A method for forming an as-cast hole by using a core involves forming an undercut and casting by using a core die which is slidable at an angle with respect to mold closing and opening directions. At the same time, an as-cast hole with an axial direction different from the slide direction of the core die is formed. To form the as-cast hole, a floating core is slidably disposed in the core die for movement in the axial direction of the as-cast hole. An apparatus for practicing the method includes a stationary die, a movable die and the core die containing the slidable floating core.
