Claims

[Scope of utility model registration request]

A mechanical safety device for an injection molding machine consists of a sawtooth rod whose rear end is fixed to a movable platen and whose tip is inserted through a hole in the fixed platen, and a sawtooth rod which is fixed to the inner surface of the fixed platen. It consists of a guide through which the rod is inserted, a flat plate part that is guided by the guide and can be locked to the sawtooth rod, and a forked part, and the roller is supported by a pin inserted and fixed in the forked part. The plate is fixed to the lower surface of the upper frame of the safety door that covers at least one side between the movable platen and the fixed platen, and as the safety door moves, it enters the lower surface of the roller and raises the flexible plate; A mechanical safety device for an injection molding machine, characterized by comprising a cam that releases the locking of a shield plate to a sawtooth rod.
