    摘要: An injection molding system (20) is provided including an extruder unit (22) having an injection actuator (38) for injecting a melt into a mold assembly (40); and a clamping unit (24), the clamping unit (24) configured to retain the mold assembly (40) during injection. A power pack (46) is provided, including a fixed-target accumulator assembly (62) operable to discharge hydraulic fluid at a fixed hydraulic pressure to the clamping unit (24) and a first pump being connected with the clamping unit (24), the first pump operable for charging the fixed-target accumulator assembly (62) to the fixed hydraulic pressure. The power pack (46) also includes a variable-target accumulator assembly (66) operable to discharge hydraulic fluid at a variable hydraulic pressure to the injection actuator (38) during the molding cycle; and a second pump connected to the variable-target accumulator assembly (66), the second pump operable for charging the variable-target accumulator assembly (66) to the variable hydraulic pressure.
