发明名称 METHOD AND DEVICE FOR CONTROLLING A LINEAR MOTION AXIS
摘要 The invention relates to a method and device for controlling a linear motion axis, particularly of the injection screw (43) or a melt piston for an injection molding machine. Said device comprises a hydraulically driven piston (45) having a piston chamber (A) and a rod chamber (B). According to the solution proposed by the invention, at least one process phase is controlled/regulated by means of two parallel proportional valves, an injection valve (1) and a metering valve (2). The two proportional valves can be connected in parallel or in combination. The control/regulation of the driven piston (45) preferably uses digital technology. An enormous reduction in energy consumption and smooth transitions between the process phases are achieved with a hydraulic linear drive.
