Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of mould of moulding optical element.
Background technology
Along with progress of science and technology, in computer, communication, consumption electronic products and various precision instrument and mould thereof, more and more higher to the degree that becomes more meticulous of each spare and accessory parts.For example: the aspheric surface plastic cement lens of extensive use on electronic product and precision optics, for satisfying light, thin, short, the little demand of product, it has become more and more littler; Meanwhile, in aspheric surface plastic cement lens forming process employed mould structure also along with dwindling.
At present, the mould that is used to make aspheric surface plastic cement lens is comparatively simple two template dies of structure normally, and two template dies generally include relative first minute mould and second fen mould.First fen mould and second fen mould respectively comprise a die holder, and a die that is installed in die holder, this die tool one mold pressing surface.When described first minute mould and second fen mould matched moulds, two relative die holders are by guide-localization element alignment location, form a die cavity by mold pressing surface between the two relative dies, for the material feeding moulding.After the moulding, first fen mould separated with second fen mould, can take the aspheric surface plastic cement lens of moulding away.
But, the thickness of the formed aspheric surface plastic cement of above-mentioned two template dies lens is determined by above-mentioned die cavity, in forming process, can't adjust the thickness of aspheric surface plastic cement lens, thereby need the different die of exploitation to make the aspheric surface plastic cement lens of different-thickness, making need long mold developing cycle.
Summary of the invention
In view of this, be provided at a kind of mould of moulding component thickness of in forming process, can adjusting in fact for necessary.
Below will a kind of mould that can adjust the moulding component thickness in forming process be described with embodiment.
This mould comprises first fen mould, second fen mould, first slide block and second slide block.This first fen mould and second fen mould have a land area respectively, and this land area contacts when matched moulds, and this first fen mould inwardly offers a host cavity from land area.This first slide block and second slide block are arranged in this host cavity and can slide relatively, this first slide block is provided with first die and goes into the son and the first adjustment element, this second slide block is provided with second die and goes into the son and the second adjustment element, this first slide block and second slide block slide in host cavity and can go into son and second die goes into to form die cavity between the son at this first die in mutual close mode, and this first is adjusted element and second adjust element and act on respectively that this first die is gone into son and this second die is gone into sub in order to adjust the size of this die cavity with this.
With respect to prior art, described first slide block, second slide block in described host cavity mutually near and go into son and this second die goes into to form die cavity between the son at this first die, in the element forming process, first adjust element and this second and adjust element and control this first die respectively and go into son and second die to go into son mobile adjusting the size of this die cavity by this, thereby can adjust the thickness of the profile member that will form.
