Abstract
The utility model discloses a kind of two automotive compounded sealing strip extrusion neck ring mold, this pair of automotive compounded sealing strip extrusion neck ring mold comprises cope match-plate pattern and lower bolster; Cope match-plate pattern and lower bolster are respectively equipped with first flow entrance and first flow outlet, the second flow channel entry point, the second runner exit, enter glue amount by what control each solation road, well solve formation problems.Second runner exit both as sizing material runner exit, also as exhaust passage, can can prevent the vibration of the excessive production equipment caused of pressure simultaneously, ensure the continuous stability produced; By the sealing strip that two compound extruded mouth mould is produced, solve single material air regulator sealing strip in prior art and can not meet retaining part simultaneously and have stronger chucking power and scrap (bridge) moderate finite deformation but to have the requirement of less elastic force, meet Production requirement.
Description
Technical field
The utility model relates to a kind of two automotive compounded sealing strip extrusion neck ring mold, belongs to auto parts technical field of mold.
Background technology
Weather strip for automobile extrusion neck ring mold is the capital equipment of sealing strip extrusion molding, plays an important role to the quality of the shape of sealing strip product, structure and product; In the prior art, automobile air window sealing strip is by dense rubber extrusion molding, and the structure of extrusion neck ring mold is also fairly simple; Extrusion neck ring mold is made up of single mode plate, and the centre of extrusion neck ring mold is extruder die; The air regulator sealing strip of tradition die extrusion can not meet retaining part simultaneously has stronger chucking power and scrap (bridge) moderate finite deformation but to have the requirement of less elastic force, air regulator sealing strip is to compound future development, and therefore corresponding extrusion neck ring mold can not meet Production requirement.
Summary of the invention
The purpose of this utility model is: for the defect of prior art, provides a kind of two automotive compounded sealing strip extrusion neck ring mold, can produce the automobile air window sealing strip meeting sealing property simultaneously and install steadiness, to overcome the deficiencies in the prior art.
The technical solution of the utility model
A kind of two automotive compounded sealing strip extrusion neck ring mold, comprise cope match-plate pattern and lower bolster, the centre, side of lower bolster is the first glue flow channel entry point; There are bolt hole and through hole in the surrounding of the first glue flow channel entry point; Lower bolster opposite side centre is the shape of the mouth as one speaks of sealing strip retaining part, and this shape of the mouth as one speaks is corresponding with the shape of the mouth as one speaks of cope match-plate pattern sealing strip retaining part; The side of the lower bolster retaining part sealing strip shape of the mouth as one speaks is solation road, and side, solation road is the second glue flow channel entry point, and opposite side is the second glue runner exit; Cope match-plate pattern centre is the complete sealing strip shape of the mouth as one speaks, and this shape of the mouth as one speaks is the first glue runner exit; The bolt hole one and through hole one with inner convex platform is had around the shape of the mouth as one speaks; Cope match-plate pattern and lower bolster are by being connected with connector.
In aforesaid two automotive compounded sealing strip extrusion neck ring mold, the first solation road becomes 60 degree of inclination angles with lower bolster surface.
Owing to have employed technique scheme, compared with prior art, the utility model is respectively equipped with first flow entrance and first flow outlet, the second flow channel entry point, the second runner exit on cope match-plate pattern and lower bolster, glue amount is entered by what control each solation road, well solve formation problems, the second runner exit both can as sizing material runner exit, also can as exhaust passage, the vibration of the excessive production equipment caused of pressure can be prevented simultaneously, ensure the continuous stability produced.By the sealing strip that two compound extruded mouth mould is produced, solve single material air regulator sealing strip in prior art and can not meet retaining part simultaneously and have stronger chucking power and scrap (bridge) moderate finite deformation but to have the requirement of less elastic force, meet Production requirement.
For meeting the requirement of front windshield sealing strip performance and the two compound extruded mouth moulds manufactured, not only meet Production requirement; Be vented the vibration of the production equipment freely do not caused simultaneously when solving production, ensure the continuous stability produced; Second runner exit is conducive to the control of pressure, protects production equipment.

Detailed description of the invention
Below in conjunction with accompanying drawing to the utility model with being described in further detail, but not as to any restriction of the present utility model.
Embodiment of the present utility model: a kind of two automotive compounded sealing strip extrusion neck ring mold, as shown in accompanying drawing 1-4, comprises cope match-plate pattern 8 and lower bolster 1; The centre, side of lower bolster 1 is the first glue flow channel entry point 4; There are three bolts hole 3 and two through holes 2 in the surrounding of the first glue flow channel entry point 4; Lower bolster 1 opposite side centre is the shape of the mouth as one speaks 5 of sealing strip retaining part, and this shape of the mouth as one speaks 5 is corresponding with the shape of the mouth as one speaks of cope match-plate pattern 1 sealing strip retaining part; The side of the lower bolster 1 retaining part sealing strip shape of the mouth as one speaks 5 is solation roads 10, and side, solation road 10 is the second glue flow channel entry point 7, and opposite side is the second glue runner exit 6; Cope match-plate pattern 8 centre is the complete sealing strip shape of the mouth as one speaks 14, and this shape of the mouth as one speaks 14 is the first glue runner exit; Three bolt hole 1 and two through holes 1 with inner convex platform are had around the shape of the mouth as one speaks 14; Cope match-plate pattern 8 and lower bolster 1 by being connected with connector, and are fixed on extruder head; As shown in Figure 5, the first solation road becomes 60 degree of inclination angles with lower bolster surface, reduces the impact of counterpart mould when sizing material flows, is beneficial to the eliminating of gas; Because extrusion neck ring mold is arranged on head, when sizing material melt flows pressure hour, the second glue runner exit 6 is closed by head; When sizing material melt flows pressure is excessive, the second glue runner exit 6 is in non-closed state; Therefore can play a protective role; The first sizing material is by the first solation road 9 and solation road 12, and the second sizing material is by solation road 10 and solation road 12, and co-extrusion becomes automotive compounded air regulator sealing strip, and automotive compounded front windshield sealing strip as shown in Figure 6.
