Abstract
A blow mold (1) for a stretching machine or a glass blowing machine, comprising two mold halves (3, 4) which are pivotably connected by at least one connecting pin (2), and a shutting device and locking device in the form of a closing clamp (7) which can be slid directly onto the mold halves (3, 4) from the side of the connecting pin (2). The mold halves (3, 4) are closed around the connecting pin (2) by the sliding, pressing contact of the closing clamp (7) and in the closed position, are pressed against each other without a gap, resulting in a mechanically simple, space-saving blow mold (1).

Blow mold (1) for a stretching blow machine or a glass blowing machine, comprising two mold halves (3, 4) which can be pivoted to each other about at least one connection axis (2) for forming at least one mold cavity (5) defined by inner walls of the mold halves, a closing device for pivoting the mold halves to each other into a closed position, a closing clamp (7) having a substantially U-shaped inner surface (8) adapted to be driven by a pushing device (9, 14) for pressing the mold halves against each other without gaps into the closed position, both mold halves (3, 4) being directly connected with each other at one side by the connection axis (2), the closing clamp (7) being arranged at the side of the mold halves facing the connection axis (2) and pushable as a closing device directly on outer surfaces of the mold halves (3, 4) from the side of the connection axis (2), the pushed closing clamp (7) defining in its pushed condition a device for holding the closed mold halves in their closed position.
Method for adjusting two mold halves (3, 4) of a blow mold which are to be pivoted about at least one connection axis (2), in a stretching blow machine or a glass blowing machine, comprising pivoting the mold halves to each other by means of a closing device into a closed position in which both mold halves define at least one mold cavity (5, 5′), pressing both mold halves against each other in the closed position by means of a closing clamp (7), when shifted into an engagement position, first pivoting both mold halves (3, 4) into the closed position by sliding and pressing contact of the closing clamp (7), which is directly shifted from the side of the connection axis (2) over the outer surfaces of the mold halves (3, 4), and pressing both mold halves (3, 4) against each other without gaps.
