Abstract: The invention relates to an interlock for a column, comprising a piston with a piston rod, such that the piston rod is disposed in a claw bush, the claw bush being disposed in a single- or multi-part plate, such that the piston and the claw bush can move in the single- or multi-part plate. In one embodiment, the claw bush has at least two stages, to apply the force in a distributed manner, the contour of the stages corresponding to the end of the piston rod and/or to the end of the column, the average radius of the first stage differing from the average radius of the second stage.

Abstract: An injection-molding die, which comprises a movable die platen guided via crossbeams is provided, wherein an adjusting element is positively connected to each crossbeam and can be adjusted axially relative to the crossbeam via a central drive and the position of the die platen changes relative to the crossbeams. An apparatus and method is provided in which at least one of the adjusting elements can be locked against an axial movement and against rotation by means of a fixing device. The fixing device may be a piston element in a closure cover arranged on the movable die platen.
