Description
Technical field
The present invention relates to a kind of extrusion dies, more particularly, to a kind of extrusion die of the double-colored tubing of horizontal line.
Background technique
Warning rod bar is commonly used in the stream of people and the intensive public arena of wagon flow, for pedestrian or vehicle are warned and every
From, such as in urban road crossing, pavement, parking lot and interim opening job location etc..Under normal circumstances, multiple warning rods
It is used cooperatively simultaneously, is arranged in corresponding isolation route, to play warning to the vehicle of pedestrian or traveling or stop interception
Effect, so that passing pedestrian or vehicle move along the range of warning rod warning outside, therefore warning rod consciously orderlyly
Using more and more frequent and more and more important.
Warning rod is generally equipped at intervals with two kinds of colors, and daytime, color was eye-catching, can reflect dazzling radiance at night, reminds
Driver, pedestrian etc. pay attention to.In the prior art, the color on warning rod is all made of artificial colouring, is manually warning paintbrush
On bar, or paster is used, paster is attached on warning rod.But it according to the mode of brush paint, will cause on warning rod
Color is smeared unevenly, and low efficiency, and uses paster, and because warning rod is used in outdoor, paster is easy to damage, and service life is short,
And it can not be played a warning role after paster damage.
The content of present invention
The purpose of the present invention: in order to overcome the drawbacks of the prior art, the present invention provides a kind of double-colored tubing compound extrudeds of horizontal line
Mold, when tube forming squeezes out, so that it may automatic compound feeding is carried out to tubing, it is more convenient compound in this way and compound more equal
It is even.
A kind of technical solution of the present invention: double-colored tubing composite extruding mould of horizontal line, which is characterized in that including head, institute
It states and is equipped with tubing stock mould in head, the head is equipped with colorant storage cavity, and the colorant storage cavity is fed equipped with colorant
Mouthful, sliding die sleeve is equipped with sliding die sleeve on the head, and tubing tapping channel, institute are equipped between the head and tubing stock mould
It states head and is equipped with the colorant tapping channel communicated with colorant storage cavity, the sliding die sleeve slides controllable colorant tapping channel
Open and close, the control device for driving sliding die sleeve sliding is additionally provided on the head.
By adopting the above technical scheme, while tube extrusion, control device control sliding die sleeve is to far from colorant storing
Cavity direction sliding, so that colorant tapping channel is opened, it can be compound to tubing progress, after the completion of compound, control device control sliding
Die sleeve slides to close to colorant storing cavity direction, colorant tapping channel is closed, such colorant would not flow on tubing, make pipe
Two kinds of colors are presented in material, realize the processing of double-colored tubing, using the method for this automation processing, so that tubing feeding is more equal
It is even and compound more convenient.
The further setting of the present invention: the sliding die sleeve is equipped with the discharge gate communicated with colorant tapping channel, described
Head is equipped with the partition for controlling discharge gate open and close, and the partition, which is slidably located in, slides the periphery of die sleeve, goes out in colorant
When expecting that channel is closed, partition, which exposes discharge gate, keeps discharge gate in the open state, and when colorant tapping channel is opened, partition is blocked
Discharge gate is in close state discharge gate.
Using above-mentioned further setting, the setting of discharge gate is in order to when colorant circulation passage is closed, colorant circulation passage
Interior colorant can be discharged from discharge gate, make the pressure in colorant circulation passage not too big in this way, beat in colorant circulation passage
When opening, discharge gate is closed, and colorant is enable to flow in tubing tapping channel in this way, compound to tubing progress, is arranged so more
It is convenient, efficient.
Further setting of the invention: the control device includes actuator, and the sliding die sleeve is equipped with several
Reset spring, the reset spring conflict are arranged on the lateral wall of colorant storage cavity, and the sliding die sleeve periphery is equipped with and is used for
Limitation sliding die sleeve is detached from the limit plate of head, when actuator drives partition movement to slide to separate colorant storing cavity direction,
So that discharge gate is closed, reset spring can push sliding die sleeve to far from colorant storing cavity direction, so that colorant tapping channel
It is connected with pipeline tapping channel, drives partition to when sliding close to colorant storing cavity direction in actuator, partition can be by discharge gate
Expose so that discharge is opened, the sliding of sliding die sleeve can compress reset spring so that colorant channel and tubing tapping channel are closed.
Further it is arranged using above-mentioned, actuator drives partition to when sliding far from colorant discharging cavity direction, slides mould
Set can be under the active force of reset spring simultaneously to far from colorant discharging cavity direction sliding, and limit plate is sliding for limiting sliding die sleeve
The distance of shifting makes it that can only slide certain distance, so that colorant circulation passage is opened, colorant is passed to tubing tapping channel
On, compound to tubing progress, discharge gate can be closed because of blocking for partition, facilitate the circulation of colorant, after the completion of compound, be driven
When moving part drives partition to slide to colorant storing cavity direction, it will drive sliding die sleeve to colorant discharging cavity direction sliding, will reset
Spring is compressed, and at this moment colorant circulation passage can close, and colorant will not flow to tubing tapping channel, and partition can be by discharge gate
Expose, the colorant in colorant circulation passage will be discharged from discharge gate, and the pressure in colorant circulation passage is made to become smaller, and be arranged in this way
Meeting so that tubing formed two sections of colors it is different, realize the double-colored compound of tubing.
