<P>PROBLEM TO BE SOLVED: To provide an injection device for molding machine, capable of suitably performing injection by a cylinder device and another drive unit. <P>SOLUTION: A control device 15 drives, in low-speed injection, a plunger 5 only by the driving force of the drive unit 11 with an output member 71 being in contact with a joint 27 fixed to a piston rod 25 in a forward direction, and drives, in high-speed injection, the plunger 5 only by the driving force of the cylinder device 7 with the connection by an attachment/detachment portion 13 being released, and also moves the piston rod 25 forward relatively to a driven portion. When the plunger is retreated, the control device retreats the plunger 5 by the driving force of the drive unit 11 with the connection by the attachment/detachment portion 13 being attained. <P>COPYRIGHT: (C)2013,JPO&INPIT |
