A device for compression moulding of plastic objects, comprising a plurality of compression-moulding units (9), each of which comprises a core mould element and a moulding cavity (2) filled by dropping into it a dose of plastic material; each moulding unit (9) is designed to carry out a moulding sequence comprising an operation of opening of the mould, an operation of filling of the moulding cavity, and an operation of closing of the mould. The device further comprises cam mechanisms for taking the moulding cavity outside of the vertical axes of the positive-mould element between the operation of opening of the mould and the operation of filling of the moulding cavity. The invention further relates to a method for the production of plastic objects by means of compression moulding device as described above.
L'invention concerne un dispositif de moulage par compression d'objets en plastique comprenant une pluralité d'unités de moulage par compression (9), chacune présentant un élément de moule à noyau et une cavité de moulage (2) remplie par dépôt d'une dose de matériau plastique; chaque unité de moulage (9) est conçue pour effectuer une séquence de moulage consistant à ouvrir le moule, à remplir la cavité de moulage et à fermer le moule. Le dispositif comprend également des mécanismes à cam permettant de retirer la cavité de moulage des axes verticaux de l'élément de moule positif entre l'ouverture du moule et le remplissage de la cavité de moulage. L'invention concerne également un procédé de production d'objets en plastique au moyen du dispositif de moulage par compression susmentionné.
