Title (EN) PISTON FOR COLD-CHAMBER INJECTION MACHINES
(FR) PISTON POUR MACHINE D'INJECTION À CHAMBRE FROIDE
(ES) PISTÓN PARA MÁQUINAS DE INYECCIÓN DE CÁMARA FRÍA
Abstract:
(EN) The invention comprises a support (2) and an external body (3) with a sealing ring (5), joined by a bayonet lock ring (6) independent of the external body (3) and divided into two parts (6a) fitted onto a groove (21) in the support (2) and connected by long screws (7) inserted into threaded holes (61). The piston preferably includes a spring bush (4) as a part that adjusts to the container, independent of the external body (3) and of the bayonet lock ring (6), and, under the bush, a conical spring ring (8) which exerts pressure on the two parts that form the bush (4), tending to expand same. The piston also includes alternating transverse grooves (81) along the edges thereof for receiving conical metal tips (9) inserted through holes (63) in the bayonet lock ring (6).
(FR) Le piston selon l'invention comprend un support (2) et un corps externe (3) doté d'une bague de raccord (5), reliés par une bague à fermeture à baïonnette (6), indépendante du corps externe (3) et divisée en deux parties (6a) venant s'ajuster sur une rainure (21) du support (2) et reliées par des vis longues (7) introduites dans des trous taraudés (61). Le piston comprend de préférence, comme pièce d'ajustement au conteneur, un manchon souple (4) indépendant du corps externe (3) et de la bague à fermeture à baïonnette (6), sous lequel est disposée une bague ressort (8) conique qui exerce une pression sur les deux parties formant le manchon (4), tendant à élargir ce dernier. La bague ressort présente en outre des rainures transversales (81) alternées sur ses bords, aptes à recevoir des pointes (9) coniques métalliques enfoncées à travers des trous (63) de la bague à fermeture à baïonnette (6).
(ES) Comprende un soporte (2) y un cuerpo externo (3) con un anillo de junta (5) unidos por un anillo de cierre de bayoneta (6), independiente del cuerpo exterior (3) y dividido en dos partes (6a) ajustadas sobre una ranura (21) del soporte (2) y unidas por unos tornillos largos (7) insertados en unos orificios roscados (61). Preferentemente incorpora un casquillo (4) elástico como pieza de ajuste al contenedor, independiente del cuerpo externo (3) y del anillo de cierre de bayoneta (6), bajo el cual incorpora un anillo de resorte (8) cónico que ejerce presión sobre las dos partes que forman el casquillo (4) tendiendo a expandirlo. Además presenta unas ranuras transversales (81) alternadas en sus bordes aptas para recibir unas puntas (9) cónicas metálicas clavadas a través de unos taladros (63) del anillo de cierre de bayoneta (6).
