Abstract
The utility model discloses a mould core capable of being detached and transformed on line for a three-layer co-extrusion cross-bonding line. The mould core capable of being detached and transformed on line for the three-layer co-extrusion cross-bonding line comprises a big mould core and a small mould core, wherein the small mould core is assembled by oppositely splicing two semicircular half mould cores and installing a locking ring at the tail portion in a sleeved mode, the assembled small mould core is installed in an inner hole of the big mould core in a sleeved mode, and a draw line extends out along the locking ring and an inner groove of the half mould cores into the inner hole of the big mould core. Through matching of the big mould core and the small mould core, the mould core capable of being detached and transformed on line for the three-layer co-extrusion cross-bonding line is capable of continuously producing products of adjacent standards without stop of a machine, thereby reducing waste. The small mould core can be detached on line, production of small standard is converted into production of large standard, the replacement process is simple to operate, and line cores are stable.
Description
Technical field:
The utility model relates to electric wire production equipment field, and specifically a kind of three-layer co-extruded cross-linking line is with dismantling online the conversion core rod.
Background technology:
In the crosslinked production of mesohigh, the direct crosslinking process of peroxide is generally adopted in countries in the world at present, realizes producing by catenary suspension type continuous vulcanization dry method chemical crosslinking production line.Its process is: utilize the three-layer co-extruded unit of extruding to finish extruding of conductor shield-insulating barrier-insulation screen, enter the sealing cross-linking tube that is full of high temperature, high-pressure inert gas continuous uniform and finish cross-linking process, then enter the cooling tube cooling.Because extrusion adopts three-layer co-extruded mode; if produce the crosslinked cable of different size; as not taking necessary measure; certainly will to shut down more mold exchange, cause waste of material, increase cost; during especially more at production specification, that length is shorter cable; can produce larger waste, also can because the core rod frequent affects product quality, cause economic loss.
Have at present on the basis that changes mold insert structure and proposed a kind of method of not shutting down replacing: the method core rod is two combinations; by also cap is also tight; after will touching core and take out by the long tube that links with core rod when changing specification; unclamp and cap change need touch behind the core and tight and cap, will touch core by long tube again and assemble.The deficiency that the method exists is: one, change the size of core rod, hinder between just affecting that core rod cooperates with former middle mould, cause the extrusion pressure conversion.Need readjust mould or carry out the correction of operating parameter, cause unnecessary trouble; Two, in Renewal process, can cause the shake of core, may cause core the problems such as off-centre, ring to occur.Also have and a kind ofly adopt large small mould core to cooperate the method that realizes not shutting down die change, but the method can only realize large specification core rod is converted to the small dimension core rod, have certain limitation.
The utility model content:
In order to overcome the defective of above technology, the purpose of this utility model has provided a kind of three-layer co-extruded cross-linking line with dismantling online the conversion core rod, by the processing to core rod, is not changing under the prerequisite that core rod is installed, carry out the up and down replacing of adjacent-specification core rod, realize serialization production.
The technical solution of the utility model is as follows:
The three-layer co-extruded cross-linking line is with dismantling online the conversion core rod, it is characterized in that: comprise small mould core and big mould core, described small mould core is incorporated in afterbody suit retaining ring by the relative assembly of two semicircular half core rods and is combined to form, the small mould core that is combined to form is set in the big mould core endoporus, draught line is arranged along passing to the endoporus of big mould core in retaining ring and the half module in-core groove.
Described three-layer co-extruded cross-linking line is with dismantling online the conversion core rod, it is characterized in that: described half core rod is cylindricality, have semicylindrical opening along the axis direction leading portion, back segment has the taper hole with semicylindrical opening UNICOM, the half module outer core is processed with boss, has groove along half module wire mandrel direction on the boss.
Described three-layer co-extruded cross-linking line is characterized in that with dismantling online the conversion core rod: described big mould core one end has endoporus with the cylinder of tapering along axis, endoporus by the shoulder hole of leading portion and with it the bellmouth orifice of UNICOM form.
Described three-layer co-extruded cross-linking line is characterized in that with dismantling online the conversion core rod: described retaining ring inwall is provided with the wire casing corresponding with groove.
Described three-layer co-extruded cross-linking line is characterized in that with dismantling online the conversion core rod: described draught line draws and passes the groove of half core rod to the bellmouth orifice of big mould core from the wire casing of retaining ring.
Described three-layer co-extruded cross-linking line is characterized in that with dismantling online the conversion core rod: the tapering of the bellmouth orifice of described big mould core and the taper hole of small mould core is 30 °～60 °.
Advantage of the present utility model is as follows:
1, by the cooperation of two core rods, realizes that not shutting down adjacent-specification produces continuously, cuts the waste.
2, small mould core can be removed online, realizes that small dimension is replaced by large specification production.
3, Renewal process is simple to operate, and core is stable.

The specific embodiment:
Referring to Fig. 1:
The three-layer co-extruded cross-linking line is with dismantling online the conversion core rod, comprise small mould core and big mould core 1, small mould core is incorporated in afterbody suit retaining ring 3 by the 2 relative assemblies of two semicircular half core rods and is combined to form, the small mould core that is combined to form is set in big mould core 1 endoporus, the length of small mould core matches with big mould core die orifice length or exceeds 1～2mm, draught line 4 is arranged along passing to the endoporus 5 of big mould core 2 in retaining ring 3 and half core rod, 2 inside grooves.
Retaining ring 3 is ring body structurc, and inwall is provided with the wire casing 3-1 corresponding with groove 2-4.
Draught line 4 draws and passes the groove 2-4 of half core rod 2 to the bellmouth orifice 5-2 of big mould core from the wire casing 3-1 of retaining ring.
The tapering of the bellmouth orifice 5-2 of big mould core 1 and the taper hole 2-2 of small mould core is 30 °～60 °.
Mode of operation: the utility model is positioned in the three-layer co-extruding machine head.When changing specification, utilize draught line 4 that small mould core is pulled out extruder head, split small mould core, take off two each and every one half core rods 2, then retaining ring 3 is placed on the alignment mould, finish large specification and change small dimension.Small dimension is changed large specification and is adopted similar operations.
