at least two separate mold plates each having:
a mold insert socket with a mold insert attached in the mold insert socket,
mutually opposite and parallel abutting side faces defining the thickness of the mold plate, and

wherein the guide bushings and the mold insert socket of at least one mold plate of the at least two separate mold plates are interconnected via one or more connection plates each extending parallel to the abutting side faces and having a thickness of less than half the at least one mold plate of the at least two separate mold plates thickness.
