Abstract

The utility model provides a pressure-drying plaster mold for ceramic production. The pressure-drying plaster mold comprises a mold body which is made of plaster material; a plurality of vent pipes with the diameters of 0.5 to 3cm are arranged in the middle of the thickness of the mold body; the vent pips are distributed in a shape of net or comb at the intervals of 5 to 20cm; and the vent pipes are mutually connected or cross-connected. A ventilation pipe is further arranged in the mold body and can be correspondingly connected with an output pipe of an air compressor. The realization of the pressure-drying plaster mold can quickly dry the mold without the limitations by the weather conditions, thereby greatly improving the production efficiency, saving the workshop occupying space and being particularly applicable to the production of larger products, such as sanitary ware, etc.; as the pressure-drying plaster mold does not required to be dried by a heating system or an electric fan, the pressure-drying plaster mold can greatly save the energy consumption, lower the production cost, and reduce the air pollution and the noise pollution.

Description

A kind of pressurize-to-dry type gypsum mould

Technical field

The utility model relates to a kind of mould, relates in particular to the Production of Ceramics gypsum mold.

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 utility model provides a kind of gypsum mold that is used for Production of Ceramics, can make mould rapid draing, and operation control easily, can enhance productivity effectively, reduces production costs.

The utility model 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.

When using gypsum mold of the present utility model 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 utility model, 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.
