The method for the lubrication of glass forming molds (3a,3b) with at least a nozzle (2) spraying a lubricating media in the molds comprises at least the following steps: displacement of a nozzle from a resting position to a working position into said mold (3a, 3b); movement of said nozzle in said mold while spraying with said nozzle a lubricating media to lubricate the inner surface of said mold; ) application of vacuum at least during the spraying step to evacuate emissions; ) once the mold has been lubricated, displacement of the nozzle in a resting position allowing the loading of a gob in said mold; ) circulation the lubrication media in the nozzle before and after the lubrication step to avoid stagnant lubrication media remaining in the nozzle and/or ensure constant mixing of solid particles in said media.

A closing mechanism for the mold halves of an I.S. machine, including two yoke-like mold holders mounted on parallel guides and movable between a closed position and an open position by means of a drive. A spindle transmission is provided laterally to at least one guide, the spindle transmission including a threaded spindle that is connected to the drive via a transmission and is in engagement with two threaded sleeves, each of which is connected to one of the two mold holders via two threaded sections running in opposite directions. By means of the drive, a servomotor, the opening and closing movement of the mold holders is carried out. Two pneumatically actuated piston-cylinder units are provided in order to apply the clamping force required between the mold holders or the mold halves in the closed position.

A method for producing a hollow glass product by an I.S. machine, said method being a press-blow or blow-blow method and implementing at least one parison mould and one blow mould, said method comprising the lubrication of said parison mould, the lubrication comprising spraying via a nozzle, said nozzle being carried by the arm of a mobile robot movable along the parison mould side of the I.S. machine, characterised in that said mobile robot is configured to bring said nozzle into the lubricating position after the glass gob has left the parison mould for the blow mould; spray the lubricant into said parison mould; withdraw said nozzle from the lubricating position before the transfer arm returns between the two half-moulds of the parison mould
