The work of injection (mo(u)lding) machine 10 is controlled by controller 90.Controller 90 consists of CPU and memory etc., carries out the program being stored in memory etc. realize various functions by CPU.Controller 90 for example possesses the mould switching handling part 91 of controlling mould and opening and closing operation, the matched moulds handling part 92 of controlling matched moulds operation.
Then, the work of injection (mo(u)lding) machine 10 is described.
In mold closing operation, mould opens and closes handling part 91 and drives linear motor 28, makes to advance by dynamic pressure plate 12.Like this, as shown in Figure 1, dynamic model 16 is connected on cover half 15, and mold closing operation finishes.In the moment that mold closing finishes, between rear fender 13 and adsorption plate 22, between electromagnet 49 and adsorption section 51, form predetermined gap delta.In addition, the required power of mold closing is compared very little with mold clamping force.
After mold closing finishes, in matched moulds operation, matched moulds handling part 92 is controlled electric current supply portion 60, to electromagnet 49 energisings.Like this, by electric current mobile in the coil 48 at electromagnet 49, in the interior generation of coil 48 magnetic field, magnetic core 46 is magnetized, and magnetic field is reinforced.And, separating predetermined gap δ, between opposed electromagnet 49 and adsorption section 51, produce absorption affinity, this absorption affinity passes to via bar 39 can dynamic pressure plate 12, can dynamic pressure plate 12 and fixation clip 11 between produce mold clamping force.Mold clamping force is detected by mold clamping force sensor 55.Mold clamping force sensor 55 can be for for example detecting the strain transducer of the elongation (strain) of the connecting rod 14 corresponding with mold clamping force.In addition, mold clamping force sensor also can, for detecting the force cell that imposes on accordingly the load of bar 39 with mold clamping force, be not particularly limited.Cylinder 17 is pressed against on the die device 19 of matched moulds state (with reference to Fig. 1), the molten resin penetrating from cylinder 17 is filled into the die cavity space of die device 19.The molten resin being filled is cooled and solidifies and become products formed.
Afterwards, in die sinking operation, mould opens and closes handling part 91 and drives linear motor 28, makes to retreat by dynamic pressure plate 12.Dynamic model 16 retreats and carries out die sinking.After die sinking, not shown liftout attachment ejects products formed from dynamic model 16.
Yet, change die device 19, during the varied in thickness of die device 19, at mold closing, finish time be engraved in the gap delta variation forming between rear fender 13 and adsorption plate 22.
Therefore, injection (mo(u)lding) machine 10 for gap delta is made as to optimum value, possess according to the varied in thickness of die device 19 regulate can dynamic pressure plate 12 and adsorption plate 22 between the thick adjusting device 40 of mould of distance B.The thick adjusting device 40 of mould consists of with motor 43 etc. the nut 42 that is formed on screw thread 41 in the rearward end of bar 39, screw togather with screw thread 41, the thick adjusting of mould that makes nut 42 rotations.Nut 42 is rotated and is bearing in freely when installing plate 27(does not exist installing plate 27 is adsorption plate 22) upper, along fore-and-aft direction, move freely together with installing plate 27 or adsorption plate 22.By screw thread 41 and nut 42, form the motion converter portion that the thick adjusting of mould is transformed to the translatory movement of bar 39 with rotatablely moving of motor 43.

Die device 19 starts moulding after installing and finishing, and repeatedly carries out mold closing operation, matched moulds operation, filling work procedure, pressurize operation, refrigerating work procedure, die sinking operation, ejects the series of processes such as operation.
The controller 90 of present embodiment has the electromagnet hyperthermic treatment portion 96 that makes electromagnet 49 heat up before starting moulding.Electromagnet hyperthermic treatment portion 96 for example controls electric current supply portion 60, to electromagnet 49 energisings, produces Joule heat, and electromagnet 49 is heated up.Electromagnet hyperthermic treatment portion 96 can start the intensification of electromagnet 49 by the user instruction based on through input part 61 inputs.
Electromagnet hyperthermic treatment portion 96 can be by the temperature of not shown temperature sensor monitors electromagnet 49, and controls the energising of electromagnet 49, so that the temperature of electromagnet 49 becomes design temperature.For example, in the beginning that heats up, electromagnet hyperthermic treatment portion 96 is continuously to electromagnet 49 energisings, and when the temperature of electromagnet 49 approaches design temperature, electromagnet hyperthermic treatment portion 96 can be intermittently to electromagnet 49 energisings.The temperature of the thermal equilibrium state when design temperature of electromagnet 49 is set to moulding, waits and obtains by experiment.Temperature sensor is for example arranged on the inner side of the coil 48 of electromagnet 49.
Fig. 3 means the temperature inversion of electromagnet of one embodiment of the present invention and the figure of the timing of each operation.
As shown in Figure 3, electromagnet hyperthermic treatment portion 96, before moulding starts, to electromagnet 49 energisings, heats up electromagnet 49.The temperature stabilization of electromagnet 49, after injection (mo(u)lding) machine 10 in stable condition, starts moulding, so the stay in grade of products formed, the waste that can cut down moulding material.
And, as shown in Figure 3, before electromagnet hyperthermic treatment portion 96 can finish in the installation of die device 19, to electromagnet 49 energisings, electromagnet 49 is heated up.The temperature stabilization of electromagnet 49, after in stable conditionization of injection (mo(u)lding) machine 10, installation exercise finishes, and therefore by once mounting operation, just can make the posture optimization of die device 19.Even if make electromagnet 49 heat up before the installation of die device 19 starts, also can obtain same effect.
When electromagnet hyperthermic treatment portion 96 switches on to electromagnet 49 before moulding starts, the continuous conduction time of the electromagnet 49 in the time of can continuing than moulding (matched moulds operation institute's time spent), long Time Continuous ground switched on to electromagnet 49.The programming rate of electromagnet 49 accelerates, till the stand-by period of the temperature stabilization of electromagnet 49 shortens.In addition, as mentioned above, when the temperature of electromagnet 49 approaches design temperature, electromagnet hyperthermic treatment portion 96 can be intermittently to electromagnet 49 energisings.
During continuously to electromagnet 49 energising, mobile electric current more than can reversing once in the coil 48 of electromagnet 49.The magnetic polarity reversal of electromagnet 49, therefore, can suppress electromagnet 49 circumferential component (for example, die device 19, fixation clip 11, can dynamic pressure plate 12, connecting rod 14 etc.) magnetization.
And in electromagnet 49, the size of mobile electric current is large while switching on when when electromagnet hyperthermic treatment portion 96 works electricity by starting to advance in moulding, in electromagnet 49, the size of mobile electric current is set to such an extent that compare in moulding.The programming rate of electromagnet 49 accelerates, and the stand-by period till the temperature stabilization of electromagnet 49 shortens.
And electromagnet hyperthermic treatment portion 96 makes electromagnet 49 heat up while can the die device 19 before moulding starts heating up.Because heating process and other operation of electromagnet 49 are carried out simultaneously, therefore, the stand-by period till injection (mo(u)lding) machine 10 in stable condition further shortens.
As the heater of die device 19, use and to be embedded in the heater of die device 19, to the feedway etc. of supplying with the heat mediums such as warm water in the stream of die device 19.The heater of die device 19 is for example controlled by the mould hyperthermic treatment portion 98 of controller 90.
Mould hyperthermic treatment portion 98 can be based on via input part 61 input user's instruction start the intensification of die device 19.The intensification of die device 19 starts regularly can be for before moulding starts, also can for the installation exercise of die device 19 midway.
Any one party work in electromagnet hyperthermic treatment portion 96 and mould hyperthermic treatment portion 98 and while starting to heat up, the opposing party can automatic operation and start to heat up.And during any one party work, in order to arouse user's attention, display part 62 can show by user confirms the image whether the opposing party can work.By controller 90, control the demonstration of display part 62.While having seen the input that the user of the image of display part 62 is scheduled to by input part 61, the opposing party's work.
In addition, the input part 61 of present embodiment and display part are arranged for 62 minutes, still, for example also can be used as touch-screen and are wholely set.
For example, and electromagnet hyperthermic treatment portion 96 can, when the cylinder 17 of supplying with moulding material (resin particle) heats up before moulding starts, heat up electromagnet 49.The operation of the intensification of electromagnet 49 and other operations are carried out simultaneously, and therefore, the stand-by period till injection (mo(u)lding) machine 10 in stable condition further shortens.In addition, the intensification of electromagnet 49 can be carried out with the intensification of cylinder 17 and the intensification of die device 19 simultaneously.
The heating source of cylinder 17 (for example heater) is controlled by the cylinder hyperthermic treatment portion 99 of controller 90.
Cylinder hyperthermic treatment portion 99 can be based on via input part 61 input user's instruction, start the intensification of cylinder 17.The intensification zero hour of cylinder 17 is so long as before moulding starts, be not particularly limited.
Any one party work in electromagnet hyperthermic treatment portion 96 and cylinder hyperthermic treatment portion 99 and while starting to heat up, the opposing party can automatic operation and start to heat up.And during any one party work, in order to arouse user's attention, display part 62 can show by user confirms the image whether the opposing party works.The demonstration of display part 62 is controlled by controller 90.While having seen the input that the user of the image of expressed portion 62 is scheduled to by input part 61, the opposing party's work.
And the heater of the die device 19 of present embodiment is arranged on injection (mo(u)lding) machine, but also can be located on the periphery machine of injection (mo(u)lding) machine.The temperature of die device can be different by the controller from injection (mo(u)lding) machine other controllers control.
And controller 90 can have electromagnet intensification license portion 97, this electromagnet intensification license portion 97 monitors the state of injection (mo(u)lding) machine 10, and the state based on injection (mo(u)lding) machine 10, determines whether based on 96 pairs of electromagnet 49 of electromagnet hyperthermic treatment portion, switch on.Electromagnet intensification license portion 97, when the state of injection (mo(u)lding) machine 10 is not predetermined state, forbids the energising of electromagnet 49, permits the energising of electromagnet 49 when the state of injection (mo(u)lding) machine 10 is predetermined state.
For example, electromagnet intensification license portion 97 can be made as the distance between electromagnet 49 and adsorption section 22 L, the 1st threshold value is being made as to L1(L1 >=δ), 2nd threshold value larger than the 1st threshold value is made as to L2(L2 > L1) time, when L1 < L < L2, forbid, to electromagnet 49 energisings, when L≤L1 or L >=L2, permitting the energising of electromagnet 49.Distance L between electromagnet 49 and adsorption section 22 for example detects by position sensor 53.When distance L is the 1st threshold value L1 following (L≤L1), dynamic model 16 contacts with cover half 15 or devices spaced apart is opposed a little.Thus, DM 49 and absorption are during adsorption section 51, and likely adsorption plate 22 accelerates hardly, and mobile dynamic model 16, cover half 15 breakages together with adsorption plate 22.And when distance L is the 2nd threshold value L2 above (L >=L2), electromagnet 49 fully separates with adsorption section 22, even DM 49, the absorption affinity that acts on adsorption section 22 is also very little.Therefore, adsorption plate 22 moves hardly, does not have the possibility of dynamic model 16 and cover half 15 breakages.In addition, electromagnet intensification license portion 97 can monitor whether the state of injection (mo(u)lding) machine 10 is mold closing done state, forbids the energising of electromagnet 49 when not for mold closing done state, permits the energising of electromagnet 49 when mold closing done state.
And electromagnet intensification license portion 97 can, based on whether produce mold clamping force when electromagnet 49 is supplied with weak current, permit or forbid the intensification of the electromagnet 49 based on electromagnet hyperthermic treatment portion 96.For example, when electromagnet intensification license portion 97 produces mold clamping force by supplying with weak current, judgement mold closing finishes, the intensification of license electromagnet 49.And electromagnet intensification license portion 97 is not when producing mold clamping force by supplying with weak current, being judged as mold closing does not finish, and forbids the intensification of electromagnet 49.The current value when electromagnet 49 of the current value ratio of weak current based on electromagnet hyperthermic treatment portion 96 heats up is little.When judging whether to produce mold clamping force, use the detected value of mold clamping force sensor 57.
Above, injection molding machine embodiment is illustrated, but the present invention is not limited to above-mentioned embodiment, in the scope that can record in technical scheme, carries out various distortion and improvement.
For example, the electromagnet hyperthermic treatment portion 96 of above-mentioned embodiment to electromagnet 49 energisings, still also can drive the heater of the rear fender 13 that is formed with electromagnet 49 for electromagnet 49 is heated up.As the heater of rear fender 13, use to the stream of rear fender 13 supply with the heat mediums such as warm water feedway, be embedded in the heater of rear fender 13 etc.
And the intensification of the electromagnet 49 of above-mentioned embodiment is carried out when the exchange of die device 19, but as long as before moulding starts, in die device 19 exchanges in addition, carry out also passable.For example, once in interruption moulding such as nights, electromagnet 49 can not generate heat, and the temperature of electromagnet 49 declines, and therefore, also can before starting moulding again, carry out the intensification of electromagnet 49 afterwards.
And, after also can finishing in the intensification of electromagnet 49 temperature stabilization of electromagnet 49 state under carry out the thick adjusting of mould.The gap delta regulating by the thick adjusting of mould is stable, and mold clamping force during moulding is stable.Same reason, the thick adjusting of mould is carried out after also can finishing in the intensification of die device 19.
