DEVICE FOR FASTENING ROD WITH A PISTON ON A HORIZONTAL INJECTION MOLDING MACHINE Russian patent published in 2019 - IPC B22D17/20 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgical production, in particular to the production of castings from non-ferrous alloys. Device for fastening the rod with a piston on a horizontal injection molding machine contains a hollow extension of the rod of the pressing mechanism, accommodating the rear part of the first rod with an annular stop and a disc abutting with the front end against said stop and contacting by its rear end with the bottom of the extension cavity. From the front end of the extension of the rod of the pressing mechanism, a cavity of smaller diameter is made, which is open into a blind cavity of larger diameter with upper longitudinal slots for accommodating the rear part of the rod with a spherical annular stop mated by its front part with a spherical front end of the cavity of a larger diameter extension, and by its the back part - with a spherical front end face of the washer, propped against the back end into the front end face of the disc.

EFFECT: improved durability of pistons and extrusion chambers with simultaneous improvement of the quality of castings in terms of porosity and surface hardness is ensured.
