Zusammenfassung:	PURPOSE: An injection molding device is provided to prevent the generation of a weld line by enhancing the fluidity of polymer resin in an injection mold. CONSTITUTION: An injection molding apparatus(10) comprises first to third molds(20~40), a guide unit(50), and heating and cooling units(60). The first mold is supported on a first fixing plate(11). The second mold is coupled and separated to/from the first mold. The second mold is coupled to the first mold to form a cavity(12) for injection molding. The third mold is coupled and separated to/from the second mold. The guide unit couples and separates the first to third molds. If resin is put into the cavity, which has been by the coupling of first and second molds, the heating and cooling units heat the second mold. If the resin of the cavity is cured, the heating and cooling heats cool the second mold.
