Abstract
The present invention discloses corner structure of vehicle door and window sealing strip and its making process. The corner structure includes one sealing strip with gaps and injection molded corner blocks to cover the gaps and connected to the sealing strip integrally. Its making process includes extrusion, flocking, cutting, injection molding and other steps. The product has the features of high connection strength, small friction force with vehicle door and window glass and capacity of fitting great angle.
Description
Technical field
The present invention relates to the corner structure of vehicle door and window sealing strip and the manufacture method of self-propelled vehicle.
Background technology
The normally first sealing band of the manufacture method of the vehicle door and window sealing strip of existing self-propelled vehicle by the long vertical bar shape of extruder for shaping, and then be used for door window.The general-duty usage has two kinds at present.A kind of is that the sealing band (call in the following text and extrude bar) of extruding with this long vertical bar shape directly uses according to the shape of door window bending back, its shortcoming is big or extrude the bar cross section when big when corner, the corner section can cause serious deformation, wrinkling, influence cooperates with door window, sealing effectiveness is descended, also influence outward appearance.This kind mode is only used under the little situation of corner at present.Another kind is will extrude the complete severing of bar earlier according to door window frame size to become the billet of appropriate length to connect the angle again, and the common way that connects the angle is on the corner billet to be linked into an integrated entity by injection molding.But owing to be post-cure when connecing the angle to extruding bar, therefore extrude bar and the Joint strenght that connects between the angle lower, produce, transportation and with the process of vehicle window assembling in fracture easily; And owing to extrude the complete severing of bar, so the location is cumbersome in connecing the angle process, workman's operation easier is big, directly influences the yield rate and the oeverall quality of production efficiency, product; Secondly, for the high-grade sealing band that needs flocking in inboard and glass cooperation place, because of flocking face preferably continuous, so can only after connecing the angle and finishing, paste flocking face again, and the sealing band after connecing the angle and finishing is the bending that adapts with door window, so the flocking operation is trouble very, have a strong impact on the efficient and the end product quality of flocking; Moreover; meet the place, angle and more or less have smooth inadequately situation usually; this is for the outside of sealing band and Yan Shangke accepts; but inboard for sealing band; the cooperation place of sealing band and door window glass particularly; then will increase the friction force of door window glass and sealing band, thus the stationarity when influencing door window glass and closing, even produce unnecessary noise.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of Joint strenght height at the prior art present situation and applicable to the corner structure of vehicle door and window sealing strip and the manufacture method thereof of big corner.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this corner structure of vehicle door and window sealing strip, its have one-body molded and extrude bar, extrude bar and be formed with breach in the disconnection of part, corner, indentation, there be coated with this breach suitable connect hornblock, connect hornblock and be injection mo(u)lding and get and be connected as a single entity with the described bar of extruding.
The optimum position of described breach is to be positioned at the described outside of extruding the bar corner.
The described surface that cooperates with the door window glassy phase of extruding bar is provided with flocking face.
The described surface that cooperates with the door window glassy phase of extruding bar is always continuous.
The manufacture method of corner structure of vehicle door and window sealing strip of the present invention is characterized in that may further comprise the steps:
A, extrude: must extrude bar by long vertical bar shape by extruder for shaping;
B, cut:, will extrude the bar part in the position corresponding to the door window corner of extruding bar and cut a bit of and form breach according to door window frame size;
C, injection mo(u)lding: will put into and connect the angle mould tool through the bar of extruding that cuts, and make and extrude bar and be bent into required angle from indentation, there, and inject the rubber fill up the gap, the rubber that the sulfuration back is injected promptly becomes one with the former bar of extruding.
Also be pasted with flocking face before the described cutting step described extruding on bar and the surface that the door window glassy phase cooperates.
The present invention compared with prior art has the following advantage that has:
1,, reduced the corner and extruded the cross-sectional area of bar, thereby eliminated when corner is big corner section easy deformation, wrinkling defective substantially owing on the corner dismiss a part.
2, do not cut into two sections fully owing to extrude bar, still some links to each other, so after connecing the angle sulfuration, has the higher Joint strenght of mode that connects the angle than complete severing again.
Can select when 3, cutting to extrude that some faces do not disconnect in the inner surface of bar,, make flocked surface continuous fully, reduce sealing band and connect the friction force of place, angle with glass such as flocked surface.
4, disconnected owing to not cutting fully, the location is convenient in connecing the angle process, has reduced workman's operation easier, has improved production efficiency and product design.
