C. chemical reaction does not take place in molding surface and opticglass when high temperature, can not adhere to glass;
D., high temperature oxidation does not take place;
E. good processability easily is processed into the profile of high precision and high surface finish;
F. cost is low.
The mould of machining high-precision opticglass product adopts wolfram varbide (Tungsten Carbide) or tungsten-cobalt carbide alloy usually.Yet the mould that is made by above-mentioned materials is after processing repeatedly, and its surface can become coarse because of oxygenizement, directly the quality of the opticglass product processed of influence.
For solving this technical problem, prior art adopts the method for chemical vapour deposition to deposit one β-SiC film on die surface.But this mould is adding the opticglass product of can adhering man-hour more than 400 ℃, make the opticglass product be not easy the demoulding.
For solving prior art problems, provide a kind of chemical stability good, and the mould of the opticglass product of can not adhering when the demoulding necessitate.
[summary of the invention]
The object of the present invention is to provide a kind of chemical stability good, and the mould of the opticglass product of when the demoulding, can not adhering.
Another object of the present invention is to provide a kind of chemical stability good, and the manufacture method of the mould of the opticglass product of when the demoulding, can not adhering.
For realizing purpose of the present invention, the invention provides a kind of mould of making the opticglass product, it comprises:
Die matrix and
Be positioned at the rete on this die matrix surface, this film material comprises diamond-like carbon, and thicknesses of layers is 50～200 dusts.
The present invention also provides a kind of method of making above-mentioned mould, and it may further comprise the steps:
One die matrix is provided;
At the surface deposition carbon of above-mentioned die matrix, make to form the diamond-like carbon rete that a thickness is 50～200 dusts at matrix surface.
Compared with prior art, the present invention is good in the diamond-like carbon film stratification inertia that the die matrix surface forms, and the erosion that can resist various acid, alkali and obnoxious flavour makes mould of the present invention when mold pressing, oxidizing reaction can not take place; Transparent, insulation strength is high, thermal conductivity good, hardness is high, frictional coefficient is low, during the demoulding can with opticglass product adhesion, and can protect die matrix injury-free, thereby improve the work-ing life of mould.In addition, thicknesses of layers of the present invention is 50～200 dusts, when forming this film, can obtain continuous film easily, and the wear resistance of rete is good, and during mold pressing opticglass product, deflection and induced stress are little, and repeatedly after the mold pressing, the rete difficult drop-off.

[embodiment]
The present invention is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, the invention provides a kind of mould 1 that is used for mold pressing aspheric surface glass lens, it comprises that a molded surface is aspheric die matrix 2 and the rete 3 that is positioned at die matrix 2 molded surfaces.Wherein die matrix 2 can be selected following material: SiC, Si, Si
3N
4, ZrO
2, TiN, TiO
2, TiC, B
4C, WC, W or WC-Co alloy.Rete 3 is that (Diamond Like Carbon, DLC), its thickness is 50～200 dusts to diamond-like carbon film.This diamond-like carbon film unreactiveness is good, can resist the erosion of various acid, alkali and obnoxious flavour; Transparent, insulation strength is high, thermal conductivity good, hardness is high, frictional coefficient is low; can not stick together the aspheric surface glass lens during hot press moulding; can guarantee the smooth demoulding of aspheric surface glass lens, and can protect die matrix 2 injury-free, thus the work-ing life of improving mould 1.In addition, rete 3 thickness of the present invention are 50～200 dusts, when forming this film, can obtain continuous film easily, and the wear resistance of rete 3 is good, and during the mold pressing non-spherical lens, deflection and induced stress are little, and repeatedly after the mold pressing, rete 3 difficult drop-offs.
See also Fig. 2, the present invention adopts radio-frequency sputtering (RF Sputtering) equipment 10 to form rete 3.Radio-frequency (RF) sputtering equipment 10 of the present invention comprises a vacuum chamber 11, its ground connection; One is positioned at the carbon material sputtering target 12 at vacuum chamber 11 tops; The one planar magnetic control sputtering rifle that is connected with sputtering target 12 (Magnetron Sputter Gun) 13, it comprises a cathode loop (figure does not show); One impedance matching circuit (Impedance Matching Circuit) 14 that electrically connects with magnetron sputtering rifle 13; One r-f generator that links to each other with impedance matching circuit 14 (RF Generator) 15, its ground connection; One be positioned at vacuum chamber 11 bottoms and with sputtering target 12 corresponding holders 16, be used for fixing die matrix 2; One is positioned at holder 16 belows and coupled anode electrode 17; The one electrode regulating circuit 18 that links to each other with anode electrode 17; One turbo-pump 19 is used for vacuum chamber 11 is evacuated; One family of power and influence 20 and two gases feed hole 21,22.Wherein holder 16 can link to each other with an engine (figure does not show) with anode electrode 17, and when forming rete 3 on die matrix 2 surfaces, engine can drive holder 16 and rotate with anode electrode 17.In addition, this holder 16 also comprises a tantalum line well heater (figure does not show), is used for heating mould matrix 2.
