摘要： A hydraulic control system comprises actuators, hydraulic lines for driving the actuators, and a control unit. According to an operation mode, the hydraulic lines are grouped by being separated or joined and composes multiple hydraulic line groups. The control unit selectively controls a master between the hydraulic lines contained in each hydraulic line group, and slave functions and performs control so that only one master is included within one hydraulic line group which is independent from an arbitrary operation mode. Each hydraulic line comprises at least one servo drive set consisting of a hydraulic pump, a servo motor, a servo driver and an encoder for pressure feed-back. The servo driver of each hydraulic line is formed to vary the master or slave functions. The servo driver operates according to the command of the control unit when being operated with the master and follows the master arranged in the identical group when being operated with the slave. Accordingly, one hydraulic line which is independent from the injection molding machine is controlled with one master. Collision between control loops is prevented, and action errors are prevented according to that. [Reference numerals] (150) Control unit;(AA,BB) Communication linkage
