Chamber 8 can be loaded pressure.For this provides the valve 16 for being configured to reversal valve, otherwise the valve so switches so that it is present in top
Pressure in chamber 8 is discharged in fuel tank, otherwise so switching so that pressure-loaded is carried out to upper chamber 8 by pump.By
This, hydraulic cylinder 8 can when closing unit 1 is closed auxiliary electric axle 7.
Fig. 4 is shown similar to a kind of implementation method of the implementation method of Fig. 3.Implementation method difference with Fig. 3 is,
Electronic axle 7 is replaced with other hydraulic cylinder 12.In the present example, the hydraulic cylinder 12 is configured to single-acting, i.e., thereon
Portion's chamber 15 is not loaded pressure.
The lower chamber 13 of the other hydraulic cylinder 12 is connected accordingly by valve 16 with pump 10.By the additional of valve 16
Position, can additionally with pressure-loaded lower chamber 13.

When, it is released from by the blocking of the check-valves 24 that can be unlocked and the pressure in the upper chamber 8 of hydraulic cylinder 4 can unhinderedly passes through
The check-valves 24 that can be unlocked is unloaded.
Mould can be made to passively maintain closing by the check-valves 24 that can accordingly unlock, this for example can be in the mould of spring pre-tightening
It is favourable in tool.
Pressure sensor 26 in the other lower chamber 13 of hydraulic cylinder 12 is sufficiently used for the weight according to mould
And opening stroke adjusts on the preload pressure of corresponding optimum accumulator 5.
Loading of the weight of movable mold cramping plate 3 in the open position according to accumulator 5 is more or less described
The piston force of hydraulic cylinder 4 and/or the other hydraulic cylinder 12 keeps.If the pressure in cylinder is in machine open mode
Minimum value or even zero, then that is total weight is kept by cylinder with therefore accumulator pretension in practice.
Therefore, it is necessary to pass through the device 11 for loading and unloading accumulator 5 in machine start or after more mold exchange
Carry out so long ground load or unload accumulator 5 with corresponding apparatus for controlling pump, until the display minimum pressure of pressure sensor 26
(such as：20bar).
Certain minimum pressure is needed to ensure：
- other the hydraulic cylinder 12 be reliably filled oil and will not due to accumulator 5 cross loading and even in work
Plug side formed hole and
- can compensate for due to opening and closing process the pressure change that is inevitably produced in accumulator 5.
Because the hydraulic cylinder 4 and the variable-volume and accumulator package of the other hydraulic cylinder 12 on stroke
Quantity, the volume of accumulator 5 and loading are known, so it is also known that the hydraulic cylinder 4 and the other hydraulic cylinder 12
The change of maximum possible of the pressure on stroke in lower chamber 6 and 13.Therefore, it is optimal also dependent on climb displacement is opened
Minimum pressure and may be completely independent of and most preferably load accumulator 5 when front opening stroke.
Sample calculation：
- by the pressure change in the whole shift motion calculating accumulator 5 of hydraulic cylinder 4 and 12：Such as 20bar；
- maximum shift motion is 1000mm；
- desired minimum pressure in the lower chamber 6 and 13 of hydraulic cylinder 4 and 12 is 10bar；
Minimum pressure in-cylinder logically appears in the state for completely closing (hydraulic cylinder 4 and 12 is moved fully into)
In, because accumulator 5 is at utmost loaded and therefore by hydraulic cylinder 4 and 12 is undertaken more power herein.
Based on described it is assumed that in completely closed state, being acted in the lower chamber 6 and 13 of hydraulic cylinder 4 and 12
Minimum optimization pressure be 10bar, in full opening of state for 30bar (on condition that all 4 hydraulic cylinders 4 and 12 have phase
Same piston diameter；Hydraulic cylinder 4 and the other hydraulic cylinder 12 have different-diameter as described, then must mutually be considered as the face
Product ratio).Thus the ideal load pressure under any stroke can be calculated.
Similar computational methods can also be used for during remaining has an implementation method of electronic axle 19.Exist instead of pressure sensor 26
This usable torquemeter or strain gauge, the power of presence can be respectively measured by them.
Oil is used as hydraulic medium in all embodiments.Accumulator 5 is configured to multiple bladder accumulators.
But the utility model is not limited to implementation method shown here.The upper chambers of such as described other hydraulic cylinder 12
The upper chamber 8 of room 15 and the hydraulic cylinder 4 can each other hydraulic connecting (therefore the other hydraulic cylinder 12 is also double acting
).Additionally, accumulator 5 can be integrated in the lower chamber 6 of hydraulic cylinder 4.
