この考案は内部に発泡部分を形成させたクツシ

つていた。 In recent years, side moldings used in automobiles have tended to become larger, and in order to avoid the weight increase due to larger sizes, they have been made hollow or made of foam (with a foaming rate of 2 times or less). However, even if the inside is made hollow, a certain degree of hardness and strength is required, and there are restrictions on the material and shape, so an increase in weight is unavoidable. Since the foam and other parts are extruded at the same time, the foaming ratio can only be 2 times or less, resulting in an increase in weight.

As described in Publication No. 26025, it consists of a skin made of soft synthetic resin, a cushion body made of a foamed material, and a base that is harder than the skin and bent at a predetermined angle depending on where it is attached. There is a structure in which the ends are welded to both side ends of the base via a cushion body compressed at the ends, and the cushion body is wrapped between the skin and the base.
しかしながら、このようなモールを大型モール
に適用した場合、圧縮されたクツシヨン体の復元
作用によりモール表面が波打つ問題が懸念される
とともに、モールの巾方向両側に溶着部分が残る
ため意匠性が劣るという問題があつた。 However, when such a molding is applied to a large molding, there is a concern that the surface of the molding may wave due to the restoring action of the compressed cushion body, and the design is inferior because welded parts remain on both sides of the width of the molding. There was a problem.
この考案は上記にかんがみ、重量が軽減され、

It has a synthetic resin molding.

As shown in the cross-sectional view of FIG. 1, a band 2 made of a synthetic resin foam such as polyethylene, polypropylene, or modified polypropylene having an expansion ratio of 5 times or more is heated and compressed into a predetermined shape for preforming. After being plastically deformed, a coating layer 3 is formed on the outer surface of the band 2 using a non-foamable synthetic resin such as soft vinyl chloride. In addition, the foaming ratio of the band 2 needs to be 5 times or more in order to reduce the weight increase due to the enlargement of the automobile side molding 1, but in consideration of moldability etc., it is preferable to set the foaming ratio to 5 to 15 times. . Further, the thickness of the coating layer 3 is preferably about 1 to 2 mm. The side molding 1 having cushioning properties is attached with double-sided adhesive tape (not shown) at the bottom.

３を押出すようにすればよい。 As shown in Fig. 2, the manufacturing method of the side molding 1 with cushioning properties of this invention is as shown in Fig. 2, in order to first preform the band 2, a material such as polyethylene having a foaming ratio of 5 times or more is made by a known manufacturing method. After heating the band 2 made of synthetic resin foam with the heating device 4,
It is compressed by a molding roll 5 and plastically deformed into a predetermined shape. Next, this strip 2 is passed through an extruder 6 and a die 7
A synthetic resin coating layer 8 such as vinyl chloride or the like is formed on the surface of the strip 2 and extruded, and after cooling, the strip is transferred to a take-off machine and cut to a predetermined size using a cutter to obtain the side molding 1. In addition, the band 2 and the coating layer 3
If you want to firmly adhere the
After coating the surface of the adhesive with the adhesive, the coating layer 3 may be extruded onto the surface.

樹脂製モールを得ることができる。 Since this invention has the above-mentioned structure, the specific gravity of the synthetic resin molding is less than half that of the conventional synthetic resin molding having an internal hollow shape or internal foaming, and the specific gravity is reduced. In addition, since the band has a foaming ratio of 5 times or more, it feels soft when it comes in contact with the body, and has excellent feeling.Since the band is made of plastically deformed synthetic resin foam, the restoring effect of the foam is almost negligible. Even when applied to large moldings, no waving phenomenon appears on the surface of the molding, and a synthetic resin molding with excellent aesthetic appearance can be obtained.
