Abstract
Provided is a mold part for resin molding and a manufacturing method. A mold part for molding resin includes a base material layer, a design section and uneven sections which abut an inner surface so as to form ventilation sections. The design section has a design surface transferred by a reverse master having an uneven surface. At least the design section out of the base material layer and the design section is formed of a heat resistant material, and the mold part for resin molding is interchangeably attached to the molding tool so that a molding pressure acts in a direction to press the uneven sections against the inner surface of the molding tool at the time of molding the resin molded article.
Claims9
A manufacturing method for a mold part for resin molding which is to be interchangeably attached to a molding tool and mold a resin molded article formed with a design on a product surface side, comprising:
- a step of forming a base material layer;
- a step of forming a design section on a surface which is on one principal surface side of the base material layer and becomes the product surface side;
- and
- a step of forming uneven sections, which form ventilation sections between the uneven sections and an inner surface of the molding tool, on a surface located on the other principal surface side of the base material layer and to be held in contact with the inner surface of the molding tool;
- wherein at least the design section out of the base material layer and the design section is formed of a heat resistant material.
