The invention discloses an injection molding mold used for molding a double-color product and an injection molding method using the same. The mold comprises a mold base provided with a moving mold and a fixed mold, wherein the fixed mold is corresponding to a double-color injection device. A first color part mold division cavity used for forming a product is arranged between the moving mold and the fixed mold and a mold cavity part of the moving mold is provided with a moving mold active embedded piece. A slide block is arranged between the moving mold and the fixed mold and at least a secondcolor part mold cavity for forming the product is arranged between the opposite end face of the moving mold active embedded piece and the slide block. The moving mold active embedded piece and the slide block are connected with a drive device and perform reciprocating movement perpendicular to the molding direction under the action of the drive device. Therefore, sidebyside colorant match can be achieved only by using a set of molds by once mold open namely the molding of a plastic product with double color or double material along the extension direction of the product. Moreover, the double-color product can be molded through injection without a special double-color injector so as to reduce the additional manufacture cost of the product.
