Abstract: A blow molding machine for producing three-dimensional low-waste articles including at least one horizontally separated blow mold formed of upper and lower half-molds, a device for vertically displacing at least one of the upper and lower half-molds between an open mold position in which the upper half-mold is spaced from the lower half-mold, and a closed mold position in which the upper and lower half-molds engage each other, a device for locking the upper and lower half-molds in the closed position, and a device for pivoting the upper half-mold in the open mold position about a horizontal axis by substantially 90° and/or displacing the upper half mold in a horizontal plane.
