20090071326 | Piston For Cold Chamber Die-Casting Machine - The object of the present invention is a piston for cold chamber die-casting machines comprising a body and at least one sealing band mounted around said body, wherein said body and said band are provided with coupling means suitable for concurrently obtaining both an angular locking and an axial locking of the band to the piston body. | 03-19-2009 |
20140123848 | PISTON FOR A DIE-CASTING MACHINE - A piston for a die-casting machine, in particular with a cold chamber, comprises a stem which extends from a proximal end to a distal end along a piston axis and a piston head which extends from the distal end of the stem and which has a side wall with at least one sealing area suitable to form a seal on the wall of said container of the press. A lubrication circuit suitable for favouring the sliding of the piston comprises first lubrication ducts made in the stem and ending at the distal end of said stem, and second ducts made in the piston head, fluidically communicating with said first ducts and coming out in the lateral wall at least in correspondence with said sealed area. | 05-08-2014 |

20150096439 | PISTON FOR COLD CHAMBER DIE-CASTING MACHINES - A piston for cold chamber die-casting machines includes a piston body terminating at the front with a frontal surface pushing molten metal and at least one ring seat made around the body suitable to house a respective sealing ring. An annular distribution channel is made in an intermediate annular portion of the bottom surface of the ring seat, which communicates with the frontal surface of the piston through at least two communication holes made in the piston body for flow of molten metal into the distribution channel, under the ring. The communication holes are inclined in relation to the piston axis and have a through section which increases towards the distribution channel. | 04-09-2015 |
