Abstract
A mold for manufacturing an annular object of elastic material such as a sealing ring having a reinforcing element which is completely or partially embedded therein, comprising support surfaces on pin members supported by the mold and projecting into the mold cavity which support and retain the reinforcing element in the correct position within the mold during injection of the elastic material to be formed within the mold cavity. The pin and the mold cavity have opposing surfaces which guide the inserted reinforcing element into the correct position prior to injection of the elastic material. The mold is made in separate parts so that the parts can be removed after the elastic material has set, to open the cavity for removal of the finished product with the reinforcing element embedded therein.
