Electro/mechanical mould protection

ALLROUNDER 221 K machines are standardly equippedwith an electro-mechanical mould protection. This mouldprotection serves the purpose of preventing damage to themould if foreign particles or injected parts get between themould halves during closing. When the mould protectionreacts the controller interrupts the clamping process andissues an alarm.

The sprung mould protection platen with end switch S104is located on the fixed clamping platen. When the mouldcloses, the programmable stroke marking S119 must firstbe reached before the sprung mould protection platen ispressed against the fixed clamping platen herebyactivating switch S104.

If there is a foreign particle between the mould halves themould protection plate is pressed against the fixedclamping platen and activates switch S104 before thestroke marking for the mould protection is reached. For anillustration of this, please see the following diagrams.

Page 77: Arburg 221 Manual

73

programmed stroke marking is reached before switchS104 is activated, → cycle continues.

Foreign particle (7) causes switch S104 to be activatedbefore position marking s119 is reached → alarm.

( GR1432ZA GS1432ZA )

Page 78: Arburg 221 Manual

74

The minimum spring resistance for the mould protectionplaten is approx. 2 kN.

With stiffly moving cheek moulds the spring resistance ofapprox. 2kN could be too low which means the mouldprotecion might react without there being any foreignparticle between the mould halves. For such casesstronger compression springs are available for the mouldprotection platen.

s119 Mould protection offAs soon as the stroke position s119 is reached, themould protection is switched off. The switch S104is no longer monitored.

f105 2nd start attempt after t105 ¹.Effect: When the mould protection has reactedduring mould closing, the controller does not issuean alarm immediately. The machine opens themould and activates the ejector. It then tries toclose the mould again. Only when this 2nd attemptis unsuccessful, does the controller issue an alarm.

f102 Immediate machine stop.When “yes” is input the machine stops immediately afterthe mould protection has reacted.

¹ not standard

Page 79: Arburg 221 Manual

75

Hydraulic mould protection ¹

Instead of the electro-mechanical mould protection withsprung mould protection platen there is the option of ahydraulic mould protection. With the hydraulic mouldprotection the otherwise sprung mould protection platen isfirmly attached to the fixed clamping platen.

On closing, the mould must move the last centimeterswithin a certain time with low force. This distance is calledthe mould protection stroke. If foreign bodis or injectedparts left in the mould prevent the mould from closingunhindered, the time programmed for the completion ofthe mould protection stroke is exceeded. The controllerinterrupts the closing process and issues an alarm.Themould then re-opens and normally remains undamaged.

¹ not standard

Page 80: Arburg 221 Manual

76

s104 The controller switches from closing force toprotection force (F104) as soon as the mouldreaches s104. s104 is the starting point of themould protection stroke. The measurement ofmould protection time t4052 starts from this point.

s105 Clamping force onThe controller switches from protection force toclamping force as soon as s105 is reached. s105 isthe end point of the mould protection stroke. Themeasurement of mould protection time t4052 endsat this point.

F104 Protection forceF104 determines the force with which the mouldmoves through the mould protection stroke (s104to s105). F104 should be as low as possible. Thecontroller switches from closing force to protectionforce F104 as soon as the mould has reachedposition s103.

t105 Mould protectionEffect: The mould must complete the mouldprotection stroke (s104 to s105) within t105. If t105is exceeded the controller issues an alarm.

t4052 Measured timeThe time that the mould actually takes to completethe mould protection stroke is measured anddisplayed at t4052.

6. Zeroing the stroke measuring systems

The stroke measuring systems of the machine always startthe measurement from fixed zero points which you cannotalter (machine related zero points). You can however inputall data for the movement sequences in absolute values.To make this possible each mould must have its own zeropoints for the stroke measuring system. These aredetermined in a simple way by “zeroing” the strokemeasuring system.

The following stroke measuring systems must bezeroed:

u Ejector movementsZero point = ejector retracted

u Nozzle movementsZero point = nozzle at mould

I M P O R T A N T

Contrary to ALLROUNDER machines with fully hydraulicclamping unit, the moulds of the ALLROUNDER 221 Kversions with toggle system are not zeroed.The zero point is automatically the locking (or extended)position of the toggle.
