An extruded assembly part 12 made of rubber and an extruded seal part made of sponge rubber are integrally molded at a joining line 10, and the parts where the extrusion molded products are connected, such as corner parts, are connected to the molded seal part 21. Both the molded assembly parts 22 are injected with sponge rubber and integrally connected by molded parts.

いる。FIG. 5B shows an example of a conventional drip molding for automobiles, in which the extruded molded part 1 is made up of an extruded assembly part 12 made of solid rubber and an extruded seal part 11 made of sponge rubber, which are integrated at an extruded joint line IO. Molded. In order to give priority to the sealing function between the joint ends 20 of the extrusion molded part l, both the molded seal part 21 and the molded assembly part 22 are molded with the same solid rubber as the extrusion assembly part 12 and are integrally connected. has been done.

形部は単一材料で成形していた。That is, in the case of conventional weather strips for automobiles that have an assembly part and a seal part, the extrusion molding part uses solid rubber for the assembly part and sponge rubber for the seal part, so that the parts required for each are made of solid rubber. However, since the joint part is integrally molded by molding, the molded part is made of a single piece, either by using the same material as the assembly part or by using the same material as the sealing part. It was molded from one material.

Due to the later stretching, a step was created at the joint end 20, resulting in uneven sealing action, and due to the difference in sealing action between sponge rubber and solid rubber, a uniform sealing function could not be obtained.

As shown in FIG.
A projecting edge 71 is provided at the mold position that forms the connection part with 2, and the sealing member and the assembly member are injected from the inlet 8 and the inlet 9, respectively, so that the two are properly integrated and formed. However, the seal portion 21 and the assembly portion 22 are simultaneously molded while providing resistance to the flow of one material toward the other by the protruding edge 71.

、２ｍの一般肉厚で押出し成形した成形品を用いた。[Example 1] A conventional molded product was used for the extrusion molding part. That is, an extruded assembly part 12 with a retaining lip 13 for retaining the flange on the inner surface and an insert iron plate 14 inserted therein was attached with solid rubber to the outside of one side of the assembly part at a joining line 10. A molded product was used in which the tubular seal portion 11 was integrally extruded from sponge rubber and had a general thickness of 2 m.

There is a medium assembly part 6 with a length corresponding to oOa+-, and a height H is IIIIIIl and a protrusion length P is 1111I+ at the bottom of the tip.
The seal part medium size 7 has a projecting edge 71 and has the same length as the assembly part medium size.
The molds were overlapped and clamped with upper mold 3.

かった。Next, from the injection port 8 for the sealing part, apply the same sponge rubber paste as the sponge rubber of the sealing part 11 of the extrusion molding part, and from the injection port 9 for the assembly part, apply the same sponge rubber paste as the solid rubber of the assembly part 12 of the extrusion molding part. of solid rubber paste in channel 8.
1 and 91 at the same time. After vulcanization molding,
When the upper mold 3 was removed and each middle mold was removed, a weather strip having the shape shown in FIG. 1A and joined at the molding part 2 was obtained. In the obtained weather strip,
The joining state between the assembly part 22 and the sealing part 21 in the molding part 2 is such that the solid rubber on the assembly part side presses the sponge rubber on the sealing part side, so that the joint line 10' of the molding part has entered the sponge rubber side by R (a little more than 1 mm) from the joining line 10 of the extrusion molded part, but the thinned part due to the mold ridge 71 at the base of the seal part of the sponge rubber becomes solid rubber. Therefore, the portion of the sponge rubber seal portion with a general wall thickness of 2 cm, which is thinned by the protruding length P (1a+m) of the mold ridge 71, is substantially made of a solid material that is much more rigid than sponge rubber. Since it was made of rubber, there was no problem with the sealing action of the sponge rubber seal part.

Although the seal part 21 has a narrow slit opening O for pulling out the seal, there was no problem in its operation. However, the opening O can be closed with adhesive if necessary.
また、型成形部２のシール部２１は押出成形部１のシー
ル部１１と均質のスポンジゴムであるため、製品の接合
端部２ｏの段差は目立たない程度であった。Moreover, since the sealing part 21 of the molding part 2 was made of sponge rubber homogeneous with the sealing part 11 of the extrusion molding part 1, the difference in level at the joint end 2o of the product was not noticeable.
得られた製品にあっては、シール部及び組付部が押出成

支障が生じなかった。In the obtained product, since both the extrusion molding part 1 and the molding part 2 of the sealing part and the assembly part are made of the same material, the sealing part exhibits a uniform sealing effect without creating any gaps throughout. In the assembly part, although there was no insert iron plate behind the molding part, the appearance was exactly the same, and there was no problem in operation.
［例２］

部長りを１０ｍｍとした以外は例１と同一に実施した。[Example 2] As shown in Fig. 2, the same extrusion molded product as in Example 1 was used, but one joint end of the extrusion molded part 1 was cut in steps only at the assembly part to form an extension part E. . That is, the same procedure as in Example 1 was carried out, except that the total length of the molded part 2 was 100 mm, E was set to 90 on, and the length of the molded part of the assembly part was set to 10 mm.

なかった。In Example 2, when a mold without the protruding edge 71 was used as the sealing part medium mold 7, Ro entered the solid sponge rubber as shown in FIG. 4. In this example, although E is 90+n+ and L is 10ma+, Ro reaches 811IIl, and the upper molded seal part 21 connected to the molded assembly part 22 extends to 8m+w of the connection part with the assembly part 22. Since it was made of solid rubber, it was given rigidity, which inhibited the sealing properties of sponge rubber as a sealing part, and the product was no longer able to exhibit a uniform sealing effect.
即ち、請求項１及び２に記載の好適なウェザ−ストリッ
