Zusammenfassung:	Means are provided which permit rapidly extracting the needle assembly of a partible blow mold toward the mold axis through the bore of the mold section in which it is operable. These means include a stop member positioned in the bore for delimiting the advancing stroke of the needle assembly, such member being detachably fastened through the face of the mold section. Improved means for automatically admitting pressurized fluid to the hollow interior of the blow needle after penetration of the parison by the needle may also be provided.
