Abstract

PERFECTIONNEMENT A UN APPAREIL DESTINE A MOULER A CHAUD UN ARTICLE ET A REVETIR L'UNE DE SES SURFACES, COMPORTANT DEUX COQUILLES QUI, REUNIES, DEFINISSENT UNE EMPREINTE DE MOULAGE. A L'UNE DES COQUILLES, 2, EST INCORPORE UN DISPOSITIF D'INJECTION COMPORTANT UN POINTEAU QUI PEUT S'ENGAGER DANS LA PAROI DE LA COQUILLE. EN RECULANT, LE POINTEAU DEGAGE L'ORIFICE DE L'AJUTAGE D'INJECTION, CE QUI PERMET AU DISPOSITIF D'INJECTION DE REFOULER DANS L'EMPREINTE DE LA MATIERE DESTINEE A REVETIR UNE SURFACE DE L'ARTICLE PENDANT QUE LES COQUILLES SONT REUNIES. L'AJUTAGE EST ENTOURE PAR UNE JAQUETTE DE REFROIDISSEMENT. APPLICATIONS AU MOULAGE DES MATIERES PLASTIQUES.
