Abstract

An unloader-separator attached to a die casting machine which includes a swing arm having grippers to hold the gate having components thereon. The swing arm holding the gate is rotated to a second position. A punch platen pushes the components through openings in the window platen which corresponds with the components on the gate. The swing arm releases the gate remnants for recycling, rotates to the first position and the cycle repeats. A link arm connects the swing arm to a cam unit which controls the rotation of the swing arm to a cam unit which controls the rotation of the swing arm. The cam unit also provides overload protection.
