ツドを備えたことを特徴とする射出成形金型。 An injection mold for ejecting a molded product in two stages and releasing the mold, the mold having a first eject pin fixed thereto.
A second ejector pin is inserted into the second ejector plate so as to be able to move forward and backward within the range of at least the second stage ejection stroke length, and is always elastically biased to the backward limit position. The movable side mold plate is provided with a second stage ejecting means consisting of a lever mechanism pivotally supported so as to be able to swing to counteract the elastic biasing force, and the movable side mold plate is provided with a lever mechanism that abuts the other end of the lever mechanism during the second stage ejection process. An injection mold characterized by being equipped with an accessible press rod.
