Abstract

PURPOSE: To make an injection molding machine simple and certain by using a screw rod in engaging and disengaging a pressure resistant rod rixed to a movable platen and a rotary perforated disc locking the movable platen and a ram.
CONSTITUTION: A metal mold is attached to a fixed platen 2 and a movable platen respectively and, when a solenoid of a change-over valve 16 is magnetcally excited, the movable platen 7 advanced to close the metal mold. In this time, it is confirmed that a leading end of a pressure resistant rod 8 is comletely protruded or not from a pore of a perforated disc 14 and, when the leading end of the rod 8 is not protruded, a solenoid of a change-over valve 17 is magnetically excited to communicate a cylinder chamber 9a of an oil pressure cylinder 9 fixed to a ram collar part 4A with a tank and a screw rod 11 threaded in a collar part 3a of a mold clamping cylinder 3 is rotated to retract to a lefthand direction. Next, when th solenoid of a change-over valve 17 is magnetically deenergized, the ram 4 is moved to a lefthand direction and the collar part 4a of the ram 4 is contacted with a leading end of the screw rod 11 to stop the same.
