A device for manufacturing hollow glass article consists of a plurality of modular stations that, among other things, comprise blank molds and finish molds, wherein a housing (6) is provided and can be displaced along a blank mold side (3) in order to carry out at least control and servicing functions, and wherein said housing is formed by a key-like structure that is open in the direction of the blank mold side (3) and serves as a carrier for at least one manipulation element (7) consisting of multiple sections. On its free end, this manipulation element carries a tool or a device that is ready for use after it has reached the respective station. The shielding effect of the housing (6) reliably protects an operator side against accidents due to inadvertent interventions in machine motion sequences.

A blow head mounting arrangement for use to facilitate installation and removal of a blow head from a blow head mounting member. The blow head has a first engagement member for removable engagement with a second engagement member to removably attach the blow head to the blow head mounting member. Once engaged, the blow head is retained on the blow head mounting member by rotating the blow head into a locked position in which it is retained until it is rotated in the opposite direction by a locking mechanism.

The present invention relates to an apparatus for blow-molding a glass bottle, and more particularly, to an apparatus for blow-molding a glass bottle in which molding air is injected into a pair of mold bodies such that molten glass accommodated in the mold bodies is formed into a glass bottle and a groove is formed at the center of the inner side of the bottom surface of the glass bottle. The apparatus for blow-molding a glass bottle of the present invention uses a blow mold (10) configured to include: a pair of mold bodies (11) forming a tubular body; a base mold (12) which molds the bottom surface of the glass bottle; and a blowing head (13) which are arranged in the upper portions of the mold bodies (11) and into which molding air is injected such that the glass bottle is expanded after primary molding and closely contacts the inner walls of the mold bodies (11) and the base mold (12). A groove molder (20) is provided on the inner circumferential edge portion of the blowing head (13) such that a groove portion (15) can be molded on the inner side of the bottom surface of the glass bottle (14).

A process for manufacturing a hollow glass product using an I.S. machine and a robot that can move alongside blank molds of the I.S. machine, wherein the robot is capable of replacing one or more blank molds, section after section. The I.S. machine for manufacturing hollow glass products includes a robot that can move alongside the blank molds, and the robot is capable of carrying plural tools having different functions, simultaneously and/or alternately, chosen from an electromagnet, and/or a spray tube for greasing by spraying, and/or an optical pyrometer, an infrared or equivalent viewing port, and/or a rotary abrasive tool, and/or a camera or equivalent.
