Abstract
Each neck tool half is mounted on a neck tool holder and together they are movable from the illustrated initial position in a parison mold station to a finishing mold station. On each neck tool holder is secured a movable part of a distribution device for cooling air. A stationary part of the distribution device transfers cooling air from a stationary supply device having a valve. Between the stationary and movable parts there is a jointing gap which is inclined to the vertical. The cooling air is blown through nozzle apertures against the outside of the neck tool half.
Claims24
An apparatus for use in molding glass, comprising:
- a neck ring for forming a mouth of a glass container, said neck ring comprising a longitudinally divided neck tool having neck tool halves, wherein each said neck tool half has a respective neck tool holder for moving said neck tool half between a closed and an open position;
- a parison mold station for forming a parison, said parison being held and transportable by said neck ring from an initial position at said parison mold station to a finishing mold station;
- a stationary supply device having an outlet for supplying a cooling fluid;
- a distribution device having an inlet which cooperates with said outlet of said stationary supply device to receive said cooling fluid therefrom and at least one final outlet, said distribution device being associated with at least one said neck tool half and its respective neck tool holder to direct said cooling fluid through the at least one final outlet into contact with the associated neck tool half;
- and
- said distribution device being divided into a stationary part arranged in said parison mold station and a movable part which moves with the associated neck tool holder, said movable part having a movable part inlet which is positioned and arranged opposite and in cooperation with a stationary part outlet in said stationery part when said neck ring is in its initial position.
An apparatus for cooling a neck ring forming the mouth of a glass container in a glass molding machine, comprising:
- said neck ring comprising a longitudinally divided neck tool, said divided neck tool comprising neck tool halves, wherein each said neck tool half has a respective neck tool holder for moving the neck tool halves between a closed position and an open position;
- a parison mold station for forming a parison, said parison being held and transportable by the neck ring between said parison mold station and a finishing mold station, and wherein the neck ring is returnable from said finishing station to an initial position at said parison mold station;
- a stationary supply device associated with each neck tool holder for supplying cooling fluid, each stationary supply device having an outlet for the cooling fluid;
- a distribution device associated with each said neck tool half and respective neck tool holder, each said distribution device having an inlet positioned and arranged in cooperation with said stationary supply device outlet associated therewith for receiving the cooling fluid therefrom;
- wherein each said distribution device has at least one final outlet through which the cooling fluid is directed into contact with said associated neck tool half;
- and
- wherein each said distribution device is divided into a stationary part arranged in said parison mold station and a part movable with said associated neck tool holder, said movable part having an inlet which is positioned and arranged opposite and in cooperation with an outlet in said stationary part when the neck ring is in said initial position.
