Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is mounted on a vehicle such as an automobile, a train, a ship, an airplane, a glider, and a helicopter (in the present invention, the vehicle is defined as above), and is used as a side visor, an air dam, a roof visor, and a rear spoiler. The present invention relates to a method and an apparatus for forming an extrusion molded article for a vehicle, which is configured as a vehicle mounting member used as an air flow control member such as the above and a molding member such as a side molding and a bonnet molding.

2. Description of the Related Art Generally, a vehicle mounting member of this type is made of a hard material such as acrylic, which is made of metal or injection-molded, and is used for controlling lift during running of the vehicle and for controlling air flow to the lower side of the vehicle. It is used to control running stability and to improve ventilation inside and outside the vehicle, as well as shade and rain, and other decorative members of the vehicle in various shapes. The mounting member is required to have a special shape in order to reduce running resistance as much as possible.

In order to obtain a shape that reduces the running resistance,
For example, Japanese Patent Publication No. 5-19903 discloses a conventional technique for molding a molded article of this type having a modified cross section. The forming method described in the publication includes a step of continuously forming a metal strip having a constant width to form a metal profile having a constant cross-sectional shape and a fixed width portion and a variable width portion,
Extruding a metal profile through an extrusion mold to form a resin part with a constant cross-sectional shape in at least a fixed width part by extrusion molding, cutting the obtained molding material into a predetermined length, and a fixed width. And a step of bending the part to be the variable width part along the longitudinal direction so as to change the distance in the width direction from the part to form the variable width part.

That is, in Japanese Patent Publication No. 5-19903, the resin molding having a constant cross section is extruded and molded into a predetermined length, and then the length in the width direction is changed. The variable width part is formed by bending along the direction to form a molding with an irregular cross section.

[0005]

However, in such a conventional method of manufacturing a molding in which the modified cross-section is varied (Japanese Patent Publication No. 5-19903), the variable width portion is simply fixed at a constant angle ( There is no problem with those that can be plastically deformed by bending at a substantially right angle), but as will be described later, the bending angle is gradually increased and the angle can be changed, and it can be held without damaging the shape of the product. There is a problem that we can not respond if it is necessary.

Further, since the one described in the publication is plastically deformed by the above-mentioned bending, it cannot be bent again to fit another vehicle having a different shape after being bent once. There is a problem that a large number of types must be manufactured according to the shape of the vehicle. On the other hand, in the case of the injection-molded acrylic, the material is hard, so the shape of the product is not damaged,
Since post-processing after injection molding cannot be performed, there is also a problem that a large number of types must be manufactured according to the shapes of many vehicles so that a finished product can be produced at the time of injection molding.

The present invention was devised in view of the above problems, and at least includes a base portion and an exterior surface portion which are mutually connected through a connecting portion and a connecting portion which are separated from each other by the extrusion molding process. Extruding a basic molded body having a different cross-section, and then post-processing the same basic molded body in a modified cross-section molding process, at least a part of the connecting portion is expanded and contracted according to the specifications to be deformed. Accordingly, it is an object of the present invention to provide a molding method and apparatus for the same molded body which has a low cost and can be molded into a desired irregular cross section, and has general versatility.
