Abstract: An air ejector of a resin molding device includes air passages, air outlets through which air is injected, movable valves biased by bias members to close the air outlets, accommodation spaces in which the movable valves are movably contained, an air supply path through which air is supplied from an air supply source, and a pressure sensor to detect air pressure. After completing the mold removal, the air is supplied via the air supply path to the air passages at an air pressure smaller than the bias force of the bias members, and the air pressure is detected by the pressure sensor.

Abstract: A structure of a multilayer component in which a rigid core material, a soft surface material, and a cushioned foam layer provided between the core material and the surface material are integrated, wherein the core material includes an exposed core material portion without having the surface material and the form layer, the exposed core material portion is obtained by cutting off at least the surface material to be eliminated, and a cutting assist portion that projects toward the surface material or toward an opposite side of the surface material to assist cutting off with a cutting tool is provided in a part of the core material on which the surface material is cut off.

Abstract: The present invention relates to a method and a device for molding a soft and thin resin molded product, in which molten resin is injected into a molding space between a concave mold and a convex mold to mold the soft and thin resin molded product. The convex mold or the concave mold is opened while the soft and thin resin molded product is left in the concave mold in such a way as to become open in its concave-shaped portion. Then, at least two chuck tabs formed outside the concave-shaped portion of the soft and thin resin molded product left in the concave mold are each held by a chuck of a molded product removing machine, and the concave-shaped portion of the soft and thin resin molded product is supported by a support arm of the molded product removing machine.

Abstract: Provided are a resin molding device and a resin molding method for easily removing a thin and soft resin molded product from a mold with a good finish by sensing an operation failure of an air ejector reliably. An air ejector (22) of a resin molding device (20) comprises air passages (24a, 24b), air outlets (26a, 26b) through which air is injected, movable valves (27a, 27b) biased by bias members (29a, 29b) to close the air outlets (26a, 26b), accommodation spaces (28a, 28b) in which the movable valves (27a, 27b) are movably contained, an air supply path (32) through which air is supplied from an air supply source (33), and a pressure sensor (35) to detect air pressure. After completing the mold removal, the air is supplied via the air supply path to the air passages at an air pressure smaller than the bias force of the bias members, and the air pressure is detected by the pressure sensor.
