[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip for closing a gap between a vehicle body and a door.

[0002]

2. Description of the Related Art As shown in FIG .
At the door opening, a weather strip made of elastic rubber or sponge rubber is attached to a channel on the body side in order to close a gap between the door and the door.

As shown in FIG. 5, such a weather strip is formed by a rib 2a and a hollow portion 20a.
And a concave groove 3 for fitting into the channel.
Extrusion molding with a mounting base 21a in the part 20a
The general part 1 and, as shown in cross section in FIG.
Rib 2a, hollow portion 20a, groove 3 and mounting base 2 of part 1
1a, the corresponding rib 2b, the hollow portion 20b, the concave groove 3,
An attachment base 21b, which is integrally formed with the terminal of the general part 1.
And a combined molded part 4 as shown in FIG.
As described above, the general part 1 is mounted on a relatively straight portion of the body.
The molded part 4 is attached to the terminal A or the curved part B.

As shown in FIG. 5, the molding of the molding part 4 is performed by loading a core mold 5 into the molding die in order to secure a hollow portion 20b also in the molding part 4, and generally extruding the molding. The part 1 is cut into a predetermined length, and the end is set in a molding die and injection molded.

[0005] The core mold 5 in order to take out the core mold 5 after the molding of the molded part 4, the long handle 5c in the axial direction is protruded, is located the handle 5c to the outside, Katsuko
A To pull out the mold 5, the mounting base 21b of the molded part 4
An opening hole 6 for taking out the core is opened.

[0006] At the both ends or one end of the core mold 5, there is provided an end portion 5b having a groove for allowing the rib 2 of the general portion 1 to escape.

[0007]

As shown in FIG. 6 , after the core mold 5 is removed from the mold forming section 4, the core forming section 4 adheres and closes the opening 6 for removing the core . Since it is within the forming range of the forming part 4, both ends 6a of the opening hole 6 cannot be bonded, thereby causing a bulge 6b on the base surface of the both ends 6a, resulting in poor mounting to the body, and
Poor sealability.

Further, the sectional shape of the molded part 4 is shown in FIG.
As shown in (A), the thickness of the rib 2a is the same as that of the general part 1.
Since there is a single hollow portion 20b in which a large number of hollow portions do not exist, as shown in FIG. 7B, when the glass G comes into contact with the glass G, the glass G is easily depressed and deformed. Leakage occurs. To prevent this, rib 2b
When the thickness of is increased, as shown in FIG.
There are problems such as the occurrence of glass flaw H and impairing the appearance.

[0009] The purpose of the present invention is to apply the molding part to the body.
It is an object of the present invention to improve the attachment and sealing properties, prevent the collapse and deformation , and solve the above-mentioned conventional problems.

[0010]

The gist of the present invention for achieving the above object is that a rib is divided into a hollow portion and a concave groove.
Extruded with a mounting base in the hollow part.
The general part, the rib, the hollow part, the concave groove and the mounting of the general part
It has ribs, hollows, grooves, and mounting bases corresponding to the base.
And a molded part integrally molded with the terminal of the general part.
In a weather strip comprising:
An opening is provided in the mounting base and below the mounting base.
Block that is continuous with the rib of the molded part in the hollow part
And an opening hole for removing the core die is provided in the closing piece .

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes an extruded general portion similar to the conventional one, and a hollow portion 20a and an automobile are formed by ribs 2a.
The concave groove 3 for fitting into the body channel is partitioned
The hollow portion 20a has a mounting base 21a.
You.

Reference numeral 4 denotes a molded part integrally formed with the terminal of the general part 1 in a molding die . The molding of the molded part 4 is performed by injection molding with the core mold 5 loaded in the mold as in the conventional case.

In the present invention, as shown in FIGS. 2 and 3, the molded part 4 has a rib 2a, a hollow part 20a, and a concave groove 3 of the general part 1.
And the rib 2b corresponding to the mounting base 21a and the hollow portion 20
b, the concave groove 3 and the mounting base 21b.

The mounting base 21b of the molded part 4
The opening 22 is provided in the mounting base 21b.
In the lower hollow portion 20b, the rib 2b of the molded portion 4
A continuous closing piece 9 is provided, and the core piece is taken out from the closing piece 9.
In which an opening hole 6 is provided.

With such a configuration, as shown in FIG. 2, the mounting base 21 of the molded part 4 is different from the conventional sectional form of FIG.
b and the hollow below the mounting base 21b
The closing piece 9 continuous with the rib 2b is provided in the portion 20b.
An opening hole 6 for removing the core die was provided in the closing piece 9.
Due to the configuration, the load is increased by the closing piece 9 of the molded part 4 to prevent collapse and deformation, thereby improving the appearance and the sealing performance.

[0016]

[Effects of the invention] As described above, according to the invention, the general
Molded part integrally formed with terminal prevents collapse deformation
And has the advantage of improving the appearance and sealing properties.
