Abstract: An injection-molding tool comprising at least two separate mold plates each having a mold insert socket with a mold insert attached in the mold insert socket. Each mold plate have mutually opposite and parallel abutting side faces defining the thickness of the mold plate and a number of mutually aligned guide bushings forming through holes adapted for axially sliding one of the mold plates with respect to the other on a common guide pin in a direction perpendicular to the abutting side faces of the mold plates. The guide bushings and the mold insert socket of at least one mold plate am interconnected via one or more connection plates each extending parallel to the abutting side faces and having a thickness of less than half the thickness of the mold plate.

Abstract: A mold insert having a main body including a first surface and an opposed second surface, the first surface defining a plane. The mold insert also has a mold core extending from the first surface and a gas inlet port connectable to a supply of pressurized gas. Further, the mold insert has two or more gas outlet ports arranged to direct a gas flow towards an uncovered surface of an injection molded item located on the mold core, after the mold core and the mold cavity are separated from each other. Further, the mold insert has a gas conduit system extending inside the main body connecting the two or more gas outlet ports with the gas inlet port. Each of the two or more gas outlet ports are arranged through the first surface. The gas conduit system is provided in the main body below the first surface.
