Title: PISTON FOR DIE-CASTING MACHINE
Abstract:
A piston for a die-casting machine, in particular of the cold chamber type, comprises a stem, an axial support pin that extends from the distal end of the stem, and a piston head. The piston head is secured to the axial support pin by means of first radial blocks, each of said first radial blocks being received in a respective housing formed by a first radial pass-through opening formed in the side wall of the piston head and by a first block seat formed in a front portion of the support pin. The first radial blocks are held in the respective housings by means of an annular band mounted on the piston head around the first radial pass-through openings.
