Description of function:
The unit is linked to the machine frame via a nozzle plate. The
standard version of the closing plate is supported so that the
weight forces are transmitted to the machine frame.
The sliding plates of the closing platen must be
lubricated every 2,500 working hours.
The closing force is exerted via two closing cylinders. The
extremely stable construction of the square closing and
nozzle plates ensures ideal closing force distribution.
The quick-action cylinder provides for a rapid closing process
and at the same time ensures senstive mould protection.
The closing force is developed via the piston surface of the
piston rod, which permits the full closing force buildup at a
hydraulic pressure of 210 bar (3045 pai). This intentionally
low closing pressure ensures the long life of the seals and
guiding devices in the guiding sleeves.
The piston rod is guided in the nozzle plate. We have given
particular attention to the distance to the seals in order to
safeguard the intactness of the hydraulic seals in case of
damage to the piston rods during siting.
A clearance is put between the seals and the guiding device;
leaking oil is collected there and flows off through a leakage
oil duct.
The ejector is a double-action hydraulic cylinder and was
integrated into the square construction of the closing plate.
