Apparatus for cooling a blank mold in a glass receptacle forming machine with multiple dampers

An apparatus for cooling a blank mold in a glass receptacle forming machine including a blank mold for forming a glass receptacle, a plurality of passages for providing cooling air in a circumferential wall of the blank mold and extending vertically through the circumferential wall, the apparatus comprising:

• a plenum chamber provided adjacent to said passages for temporarily storing cooling air to be supplied to said passages, said plenum chamber having at least one inner partition wall therein to define a plurality of cavities;
• and
• a damper device fixed to said plenum chamber for integrally supporting a plurality of dampers, each of said plurality of dampers being respectively provided for adjusting the amount of cooling air supplied to each said cavity, wherein an opening degree of each of said plurality of dampers is variably controllable so that the amount of cooling air to be supplied to said passages through said cavities is adjustable, wherein said damper device is provided at a site whereat a plurality of said inner partition walls converge.
