DEVICE FOR SECURING ROD WITH PISTON ON HORIZONTAL INJECTION MOULDING MACHINE Russian patent published in 2017 - IPC B22D17/10 

FIELD: metallurgy.

SUBSTANCE: device for securing the rod 1 of the piston 2 on the pressing mechanism of the horizontal injection moulding machine comprises a coupling 3 connected to the outer surface of the union nut 4 located on the front part of the rod 5 of the pressing mechanism of the machine. The front part of the coupling covers the rear part of the rod 1. A disk 7 made with cavity 9 and radius peripheral surface is placed between the ends of the piston rod 1 and rod extension 5. The piston rod 1 has a circular stop 6 contacting with radius cavity made on the coupling and with the disc radius peripheral surface, the rod 1 has an annular groove 10 extending from the front end of the coupling to the front end of the circular stop 6.

EFFECT: reduced skewing of the rod with piston in the pressing chamber from axial displacement of the machine press mechanism, and reduced wear of the piston and the pressing chamber.
