Abstract
Provided is a mold manufacturing method with which the requirement of a wide variety of products in a small lot can be satisfied. A cutting step includes forming, through cutting, mold matching surfaces in respective upper and lower molds and forming, through cutting, cavities Cand Cin the respective upper and lower molds with the mold matching surfaces being references. A mold matching step includes: measuring at least three points PUtothat are not located on a same straight line and that are located on the mold matching surface of the lower mold placed on a placement surface; causing recognition of Z coordinates of these respective points; measuring at least three points PLtothat are not located on a same straight line and that are located on the mold matching surface of the upper mold gripped by a gripping arm; causing recognition of Z coordinates of these respective points; and subsequently performing mold matching with the mold matching surfaces SmU and SmL of the upper and lower molds being oriented to be kept parallel to each other.
