Patent ID: 7997101

Claim:
An actuating and cooling assembly for a mold of a glassware molding machine, the mold comprising two half-molds, each of which has a number of through cooling conduits and defines an annular intermediate chamber communicating with respective inlets of said cooling conduits; the assembly comprising a supporting structure, and actuating means for moving the half-molds with respect to each other between a closed position and an open position; said actuating means comprising, for each said half-mold, a respective supporting and actuating arm connected to the relative half-mold and hinged to the fixed supporting structure to rotate about a fixed hinge axis; the assembly also comprising cooling means for feeding pressurized cooling air into said intermediate chambers; and the assembly being characterized in that each said supporting arm is hollow and defines an inner chamber having an outlet communicating with the relative said intermediate chamber, and an inlet formed through an outer lateral wall of said supporting arm and extending in a cooling air inflow direction parallel to said fixed hinge axes; wherein said outer lateral wall is bounded by an outer first flat surface perpendicular to said fixed hinge axes; the outer said first flat surface cooperating in fluidtight manner with a corresponding second flat surface connected to said supporting structure; wherein said first and second flat surface cooperate in sliding manner as the relative said supporting arm rotates about said fixed hinge axis.
