Abstract: An improved golf ball injection process and mold uses electrically driven part ejection mechanisms as actuators to control retractable core pins that support a preformed core in a spherical mold cavity. The electrically driven, actuator controlled pins can be precisely and independently controlled in both the upper and lower mold segments to achieve the desired positioning and velocities in the vertical axis, with varying degrees of pinch to hold the spherical core inserts. The forward and retract position of the core pins, as well as the ability to profile pin velocities, can be easily adjusted by the molding machine's computer process controller without changing mechanical stops internal to the mold. The sequence timing can be set so that the core insert can be suspended and encapsulated by plastic with varying timing, allowing for the core insert to be shifted during the molding process.
