Specific embodiment
By the technology contents of utility model are described in detail, construction feature, are reached purpose and efficacy, below in conjunction with implementation
Example simultaneously cooperates attached drawing to be described in detail.
The continuous extruder head 100 of the Blow Molded Articles surface striped of this case includes upper shell 1, lower shell 2, divides
Flow shuttle 3, surface strip streakline flow splitter 4, extrusion die 5.Below in conjunction with 1~attached drawing of attached drawing 5 illustrate each structure composition and
Its working principle；Wherein, continuous extruder head shown in positional relationship and attached drawing 1 up and down described in the present embodiment
Positional relationship it is corresponding, " axial direction " is that upper shell/lower shell/spreader/surface strip streakline flow splitter is upper downward
Direction is stretched, " circumferential direction " is upper shell/lower shell/spreader/surface strip streakline flow splitter radius radiation direction.
As shown in Figure 1 and Figure 2, the continuous extruder head 100 of the Blow Molded Articles surface striped of this case
External structure includes upper shell 1, lower shell 2 and extrusion die 5, wherein lower shell 2 is fixed at the lower end of upper shell 1
In portion, extrusion die 5 is fixed on the lower end of lower shell 2.Internal structure includes that spreader 3 and surface strip streakline shunt
Ring 4, wherein spreader 3 is coaxially set in lower shell 2, and the upper end of spreader 3 extends upwardly in upper shell 1, spreader
The inner wall of 3 outside wall surface and upper shell 1, lower shell 2 inner wall between inner flow passage 31, and upper shell 1 is collectively formed
On be provided with first material entrance 11, which is connected with inner flow passage 31, and so, first material can
Enter inner flow passage 31 by first material entrance 11, and shunts the tubulose material base for forming an entirety by spreader 3.Surface
Streak line flow splitter 4 is coaxially set in the outside in lower shell 2 and being located at spreader 3, sets in the inner peripheral wall of surface flow splitter 4
It is equipped with multiple second materials outlet 41, these second materials outlet 41 connects with the outside wall surface of inner flow passage 31, is used for by the
Multiply streak line is formed on the outer surface for the tubulose material embryo that one material is formed.Extrusion die 5 includes mouth mold 51, is coaxially set in mouth
51 inside of mould and the core model 52 fixed with 3 phase of spreader, form between the inner wall of mouth mold 51 and the outside wall surface of core model 52 and squeeze out
Material path 53, the extrusion manifold 53 are connected with inner flow passage 31, in this way, the tubulose material embryo with multiple streak lines can be by squeezing
53 extruded product of discharging channel.
As shown in 3~attached drawing of attached drawing 5, surface strip streakline flow splitter 4 have connection second material entrance 21 and these second
The transition runner 42 of material outlet 41.Specifically, in the present embodiment, being opened up in the inner peripheral wall of surface strip streakline flow splitter 4
There are 16 second material outlets 41；Transition runner 42 includes 3 lower flow channels being arranged on 4 lower end surface of surface strip streakline flow splitter
Groove 421,12 upper runner grooves 422 being arranged on 4 upper surface of surface strip streakline flow splitter, connection upper runner groove 422
With 5 runner holes of lower flow channel groove 421；Wherein, the lower flow channel groove of inside is located in two neighboring lower flow channel groove 421
421 are narrower than the lower flow channel groove 421 positioned at outside；It is located at the upper runner groove 422 of inside in two neighboring upper runner groove 422
It is narrower than the upper runner groove 422 positioned at outside；And 423 aperture of runner hole in multiple runner holes 423 positioned inside is less than position
In 423 aperture of runner hole in outside, such flow passage structure divides from the lower end surface of surface strip streakline flow splitter 4 towards surface strip streakline
The upper surface of stream ring 4, which is walked, always to be seen, each flow path groove narrows step by step to shoal, to increase the extrusion pressure of second material, is protected
Demonstrate,proving second material can be along each flow path groove by the gentle inflow inner flow passages 31 in second material outlet 41, thus the
Multiply streak line is formed on the outer surface of the tubulose material embryo of one material, finally passes through 53 extruded product of extrusion manifold together.In order to
The smoothness for increasing each flow path groove enables second material can smoothly enter into and converges in inner flow passage 31 with first material,
The surface roughness of each flow path groove is 0.4~0.8, preferably 0.4.And this flow passage structure to shoal that narrows step by step
So that the streak line that second material is formed on the outer surface of tube blank of first material is in the same size, more smooth, beautiful, product
Surface quality it is higher.In other embodiments, the number of upper and lower flow path groove and runner hole is not limited to tool described above
Body quantity, be also possible to it is single or more, in order to enable the streak line formed is more beautiful, surface strip streakline flow splitter
The number of second material outlet is preferably even number, and is arranged circumferentially along it.
The working principle of the continuous extruder head 100 of the Blow Molded Articles surface striped of this case is as follows: the first object
Material is entered in inner flow passage 31 by first material entrance 11, and the tubulose material of an entirety is formed by 3 shunting function of spreader
Embryo, second material are entered in transition runner 42 by second material entrance 21, and reach inside stream by second material outlet 41
Road 31 converges with first material, and forms multiple streak lines in the outer surface of tubulose material embryo, then has the pipe of multiple streak lines
Shape material embryo passes through 53 extruded product of extrusion manifold together.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent changes or modifications made according to the spirit of the present invention should be covered within the scope of the utility model.
