PURPOSE:To reduce the cost and operation time of the above machine by providing fixedly a gate cut cylinder concentrically with a clamping ram between the movable platen of the injection molding machine and the clamping ram and providing an ejector cylinder recessed in the center of the clamping ram so as to extend to a predetermined depth. CONSTITUTION:A gate cat cylinder 10 is fixed to a clamping ram 4 by a plurality of mounting bolts 11 and also to a movable platen 3 by a plurality of mounting bolts 12. A piston rod 19A is fitted into an ejector cylinder 18 recessed in the clamping ram 4 so as to extend to a predetermined depth from the top end surface of said clamping ram 4, in such a state that the piston rod 19A protrudes into the inner space of a hollow-shaped gate cat piston 13. The piston rod 19A is formed so as to be capable of moving forward and backward between a gland 21 mounted fixedly to the clamping ram 4 by a plurality of mounting bolts 20 and the bottom surface of the ejector cylinder 18. |
