る。Therefore, as described in, for example, JP-A-60-219020, when the product shape is a quadrangle, the cavity of the mold can be projected and retracted from the four sides inside the cavity on the four sides of the end face opened in the center. A slide core is provided, and a drive device that slides the slide core is provided. Then, a cut-and-formed skin body is set in the cavity, and each drive mechanism is operated to move each slide core from four directions. By sliding it toward the inside of the cavity, and winding the end of the skin into the inside of the cavity with the tip of this slide core, the end of the end is inserted when the synthetic resin is introduced into the cavity to form the core material. There has been proposed a molding die that is wound around the back surface of the material and integrated.

A pair of mold bodies facing each other and separated from each other, and a synthetic resin is introduced into the cavity formed by the pair of mold bodies together with a synthetic resin. A molding die for integrally laminating and molding a core material, which comprises: The turn-in plate projects inward from the opening edge of the cavity when the end face of one mold body is rotated, winds the end portion of the skin body inside the cavity, and moves away from the end face of one mold body in the separating direction. Is provided with a winding edge portion that can be retracted to the outside of the opening edge portion of the cavity, and a biasing force is applied to the winding plate in a direction of separating the winding plate from the end surface of one mold body. Characterized by providing an elastic body to give A molding die with a skin terminal winding device.
