The invention concerns a moulding unit for an extrusion-blow moulding machine comprising a two-part mould, each mould-half (12, 14) being borne by a mobile support (16, 18), and wherein the moulding unit (10) includes, between at least on the mould-halves (12) and its associated support (16), compensating means (30) thrusting the half mould transversely towards the other mould-half. The invention is characterised in that the mechanism (24) moving the supports is linked at least with said associated support (32) via elastically deformable means capable of compensating the deformation of the support (15, 32) produced by the forces applied by the compensating means (30).
L'invention propose une unité de moulage pour une machine d'extrusion-soufflage comportant un moule en deux parties, chaque demi-moule (12, 14) étant porté par un support mobile (16, 18), et du type dans lequel l'unité de moulage (10) comporte, entre au moins l'un des demi-moules (12) et le support associé (16), des moyens de compensation (30) qui poussent transversalement le demi-moule en direction de l'autre demi-moule, caractérisée en ce que le mécanisme (24) de déplacements des supports est lié au moins au dit support associé (32) par l'intermédiaire de moyens déformables élastiquement aptes à compenser la déformation du support (15, 32) créée par les efforts exercés par les moyens de compensation (30).
