ることを特徴とする樹脂の圧縮成形用金型構造。 A compression method in which a sheet-shaped resin molding material is placed on a lower mold, and this molding material is heat-pressed between the upper mold and the lower mold to form a resin molded product with a convex portion in the center. The mold structure is such that an opening covered by a resin molding material is formed at a position where a convex part of a resin molded product is formed in the lower mold, and a clearance is provided between the opening and the peripheral wall surface of the opening. A slide core is provided, which is housed so as to be movable up and down, and which forms a concave portion that comes into close contact with the peripheral wall surface to form a convex portion with the peripheral wall surface by descending when the convex portion is formed. and a suction means for suctioning gas in the opening through the clearance until the slide core reaches the lower end and forms the recess. Molding mold structure.
