Abstract

PURPOSE:To manufacture a stereoscopic decoration piece by pressing, heating, fusion-adhering and fusion-cutting a film by a high frequency induction heating mold having a fusion-cutter at a position corresponding to a design contour and a press-cutter at a position corresponding to a design contour corresponding to at least one profile of protrusions of a pressure receiving mold. CONSTITUTION:A pressure receiving mold 1 having a base made of an electric insulator and a plurality of protrusions protruding with steps corresponding to the swells of a design in a direction perpendicular to the surface to be processed of one electrode 12 for high frequency induction heating from the base is placed on the surface of the electrode 12. A hard thermoplastic synthetic resin sheet is superposed on the mold 1 and an extensible base sheet is superposed on the resin sheet. Then, a thermoplastic synthetic resin film is superposed on the base sheet, pressed, heated from above by a mold 12 having a fusion- cutter at a position corresponding to the contour of a design and a press-cutter at a position corresponding to the design contour corresponding to at least one profile of the protrusions of the pressure receiving mold, fusion-adhered, and fusion-cut to obtain a stereoscopic decoration piece 3.

熱可塑性合成樹脂シートで押圧されて低く膨隆し、押圧
による溶着部で囲まれた広い部位Ｋには、装飾片内に閉
じ込められた空気の圧力で高く膨隆されるものである。[Problems to be Solved by the Invention] When the decorative piece obtained by the above-mentioned conventional technique is shown in cross section, it has a structure as shown in FIG. 5, and the swelling is due to the bulkiness of the foam sheet of thermoplastic synthetic resin, The foaming is carried out by the air trapped inside the decorative piece, and the foaming is carried out in areas where the distance GH between the above-mentioned fusing blade part A, pressing blade part B, C, D, etc. is wide. In the area where the sheet I bulges highly due to the force of the sheet I, and the gaps G and H are narrow, the foamed sheet 1 is pressed by the thermoplastic synthetic resin sheet and swells low, and in the wide area K surrounded by the welded area due to the pressing, It is swollen high by the pressure of the air trapped inside the decorative piece.

しかし、これ等の膨隆は、発泡シートの嵩高さや内封さ

の立体を形成するごとき膨隆度合の著しく大きな装飾片
は形成できず、また保形性能は特に保有していないので
、成形完了時の扁平形態以外の形態を採らせても、直ち
に扁平形態に戻ってしまう等の点で問題が存する。However, these bulges only depend on the bulk of the foam sheet and the air pressure contained within it, so the degree of bulge is small. It is not possible to form a decorative piece with a significantly large degree of bulge, and it does not particularly have shape-retaining properties, so even if it takes a shape other than the flat shape upon completion of molding, it will immediately return to the flat shape. There is a problem in this respect.

The object of the present invention is to provide a method for molding a decorative piece made of a thermoplastic synthetic resin film that has a high ability to retain its three-dimensional shape, and a mold used for the molding.
