Description
Technical field
It is double-deck particularly with regard to a kind of extruder for being used for double-deck cable production the present invention relates to extrusion die field
Co-extruding mould.
Background technology
At present, existing extruder double-layer coextrusion mould has the following disadvantages：
1st, there is a stepped hole the original-pack machine current divider front ends of extruder co-extruder head φ 65, and the size of stepped hole is small
In the full-size of core rod, therefore when installing core rod, it is necessary to first penetration pipe is pulled out from head, on clamping to bench vice,
Core rod could be installed to the position matched with threading hole, then penetration pipe is attached to inside head again.I.e. the installation of core rod compared with
Complexity, inconvenient operation.
2nd, because a part of length of core rod will be wanted and die sleeve by stepped hole in the machine current dividers of φ 65, another part length
Match, form differential seat angle, therefore the length of core rod is longer, is unfavorable for the processing of core rod.
The content of the invention
The technical problems to be solved by the invention：There is mould installion complexity, inconvenient operation, core rod for prior art
It is oversize, not the problem of easy processing there is provided one kind it is reasonable in design, simple in construction, mould installion is simple to operate, difficulty of processing it is low squeeze
Go out machine double-layer coextrusion mould.
A kind of extruder double-layer coextrusion mould, including pair of lamina co-extruding machine head, the co-extruder head also include shunting
Device, penetration pipe and a core rod, the penetration pipe are arranged on the inner side of the current divider, and the core rod is arranged on the current divider
One end, it is characterised in that be coaxially arranged between the core rod and current divider one with the core rod be adapted core rod seat,
A projection being adapted with step in the current divider is provided with core rod seat, one end of the core rod seat is worn with described
Spool is connected, and the other end is connected with the core rod；One is additionally provided with one end of the co-extruder head is used to eject core rod
Ejection frock.
In a preferred embodiment of the invention, the core rod seat is combined into taper fit with matching somebody with somebody for core rod.
Due to using above-mentioned technical proposal, the beneficial effects of the invention are as follows：
1st, core rod seat one end is connected with penetration pipe, and other end is connected with core rod, must be drawn when solving mould installion
Go out penetration pipe could installation mold the problem of, make mould installion simple to operate, thus shortened operator's installation mold when
Between；
2nd, it is taper fit form original threaded connection reshaping formula, core rod just can torn open from being above mounted directly
When unloading, it can directly be ejected with frock, reduce the difficulty of processing of mould, so as to reduce the processing cost of mould；
3rd, mould material therefor is reduced, mold materials cost is reduced.
Brief description of the drawings
Fig. 1 is a kind of structural representation of extruder double-layer coextrusion mould of the present invention.
Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
A kind of extruder double-layer coextrusion mould shown in Figure 1, including pair of lamina co-extruding machine head 100, double-layer coextrusion machine
First 100 also include current divider 200, the core rod 400 of penetration pipe 300 and one, and penetration pipe 300 is arranged on the inner side of current divider 200, mould
Core 400 is arranged on one end of current divider 200.
A core rod seat 500 being adapted with core rod 200 is coaxially arranged between core rod 400 and current divider 200, in core rod
A projection 510 being adapted with step 210 in current divider 200, one end of core rod seat 500 and penetration pipe 200 are provided with seat 500
Connection, the other end is connected with core rod 400, and increase core rod seat 500 can reduce the dismounting difficulty of core rod 400.
An ejection frock 600 for being used to eject core rod 400 is additionally provided with one end of co-extruder head 100.
In the present embodiment, core rod seat 500 and core rod 400 be with being combined into taper fit, can be by using frock 600 is ejected
Core rod 400 is easily ejected.
Beneficial effects of the present invention：
1st, core rod seat one end is connected with penetration pipe, and other end is connected with core rod, must be drawn when solving mould installion
Go out penetration pipe could installation mold the problem of, make mould installion simple to operate, thus shortened operator's installation mold when
Between；
2nd, it is taper fit form original threaded connection reshaping formula, core rod just can torn open from being above mounted directly
When unloading, it can directly be ejected with frock, reduce the difficulty of processing of mould, so as to reduce the processing cost of mould；
3rd, mould material therefor is reduced, mold materials cost is reduced.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
