Title
(EN) AN EXTRUDING DIE FOR A NON-INFLATABLE MULTI-HOLE HOLLOW TYRE
(FR) FILIERE D'EXTRUSION POUR UN PNEU CREUX MULTI-TROUS NON GONFLABLE
(ZH) 免充气多孔空心轮胎挤压模具
Abstract
(EN) An extruding die for a non-inflatable multi-hole hollow tyre comprises a die core (2) and a die frame (1) connected between the feeding means for an extruder and the die core (2) . A feeding through hole (3) is provided in the die frame (1) , which is connected between the feeding inlet for the feeding means and the outlet (4) for the die core (2). The outlet (4) is provided with several die blocks (5) whose shape match that of the hollow cavities of the tyre. The blocks (5) directly or indirectly connect with the wall of the outlet by means of some connecting pieces (6) composed of thin walls.
(FR) L'invention concerne une filière d'extrusion pour un pneu creux multi-trous non gonflable qui comporte un noyau de filière (2) et un support de filière (1) relié entre les moyens d'alimentation pour une extrudeuse et le noyau de filière (2). Selon l'invention, le support de filière (1) possède un trou de passage d'alimentation (3), et est relié entre l'orifice d'entrée d'alimentation pour le moyen d'alimentation et l'orifice de sortie (4) pour le noyau de filière (2). L'orifice de sortie (4) comporte plusieurs blocs à filières (5) dont la forme correspond à celle des cavités creuses du pneu. Les blocs (5) sont reliés directement ou indirectement à la paroi de l'orifice de sortie au moyen de certaines pièces de liaison (6) comportant des parois minces.
