<p>There is described a press (1) having: a first and a second half-mold (6, 4) settable in a first position, in which they cooperate to define an injection cavity (2), and in a second position, in which they are detached; and a lever mechanism (14a, 14b, 14c, 14d) having a first lever (21a, 21b, 21c, 21d, 22a, 22b, 22c, 22d) connected to a fixed portion (5), and a second lever (20a, 20b, 20c, 20d) connected to the first half-mold (6) and to the first lever (21a, 21b, 21c, 21d, 22a, 22b, 22c, 22d); the second lever (20a, 20b, 20c, 20d) is parallel to a given direction (A) when the first half-mold (6) is in the first position; the second lever (20a, 20b, 20c, 20d) is inclined with respect to the direction (A) when the first half-mold (6) is in the second position; the press (1) has an actuator (41, 42; 40, 43) having a first member (46, 51) connected to the fixed portion (5), and a second member (47, 52) connected to the first half mold (6) and detached from the lever mechanism (14a, 14b, 14c, 14d); the first member (46, 51) and the second member (47, 52) slide in the direction (A); and the actuator (41, 42; 40, 43) is activated to move the first half-mold (6) into the first position and the second position.</p> |
