Abstract

The invention relates to a production method for a quick forming sanitary ceramic die. The technical scheme comprises the following steps of: (1) manufacturing a mother die; (2) manufacturing a quick forming die; and (3) installing the die. The invention discloses a method for manufacturing the quick forming sanitary ceramic die. A pipe network is not buried, drain channels similar to the pipe network are formed in the die through certain technology, the molding cycle is greatly shortened, the molding cost and energy consumption for drying the die are reduced, the service life of the die is prolonged, the work efficiency is improved, and the labor environment of workers is improved. The die doubles the forming frequency per shift, and improves to two shifts from one shifts in each workday, and the area of a forming workshop and the number of used dies are greatly reduced, so the one-time investment, the rejection rate of the die, waste die treatment cost, total solid waste amount and the like are greatly reduced.

Description

A kind of production method of quick shaping sanitary ceramics mould

One, technical field

The present invention relates to a kind of production method of quick shaping sanitary ceramics mould.

Two, prior art

China's sanitary ceramics annual production in 2009 has reached 1.6 hundred million, ranks first in the world.The sanitary ceramics forming technique is except that minority enterprise uses high pressure slip casting, the sanitary product of all the other most sanitary ceramics manufacturing enterprises all adopts the gypsum mold casting, the forming period majority is 1 class/day, 1 time/class, the minority product that has only only a few factory is with discontinuous mode slip casting 2 times/class, and forming efficiency is very low, in addition owing to need drying die and base substrate, hot and humid environment is adopted in the workshop usually, has a strong impact on workman's physical and mental health, has also consumed a large amount of energy simultaneously.

Afterwards, minority enterprise has introduced fast draining forming technique of low pressure and equipment, but because its Mold Making more complicated, need to make earlier auxiliary mould, trouble is to bury filter screen in mould underground the most, and the material of filter screen never well solves, and makes the fabrication cycle prolongation and the Mold Making cost of work mould also improve 30-50 unit/cover than common composite pouring, thereby the popularization of this achievement is greatly limited.

Patent CN101700674A discloses the quickly drying method of gypsum mold, is provided with at least one breather line in gypsum mold, but this method is only to be used for drying die, and is not used in the quick shaping of sanitary ceramics.

Three, Fa Ming content

Purpose of the present invention provides a kind of production method of quick shaping sanitary ceramics mould at the weak point of conventional art

For realizing purpose of the present invention, technical scheme of the present invention is like this:

(1), the making of master mold:

On the master mold of producing normal use, transform, in foreign countries, need to beat the circular hole of some Φ 10--12mm according to the shape of product, the circular hole spacing is 5--6cm, the plastic tube of interpolation Φ 10--12mm or stainless steel tube, the wire that cover easily formalizes in the pipe, the pipe infall bundlees with fine wire, makes the mutual infall contact of tube and tube, forms network structure.

(2), the making of shaping dies fast

In master mold, work out drainage pipeline networks, inject calcium plaster, before final setting of plaster slip finishes, the plastic tube in the plaster mold is extracted together with the setting wire, in plaster mold, stay the drainage pipeline that is interconnected, the outlet of extracting end out is blocked with gypsum; To the draining of work mould blowing compressed air, compressed air hose is connected the drainage pipeline that leaves on the mould behind the demoulding, pressure 0.2---0.3MPa, makes the mould dehydration at 30 minutes time.

(3), mould is installed

On the basis of conventional combination pouring product line, increase the air blowing of a Φ 20mm and vacuumize dual-purpose pipeline, some hard high-pressure plastic arms that are connected with mould are installed on the pipeline, diameter is about Φ 10mm, after mould is placed in frame, each arm is connected with each mould successively gets final product.

Adopt the present invention of above-mentioned preparation production method to have following effect:

(1), mold material adopts the used material of traditional ceramics mould----gypsum, low price, aboundresources;

(2), overcome in the fast draining forming technique of the original low pressure mould bury pipe network, molding difficulty underground, the moulding cycle is long, relative cost is high, the disadvantage that be difficult for to realize on complex product, do not bury pipe network underground but adopt, make the drainage channel that forms similar pipe network in the mould by certain technology, shortened the moulding cycle greatly, molding expense and the used energy consumption of drying die have been reduced, improve die life and operating efficiency, improved workman's work situation;

(3), compare with common composite pouring shaping, use mould of the present invention to make per tour shaping number of times improve 2-3 doubly, every workday is brought up to 2-3 class by 1 class, therefore work efficient had improved 6-9 doubly in actual day, the area of molding room and to use number of molds to be reduced to original about 1/6 like this, institute is so that one-time investment and mould scrappage, useless mould processing cost, solid waste total amount etc. reduce greatly;

(4) though formed no pipe network drainage channel in the mould, make draining faster.

Five, the specific embodiment

Quick shaping sanitary ceramics mould of the present invention is a kind of inner mould that forms the drainage channel of similar pipe network.

Embodiment 1

Shape according to product, at the circular hole of beating in the foreign countries of product master mold about some spacing 5cm, diameter of phi 10mm, the wire that cover easily formalizes in the plastic tube of interpolation Φ 10mm or the stainless steel tube, plastic tube, the plastic tube infall bundlees with fine wire, makes the mutual infall contact of plastic tube.Pour calcium plaster then into, treat before the final setting of plaster slip end plastic tube in the plaster mold to be extracted together with the setting wire, make the passage that forms similar pipe network in the gypsum mold, will extract stomidium again out and block up.Demoulding needs later on the draining of work mould blowing compressed air, and pressure 0.3MPa, makes the mould dehydration at 30 minutes time.It is a kind of well quick shaping dies.

Embodiment 2

At the circular hole of beating in the foreign countries of product master mold about some spacing 6cm, diameter of phi 8mm, the wire that cover easily formalizes in the plastic tube of interpolation Φ 8mm or the stainless steel tube, plastic tube makes the mutual infall contact of plastic tube.Pour calcium plaster then into, treat before final setting of plaster slip finishes the plastic tube in the plaster mold to be extracted together with the setting wire, will extract stomidium again out and block up.Also can produce qualified quick shaping dies.
