Abstract
En vue de s'affranchir de toute contrainte en ce qui concerne l'épaisseur des nervures de renfort des pièces tout en obtenant un aspect de surface parfait pour celles-ci, on capte (en 7) la vitesse de déplacement de l'organe mobile (4) de la presse et lorsqu'on détecte le point 0 de cette vitesse, on réduit la pression exercée sur ledit organe afin de laisser à ce dernier la possibilité de se soulever sous l'effet de la pression interne développée par la polymérisation de la matière. Application du système aux presses de moulage par compression équipées d'un piston de transfert.In order to overcome any constraint with regard to the thickness of the reinforcing ribs of the parts while obtaining a perfect surface appearance for them, the speed of movement of the movable member is captured (at 7) (4) of the press and when point 0 of this speed is detected, the pressure exerted on said member is reduced in order to give the latter the possibility of lifting under the effect of the internal pressure developed by the polymerization of matter. Application of the system to compression molding presses equipped with a transfer piston.
