Abstract
The utility model relates to a blank arranging and pressing die for optical fiber products, and aims at providing a blank arranging and pressing die for large-size optical fiber products, which completes arrangement and melting type pressing of blanks. The blank arranging and pressing die comprises a die body, the die body comprises an upper V-shaped groove and a lower V-shaped groove, the notches of which are opposite to each other, wherein the lower V-shaped groove is used as a lower die, the upper V-shaped groove is used as an upper die or an arranging block, a gland is arranged on the top of the upper die, baffle plates are arranged on the left outsides and the right outsides of the upper V-shaped groove and the lower V-shaped groove, the lower parts of the baffle plates are fixed with the lower V-shaped groove, the left side and the right side of the interior of the upper V-shaped groove and the lower V-shaped groove are respectively provided with a vertical side strip contacting with the upper V-shaped groove and the lower V-shaped groove, the upper V-shaped groove and the lower V-shaped groove and the two side strips form a hexagonal cavity, and stop blocks are arranged at two opened ends of the die body. The blank arranging and pressing die solves the problem of separate procedures of arranging and pressing of the existing die, and reduces the displacement error of filaments caused by movement of plates.
Description
Technical field
The utility model relates to fiber products and makes the field, is specially a kind of fiber products blank row pressure mould.
Background technology
Fiber optic imaging device by by certain regularly arranged composite filament through fusion pressure, draw or reverse, cold working forms.Wherein fusion pressure is the critical process that blank is made, and blank quality directly influences the final product quality of optical fibre device.
The quality of fiber products blank depend primarily on the single fiber silk scale error, arrangement positionerror and arrange moulding after relative displacement in the fusion pressure process, distortion that the more important thing is mould causes the decline of blank quality.It is yielding to be used for suppressing large-scale optical fiber blank mould with the optical fiber fusion pressure mould of pre-structure, and need row's board mold supporting with it, the making of blank is in row's template die the composite filament ordered arrangement to be become plate earlier, take out gently from row's template die and move into the fusion pressure mould, this process is finished by the grasping of staff.Along with the increasing of plate face, in moving process, be difficult to plate is held, because silk or the independent individual of this moment there is no adhesion during arrangement, in this process, very easily cause the displacement between the silk, cause the downgrade of fiber products blank.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of large-scale optical fiber product blank row pressure mould, and row's plate of base substrate, fusion pressure are all finished in this mould.
For solving above technical problem; a kind of large-scale optical fiber product of the utility model blank row pressure mould; comprise die ontology; described die ontology comprise notch relative on; following V-shaped groove; described V-shaped groove down is a counterdie; last V-shaped groove is patrix or row's plate; the patrix top is placed with gland; on; the left and right sides outer side of following V-shaped groove is provided with baffle plate; the baffle plate bottom is fixed with following V-shaped groove; on; following V-shaped groove inside each side is provided with one with last; the vertical side slat of following V-shaped groove contact, on; following two V-shaped grooves and two side slats form a hexagon cavity, also are provided with sprue at die ontology two opening ends.
During use, earlier the composite filament that draws repeatedly is broken into fixed length, the side slat of adjusting mould arrives appropriate position so that the hexagon cavity size of mould can satisfy the blank dimension requirement of moulding.The row's of placement plate is arranged in the fixed length composite filament in the mould in an orderly manner, requires to give much attention to the exactness of arrangement position between the silk in the alignment processes.After composite filament was arranged the body of having one's bosom filled with, the row's of unloading plate was placed patrix simultaneously on composite filament.Sprue is placed on the base plate, and die ontology is lifted in the space that base plate and sprue form, and the push-tight sprue is put into the hot pressing burner hearth with the mould that assembling is finished, at last by the program that is fit to is found time, temperature control, pressurization are finished blank compacting.
The outside of die ontology and two sprues is with lock sleeve.Because fusion pressure mould silk in pressing process can extend to the sprue direction, along with the increase of pressure is also increasing to the outside thrust of sprue generation, sprue very easily is out of shape when the blank of compacting large-scale optical fiber product, this also is the reason that causes blank quality to descend, and therefore, the place is provided with lock sleeve at plug, improved the structural strength of mould, reduce the distortion of mould, improved the work-ing life of mould, thereby improved the internal soundness of blank.
The row of the utility model mould, pressure are all finished in this mould, have overcome mould row, pressure separation in the past, have reduced the shift error that moving of plate caused silk.Increase lock sleeve and improved structural strength, reduced the distortion of mould, prolonged life cycle, finally improved the quality of product.And can be by adjusting the blank that the side slat position makes similar sizes.

Embodiment
A kind of large-scale optical fiber product blank row pressure mould described in the utility model, comprise die ontology, described die ontology comprise notch relative on, following V-shaped groove, described V-shaped groove down is a counterdie 1, last V-shaped groove is patrix 2 or row's plate 3, when suppressing, patrix 2 tops place gland 4, on, the left and right sides outer side of following V-shaped groove is provided with baffle plate 5, baffle plate 5 bottoms are fixed with following V-shaped groove, on, following V-shaped groove inside each side is provided with one with last, the vertical side slat 6 of following V-shaped groove contact, on, following two V-shaped grooves and two side slats 6 form a hexagon cavity, also are provided with sprue 8 at die ontology two opening ends.The outside that sprue 8 is placed on a base plate 7 mold bodies and two sprues 8 is with lock sleeve 9.
This practical technique adopts resistant to elevated temperatures material to make mould.The inner chamber basic size of its mould is tentatively formulated according to large-scale optical fiber final dimension consideration process redundancy and fusion pressure shrinkage.Determine the final size of inner chamber according to factors such as the specification of arranging composite filament, arrangement radicals.Requirement of strength when considering row, the space of pressing and compacting by inner cavity size is determined the size of each parts of mould and the cooperation between precision and each parts, thereby is finished Mould design, manufacturing, satisfies the blank of large-scale optical fiber product performance in order to making.As long as determined size, the silk footpath of large-scale optical fiber product, and aligning method all can be by calculating the scope of application of determining die size and mould.Satisfy the processing requirement of large-scale optical fiber product, overcome the disadvantage of traditional mould, improve the quality of blank blank.
