Abstract
(EN)
The invention relates to an injection moulding device. A heating sleeve (63) is arranged around the injection nozzle (19) with failsafe means (71, 109) that do not permit the above to reach an operating position in which electrical contact is established between the electrical conducting pads on said sleeve (63) and contact blades (107) connected to a controlled power supply except when in a given orientation. Of application to simplifying assembly and electrical connection.

(FR)
La présente invention concerne un dispositif d' inj ection-moulage . Autour de la buse d'injection (19) est disposé un manchon de chauffage (63) auquel des moyens de détrompage (71, 109) ne permettent d'atteindre qu'à la condition qu'il présente une orientation déterminée une position de service dans laquelle s'établissent des contacts électriques entre des plages électriquement conductrices de ce manchon (63) et des lames de contact (107) reliées à des moyens d'alimentation électrique commandée. Application à la simplification du montage et de la connexion électrique.
