Abstract
"DISPOSITIVO DE POSICIONAMENTO DE NúCLEO DE MOLDE". Um dispositivo de posicionamento de núcleo de molde (10) inclui um elemento de came (12) conduzido por um primeiro segmento de molde (16) que é configurado para engatar um seguidor de came conduzido por um segundo segmento de molde cooperante (30). O seguidor de came é fornecido em um cursor de núcleo (40) no qual um elemento de núcleo se estendendo externamente, tal como um pino de núcleo (48), é conectado. O cursor de núcleo é móvel na direção e para longe de uma cavidade de molde (36) para mover o pino de núcleo para dentro e para fora de uma posição dentro da cavidade de molde. O elemento de came inclui uma superfície de came de extensão (18) e uma superfície de came de retirada (22). A superfície de came de retirada inclui uma superfície de came de desprendimento (26) que faz a retração lenta do pino de núcleo com relação a parte moldada, e uma superfície de came de retração (78) que causa retirada mais rápida do cursor de núcleo e pino de núcleo depois que o pino de núcleo foi inicialmente separado da parte moldada."MOLD CORE POSITIONING DEVICE". A mold core positioning device (10) includes a cam element (12) driven by a first mold segment (16) which is configured to engage a cam follower driven by a second cooperating mold segment (30). The cam follower is provided on a core cursor (40) to which an externally extending core element, such as a core pin (48), is connected. The core slider is movable towards and away from a mold cavity (36) to move the core pin in and out of a position within the mold cavity. The cam element includes an extension cam surface (18) and a withdrawal cam surface (22). The withdraw cam surface includes a detach cam surface (26) which makes the core pin slowly retract with respect to the molded part, and a retraction cam surface (78) which causes faster withdrawal of the core cursor and core pin after the core pin was initially separated from the molded part.
