Title (EN) CLAMP HOUSING FOR INJECTION MOLDING HEATERS
(FR) LOGEMENT DE SERRAGE POUR DISPOSITIFS DE CHAUFFAGE MOULES PAR INJECTION
Abstract:
(EN) A clamp housing (11) for cylindrically wound heaters (12), particularly for an injection molding nozzle heater, has a slit (16) that permits changing the effective diameter of the housing (11) and it is actuated by an axially extending cam pin (40) that can be easily adjusted from an exposed end of the heater (12). The cam pin (40) has a central cam portion (42) formed between two end hubs (41) that are rotatably mounted with respect to one edge of the longitudinal slit (16) in the clamp housing (11). The central cam portion (42) that is mounted in a loop (30) formed from the opposite edge of the slit (16) in the housing (11). As the cam pin (40) is rotated the two edges of the slit (16) in the housing (11) can be forced together because of the cam action and the housing (11) will tighten around a heater (12) held on the interior of the clamp.
(FR) Un logement de serrage (11) pour des dispositifs de chauffage (12) à enroulage cylindrique, en particulier pour un dispositif de chauffage à ajutage de moulage par injection, possède une fente (16) qui permet de changer le diamètre effectif du logement (11) et est actionné par une goupille de came s'étendant axialement (40) qui peut être réglée facilement depuis une extrémité exposée du dispositif de chauffage (12). La goupille de came (40) possède une partie centrale de came (42) formée entre deux moyeux extrêmes (41) qui sont montés rotatifs par rapport à un bord de la fente longitudinale (16) dans le logement (11). La partie de came centrale (42) est montée dans une boucle (30) formée depuis le bord opposé de la fente (16) dans le logement (11). Lorsque la goupille de came (40) tourne, les deux bords de la fente (16) dans le logement (11) peuvent être serrés par l'action de came et le logement (11) se serre autour du dispositif de chauffage (12) maintenu à l'intérieur du logement de serrage.
