摘要:
Die Erfindung betrifft einen Einsatz (1) für eine Spritzgießdüse (6) mit einem Einsatzkörper (2), in dem mindestens ein Strömungskanal (3) mit einer Eintrittsöffnung und einer Austrittsöffnung (4) ausgebildet ist, wobei der Einsatzkörper (2) einen Halsabschnitt (5), zum Verbinden mit der Spritzgießdüse (6), einen Endabschnitt (7), zum Einsetzen in eine Formkavität eines Formeinsatzes, aufweist. Zudem weist der Einsatzkörper (2) einen radial gegenüber dem Endabschnitt (7) vorstehenden Flansch (8) mit einer Anschlagfläche (9), die der Austrittsöffnung (4) zugewandt ist und einer Fläche (10), die der Eintrittsöffnung zugewandt ist, auf. Es ist vorgesehen, dass der Halsabschnitt (5) mindestens eine Dichtung (11) aufweist.
摘要:
An edge-gated injection molding apparatus (100) is disclosed having an injection manifold assembly (102) for distributing a melt stream of moldable material to a plurality of mold cavities (104) aligned on opposing sides of the injection manifold assembly. The injection manifold assembly includes a plurality of melt outlets with each melt outlet being in fluid communication with a respective mold cavity, and a plurality of biasing components (224, 1024) disposed along a centerline of the injection manifold assembly. A nozzle seal (244) is disposed between each injection manifold assembly (102) melt outlet and its corresponding mold cavity. Each biasing component (224, 1024) is disposed between a pair of melt outlets and corresponding nozzle seals (244) for biasing the melt outlets and nozzle seals (244) outward from the centerline of the injection manifold assembly (102) toward their respective mold cavities (104) and applying a preload thereto.
摘要:
The invention relates to a device for treating a fiber web, especially a device for applying treatment substance for treating a moving fiber web on at least one surface of the fiber web, which device comprises at least one nozzle (10) comprising a channel (11) for the treatment substance and a tip or end (13) of the nozzle (10) for providing a treatment substance flow (15) on the fiber web- The tip or end of the nozzle (10) of the device for treating a fiber web is provided with means (21, 22) for managing the temperature of the tip or end (13) of the nozzle (10) for preventing the adhering of the heated treating substance.

摘要:
The invention relates to a hot runner nozzle for the lateral spraying of plastic components, having a multi-part nozzle body with one of more tip elements (3, 3') that protrude in an outward manner on the peripheral surface of the nozzle body. Said hot runner nozzle is characterised in that said nozzle body has a nozzle body base section (2) provided with an axial side having at least one or several recesses (5, 14) that are arranged in a distributed manner on the axial side for arranging and for partially receiving the at least one tip element (3, 3') or the tip elements (3, 3') that are pressed with a nozzle body clamping disc section (6) onto the axial side of the nozzle body base section (2).
