    Abstract: A multi-functional mould which is used for encapsulating chips placed on lead frames is characterized by a chamber (15) arranged in one of the mould halves (5, 6) in which an aggregate can be replaceably arranged. Depending on the use of the mould in the context of the so-called transfer method or in an injection moulding method a different aggregate (16, 19) is placed in the chamber (15). In the application as transfer mould the aggregate consists of an elongate member (16) with a bore (17) for guiding a plunger (7), which makes encapsulating material liquid due to the pressure applied thereto and the increase in temperature. In the application as injection mould the aggregate contains a member (19) with a through-channel (22) for a plasticized encapsulating material coming from the nozzle (13) of the injection moulding device.

    Abstract: A cold runner block (38) has spaced drop holes (54) arranged in a selected pattern for supplying fluid molding material to nozzles (60) con­nected to the mold gates (62). The drop holes (54) open on nozzle runners (52) in the cold runner block (38) which are in communication with a source of fluid molding material. Close-off rods (68) are selectively positioned in the runners (52) to block the flow of fluid molding material beyond the drop holes (54) communicating with a mold (12) for an object of a particular size and shape. Drop hole plugs (66) are provided for the drop holes (54) which open on the nozzle runners (52) in the section of the runners (52) not blocked by the close-off rods (68).

    Abstract: Eine Kugelkette wird in der Weise aus Kunststoff in einem Spritzgusswerkzeug (18, 20) hergestellt. dass eine Mehrzahl von auf einer Kordel (3) aufgereihten Kugeln gleichzeitig gespritzt werden. Die Hohlräume (8) im Spritzwerkzeug zur Bildung der Kugeln stehen je mit Seitenkanälen (10) in Verbindung und münden in einen gemeinsamen Einspritzhohlraum (12). Unmittelbar am Übergang von den Seitenkanälen (10) zum Hohlraum (8) ist eine Verengung (14) des Querschnittes vorhanden. Dadurch wird verhindert, dass sich beim Erkalten der Schwund des im länglichen Einspritzhohlraum (12) befindlichen Materials auf die Kugeln übertragen kann und sich dadurch Teilungsfehler ergeben.

    Abstract: A production runner mold is disclosed which has a movable mold part (302; 402; 502) and a stationary mold part (303; 403; 503) defining a mold cavity (304; 404; 504). Opening on the mold to release a molded product defines a mold opening direction. The stationary mold part is separable into first and second sections (307; 407; 517; 308; 408; 518), the first section including a primary runner (310; 410; 509) and the second section including secondary runners (311; 411; 511). The secondary runners are inclined to the mold opening direction to improve the properties of the molded product. If for some reason the normal production cycle is terminated such that the molten plastic within the inclined secondary runners transfers additional heat to the walls of the inclined secondary runners whereby the molten plastic solidifies throughout its entire cross-sectional region, the normal production cycle may hereafter be re-established by the steps of:

    (h) separating the mold part which contains the inclined secondary runners into its two sections in order to expose the solidified impressions of the inclined secondary runners,
    (i) removing the solidified impressions of the inclined secondary runners in such a manner that the impressions of the restriction gate on the solidified impressions of the inclined secondary runners are removed through the inclined secondary runner in a direction which is not parallel to the mold opening direction; and
    (j) recombining the two sections of the mold part which contain the inclined secondary runners.

    Abstract: The present Invention relates to a position adjusting means for hot runner nozzles comprising a main inlet, a manifold, a rotational transitional piece and a nozzle; the rotating transitional member is disposed with an Inlet and an outlet; the inlet and the outlet of the rotating transitional member each has a symmetry axis and the two symmetry axes are disposed in parallel with and spaced apart from each other for a particular distance; the inlet of the rotating transitional member and the outlet of the manifold are connected to each other in a rotatable and sealed manner; the outlet of the rotating transitional member and the inlet of the nozzle are connected to each other in a rotatable and sealed manner; the nozzle or a nozzle assembly formed by the nozzle and a nozzle extension member of the nozzle combining together is disposed with an inlet and an outlet; the inlet and the outlet of the nozzle or the nozzle assembly each has a symmetry axis and the two symmetry axes are disposed in parallel with and spaced apart from each other for a particular distance. With the symmetry axis of the inlet of the nozzle or the rotating transitional member as circle center, rotate either one of the rotating transitional member or the nozzle or rotate both the rotating transitional member and the nozzle to position the outlet of the nozzle at a desired position within a particular area, thereby attaining adjustment of the position of the hot runner nozzle. The present invention may be applied to hot runner systems of plastics injection molding.
