Abstract

An apparatus for moulding plastic preforms into plastic containers may include at least one blow mould and a plurality of closure elements cooperating with one another in order to transfer the blow mould between an open condition and a closed condition, in which the blow mould forms a cavity, within which the plastic preforms may be expanded into plastic containers. The closure elements include at least one first mould section and one second mould section. The first mould section and the second mould section may be moved between the closed position and the open position in relation to one another. In a closed condition, the first and second mould sections are locked together. The closure elements may further include a bottom section which may be moved relative to the first and second mould sections in order to close the cavity in one direction. According to various aspects, the bottom section initiates the closing of the mould sections and/or the locking of the mould sections in a closed condition of the blow mould.
