Abstract
A mold opening and closing mechanism for an I.S. machine having a plurality of individual sections each having a section frame having a top wall. A pair of mold support mechanisms are supported above the top wall of the section frame for linear displacement and displaced by a motor having, a rotary output, secured to the top wall, via a rotary to linear transmission supported above the top wall of the section frame horizontally adjacent the mold support mechanisms.
Claims6
A mold opening and closing mechanism for an I.S. machine having a plurality of identical section frames each having a top wall and each having a station for forming glass, the station including a mold opening and closing mechanism for supporting an opposed pair of mold halves, said mold opening and closing mechanism comprising
- a mold carrier supported above the top wall of the section frame for horizontal displacement along a predetermined path between a retracted position and an advanced position,
- a motor having a rotary output,
- a transmission mechanism, including a lead screw, interconnecting said rotary output and said mold carrier for displacing said mold carrier along said predetermined path between the advanced and retracted positions, as the motor operates, by converting the rotary output of said motor into the horizontal displacement of said mold carrier, and
- a housing on top of the top wall of said section frame housing said transmission mechanism.
