A device for molding core articles made of composite materials contains a housing, which bearing surface is conical, a sectional forming draw plate, which consists, at least, of three identical segments, which in whole form an external conical surface for installation in the bearing surface of housing and internal forming surface, which corresponds to form and size of the formed article, and parting planes of segments are made at an angle to the longitudinal axis of the draw plates, moreover additionally downstream of the forming surface it consecutively contains a calibration surface, which are separated between them by a ring groove, in which at least one radial opening is made, and the diameter of forming surface is smaller than the diameter of calibration surface. |
