The invention discloses a kind of extruder double-layer coextrusion molds, including pair of lamina co-extruding machine head, co-extruder head further includes current divider, penetration pipe and a mold core, the inside of current divider is arranged in penetration pipe, one end of current divider is arranged in mold core, and a mold core seat being adapted with mold core is coaxially arranged between mold core and current divider, a convex block compatible with step in current divider is provided on mold core seat, one end of mold core seat is connect with penetration pipe, and the other end is connect with mold core；One is additionally provided with for ejecting the ejection tooling of mold core in one end of co-extruder head, and the present invention solves the problems, such as that penetration pipe ability installation mold must be pulled out when mold installation, keeps mold installation easy to operate, to shorten the time of operator's installation mold；Mold core can be mounted directly from front, in disassembly, directly ejected with tooling, reduced the difficulty of processing of mold, to reduce the processing cost of mold；Mold material therefor is reduced, mold materials cost is reduced.
Description
Technical field
The present invention relates to extrusion die fields, double-deck particularly with regard to a kind of extruder for the production of the double-deck cable
Co-extruding mould.
Background technique
Currently, existing extruder double-layer coextrusion mold has the disadvantage in that
1, there is a stepped hole in the original-pack 65 machine current divider front end extruder co-extruder head φ, and the size of stepped hole is small
In the full-size of mold core, therefore when installing mold core, need first to pull out penetration pipe from head, on clamping to bench vice,
Mold core could be installed to the position to match with threading hole, then penetration pipe is attached to inside head again.I.e. the installation of mold core compared with
Complexity, it is inconvenient for operation.
2, because a part of length of mold core will be by stepped hole in 65 machine current divider of φ, another part length is wanted and die sleeve
Match, forms differential seat angle, therefore the length of mold core is longer, is unfavorable for the processing of mold core.
Summary of the invention
The technical problems to be solved by the invention: for the prior art, there are molds to install complicated, inconvenient for operation, mold core
Too long, not easy to be processed problem, provide it is a kind of design rationally, structure it is simple, mold installation it is easy to operate, difficulty of processing it is low squeeze
Machine double-layer coextrusion mold out.
A kind of extruder double-layer coextrusion mold, including pair of lamina co-extruding machine head, the co-extruder head further include shunting
The inside of the current divider is arranged in device, penetration pipe and a mold core, the penetration pipe, and the mold core is arranged in the current divider
One end, which is characterized in that be coaxially arranged between the mold core and current divider one with the mold core be adapted mold core seat,
A convex block compatible with step in the current divider is provided on the mold core seat, one end of the mold core seat is worn with described
Spool connection, the other end are connect with the mold core；One is additionally provided with for ejecting mold core in one end of the co-extruder head
Ejection tooling.
In a preferred embodiment of the invention, the mold core seat and matching for mold core are combined into taper fit.
Due to the adoption of the above technical scheme, the beneficial effects of the present invention are:
1, mold core seat one end is connected with penetration pipe, and other end is connected with mold core, must draw when solving mold installation
Out penetration pipe could installation mold the problem of, make mold installation it is easy to operate, thus shortened operator's installation mold when
Between；
It 2, is taper fit form original threaded connection reshaping formula, mold core can be mounted directly from front, tear open
When unloading, it can directly be ejected with tooling, reduce the difficulty of processing of mold, to reduce the processing cost of mold；
3, reduce mold material therefor, reduce mold materials cost.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of extruder double-layer coextrusion mold of the invention.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
A kind of extruder double-layer coextrusion mold shown in Figure 1, including pair of lamina co-extruding machine head 100, double-layer coextrusion machine
First 100 further include that the inside of current divider 200, mould is arranged in current divider 200, penetration pipe 300 and a mold core 400, penetration pipe 300
One end of current divider 200 is arranged in core 400.
A mold core seat 500 being adapted with mold core 200 is coaxially arranged between mold core 400 and current divider 200, in mold core
A convex block 510 compatible with step 210 in current divider 200, one end of mold core seat 500 and penetration pipe 200 are provided on seat 500
Connection, the other end are connect with mold core 400, and the dismounting difficulty of mold core 400 can be reduced by increasing mold core seat 500.
One is additionally provided with for ejecting the ejection tooling 600 of mold core 400 in one end of co-extruder head 100.
In the present embodiment, mold core seat 500 and matching for mold core 400 are combined into taper fit, can be incited somebody to action using ejection tooling 600
Mold core 400 easily ejects.
Beneficial effects of the present invention:
1, mold core seat one end is connected with penetration pipe, and other end is connected with mold core, must draw when solving mold installation
Out penetration pipe could installation mold the problem of, make mold installation it is easy to operate, thus shortened operator's installation mold when
Between；
It 2, is taper fit form original threaded connection reshaping formula, mold core can be mounted directly from front, tear open
When unloading, it can directly be ejected with tooling, reduce the difficulty of processing of mold, to reduce the processing cost of mold；
3, reduce mold material therefor, reduce mold materials cost.
The basic principles, main features and advantages of the present invention have 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 above embodiments and description only describe this
The principle of invention, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and together
Equal objects define.
