Method for producing a mould segment of a vulcanizing mould, mould segment, and vulcanizing mould

A method for producing a mold segment of a vulcanizing mold for a pneumatic vehicle tire, the mold segment being configured to form the profiling of a tread of the tire, the method comprising:

• providing a metallic base part having a mold side;
• milling a rib skeleton into the mold side of the base part, the rib skeleton comprising ribs arranged and profiled so as to correspond with channels of the profiling of the tread in which said channels encircle or delimit profile elements of the profiling of the tread;
• building inserts with frame parts using an additive manufacturing process;
• and
• inserting the inserts into the rib skeleton, wherein the ribs of the rib skeleton in combination with the peripheral frame parts of the inserts form overall ribs that define the channels encircling or delimiting the profile elements of the profiling of the tread.
