PURPOSE: An injection mold is provided to prevent damage to or deformation of an ejecting pin due to vertical load by the reduction in the aspect ratio of an ejecting pin. CONSTITUTION: An injection mold comprises an outer block, an inner block(200), a mold core(300), an ejector(400), and a movable unit(500). The outer block is fixed to an injection molding machine. The outer block is divided into upper and lower dies(110,120). The upper and lower blocks(210,220) of the inner block are mounted on the upper and lower molds to be replaceable. A molded product(10) with a molded portion of several-ten or several-hundred micrometers size is molded in a cavity(310) of the mold core. The ejector discharges the molded product of the cavity by the linear movement. The movable unit is moved up and down by the pneumatic pressure. The movable unit runs the ejector.
