The PCT parcels mould 141 includes the second molding cavity, and the insulation parcel mould 151 includes the 3rd molding cavity, institute
State the second molding cavity and the 3rd molding cavity is respectively provided with deflector, molten condition is increased by the setting of the deflector
PTC and insulating materials rotary power, make the rotational agitation of fused solution more violent, while it is logical by feeding to reduce fused solution
Road enters the confusion that melt space produces flow direction.
The marginal portion of the discharging of stent 131 end face sets gap with the first annular boss 111, is first-class
Cavity, the PCT materials of the molten condition enter described second by second feeding-passage 17 through first flowing lumen
Melt space.The discharge end center of the stent 131 extends into second melt space and forms raised land, for the
One distributary division, the distance on the first distributary division inclined-plane to the second molding cavity inner surface are less than first flowing lumen
Gap size, make the PCT materials of the molten condition thinning by this set, be easy to uniformly heat, in favor of the melting
The further plasticizing of the PCT materials of state.
To realize the effect above, the distance on the first distributary division inclined-plane to the second molding cavity inner surface needs gradually
Diminish, therefore the first distributary division thickness h is set, first distributary division is traditionally arranged to be cone type.
Wherein, D1For basal diameter of first distributary division in the stent, D2Stretched into for first distributary division
The end face diameter of the PCT parcels mould, D3The interior circular diameter of mould feed end is wrapped up for the PCT；D4Mould is wrapped up for the PCT to go out
Expect the interior circular diameter at end；L is the distance of first flowing lumen；L is the length that the PCT wraps up mould.
The PCT parcel mould feed ends and discharge end inner circle difference in diameter are bigger, constant in the length of PCT parcel moulds
In the case of, illustrate that the PCT parcel mold cavities angle of inclination is bigger, the first distributary division both ends of the surface diameter is constant, described
The bevel inclination angle can of first distributary division is bigger, and the first distributary division thickness is bigger；First flowing lumen
The distance of distance is bigger, illustrates that the circulation area of first flowing lumen is bigger, the first distributary division thickness is bigger.
By the setting to the first distributary division thickness h, the setting to the first distributary division shape is realized, is made described
The PCT materials of molten condition are thinning, are easy to uniformly heat, in favor of the further plasticizing of the PCT materials of the molten condition.

Embodiment five
A kind of application method using the present invention includes step：
S1, debug and the co-extruding machine head is installed；
S2, two metal insides are actively released from the active paying out machine and the draw drum, be tensioned through the dancing wheel
After being heated with the heater, into the co-extruding machine head；
S3, the metal inside carry out parcel operation in the co-extruding machine head；
S4, the metal inside are completed after parcel operation again after Water Tank with Temp.-controlled cooling, by the draw-gear and
The take-up reel is kept well.
Wherein step S1 selects to meet manufacturing conditions and supporting specifically, the specification of the analysis heating cable to be made
The core rod support set 11, the inlet wire positioning module 12, the inner conductor layer module 13, the PTC layers module 14 and institute
State insulating barrier module 15.
Connecting for the inlet wire mould 121 and the opening of the positioning mould 122 is adjusted, debugs second helical gear
136 simultaneously and the adjacent braking parts 135 mated condition, by second helical gear 136 adjust to the adjacent braking
The transmission better position in portion 135, and position adjustments are carried out to first motor, ensure first helical gear and described second
Mating connection between helical gear 136, ensure the normal work of the inner conductor layer module 13.
The inner conductor layer module 13 is first fed into port from the core rod support set 11 and is attached to the core rod support set
In 11, and pass through the fixed positions such as pin or bolt, the space of guarantee first flowing lumen；It is fixed to complete the inner conductor layer
The inlet wire positioning module 12 is fixed in the core rod support set 11 after module 13, ensures first feeding-passage
16 with the circulation of the opening, while ensure the positioning mould 122 and described rotate being correspondingly arranged for mould 132.
The PCT is wrapped up into mould 141 to be attached in the core rod support set 11 from the core rod support set 11 port that discharges,
And realize the position that mould 141 is wrapped up the PCT in the core rod support set 11 by the way that the stock mould 142 is fixedly mounted on
Limit, power applied to first linkage portion 144 in outside, detect PCT parcel mould 141 whether can with normal rotation,
Avoid the damage of the second motor and the first gear group 191 described in when PCT parcel mould 141 is stuck to cause normal use.
Similarly install and test the insulation parcel mould 151 and the wire finishing die 152.
The position of the first gear group 191 and the second gear group 192 is adjusted, ensures the first gear group 191
With the normal drive connection of first linkage portion 144, the second gear group 192 and second linkage portion 154.
The compound module detected will be installed in the housing 2, ensure first feeding-passage 16, institute
State the connection of the second feeding-passage 17, the 3rd feeding-passage 18, and by the feeding assembly, the preceding gland, it is described after
Gland is fixed with the housing 2 installation, ensures that the plastic extruder connects with the feeding assembly respectively.
Step S3 specifically, the metal inside by the effect of the positioning mould 122 ensure the metal inside it
Between distance, entering in first melt space, caused by the rotation of first motor output shaft described first oblique
Pinion rotation, drive second helical gear 136 to rotate, so as to realize the adjacent rotation for rotating mould 132, make molten condition
The conductor material produce certain rotation, also there is a certain degree of rotation in the conductor material being wrapped on the metal inside
Turn, the conductor material is further shaping plasticized in the forming part 134 to be formed fine and close and combined tightly with the metal inside
Close inner conductor layer.
The metal inside with the inner conductor layer successively second melt space parcel PTC heaters layer,
Composite insulation layer is wrapped up in the 3rd melt space, finally completes all parcel operations in the wire finishing die 152.
Because PCT parcel moulds 141 and the insulation parcel mould 151 all produce rotation, and in the work of the deflector
Under, the PCT materials and the insulating materials under molten condition produce more violent rotation, make to be wrapped in the metal
Also there is a certain degree of rotation in melted material on inner core, the melted material further the stock mould 142, it is described go out
It is shaping plasticized in line mould 152 to form PTC heaters layer fine and close and compact with a upper integument, composite insulation layer.
The rotation direction of the PCT parcel moulds 141 and the insulation parcel mould 151 is on the contrary, in second melt space
When having wrapped up the metal insides of PTC layers and having entered in the 3rd melt space, the melting insulation inside the 3rd melt space
Material can produce the rotation opposite with PTC layers, make fixation therebetween even closer, lift the stability and safety of cable
