In recent years along with the development of science and technology progress, various optical articles comprise camera, digital still camera, Kamera, numerical digit Kamera, facsimile recorder, photoprinter, CD-ROM device, scanning machine and projector etc., continue to popularize gradually in general daily life under lifting and the continuous situation about descending of price in performance.
General optical articles all has accurate optical mirror slip element.And optical mirror slip can be divided into two kinds of spheric glass and aspherical lens usually.Wherein, spheric glass generally need use sphere correction eyeglass to come aberration for compensation, and the eyeglass that the Integrated lens group is used is more, weight is heavier.Otherwise aspherical lens can reduce the spherical aberration of spheric glass on optical effect, makes the quality-improving of eyeglass, and the eyeglass that the Integrated lens group is used is less, and weight is lighter.Therefore, application is very wide on optical articles.
From the above; in the manufacturing technology that has known aspherics glass mirror now; normally cooperate paired patrix and counterdie to form a die cavity with a mould or sleeve; utilize glass material to meet high temperature meeting remollescent characteristic; and by the pressurization program of patrix or counterdie, glass material mould model that will be in die cavity.Through after these processing procedures, on glass material, and the face pictograph of obtaining closes the optical glass lens of demand to the face shape on patrix surface and counterdie surface with transcription.Afterwards, again the optical glass lens of first one-step forming is got the core processing procedure after, can finish the making of optical glass lens.
Seeing also shown in Figure 1ly, is the structure cross-sectional schematic of existing known a kind of optical lens forming die.Existing known optical lens forming die 100 is the mould models that are applied to a glass nitre material 80.This optical lens forming die 100 comprises a mold 110 and a bed die 120.Wherein, mold 110 has a top mold surface 112.In addition, bed die 120 corresponding molds 110 are to form a die cavity 122, to place glass nitre material 80.This bed die 120 has a bottom mold surface 124, and wherein top mold surface 212 is identical with the surfaceness of bottom mold surface 224.
Please consulting simultaneously shown in Fig. 2 A to Fig. 2 C, is to have known a kind of optical lens forming die each step synoptic diagram to glass nitre material mould model now.At first; shown in Fig. 2 A; the existing known practice can be ground the face shape similar shape that becomes face shape and required glass mirror earlier with a glass nitre material 80 usually; be preform (Preform); again it is positioned on the die cavity 122 of bed die 120; and to these glass nitre material 80 thermoplastics, simultaneously with mold 110 pressing downwards gradually.
Then, shown in Fig. 2 B,,, therefore be easier to these glass nitre material 80 models are gone out to meet the face shape of demand because this glass nitre material 80 has ground to form a preform earlier when utilizing mold 110 with bed die 120 during with these glass nitre material 80 mould models.
Afterwards, shown in Fig. 2 C, mold 110 is separated with bed die 120, can obtain the glass mirror germule 80a that a pictograph closes demand.
In the above-mentioned practice, carry out model afterwards again owing to needing cost manpower and equipment earlier glass nitre material 80 to be ground to form the one side shape preform similar to the face shape of required glass mirror, therefore increased the production cost of glass mirror.
Please consulting simultaneously shown in Fig. 3 A to Fig. 3 C, is to have known another kind of optical lens forming die each step synoptic diagram to glass nitre material mould model now.In the existing known practice,,, can adopt the method for another kind of mould model to save the production cost of glass mirror in order to save the processing procedure that glass nitre material 50 is ground to form a preform earlier.At first, as shown in Figure 3A, directly place an oval-shaped glass nitre material 50 on the die cavity 122 of bed die 120, and with these glass nitre material 50 thermoplastics, simultaneously with mold 110 pressing downwards gradually.
Then, shown in Fig. 3 B, when mold 110 with bed die 120 during with these glass nitre material 50 mould models, because the roughness of bottom mold surface 124 equates with the roughness of top mold surface 112, so glass nitre material 50 equates with the flow rate of bottom mold surface 124 contact surfaces with the flow rate and the glass nitre material 50 of bottom mold surface 124 contact surfaces.Therefore, the part that glass nitre material 50 contacts with bottom mold surface 124 extends to both sides easily, if use the less glass nitre material 50 of volume, then the face shape 52a that goes out of model can't reach required shape.So need to use the bigger glass nitre material 50 of volume just can obtain required face shape 52b, to reach the effect of complete transcription.
Afterwards, shown in Fig. 3 C, mold 110 is separated with bed die 120, can obtain the glass mirror germule 50a that a pictograph closes demand.
Yet in the above-mentioned practice, during owing to mould model, the volume that glass nitre material 50 extends to both sides is bigger, so need to use the bigger glass nitre material 50 of volume, causes wasting the cost of glass nitre material 50.In addition, carrying out core when getting processing procedure, must spend the long time to remove the part that these extend to both sides.In addition,, cause the stroke of its face shape transcription bigger, and the time of mould and 50 frictions of glass nitre material is also longer, and then lowers the work-ing life of mould because glass nitre material 50 extends to both sides easily.
