The technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of cross-linked polyethylene insulated cable
Surface colour double-layer coextrusion mold, including front shaft sleeve, colouring tapered sleeve and rear axle housing, one end of the front shaft sleeve be axially inserted into
Into one end of charging seat, be arranged radially feed inlet on the side side wall of the charging seat, the charging seat it is another
End is internal axial to be provided with circular cone inner hole, the conus portion of described colouring tapered sleeve one end be inserted into circular cone inner hole and in circular cone
The inner sidewall in hole is close to, and is provided with that a circle is corresponding with feed inlet to lead glue groove on the lateral wall of the conus portion, described
The two sides of conus portion are symmetrically arranged with V-shaped runner, the turning point in the V-shaped flow road of two sides with lead glue groove and be connected and the V of two sides
The both ends of shape runner are converged in the axial end face of conus portion, and the axial end face of the conus portion is equipped with uniform ring, from two sides
The colorant that flows out of V-shaped flow road be evenly distributed in uniform ring, the other end of the colouring tapered sleeve is connected with rear axle housing.
As a kind of supplement to technical solution described in the utility model, axial one end of the charging seat is provided with
One end of threaded interior hole, the front shaft sleeve is connected with threaded interior hole.
Further, it is provided with screw connecting hole on one end end face of the charging seat, is set on the colouring tapered sleeve
It is equipped with connection through-hole corresponding with screw connecting hole.
Further, the uniform ring is arranged between the end face of conus portion and charging seat in gap and passes through conus portion
Carry out axial compression clamping.
The utility model has the advantages that the utility model relates to a kind of surfaces of cross-linked polyethylene insulated cable to colour double-layer coextrusion mold,
Using completely new colouring mould structure, waste material is significantly reduced when colour changing, and each waste discharge material only needs 1kg or so, is saved every time useless
Expect 2kg-3kg, it is average to save waste material 50kg-75kg daily, 15T-22T waste material is at least saved every year on average, according to market price
13000 yuan/T, saving waste material is often only in calculating can save 200,000 yuan, and furthermore colour changing is also more clean, avoid mixed color phenomenon
Appearance；Since insulator body is true qualities, only surface has a thin layer to colour Insulation Material, also reduces color masterbatch to greatest extent
Influence to quality of insulation；Mould structure is using completely new runner and uses uniform ring, keeps the distribution of color stream pressure more equal
It is even, it can be evenly distributed and sufficiently thin coloring layer.

Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
As shown in Figure 1-3, gathering the technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of be crosslinked
The surface of ethylene insulated cable colours double-layer coextrusion mold, including front shaft sleeve 1, colouring tapered sleeve 3 and rear axle housing 4, the front axle
One end of set 1 is axially inserted into one end of charging seat 2, has been arranged radially feed inlet on the side side wall of the charging seat 2
5, the other end inside of the charging seat 2 is axial to be provided with circular cone inner hole 21, the conus portion 31 of described colouring 3 one end of tapered sleeve
It is inserted into circular cone inner hole 21 and is close to the inner sidewall of circular cone inner hole 21, be provided on the lateral wall of the conus portion 31
One circle is corresponding with feed inlet 5 to lead glue groove 32, and the two sides of the conus portion 31 are symmetrically arranged with V-shaped runner 6, two sides
The turning point in V-shaped flow road 6 with lead glue groove 32 be connected and the both ends in the V-shaped flow road 6 of two sides conus portion 31 axial end face converge
It closes, the axial end face of the conus portion 31 is equipped with uniform ring 7, and the colorant flowed out from the V-shaped flow road 6 of two sides equably divides
For cloth in uniform ring 7, the other end of the colouring tapered sleeve 3 is connected with rear axle housing 4.
Axial one end of the charging seat 2 is provided with threaded interior hole 22, one end of the front shaft sleeve 1 and threaded interior hole
22 be connected, screw connecting hole 23 is provided on one end end face of the charging seat 2, be provided on the colouring tapered sleeve 3 with
The corresponding connection through-hole 34 of screw connecting hole 23.
The uniform ring 7 be arranged between the end face of conus portion 31 and charging seat 2 in gap and by conus portion 31 into
Row axial compression clamps, and facilitates the replacement of uniform ring 7.
As an embodiment of the present invention, the mould structure of present patent application changes material of the material in head
Stream mode, this mould structure are mainly mounted on extruding machine, while extrusion molding machine host squeezes out true qualities insulating outer layer, use note
Machine passes through the runner of this mold, and a thin layer of color is covered outside true qualities.
The vitta that note machine comes out is directly injected by feed inlet 5 leads in glue groove 32, enters back into the V-shaped flow road 6 to two sides
Interior, if it is pervious single channel, stream pressure compares concentration and can not disperse to discharge, and especially entirely coats in insulating surface
When a thin layer color insulate, be extremely difficult to far from note item mouth end stream after extrusion molding, color layers can not all standing, and apart from note item mouth
Hold close color layers thickness very thick, cause after squeezing out side color layers thickness thick and symmetrical side without color layers the phenomenon that.
It is verified by test of many times, to accomplish that whole surface uniformly extrudes a thin layer coloring Insulation Material, need to set runner
Meter is symmetrically distributed, and in order to obtain pressure distribution more evenly, is respectively additionally arranged a spreader again in symmetrical runner,
Form present V-shaped flow road 6, color stream circumference after crossing spreader converges completely, before color stream and true qualities stream are converged
A uniform ring 7 need to be passed through, keep the distribution of color stream pressure more uniform, be evenly distributed and sufficiently thin coloring layer.
The utility model uses completely new colouring mould structure, by extruding a thin layer coloring insulation in insulation outermost layer
The mode of material reduces cost come the colorant wasted when reducing colour changing, improves product quality.
