Abstract
A fixing device for moulds for plastic articles, where a pair of half-moulds (3, 4) in which a force plug (11) can be inserted, comprises at least one tie rod (6) for keeping the two half-moulds in a closed position, the said tie rod being hinged, at one end, to the mobile half-mould and having a second end of a hammer-headed shape which hooks to two gripping jaws (60, 61). The tie rod (6) is hinged to a connecting rod which rotates on a pivot fixed to the resting base (14), which, in the movement of rotation, sets the tie rod (6) along the line corresponding to the centroid of the pressure forces produced during the moulding operation.
