Described in the aspect ratio of described slider body 221, each projection 211 is on described die main body 21
The most slightly higher.
Described protuberance 222 grows towards the extension of this shaping area A from this slider body 221.
Making when engaging with this die main body 21 in this slide block 22 slips into this chute 212, this highlights
Portion 222 protrudes from the interior edge of this shaping area A.In the present embodiment, described protuberance 222
Including teat top along 2221 with teat inclined-plane 2222.Described teat top is positioned at prominent along 2221
Portion 222 is away from a side of described slider body 221, and described teat top is along the shape of 2221
Shape agrees with mutually with the shape of die 213 upper surface at corresponding shaping area A.Described
Teat top along 2221 include connecting with shaping area A lower along 2221b and relatively under this along 2221b
More towards shaping area A protruding outside on along 2221a.The upper edge along 2221, the described teat top
The position of 2221a slightly highlights the interior edge of corresponding shaping area A, and described teat top is along 2221
Lower agree with mutually along the position of 2221b and the interior edge of corresponding shaping area A.Teat is oblique
Face 2222 is the tangent plane that the two ends along described teat top along 2221 extend to both sides, the most adjacent
Teat inclined-plane 2222 be mutually butted, and the gap between them is less than 0.2 millimeter.This is dashed forward
Going out and form a hierarchic structure between portion 222 and slider body 221, this hierarchic structure is as spacing
Portion 223.The ladder knot formed between this limiting section 223 and this die 213 and this chute 212
Structure abuts, thus plays position-limiting action.
The material of described mould 2 selects free hexagonal boron nitride (HBN), silicon oxide (SiO2)、
Aluminium oxide (Al2O3), the porous heatproof that formed of hexagonal crystal system layer carbon (C) and combinations thereof
Material, its density is between 1.5g/cm3To 6.5g/cm3Between, pore size is between 0.2 nanometer
Between 2 microns, heat-resisting indeformable operating temperature is Celsius between 650 degrees Celsius to 1600
Degree.
As shown in Figure 6, the flow chart of the method for three-dimensional glass is prepared for the above-mentioned mould 2 of use.
Step S201, is placed in the die 213 of the mould 2 assembled by the material preparing glass
In.Preferably, this prepares the material of glass selected from passing through chemical mode or thing after shaping
Reason mode carries out the glass material of strength of glass enhancing, such as soda-lime glass, aluminosilicate system glass
Glass, alkali-free glass, boron glass and combinations thereof thing etc..
Step S202, heats described glass material and mould 2.Specifically, can be by described Sheng
The mould 2 having glass material heats as in glass forming furnace, and the temperature of heating is not less than
600 degrees Celsius.
Step S203, after described glass material softens, applies the glass after external force order softens
Material is tightly attached on mould 2.Specifically, mould of the present invention 2 is by porous
Temperature-resistant material is made, and bleeds substrate 210 from the side, substrate 210 place of mould 2.By
It is to be formed by porous temperature-resistant material in described mould 2, from substrate 210 place of mould 2
Bleed and can form vacuum between glass material and mould 2 in side so that the glass after described softening
Material is attached on described mould 2 tightly.
Step S204, after glass material is attached at described mould 2, cools down described glass element
Material is to form the three-dimensional glass of solidification.
Step S205, is separated described each slide block 22 with die main body 21, to take out
State three-dimensional glass.Design by separating type die 2 of the present invention, it is possible to preparation edgewise bend surpasses
Cross the three-dimensional glass of 90 degree, and can the most easily solid glass be taken from mould 2
Go out.
The mould of the present invention is not limited only to the manufacture of three-dimensional glass shown in Fig. 1, for forming bending
The three-dimensional glass of the angle bending shape more than 90 degree is the most applicable, as long as according to three-dimensional glass
Concrete shape change shaping area shape.
Above example is only in order to illustrate technical scheme and unrestricted, although with reference to relatively
The present invention has been described in detail by good embodiment, and those of ordinary skill in the art should manage
Solve, technical scheme can be modified or equivalent, without deviating from the present invention
The spirit and scope of technical scheme.
