摘要：
An electrohydraulic hybrid drive for a plastic injection molding machine having at least one hydraulic actuator, at least one feed system for feeding the hydraulic fluid for actuation of the hydraulic actuators, at least one electric motor for operating the feed system for the hydraulic actuators, at least one further electric motor for driving the extruder screw of a plasticator device, a joint frequency convertor which actuates both of the electrical motors and a switching device circuited between the frequency converter and at least one of the electrical motors.
