Title (EN) CAROUSEL-TYPE MACHINE FOR MAKING INJECTION MOLDED PIECES COMPRISING TWO MATERIALS AND RELATED PRODUCTION METHOD
(FR) MACHINE DE TYPE CARROUSEL DESTINÉE À LA FABRICATION DE PIÈCES MOULÉES PAR INJECTION COMPRENANT DEUX MATÉRIAUX ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract:
(EN) A method is described for making injection molded pieces comprising two different materials for producing soles (10) for footwear with tread and midsole, wherein the first and second material are injected in a same mold (6) comprising a first imprint (6a) and a second imprint (6b) which, by being inserted in succession in a matrix (6c), locate recesses wherein tread and midsole are injected, the production being performed on machines of a carousel type (2), the carousel (2) comprising three stations (2a, 2b, 2c); the production of the soles (10) is performed in three revolutions of the carousel (2) according to the following modes: at the first revolution, the tread is extracted in the first station (2a); at the second revolution, the midsole is injected in the first station (2a); at the third revolution, the complete sole (10) is injected in the third station (2c) and the tread of the following sole (10) is injected; in order to produce a complete sole (10) every two revolutions of the carousel (2).
(FR) L'invention concerne un procédé de fabrication de pièces moulées par injection comprenant deux matériaux différents pour produire des semelles (10) pour des chaussures à lamelle et semelle intercalaire, le premier et le deuxième matériau étant injectés dans un même moule (6) comprenant une première empreinte (6a) et une deuxième empreinte (6b) qui, en étant insérés successivement dans une matrice (6c), positionnent des évidements dans lesquels sont injectés la lamelle et la semelle intercalaire, la production étant effectuée sur des machines de type carrousel (2), le carrousel (2) comprenant trois stations (2a, 2b, 2c) ; la production des semelles (10) est réalisée en trois tours du carrousel (2) selon les modes suivants : au premier tour, la lamelle est extraite dans la première station (2a) ; au deuxième tour, la semelle intercalaire est injectée dans la première station (2a) ; au troisième tour, la semelle complète (10) est injectée dans la troisième station (2c) et la lamelle de la semelle suivante (10) est injectée ; afin de produire une semelle complète (10) tous les deux tours du carrousel (2).
