<p>Provided is a molding die and a manufacturing method for the same capable of both shortening a molding cycle and improving transferability from a die to a resin. Inside a surface layer (13), a lower surface layer (14) and a thermal insulating layer (15) are formed, and therefore, there is no necessity to significantly vary the temperature of a molding die (10) at injection molding time of a resin, and furthermore, temperature distribution also approaches being uniform, and therefore, it is possible to correspondingly achieve shortening of the molding cycle time. Meanwhile, the temperatures of a convex portion (13a) and the vicinity thereof are also maintained at a high temperature, and therefore, it is possible to achieve improvement of transferability from the molding die (10) to the resin.</p> |
