Abstract
A molding method of a liquid elastomer can reduce an amount of disposal of a molding material, and can prevent a metal mold from being enlarged in size on a plane when a plurality of molded articles are simultaneously molded by using the metal mold, thereby achieving a good manufacturing efficiency. The molding method of the liquid elastomer molds a molded article constructed by a liquid elastomer by using a metal mold, the metal mold is a metal mold for an injection molding, a plurality of product cavity spaces are provided side by side in a mold clamping and mold opening direction of the metal mold, and a plurality of molded articles are simultaneously molded by using the metal mold. The metal mold has a sprue, runners and gates which are communicated with a plurality of product cavity spaces. The runners have orthogonal runner portions and parallel runner portions.
