Abstract
Un método para desprender una pieza de fuelle resiliente (22) de un molde de inyeccion, que comprende el paso de moldear por inyeccion una pieza de fuelle resiliente alrededor de un perno de corazon (28) colineal y una varilla desmoldeadora (38), rodeados por una cavidad dividida (30). La pieza de fuelle (22) tiene dos extremos abiertos (44, 50), uno (44) de los cuales es substancialmente rígido y está cerrado por la varilla desmoldeadora (38) que pasa a través del mismo. El segundo extremo abierto (50) es resiliente. Otro paso comprende abrir la cavidad dividida para permitir que la pieza de fuelle (22) sea desmoldeada del perno de corazon (28). Otro paso comprende expandir a la pieza de fuelle radialmente hacia afuera del perno de corazon. Simultáneamente con la expansion de la pieza de fuelle, un paso de empujar al extremo abierto substancialmente rígido (44) de la pieza de fuelle mediante la varilla desmoldeadora (38) provoca que la porcion resiliente (46) y el extremo abierto resiliente (50) sean desmoldeados del perno de corazon (28). Finalmente, el extremo abierto substancialmente rígido (44) de la pieza de fuelle es expulsado de la varilla desmoldeadora (38).
