NOVELTY - The method involves providing product cavity space (51) along with a clamping mold opening direction of a metal mold (1). The mold is an injection mold. The molded article is simultaneously molded using the metal mold. The metal mold is equipped with a spool (21), a runner (31), and a gate (41) which lead to the product cavity space. The runner is the orthogonal runner part extended from the spool in the direction orthogonal to the clamping mold opening direction of the metal mold.    USE - Method for molding liquid elastomer used for gasket for fuel cells, or packing of general others.    ADVANTAGE - The amount of discard of molding material is reduced and the produce-ability is improved. The mold release of flash is made easy or opening and closing of split type is made easy.    DETAILED DESCRIPTION - The present invention is to provide the molding method of the liquid elastomer in which it can cut down the discarded amount of the molding material and the mold does not become large in size on plane at the same time, when molding multiple molded products using moreover, the mold and the fabrication efficiency is therefore good. To accomplish the above objects, it is the method for molding the molded product consisting of the liquid elastomer by using the mold and the mold (1) is the injection mold and multiple product cavity spaces (51) are side by side formed into the type tightening and type open direction of the corresponding mold and at the same time, multiple molded products are molded using the mold. The sprue (21) put through to the mold to multiple product cavity spaces, and the runner (31) and gate (41) are included and the orthogonal runner area (32), and the parallel runner area (33) extended and installed from the orthogonal runner area in a direction parallel to the type tightening and type open direction of the corresponding mold are included and the parallel runner area is arranged in the outer peripheral side of the multiple product cavity spaces. As to the orthogonal runner area (32), the runner is extended and installed from the sprue to the direction orthogonal to the type tightening of the corresponding mold and type open direction.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the clamping state of the metal mold.    Metal mold (1)    Spool (21)    Runner (31)    Gate (41)    Product cavity space (51)
