Claims

[Scope of Claim for Utility Model Registration] A toothed shaft having a plurality of toothed grooves fixed to either the movable platen or the fixed platen of an injection molding machine and arranged in series in the axial direction, and the movable platen or the fixed platen. A lock plate attached to either the other and movable between an engaged position and a non-engaged position with the tooth groove of the toothed shaft, and a lock plate provided on the safety door that moves the lock plate into the engaged position when the safety door is in the open position. A mechanical safety device for an injection molding machine having a cam capable of moving the lock plate to the disengaged position when the safety door is in the closed position and moving the lock plate to the disengaged position when the safety door is in the closed position. an actuator is provided, the actuator being coupled to the lock plate to move and constrain the lock plate to a non-engaged position when actuated and to disengage the lock plate when non-actuated. Mechanical safety device for injection molding machines.
