DEVICE FOR DRIVING TWO MOLD HALVES OF A GLASS FORMING MACHINE

摘要

The invention relates to a glass forming machine (5) with brackets (2; 3) that are mounted to be pivoted about an axis (4). Every bracket (2; 3) is provided with form tool halves (6; 7). A first link (10) is articulated to a first articulation point (9) of every bracket (2; 3). A second link (12) is articulated to a second articulation point (11) of the first link ( 10), said second link, in turn, being articulated to a third articulation point (13) of the glass forming machine (5). A rod (14) is articulated to the second articulation point (11), said rod being articulated with its other end to a crank pin (15) of a crank (16). Each of the two cranks (16) is coaxially linked with a gear wheel (17; 18). The gear wheels (17; 18) are diametrically opposed and engage with an endless screw (21) that is driven by an electric servomotor (29) by means of a transmission (30) to rotate and reciprocate.
