1. Insert tubular hexagon spanner (a) into the hexagonal
cutout in the piston (pos. 7.3) and hold it in position by
using a wrench to avoid rotation of the piston (pos. 7.3).
2. Insert the allen key (b) through the tubular hexagon
spanner (a) to unscrew and to dismantle the screw
(pos. 7.6).
3. Insert the valve pin (pos. 17) carefully and without tilting.
Apply axial load only. Tilting or bending caused by lateral
load must be avoided. Slowly push the valve pin through
the manifold and the valve pin guide in the tip insert
of the nozzle until the head of the valve pin sits at the
bottom of the valve pin retainer (pos. 7.7).
4. Screw the screw (pos. 7.6) in again by using the allen
key (b) and the tubular hexagon spanner (a). Tighten
with matching torque. See chapter „9.4 Tightening
torques for screws to fix the valve pin in the valve pin
retainer“.
When the hot runner system is not filled the valve pin can be installed
in cold condition.
If the hot runner system is filled it must be heated to operating tem
-
perature before the valve pin is installed.
NOTE!
Connected power supply during installation
Risk of deadly electric shock or severe injuries due to live compo-
nents.
• The hot runner system and the mould have to be disconnected
from the voltage source during installation.
HAZARD!
Pressurised systems
During installation all hydraulic or pneumatic supply lines must be de-
pressurised.
•
Injuries caused by flying parts or "whipping" hoses.
• Injuries to eyes caused by escaping pressurised liquids
WARNING!
The installation process described below is valid for the following drive unit versions:
• Drive unit integrated in clamping plate (version 1)
• Drive unit integrated in clamping plate (version 2)
• Drive unit placed on manifold (coupled)
• Drive unit placed on manifold (screwed-on)
The example shows a drive unit which is integrated in the clamping plate.
