Patent ID: 6848896

Claim:
Device for adjusting the “vertical” position of a blow mandrel of a blow mold machine on a blow mandrel carrier provided moveable up and down on a machine frame of the blow mold machine, upon which at least two blow mandrels are provided, which serve for the simultaneous blowing of mold hollow bodies which are blown in die cavities of a blow mold provided below the blow mandrel carrier, wherein the blow mandrel causes during penetration into the blow mold both a calibration of the neck area of the mold hollow body as well as a separation of plastic material protruding outward beyond the neck, wherein the separation occurs by pinching the protruding material by means of a ring shaped cutting edge of the respective blow mandrel, which when extending into the blow mold lies against a conical counter surface of the blow mold and by this lying against accomplishes a cutting of the excess projecting plastic material along a circle along the conical surface, wherein the blow mandrel is provided axially displaceable in a carrier fixed receptacle and is adjustable or as the case may be secured by means of a set or adjusting screw in the position for the pinching of the projecting excess material, thereby characterized, that an adjusting screw ( 29 ) is provided accessible and rotatable from the outside of the machine, and is guided screwable in a threaded bore ( 26 ) of the blow mandrel receptacle, of which its axis ( 27 ) intersects, preferably perpendicular, to the central axis ( 28 ) of the blow mandrel ( 10 ), and that a force-form-locking achieving translation device ( 29 , 32 , 34 ) is provided, which translates the axial adjustment stroke of the adjusting screw into an adjustment stroke of the blow mandrel, which occurs in the direction of the central longitudinal axis thereof.
