An internal core for an injection mold tool is provided to improve the assembly performance and reduce the cost by dividing the internal core by the wall component part and mutually combining the tapered and uniform wall component parts. An internal core(10) for an injection mold tool comprises a tapered wall part; and a uniform wall part. The tapered and uniform wall parts horizontally divide the internal core along a surface passing through the internal core at a delineation line(16) separating the uniform and tapered wall parts. The tapered and uniform wall parts are additionally manufactured to form a tapered wall component part(14) and a uniform wall component part, and formed with a necessary shape and composition. The internal core contains a unit for combining the tapered and uniform wall parts along the delineation line to form the internal core. |
