There is something. The base sheet is a film-like material such as polyethylene terephthalate or polypropylene. The release layer is a resin layer that provides releasability between the base sheet and the decorative layer. The decorative layer is a layer that imparts decorativeness and functionality to the surface of the molded product. The decorative layer includes a pattern, a pattern made of printing ink such as characters and symbols, and a conductive pattern formed of a conductive material. If necessary, it may have a metal deposition layer. The adhesive layer is a resin layer for bonding the decorative layer and the molded product 4. After the decorative sheet 2 is adhered to the surface of the molded article 4, the base sheet is peeled off, and only the transfer layer is transferred to the surface of the molded article 4.

Is injected and filled (see FIG. 4). By filling the cavity 7 with the molten resin 61, the decorative sheet 2 is pressed against the surface of the cavity 13.
【００２７】つぎに、溶融樹脂６１の射出後、溶融樹脂

ト２あるいは、転写層が形成される。The decorative sheet 2 is brought into close contact with the surface of the cavity 13 of the mold A11 due to the injection pressure of the molten resin 61 and the pressure of the pressurized gas injected into the molded product. Then, simultaneously with the molding, the decorative sheet 2 or the transfer layer is formed on the surface of the molded article.

い。The pressurized gas pushes through the inside of the molded article 4 and selectively enters the thick molded article corner 41 which is slow in cooling and has low viscosity. The pressurized gas that has entered generates an internal pressure toward the surface of the mold. By being supported by the internal pressure force of the pressurized gas, volume shrinkage due to cooling of the thick molded product corner 41 is suppressed. For this reason, the surface of the molded product does not dent, and the formation positions of the transfer layer and the decorative sheet 2 do not shift.

品を冷却するようにした。According to the method for manufacturing a decorative molded product and the decorative molding apparatus of the present invention, the decorative sheet is pushed into the cavity by the mold B in which the corners of the convex portions do not exhibit an acute angle, and the decorative sheet is melted. After the injection of the resin, pressurized gas was injected into the corners of the thick molded product formed by the corners of the protrusions of the mold B, and the molded product was cooled.

りせずきれいな加飾成形品が得られる。Therefore, it is possible to provide a transfer layer or a decorative sheet without wrinkles or damages at the corners of the molded product, and no sink marks are formed at the corners of the thick molded product. Therefore, a beautiful decorative molded product can be obtained without denting the surface of the molded product or shifting the formation positions of the transfer layer and the decorative sheet.
【００３３】また、加飾シートをキャビティ内表面に密
