Method for transferring bottom labels and wraparound labels into an injection mould and device, suitable for this purpose, for producing injection-moulded parts provided with bottom labels and wraparound labels
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; andextracting 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.
PLASTIC COVER LENS AND DISPLAY FOR VEHICLE INCLUDING THE SAME
Disclosed is a display for a vehicle including a plastic cover lens including a lens, a front film disposed on a front surface of the lens, and a rear film disposed on a rear surface of the lens, a super retardation film (SRF) adhered to a rear surface of the plastic cover lens using an optically clear adhesive (OCA), a liquid crystal display module adhered to a rear surface of the super retardation film using the optically clear adhesive, a panel-front assembled at the rear of the plastic cover lens, in close contact with and supporting the liquid crystal display module, and preventing deformation of the plastic cover lens, and a rear cover assembled at the rear of the panel-front.
In-mold label forming surfaces for molded articles
A method of making a molded article having a curved surface, such as plates or serving trays, and the resulting molded articles. The in-mold label (IML) is a laminated film that includes a backing layer, a printed surface incorporating one or more designs thereon, a protective film layer, and one or more notches each having adjacent edges separated by a gap of predetermined distance and configured to intersect to ensure conformance of the IML to the angled or curved peripheral portion of the article. The article has front and back sides and a central portion bounded by a peripheral portion having a perimeter that is raised on the front side of the article wherein the peripheral portion transitions from the perimeter to the central portion by an angled surface, a curved surface or combinations thereof, with the article including the IML at least peripheral portion of the molded article.
Method and system for producing an injection moulded product and a label transfer device
In an injection mould, a plastic injection-moulded product is manufactured. The plastic injection-moulded product comprises a tubular body, a neck part and a head part. The injection mould comprises three mould parts, which are displaceable with respect to each other between a closed position and an open position. The first mould part comprises a first mould cavity for producing the neck part and the head part. The second mould part comprises a second mould cavity for producing the tubular body. The third mould part comprises a core body. In the open position, a neck label is arranged in the first mould cavity of the first mould part and a peripheral label is arranged in the second mould part. Subsequently, the mould parts are moved to the closed position to form a closed mould cavity. By supplying plastic, the plastic injection-moulded product is produced. The labels are integrally formed in the plastic injection-moulded product (in-mould labelling).
METHOD FOR TRANSFERRING BOTTOM LABELS AND WRAPAROUND LABELS INTO AN INJECTION MOULD AND DEVICE, SUITABLE FOR THIS PURPOSE, FOR PRODUCING INJECTION-MOULDED PARTS PROVIDED WITH BOTTOM LABELS AND WRAPAROUND LABELS
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; andextracting 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.
