Abstract
A kind of preparation method of new ceramics mold, specific production step are as follows: the first step cleans potsherd, dry, and crushes to be sufficiently mixed uniformly after powder with graphene, pours into colloid mill or sand mill and mills together；Second step adds water and stirs in the micro mist mixture made from the first step, and forms body of paste after being sufficiently stirred one hour；Above-mentioned body of paste is poured slowly into preprepared mould by third step, and the mould for filling body of paste is placed in kiln and is sintered；Ceramic mold of the present invention has quality firmer close, can once make molding compared with existing metal die；It eliminates metal die and the complicated procedures of forming such as needs continuous cold punching, forges and quench；Greatly reduce personnel cost and production cost.
Description
Technical field
The invention belongs to the manufacture technology fields of mold, and in particular to be a kind of new ceramics mold preparation method.
Background technique
During any product of production needs molding, require to use is product mold, can be made using mold
Production disposal molding, efficiency are very high；However at present most of product mold be all made of with metal material production and
At being difficult to carry out overmolded production, and metal to existing product since moldable property is poor under normal temperature conditions for metal material
Mold Making cost is big, is highly desirable to research and develop production of the new molding jig material of one kind to replace existing metal die.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of wide models of materials, can complete substituted metal mold
Ceramic mold production method.
The present invention is achieved by the following technical solutions: a kind of preparation method of new ceramics mold, is by following heavy
Measure the composition composition of part: potsherd 85% -98%, graphene 2% -8%；Specific production step is as follows.
The first step cleans potsherd, dry, and crushes to be sufficiently mixed uniformly after powder with graphene, pours into together
It mills, mills repeatedly 30-50 times in colloid mill or sand mill, be ground to nanoscale micro mist；
Second step adds water and stirs in the micro mist mixture made from the first step, and forms paste after being sufficiently stirred one hour
Body, for use.
The mould that above-mentioned body of paste is poured slowly into preprepared mould, and will fill body of paste by third step
Pattern tool places sintering in kiln, is warming up to 600 to 800 degrees Centigrade for the first time 2 hours, keeps the temperature 1 hour, is warming up to again
2500 to 3800 degrees Centigrades 2 hours, after heat preservation 1 hour, natural cooling opens mould and takes out ceramic mold, that is, makes
It finishes.
The beneficial effects of the present invention are embodied in compared with existing metal die, have quality more in: ceramic mold of the present invention
Add firm close, can once make molding；It eliminates metal die and the complexity work such as needs continuous cold punching, forges and quench
Sequence；Greatly reduce personnel cost and production cost.
Specific embodiment
A kind of preparation method of new ceramics mold, specific production step are as follows:
The first step weighs potsherd 90kg, graphene 10kg, potsherd is cleaned, dry, and crush be after powder with stone
Black alkene is sufficiently mixed uniformly, is poured into colloid mill or sand mill and is milled together, after milling repeatedly 45 times, is allowed to be ground to and be received
The micro mist of meter level.
Second step adds water and stirs in the micro mist mixture made from the first step, and forms paste after being sufficiently stirred one hour
Body, for use.
Above-mentioned body of paste, is poured slowly into preprepared mould that (mould refers to for needing by third step
Make which type of ceramic mold and special molding apparatus, ceramic mold needs carried out in mould disposably at
Type forms), and the mould for filling body of paste is placed in kiln and is sintered, it is small that it is warming up to 600 degrees Centigrades 2 for the first time
When, 1 hour is kept the temperature, is warming up to 2500 degrees Centigrade again 2 hours, after heat preservation 1 hour, natural cooling, out of mould
Ceramic mold is taken out, final ceramic mold is made, which can apply to each shaped article that needs
In industry.
Claims (2)
