Threaded core unscrewing device for unscrewing threaded core from injection molding tool, has driving motor arranged laterally beside threaded core screw nut, where motor is hydraulic motor or electrical step or linear motor

摘要

The device has a threaded core screw nut (1) i.e. metallic pipe, with a guiding thread (23), where the nut is arranged between a mounting flange (3) and a base plate (4). A threaded core holder (2) is rotatably guided with a drive screw (5) in the nut. The nut is screwed together with the plate and the flange. The screw has a drive shaft (6) fixed to a drive wheel (7) and comprising an axial bearing surface (27) that extends into one- or multi-part telescopic tube (8). A driving motor (9) is arranged laterally beside the nut, where motor is hydraulic motor or electrical step or linear motor.
