Stationary Clamp with Built-in Mechanical Lock
Highly reliable clamp with mechanical locking system maintains
the holding force even when the locking pressure is removed.

Features and Action Description
Mechanical Locking System

The mechanical locking systemprevents a mold from falling.
The built-in mechanical lock holds the mold with powerful holding force
Moldeven when the locking pressure drops to zero in case of piping damage etc.

Taper Ring

Spring<Lock Action><L oc k Ac tion >The taper ring expands to the tapered part of the clamp piston by
the lock hydraulic pressure and spring force. (Mechanical Locking).

Tapered Part

Ring Piston

Clamp Piston

Oil bath structure prevents the taper ring from sticking to the clamp piston.

<L oc k H ydraulic Pressure a t 0MPa>
The clamp piston maintains the locked state with the holding pressure
created by the mechanical locking system.

<Release Action><R elea se Ac tion >With the release pressure, the ring piston pushes up the taper ring toperform a smooth release action.

Cautions● Notes on Handling1）Close the mold after molding is completed.
● Failure to do so may result in mold dropping and injury.

7）Hold the clamp body when moving and removing the clamp.

and maintained by qualiﬁed personnel.
3）Do not handle or remove the product unless the safety
protocols are ensured.
① The machine and equipment can only be inspected or preparedwhen it is conﬁrmed that the preventive devices are in place.
② Before removing the product, make sure that theabove-mentioned safety measures are in place. Shut oﬀ thepressure and power source, and make sure no pressure exists8）Do not pour water or oil over the product.

● It may lead to malfunction or deterioration of the productand cause an accident.

③ After stopping the product, do not remove until theequipment cools down.
④ Make sure there is no abnormality in the bolts and respective
parts before restarting the machine or equipment.
4）Do not apply load to the clamp when at 0MPa.
【GWA/GLA】● In case of hydraulic source trouble, the clamp has holding
force with mechanical lock even when hydraulic pressure is
at 0MPa. However, do not apply load on the clamp at thisstate.
9）Do not disassemble or modify.
5）Do not touch clamps while they are working.
● Otherwise, your hands may be injured.

● If the product is taken apart or modiﬁed, the warranty will be
voided even within the warranty period.
10）Do not apply excessive force to clamps.
● The clamp may be damaged or deformed, resulting in
malfunction.

6）When changing a mold width, make sure to check theallowable protrusion amount.
● If using it with beyond allowable protrusion amount,excessive force is applied to the clamp which deforms or
damages the clamp resulting in falling of the mold andinjury. It may cause product malfunction or deterioration,
which may lead to an accident.

2）Lubricate grease periodically.
【GWA/GLA】● Lubricate grease from the grease nipple periodically (once a
year is recommended) to maintain clamp performance.
Especially when process water often splashes on theclamps, release operation failure is likely to occur.
In such cases, lubricate the clamps with grease more
frequently than recommended, if necessary.
