INJECTION APPARATUS

摘要

An injection apparatus includes a pressure accumulating portion connected to an operation chamber of an injection cylinder. A control unit controls the speed at which the injection cylinder moves and is connected to a rod of the injection cylinder. The control unit includes a rotary shaft that follows the movement of the rod and is capable of moving in the same direction as the rod, a conversion mechanism that converts the linear motion of the rod into the rotation of the rotary shaft, and a rotation member coupled to the rotary shaft. The control unit further includes a resistance generating member that generates a frictional resistance by coming into sliding contact with the rotation member, an actuating member that is moved by an electric drive source, and a movement mechanism that follows the movement of the actuating member and moves the resistance generating member relative to the rotation member.
