This occurs in the following way, that is, in process is worked in mold clamping force mechanism, utilize the motion of closing unit to apply the balancing force (Offset-Kraft) contrary with mold clamping force direction.Here, any mechanism that can react on mold clamping force mechanism of closing unit can be used as motion.
Can set in the moulding process in modern times, especially injection press process, repeatedly open and then again close half module.Will point out in the sense that, mold clamping force also can be negative value, and such mold clamping force just becomes tensile force.
Define other favorable embodiment of the present invention in the dependent claims.
Here, " or " should be understood as all the time " being included ", that is, by " or " combination of separated possibility be naturally can expect and look specifically useful.Such as, quick mechanism for rapid open and close closing unit can be used as motion.Under normal conditions, although quick mechanism is designed for the power much smaller than clamping pressure mechanism.However, quick mechanism can react on mold clamping force institution staff like this, makes to be raised on minimum force by this mold clamping force mechanism applied force, can accurate opened loop control or closed-loop control mold clamping force mechanism on this minimum force.
Hydraulic mould-matching force mechanisms itself can be another example of motion.Because there is the first Room and the second Room in the mold clamping force mechanism being configured to hydraulic cylinder, and when producing mold clamping force by the pressure in raising second Room, the pressure improved in the first Room just can make in the second Room for needed for specified mold clamping force rated pressure raise, the rated pressure therefore in the second Room fall into can precise closed-loop control or opened loop control scope among.
Can certainly combination be used, in other words, such as, apply a part of balancing force by quick mechanism, and apply another part balancing force by mold clamping force mechanism itself.
Balancing force can be applied on movable mold cramping plate or in clamping pressure mechanism itself.
Be transported to as much as possible to make mold clamping force mechanism and can carry out, among the scope of accurate opened loop control or closed-loop control, can specifying to this mold clamping force mechanism, substantially applying for the masterpiece of the maximum permission of motion is balancing force.Particularly when specified mold clamping force is smaller, thus when opened loop control or closed-loop control mold clamping force mechanism become difficult, specify like this.Can specify when mold clamping force height, regain balancing force.
Can specify, in order to closed-loop control mold clamping force, determine mold clamping force absolute value, this mold clamping force absolute value is equivalent to the actual power acting on movable mold cramping plate substantially, and uses mold clamping force absolute value as the feedback parameters of closed-loop control.Can technique of arranging production be simplified thus, because curves of kinetic feature or power indicatrix can be determined with absolute value by calculating or simulating in advance, and then really can be described by closing unit.
Usefully at this can be, not only measure the mold clamping force applied by mold clamping force mechanism or the balancing force applied by motion, and measure at least one beam, movable mold cramping plate or movable mold cramping plate together with the holding power caused by quality of half module or at least one frictional force, and the power measured by considering when determining mold clamping force absolute value.
In order to the gravity effect compensating such as half module in vertical closing unit can specify, by the motion by closing unit at least one beam described or movable mold cramping plate remained on constant height together with half module and measure for this reason by motion applied force, measuring holding power.
Can specify at this, utilize at least one hydraulic cylinder of motion pressure sensor or multiple pressure sensor determination holding power.
Thus, can specify in the particularly preferred embodiment of one, utilize the second pressure sensor determination holding power of the first pressure sensor in the first indoor of at least one hydraulic cylinder described and the second indoor at least one hydraulic cylinder described, wherein, the value of reaction force is determined by the difference after the effective piston area weighting of utilization of the measured value of the first pressure sensor and the second pressure sensor.Although the pressure of one of them indoor is much smaller than the pressure of another indoor under most running status.But still accurately can carry out opened loop control or closed-loop control by the present invention, the effect making this little also can produce great distortion.
Can specify in a preferred embodiment, measure at least one frictional force described of the adhesive force form of at least one beam described or movable mold cramping plate.
This can occur like this, namely, in order to measure adhesive force, measure the gravity of at least one beam described or movable mold cramping plate, by the motion of closing unit, at least one beam described or movable mold cramping plate are remained on constant height, measure the reaction force that for this reason applied by motion, and by the difference determination adhesive force of reaction force and gravity.At this advantageously, before assembling closing unit, crane is such as utilized can to measure the gravity of beam or movable mold cramping plate.The same with before for described in holding power, can measure the reaction force applied by motion, difference is do not have half module to be arranged on movable mold cramping plate in this case.With regard to this embodiment, suppose the existence of half module between movable mold cramping plate and beam or the adhesive force occurred between beam and guider only have little impact.The impact of weight on adhesive force of half module can certainly be detected by measuring technique.But, must be known or measure the weight of half module to this.
Another kind of particularly preferred embodiment can be, measures at least one frictional force described of the force of sliding friction form of at least one beam described or movable mold cramping plate.
Here, the gravity of at least one beam described or movable mold cramping plate advantageously can be measured before assembling closing unit.Can measure motoricity to be similar to the mode of having advised for reaction force equally.The Action of Gravity Field of half module is similar to and plays for such described by adhesive force.
At least describe the power that three kinds of diverse ways are used for determining to make absolute mold clamping force distortion.Can individually with these methods of united application.At this, those skilled in the art can determine that under what circumstances (technology characteristics, the closing unit of vertical or level) any method is significant, or any power of distortion that causes has larger impact.
Have nothing to do with the accurate work principle of opened loop control or closed-loop control, the present invention is based on such understanding: can within the scope of opened loop control or closed-loop control mold clamping force mechanism very well by being present in that motion on closing unit will be held in by trying hard to keep of applying of mold clamping force mechanism.

Other advantage of the present invention and details draw by accompanying drawing and affiliated accompanying drawing.Accompanying drawing is as follows:
Fig. 1 illustrates the diagrammatic side view of the closing unit of injection (mo(u)lding) machine, there is compacting gap between each half module,
Fig. 2 illustrates the view corresponding to Fig. 1, and closing unit is completely closed,
Fig. 3 illustrates that closing unit is in the diagrammatic side view allowing to measure in the position of holding power, and

Detailed description of the invention
Purely in FIG schematically show a vertical closing unit 1.This closing unit has a pressure mechanism 3, and this pressure mechanism can apply mold clamping force to movable mold cramping plate 2 by beam 6.A locking mechanism 13 is provided with in order to lock movable mold cramping plate 2 and beam 6.In the unlocked state, can utilize quick mechanism 4 that movable mold cramping plate 2 is moved.
Opened loop control or closed-loop control is carried out by an opened loop control or closed-loop control device 5 pairs of pressure mechanisms 3 and quick mechanism 4.The shown connection between quick mechanism, opened loop control or closed-loop control device and mold clamping force mechanism is schematic diagram certainly purely.
Not only pressure mechanism 3 but also quick mechanism 4 all have hydraulic cylinder 8.
In the present embodiment, hydraulic cylinder structure for quick mechanism 4 and pressure mechanism 3 similar.The difference of each hydraulic cylinder 8 is only its stroke and effective piston area thereof, depending on specific requirement.
Hydraulic cylinder 8 has the second Room 12 of first Room 10 and a bar side respectively, and these rooms can be loaded different pressure respectively.The hydraulic connecting of cylinder is prior art, so there is no draw in detail.First Room 10 and the second Room 12 of each hydraulic cylinder 8 are all furnished with the first pressure sensor 9 or the second pressure sensor 11 for measuring hydraulic pressure in respective compartments.First pressure sensor 9 is also connected with opened loop control or closed-loop control device 5 with the second pressure sensor 11.For clarity, this does not draw in the drawings.When opened loop control or closed-loop control device 5 are designed to closed-loop control device, the first pressure sensor 9 and the second pressure sensor 11 are used for measured value feedback to be used for close loop control circuit.
In the case of fig. 1, between half module 7 and another half module 14, there is compacting gap.Be used for mold clamping force mechanism 3 by quick mechanism 4 with the masterpiece of maximum permission, in the second Room 12 of the hydraulic cylinder 8 of mold clamping force mechanism 3, produce minimum pressure.This is required for accurate closed-loop control.
Fig. 2 is similar to Fig. 1, and wherein, compacting gap is now closed.In addition, quick mechanism 4 reacts on mold clamping force mechanism.Carry out, until specified mold clamping force is so big to such an extent as to pressure that is that exist in the second Room 12 of the hydraulic cylinder 8 of mold clamping force mechanism 3 is enough large, to ensure accurate opened loop control or closed-loop control so always.
In a situation as shown in figure 3, the holding power (for supporting mold clamping force) applied by beam 6, movable mold cramping plate 2 and half module 7 in forming process is measured dividually by quick mechanism 4 and pressure mechanism 3.For this reason, locking mechanism 13 unlocks.Movable mold cramping plate 2 and the Part I of half module 7 is derived from by the sensor measurement holding power in the hydraulic cylinder 8 of quick mechanism 4.The Part II of beam 6 is derived from by the sensor measurement in the hydraulic cylinder 8 of pressure mechanism 3.Then holding power is defined as the first and second component sums.
Below illustrate that the power of being undertaken by the sensor in hydraulic cylinder 8 is measured: the effective area in the second Room 12 is slightly less than the effective area in the first Room 10.Therefore, the value utilizing the component measured by the difference determination holding power after effective area weighting of hydraulic pressure by being measured by the first pressure sensor 9 and the second pressure sensor 11.
In embodiment shown here, each power measured by the pressure sensor in hydraulic cylinder 8 is undertaken by described mode.But this is not definitely required because such as can from the room with corresponding less pressure complete relieving pressure, thus the pressure only in another room corresponding is used for exerting a force to hydraulic cylinder 8.
If the gravity of known movable mold cramping plate 2 and beam 6 (such as by utilizing crane to measure before assembling closing unit), then also can utilize and measure movable mold cramping plate or the adhesive force of beam 6 to above-mentioned similar method.This adhesive force is primarily of caused by the stiction occurred in the guider of movable mold cramping plate 2 and beam 6 and hydraulic cylinder.Measure reaction force with being similar to holding power, wherein must pull down half module 7.Then adhesive force can be determined quite simply by the difference of reaction force and gravity.
By can the absolute value of closed-loop control or opened loop control mold clamping force according to method of the present invention.Be depicted as corresponding close-loop control scheme in the diagram.At this, first set up dynamic balance by the following value acting on the power of mold cramping plate:
-the first fast turn of speed FE1 of utilizing the first pressure sensor 9 in the first Room 10 of the hydraulic cylinder 8 of quick mechanism 4 to determine.
-the first pressure FD1 of utilizing the first pressure sensor 9 in the first Room 10 of the hydraulic cylinder 8 of mold clamping force mechanism 3 to determine.
-the second fast turn of speed FE2 of utilizing the second pressure sensor 11 in the second Room 12 of the hydraulic cylinder 8 of quick mechanism 4 to determine.
-the second pressure FD2 of utilizing the second pressure sensor 11 in the second Room 12 of the hydraulic cylinder 8 of mold clamping force mechanism 3 to determine.
-utilize the pressure sensor of quick mechanism 4 to determine movable mold cramping plate 2 together with the gravity FB of half module 7.
-gravity the FH of beam 6 that utilizes the pressure sensor of mold clamping force mechanism 3 to determine.
-frictional force FR, wherein, depends on the circumstances and uses sliding friction or static friction.
The mold clamping force actual value FS-IST occurred as dynamic balance result and the mold clamping force rated value FS-SOLL set by operator are compared.The result this compared is supplied to again opened loop control or closed-loop control device 5 (being designed to closed-loop control device in this situation).This opened loop control or closed-loop control device affect governor motion 15, and this governor motion is the control valve for the hydraulic pressure in the second Room 12 of the hydraulic cylinder 8 in mold clamping force mechanism 3 in the above-described embodiments.
Pressure in all the other rooms of hydraulic cylinder 8 is also subject to similar opened loop control or closed-loop control mechanism certainly.Especially the closed-loop control for the first fast turn of speed FE1 and the first pressure FD1 is implemented like this, namely, if the pressure drop in the second Room 12 of the hydraulic cylinder 8 of mold clamping force mechanism 3 is below certain threshold value, just become difficult lower than accurate opened loop control during this threshold value or closed-loop control second pressure FD2, so just improve at least one power in these two power.
The mold clamping force that the close-loop control scheme proposed allows closed-loop control absolute.Its advantage the result from simulation or calculating can be directly used in arrangement technical process.Thus the series of experiments for optimizing clamping pressure indicatrix can be avoided in some cases completely.
Embodiment shown in the present invention is not limited to here.Such as also can apply the present invention in the closing unit of level.Equally also can apply the present invention to electromechanical closing unit, because the closed-loop control that may be deteriorated when mold clamping force is little of these closing units or opened loop control.
