An apparatus comprises a conveying device and a plurality of blow molding stations arranged on the conveying device. Each blow molding station includes a blow mold. A clean room is provided inside which the plastics material pre-forms are conveyed. The blow mold has two lateral parts and a bottom part that jointly form a cavity inside which a plastics material pre-form is shaped into a plastics material container. A drive device moves the lateral parts or the bottom part of the blow mold. A coupling device couples the drive device to a lateral part. A mounting device mounts the coupling device.
