Moulding, there is the operation of conversion body, mould in integrated artistic, production process is dangerous, and product quality cannot ensure；Application number
For a kind of 2015208177550 utility model patent " Three-layer co-extrusion mold ", pass through internal layer spiral chute and middle helical layer
Chute carries out two layers of co-extrusion, is carried out subsequently into sprue three-layer co-extruded.Although this kind of scheme can form preferably adhesion,
Meet needed for each layer co-extrusion, but complicated, need often adjustment core shift degree during production, technique is cumbersome, is not suitable for longevity
Order the production requirement of double-insulated cable.
Therefore, there is an urgent need to develop one kind both to can guarantee that product quality, and can raising production efficiency exempts from tuningout core one
The insulating exruded mould of secondary co-extrusion.
Utility model content
The purpose of this utility model is to solve low production efficiency present in above-mentioned prior art, product quality cannot
Ensure, the problems such as core shift problem easily occurs in product, there is provided a kind of cable is with exempting from co-extruding mould of tuningout core insulation.
To achieve the above object, the utility model provides following technical scheme：
A kind of cable is with exempting from co-extruding mould of tuningout core double hyer insulation, including core rod and die sleeve, it is characterised in that：It is described
Interior insulation runner is provided between core rod and die sleeve, die sleeve lateral wall is provided with external insulation runner；The bottom of the die sleeve is provided with out
Material mouth, the outside of die sleeve bottom are provided with the annulus of a circle evagination, several apertures are provided with not on the upper surface of the annulus of protrusion
Same circular hole.
Preferably, in some circular holes, minimum-value aperture side close to external insulation material charging aperture, maximum diameter of hole side away from
Charging aperture from external insulation material is farthest.The size in circular hole aperture is to be used to adjust by being obtained after repeated processing experiment Innovatation
The optimum size of discharge pressure balance when section insulating materials enters this circle of annulus through external insulation runner.
Preferably, the angle of the outer wall of the core rod and die sleeve inwall is 30 degree so that in first layer insulating materials warp
Certain pressure can be kept during insulation runner extrusion.
Preferably, the centre of the core rod is provided with mold core cavities.
Compared with prior art, the beneficial effects of the utility model are：
A kind of cable provided by the utility model is with co-extruding mould of tuningout core insulation is exempted from, by being added on the outside of die sleeve
External insulation runner, the interior insulation runner between die sleeve and core rod forms double-layer channel, so as to produce being total to for double hyer insulation material
Squeeze.The insulating materials of melting is distributed by being arranged on the annulus of die sleeve exterior bottom equally distributed circular hole again, by not
Discharge pressure balance is adjusted with the aperture of size so that close structure between two layers, thickness is uniform, and surface is smooth, uses the longevity
Life length；The uniform non-eccentric of co-extruding mould discharging, so as to eliminate the core shift adjusting process in production process, work effect was both improved
Rate, it in turn ensure that product quality.
In addition, the utility model Method And Principle is reliable, step is simple, has very extensive application prospect.
As can be seen here, compared with prior art, operating procedure is reduced the utility model, and quality has reliable guarantee, production
Efficiency high, there is substantive distinguishing features and progress, its beneficial effect implemented is also obvious.

In the present embodiment, the angle of the outer wall of the core rod 2 and the inwall of die sleeve 1 is 30 degree so that first layer insulation material
Material can keep certain pressure when being extruded through interior insulation runner 3.
A kind of cable provided by the utility model is with co-extruding mould of tuningout core insulation is exempted from, by adding in the outside of die sleeve 1
If the interior insulation runner 3 between external insulation runner 4, with die sleeve 1 and core rod 2 forms double-layer channel, so as to produce double hyer insulation material
The co-extrusion of material.Again the insulation material of melting is distributed by being arranged on the annulus 5 of the exterior bottom of die sleeve 1 equally distributed circular hole 6
Material, balanced by different size of aperture to adjust discharge pressure so that close structure between two layers, surface is smooth, and thickness is equal
It is even, service life length；The uniform non-eccentric of co-extruding mould discharging, so as to eliminate the core shift adjusting process in production process, was both carried
High operating efficiency, in turn ensure that product quality, reduces operating procedure, production efficiency is high.
It is described above, only it is preferred embodiment of the present utility model, any formal limit is not done to the utility model
System, it is all that all any modification, equivalent and improvement etc. are done within the spirit and principles of the utility model, it should be included in this reality
Within new protection domain.
