A mold for injection molding is composed of a first mold(100) having a first molding surface(120) with a recessed shape; and a second mold(200) formed with a second molding surface(220) with a bulged shape and separated with a predetermined gap to form a cavity(210) between the first and second molding surfaces. The second mold comprises plural unit molds detachably installed, and the second molding surface is formed with projections(230) having a predetermined shape on the second molding surface. The projection is shaped like a lattice on the second molding surface.
