Description
Technical field
The present invention relates to a kind of drying means of gypsum mold, and in particular to the building method of gypsum mold air passage.
Background technology
Gypsum mold in Production of Ceramics, for casting biscuit, gypsum mold absorbs the moisture in a large amount of biscuit of ceramics,
Help the biscuit of ceramics drying demoulding.But using the method spontaneously dried, speed is very slow, and the method needs of heat drying is used to disappear
Consume the substantial amounts of energy, it is thus proposed that improved method.Such as Chinese patent literature discloses a kind of fast rapid-curing cutback of gypsum mold
Drying method [application number：200910229324.1], preparation be in gypsum mold be equipped at least one air passage；Then to logical
Gas is passed through in air flue and carries out primary drying, gypsum mold is subjected to redrying afterwards, is down to water content in gypsum mold
≤20%.But using pre-buried flexible plastic tube when it makes air passage, the mode of extraction flexible plastic tube after gypsum mold is cured,
Such way, reduces the structural strength of gypsum mold, air passage also not intercommunication, and drying efficiency is high not enough.In in another example
State's patent document discloses a kind of pressurize-to-dry type gypsum mould [application number：200720061135.4], including by gypsum material
Manufactured die body, is provided with the permeability cell of more a diameter of 0.5~3cm among die body thickness, and permeability cell is in netted or pectination
Distribution, at intervals of 5~20cm, and between connect or commissure；Snorkel is additionally provided in die body, it can be defeated with air compressor
Outlet pipe accordingly connects.But its permeability cell is connected by non-woven fabrics or gauze winding, and junction does not have intensity, is not easy to make fitting mould
The rack of shape variation, structural strength is low, through-gauze of drying process or the easy aging fragmentation of non-woven fabrics of absorbing water repeatedly, such as
It passes to the higher air of temperature gypsum mold is dried, then non-woven fabrics or gauze service life are lower, and structure is webbed
It is simply ventilated with the aperture on tube wall between tracheae, not penetrated through really, air makes gypsum mold without smoothly flow channel is stablized
It is uneven by tolerance, influence drying effect.
The content of the invention
It is an object of the invention to provide a kind of building methods of air passage in gypsum mold, and air passage is by netted micropore
Copper pipe is formed, and steam hose is inserted into several air passages outlet being exposed on the outside of mold as air inlet, several outlets are the most
Exhaust outlet, pass to room temperature or 35-100 DEG C of hot air or compressed air, the air quickly flowed take away in gypsum mold
Moisture reduces the water content of biscuit of ceramics in mold, accelerates the speed of moulding adobe blocks of gypsum mold, improves production efficiency.
The present invention is achieved in that a kind of method that air passage is constructed in gypsum mold, including gypsum mold matrix, micro-
Hole copper pipe rack；Prefabricated micropore copper pipe rack is positioned in gypsum mold matrix, and copper pipe rack is stayed in the outer surface of mold
There is outlet, pass to air, micropore copper pipe rack integrally forms air passage in gypsum mold；The making material of gypsum mold matrix
For gypsum and composite gypsum material, gypsum and composite gypsum material or it is one of which or is several mixtures；The micropore copper
Pipe network frame is that one or several micropore copper pipes in gypsum mold matrix, copper pipe are evenly arranged according to the shape of gypsum mold
Spacing 2-30cm is communicated with one another in advance with the method for soldering, and the center line of longitudinal micropore copper pipe passes through residing plaster matrix position
Cross-section center line, the longitudinal section center line that the center line of horizontal micropore copper pipe passes through residing plaster matrix position；It is described micro-
A diameter of 0.1-10cm of hole copper pipe；The micropore of the micropore copper pipe, a diameter of 0.1-20mm；The gypsum mold air passage is
So formed：
It is characterized in that：
（1）Seal treatment immerses micropore copper pipe rack in 80 degrees Celsius or more the paraffin melted, and taking-up is placed in steel wire
It is cooled to room temperature on plate；
（2）Several half-dried plaster blocks are placed in the mould turnover for turning over molding jig, the thickness of plaster block is gypsum mold matrix
The half of bottom part thickness subtracts copper pipe radius, and the micropore copper pipe rack being welded is placed on plaster block, adjusts net
Rack position, the distance for making its distance left and right and front and rear mould turnover side plate is equal, places mold core, injects calcium plaster；
（3）After calcium plaster solidification, mold core and mould turnover are removed, gypsum mold matrix is obtained, puts it into baking oven, per half
10 degrees Celsius of hour heating, until when heat preservation 1 is small after 100 degrees Celsius, is slowly cooled to room temperature；
（4）Wax removal water is poured into micropore copper pipe rack reserves mouth in gypsum mold outer surface, is rinsed repeatedly several times,
It is dried up with compressed air, the construction complete of air passage；
Further, the air led in the air passage for room temperature or 35-100 DEG C of hot air or compressed air.
Further, when being passed through air in reserving mouth in mold outer surface to copper pipe rack, several outlets is selected to make
For air inlet, several outlets are left as exhaust outlet.
The present invention has the following advantages：
Air passage is communicated and reticulated by the welding of transverse direction and longitudinal direction micropore copper pipe, and copper pipe can be pre- according to the shape of gypsum mold
First design, be relatively evenly arranged in the centre position of gypsum mold matrix thickness, gypsum mold matrix position of different shapes by
Tolerance is more uniform, and drying efficiency is high；Netted micropore copper pipe skeleton needs not to be removed, forms the skeleton of gypsum mold, makes plaster mold
The structural strength of tool greatly improves, and repeats and utilizes, while the thermal conductivity factor of copper material is high, hot-air is passed through, to gypsum mold
Drying efficiency higher.
