摘要： A mold is for press molding a metal plate and a resin material to produce a metal-resin composite. The mold includes an upper mold and a lower mold that sandwich the metal plate and the resin material. A cavity for arranging the resin material is provided by the upper mold and the lower mold. The upper mold has a recess into which the resin material leaking from the cavity is caused to flow.

摘要： The joined body includes a joint portion including a linear welding portion in which a first metal member and a second metal member are joined. The joint portion includes a main linear portion being linear and extending along a first direction being a direction corresponding to a load assumed to act on a component obtained by machining the joined body. The main linear portion is a portion whose angle formed with the first direction is 0 degrees or more and 15 degrees or less in the joint portion. The joint portion includes a plurality of the main linear portions arranged at intervals in a second direction being a direction intersecting with the first direction.

摘要： A method for manufacturing a press molded product includes forming a plurality of corner portions in a pressed portion of a pressed member, providing the pressed member between a first die and a second die, and press molding the pressed portion to decrease a height of the pressed portion. The press molding includes forming a pair of first bent portions in the pressed portion by means of the corner portions, the pair of first bent portions being bent to protrude toward the second die, forming a second bent portion in the pressed portion by means of the corner portions while holding the pair of first bent portions by a pair of holding portions, the second bent portion being bent to protrude toward the first die from a position between the pair of first bent portions, and pressing and deforming the second bent portion.

摘要： In a method for joining members of the present invention, a B-pillar, a rocker, a side panel served as frame members of a vehicle body, and an elastic body are provided. The B-pillar includes a tubular portion and an extension portion extended from the tubular portion. The rocker includes a first hole portion. The side panel includes a support portion. Next, the tubular portion of the B-pillar is inserted into the first hole portion of the rocker. The elastic body is inserted into the tubular portion of the rocker. The elastic body is pressurized in an axial line L1 direction of the tubular portion of the B-pillar to be expanded outward in a radial direction of the axial line L1, so that the tubular portion of the B-pillar is expanded and deformed to be joined to the first hole portion of the rocker by press-fitting. Further, the extension portion of the B-pillar and the support portion of the side panel are joined by a method different from joining by press-fitting.

摘要： A method for manufacturing a metal-resin composite includes preparing a mold including a first mold forming a housing portion and a second mold movable with respect to the first mold, housing an extruded material in the housing portion, arranging resin material on the first mold, moving the second mold to form a cavity defined by the extruded material and the mold, and filling the cavity with the resin material. In the filling, a protrusion of the extruded material is brought into close contact with the housing portion or its peripheral edge by molding pressure applied from the mold to the extruded material, and the cavity is disconnected from a gap between an inner surface of the housing portion and the extruded material.
