PURPOSE:To perfectly retract a door member and a cover member from the leading end part of a cylinder assembly if necessary by respectively mounting the member and the cover member to the front surface of a front platen in a horizontally rotatable manner. CONSTITUTION:A door member 6 is present at a closure position during the injection process of an injection molding machine or during purging and, when it is necessary to revolve a cylinder assembly at the time of the replacement of said assembly, only the door member 6 is rotated to open the front. The inspection, cleaning or the like of an injection nozzle 5 are usually performed by revolving the cylinder assembly but, when these works are required during an injection molding process, not only the door member 6 but also a cover member 7 becoming the obstruction of said works are revolved around a hinge while a nozzle touch state is kept to set the door member to an open position and retracted from the leading end part 4 of the cylinder assembly. The opening/ closing only of the door member 6 can be simply performed because the cover member 7 is fixed at a fixing part 12 by a thumb screw 15. |
