An injection molding machine is provided to decrease defects such as disconnection of a circuit pattern, and to improve quality of a liquid crystal display device by restricting step or burr in an injection molded product. An injection molding machine(100) includes a lower mold(130), an upper mold(120) lifting up and down against the lower mold, a sliding core(140) sliding in the lower mold and having a forming space with the lower mold and the upper mold and a seating part composed of an inclined operation surface and a lower surface, and a locking block(125) lifting with the upper mold and having a counterpart surface contacted to the inclined operation surface to slide the sliding core and a contact surface contacted to the lower surface at the bottom dead center. The contact surface is contacted discontinuously to the lower surface, and an injection molding unit(150) is formed between the upper mold and the lower mold to inject material to the forming space.
