The actuator is divided into an upper actuator portion and a lower actuator portion. The sector is also divided into an upper sector portion and a lower sector portion. The mold further has a connection for connecting the actuator portions together to raise the lower actuator portion by a predetermined amount with the rise of the upper actuator portion and for separating the lower actuator portion from the upper actuator portion upon the portion rising more than the predetermined amount, when the mold is opened.
