Description

[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 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.

[0003] Such a weather strip has a relatively straight portion formed by an extruded part 1 extruded in a hollow shape having a rib 2 and a concave groove 3 for fitting into the channel.
However, the terminal A and the curved portion B are extruded by molding.
It comprises a hollow molded part 4 which is continuously and integrally molded with the terminal of the part 1 .

[0004] As shown in molding 5 of the molded part 4, a core mold 5 is loaded into the mold in order to also secure the hollow portion molded part 4, formed extrusion which is already extruded
The molded part 1 is cut into a predetermined length, and its end is set in a molding die and injection molded.

The core mold 5 is provided with a handle 5 having a wide width L in the axial direction in order to take out the core mold 5 after the molding of the molded portion 4.
A protrusion c is provided, and an opening 6 for taking out a core is inevitably opened in the molded part 4 by the handle 5c.

[0006] Both ends or one end of the core mold 5 is extruded.
It has an end portion 5b having a groove for escaping the rib 2 of the shape portion 1 and is extruded after machining of the molding portion 4 to remove the core mold 5
The slit 1 extends over the end of the forming section 1 and the end of the opening 6.
1 is cut, and the core mold 5 is extracted to obtain a finished product.

[0007]

As described above, conventionally, the width L of the handle 5c of the core mold is almost the entire width in the mold, and the opening hole 6 for removing the core is the same length as the width L of the handle 5c. Therefore, it is impossible to form a rib in the hollow portion of the molded part 4, the load Chunigu the molded part 4 as shown in Figure 6, it is in need of processing operations of inserting the pad 12 to the hollow portion. However, even if the pad 12 is inserted, a dent is generated in the molded part 4 due to the load, and there is a problem that the appearance and the sealing property are impaired.

The object of the present invention is to extrude the hollow part of the molding part.
Rib forming portions enables the molding of a continuous integral ribs and then, the mold
This is to solve the above-mentioned conventional problems by making it easier to tune the load of the molded portion and to prevent the dent.

[0009]

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 portion formed by extrusion molding similar to the conventional one. A hollow portion is formed by a rib 2 and has a concave groove 3 for fitting into a channel of an automobile body.

Reference numeral 4 denotes a molded part integrally formed with the terminal of the extrusion part 1 in a molding die . 5 is this molding part
4 is a core type for forming a hollow shape, and has an end 5b and a handle 5c.

According to the present invention, the width L of the handle 5c of the core mold 5 is determined.
Is shortened as much as possible, and the relief groove of the rib provided at the end 5b is extended to the base of the handle 5c.

The core mold 5 is used to form a mold.
As shown in FIG. 1, the mold forming portion 4 has an opening hole 6 for taking out the core mold, which is opened short, and a rib is formed in a hollow portion of the opening portion 6 for taking out the core mold as shown in FIG. but not, other parts except for the openings 6 for the core type fetch rib 8 as shown in Figure 3 is formed, the rib 8 is extruded
It is continuously integrated with the rib 2 of the molded part 1 .

[0014] Figure 1 for die-cutting of the end portion 5b of the core mold 5 of the molded part 4 of the rib 8, after molding the molded part 4
As shown in FIG. 3, two slits 7 for taking out the core mold are cut across the joint between the extruded part 1 and the molded part 4 .

With such a configuration, it is possible to form the rib 8 in the hollow portion of the molded part 4 and even if the rib 8 exists, the core die 5 can be easily formed by the two core die removal slits 7. It can be die-cut.

Further, the strength of the molded portion 4 is increased by the ribs 8, the load tuning becomes easy, and the dent is prevented.

[0017]

[Effects of the Invention] As described above, according to the present invention, it is possible to form a rib of a molded portion which could not be molded conventionally, thereby enabling load tuning without inserting a pad in a hollow portion. Workability is improved.

Also, the opening hole for taking out the core die is short,
As the strength increases due to the ribs, the dent (crush) of the molded part is confirmed.
In fact, it has the advantage of improving appearance and sealing performance.
