Injection (mo(u)lding) machine 10 is carried out: close the mold closing operation of die device 30, fastening die device 30
Matched moulds operation, control the injection process of the injection speed of resin, control the guarantor of injection pressure of resin
Pressure operation, make in die device 30 after pressurize operation refrigerating work procedure that resin solidify, measure for
The measurement process of the resin of next products formed, open the die sinking operation of die device 30 and from die sinking
After die device 30 release operation that products formed is released.Injection (mo(u)lding) machine is by being repeated these
Operation, manufactures products formed repeatedly.Fig. 3 represent injection process, pressurize operation, refrigerating work procedure and
The time change of the various parameters of measurement process.
Injection process is carried out after matched moulds operation.In injection process, drive injection motor 43, make spiral shell
Bar 52 advances.Screw rod 52 pushes molten resin and injects from nozzle 41.Molten resin is via being formed at
Running channel S, runner R, cast gate G etc. in die device 30 are flowed in cavity space C.
In injection process, in order to make the pace of screw rod 52 become setting value, electric current is supplied to note
Penetrate with motor 43.The setting value of screw speed changes with the advancement stage of screw position.Position is examined
When the detected value of survey device 57 reaches setting value, the setting value change of screw speed.
It addition, the change of the setting value of screw speed replaces position detector 57, use measurement away from note
The timer penetrating the time that operation starts (moment t0) can also.Screw position has corresponding with the time
Relation, therefore based on which change screw speed setting value all as.
The setting value of screw speed moment t1 substantially 0(zero before pressurize operation starts).Screw rod
52 slow down rapidly, stop at moment t2 screw rod 52.When screw rod 52 stops, screw position is sent out hardly
Changing, therefore, replaces control portion 80 to monitor the detected value of position detector 57, by timer
The elapsed time of the setting start time t1 that range finding screw rod stops.
Here, " screw rod stopping " course referring to the state that screw rod 52 stops completely, and additionally screw rod 52 is micro-
State, the state of screw rod 52 dead slow astern that speed is advanced are also included within interior.During screw rod 52 dead slow astern,
The front screw 52 of dead slow astern temporarily ceases.
When moment t2 screw rod 52 stops, the flow front of resin will not arrive the end of cavity space C
End.During screw rod 52 stops, the flow front of resin is applied to the work of the compression stress of resin in injection
Use lower advance.Owing to screw rod 52 stops, therefore, because flow resistance resin slows down gradually.
From injection process, the switching to pressurize operation is referred to as V/P switching.V/P switches in and stops away from screw rod
The time of setting start time t1 only reaches the moment t3 of setting value and carries out.
If cooling down resin, then resin thermal contraction in cavity space C.Tree for supplemental heat amount of contraction
Fat, in pressurize operation, keeps the resin pressure (injection pressure of resin) being applied to screw rod 52
For predetermined pressure.In order to make the detected value of resin pressure detector 50 become setting value, to injection
Motor 43 supplies electric current.The setting value of the resin injection pressure of pressurize operation can in time through rank
The ground change of section property.In pressurize operation, owing to the change of screw position is little, therefore, with control portion 80
