Description
Technical field
The present invention relates to glass working arts fields, set more particularly to a kind of deoxygenation dust-extraction unit, a kind of hot bending shape
Standby and a kind of deoxygenation dust removal method.
Background technique
With emerging for curved surface mobile phone faceplate, people increasingly pursue curve screens panel.Existing common mobile phone 3D
Bend glass molding substrate method and step are as follows: 1. at room temperature, under air environment, 2D planar glass substrate is manually put into shaping mould
In tool；2. the molding die for loading glass is put into sealing, isolation ward full of nitrogen and carries out deoxygenation；3. in molding room
Substep is shaped to 3D bend glass substrate by preheating, hot bending, slow cooling；4. subsequently cooling to room temperature；5. room temperature servant
Work point mould takes out molding 3D bend glass substrate, then carries out next circulation.
The material of molding die is mainly graphite, and it is more than 350 DEG C or more easy to oxidize that the characteristic of graphite material, which is temperature, and
The hot bending temperature of glass is at 700 DEG C or more.Therefore it is filled with protective gas nitrogen in 3D glass forming process, is contained with reducing oxygen
Amount, prevents the oxidation of graphite jig.
Production has the drawback that at present: when artificial loading glass is to molding die, room temperature and air environment it
In.It is general to use in order to guarantee gas displacement in mold cavity when molding die is filled with nitrogen progress deoxygenation in investment isolation cabin
Ventilation slot is equipped on mold, after the mold with ventilation slot enters in molding room, due to nitrogen flow, dust is viscous with air-flow
It is attached to glass, mould inner surface, so that the defects of glass surface generates point in forming process.
If mold cavity good seal performance, the oxygen sealed in mold cavity is not easy to be cemented out completely by nitrogen, and
And the gap of graphite jig also remains a certain amount of oxygen.The oxygen in the gap of graphite jig is contained at high temperature to graphite jig
Surface aoxidized, mould strength reduce and surface texture become loosely, to influence 3D bend glass surface quality, simultaneously
Reduce the service life of mold.
Summary of the invention
