Claims

[Claims for Utility Model Registration] (1) A fixed mold is attached to a fixed frame, a movable mold is attached to a movable frame, and when the mold is closed, multiple cavities are formed by the inner surface of the side wall of the fixed mold and the outer surface of the side wall of the movable mold. In the mold for in-mold bead foaming formed by forming a mold, the fixed mold and the movable mold are formed so that the distance between the side wall portions gradually becomes smaller toward the front, and the side wall portion of the fixed mold is rotatable. A mold for in-mold bead foam molding, characterized by having a movable wall section. (2) The movable wall portion has a through hole formed in an actuating plate provided upright in the movable wall portion, and an inner inclined overhang portion and an outer inclined overhang portion are formed in the actuated rod that is moved by an air cylinder for the actuated rod. , wherein the inner inclined overhang or the outer inclined overhang rotates inward or outward by coming into contact with the inner or outer surface of the through hole. Mold for in-mold bead foaming.
