Abstract

Molde para piezas inyectadas con contrasalidas internas que comprende una parte macho de molde formada por dos piezas complementarias, las cuales se acoplan correspondientemente una dentro de la otra, con posibilidad de desplazamiento axial y giro entre ellas, determinando la pieza componente exterior unas ranuras, en las cuales se alojan unas formas paralelas que la pieza componente interior posee en la periferia, de modo que mediante un desplazamiento axial y un giro entre ambas piezas componentes, las formas paralelas salen de las ranuras y se desvían del enfrentamiento respecto de las mismas permitiendo la extracción de la pieza inyectada sin forzarla.
