An apparatus for the shaping of plastics-material containers with a blow mold, wherein the blow mold has at least one first and one second blow-mold part, may include at least one first and one second carrier element for holding the blow-mold parts. The carrier elements are movable relative to one another at least in one plane, in order to be transferred at least from a closed configuration into an opened configuration. In this case the carrier elements each have a receiving area for receiving one blow-mold part in each case, wherein the blow-mold parts in the closed configuration form at least one cavity for the expansion of the containers. The blow-mold parts may be capable of being coupled in a magnetic and releasable manner to each other and/or at least one of the blow-mold parts is capable of being coupled in a magnetic and releasable manner to at least one carrier element.
