Abstract
To provide a film holding apparatus for an injection mold which is capable of surely holding a protective film on a specific position of a mold surface of the injection mold. The film holding apparatus for holding an inner film on the mold surface of the injection molds consisting of two coupled molds having substantially-vertical coupled surfaces thereof includes two positioning pins that can hang an upper edge side of the inner film on an upper edge portion of the mold surface of the mold, and upper and lower vacuum opening portions for film adsorption disposed so as to interpose the positioning pins therebetween from the upper and lower sides. The upper vacuum opening portion is formed in a line, which extends along an upper edge of the mold surface.
