Abstract
The invention concerns a molding unit for an extrusion-blow molding machine comprising a mold in two parts, each mold-half (12, 14) being borne by a moveable support (16, 18), and of the type in which the molding unit (10) comprises, between at least one of the mold-halves (12) and the associated support (16), compensating means (30) which push the mold-half transversely toward the other mold-half, characterized in that the mechanism (24) for moving the supports is linked to at least said associated support (32), by means of elastically deformable means that are suitable for compensating for the deformation of the support (15[sic], 32), created by the forces exerted by the compensating means (30).
