Abstract
Collapsible core devices, related methods and injection molding tools for use in injection molding processes, the core device configured to collapse upon rotation of a centrally disposed rotating shaft. In some aspects the core device includes a rotatable shaft, moveable outer wall components positioned radially from the shaft, a first disk operatively engaged with the shaft and having at least a first slot configured to receive a first pin connected to a moveable outer wall component, and a second disk secured in a fixed position and having at least a second slot configured to receive the first pin, such that rotation of the rotatable shaft causes the pin to slide within the second slot toward the shaft and causing the outer wall component to move toward the shaft.
