Abstract

PROBLEM TO BE SOLVED: To shorten a molding cycle by opening a runner stripper plate and a fixed mold before a fixed mold and a movable mold of a mold are fully opened so that a molding can be taken out, to complete the taking-out of a runner. SOLUTION: A mold 10 is closed, a resin is filled and molded. A moving side mounting plate 11B is moved. A runner stripper plate 12 and a fixed mold 14 are opened by a compression spring 22. A runner 2 is separated from a molding 1 while the runner 2 remains fixed to the plate 1. The plate 12 and the plate 11A are opened by an air cylinder 23 contained in the plate 11a, and the runner 2 is removable by removing a runner locking pin 33 fixed with the runner 2. When a detector 30B detects that an opening amount of the mold 114 from the plate 12 can remove the runner 2 by the movement of the plate 11B, a runner removing unit 32 enters the mold 10 to take out the runner 2 out of the mold 10, and draw and drop the molding 1 from a movable mold 12 by a stripper plate 6. Thus, a molding cycle can be shortened.
