Description
Technical field
The present invention is about a kind of plating Mo technology of mould core for moulding glass, particularly relevant for a kind of method of the cured film plated film precision that can improve the glass moulding die and realize the tool of this method.
Background technology
In the processing procedure of glass moulding, one of most important factor that influences the processing procedure success is the plated film step of die surface hardening film wherein.The success or failure of this cured film plated film step are then concerning the surface quality of produced glass mirror.In addition, in the work-ing life of used die, this also can influence its manufacturing cost when the operation of cured film plated film was also concerning glass moulding.
At present, the cured film film coating method of general mould core for moulding glass mainly is with physical vapor deposition (Physical Vapor Deposition, PVD) be main, for example evaporation (Evaporation), sputter (Sputtering), ion film plating (Ion Plating) etc.These processing procedures all can form the sclerosis plated film effectively on the surface of die.
But, in process of plating, often must promote the plated film efficiency of operation by means of the use of tool, boost productivity.Tool commonly used and being applied in the plated film operation, equal some shortcomings, relatively poor as degree of eccentricity, plated film easily peels off on die, the processing procedure homogeneity is not good, cured film coats undercapacity, die external diameter low precision or be difficult for carrying out precision sizing etc.
What Fig. 1 was shown is a kind of existing mode of using in the operation of glass stamper plated film of plating Mo tool and application thereof.As shown in the figure, in the plated film operation of glass stamper, it is to have adopted a film coating jig 100.This film coating jig 100 can be a plate object, or square, and is perhaps circular, has first surface 102, and second surface on the other side 104.For convenience of description, hereinafter first surface 102 is called the surface, top, second surface 104 then is a surface below.Need to prove that " top " reaches the definition of directions such as " belows " here, only for convenience of explanation for the purpose of, there is no inevitable relation with the present invention's application actually.And be noted that simultaneously definition that " top " here reaches " below " also is applicable to the full content of this specification sheets.
Be formed with a plurality of die cavitys 106 in the film coating jig 100, extend to second surface 104 from first surface 102.Hereinafter for convenience of description for the purpose of, this direction (i.e. the direction of extending between surface and surface below up) will be called axial direction due, and perpendicular to this axial direction due, and the direction that is parallel to surface, top and surface below then is called radial direction.
In graphic, for simplicity, only demonstrate a die cavity 106.But this technology can be applied in the situation of single die cavity, also can be applied on the arbitrary die cavity in a plurality of die cavitys.
In each die cavity 106, can insert a die 108, have position coated surface (not indicating) up, the Coating Materials deposition be formed one deck sclerosis plated film 110 thereon with aforesaid physical vapor deposition.Die 108 has a correcting portion 112, its shape and size make it closely to be inserted in the die cavity 106 and extend along axial direction due, its surface, top is then outstanding to expose to outside the first surface (surface, top) 102 of film coating jig 100, and the coated surface of formation die 108, can be thereon for cured film 110 depositions.
In operation, the thickness of tabular film coating jig 106 (being meant its size 104 of first surface 102 and second surfaces at this) (means die 108 size in the axial direction at this than the height of die 108, promptly with the unidirectional size of the thickness of film coating jig 106) little, therefore the coated surface of die 108 is after die correcting portion 112 inserts in the die cavity 106, and the evagination that can make progress is outside the first surface 102 of film coating jig 100.
Be formed with an overhead kick portion 114 on the end below the die 108 correcting portions 112, form a stage portion between the bead 116 that it is radially outward outstanding and the below end of correcting portion 112, can be resisted against along the lower edge of die cavity 106 on the surface below 104 of film coating jig 100, and then die 108 is fixed on the tool 100.In addition, below overhead kick portion 114, be provided with a baffle plate 118, be pressed against in the overhead kick portion 114, further die 108 is fixed in the die cavity 106.
This prior art can die 108 evaginations in surface above the tool 100 outside 102 above form the plated film 110 of one deck coated on the coated surface, so plated film 110 can have bigger coating intensity.Outside the surface 102 yet sizable amount is arranged because die 108 protrudes on the tool 100, so the external diameter that the correcting portion 112 of die 108 has some exposes out.In the plated film operation, can on the external diameter of correcting portion 112, form the big and relatively poor external diameter plated film of uniformity coefficient of thickness, shown in external diameter plated film 120 unavoidablely.
In the molded operation of this die 108 of subsequent applications, as shown in Figure 2, when the die of so making 108 inserts in the hole 902 set in the mould 900, uneven external diameter plated film 120 can make die 108 produce phenomenon eccentric or that tilt on correcting portion 112 external diameters, that is the axial line 122 of die 108 can depart from the axial line 904 in mould hole, or relative tilt.When serious, even utilize the overhead kick portion 114 of die 108 itself, and the template 906 etc. with the function that is similar to baffle plate 118, also can't correct.Therefore, this die can't be applied in the higher processing procedure of concentricity requirement, simultaneously in follow-up assembling or processing operation, external diameter plated film 120 on die 108 external diameters, also can be relatively poor because of its tack with respect to smooth die face, and make it be easy to peel off, have influence on the yield of glass moulding processing procedure.
Moreover surface, die top protrudes in outside the surface, tool top a lot of, can have influence on the processing procedure homogeneity of physical vapor deposition, can cause adverse influence for the quality of plated film equally.
Demonstrate another kind of prior art among Fig. 3, be provided with the die cavity 106a that runs through between surperficial up 102a of wherein tabular tool 100a and the surface below 104a.In die cavity 106a, insert die 108a.By aforesaid various physical vapor depositions, can on coated surface above the die 108a, form one deck plated film 110.In this prior art, the height of die 108a is about as much as the thickness of tool 100a, so rough surface, the top 102a with tool 100a of the top coated surface of die 108a is concordant.But on the top edges of die cavity 106a, offer endoporus edge chamfer 124, mat and expose a part of external diameter position of the correcting portion 112 of die 108a, so in the plated film operation, on the external diameter position that this exposes outside, can deposit external diameter plated film 120a.But the degree of depth of this external diameter plated film 120a (i.e. size on the die 108a axial direction due) can be subjected to the restriction of chamfering 124 degree of depth, and therefore compared to technology shown in Fig. 1, its external diameter plated film 120a can be littler than the external diameter plated film 120 among Fig. 1.
This kind plated film mode can make on a part of external diameter of the coated surface of the die 108a that plated film adheres to and die correcting portion 112, so the coating intensity of plated film is kept.Die 108a still has phenomenons such as off-centre or inclination in follow-up molded operation, only comparatively relax than the prior art shown in Fig. 1 but similarly.
In addition, though the coated surface of die 108a is concordant with the surface 102, top of tool 100a, but improve the processing procedure homogeneity of physical vapor deposition effectively, but this external diameter plated film 120a still can cause adverse influence for the yield of model processing procedure.
Figure 4 shows that another kind of prior art, offer the die cavity 106b that runs through between surperficial equally up 102b of wherein tabular tool 100b and the surface below 104b, can insert in it for die 108b.The height of die 108b is about as much as the thickness of tool 100b, so rough surface, the top 102b with tool 100b of the top coated surface of die 108b is concordant, and is different from the technology among Fig. 3.On the top edges of die cavity 106b, do not offer the endoporus edge chamfer, so successive plane of the common formation of 102b, surface, the top of the top coated surface of die 108b and tool 100b.By aforesaid various physical vapor depositions, can on this continuous surface, form one deck successive plated film 110.This kind plated film mode can make the coated surface of the die 108b that plated film only adheres to, and can therefore can not improve the homogeneity of physical vapor deposition processing procedure attached on the footpath outside the die correcting portion 112, and then can obtain the plated film of higher quality.Yet, because of not coating to the external diameter of die correcting portion,, be easy in die assembling or glass moulding process, peel off so the coating intensity of plated film can be relatively poor, directly have influence on the yield of glass moulding processing procedure.
Obviously, aforesaid several present prior aries in use are not that accurate die external diameter precision can't be provided, and can't provide effective cured film to coat intensity exactly.In other words, in the prior art, the two is not taken into account accurate die external diameter precision and cured film coating intensity.
In view of this, the present invention promptly aims to provide a kind of method that can improve the sclerosis plated film precision of used die in the glass moulding processing procedure, can have good plated film precision and effective plated film simultaneously concurrently and coat intensity, to overcome the shortcoming of prior art.
