The invention concerns an injection-moulding machine comprising a substantially C-shaped machine frame (1) on whose one leg (9) a stationary die platen (2) is mounted and on whose other leg (7) a closure mechanism (4) is mounted for driving a movable die platen (8). The free ends of the machine frame legs, which ends are not connected by spars, deform under the influence of the closure force occurring during the closure process. Disposed between the stationary die platen (2) and/or the closure mechanism (4), on the one hand, and the machine frame (1), on the other, is at least one retaining pan (5, 6) which deforms when the closure force is applied, whereby the stationary die platen (2) or the closure mechanism (4) is tilted relative to the machine frame (1).
L'invention concerne une presse d'injection présentant un bâti (1) pratiquement en forme de C. Un plateau porte-outillage fixe (2) est monté sur un montant (9) du bâti (1) et un mécanisme de fermeture (4) destiné à entraîner un plateau porte-outillage mobile (8) est monté sur l'autre montant (7). Les extrémités libres des montants du bâti, non raccordées par des traverses, se déforment sous l'effet de la force de fermeture apparaissant pendant le processus de fermeture. Au moins un élément de maintien (5, 6) est disposé entre le plateau porte-outillage fixe (2) et/ou le mécanisme de fermeture (4) d'une part et le bâti (1) d'autre part. Cet élément de maintien (5, 6) est déformé lors de l'application de la force de fermeture (2), le plateau porte-outillage fixe (2) ou le mécanisme de fermeture (4) étant basculé par rapport au bâti (1).
