The triggering device for needle closing equipment injection molding nozzle closing needle

摘要

The triggering device for needle closing equipment injection molding nozzle closure on the needle. The main illustration: Fig.1 a device actuator (10) for needles closing equipment injection molding nozzle closure element has a lift (20) which can be fixed at least two needles of closure (16) of two nozzles of closure on the needle and is movable between two rulers of Coman (30), located in a first direction displaceable in longitudinal direction (R1).In a second direction (R2) in direction transverse to the first direction (R1), which are arranged between the lift element (20) and the rules of command (30) in the grooves (40) running on the line oblique in relation to the first direction (R1) and the second direction (R2).At least two sliding elements (50) that converts a movement of the rulers of command (30) along the first direction (R1) into a lifting movement of the lift element (20) in the second direction (R2).In order to ensure the drive especially maintenance free and continuously reliable all needles of the valve, it is envisaged that constructive components moveable relative to one another and, therefore, exposed to the risk of wear, especially the rules of command (30) And / or sliding elements (50).They are manufactured at least in part of a material self lubricant or a material Diamantino, or at least partially coated with a material self lubricant or glittering.
