Abstract
A pin closure nozzle for injection molding molds has several working pistons acting on the same closure pin. These working pistons are arranged on a common throughgoing piston rod. Each piston rides in its own chamber and the piston rod passes through and is slidingly guided in openings in the chamber floors. The piston rod thus has at least two sliding guides and is accordingly prevented from tilting.
