Abstract
The utility model discloses a kind of DVD punching die device.A kind of DVD punching die device, include the first mould and the second mould, and both is paired.The borders of each mould size of die cavity, die cavity refers to the space between two moulds.A mould is provided with a pressing mold wherein, and pressing mold and die cavity are all annular.When closing with the first mould of press mold and the second mould, the distance of stamper surface border and die cavity is 1 to 100 microns, is less than the distance between the place of outer distance boundary 2 millimeters and press mold.This with novel beneficial effect is: can prevent optical data carrier DVD from occurring the phenomenon of edge than thick middle in process of production.
Description
Technical field
The utility model relates to a kind of punching die device, and particularly one is applicable to DVD punching die device.
Background technology
In order to store more information in unit are, the optical data carriers such as DVD, CD require higher precision usually.But the phenomenon that the edge that usually there will be the optical data carriers such as DVD, CD aborning wants center thick than center, this just will have impact on the precision of the optical data carriers such as DVD, CD.
Summary of the invention
The purpose of this utility model is to provide a kind of DVD punching die device, can prevent optical data carrier DVD from occurring the phenomenon of edge than thick middle in process of production.
For achieving the above object, the utility model adopts following technical scheme:
A DVD punching die device, comprising: the first mould and the second mould, and both are paired.The borders of each mould size of die cavity, die cavity refers to the space between two moulds.A mould is provided with a pressing mold wherein, and pressing mold and die cavity are all annular.When closing with two the first moulds of press mold and the second mould, the distance on stamper surface and die cavity border is 1 to 100 microns, is less than the distance between the place of rang ring external boundary 2 millimeters and press mold.
Preferably, a mould is provided with an air exhaust loop wherein, and air exhaust loop is positioned at the outward flange of mould, and irreplaceable.
Preferably, stamper mould is for the production of disc-shaped data carrier.Pressing mold includes with an outer peripheral disk portions, and the thickness at its edge is about 1 to 100 micron, and its thickness is greater than the place at distance 2 millimeters, edge.
Preferably, the thickness at edge approximately differs 10 microns with distance 2 millimeters, the edge thickness located.
Preferably, manufacture disc-shaped data carriers DVD and comprise the first mould with data and the second mould with data, data are present on mould that face inwardly.
Preferably, punching die device also comprises an injection molding apparatus.
The beneficial effects of the utility model are: can prevent optical data carrier DVD from occurring the phenomenon of edge than thick middle in process of production.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of DVD punching die device.
Fig. 2 is the enlarged diagram of the part A of Fig. 1.
In figure: the core 3 of the first mould 1, second mould 2, second mould, air exhaust loop 4, pressing mold 5, die cavity 6, thickeies 7, tangent line 8, edge is to the distance a of pressing mold, and distance 2 millimeters, edge place is to the distance b of pressing mold, distance 2 millimeters, edge c.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the schematic diagram of DVD punching die device.Comprise the first mould 1 and the second mould 2.The second described mould 2 is made up of core 3 and air exhaust loop 4.Described air exhaust loop 4 is irreplaceable, the first described mould, with pressing mold 5 on 1.Die cavity 6 refers to the region that the front of the core 3 of described pressing mold 5, second mould and air exhaust loop 4 define.Plastics can be injected in described die cavity 6.
Fig. 2 is the enlarged diagram of the part A of Fig. 1.Thicken 7 to be offset by the front of tangent line 8 to the second mould 2.Can be deepened understanding of the present utility model by Fig. 2.
Owing to being provided with described thickening 7, making pressing mold 5 have slight radian connecing antermarginal position, had small gap at described edge between the distance a of pressing mold and the distance b locating pressing mold apart from 2 millimeters, edge.Gap in actual production between two is generally 10 microns.
Owing to having added described thickening 7, described edge has been made to locate to have small gap between the distance b of pressing mold to the distance a of pressing mold and distance 2 millimeters, edge.This just can prevent optical data carrier from occurring the phenomenon of edge than thick middle in process of production.Thus ensure that the precision that the optical data carriers such as DVD arrive, thus can make it in unit are, record more data.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
