Description
Technical field
The utility model relates to the plant equipment field of optical disc production, relates more specifically to a kind of CD die arrangement that CD is carried out pressing mold.
Background technology
CD has been deep into people's routine work and various fields in life widely, because the widespread use of CD makes the research of field of optical discs is constantly deepened and expansion.Now, the CD of high record density can be produced more, when manufacturing has the CD of high record density, at first on a side of glass template, make with photoresist, and to its exposure and development, next the structural drawing that obtains wanting carries out nickel plating or silver-plated in the above, like this, original template has just created.Then, the structural drawing that is formed on the original template by transfer printing obtains stamper.This stamper is used as in order to form the pressing mold of predetermined pattern on the dish substrate.And for such CD, this stamper can be used as pressing mold, and in order to the depressed part of recording information signal, promptly the convex region can be formed on photic zone one side.On substrate, from pressing mold transfer printing structural drawing as stamper, and thereby the predetermined composition of formation.Stamper is transferred to predetermined structural drawing on the CD by the technology of pressing mold often.
As shown in Figure 1, in the scheme of the CD die arrangement 100 of prior art ' employing, after stamping technique is finished, only take the method for blowing during the demoulding.Will be with dynamic model 2 ' go up stamper 2a ' and quiet mould 3 ' go up CD 3a ' separate, promptly by air blowing interface 8 sound stampers 2 ' and CD 3 ' between add pressurized air, utilize air pressure with CD 3 ' blow off.Under the normal condition, this method can be finished the demoulding smoothly, but because the instability of pressurized air itself, glue viscosity and inotropic nonuniformity, the influence of the variation of ambient temperature and humidity and other various uncertain factors during process implementing, have after causing pressing mold to be finished the unsuccessful or gassing time of the demoulding to extend could demoulding success phenomenon occur, and the appearance of these phenomenons or influence yield rate perhaps influences the production cycle.Therefore, prior art CD die arrangement 100 ' shortcoming be: have after pressing mold is finished the unsuccessful or gassing time of the demoulding to extend could demoulding success phenomenon occur.Cause the reason of gassing time lengthening to be: the instability of pressurized air itself, glue viscosity and inotropic nonuniformity, the influence of factor such as the variation of ambient temperature and humidity and other various uncertainties during process implementing so, then is unfavorable for enhancing productivity and reducing production costs.Therefore need a kind of CD die arrangement of the fast demoulding that can enhance productivity, reduce production costs badly.
The utility model content
The purpose of this utility model provides a kind of CD die arrangement, described CD die arrangement can overcome occur after pressing mold is finished the unsuccessful or gassing time of the demoulding to extend could demoulding success phenomenon, can enhance productivity, reduce production costs.
To achieve these goals, the utility model provides a kind of CD die arrangement, be applicable to CD is carried out pressing mold, comprise quiet mould, dynamic model, following positioning boss, last positioning boss and lower spring, described quiet mould is horizontal positioned, described dynamic model be positioned at described quiet mould directly over, described quiet mould has following stitching surface, the described center of stitching surface down is recessed to form down cavity downwards, the described central authorities of cavity down protrude out down reference column, described positioning boss down is sheathed on the described reference column down versatilely, the upper end of described lower spring and described following positioning boss are inconsistent, the bottom of the lower end of described lower spring and described cavity down is inconsistent, described lower spring in the raw the time the outstanding described stitching surface down of described positioning boss down be used to pass the center pit of CD, described dynamic model is equiped with stamper over against the described end face of stitching surface down, described stamper and the described relative pressing district that forms of stitching surface down, described dynamic model upwards is recessed to form cavity over against the described center of the end face of stitching surface down, described go up cavity and described time cavity over against, the described positioning boss of going up protrudes out downwards from the described centre that goes up cavity, wherein, described upward positioning boss and described going up between the cavity are formed with the space, be provided with demoulding telescoping mechanism in the described space, described demoulding telescoping mechanism comprises upper spring and demoulding jacking block, fixedly connected with described bottom of going up cavity in the upper end of described upper spring, fixedly connected with described demoulding jacking block in the lower end of described upper spring, described upper spring is the outstanding described stamper of described demoulding jacking block in the raw the time.
Preferably, described space shape ringwise.Described space circular in configuration is provided with and just can makes described demoulding jacking block uniform top in knockout course take off the CD bonding with stamper.
Preferably, protrusion is equipped with the flexible contact mat that is flexible on the lower surface of described demoulding jacking block.So the purpose that is provided with is the good CD of better protection in the knockout course.
Preferably, also comprise screw, the described upper end of reference column down offers the screw that is meshed with described screw, described down positioning boss runs through along the center and offers the sliding eye with boss, be connected with described screw retention after described down reference column passes described sliding eye, it is inconsistent with described boss separably that the nut of described screw is positioned at the top of described boss.So setting then guarantee to implement down positioning boss can be in the pressing mold process to the described lower spring of lower compression, and the extreme higher position in the knockout course is by described screw retention.
Compared with prior art, because in the utility model CD CD die arrangement, described upward positioning boss and described going up between the cavity are formed with the space, be provided with demoulding telescoping mechanism in the described space, described demoulding telescoping mechanism comprises upper spring and demoulding jacking block, fixedlying connected with described bottom of going up cavity in the upper end of described upper spring, fixedlys connected with described demoulding jacking block in the lower end of described upper spring, described upper spring in the raw the time described demoulding jacking block give prominence to described stamper.Therefore, in knockout course, because described demoulding telescoping mechanism returns to state of nature from compressive state, therefore described demoulding jacking block then can back down over against the CD on the stamper of the end face installing of described stitching surface down originally fitting in described dynamic model, makes on CD and the described stamper to separate.
By following description also in conjunction with the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used to explain embodiment of the present utility model.
