ABSTRACT:
Cooperating guide means are provided on a vibratory mold and a cover plate reciprocable into and out of the open top of the mold. The guide means are arranged to guide the cover plate during its vertical stroke just before it enters into the mold and to prevent any but vertical movements between the mold and the cover plate when the cover plate is within the mold. The operative length of the guide means is less than the length of the vertical stroke.
