The utility model discloses increase mobilizable supports pipe in the mold core, stretch out the die sleeve with the pipe before disconnected fine, make the material extrude along the pipe, avoid the material suck -back to the mold core in, reduced and traded the fine time, improve production efficiency, the reduction waste, consequently, can avoid giving birth to and produce the in -process, the material suck -back is to the mold core is interior, eccentric is difficult to adjust, intermode apart from the difficult scheduling problem of controlling to improved production efficiency, the cost is reduced is extravagant.
Description
Technical field
This utility model relates to the technical field that optical cable produces, and is specifically related to a kind of Novel extrusion type mould。
Background technology
Along with the development of optical communication network, for meeting the market requirement, to the challenge that the proposition of inside cable production technology is very big, for meeting properties of product requirement in inside cable production process, mould plays very important effect。
In order to meet properties of product requirement, in current industry, widely used extrusion die includes die sleeve and core rod, as it is shown in figure 1, be provided with endoporus 101 in core rod 1, is used for arranging optical fiber, and core rod 1 front end is taper, and die sleeve 2 surrounds taper, matches with core rod 1 front end。This extrusion die is when producing, owing to mould inner pressure is excessive when changing optical fiber, material sucks mould along the endoporus 101 of core rod 1, owing to material is by mould inner reversible cycle when wearing fibre, and fiber strength is on the low side, normal production cannot be penetrated, it is necessary to just can proceed normal production after mould is pulled down cleaning, affect production efficiency。When assembling due to this extrusion die, core rod 1 contracts inside die sleeve 2, it is impossible to carry out core shift adjustment, and after product rolls off the production line, percent defective substantially increases。This extrusion die in die assembly process owing to core rod 1 does not extend out die sleeve 2, be only capable of when adjusting core rod 1 with die sleeve 2 distance by frequently adjust intermode from, control the pressure of material extrusion in mould, it is ensured that properties of product。
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of Novel extrusion type mould。
In order to achieve the above object, the technical solution of the utility model is: a kind of Novel extrusion type mould, including core rod and die sleeve, described die core back end is provided with support, support conduit it is provided with in the endoporus of support and core rod, supporting slides between conduit and support, core rod is arranged, and supports and is provided with optic fibre hole in the middle part of conduit；Described back-end support is provided with the first limited block, and the endoporus front end of core rod is provided with the second limited block。
Described support catheter proximal end is provided with wears fine pipe, supports rear end of conduit and is provided with tail pipe, wear fine pipe, tail pipe external diameter all thin than supporting in the middle part of conduit。
The endoporus front end of described core rod is taper, and the support conduit wearing fine pipe rear end is taper。
Described wear length is die sleeve 2/3rds of fine pipe。
This utility model increases in core rod and movably supports conduit, before disconnected fibre, conduit is stretched out die sleeve, makes material extrude along conduit, it is to avoid material suck-back, in core rod, decreases and changes the fine time, improve production efficiency, reduce waste；It can thus be avoided raw in product process, material suck-back is interior to core rod, core shift is difficult to adjustment, intermode from problems such as difficulty controls, thus improve production efficiency, reduces cost waste。

Detailed description of the invention
This utility model is specifically described below by drawings and Examples。
A kind of Novel extrusion type mould, as shown in Figures 2 and 3, including core rod 1 and die sleeve 2, described core rod 1 somewhat rear end is provided with support 4, and support 4 is fixed on core rod 1。The middle part of support 4 is hollow, and this hollow parallel with the endoporus 101 of core rod 2 communicates。Being provided with support conduit 3 in the endoporus 101 of support 4 and core rod 1, supporting slides between conduit 3 and support 4, core rod 1 is arranged。Therefore, support conduit 3 to move in support 4 and core rod 1。Supporting and be provided with optic fibre hole 301 in the middle part of conduit 3, optic fibre hole 301 is transverse in the center of whole support conduit 3, and optic fibre hole 301 is used for arranging fiber cores。
Support 4 rear end is provided with the first limited block 5, and endoporus 101 front end of core rod 1 is provided with the second limited block 6。Support conduit 3 front end to be provided with and wears fine pipe 302, support conduit 3 rear end and be provided with tail pipe 303, wear fine pipe 302, tail pipe 303 external diameter all thin than the middle part supporting conduit 3。The internal diameter support in the middle part of conduit 3, wearing fine pipe 302 is identical。In supporting conduit 3 moving process, conveniently wear fine pipe 302, tail pipe 303 and carry out spacing with first limited block the 5, second limited block 6 to supporting conduit 3 respectively。Endoporus 101 front end of core rod 1 is taper, and the support conduit 3 wearing fine pipe 302 rear end is taper, matches with endoporus 101, conveniently wears fine pipe 302 and forward extends out。Die sleeve 2 is upper and lower two parts, and its front group is tapered, and this tapered planar is paralleled with the taper surface of core rod 1, facilitates core rod 1 and the die sleeve 2 extruding to material。Wear length is die sleeve 2 2/3rds of fine pipe 302, and when supporting conduit 3 and encountering core rod 1, die sleeve 2 is not stretched out in the front end wearing fine pipe 302。
During die assembly, support conduit 3 is moved to the second limited block 6, by controlling the distance between core rod 1 and die sleeve 2 during assembling, control intermode from ensureing that in mould, material pressure is stable。When producing, when support conduit 3 is moved to the first limited block 5, correct concordant with the front end of core rod 1 before supporting conduit 3, it is ensured that the extruding form of mould。
During due to assembling, the support conduit 3 in core rod 1 stretches out die sleeve 2, and when can ensure to produce according to concentricity between core rod 1 and die sleeve 2, the uniformity of sheath wall thickness, enhances product performance, reduce consumption, improving production efficiency。
In core rod 1, add moveable support conduit 3, before disconnected fibre, conduit is stretched out die sleeve 2, make material extrude along conduit, it is to avoid material suck-back, in core rod 2, decreases and changes the fine time, improve production efficiency, reduce and waste。
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should be encompassed within protection domain of the present utility model。
