The device is used for blow molding containers of a thermoplastic material and has at least one blow station with at least one blow mold. The blow mold is comprised of at least two blow mold segments held by supports. At least one of the blow mold segments is arranged such that it can slide relative to its support. The support is equipped with at least two guide elements for the movable blow mold segment. The guide element has a hard core that is connected to the blow mold segment. In addition, the core is embedded, at least in part, in an elastomer that is carried by the support. A circumferential seal made of an elastomer is provided in order to make available an area of pressure action in order to support pneumatic positioning of the blow mold segment; this seal has a seal lip that makes area contact with the support when pressure is applied.
A device for blow moulding containers of a thermoplastic material that has at least one blow station with at least one blow mould that is comprised of at least two blow mould segments held by supports and wherein at least one of the blow mould segments is arranged such that it can move relative to its support, characterized in that the support (48, 49) is equipped with at least two guide elements (5) for the movable blow mould segment and in that the guide element (5) has a hard core (8) that is connected to the blow mould segment and that is embedded, at least in part, in an elastomer (9) that is carried by the support (48, 49).
A device for blow moulding containers of a thermoplastic material that has at least one blow station with at least one blow mould hat is comprised of at least two blow mould segments held by supports and wherein at least one of the blow mould segments is arranged such that it can move relative to its support, characterized in that the blow mould segment is sealed by a circumferential elastomer seal (14) with respect to the support (48, 49) in an area of action provided for the application of pneumatic pressure, and in that the seal (14) has a seal lip (26) that makes area contact with the support (48, 49) when pressure is applied.
