    摘要： Bei einem Spritzgussverfahren zur wahlweisen Herstellung von Formteilen (7) mit und ohne Durchbruch (8), wird
    - ein Spritzgusswerkzeug (1a, 1 b) verwendet, welches mindestens einen von wenigstens einer düsenseitigen und wenigstens einer auswerferseitigen Werkzeugplatte (2, 3) umgrenzten Formhohlraum (4) und einen im Formhohlraum (4) zumindest teilweise positionierbaren, gegenüber mindestens einer der Werkzeugplatten (2, 3), insbesondere der düsenseitigen Werkzeugplatte (3), in einer Vor- und Rückschubrichtung (14, 15) relativ beweglichen Formkern (10, 17) aufweist, wobei dieser bei einer Bewegung in Vorschubrichtung (14) der jeweils anderen Werkzeugplatte (2, 3), insbesondere der düsenseitigen Werkzeugplatte (3), angenähert wird und sich bei einer Bewegung in Rückschubrichtung (15) von dieser entfernt,
    - zur Herstellung eines Formteils (7) mit Durchbruch (8) der Formkern (10, 17) im Formhohlraum (4) positioniert, und bei der Herstellung eines Formteils (7') ohne Durchbruch wird der Formkern (10, 17) zumindest teilweise aus dem Formhohlraum (4) entfernt. Es ist mindestens eine Schutzmaßnahme vorgesehen, mit der die zum Formhohlraum weisende Innenfläche (24) der jeweiligem insbesondere anderen, bevorzugt düsenseitigen, Werkzeugplatte (3) vor einer mechanischen Beeinträchtigung bei einer Vorschubbewegung des Formkerns (10, 17) geschützt wird.

    摘要： The invention is directed to a method and an apparatus for the production of three- dimensionally thin products using injection moulding of polymer based material. By dividing one of the mould halves in at least two groups of elements, whereby at least a first group of at least one element forms a rim cavity and a stop, defined as an area of the element contacting the other halve if the mould is in the closed position, and at least a second group of at least one element forms the main body part of the cavity, whereby all the elements together form with the other mould halve one cavity, and whereby each of the groups of elements is connected to its own means for clamping, it is possible to produce a set of different products with a constant rim thickness and a variable thicknes of the main body part of the product.

    摘要： A mold set is installed that consists of a male mold and a female mold having on its inner surface side a predetermined embossing pattern and predetermined vacuum suction fine holes. A vacuum suction mechanism for feeding a vacuum pressure to the vacuum suction fine holes comprises a receiving hole disposed at right angles with the reference plane for the mold with its front end extending toward the inner surface of the female mold over a distance less a predetermine distance, and having a predetermined diameter, and vacuum suction fine holes linearly extending from adjacent the front end of the receiving hole toward the inner surface of the female mold and consisting of a hole disposed at plane right angles with the inner surface of the female mold, holes radially disposed around the hole disposed at plane right angles, and so on. A spacer for controlling the cavity space to a suitable volume is installed at a guide pin along which the female and male molds slide-wise engage each other.

    摘要： Method and apparatus for lens thickness adjustment in injection molding of thermoplastic vison-corrective spectacle lenses without manual addition or removal of shims, of inserts or of any other mold part. Thickness adjustment can be made quickly while the lens mold is kept at very hot operating temperatures, yet minimal risk of burning the operator. A rotatable adjustment head (11) is mounted externally onto the mold's operator side, and manually-driven rotation turns a threaded screw (10) which moves one wedge block (7) of a slideably mated pair of opposing wedge blocks in a plane parallel to the parting line (4-4), thus moving the opposing wedge block (6) axially forward or back (20) perpendicular to the parting line, but always retaining proper alignment and loadbearing support of optical inserts, even in multicavity injection-compression molding. After many re-polishings of inserts, lens thickness specifications are still maintained without needing shims. This permits use of circulating heat transfer fluids internally (29) within the inserts (4 and 5), to greatly reduce cycle times, yet have minimal fluid leakage problems.

    摘要： A molding die for molding a magnetic tape cartridge case in which an electronic part for exchanging a signal with the outside via contacts is incorporated as the need arises is such that a molding die portion for use in molding openings for exposing the contacts of the electronic part is constituted of two kinds of inserts which are alternatively attachable to the molding die proper; and a first insert is used to form openings for exposing the contacts, whereas a second insert is used to shut the openings for exposing the contacts.
