Abstract
An improved injection molding apparatus for forming articles including an aperture therethrough, the apparatus including a first mold half having a first bore; a second mold half having a second bore substantially aligned with the first bore, in which the first mold half and the second mold half form a mold cavity space in the mold closed position, the mold cavity space having a thickness T1 adjacent the first bore, the improvement comprising a slidable mold injection nozzle located inside the first bore having a molding position and a post molding position, the nozzle including an inlet in fluid communication with a molten material supply means; an outlet including a nozzle tip, the nozzle tip having a gating portion and being in communication with the mold cavity space when the nozzle is in the molding position; and an unobstructed nozzle melt channel between the inlet and the outlet to guide the flowing molten material from the supply means towards the mold cavity space in tubular flow up to the outlet; independently movable sliding valve gating means located in the second bore and having a molding position therein and a post molding sealing position in the first bore, the valve gating means including mold core means to form a hole in the article to be molded, means for converting the flow of molten material from tubular to radial in the mold closed position, and nozzle channel sealing means to prevent leakage of molten material in the mold opened position; a circular mold gate of an adaptable thickness T2, the mold gate being formed in the mold closed position between the gating portion of the nozzle tip and the valve gating means, the mold gate having no mechanical obstructions, whereby the maximum thickness T2 of the gate is substantially equal to the thickness T1 of the mold cavity space; first motive means to slide the mold injection nozzle inside the first bore between the molding and the post molding positions; and second motive means to slide the valve gating means at least partially from the molding position inside the second bore to the post molding sealing position inside the first bore.
