Abstract
An injection mold includes a stationary platen carrying a pair of stationary die sections, a movable platen carrying a pair of movable die sections, and a pair of floating die sections disposed between the movable and stationary die sections. The respective floating and stationary die sections are mutually configured to define a pair of die cavities which are arranged for alternate communication with an injector unit. The floating die sections are selectively connectable to their associated movable and stationary die sections to expose one of the die cavities for article ejection, while maintaining the other die cavity closed for continuing a curing stage.
