Abstract
A molding die includes a fixed die, a movable die movable toward and away from the fixed die, a first slide core slidable in sliding engagement with the fixed die, and a second slide core having a presser for pressing the first slide core when the second slide core is held in pressing contact with the first slide core. The fixed die, the movable die, the first slide core, and the second slide core jointly define a cavity for molding a product. The presser includes a reactive force plate for producing reactive forces against the pressure of a molten material introduced into the cavity.
