PURPOSE:To mold a grip of high quality by a method wherein the title mold is constituted of a split molding mold, consisting of a top force and a bottom force, and a cylindrical body consisting of rubber or elastomer while a cavity mold, arranged in the cavity of the split mold and specifying the profile of the grip to be molded, as well as a core pin, forming a penetrating hole along the axial direction of the grip, are included. CONSTITUTION:A cavity mold 40 and a core pin 50 are set in a split molding mold 30 and non-foamable urethane resin is poured and filled into the cavity C of the cavity mold 40 through the resin pouring port 36 of the split molding mold 30 and the resin supplying port 42 of the cavity mold 40 with a compara tively low pressure. The core pin 50 is retreated in a state wherein the urethane resin, filled into the cavity mold 40, is cured and a grip 60 is molded, then, the bottom force 32 and the top force 34 of the sllit mold are split and moved to effect mold opening. Thereafter, the cavity mold 40 and the molded grip 60 are taken out of the split mold 30. The resin supplying port 42 of the cavity mold 40 is expanded to pull the formed grip in the mold out thereby releasing it from the mold. |
