Date Jul. 26, 1990.The frame of a mould comprises at least one rigid transverse structure element disposed in a zone which is substantially distant from the ends of the frame. The transverse element comprises two end parts between which are disposed support beams of the lateral moulding walls. Jacks each fixed on an end bearing part of the structure element are connected via their movable rod to the beam in zones which are distant from the longitudinal ends of the beam. The jacks make it possible to achieve both the displacement of the walls between their opening and closing positions and the clamping of the mould. Restriction of the clamping stresses is provided by the structure element. The bending moment of the beams remains low since the points of application of the stresses on the beams are distant from the ends of these beams and chosen as a function of the clamping conditions of the mould.
