Abstract
The utility model provides a plastic-material extruder head mold for an optical cable. The plastic-material extruder head mold comprises an extruder head and a mold core, wherein the extruder head is in a concave-round cavity shape, and the center of the extruder head is provided with a through hole; a flow uniformizer is arranged in the concave-round cavity of the extruder head, is round and is provided with a chute; a flange edge is arranged at the periphery of one end of the flow uniformizer, and is fixedly connected with the extruder head by fasteners; the mold core is sheathed in the uniformizer; one end of the mold core is connected with the bottom part of the concave-round cavity, and the other end of the mold core is fixedly connected with a mold sleeve by a positioning pin; the chute is arranged between the positioning pin and the mold sleeve; and an outer sleeve is arranged at the end of a wire outlet of the mold sleeve. The plastic-material extruder head mold provided by the utility model has the advantages that the stroke is greatly shortened, the mold penetrating operation of optical fiber is convenient, the internal space is expanded, impurities can fall outside a mold opening naturally and the phenomenon of fiber breaking or attenuation increase is prevented.
Description
Technical field
The utility model relates to a kind of mould, particularly optical cable plastic rubber material extruder head mould.
Background technology
Fast development along with the communication technology, Fiber to the home has at present come into huge numbers of families, well-known realize that Fiber to the home and be unable to do without the butterfly leading in cable, this just makes that the demand of butterfly leading in cable is increasing, the production capacity of traditional mode of production butterfly leading in cable does not satisfy the market demand far away, because there are a lot of drawbacks in the mould of traditional mode of production butterfly leading in cable, restricted the efficient of producing, and the product quality of producing is not high.Be former head and mould structure schematic diagram as Fig. 1, head 3 is roomy, current equalizer 2 external diameters are little and long, thereby the core rod 1 of joining is also very long, core rod 1 endoporus is very little and quite dark, when reinforcement passes from core rod 1, can cause impurity on the reinforcement core rod central authorities that drop to block the optical fiber entrance, make fibercuts, and cause transmission attenuation to increase.
The utility model content
Technical problem to be solved in the utility model is, a kind of extrusion die that has improved is provided, shorten the extrusion die stroke, enlarge the inner space, can make impurity drop to outside the die orifice naturally, in the optical cable production process, do not have because of the stifled mould of impurity, prevent from causing disconnected fibre or decay to increase phenomenon and take place, and make things convenient for optical fiber to wear mould greatly.
At above-mentioned technical problem, the technical scheme that the utility model is taked is, optical cable plastic rubber material extruder head mould, comprise head and core rod, one side of head is provided with charging aperture, charging aperture connects the extrusion molding main frame, it is characterized in that, head is spill circle nest shape and the center is provided with through hole, in the head spill circle nest current equalizer is installed, current equalizer is annular and is provided with hopper that current equalizer one end periphery is provided with flange, the flange of current equalizer is fixedlyed connected with head by securing member, be set with core rod in the current equalizer, an end of core rod is connected with head spill circle nest bottom, and the other end is fixedlyed connected with die sleeve by alignment pin, be provided with hopper between alignment pin and die sleeve, the line outlet end of die sleeve is equipped with overcoat.
Advantage of the present utility model is, by to mould appropriate design and improvement, reduced optical fiber is subjected to external force by mould time the extruding, make the cavity pressure balance, the frosting of extruding is smooth, smooth, suitable shortening mold stroke, make things convenient for the modulo operation of wearing of optical fiber, improved production efficiency and product quality greatly.
Description of drawings
Fig. 1 is the former extrusion die structural representation before improving.
Fig. 2 is structural profile schematic diagram of the present utility model.
Among the figure: 1. core rod, 2. current equalizer, 3. head, 4. securing member, 5. overcoat, 6. die sleeve, 7. alignment pin, 8. hopper.
The specific embodiment
Now the utility model is described in further detail by reference to the accompanying drawings, referring to Fig. 2, optical cable plastic rubber material extruder head mould, comprise head 3 and core rod 1, one side of head 3 is provided with charging aperture, charging aperture connects the extrusion molding main frame, it is characterized in that, head 3 is spill circle nest shape and the center is provided with through hole, in the head 3 spills circle nest current equalizer 2 is installed, current equalizer 2 is for annular and be provided with hopper 8, and current equalizer 2 one end peripheries are provided with flange, the flange of current equalizer 2 is fixedlyed connected with head 1 by securing member 4, be set with core rod 1 in the current equalizer 2, an end of core rod 1 is connected with head 3 spills circle nest bottom, and the other end is fixedlyed connected with die sleeve 6 by alignment pin 7,6 of alignment pin 7 and die sleeves are provided with hopper 8, and the line outlet end of die sleeve 6 is equipped with overcoat 5.
Extrusion die of the present utility model adopts high strength, high temperature resistant, corrosion-resistant and wear-resisting steel alloy, become sizing material after plastics are by the extruding machine heating, extruding flows into current equalizer 2, behind current equalizer 2 counterpressures, flow in core rod 1 and die sleeve 6 gaps, be molded into finished product by die orifice at last.Anti-wear performance is good in the mould, makes the runner of sizing material in extrusion unobstructed, and frosting is smooth, inner no bubble and sand holes.
Extrusion die of the present utility model can be produced all size butterfly leading in cable as series of products such as GJXH, GJXFH, GJYXH, GJYXFH, GJXV, GJXFV, GJYXV, GJYXFV.For example produce GJXH type butterfly leading in cable, earlier with reinforcement and optical fiber core rod 1, plastics become sizing material after heating by extruding machine, extruding flows into current equalizer 2, by behind current equalizer 2 counterpressures, flow in the gap of core rod 1 and die sleeve 6 again, extrude finished product by the die orifice moulding in the die sleeve 6 at last.
