JPH0648257A - Die forming part of weather strip in hardtop car - Google Patents

Abstract

PURPOSE:To prevent lip creases from occurring and enable it to enlarge its wall thickness regardless of the formation of any gas blemish in addition to making any pad disusable by constitution a die forming part with soft solid rubber of JIS (A) hardness 10-30. CONSTITUTION:A weather strip 10 is attached to a body panel 50 and comes into elastically contact with door glass 40, sealing a gap between this door glass 40 and a body panel 50. A die forming part 20 set up in a corner part of the weather strip 10 consists of soft solid rubber Q of JIS (A) hardness 10-30. Therefore, even if a lip 25 of the die forming part 20 is pressed by a trim 60, there are no creases produced in this lip 25 and, what is more, if wall thickness in a part elastically contacting with the door glass 40 is increased to some extent, no gas blemish is formed there, thus any pad is disusable.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a die-molded portion of a weatherstrip for a hard top vehicle, and particularly to a material thereof.

[0002]

2. Description of the Related Art A description will be given with reference to FIGS. In the figure, one of the median lines from the apex angle of the isosceles triangle is filled, but the filled side represents the molding part, and the non-filled side represents the extrusion molding part. . Conventionally, a mold forming portion 8 such as a corner portion of a weather strip 10 of a hard top vehicle that is elastically contacted with the door glass 40 and seals between the body panel 50 and the door glass 40.
For 0, sponge rubber P was used. 3
0 and 30 are extrusion molding parts connected to the mold molding part 20,
Reference numeral 60 is a trim that wraps with the lip 85 of the molding portion 80.

In the conventional molded portion 80 of the weather strip 10, the lip 85 overlapping the trim 60 is pushed and deformed by the trim 60, and wrinkles 86 are easily generated on the outer surface thereof. Further, in order to increase the reaction force of the mold forming portion 80 and improve the sealing property, it is necessary to increase the wall thickness.
Since gas scratches are generated in a portion where the door glass 40 elastically contacts, there is a problem in that the pad 70 needs to be inserted into the hollow portion in order to avoid this. Also in FIG.
I had a similar problem.

[0004]

The problem to be solved is that the mold forming part 8 of the conventional weather strip 10 described above is used.
In the case of 0, wrinkles 86 are easily generated on the outer surface of the lip 85 that wraps with the trim 60 or the seaming welt, and the mold forming portion 8
If the wall thickness is increased in order to increase the reaction force of 0 and improve the sealing property, gas scratches are generated in the portion where the door glass 40 elastically contacts.

[0005]

Means for Solving the Problems An explanation will be given with reference to FIGS. 1, 2 and 5. The present invention relates to a mold forming part 20 of a weather strip 10 of a hard top vehicle, which is a JIS (A)
It is a mold molding part made of a soft solid rubber Q having a hardness of 10 to 30.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Explaining an embodiment, 10 is a weather strip of a hard top vehicle attached to a body panel 50, which makes elastic contact with the door glass 40 and seals between the door glass 40 and the body panel 50. It is a thing. Reference numeral 20 denotes a molded portion arranged at the corner portion or the like, which is made of a soft solid rubber Q and has its lip 25 wrapped with the trim 60. 30, 30
Is an extrusion molding part connected to both sides of the molding part 20.

The operation will be described. Since it is made of the soft solid rubber Q having JIS (A) hardness of 10 to 30, the lip 25 does not cause wrinkles even when pushed by the trim 60, and the door glass 40 and the elastic body Even if the thickness of the contacting part is increased, gas scratches are not generated and the pad can be eliminated. If the hardness of the solid rubber is high, the hardness difference between the extruded molded part and the sponge part is large, which causes a problem in sealing property. On the other hand, if it is set too low, the sealing force will be reduced, causing a problem in the sealing property.

[0008]

Since the present invention is constructed as described above,
The lip 25 that overlaps the trim 60 does not have wrinkles, and the wall thickness can be increased without worrying about the generation of gas scratches. Therefore, the pad can be eliminated.
