Apparatus, mold set, and method for producing metal-resin composite

An apparatus for producing a metal-resin composite by press molding a metal member and a resin material, the apparatus comprising:

• a mold including an upper mold and a lower mold that sandwich the metal member and the resin material;
• a molding auxiliary component detachably fixed to the upper mold so as to fill at least a part of a cavity for arranging the resin material formed by the upper mold and the lower mold;
• and
• a drive unit that moves at least one of the upper mold and the lower mold in a vertical direction, wherein
• the molding auxiliary component has a first press surface for molding the metal member to form a molded metal member,
• the upper mold has a second press surface for directly contacting the resin material for integrally molding the resin material to the molded metal member,
• a distance between the first press surface and the lower mold in a state where the molding auxiliary component is attached is shorter than a distance between the second press surface and the lower mold in a state where the molding auxiliary component is removed, and
• the upper and lower molds are for pressing the resin material between the second press surface and the lower mold to cause the resin material to flow to fill the cavity with the resin material when the molding auxiliary component is removed such that the molding auxiliary component and the resin material have substantially the same shape.
