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.
An apparatus for moulding plastic preforms into plastic containers comprising at least one blow moulding station having a cavity, within which the plastic preforms may be expanded into plastic containers, the blow moulding station including a bottom portion which delimits the cavity, the bottom portion being detachably disposed on a carrier by a fastening mechanism, the fastening mechanism having at least one pin-like body disposed on a first fastening element, said pin-like body engaging in a groove provided in a second fastening element when in a condition in which the bottom portion is fastened to the carrier, the pin-like body being displaceable relative to the carrier in the groove for fastening the bottom portion and with the groove being designed in such a way that an end section of the pin-like body is permitted to pass through the groove in a first region of the groove and not permitted to pass through the groove in a second region of the groove.
A mounting assembly for mounting a bottom portion for an apparatus for moulding plastic preforms into plastic containers on a carrier, wherein the bottom portion is detachably mounted on a carrier by means of a fastening mechanism, wherein the fastening mechanism has at least one pin-like body provided on a first fastening element, which pin-like body engages in a condition in which the bottom portion is fastened to the carrier in a groove provided in a second fastening element, wherein the pin-like body is displaceable in the groove for fastening the bottom portion relative to the carrier 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 region of the groove and cannot pass through the groove in a second region of the groove.
