Abstract: A door locking device, in particular an electromagnetic door locking device, for a door with a rotary catch for a closing bolt of the door, wherein in particular said rotary catch can be acted upon or is acted upon in particular by a torque, wherein the rotary catch has a closing bearing surface. The door locking device includes a pivoting body, in particular a pivoting locking body, and a lever body, wherein the pivoting body is connected to the lever body by a connecting body, wherein the connecting body is connected by a first joint to the pivoting body and by a second joint to the lever body, wherein in a closed position of the rotary catch the closing bearing surface of the rotary catch is in contact or is able to be brought into contact with the first joint between the pivoting body and the connecting body.

Abstract: An actuation magnet is provided for moving a closure needle of a hot-runner nozzle of an injection molding tool. The actuation magnet has an armature which is coupled in movement to the closure needle and may be displaced between first and second cores by subjecting at least one coil to current. A permanent magnet is arranged in a manner such that it exerts an additional magnetic force on the armature in at least one, preferably two, movement directions.
