BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long molding to be attached to an object such as a vehicle or a ship, and a method for manufacturing the same.

0002

2. Description of the Related Art A molding that serves as a seal and decoration is attached to the peripheral edge of a window glass attached to a window opening of a vehicle body panel, such as a vehicle or a ship. More specifically, an elongated gap is continuously formed from the upper part to the side part between the peripheral end surface of the windshield and the opening edge of the window opening in the vehicle body panel. The gap is sealed and decorated by inserting an elongated molding body into the gap.

[0003] Moldings that are continuously attached to different parts of the object to be attached are often formed into a long shape by extrusion, but general moldings are made by forming a strip on the outer surface of the object to be attached. The device includes a decorative portion that covers the decorative portion, and a mounting portion that protrudes from the back side of the decorative portion toward the back side of the object to be attached and is fitted onto the object to be attached.

[0004] When manufacturing moldings to be attached to different parts of the object to be attached, first, a plurality of molding bodies each having a shape corresponding to the different parts of the object to be attached are separately extruded, and each of them is Generally, molding bodies are connected in an elongated manner via a joint member or the like. However, such moldings consisting of a connecting structure of a plurality of molding bodies have various problems in terms of decoration or function. Therefore, conventionally, for example, Japanese Patent Application Laid-Open No. 63-291721 or Japanese Patent Application Laid-Open No. 1-2
No. 44820, etc., proposes a method in which a molding having a certain basic shape is first extruded in a series, and then a part of the molding is cut out to remove unnecessary parts.

[0005]

[Problems to be Solved by the Invention] However, in such conventional molding, the molding shape is limited to the shape that can be formed by cutting, and there is a limit to moldability, and the cross-sectional structure of the part that is not cut is changed. It is not possible to perform molding that would cause For example, a molding in which a decorative part extending in a band shape on the outer surface of an object to be attached and a mounting part fitted to the object to be attached are separately changed in shape cannot be made by the above-mentioned cutting process. Cannot be molded. In other words, conventional moldings do not yet have sufficient adaptability for attachment to different parts of the attachment target.

On the other hand, Japanese Patent Laid-Open No. 62-234814 and others propose a molding in which the shape of the molding is changed in appearance by adding other parts. According to this method, it is possible to mold shapes that cannot be molded by the cutting process, but there are limits to the shape, and the manufacturing and assembly processes increase due to the addition of parts. There is a problem in that this leads to a decrease in productivity.

[0007] Furthermore, when a core material is provided in the molding, the core material is usually provided over the entire length of the molding. Therefore, in this case, the shape of the entire molding will be molded to form a plastic shape that follows the shape of the object to which it is attached, making it difficult to attach it to the object and also making it difficult to mold. However, there are problems in that a large mold is required and a large space is also required for storing and transporting the molding.

SUMMARY OF THE INVENTION Therefore, the present invention provides a molding that is highly adaptable to attachment to different parts of an object, and allows such a molding to be formed continuously and efficiently using simple means.

At this time, the feed amount of the insert material 9 detected by the detection device 13 is applied to the control device 21, and the extrusion mold device 16 is controlled based on the input signal.
The operation timing of the cutting device 19 is determined, and an operation signal is output from the control device 21 to each device 16 and 19. Note that the detection device 13 may be placed anywhere as long as it can detect the amount of progress or movement of the material; for example, it can be placed either before or before the take-up machine 18.

As shown in FIG. 7, the molding die installed in the extrusion die device 16 first includes a first die 161 and a first die 161 arranged in parallel in the extrusion direction of the molding (perpendicular to the paper surface). , a second die 162, and a third die 163. The second die 162 is installed in a fixed state and includes an extrusion forming opening 162a. This extrusion forming port 162a has an opening portion having an outline shape corresponding to the attachment portion of the side molding portion 5B described above, and an opening portion having an outline shape that extends the decorative portion upward in the drawing.

The first die 161 and the third die 163 are each formed from a plate-like member, and each has a pair of guides 164, 164 and 165 on the front surface of the second die 162. , 165 so as to be movable in parallel.

Further, a fixing hole 25B5 is formed through the mounting portion 25B2, and a door panel 26 is arranged at a predetermined distance on the outside of the mounting portion 25B2.

Next, as shown in FIGS. 12, 13 and 15, the corner molding part 25C has a decorative part 25C1 which is continuous from the windside molding part 25B with the same cross-sectional shape, and The decoration part 2
On the back side of 5C1, a separately molded attachment part 25C2 for attaching a corner part is provided, and is fixed to the panel side with adhesive 27. The inner wall surface of the decorative portion 25C1 is pressed against the end surface of the upper molding portion 5A. Note that this mounting portion 25C2 has a corner molding portion 2.
There is no function to actively fix 5C to the panel side, and its main function is to cover the gap at the corner. Furthermore, no metal core metal is embedded in the corner molding portion 25C.

Furthermore, as shown in FIGS. 12, 13 and 16, the side roof molding portion 25A is fitted into the long groove formed between the side panel 28 and the roof panel 1. There is. On the back side of the decorative part 25A1,

The molding 25 which has different cross-sectional shapes in the longitudinal direction and in which the metal core metal is partially embedded has the same functions and functions as the molding 5 according to the first embodiment described above. It is effective and can be similarly molded by the manufacturing method described above.

Effects of the Invention As described above, the molding according to the present invention maintains the decorative part of the same shape over different parts of the object to which it is to be attached, while also allowing the mounting part to have a shape that perfectly corresponds to the different parts of the object to which it is attached. This makes it possible to attach the molding extremely easily and reliably. In addition, by using a molding in which a metal core material is embedded only in a part of the mounting portion, it is possible to bend the molding as appropriate during installation, storage, and transportation, thereby improving various workability and storage properties. Further, in the method for manufacturing a molding according to the present invention, a molding portion having a basic constant cross-sectional shape is first extruded in a basic extrusion step, and the cross-sectional shape is changed along the longitudinal direction in a subsequent variable extrusion step. The molding part is extruded, and a molding part with a constant cross-sectional shape different from the cross-sectional shape in the basic extrusion process is extruded by a split extrusion process, and unnecessary molding parts that are split-extruded by this split extrusion process are extruded. Since the portion is removed by the cutting process, the molding having the structure according to the present invention can be molded continuously and efficiently using a simple and small mold.
