Abstract: Disclosed is a method of processing the surface of a cavity a casting die wherein the fluidity is good even if the shape of the surface of the cavity (castings) has a complex shape, mold releasability are excellent, reprocessing is possible, and the life of the die can be prolonged. A step (A) for forming hemispherical first dimples (12) by the particles to be sprayed on the surface of the cavity (11), and a step (B) for forming second dimples (13) by the particles to be sprayed, which second dimples are smaller than the first dimples (12), are provided. A treating method (a) and a treating method (b) where either step (A) or step (B) is carried out depending on the requirements, and a method (c), where only the first dimples (12) are formed by carrying out only step (A) are also provided.

Abstract: The present invention provides a casting die that can achieve the improved fluidity of molten metal and the improved ease release of castings from die. The casting die 10 comprises area of dimples D where a plurality of first dimples are formed in semispherical shape on the surface of the cavity 11 with no particular indication of direction and in a dispersed manner and where the ratio of communication is 80% or more, which ratio of communication is defined by the ratio of the number of the first dimples 12 that constitute the bound dimples 12b, which each comprise one or more of the dimples, to the total number of the first dimples 12. So, in the area of dimples D a number of bound dimples 12b that work as short flow-channels that have no particular indication of direction are randomly formed, thus improving the fluidity of the molten metal.
