Specific embodiment
The following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments, convenient for this hair is well understood It is bright, but they limiting the invention.
In injection process, macromolecule melt enters type chamber by cast gate by screw rod rotary squeezing.Capacitive pressure sensing Device is mounted on to be had the phenomenon that gate location is observed that: melt enters type chamber, namely start injection at the time of, injection/guarantor At the time of crush-cutting changes, at the time of pressure maintaining terminates cooling start.It can also be surveyed in the position that type chamber end namely plastics finally fill Obtain cavity pressure change information abundant: at the time of sand off, at the time of injection/pressure maintaining switches, pressure maintaining terminates cooling and starts At the time of, open time.Particularly with the longer product of melt flow path, it is particularly important to increase measurement point in type chamber end.
As shown in Figure 1, installing first pressure sensor 1 and second respectively in the nearly gate area of product and type chamber end Pressure sensor 2.First pressure sensor 1 is mounted on nearly cast gate and is located at melt flow path side, near selection cast gate When measurement position, for being difficult to install the mold of sensor at nearly cast gate, preferably first pressure sensor 1 is mounted on and is being flowed In preceding 1/3 range in path.For the product that cross section changes greatly, it should preferentially select cross section maximum namely setting time Longest region.Wherein, first pressure sensor 1 and second pressure sensor 2 are capacitance pressure transducer,.
As shown in figure 3, injection molding process is the dynamic circulation process that can be divided into several important stages.Mould Process of injection molding is divided into 5 feature apparent stages by 6 characteristic points on cavity pressure curve.The specific meaning of these characteristic points Justice is as follows:
1, characteristic point 1.Screw rod in barrel is continually advanced anteriorly, and injection moulding process starts.At this point, plastic melt not yet connects Force snesor is pressed, the measured value of cavity pressure sensor is 0.
2, characteristic point 1-2.Plastic melt is injected into mold cavity under the promotion of screw rod, by the running gate system of mold Interior, after plastic melt contacts cavity pressure sensor, pressure sensor measures cavity pressure.
3, characteristic point 2.Plastic melt touches cavity pressure sensor.Hereafter, with the progress of injection process, die cavity pressure The pressure value that force snesor measures constantly increases.
4, characteristic point 2-3.The stage is the mold filling stage.At this point, cavity pressure constantly increases, the size of stuffing pressure depends on In mould intracavity wall to the flow resistance of plastic melt.
5, characteristic point 3.The point means plastic melt filled up completely with mould type chamber, is mold filling stage and packing stage Ideal switching point.
6, characteristic point 3-4.The stage is packing stage.After plastic melt has filled mold cavity, injection molding machine needs Continue to apply pressure to mold, constantly compresses plastic melt, to ensure that plastic melt is filled by complete compacting, and will not There is a phenomenon where melts to flow backwards.In this stage, cavity pressure increases rapidly, and obtains maximum value.
7, characteristic point 4.With the continuous progress of pressure maintaining, cavity pressure has reached maximum value, and size is mainly by pressure maintaining pressure Power and plastics physicochemical characteristic codetermine.
8, characteristic point 5.The point is gate solidification point, and after gate solidification, melt is no longer flow into or flows out mold cavity.Together When, due to the solidification shrinkage of plastic melt, cavity pressure constantly reduces.
9, characteristic point 6.Plastic products solidify completely, and start to shrink, and it is 0 that cavity pressure returns again, injection moulding week Phase completes.
After capacitance pressure transducer, measures the signal of pressure, it is converted into analog signal by A/D, is amplified by signal Device is suitably amplified collected data, the modules of Input Software system, carries out data processing and signal output, most After obtain the first cavity pressure curve 1a and the second cavity pressure curve 2a.The cavity pressure curve (measured near cast gate One cavity pressure curve 1a) it is recorded from beginning packed type chamber.During packed type chamber, pressure uniformly rises.Second type chamber The starting point of pressure curve 2a means the time point at melt arrival type chamber end.It can be seen that macromolecule melt is in type chamber Internal Real Flow Field rate.At the same time, injection molding machine executes pressure maintaining switching action, and the cavity pressure into cast gate has and significantly mentions It rises, also has corresponding response in type chamber end.The medium-sized intracavitary melt of pressure maintaining handoff procedure has carried out compacting and feeding process, until Pressure reaches peak value.Dwell pressure is withdrawn from after pressure to reach to peak value, begins to cool process.
The present invention is optimized by CAE analog simulation, and reliable type chamber pressure is obtained after the Rational Simplification in calculating simulation Force curve recommendation obtains optimal cavity pressure curve with this.Such as using standard tensile test specimen as product, the material that uses for PP is obtained through CAE analog simulation, and optimal processing parameter is injection time for 0.15s, and melt temperature is 260 DEG C, and mold temperature is 50 DEG C, dwell pressure 34MPa, dwell time 8s.With this group of data mart modeling, then recorded according to capacitance pressure transducer, Obtained cavity pressure curve is best cavity pressure curve.
As shown in figure 4, cavity pressure integrated value is integral of the cavity pressure to the time.By obtaining forming whole process or portion Pressure curve area value in subregion, can apply cavity pressure curve integrated value.It is given on section [a, b] for one Nonnegative function f (x), we want to determine the area of figure folded by curve representated by f (x) and X-coordinate axle, we can be by this It is denoted as:Using this principle, arbitrarily one section in selection section [a, b], as long as the shaped form that experiment is obtained Cavity pressure integrated value is compared with best cavity pressure curve cavity pressure integrated value, then according to the essence of required processing Degree determines a value ε (i.e. calibration tolerance), as long as | SEmpirical curve-SAim curve| < ε, so that it may guarantee parts quality qualification.
In addition, also the first cavity pressure curve is compared with optimal cavity pressure curve;If the first cavity pressure is bent Line and optimal cavity pressure curve co-insides, then without adjusting molding proces s parameters;If the first cavity pressure curve and optimal type chamber Pressure curve is not overlapped, then the influence according to injection rate in molding proces s parameters to cavity pressure curve, molding proces s parameters Influence and note of the dwell pressure to cavity pressure curve in influence of the middle mold temperature to cavity pressure curve, molding proces s parameters Influence of the dwell time to cavity pressure curve in technological parameter is moulded, analyzing leads to the first cavity pressure curve deformation Factor, the factor be injection rate, mold temperature, dwell pressure, in the dwell time any one or more parameter it is bigger than normal or It is less than normal;Corresponding technological parameter is adjusted for the factor, makes the first cavity pressure curve and optimal cavity pressure curve co-insides.
As shown in figure 5, influence of the injection rate to cavity pressure curve:
With the raising of injection rate, trend that the oriented upper left of cavity pressure curve gradually deviates.The raising of injection rate The time that the type chamber of reducing is full of, the time for reaching pressure peak move to left therewith.The raising of injection rate also makes cavity pressure Peak value constantly increases, and skyrockets after injection rate is more than certain numerical value;This filling velocity of explanation at this time has made Melt is instantaneously full of type chamber, becomes before V/P conversion and produces the high pressure of moment type is intracavitary.
As shown in fig. 6, influence of the mold temperature to cavity pressure curve:
With the raising of mold temperature, trend that the oriented upper right of the right-hand component of cavity pressure curve gradually deviates.This says Bright cooling rate slows down with the raising of mold temperature, and cooling time increases, and curve right-hand component curvature is gradually reduced, cooling Rate gradually decreases.Curve left-hand component essentially coincides, and starts the time of filling, the time of V/P switching and cavity pressure top Peak illustrates influence very little of the variation of mold temperature for melt filling almost without changing.The cavity pressure value of curve It is gradually increased with the raising of mold temperature.
As shown in fig. 7, influence of the dwell pressure to cavity pressure curve:
With the increase of dwell pressure, trend that the oriented upper right of cavity pressure curve gradually deviates.Obviously, cavity pressure peak The change of value and dwell pressure are in the relationship of strong correlation.In other words, the size of cavity pressure peak value is mainly determined by dwell pressure, The influence factor of next is respectively injection speed, part shape, material property, mold temperature, melt temperature etc..The type chamber of curve Pressure integrated value is similar with the variation of pressure peak, and numerical values recited is the increase with dwell pressure and increases.
As shown in figure 8, influence of the dwell time to cavity pressure curve:
With the increase of dwell time, cavity pressure curve has the tendency that gradually deviating to the right.It is identical as dwell pressure, The dwell time influence curve form cooling procedure that mainly partial trace declines on the right, determines melt in the hair of cooling procedure Raw metamorphosis has little effect technical process before.
The content that this specification is not described in detail belongs to the prior art well known to professional and technical personnel in the field.
