Mold including side walls with locking projections

摘要

A mold defining a mold cavity for manufacture of an article, the mold comprising a plurality of mold side wall members, each of the side wall members including opposite end portions and including an inwardly facing surface comprising a mold surface for forming at least a portion of a side wall of the molded article. The side wall members are moveable from a closed position wherein the side wall members cooperate with said first and second end wall members to define a mold cavity conforming to at least a portion of the desired exterior dimensions of the article, and an open position in which each of the side wall members is displaced laterally outwardly of its closed position and away from the end wall members to a location in spaced relation from the end wall members. First end portions of the side wall members include projections adapted to be housed in cavities in the first end wall member when the first end wall member and the side wall members are in the closed position and to prevent outward movement of the side wall members. Opposite end portions of the side wall members also each include projections adapted to be housed in cavitites in the second end wall member.
