A method is proposed for transferring a bottom label and a wraparound label into an injection mould for producing an injection-moulded part provided with the labels, in that the bottom label is arranged on the end side and the wraparound label on the lateral side of an insert die and the insert die equipped with the two labels is introduced into the mould cavity of the moulding tool, after which the bottom label is deposited on the bottom and the wraparound label on the lateral surface of the mould cavity of the moulding tool, in order to back-mould them with a plastics material injected into the mould cavity. According to the invention, the method comprises the following steps of:—providing an insert die, the end side of which has a central portion and a circumferential portion adjoining the central portion radially on the outside, wherein the central portion protrudes further in the direction of the free end of the insert die in the axial direction of the latter than the circumferential portion, such that the cross section of the insert die narrows in the direction of its free end, at least in the circumferential portion of its end side;—applying the bottom label both to the central portion and to the circumferential portion of the end side of the insert die and applying the wraparound label to the lateral side thereof such that the wraparound label projects beyond the end, fining the end side, of the lateral side of the insert die in the direction of the free end thereof;—introducing the insert die equipped with the two labels into the mould cavity of the moulding tool;—detaching the wraparound label from the lateral side of the insert die and applying same at least to the lateral surface of the mould cavity of the moulding tool;—detaching the bottom label from the end side of the insert die and applying same to the bottom of the mould cavity of the moulding tool, wherein the peripheral region of the bottom label is turned down from the circumferential portion of the end side of the insert die onto the bottom of the mould cavity of the moulding tool, such that it internally overlaps the edge, facing it, of the wraparound label; and—extracting the insert die from the mould cavity of the moulding tool. The invention also relates to an injection-moulding device, suitable for carrying out such a method, having an insert die of the abovementioned type.
A method for transferring a bottom label (2) and a wraparound label (3) into an injection mold (4) for producing an injection molded part provided with the bottom label (2) and with the wraparound label (3), in particular in the form of a container, in that the bottom label (2) is arranged on the end side (10) of an insert die (1) and the wraparound label (3) on the lateral side (11) of the insert die (1), and the insert die (1) equipped with both the bottom label (2) and with the wraparound label (3) is introduced into a mold cavity of a molding tool (4), after which the bottom label (2) is deposited on the bottom (4a) of the mold cavity of the molding tool (4) and the wraparound label (3) is deposited on the lateral surface (4b) of the mold cavity of the molding tool (4) in order to back-mold them with a plastics material, characterized by the following steps:
