With the closing movement of the mould, the control bar
moves through the control plate into the latch housing until
it is stopped at the catches.
In this position, the control bar presses on catches and pushes
the latch housing connected to ejector set back to the initial
position.
When this position has been reached, the catches move into
the cams of the guide plate and the control bar moves by the
set safety travel into its final position.

- The early returns are to be arranged symmetrically, parallel
and square to the mould guide.
- All screws are to be secured with spring washers or with
adhesive Z9094.
- It should be ensured that ejector set ends flush with the
other mould plates and at the end faces on both sides.
Preparatory work
- Match the length of the catch housing, control plate,
spacer and control bar in accordance with the mould design,
and shorten if necessary. The hardened layer on the side faces
must first be ground down.
- Drill mounting holes in conrol plate, catch housing, spacer
and control bar. Drill mounting holes for conrol plate, latch
housing, spacer and control bar in the mould plate. The parallel
dowel holes for the latch housing must be made in the ejector
set at the same time.
Mounting and adjusting
- Mounting with mould assembled.
- Fully install injection mould with guide components. To
do this, place ejector set against the mounting plate and
secure it against movement (e.g. using screw clamp).
- Screw on catch housing and secure with pins. Watch out for
position of catches. Insert the edges, which are chucked at
the sides, downwards into the latch housing.
- Insert the control bar loosely. Attach control plate and
screw on loosely. Adjust control plate to "no play"
by placing against the catches, then secure with pins and
tighten screws until position is fixed.
- Pre-position control bar and with spacer screw loosely onto
the mould plate.
- Open mould parting; pre-tighten ejector set until it comes
to bear against the mould plate and secure it so that it cannot
move (e.g. using screw clamps).
- Finely adjust the ejector stroke which is to be secured
with the aid of gauge blocks.
- Place all the control bars uniformly and without play against
the catches and bolt them fixedly parallel to the mould guide
and secure with pins.
- Check correct functioning manually.
