MOLD STOPPER There is provided an improved stopper assembly to terminate the flow of molten metal into a mold cavity and to prevent reverse flow of molten metal after the mold has been filled. The stopper assembly includes a mounting spider secured within an opening of the mold cope and a stopper is frictionally held by the mounting spider and aligned so that a stopper washer is adapted to seat against the ingate of the mold. |
