Mold

摘要

A mold includes a body, a first movable member and a second movable member. The body defines a first cavity. The first movable member defines a second cavity. The first movable member reciprocates along a predetermined movement axis with respect to the mold. The second movable member is movable along the movement axis with respect to the first movable member in the body for selectively connecting and disconnecting the second cavity and the first cavity according to the movement of the second movable member. A first material is supplied to one of the first cavity and the second cavity with the first and second cavities disconnected from each other. Then a second material is supplied to the other one of the first and second cavities with the first and second cavities connected to each other.
