Fig. 3 means the figure of control system of the injection (mo(u)lding) machine of one embodiment of the present invention.Control part 60 is processed the control program that is recorded in memory by CPU such as possessing CPU and memory etc., controls thus the action of line motor 28 and electromagnet 49.
Mould opens and closes handling part 61 and exports the signal of the electric current of the coil 35 that represents to be supplied in line motor 28 to line motor with electric current supply unit 71.Line motor with electric current supply unit 71 such as being consisted of by inverter that comprises a plurality of power models etc.Line motor is supplied with and opens and closes the corresponding electric current of signal that handling part 61 is supplied with from mould to the coil 35 of line motor 28 with electric current supply unit 71.Line motor is with being connected with dc source 80 on electric current supply unit 71.Dc source 80 is converted to the rectifier 82 of the diode of DC current etc. and makes from the capacitor 84 of the DC current smoothing of rectifier 82 outputs etc. and consists of by the alternating current with AC power 90.
Matched moulds handling part 62 represents to be supplied in the signal of electric current of the coil 48 of electromagnet 49 with electric current supply unit 72 output to electromagnet.Based on the detected value of mold clamping force sensor described later (for example strain transducer 55), the electric current of the coil 48 that is supplied in electromagnet 49 is carried out FEEDBACK CONTROL, so that mold clamping force becomes desired value.Electromagnet with electric current supply unit 72 such as being consisted of by inverter that comprises a plurality of power models etc.Electromagnet is supplied with and the corresponding electric current of signal of supplying with from matched moulds handling part 62 to the coil 48 of electromagnet 49 with electric current supply unit 72.Electromagnet has the direction of the DC current that changes the coil 48 that flows to electromagnet 49 and the function of intensity (size) with electric current supply unit 72.Electromagnet is with being connected with dc source 80 on electric current supply unit 72.
Then, the action of the injection (mo(u)lding) machine 10 of said structure described.The exercises of injection (mo(u)lding) machine 10 are carried out under the control of control part 60.
Then, control part 60 is controlled the matched moulds operation by matched moulds handling part 62.Matched moulds handling part 62 is supplied with DC current to the coil 48 of electromagnet 49, and adsorption section 51 is adsorbed in electromagnet 49.But this absorption affinity is passed to dynamic pressure plate 12 via bar 39, but produces mold clamping force between dynamic pressure plate 12 and fixation clip 11.Due to connecting rod 14 and mold clamping force elastic elongation pro rata, therefore as in Fig. 1 with as shown in double dot dash line, but the mover 31 of fixation clip 11 dynamic pressure plates 12, adsorption plate 22 and line motor 28 advances slightly.Gap delta 0 when being formed at gap delta 1 between rear fender 13 and adsorption plate 22 less than mold closing during matched moulds.
The resin filling of melting is in the die cavity space of the die device 19 of matched moulds state.If resin is cooling and curing, matched moulds handling part 62 is adjusted the electric current of supplying with to the coil 48 of electromagnet 49, and removes mold clamping force.Due to connecting rod 14 elasticity recovery along with the releasing of mold clamping force, so the mover 31 of dynamic model 16, adsorption plate 22 and line motor 28 retreats slightly.
Then, control part 60 opens and closes handling part 61 by mould and controls the die sinking operation.Mould opens and closes handling part 61 and supplies with electric current to the coil 35 of line motor 28, but dynamic pressure plate 12 is retreated.As shown in Figure 2, dynamic model 16 retreats and carries out die sinking.
Yet when removing mold clamping force in the matched moulds operation, mold clamping force can not drop to 0(zero at once due to the impact of the operating lag of electromagnet 49).The operating lag of electromagnet 49 is due to electromagnet 49(such as magnetic core 46 etc.) in the impact of residual magnetic force produce.
Therefore, mould opens and closes handling part 61 and forbids that the die sinking action is until detect mold clamping force below predetermined value by mold clamping force monitoring part 64, if detect mold clamping force below predetermined value by mold clamping force monitoring part 64, supply with electric current to line motor 28 and carry out the die sinking action.Thus, carry out the die sinking action under the lower state of mold clamping force, therefore can reduce the power consumption for the die sinking action, and can make the die sinking having stable behavior.
Then, describe processing based on the releasing of the mold clamping force of matched moulds handling part 62 according to Fig. 4.Following processing is putting on predetermined mold clamping force die device 19 afterwards and is carrying out before die sinking.
The electric current that Fig. 4 (a) expression is supplied with to magnet spool over time, Fig. 4 (b) expression is based on the mold clamping force of electromagnet over time.In Fig. 4, dotted line is illustrated in t constantly
0Current value is set as 0 situation, solid line is illustrated in t constantly
0With the situation of sense of current counter-rotating, the single-point line is illustrated in t constantly
1Keep the situation of current value.In either case, matched moulds handling part 62 is supplied with constant DC current I to the coil 48 of electromagnet 49
0Until moment t
0, produce thus predetermined mold clamping force P
0(dotted line diagram moment t in Fig. 4
0Data before).
Removing predetermined mold clamping force P
0The time, with as shown in dotted line, matched moulds handling part 62 can be at moment t in Fig. 4 (a)
0Block to the coil 48 of electromagnet 49 and supply with electric current.Moment t
0After, due to the interior no current flows of coil 48 at electromagnet 49, therefore as Fig. 4 (b) in as shown in dotted line, mold clamping force is decline gradually due to the impact of the operating lag of electromagnet 49.In magnetic core 46 grades of the operating lag of electromagnet 49 due to electromagnet 49, the impact of residual magnetic force produces.
And, removing predetermined mold clamping force P
0The time, with as shown in solid line, matched moulds handling part 62 can be at moment t in Fig. 4 (a)
0Make the direction counter-rotating of DC current, and make and produce predetermined mold clamping force P
0The DC current I of direction of opposite direction
1Flow to the coil 48 of electromagnet 49.Form to offset the magnetic field of the direction in magnetic field residual in electromagnet 49, to promote mold clamping force to descend as shown in solid line, therefore, can foreshorten to the stand-by period till die sinking in Fig. 4 (b).
Reciprocal DC current I
1Intensity (size) larger, the stand-by period till die sinking is shorter.Waiting time is shorter, and production efficiency is higher, and on the other hand, the decrease speed of mold clamping force is faster, put on die device 19 grades load change more sharply.Therefore, reciprocal DC current I
1Intensity to consider production efficiency and put on this two aspect of change of the load of die device 19 grades, predetermine by test etc.And, reciprocal DC current I
1Intensity also can be according to producing predetermined mold clamping force P
0The time DC current I
0Intensity decide.
But, if make reciprocal DC current I
1The time of flowing is elongated, and electromagnet 49 can adsorb with adsorption section 51 again, and therefore, as shown in ruling with single-point in Fig. 4 (b), mold clamping force increases again.In addition, can infer that mold clamping force reverts to that again to increase before zero be because in electromagnet 49, residual magnetic field is uneven, and the timing that magnetic field disappears is different along with the difference of position.
Therefore, increase again in order to suppress mold clamping force, when removing mold clamping force, can judge whether (Pmin～Pmax) in preset range of mold clamping force by the mold clamping force detection unit 66 that control part 60 possesses.This judgement can repeat by each scheduled time based on carrying out as the detected value of the strain transducer 55 of mold clamping force sensor and/or the detected value (alternate position spike) of position sensor 53.
When mold clamping force detection unit 66 judged that mold clamping force is in preset range, matched moulds handling part 62 can be ended to the electric current supply of the coil 48 of electromagnet 49.Termination is supplied with the timing of electric currents to the coil 48 of electromagnet 49 can be in the way that mold clamping force increases again, but preferably in the way that mold clamping force descends.Due to the interior no current flows of coil 48 after ending to supply with electric current to the coil 48 of electromagnet 49, so mold clamping force is to descend with the corresponding speed of the operating lag of electromagnet 49.
Then, describe removing based on the mold clamping force of matched moulds handling part 62 variation of processing according to Fig. 5.Following processing is carried out after the mold clamping force that will be scheduled to puts on die device 19 and before die sinking.
The electric current that Fig. 5 (a) expression is supplied with to magnet spool over time, Fig. 5 (b) expression is based on the mold clamping force of electromagnet over time.
In variation shown in Figure 5, removing predetermined mold clamping force P
0The time, make the direct current strength of flow of the coil 48 that flows to electromagnet 49 from moment t
0Beginning reduces gradually, at moment t
11After becoming zero, the direction that changes DC current increases the direct current strength of flow gradually.So, make and produce predetermined mold clamping force P
0The DC current I of direction of opposite direction
11After flowing to the coil 48 of electromagnet 49, before die sinking, make the direction of the DC current of the coil 48 that flows to electromagnet 49 reverse more than 1 time.When counter-rotating, can set the maximum (I of DC current intensity littlely
11＞I
12＞I
13＞I
14＞I
15).Counter-rotating is (t regularly
12＜t
13＜t
14＜t
15) can be about to begin for the absorption again of electromagnet 49 and adsorption section 51 before, that is, and before mold clamping force is about to begin increase.
So, the counter-rotating of the direction of the DC current by making the coil 48 that flows to electromagnet 49 can reduce the impact of magnetic field inequality residual in electromagnet 49, and can further promote mold clamping force to descend, and can further enhance productivity.
And when long and mold clamping force increased again when the electric current supply time, the direction of DC current that can be by making the coil 48 that flows to electromagnet 49 reversed to make mold clamping force to descend once again.Therefore, the free degree that pattern is set is higher, controls lighter.
Above, one embodiment of the present invention etc. is illustrated, but the present invention is not limited to above-mentioned embodiment etc., in not departing from the scope of the present invention, can be to various distortion or the replacement in addition such as above-mentioned embodiment.
For example, in the example that represents with solid line in Fig. 4, at moment t
0Make the direction counter-rotating of the DC current of the coil 48 that flows to electromagnet 49, but also can be at moment t
0Temporarily stop to the electric current supply of electromagnet 49, after the scheduled time, with reciprocal DC current I
