Abstract

An apparatus for molding plastic preforms into plastic containers may include at least one blow molding station having a cavity. Within the cavity, the plastic preforms may be expanded into plastic containers. The blowing station has a bottom portion which delimits the cavity. The bottom portion is detachably disposed on a carrier by a fastening mechanism. The fastening mechanism has at least one pin-like body disposed on a first fastening element. The pin-like body engages in a condition in which the bottom portion is fastened to the carrier in a groove which is provided in a second fastening element. The pin-like body is displaceable relative to the carrier in the groove for fastening the bottom portion, and the groove is designed in such a way that an end section of the pin-like body may pass through the groove in a first section of the groove and cannot pass through the groove in a second section of the groove.
