Abstract

PURPOSE:To prepare a hollow resin article rationally by a method wherein a leg part for engagement formed in a belt-shaped ornamental member is protruded into a cavity of a blow mold which has the cavity in a shape corresponding to the external shape of a molding. CONSTITUTION:An ornamental member 1 having a leg part 1a for engagement which is molded beforehand by extrusion molding or the like and has an enlarged end is fixed in a half 3 of a blow mold which has a cavity 3a in a shape corresponding to the external shape of molding M, in such a manner that the leg part 1a for engagement is protruded into the cavity 3a. Then, a parison 5 formed of hard vinyl chloride resin or the like is subjected to blow molding in a cavity formed by matching of the halves 3 and 4 of the blow mold, and thereby the molding M is formed.

Recently, wide and large moldings, such as those seen in the side moldings of automobiles, have come to be used in order to more effectively protect the surface of products. However, as the length of the molding increases, it becomes heavier, and the amount of raw material used increases. In order to eliminate these problems, hollow synthetic resin moldings have been proposed. That is, by making the inside of the molding hollow, it was attempted to reduce the weight and save the raw materials used. In addition to the above-mentioned effects, the hollow molding has an excellent buffering effect resulting from the hollow nitrogen shape, and therefore has a very high practical value.

飾部材を積場したものが殆どである。By the way, since a molding is attached to the surface of a product, its decorativeness is important even if the purpose is to protect the surface of the product. It was preferred to use a molding material in which decorative members such as synthetic resin strips were laminated on the surface of the molding base material to enhance the decorative effect. Moreover, most of the conventional moldings that have decorative members on the surface are those in which the decorative members are simultaneously extruded during extrusion molding of the mold base material, which is filled with material, and the decorative members are deposited on the surface of the mold base material. .

かった。However, hollow synthetic resin moldings are obtained by blow-molding a parison made of a thermoplastic synthetic resin in a hard vinyl chloride resin in the cavity of a blow-molding mold having a cavity shaped to correspond to the outer shape of the molding. Therefore, it was not easy to provide decorative members on the surface.
