Abstract
A mold comprises a base, a split die and a plunger. The base has longitudinal shoulders with resilient elements, and sloping surfaces which form an upwardly flaring nest adapted to accommodate a vertically movable die. The side walls of the die have their sloping surfaces in contact with the sloping surfaces of the longitudinal shoulders and, together with the die end walls, are placed around the die bottom. Provided between the base and the die are means for lifting the latter and means for supporting the die bottom in the raised position after the die has been lowered. Such die construction makes it possible to reduce the time required for its assembly and disassembly, as well as for detaching the finished abrasive segment from the die walls.
