside of master mold;
(3) above-mentioned permeability cell is reticulated or pectination by the distribution of shapes that is injection moulded body, and between can be connected to each other or commissure, be spaced apart 5～20cm between the permeability cell;
(4) permeability cell extends to the spacer bar place and promptly is bundled into noose, and redundance is cut off;
(5) between permeability cell, join or the commissure place cuts off gauze, gas permeable material is contacted with each other, be rolled into one again with gauze again, and adjust the position of permeability cell, permeability cell is in be injection moulded the centre of body thickness;
(6) be sidelong at the outer surface one that is equivalent to be injection moulded body and put breather pipe, and an end and the permeability cell of breather pipe joined nearby, in the joint gauze is cut off, one end of breather pipe is contacted with gas permeable material, be integral with gauze parcel, the other end of breather pipe exposes and is injection moulded external surface one side again;
(7) with adjusting good calcium plaster injection, when the permeability cell distortion takes place, should correct rapidly, and once finish the cast of die body at short notice by the above-mentioned master mold that is provided with permeability cell;
(8) take out spacer bar fast when the gypsum semi-solid preparation, remove master mold and promptly make die body after gypsum solidifies fully, seal with calcium plaster at the reinforcing bar hole that will stay then on the made die body; Also can stay next hole as breather pipe.
When using gypsum mold of the present invention to carry out Production of Ceramics, after notes were made the primary production form removal, available mini air compressor was to the die body drying of pressurizeing.Its method is the efferent duct of air compressor to be inserted the breather pipe of die body, and remain on 1～8 atmospheric pressure, compressed air enters permeability cell by breather pipe, from the centre of die body to the both sides scattering and permeating, thereby the moisture content in the die body is discharged to the surface of die body both sides fast, continue about half an hour, can make die body dry and be used for once more annotating and make product.This method also can be injection moulded the body drying of pressurizeing to what just finished.
Realize the present invention, can make mould rapid draing, and not be subjected to the weather condition restriction, can enhance productivity greatly, save the workshop land used; Be specially adapted to relatively large ceramic product productions such as cleaners and polishes, can realize whenever slip casting round the clock 2～3 times, can realize that also the same day, molding was used for slip casting production the same day, carry previous week and go into operation; Because of not needing to use heating system or electric fan that mould is carried out drying, can save a large amount of energy resource consumptions again, reduce production costs, reduce air pollution and noise pollution.
