Abstract: A foil-decorating injection molding apparatus 1 comprises a male mold 20 and a female mold 2, a transport chuck 30 for feeding a decorative sheet S between the male mold 20 and the female mold 2, and a damper 10 for pressing and fastening the decorative sheet S onto a parting surface 2a of the female mold 2. The transport chuck 30 consists of two clamping devices 31 each clamping the side edge on either side of the decorative sheet S. The damper 10 consists of a pressing frame 11 and a connecting member 12 and is formed in a shape such that, even when the pressing frame 11 is in abutment with the female mold 2, there is established a space between the connecting member 12 and the female mold 2 in which the clamping devices 31 can pass through. After the decorative sheet S is fed by the clamping chuck 30, the sheet S can be fastened by the damper 10 without having to wait until the chuck 30 is brought back to an initial standby position, thereby reducing the manufacturing time.

Abstract: In the method, after the pattern-bearing film is fed to the female mold, the distal end of the film is fixed under a lower portion of the female mold, and at the same time the film is retreated by a force from the film supply portion. Thus, this tightens up the film so that the slacks or wrinkles cannot be formed on the film. Therefore, the film can be fortunately spread around the parting surface of the female mold. In the apparatus, the film suppressing frame is pressed to the female mold through the sliding rod arranged in the female mold, in such a manner that the female mold embraces the frame. Thus, the pressing of the frame is performed by a simple structure, and the film is accurately positioned to the internal surface of the female mold. Also, the film suppressing frame is constituted to advance from and retreat to the female mold. Thus, this causes a space between the both molds and an outside standby position to be useless. A space around the apparatus can be effectively utilized.

Abstract: A foil-decorating injection molding method and a foil-decorating injection molding apparatus adjust the tautness of a decorative sheet fed onto a parting surface of a female mold so that tensions T1, T2 and T3 of the decorative sheet during a sheet feed operation of the sheet feed means, at the start of the sheet clamping operation of the clamper for pressing and fixing the decorative sheet and at a moment immediately before the completion of the sheet clamping operation, respectively, meet an inequality: T1≧T2>T3 to prevent the decorative sheet from breaking or slipping off the clamper when clamping the decorative sheet on the parting surface of the female mold.

Abstract: A sheet-decorating injection molding machine (10) comprises: a female mold (12) having a hollow (13) and a parting surface (14) surrounding the hollow (13); a male mold (25) disposed opposite to the female mold (12) to hold a decorative sheet (S) between the female and the male mold (12, 25) and provided with runners (27) and gates (28) through which a molten resin is injected into a cavity defined by the female mold (12) and the male mold (25). The parting surface (14) of the female mold (12) includes a substantially convex, curved surface. A sheet feed mechanism (5) comprises a driving-and-guiding mechanism including sprocket wheels (41, 42, 43, 44, 45) and a stepping geared motor (52).

Abstract: A decoration sheet is retained on the cavity periphery by a sheet clamp in such a state that it is projected into a molding cavity of a female die. Then the decoration sheet is heated and softened by a curved hot platen, and thereafter it is drawn through suction ports of the female die to bring the sheet into close fit to the inner periphery of the molding cavity. The deformation amount of the decoration sheet heated and softened is decreased in premolding the sheet into the molding cavity surface of the female die. Therefore, distortion of the decoration sheet, appearance of wrinkles, and breakage thereof become little. Next, the female die and the male die are coupled with each other to effect die clamping, and a molten resin is poured to fill the molding cavity to effect injection molding.
