Injection (mo(u)lding) machine 10 possesses as making screw rod 13 at the measure motor 41 of the drive source of cylinder body 11 interior rotations.The rotation of measure motor 41 is delivered to ejaculation axle 43 and makes screw rod 13 rotations via the connecting members such as conveyer belt or belt wheel 42.In addition, measure motor 41 also can be direct drive motor, and for example the output shaft of measure motor 41 also can coaxially link with ejaculation axle 43.
Injection (mo(u)lding) machine 10 possesses as making screw rod 13 injection motor 51 of mobile drive source vertically in cylinder body 11.The rotation of injection motor 51 is delivered to ballscrew shaft 52.The ball-screw nut 53 that carries out forward-reverse by the rotation of ballscrew shaft 52 is fixed on pressure plare 54.Pressure plare 54 can move along the guide rod 55,56 that is fixed on base (not shown).The forward-reverse motion of pressure plare 54 for example, is delivered to screw rod 13 via pressure detector (force cell) 57, bearing 58, ejaculation axle 43 and makes screw rod 13 advance and retreat.The position of screw rod 13 is detected with the position detector 59 that is installed on pressure plare 54.
The action of injection (mo(u)lding) machine 10 is controlled by controller 60.Controller 60 comprises storage part 64, input interface, output interface, timer and the counters etc. such as the read-write RAM63, hard disk of CPU61, the ROM62 that control program etc. is stored, storage operation result.Controller 60 is stored in ROM62 or storage part 64 program by being carried out by CPU61 realizes various functions.
Then, the action of injection (mo(u)lding) machine 10 is described.
Injection (mo(u)lding) machine 10 carries out following operation, the matched moulds operation of the mold closing operation of closing molding device, fastening die device, makes resin curing refrigerating work procedure, the measurement process that the molten resin for next products formed is measured, the die sinking operation of opening die device and die device from die sinking in die device release the release operation of products formed after molten resin is poured into the filling work procedure in die device, the pressurize operation that poured into a mould resin is exerted pressure, pressurize operation.Injection (mo(u)lding) machine 10 is manufactured products formed repeatedly by repeatedly carrying out these operations.In order to shorten molding cycle, measurement process can carry out during refrigerating work procedure.
In measurement process, controller 60 drives measure motor 41 to make screw rod 13 rotations.The rotating speed of screw rod 13 detects by the encoder 41a that the rotating speed of measure motor 41 is detected, and testing result is supplied to controller 60.60 pairs of electric currents that are supplied to measure motor 41 of controller are controlled, so that the rotating speed of screw rod 13 becomes setting rotating speed.Now, the electric current (torque of measure motor 41) that 46 pairs of controller 60 use current sensors are supplied to measure motor 41 monitors.
If drive measure motor 41 to make screw rod 13 rotations, the scraper plate of screw rod 13 (ridge) 15 moves, and the resin particle being supplied in the thread groove of screw rod 13 is forwards carried.When resin is forwards mobile in cylinder body 11, by the heating such as heat from cylinder body 11, at the leading section of cylinder body 11, become the state of complete melting.Screw rod 13 retreats along with the place ahead savings molten resin at screw rod 13.
Screw rod 13 retreat during, controller 60 drives injection motors 51 to apply back pressure to screw rod 13.The back pressure of screw rod 13 detects with pressure detector 57, and testing result is supplied to controller 60.60 pairs of controllers are supplied to the electric current of injection motor 51 and control, so that the back pressure of screw rod 13 reaches setting back pressure.
Screw rod 13 retreat during, controller 60 use position detectors 59 monitor the position of screw rods 13.If screw rod 13 retreats into metering end position, at the place ahead of screw rod 13 savings, there is the resin of scheduled volume, controller 60 makes the driving of measure motor 41 stop the rotation of screw rod 13.
After measurement process, controller 60 also can make screw rod 13 not rotate and the back suction operation that retreats.In back suction operation, controller 60 drives injection motor 51, so that the astern speed of screw rod 13 reaches setting speed.If screw rod 13 retreats into resorption end position, controller 60 stops injecting the driving of motor 51.
In filling work procedure, 60 pairs of injection motors 51 of controller drive to make screw rod 13 to advance, and in the die cavity space in the die device of matched moulds state, are pressed into molten resin.The pace of screw rod 13 (issuing velocity of resin) detects with position detector 59, and testing result is supplied to controller 60.In addition, the pace of screw rod 13 also can detect by enough encoder 51a that the rotating speed of injection motor 51 is detected.60 pairs of controllers are supplied to the electric current of injection motor 51 and control, so that the pace of screw rod 13 reaches setting speed.The setting speed of screw rod 13 can change gradually according to screw position.Controller 60 monitors the position of screw rod 13 during filling work procedure with position detector 59.When the position of screw rod 13 reaches V/P switching position, controller 60 starts to carry out pressurize operation.In addition, also can reach V/P during switching time in the elapsed time from starting filling, controller 60 starts to carry out pressurize operation.
In pressurize operation, controller 60 use pressure detectors 57 detect the pressure that puts on screw rod 13, and injection motor 51 is driven, so that the injection pressure of resin reaches setting pressure.
But in the stabilisation of the quality of products formed, the stabilisation storing in measurement process in the temperature of the molten resin in the place ahead of screw rod 13 is important, and to reduce the shearing heat that the action by screw rod 13 likely produces in resin be also important as far as possible.Shearing heat is wayward, therefore becomes the reason of infringement stability.Shearing heat mainly produces at the compression unit 13b that the resin of screw rod 13 is compressed.The temperature of the resin in compression unit 13b is lower, and the resin in compression unit 13b is harder, and the torque of measure motor 41 uprises, shears heat to be increased.
Shearing heat is subject to the impact of following factor, the i.e. combination of the setting rotating speed of the design temperature of cylinder body 11, screw rod 13 and the setting back pressure of screw rod 13.Cylinder body 11(is region Z especially 1, Z 2) design temperature become lower, the temperature that is supplied to the resin of compression unit 13b more becomes low temperature, shearing heat more increases.And the setting rotating speed of screw rod 13 is higher, the resin that is supplied to compression unit 13b in time per unit more increases, more step-down, shearing heat more increase resin temperature.And the setting back pressure of screw rod 13 is higher, the resin increase, resin temperature step-down, the shearing heat that in the average unit interval, are supplied to compression unit 13b increase.Therefore, the combined effect of the setting rotating speed of the design temperature of cylinder body 11, screw rod 13 and the setting back pressure of screw rod 13 is sheared heat.
In present embodiment, controller 60 plays a role as supporting the set supporting portion that the back pressure of cylinder body 11 temperature, screw rod 13 rotating speeds and screw rod 13 is set.In addition, set supporting portion also can with to heating source H 1～H 4, measure motor 41 and the controller controlled of injection motor 51 be arranged for 60 minutes.
Controller 60 has storage part 64, described storage part by the combination of the setting back pressure of the setting rotating speed of the design temperature of cylinder body 11, screw rod 13 and screw rod 13 (following, referred to as " 3 setting values ") with for the evaluation of estimate that this combination is evaluated, set up corresponding storage.The combination of 3 setting values and evaluation of estimate also can for example be stored in storage part 64 with sheet form.In addition, the stores location of evaluation of estimate etc. is not particularly limited.ROM62 or RAM63 also can be used as the storage part 64 that the data such as evaluation of estimate are stored.
The design temperature that is stored in the cylinder body 11 of storage part 64 can be a plurality of region Z 1～Z 4middle All Ranges Z 1～Z 4design temperature, also can be regional area (region Z for example 1, Z 2) design temperature.The design temperature in the region of set supporting object also can be stored in storage part 64.
The evaluation of estimate that is stored in storage part 64 can be the value that represents to shear heat, also can be the variable quantity of the torque of the measure motor 41 in scheduled time in measurement process for example.
Fig. 2 means the figure of actual value of the torque (metering torque) of the measure motor based on one embodiment of the present invention.Fig. 3 means the figure of the actual value of the screw back pressure based on one embodiment of the present invention.In Fig. 2 and Fig. 3, transverse axis represents elapsed time from starting measurement process.
As shown in Figure 2, the torque of measure motor 41 is sharply risen after starting measurement process, afterwards, is tending towards rising.The torque of measure motor 41 is calculated according to the testing result of current sensor 46.
And as shown in Figure 3, the back pressure of screw rod 13 rises when starting measurement process, is held in afterwards setting back pressure.
Variable quantity (for example ascending amount) the Δ T of the torque of the measure motor 41 during the present inventor scheduled time Δ t measurement process from experimental result discovery is larger, and shearing heat easily increases, the stability of infringement products formed quality.Therefore, variation delta T is sheared to the value of heat as expression.
After the mensuration t1 zero hour of variation delta T also can reach in the back pressure of screw rod 13 moment t2 that sets back pressure.Can get rid of the impact of the back pressure change of screw rod 13.
