ABSTRACT:
An apparatus for injection molding an article includes a pair of mold members, at least one of which is movable toward and away from the other. Each mold member includes a base plate, a manifold plate and a cover plate. Each base plate has inner and outer surfaces with a mold cavity in its inner surface and an annular recess in its outer surface. A plurality of connected grooves is in the bottom of the recess to form a channel. The manifold plate is an annular plate which is seated in the recess in its respective base plate. The manifold plate has inlet and outlet passages which extend to separate ones of the grooves in the base plate. The cover plate extends across the outer surface of the base plate and the manifold plate to hold the manifold plate in the recess. One of the base plates has a hole therethrough from its outer surface to its mold cavity to allow the flow of molding material into the mold cavity.
