Abstract

PURPOSE: To facilitate the insertion of film at the integral molding of the film and, in addition, allow the film to go easily along with molds by a structure wherein an inclined cam surface is provided at the head of a cam member and a cam bearing part, against which the inclined cam surface of the member abuts, is provided on a slide core.
CONSTITUTION: When molds are closed by shifting a core 2 and the movable side of a cavity 5, the tapered part 11 of a cam member 9 which protrudes from a parting face 22 is inserted against the restoring force of a compression spring 14 into a through hole 7 by being pushed with the member of the parting face 23 on the cavity 5 side. At this time, the tapered part 11 of the cam member 9 abuts against the tapered part 8 of a slide core 1 so a to push the slide core 1 toward its closing direction, resulting in shifting the slide core 1 to its closing position against the restoring force of a compression spring 6. In the state that the core 2 and the cavity 5 are closed completely, the tapered part 11 of the cam member 9 merges in the tapered part 8 of a through hole 7 and the end of the tapered part 11 lies flush with the parting face 22 of the slide core 1 and closely contacts with the member of the parting face 23 of the cavity 5 side. Because the slide core 1 is also in its closed state under the above-mentioned state, the condition that the molding of a molded product is possible is reestablished.
