Vorrichtung zum Auswerfen von Spritzgussteilen

摘要

The invention relates to a device for ejecting injection moulded parts from an injection mould held by a platen (19) in an injection moulding machine. Said device comprises an ejection plate (9) to which at least one ejector pin is fixed or can be fixed, said pin being positioned in a moveable tool half of the injection mould in an axially displaceable manner. The ejector receiving element can be moved from a retraction position into an ejection position via linear guiding mechanisms (15), parallel to the longitudinal axis of the at least one ejector pin, by means of a motor-driven crank mechanism comprising a crankshaft (1), a crank (2) and a connecting rod (3). A spring force storage device is provided, the spring force thereof acting in the direction of the ejection position, and the connecting rod (3) is embodied as an arched component.
