Moulding machine for the production of pressure or push moulded parts, of the type comprising a stationary plate (1) and a moving plate (2) and two half- moulds forming a mould once they are closed. According to the invention, the machine comprises, associated with one of the plates (2), a support (22) carrying two identical half-moulds (5, 6), which can be transversely shifted in front of the plate (2) in a reciprocating movement so as to alternately position each half-mould (5, 6) either in an injection position or in an ejection position. The machine also comprises spraying manifolds (48, 53, 54) carried by the support (22) and associated with the other plate (1), the manifolds being arranged so as be located briefly opposite the half-moulds (5, 6) after the moulding has been ejected or removed.
L'invention concerne une machine à mouler pour la réalisation de pièces moulées sous pression ou par poussée d'un matériau, du type comportant deux plateaux fixe (1) et mobile (2) et des demi-moules aptes à constituer un moule après fermeture. Selon l'invention, cette machine comporte, associée à un des plateaux (2), une table-support (22) portant deux demi-moules (5, 6) identiques, apte à se déplacer transversalement devant le plateau (2) selon un mouvement alternatif de façon à positionner chaque demi-moule (5, 6) alternativement soit dans une position d'injection, soit dans une position éjection. De plus, cette machine comporte des rampes de pulvérisation (48, 53, 54) respectivement portées par la table-support (22) et associées à l'autre plateau (1), agencées pour se trouver momentanément en regard des demi-moules (5, 6) en vis-à-vis après éjection du moulage ou extraction de la pièce moulée.
