More Information
Summary:The blowing mold (10) comprises two half molds (1, 2) with a cyclic opening and closing device, a drum cam (11) with two cam tracks (13, 14), a cam follower (12) and levers (29) for transmitting the opening and closing motion of the two half molds (1, 2). The cam follower(12) follows the first cam track (13) to produce a first opening movement of the two half molds with a first maximum opening angle greater than that achieved when the cam follower (12) follows the second cam track (14) of the drum cam (11). A disc cam (15) with one (17) or two cam tracks (18) controls the vertical translation of the mold bottom (8) for the opening and closing movement.
