Abstract

A device for blow molding plastic containers includes an openable and closable blow mold for the conversion of tempered plastic preforms, whereby an inner blow pressure is applied to the plastic containers. The blow mold contains at least two shell like blow mold pieces that are arranged interchangeably at a blow mold carrier and that each contains cooling fluid pipes as conducts for a cooling fluid extending therein to temper the blow mold during and/or after blow molding of the plastic containers. The cooling fluid pipes in the blow mold are connected to a central cooling fluid supply. A coupling module that is associated with the blow mold carrier is arranged between the central cooling fluid supply and the cooling fluid pipes extending in the blow mold pieces. The coupling module and the blow mold carrier are associated spatially and/or structurally.
