Solidworks collapsible core animation

[plasticsstudent]

Hi, I am trying to create an animation in solidworks of a collapsible core for an injection mold. The problem I am having is I cannot get the core to collapse or expand when another part collides with (they simply merge). Any help on how to make this work would be greatly appreciated.

Thank you for your time
