Description
Technical field
The present invention relates to a kind of mould, and in particular to a kind of optics LED support die.
Background technology
In recent years there is a kind of optics LED support, be used primarily in touch-screen mobile phone and panel computer.Such as presently most flow process
IPHONE and IPAD series of products just employ such support.The glue position of this support has stand frame area larger, glue position section
The characteristics of product is little.So big and thin product but has profile maximum deformation quantity within 0.3mm and product is all local 10 times
Magnifier detection does not allow the requirement of burr.The big glue amount of product is little, and the pressure loss is big during injection, it is more difficult to fill；Pressure is little cannot
Filling, pressure is susceptible to stress deformation and product burr again greatly；Because product is elongated, very thin flat thimble can only be adopted to eject,
There can not be burr to produce on all flat thimbles and PL.Due to requiring without product offset, without burr, therefore the exploitation of such product has
Very big difficulty.
This optics LED support is generally used on the electronic product of high-tech content, there is that order volume is huge, the construction cycle
Very short the characteristics of, because existing mold assembly parts are not reached without product offset, the requirement without burr, this causes all multi-vendor face
Not only order volume of being envious of but also the awkward condition of indefinite construction cycle is done.
