Abstract:
In an injection cylinder which can be connected with a plunger, the internal portion of the cylinder part is partitioned by a piston into a rod-side chamber on the side of the piston rod and a head-side chamber on the opposite side. An accumulator can supply a hydraulic fluid to the head-side chamber. A head-use pressure sensor can detect a pressure of the head-side chamber. A flow control valve can control a flow rate of the hydraulic fluid discharged from the rod-side chamber. A control device includes an OP control part which starts open control driving the flow control valve to the opening direction after the start of supply of the hydraulic fluid from the accumulator to the head-side chamber conditional on the detection pressure of the head-use pressure sensor rising up to the predetermined set value.

Claim (Index 1):
An injection apparatus comprising\n an injection cylinder which includes\n a piston rod connectable to a plunger capable of sliding in a sleeve communicated with an interior of the die, \n a piston fixed to the piston rod, and \n a cylinder part slidably accommodating the piston, \n in which the internal portion of the cylinder part is partitioned by the piston into a rod-side chamber on the piston rod side and a head-side chamber on the opposite side; \n a liquid pressure source which can supply a hydraulic fluid to the head-side chamber; a head-use pressure sensor which can detect a pressure of the head-side chamber; a flow control valve which can control a flow rate of the hydraulic fluid discharged from the rod-side chamber; and a control device which includes an open control part starting open control driving the flow control valve to an opening direction after the start of supply of the hydraulic fluid from the liquid pressure source to the head-side chamber conditional on a detection pressure of the head-use pressure sensor rising up to a predetermined set value.
