Description
Technical field
The present invention relates to cable sheath extrusion molding technology, in particular to a kind of mould structure being applicable to cable sheath extrusion molding.
Background technology
Sheath extruded mould of the prior art, as Authorization Notice No. be CN201435271Y utility model patent disclosed in a kind of cable sheath extrusion die, comprise mould cover and mould core, mould core be placed on mould overlap in; But the jacket inner wall that this kind of die production goes out is more smooth so that electric wire easily slides in sheath, thus the electric property making cable is unstable.
Of the prior art.
Summary of the invention
It is an object of the invention to provide a kind of mould structure being applicable to cable sheath extrusion molding, the electric wire being beneficial in firm sheath, thus it is beneficial to stable electric property.
The above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of mould structure being applicable to cable sheath extrusion molding, comprises axis and has the mould cover of taper trepanning and cylinder shape trepanning successively, axially has the taper portion that can be placed on described taper trepanning successively and can be placed on the mould core of the columnar part of described cylinder shape trepanning; The through hole running through described taper portion and columnar part it is provided with in the middle part of described mould core; Sheath material outlet is formed between described columnar part outer wall and described cylinder shape trepanning inwall; Described columnar part is along the circumferential direction evenly provided with multiple convex bar.
Preferred as the present invention, described convex bar height is 1-1.5mm.
Preferred as the present invention, described convex bar width is 0.8-1mm.
Preferred as the present invention, the angle between described taper trepanning bus and its axis is 25-30 degree; Angle between described taper portion and its axis is 15-20 degree.
In sum, the present invention has following useful effect: present configuration is simple, is easy to implement; The jacket inner wall that application the present invention is produced has multiple rib bar, thus improves the sticking power of electric wire and jacket inner wall in sheath, thus is beneficial to stable electric property; And for being provided with the cable of skeleton, be also conducive to firm frame position, it is beneficial to stable electric property; And also help saving sheath material.
