  • Publication number: 20220396041
    Abstract: A mold for producing a metal-resin composite by press-forming a metal member and integrally molding the metal member that is press-formed and a resin material includes an upper mold and a lower mold that sandwich the metal member and the resin material. The upper mold includes a first press surface for press-forming the metal member and a second press surface for integrally molding the metal member and the resin material. A distance between the first press surface and the lower mold is shorter than a distance between the second press surface and the lower mold.

  • Publication number: 20220395883
    Abstract: The apparatus includes an upper mold and a lower mold that sandwich the metal member and the resin material, and a drive unit that vertically moves an elastic member attached to a molding surface of the upper mold and at least one of the upper mold and the lower mold. A cavity for arranging the resin material is provided by the upper mold 110 and the lower mold. The elastic member is arranged so as to seal the resin material in the cavity.

  • Publication number: 20220395885
    Abstract: 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.

  • Publication number: 20220297221
    Abstract: A joining method for overlapping and joining a plate-shaped portion of a first metal member and a plate-shaped portion of a second metal member, where the first metal member and the second metal member are made of dissimilar materials, includes a first step of forming an insertion hole in each of the plate-shaped portion of the first metal member and the plate-shaped portion of the second metal member, where the insertion holes communicate with each other when the plate-shaped portions of the first metal member and the second metal member are overlapped with each other, a second step of disposing a first joining member made of a metal material on a side of the plate-shaped portion of the first metal member opposite to the second metal member, a third step of inserting a second joining member made of the same metal material as that of the first joining member into the first metal member from a side of the second metal member through the insertion holes while the plate-shaped portions of the first metal member

  • Publication number: 20220281528
    Abstract: A structural member is elongated in a longitudinal direction, and includes a first member made of a steel plate and a second member made of a steel plate, the first member and the second member being joined. In the structural member, a closed cross-sectional shape is formed by the first member and the second member in a cross section perpendicular to the longitudinal direction. The first member has a tensile strength of equal to or greater than 980 MPa, and includes a first hemming process part subjected to hemming bending at both end parts in a width direction orthogonal to the longitudinal direction. The second member has a tensile strength of equal to or greater than 980 MPa, and includes a second bonded part held in the first hemming process part at both end parts in the width direction and bonded to the first hemming process part by an adhesive.
