Can learn after according to Fig. 1, Fig. 2 moveable die 11 being described that moveable die 11 has possessed on movable plate with installing plate and die main body portion 12 of installing and the base plate 13 that is installed on die main body portion 12.And, be with bolting mirror board 14 in base plate 13 fronts.Base plate 13 and mirror board 14 respectively for have central opening decide the disc member of thickness of slab, 14 of mirror boards form the cooling ditch.The front of mirror board 14 has installs the swager 15 that duplicates shaping optic disc base board M1 signal face 41.On aforementioned base plate 13 and mirror board 14 central openings, then set interior all swager bearings 17 of thimble sleeve 16, support swager 15 inner peripheral portions.The peripheral part of mirror board 14 has then fixedly set in cavity C 1 and forms optic disc base board M1 outer peripheral face 45 and have the peripheral ring 18 of periphery swager bearing concurrently.
As shown in Figure 2, the peripheral ring 18 of this example is the annular component that possesses swager fixed part 19 and interior perimembranous 20.Swager fixed part 19 belongs to the circumferentia of the anti-fixed mould side that is arranged at peripheral ring 18, prevents to contact floating of swager 15 outer peripheral edges portion surfaces or swager 15 outer peripheral edges portions in order to support.Interior perimembranous 20 is to prolong towards fixed mould 31 sides, and some is that swager 15 surfaces are the direction of orthogonal, and is inclination at cavity C 1 outer circumferential side of angle A, to form the 1st gradient face 21 towards the hole enlargement of fixed mould side.Angle A with the 1st gradient face 21, on the periphery fitting portion 38 of aftermentioned fixed mould 31 mirror boards 34, moveable die 11 peripheral rings 18 can be embedded in when relatively moving the position, the scope do not block can be enlarged, and 3 ° of the value ranges that melting resin is difficult for immersing B at interval can be dwindled when being set at the compression melting resin.Moreover, preferably 2 ° and even 8 ° of this angle A.The 1st gradient face 21 when matched moulds, having concurrently fixed mould 31 mirror boards 34 periphery fitting portion 38, and the cavity that is opposed chimeric surface and forms optic disc base board M1 outer peripheral face 45 as shown in Figure 3 across 0.005～0.01mm gap B form face.And the border between aforementioned chimeric surface and the cavity formation face, when compression molding, can change because of peripheral ring 18 and mirror board 34 chimeric relative positions.Moreover on aforementioned the 1st gradient face 21 chimeric surfaces and fixed mould 31 mirror boards 34, the either party of periphery fitting portion 38 or both sides also can the section of forming shapes.
In addition, shown in Fig. 2 explanation, connect on swager 15 sides of peripheral ring 18 the 1st gradient face 21, then form toward swager 15 side cavity C 1 interior side-prominent periphery cyclic lug 22.Periphery cyclic lug 22 except the stationary plane 22a that is provided with fixed mould device some, slightly contact the 22b of protruding end portion on swager 15 surfaces, and towards the 2nd gradient face 22c of this 22b of protruding end portion hole enlargement, aforementioned the 2nd gradient face 22c also by interior perimembranous 20 the 1st gradient face 21 decide the arc surface 22d of radius of curvature with smooth and easy connection.Moreover, on the 1st gradient face 21 position E as shown in Figure 2, when cavity C 1 is finished compression, then be the position of cavity C 1 most peripheral, the diameter of cavity C 1 is defined as optic disc base board M1 outside dimension 120 ± 0.3mm, and the constriction when melting resin cooled off is set at and estimates size.Next, optic disc base board M1 is so long as belong to DVD usefulness, and the thickness of optic disc base board M1 is 0.6mm just so, and the thickness of cavity C 1 also is at 0.6mm, and the constriction when melting resin is cooled off is set at estimates size.
In addition, periphery cyclic lug 22 22b of protruding end portion, and aforementioned the 1st gradient face 21 position E between the projecting height F of swager 15 surface direction distances when being maximum, can on signal face 41, form the signal pothole, and become the limit positions of most peripheral on the specification, even and minimum of a value, also can set the scope of effective performance effect.Periphery cyclic lug 22 numerical value, being respectively the 22b of protruding end portion angle G is 30～60 °, aforementioned projecting height F is 0.2～1mm.In addition, aforementioned arc surface 22d radius of curvature is preferably in 0.1～0.8mm scope.Moreover periphery cyclic lug 22 is not must thing in the present invention.
Below will fixed mould 31 be described by Fig. 1, Fig. 2, fixed mould 31 has possessed the die main body portion 32 that is installed on fixed disk, the base plate 33 that is installed on die main body portion 32.In aforementioned base plate 33 fronts of moveable die 11 opposed faces, be mirror board 34 to be installed with bolt.Base plate 33 and mirror board 34 respectively have the disc-shaped component of thickness of slab that central opening is decided, and then form the cooling ditch on mirror board 34.On the central opening of aforementioned base plate 33 and mirror board 34, Central boss 35 or sprue bush 36 etc. have then been set.In addition, mirror board 34 surfaces (moveable die opposed faces) do not set molding press, and forms the cavity formation face 37 of optic disc base board M1 reading face 42.Moreover, when on mirror board 34 peripheries, forming the matched moulds cavity, between the peripheral ring 18 of moveable die 11, then form periphery fitting portion 38 chimeric surfaces that envelope is ended melting resin.The chimeric surface of periphery fitting portion 38, it is the same then to be same as peripheral ring 18 the 1st gradient face 21, presents the gradient face towards the hole enlargement of fixed disk side.
The cavity of the mirror board 34 on this example forms on the peripheral part of face 37, and then as shown in Figure 2, ring-shaped protrusion 39 is one with the planar portions 37a that cavity forms face 37.Ring-shaped protrusion 39 is by the chimeric surface 39a that belongs to periphery fitting portion 38 somes, and have the Fixed width width of cloth I of institute flat top surfaces 39b, and form from the arc surface 39c that the outstanding institute of planar portions 37a that cavity forms face 37 decides radius of curvature towards outer circumference end, aforementioned arc surface 39c then connects the planar portions 37a of cavity formation face 37.
Moreover ring-shaped protrusion 39 flat top surfaces 39b wide cut I of the present invention are 0.03mm to 0.08mm preferably, and the projecting height H of ring-shaped protrusion 39 is 0.05mm to 0.3mm preferably, but 0.10mm to 0.20mm is better.
Its reason is, be shaped shown in the test result just as Fig. 4 of change ring-shaped protrusion 39 sizes, the top wide cut I of ring-shaped protrusion 39 greater than 0.08mm after, can be because of the resin gassing on optic disc base board M1 peripheral part 43 shown in Figure 3 that uses.In addition, when the projecting height H of ring-shaped protrusion 39 is higher than 0.30mm, can be on peripheral part 43 gassing and become defective products.In addition, after flat top surfaces 39b wide cut I thickness is lower than 0.03mm, near melting resin pressure that can be when penetrate filling, and allow ring-shaped protrusion 39 tops lateral bending song outwardly, and may ring-shaped protrusion 39 chimeric surface 39a, and peripheral ring 18 the 1st gradient face 21 between the problem blocked.Moreover the top of ring-shaped protrusion 39 also can be uneven surface but smooth and easy outstanding R face.
In addition, the reason of the optimum size of the projecting height H of aforementioned ring-shaped protrusion 39 is that after the projecting height H of ring-shaped protrusion 39 was lower than 0.05mm, meeting formed burr 46 and fractures easily near reading face 42.In addition, when the projecting height H of ring-shaped protrusion 39 is higher than 0.3mm, except meeting generation magnetic disc substrate M1 from mould is bad, processing during mirror board 34 from a slice stainless steel must stay ring-shaped protrusion 39 and prolongs to grind and cut the time that processing and finished machined cavity form face 37 planar portions 37a.The radius of curvature of aforementioned flexure plane 39c is 0.3mm and even 0.6mm preferably, and its result then is 0.33mm and even 0.68mm for the base portion wide cut J of ring-shaped protrusion 39.In addition, the flexure plane 39c of ring-shaped protrusion 39 also can make up with the gradient face of constant hole enlargement or gradient face and flexure plane.Moreover the integral cavity that comprises the ring-shaped protrusion 39 of mirror board 34 forms on the face 37, also can be coated with antifrictions consumption material such as Ti n, DLC, WCC, CrN or electroplates, in case abrasions take place aforementioned ring-shaped protrusion 39, and can prolong 34 life-spans of mirror board.In addition, aforementioned ring-shaped protrusion 39 is the most outstanding on the mirror board 34 of fixed mould 31, therefore can see through to improve and adhere to the hardness of scar with protective ring shape jut 39.Moreover, also can only carry out aforementioned abrasion performance coating etc. at ring-shaped protrusion 39.
Manufacturing process, and the method for making of the CD D of applying optic disc base board M1 manufacturing of optic disc base board M1 of the present invention below will be described.Be not shown in graphic emission forming machine movable plate meeting forward drive, matched moulds fixed mould 31 forms the cavity C 1 that can change volume with moveable die 11, never indicates in the graphic ejecting device, sees through 36 pairs of aforementioned cavity C1 supplies of sprue bush melting resin.Next, can allow moveable die 11 advance more, with the melting resin in the compaction cavum C1.Next then carry out the melting resin cooling curing in the cavity C 1 again, in case just can die sinking moveable die 11 after fixing time through institute and take out optic disc base board M1.
As shown in Figure 3, optic disc base board M1 is by on the signal face 41 (comprising blanking signal face) of optic disc base board M1, and melting resin is injected gap between molding press 15 and the peripheral ring 18, and forms the burr 44 about length 0.02mm, thickness 0.01mm.In addition, optic disc base board M1 outer peripheral face 45, be by ring-shaped protrusion 39 chimeric surface 39a, and peripheral ring 18 in gap injection melting resin between the perimembranous 20, to form the burr 46 about projecting height 0.02mm, thickness 0.01mm.These burr 46 height can be lower than the reading face 42 of optic disc base board M1.And, can form reading face side periphery flexure plane 47 because of ring-shaped protrusion 39 arc surface 39C, though can be because of the flat top surfaces 39b of ring-shaped protrusion 39, and form clearance portion 48 between aforementioned reading face side periphery flexure plane 47 and the burr 46, but the 48 wide cut I of aforementioned gap portion on this example only have 0.07mm, the size of adding burr 46 thickness then is about 0.08mm, so optic disc base board M1 of this example, because of the interval between peripheral part 43 main parts and the burr 46 is comparatively narrow, so burr 46 frangibility more not.Moreover, by the size of additional spacer B on ring-shaped protrusion 39 base portion wide cut J, and allow optic disc base board M1 reading face 42 peripheral parts of regulation, form the wide cut K of thin part towards outer circumferential side, therefore as before narrow can allow more not frangibility of burr 46.In addition, the applicant is on the polycarbonate resin of shaping test material kind, and the result of constriction aforementioned gap portion 48 can't be at peripheral part 43 gassings of optic disc base board M1 shown in Figure 4.
The optic disc base board M1 that has been shaped can be transported to follow-up engineering, after the engineerings such as aluminium-vapour deposition through signal face 41, other optic disc base board M1 by identical or different mould formed thereby, be by adhesive agent 49 with the signal face 41 of fitting each other when being blanking signal face (comprise a side), produce applying disk D such as DVD as shown in Figure 3 again.Moreover, during applying optic disc base board M1, though adhesive agent 49 outward perimembranous 43 flow, also can be, and allow the part signal face 41 perimeter thicknesses attenuation of optic disc base board M1 because of peripheral ring 18 periphery cyclic lugs 22, therefore aforementioned adhesive agent 49 can not ooze out from outer peripheral face 45.In addition, the height of burr 46 is lower than non-duplicating face 42, owing to can form aforementioned burr 46 near the main part of peripheral part 43, even touch the burr 46 of the outer circumference end of applying CD D, its sense of touch is also come obviously unlike the tradition product.
Moreover this example is that molding press 15 and peripheral ring 18 are equipped on moveable die 11 mirror boards 14, and the example that is provided with that ring-shaped protrusion 39 is set on fixed mould 31 mirror boards 34 below will be described.But also can on the fixed mould mirror board, set molding press and peripheral ring, and on the mirror board of moveable die, ring-shaped protrusion is set.In addition, can not set molding press fully on the mirror board yet.
Optical disc substrate forming mould 51 on other example shown in Figure 5 below will be described.Fig. 5 embodiment is on fixed mould 52 mirror boards 53, sets the molding press 54 that forms optic disc base board M2 signal face, and sets periphery module 55 in mirror board 53 outer circumference end.In addition, at the peripheral ring 57 that does not indicate formed optic disc base board M2 peripheral part in the graphic die main body portion of moveable die 56, can be by not indicating graphic spring, and move towards the closing direction of die sinking.Next, mirror board 58 is embedded in the peripheral ring 57, and 58 of mirror boards are arranged to and can be moved on relative position aforementioned peripheral ring 57.Therefore perimembranous 59 and mirror board 58 periphery fitting portions 60 in the peripheral ring 57 only are opposed across a little interval.Next, aforementioned mirror board 58 cavitys form the peripheral part of face 61, are to form from this cavity that the tabular surface 61a of face 61 is integrally formed continuously to go out ring-shaped protrusion 62.In addition, perimembranous 59 aspects in the peripheral ring 57, then (fixed mould 52 sides) form periphery cyclic lug 63 near molding press 54.Moreover ring-shaped protrusion 62, and periphery cyclic lug 63 size and shapes etc. are because of being similar to the example Therefore, omited explanation shown in Fig. 1 grade.
51 of optical disc substrate forming moulds shown in Figure 5 are set at; when aforementioned moveable die 56 peripheral rings 57; during contact fixed mould 52 periphery modules 55, the interval that does not pour into melting resin that is spaced apart of aforementioned peripheral ring 57 and molding press 54 is to form the cavity C 2 that can change volume.Next, with melting resin penetrate be filled in cavity C 2 after, moveable die 56 is along with moving towards fixed mould 52, and shrinks the spring result between peripheral ring 57 and the die main body portion, allow peripheral ring 57 and mirror board 58 move relative position, and the melting resin in the compaction cavum C2.Moreover explanation is omitted because of slightly being same as the example shown in Fig. 1 etc. in aspects such as the place of formation burr and burr size.Moreover, embodiment illustrated in fig. 5, also molding press can be installed on moveable die, formed mirror board of periphery jut and peripheral ring are arranged at fixed mould, also can molding press be arranged on two side molds.
In addition,, be not confined to the invention described above example, also applicable to being familiar with this operator according to change that purport of the present invention applied though do not enumerate the present invention one by one; Though no matter this example DVD on the books could write, and all can be applicable to the shaping of other optic disc base boards such as CD, Blu-ray Disc CD.
