Abstract:
1. A device for opening/closing a mold of a glassware forming machine, said mold having a longitudinal plane of symmetry, and comprising two movable half-molds, said device comprising: a supporting structure; for each of two said half-molds, a respective mold-holder, and a respective supporting and actuating arm hinged to said respective mold-holder to rotate about a respective movable hinge axis and to a supporting structure to rotate about a respective fixed hinge axis; and an actuating means for rotating said supporting and actuating arms in opposite directions with respect to said supporting structure and for moving said half-molds between a closed position and an open position; wherein said fixed hinge axes are located on opposite sides of said plane of symmetry, and at such a distance from said plane of symmetry that, when said half-molds are in said closed position, a line intersecting said respective fixed hinge axis and said respective movable hinge axis of each respective supporting and actuating arm extends substantially parallel to said plane of symmetry; wherein each of two said half-molds surround a corresponding movable retaining means for retaining semifinished articles formed in said respective mold, said corresponding movable retaining means being maintained connected to said respective half-molds and in a plane substantially perpendicular to said plane of symmetry, further comprising, for each said mold-holder, a respective single adjusting lever for adjusting an angular position of said corresponding mold-holder about said respective movable hinge axis and with respect to said respective supporting and actuating arm, each said adjusting lever having opposite ends hinged to said relative mold-holder and to said supporting structure.
