Technical field
The present invention relates to the multi-layer co-extruded crowded head of one kind, more particularly to a kind of mouth mold of multi-layer co-extruded crowded head.
Background technology
During plastic tube double-layer coextrusion, extrusion plug and mouth mold all use traditional structure, need to adjust during ectonexine plastic emitting
Whole extruder head runner gap ensures the uniformity of the gel quantity on section so that after bilayer thickness and degree of eccentricity depanning just more
Plus it is not easy regulation, easily cause glue-line eccentric in extrusion.
The content of the invention
The main object of the present invention is to propose a kind of mouth mold of multi-layer co-extruded crowded head.
To achieve the above object, the present invention provides a kind of multi-layer co-extruded mouth mold, and the mouth mold has inside cavity, outer layer sizing material
Entrance, the first sizing material buffer runner, the first sizing material dashpot, the second sizing material buffer runner, the second sizing material dashpot, the 3rd sizing material
Buffer runner, ring-type sizing material dashpot and the outlet of ring-type sizing material.The first sizing material buffer runner system outer layer sizing material access end edge back of the body
Extend to be formed to extrusion direction, first sizing material dashpot system the first sizing material buffer runner end extends to be formed to both sides direction, the
Two ends of two sizing material buffer runner system the first sizing material dashpots extend to be formed to extrusion direction respectively, the second sizing material dashpot system
Second sizing material buffer runner end extends to be formed to both sides direction, two ends of the 3rd sizing material buffer runner system the second sizing material dashpot
End extends to be formed to extrusion direction respectively, and the end of the 3rd sizing material buffer runner is connected with ring-type sizing material dashpot, ring-type sizing material
Dashpot extends inwardly to form the outlet of ring-type sizing material along after dorsad extrusion direction extension.
Preferably, the first sizing material dashpot is 180 degree endless groove.
Preferably, the groove inwall between ring-type sizing material dashpot and ring-type the sizing material outlet extends into groove forms convex
Press section.
As described above, the outer layer sizing material of multi-layer co-extruded mouth mold of the invention enters from outer layer sizing material entrance, it is slow through the first sizing material
Swash of wave road enters the first sizing material dashpot, the second sizing material buffer runner is branched to by the first sizing material dashpot thereafter, by the second glue
Material buffer runner flow to the second sizing material dashpot, then branches to the 3rd sizing material buffer runner by the second sizing material dashpot, and by
3rd sizing material buffer runner is squeezed into the outlet of ring-type sizing material, the sizing material of the first sizing material buffer runner into ring-type sizing material dashpot
Flow direction and extrusion are in opposite direction, and sizing material flow direction is also with extruding direction in the groove between ring-type sizing material dashpot and the outlet of ring-type sizing material
On the contrary, and with the first sizing material dashpot, the second sizing material dashpot and ring-type sizing material dashpot, these structures and design equal energy
So that outer layer sizing material obtains evenly closely knit extruding so that the outer layer of extrusion can thickness it is uniform.
Brief description of the drawings
Fig. 1 is the multi-layer co-extruded example structure schematic diagram of mouth mold one of the invention；
Fig. 2 is the profile of multi-layer co-extruded mouth mold shown in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art obtained under the premise of creative work is not made it is all its
His embodiment, belongs to the scope of protection of the invention.
Fig. 1 and Fig. 2 are referred to, multi-layer co-extruded mouth mold of the invention has inside cavity h, outer layer sizing material entrance 10, the first sizing material
Buffer runner 20, the first sizing material dashpot 30, the second sizing material buffer runner 40, the second sizing material dashpot 50, the 3rd sizing material buffering
Runner 60, ring-type sizing material dashpot 70 and ring-type sizing material outlet 80.
First sizing material buffer runner 20 is that the end of outer layer sizing material entrance 10 extends to be formed along dorsad extrusion direction, the first sizing material
Dashpot 30 is that the end of the first sizing material buffer runner 20 extends to be formed to both sides direction, and the second sizing material buffer runner 40 is the first glue
Expect that two ends of dashpot 30 extend to be formed to extrusion direction respectively, the second sizing material dashpot 50 is the second sizing material buffer runner 40
End extends to be formed to both sides direction, and the 3rd sizing material buffer runner 60 is two ends of the second sizing material dashpot 50 respectively to extrusion
Direction extends to be formed, and the end of the 3rd sizing material buffer runner 60 is connected with ring-type sizing material dashpot 70, ring-type sizing material dashpot 70
Ring-type sizing material outlet 80 is extended inwardly to form along after dorsad extrusion direction extension.
As further improvement of this embodiment, the first sizing material dashpot is 180 degree endless groove.
As further improvement of this embodiment, the groove between ring-type sizing material dashpot 70 and ring-type the sizing material outlet 80
Inwall extends into groove forms convex press section c.
In summary, the outer layer sizing material of multi-layer co-extruded mouth mold of the invention enters from outer layer sizing material entrance 10, through the first sizing material
Buffer runner 20 enters the first sizing material dashpot 30, branches to the second sizing material buffer runner by the first sizing material dashpot 30 thereafter
40, the second sizing material dashpot 50 is flow to by the second sizing material buffer runner 40, then the 3rd is branched to by the second sizing material dashpot 50
Sizing material buffer runner 60, and it is squeezed into the outlet of ring-type sizing material into ring-type sizing material dashpot 70 by the 3rd sizing material buffer runner 60
80, the sizing material flow direction of the first sizing material buffer runner 20 is in opposite direction with extrusion, and ring-type sizing material dashpot 70 is exported with ring-type sizing material
Sizing material flow direction is also in opposite direction with extrusion in groove between 80, and with the first sizing material dashpot 30, the second sizing material dashpot 50
And ring-type sizing material dashpot 70, these structures and design are equal to cause outer layer sizing material to obtain evenly closely knit extruding, so that
Enable to extrusion outer layer can thickness it is uniform.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every at this
