Abstract:
1. Blow mold for manufacturing containers from preforms, comprising a stationary mold half, at least one other mold half movable relative to the stationary mold half between closed and open positions, a bottom mold comprising a bottom mold axis (X) essentially perpendicular to the moving direction of the other mold half moveable relative to the mold halves between an engaged position and a removal position, and which can be at least positively locked with the mold halves against movements in the moving direction of the bottom mold in the engaged position and the closed position of the other mold half by at least one engaging collar element projecting outwards from the outer periphery of the bottom mold and being at least approximately parallel to the moving direction of the other mold half, and a counter engagement ring groove structure in the mold halves, wherein the engaging collar element at the bottom mold and at least the counter engagement ring groove structure form a bayonet catch in the stationary mold half which can be actuated in the movement of the bottom mold between the engaged position and the removal position by relative rotary motions of the engaging collar element about the bottom mold axis (X) and only essentially linear relative movements in the direction of the bottom mold axis (X) with respect at least to the stationary mold half.
