PURPOSE:To omit the operation of cutting a runner and the operation of correcting the mark left by cutting the runner, by restraining an auxiliary runner, moving the auxiliary runner differently from the movement of the molded item thereby cutting the auxiliary runner from the molded item, and then releasing the molded item from the mold. CONSTITUTION:When releasing, first a push 7 is driven to cause molded item ejecting pins 6 to project from a core plate 1, and then a little later an auxiliary runner push plate 8 is driven to cause an auxiliary runner ejecting pin 9 to project from the core plate 1. Accordingly, when the molded item 11 is pushed out by the molded item ejecting pins 6, since the auxiliary runner 12 is restrained in such a way that an undercut connecting section 12a thereof is held by a hook section 16, first the connecting section 12a is cut to release the molded item, and then when the auxiliary runner ejecting pin 9 is projected, the auxiliary runner 12 is cut away from a submarine gate 13 and is pushed out from the core plate to be released. |
