Abstract
The invention relates to a diverter for an automobile sealing strip extrusion head. The diverter is provided with a diverter main body, a triangular protrusion and a groove, wherein the diverter body is cylindrical; chamfers are respectively arranged at two ends of the diverter body; the triangular protrusion is positioned on the surface of the diverter; the groove comprises a main rubber group consisting two branched runners and a secondary runner group consisting of another two branched runners; the main runner group is communicated with the secondary runner group. The diverter has the advantages that the possibility that a sizing material is retained and burnt down is reduced; when an extrusion pressure is increased, the phenomenon that a mouth die is blocked by the clinker due to the fact that the sizing material clinker punches out of the mouth die is avoided.
Description
Technical field
The present invention relates to rubber extruding equipment technical field, specifically, is a kind of weather strip for automobile extruder head current divider.
Background technology
At present, can extrude all kinds of EPDM rubber products by rubber extruding equipment as extruder head, technical process is: first by plastic heating, make it to be viscosity flow state, pass through current divider, enter effigurate mouthful of die body of tool, become the similar non-individual body of cross sectional shape, then, by cooling, the plastics rheid that makes it have certain geometrical shape and size becomes elastomeric state, last cooling and shaping is glassy state, obtains needed goods.
In prior art about the current divider of automobile extruder head as shown in Figure 1; comprise current divider body 10; in the middle of current divider body 10, be provided with fluid passage 11; due to fluid passage 11, pressure is inhomogeneous everywhere; easily be detained at pressure rill body tunnel ends 12 place's sizing materials, burn, cause in the time that extrusion pressure increases; there will be sizing material grog to rush outlet mold, or a mouthful mould warning is shut down
Chinese patent literature CN200910049763.4, April 22 2009 applying date, patent name is flow divider for nose, disclose and a kind ofly can make plastic polymer after melting reduce to being subject to material resistance in the process of machine head port mould by current divider, pressure is fully discharged, flow equalization, volume is stable, the uniform flow divider for nose of flowing velocity.But be detained about overcoming sizing material, the current divider burning yet there are no report.
Summary of the invention
The object of the invention is for deficiency of the prior art, provide one to overcome sizing material and be detained, the weather strip for automobile extruder head current divider burning.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of weather strip for automobile extruder head current divider.Described current divider is provided with current divider body, triangular hill, groove; Described current divider body is column type, and its two ends are equipped with chamfering; Described triangular hill is positioned at the surface of current divider; Described groove comprises by two runners and becomes the sprue group of forked and the secondary fluid course group that is become forked by another two runners, described sprue group and secondary fluid course Zu Shi UNICOM.
Described triangular form raised brim is that circular arc is excessive.
Two runners of described sprue group are in a certain angle, and two runners of described secondary fluid course group are in a certain angle.
The runner of the runner of described sprue group and described secondary fluid course group seamlessly transits, and groove bottom side is circular arc, and two runners are streamlined and seamlessly transit, and avoid dead angle buildup.
What two runners of described sprue group arranged employing is setting from the superficial to the deep, makes molten mass in extrusion, and pressure is fully discharged, and to ensure the even of clad, thickness is consistent.
Two flow passage directions of described sprue group are dispersed, and two flow passage directions of described secondary fluid course group are gathered.
The invention has the advantages that:
1, sizing material is difficult for being detained, and burns
2, simple in structure, easy to use, safe and reliable
3, when extrusion pressure increases, sizing material grog can not rush outlet mold, causes mouthful mould dead by grog gambling, and pressure alarm is shut down.

embodiment 1
Please refer to Fig. 2, Fig. 2 is a kind of weather strip for automobile extruder head diversion structure schematic diagram of the present invention.Described current divider is provided with current divider body 20, groove 21, triangular hill 22.
Described current divider body 20 is column type, and its two ends are equipped with chamfering 32(and see Fig. 3); Described triangular hill 22 is positioned at the surface of current divider; Described groove 21 comprise by two runners become the sprue group 30(of forked to see Fig. 3) with become the secondary fluid course group 31(of forked to see Fig. 3 by another two runners), described sprue group 30(is shown in Fig. 3) with secondary fluid course group 31(see Fig. 3) be UNICOM.
Please refer to Fig. 3, Fig. 3 is a kind of weather strip for automobile extruder head current divider front view of the present invention flow regime figure that holds concurrently.
Described sprue group 30 is positioned at triangular hill 22(and sees Fig. 2) right-hand member, the secondary fluid course group 31 of telling is positioned at triangular hill 22 left ends; The runner of the runner of described sprue group 30 and described secondary fluid course group 31 seamlessly transits, and groove 21(is shown in Fig. 2) bottom be circular arc, two runners are streamlined and seamlessly transit, and avoid dead angle buildup.
Please refer to Fig. 4, Fig. 4 is that a kind of weather strip for automobile extruder head current divider rock of the present invention axially launches the schematic diagram flow regime figure that holds concurrently.
Described sprue group 30(is shown in Fig. 3) be provided with sprue group first flow 41 and sprue group the second runner 42, in a certain angle; Described secondary fluid course group 31(is shown in Fig. 3) be provided with secondary fluid course group first flow 43 and secondary fluid course group the second runner 44, in a certain angle; Described sprue group 30(is shown in Fig. 3) two runners arrange employing is setting from the superficial to the deep, make molten mass in extrusion, pressure is fully discharged, with ensure clad evenly, thickness is consistent.
It should be noted that: two flow passage directions of described sprue group 30 are dispersed, two flow passage directions of described secondary fluid course group 31 are gathered.In the time that extruder head pressure is too small, because 31 flow direction of sprue group 30 and secondary fluid course group is not consistent, the Fluid Circulation of sprue group 30 and secondary fluid course group 31 flows, the sizing material being detained because pressure is little in sprue group 30, can flow and supplement by the fluid of secondary fluid course group 31, the sizing material being detained because pressure is too small in secondary fluid course group 31 can be supplemented by sprue group 30 streaming flows, avoid the accumulation of sizing material, in the time that extruder head pressure is excessive, fluid in sprue group 30 enters in secondary fluid course group 31, avoid sizing material to burn, rush outlet mold, cause mouthful mould dead by grog gambling, pressure alarm is shut down.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the inventive method; can also make some improvement and supplement, these improvement and the supplementary protection scope of the present invention that also should be considered as.
