Description
Technical field
The present invention relates to a kind of cable extruding mold, specifically a kind of double-colored cable extrusion die belongs to wire and cable system
Manufacturing apparatus technical field.
Background technique
Cable is needed in process of production using mold core and die sleeve, such mold core and die sleeve such as Authorization Notice No.
Die sleeve structure: the mold core and die sleeve of cable production squeezing type matching mold disclosed in CN201006632Y are provided with an extrusion molding loudspeaker
Mouthful, it is provided at bell-mouthed small-bore place and holds diameter (also referred to as die sleeve corridor is long)；Mold insert structure: it is provided with the loudspeaker of a conductor extrusion molding
Mouth is provided at bell-mouthed small-bore place and holds diameter, and the leading exterior surface of mold core is inclined-plane, and the inclined-plane of leading exterior surface is always
Extend to end face.When mold core and die sleeve are used cooperatively, the front end of mold core is in the horn mouth of die sleeve.
With the fast development of electric power and the communications industry, cable is many kinds of using increasingly extensive, with cable products kind
The increase of class, the moulds of industrial equipment (mold core and die sleeve) of existing cable plastic extrusion, is not able to satisfy the modeling of some specialities
Material squeezes out processing request, and researching and developing new moulds of industrial equipment is particularly important.
In double-colored cable production process, existing double-colored cable plastics extrusion die can not accurately control secondary color covering
Rate or secondary color width.In use, it needs to be required according to secondary color, is met the requirements by adjusting extruder revolving speed, do not have standard
The function of true control room color coverage rate or secondary color width.
Currently, control room color coverage rate or secondary color are wide during double-colored cable plastic extrusion in double-colored cable production process
Degree is main in the following manner:
1, by increaseing or decreasing the width of mold secondary color runner, reach the secondary color coverage rate met the requirements or secondary color width
Requirement.Since in material in a mold flow process, there are diffusions and shrinkage phenomenon, mold secondary color runner is increasedd or decreased
Width, cannot accurate control room color coverage rate or secondary color width.
2, the revolving speed that machine equipment is squeezed out by increaseing or decreasing secondary color, reaches the secondary color coverage rate met the requirements or secondary color is wide
The requirement of degree.Since in material in a mold flow process, there are diffusions and shrinkage phenomenon, increaseds or decreases secondary color extruder and set
Standby revolving speed, can not accurate control room color coverage rate or secondary color width.
3, by rationally matching mould, selection can be realized the mold for meeting coverage rate requirement, reach wrapping between meeting the requirements
The requirement of lid rate or secondary color width.Horizontal difference is tested since Product Process is horizontal and squeezes out machine host hand channel to have not when matching mould
The same matches mould as a result, leading to there is a situation where that secondary color coverage rate or secondary color width are inconsistent, homogeneity of product with a collection of product
It is poor.
Summary of the invention
The object of the present invention is to provide a kind of double-colored cable extrusion die, which can accurately control secondary color covering
Rate or secondary color width.
In order to reach above-mentioned technical purpose, the technical scheme is that
A kind of double-colored cable extrusion die, including die sleeve, the die sleeve is by extrusion molding horn mouth and holds diameter and constitutes, described to hold diameter
Positioned at bell-mouthed small-bore place, secondary color runner is provided on the die sleeve, the discharge port of the secondary color runner, which is located at, to be held at diameter.
If extrusion plastic is squeezed into from flared end, by runner as defined in mold, squeezed out holding diameter (corridor length or sizing area),
As horn mouth becomes smaller, extruded material has the process of diffusion and contraction.Wherein, diffusion main cause has a two o'clock: first, be because
Cause for extrusion plastic by the machining deformation of mold；Second, because extrusion plastic needs the machining deformation by mold, secondary color
The revolving speed size of extruder is also the main reason for influencing diffusion phenomena
Secondary color discharge port is embedded into and holds diameter (corridor length or sizing area), the processing that secondary color extrusion plastic does not pass through mold becomes
Shape does not have the process of diffusion and contraction.In addition, there are three types of cable extruding mode is general: squash type, half squeeze (pipe) formula, squeeze
Tubular type, no matter which kind of extrusion way, hold the material after diameter (corridor long or sizing area) squeezes out through mold, be that equal proportion is shunk or swollen
It is swollen to be attached at cable, it is to require to calculate according to cable secondary color, so as to standard when we process the size of secondary color discharge port
True control room color coverage rate and secondary color width.
The size of the discharge port is calculated according to the requirement of color coverage rate or width.
Secondary color runner discharge port position is embedded in die sleeve and holds diameter (i.e. in corridor length) by double-colored cable extrusion die of the invention,
It solves material diffusion in a mold and shrinkage phenomenon, improves the precision of secondary color coverage rate or secondary color width, while also mentioning
High production efficiency, reduces double-colored product repair rate and rejection rate, ensure that product quality.It is easy to operate, to the experience of extrusion
It is required that it is lower, it ensure that the consistency of product.
Detailed description of the invention
Fig. 1 is die sleeve sectional view.
Fig. 2 is die sleeve top view.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, 2, a kind of double-colored cable extrusion die, including die sleeve 1, the die sleeve 1 is by extrusion molding horn mouth 2 and holds
Diameter 3 is constituted, the small-bore place held diameter 3 and be located at horn mouth 2, is provided with secondary color runner 4, the secondary color stream on the die sleeve 1
The discharge port 5 in road 4, which is located at, to be held at diameter 3.
According to the requirement of cable products secondary color coverage rate or width, waits and go out to correspond to secondary color in die sleeve 1 and go out than Extrapolation
The size of material mouth 5.
Above-described embodiment is not limit the invention in any way, all to be obtained by the way of equivalent substitution or equivalent transformation
Technical solution fall within the scope of protection of the present invention.
