Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for extruding a long member such as a window molding mounted on a peripheral portion of a window plate of an automobile.

[0002]

2. Description of the Related Art Generally, elongated members are used in various fields. For example, a window molding having a sealing function and a decorative function is attached to a peripheral portion of a window plate (hereinafter, referred to as a window glass for easy understanding) attached to a window opening of a vehicle body panel of an automobile. I have. Specifically, an elongated gap is continuously formed between the periphery of the window glass and the window frame opening of the vehicle body panel, and a window molding made of an elongated extrusion member is formed in the gap. Is inserted and sealing is performed. This wind molding has a leg portion inserted into the gap and a decorative portion that covers the gap from the outside of the vehicle.

[0003] On the other hand, such window moldings for automobiles are often provided with grooves such as rainwater gutters. For example, in Japanese Patent Publication No. 51-35727, a projecting portion constituting a water collecting groove is integrally formed in a molding frame covering a fixing portion of a window glass.

[0004] However, the conventional molding in which the cross-sectional shape is extruded in a fixed shape has limitations in the following points. For example, if the step between the vehicle body panel and the window plate is continuously changing, the cross-sectional shape of the molding will be in an inconsistent state due to the change in the step, so that it can be attached and decorated. Cause problems in sex. Also, when moldings having different functions are required at the corners, for example, when the upper part is provided with a flash surface and the side part is provided with a gutter function for rainwater, the cross-sectional shape is different. It is usual to prepare various types of molding and attach each to the corresponding part, but in that case, the terminal part of the cut member may be visible from the outside, in order to avoid this, A connection member such as a corner joint is often employed.

[0005] For these reasons, it is desirable that the cross-sectional shape of the entire length of the wind molding, particularly the cross-sectional shape of the rainwater gutter, be varied depending on the location. For example, in Japanese Unexamined Patent Publication No. 62-289427, the size of the gutter for rainwater is changed in the longitudinal direction by combining a plurality of components. Further, Japanese Unexamined Patent Application Publication No. 1-195032
JP, JP-A 1-244820, JP-A 1-2
In Japanese Patent No. 69612, the cross-sectional shape of the extruded product is changed in the longitudinal direction by cutting off a part of the product immediately after extrusion of the molding. Furthermore, Japanese Patent Laid-Open No.
In the structure described in Japanese Patent No. 269611, extruded articles formed through different extrusion openings are united immediately after extrusion.

[0006]

However, in the above-mentioned conventional wind molding, the water blocking function and the water receiving capacity of the rainwater gutter may not be sufficient, and there are various problems relating to the manufacturing method and apparatus. .
For example, Japanese Unexamined Patent Publication No. 62-289427 requires a process of manufacturing and combining a plurality of parts.
Productivity is extremely poor.

Furthermore, in extrusion molding, generally, it is desirable to form a substantially parallel die land portion by a molding surface facing in the vicinity of the extrusion molding port.
Surface morphology and shape accuracy are improved. In that respect, Japanese Patent Laid-Open No. 1-1
Japanese Unexamined Patent Publication No. 95032 discloses a problem that the surface state of the cutout (15a) is difficult, and a difference from the surface state of other decorative surfaces occurs. Further, Japanese Patent Laid-Open No. 1-2
No. 69611 discloses a technique for synchronizing, and at the same time, no perfect technique has been disclosed yet, such as a problem of reliability in joining the support pieces extruded separately. It is.

The protrusion 22c narrows the groove width at the opening side of the rain gutter 29 in the in-vehicle direction, and the groove width at the bottom side of the rain gutter 29 increases the groove width at the opening side. It has been expanded to the outside of the car.

The structure for mounting the wind molding 2 on the vehicle body will be described below. The inner peripheral edge of the glass mounting window opening provided in the roof panel 3 and the pillar panel 4 is bent stepwise toward the indoor side so as to receive the window glass 1, and the inclined walls 3a, 4 are provided.

The inner side surface (the lower surface in the figure) of the window glass 1 is brought into contact with the dam rubber 5 and pressed. As a result, the window glass 1 is fixed to the flange portions 3 and 4 on the vehicle body panels 3 and 4 at a substantially uniform height all around. A step and a gap corresponding to the rising height of the inclined walls 3a, 4a are formed between the outer surface of the window glass 1 and the surfaces of the vehicle body panels 3, 4.
