PURPOSE: A mold for injection-molding a product of different colors and a method thereof are provided to improve joint strength by forcing different material to infiltrate to each other and solidifying them. CONSTITUTION: A mold for injection-molding a product of different colors comprises first and second molding blocks(11,12), a die(10), a slide mold(20), and first and second gates(16,17). The first and second molding blocks are arranged in a line. The die comprises first and second cavities(14,15) formed between the first and second molding blocks. The slide mold is formed between the first and second molding blocks, and contracted and moved by a pressure more than a certain level. The first and second gates guide first and second mold materials injected from an injection molding machine to the first and second cavities, respectively.
