Abstract
Device for producing hollow bodies from thermoplastic plastic material in a blow molding process, comprising a cavity mold having at least two mold parts (2, 2a), wherein the mold parts (2, 2a) are movable relative to each other, a support device (6) on which at least one mold part (2) is displaceably mounted, and a first drive device (7) for displacing the at least one mold part on the support device (6) so that the two mold parts (2, 2a) approach or move apart in a displacement direction (18), wherein a second drive device (7) is configured to apply a closing force acting essentially in the displacement direction (18).
Claims22
Device for producing hollow bodies from thermoplastic plastic material in a blow molding process, comprising:
- a cavity mold having at least two mold parts, wherein the mold parts are movable relative to each other;
- a support device on which at least one mold part is displaceably mounted;
- and
- a first drive device configured to displace the at least one mold part on the support device so that the two mold parts approach each other or move apart in a displacement direction;
- and,
- a second drive device is configured to apply a closing force acting essentially in the displacement direction, wherein a toggle lever having a first and a second lever element, which are connected via a joint, is configured to displace the at least one mold part, and the second drive device is more powerful than the first drive device.
