Abstract
The utility model belongs to the technical field of information storage technology, which relates to a DVD optical disk mould which is used in optical disk production devices. The utility model solves the problem that because of different structures between DVD optical disks and VCD optical disks, VCD optical disks which are produced by the original VCD optical disk production devices only use a single face glue film so that the VCD optical disks can not be processed into DVD optical disks. The DVD optical disk mould comprises a pattern mould 1, a master disk clamp 2, a first mirror surface 3 and a master disk 4, wherein the first mirror surface 3 is combined with the master disk clamp 2, the master disk 4 is arranged on the first mirror surface 3, the end part of the master disk clamp 2 is provided with a concave cavity 5, the distance h between the bottom part of the concave cavity 5 and the bottom surface of a pattern cavity of the pattern mould 1 ranges from 1 millimeter to 1.2 millimeters, and the distance h between an information surface 6 of the master disk 4 and the bottom surface of the pattern cavity of the pattern mould 1 ranges from 0.54 millimeter to 0.62 millimeter. Only the end part of the master disk clamp is provided with the concave cavity, and the structure of an original VCD optical disk production device is not changed; thereby, the utility model can be used for producing DVD optical disks, the binding technology of a glue film is saved and materials are also saved.
Description
Technical field
The utility model belongs to technical field of information storage, is a kind of DVD compact disc mold that is used for optical disc production apparatus.
Background technology
Existing DVD optical disc production apparatus and VCD optical disc production apparatus, different because of the DVD CD with the structure of VCD CD, cause the difference of device structure device.The VCD CD is to be made of annular film 10, as shown in fig. 1.Be provided with the information faces 11 of the information of having stored on one face, described information faces is provided with reflective membrane and diaphragm for the male and fomale(M﹠F) fixed according to digital signal on male and fomale(M﹠F).Because CD drive has structural requirement to CD, so the thickness of VCD CD is certain, generally at about 1.2 millimeters, the information faces on it also is certain to the surface distance of CD.So produce the VCD CD special VCD optical disc production apparatus is arranged.
The DVD CD is then different with the VCD CD, as shown in Figure 2.It comprises the annular film 10 of two 0.6 millimeters thick, and a film is provided with information faces 11 therein.After two films were combined with each other, information faces was in the centre position, and its thickness is fit to be placed on the DVD CD drive, generally at 1.2 millimeters.Because the structure of DVD CD is different with the structure of VCD CD, need special DVD optical disc production apparatus so produce the DVD CD.This production equipment will be made the plastic injection-moulded in two compact disc mold of film earlier, form two films that 0.6mm is thick, and one of them has information faces 11, be combined into a CD by smearing of complexity is gluing again.
And the VCD CD that original VCD optical disc production apparatus is produced only adopts the single face film, on a face of single face film, be provided with the information faces that matches with stamper, distance between this information faces and another face is because of the requirement of VCD CD drive than the DVD CD about a times, the distance generally at 1.0～1.2 millimeters, thereby cause original VCD optical disc production apparatus can not process the DVD CD.
The utility model content
The purpose of this utility model is to provide a kind of DVD compact disc mold that can utilize existing VCD optical disc production apparatus to produce the DVD CD.
For realizing the purpose of this utility model, described DVD compact disc mold comprises pattern, the stamper clamper, first minute surface that combines with the stamper clamper, be arranged on the stamper on first minute surface, be provided with cavity in described stamper clamper end, described cavity bottom is the thickness H of a DVD CD to the distance between the bottom surface of pattern die cavity, and the information faces of described stamper to the distance between the bottom surface of pattern die cavity is the thickness h of half DVD CD.
Owing to only be provided with cavity in the end of stamper clamper, the connection drive mechanism that has kept former VCD optical disc production apparatus is constant, integrated structure between the stamper and first minute surface is constant, just can on the VCD optical disc production apparatus, produce the DVD CD, not only saved two films have been carried out bonding production technology, and saved material more than original DVD CD.
Description of drawings
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of existing VCD CD.
Fig. 2 is the structural representation of existing DVD CD.
Fig. 3 is the DVD compact disc mold structural representation of the utility model VCD optical disc production apparatus.
Fig. 4 is the I portion enlarged drawing of Fig. 3.
The VCD CD that Fig. 5 produces for the DVD compact disc mold of the utility model VCD optical disc production apparatus.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model CD is described in further detail:
As shown in Fig. 3,4, DVD compact disc mold described in the utility model comprises pattern 1, stamper clamper 2, the first minute surfaces 3, stamper 4, cavity 5, information faces 6.
Described pattern 1 is made of second minute surface 7 and die cavity ring 8, is formed with a circular-shaped, concave cavity, is used to form a DVD CD.Stamper clamper 2 is cylindric, and edge part is provided with the card division 7 to outer lug in the top.After stamper 4 is placed on first minute surface 3, stamper clamper 2 to be inserted in the hole of first minute surface 3, the interior circular hole edge of stamper 4 can be caught in card division 7, makes stamper 4 fixing.At this moment, the distance H between cavity 5 bottoms to the bottom surface of pattern 1 die cavity is 1.2 millimeters, and the information faces 6 of stamper 4 to the distance h between the bottom surface of pattern 1 die cavity is 0.6 millimeter.Cavity 5 is annular, and diameter is 31.6mm.
When by the outside F direction of the suction hole vacuum attraction on first minute surface 3, just form injection moulding in the DVD mould, in die cavity, form the sheet laser disc of an annular, i.e. DVD CD, as shown in Figure 5.DVD CD edge in circular hole forms one to protruding annulus portion, the about 31.6mm of dome ring portion diameter on one side.This DVD CD than existing DVD CD save starting material near half.When the DVD CD stacked, annulus portion can also separate adjacent DVD CD, prevents surface abrasion.
Show original VCD optical disc production apparatus as long as the disk holder mould is made to change mould slightly through development test, just can produce the DVD CD, need not add new production equipment.Adopt the utility model DVD compact disc mold to produce the DVD CD, its manufacture craft is simple, will two film carry out bondingly, can reduce production costs greatly.
