4.2 Mold Setting
This is to set up open/close mold, mold adjust, slope, etc.
【Open/close mold】
This page is for open/close mold setting.
LNC Toggle Controller
PAGE FUNCTIONS
The settings in this page include:
Depending on the type of mold, the procedure for mold close is: high velocity low
velocity low pressure high pressure mold clamping. The other situation could also be
high velocity 1 low velocity 1 high velocity 2 low velocity 2 low pressure high
pressure mold clamping; the steps are usually applied for tri-plate molds. At high-velocity
mold close phase, the fully-open molds close at high velocity towards each other, and then
enter low-velocity cushion phase. When the distance between closing molds is the same
as the height of finished products, the phase turns to low-pressure mold protection. Finally,
when male and female molds contact each other, the phase turns from low-pressure mold
protection to high-pressure mold clamping.
Purposes for low-pressure mold protection：
1. If some finished product does not detach completely from the molding area and is not
detected, molds will be damaged during mold close operation.
2. If the operator enters the mold clamping area by accident during operation while the
machine is still running, low-pressure mold protection will protect the operator from
getting hurt, or will help reduce the damage or loss.
LNC Technology Co., Ltd.
LNC-Toggle Controller
PAGE FUNCTIONS
Mold Close Pressure：Set mold close pressure of each phase. For high & low
velocity mold close phases, set pressure as much as necessary to activate mold to
motion. For low-pressure mold close operation, set pressure to low for mold
protection. For high-pressure clamp operation, set only the required clamp
pressure as excess pressure would cause overload of mechanical structure and
also cause waste of energy.
Mold Close Velocity：Set mold close velocity for each phase. If a tri-plate mold is
used, 2-phase high and low velocity can be applied.
Mold Close Position：Set mold close ending position at each phase. Depending on
the type of a mold, set a proper position to switch to the next mold close phase.
The procedure of Mold open is pressure release low velocity mold open
high velocity mold open medium velocity mold open cushion. First, high
pressure caused by clamping operation is released. Then, mold is open at low
velocity, and a molding part is separated from the female mold at low-velocity
phase. To prevent parts from damage, mold open velocity should be low. After a
part is detached from female mold, male mold is opened at a higher velocity to
the distance sufficient for ejection, and then travels at medium velocity and then
enters cushion phase until it fully stops.
If a robot is applied to clamp the molding part, please pay attention to the
distance for the mold to travel from medium velocity phase to cushion phase. If
the distance is set too short, male mode might not be able to stop stably due to
mechanical inertia and hence makes strong impact on the machine.
Release Time：Set pressure-releasing time at early phase of mold open. If the set
value is too small, damage might occur during mold open.
Mold Open Pressure：Set mold open pressure at each phase. For low velocity
phase, as the purpose is to separate the molding part from the mold, the required
pressure could be more. For the other phases, pressure should be set as much as
necessary to activate the mold to motion.
Mold Open Velocity：Set the mold open velocity for each phase. To prevent impact
due to high velocity at cushion phase, medium velocity for mold open should not be
too high.
Mold Open Position：Set switch position of mold open for each phase according to
the type of a mold.

【Open mold release pressure setting】
Mold open procedure is Pressure release Low speed High speed Medium speed
reduce speedcushion.
The function of pressure release is to prevent serious vibration of the machine caused by
sudden release of mold close pressure during mold open. Mold open pressure release
mode is a little bit different according to different forms of mold clamping.
For general hydraulic systems, mold open back pressure valve is opened to reduce
mechanical vibration during pressure release.

PAGE FUNCTIONS
【Ejector/Blow】
This page provides the following settings：
There are two kinds of ejection forward operation: low velocity & high velocity. Low velocity
ejection is applied when the molding part is ejected apart from the male mold because high
velocity might damage the molding part. After the molding part is detached from male mold,
use either a robot to pick up the molding part or simply eject the molding part to finished
product ejected area.
Eject Forward Pressure：Set the ejection pressure of each phase. At low
velocity ejection phase, the system should provide enough pressure to
overcome adhesive force and friction between the molding part and the mold.
For high velocity ejection, pressure should be set according to the design of
each mold.
Eject Forward Velocity：Set ejection velocity of each phase. The primary
concern for low velocity injection setting is not to damage the molding part.
Eject Forward Position：Set ejection ending position at each phase. Low velocity
ejection position should provide at least the space for a molding part to detach
from the mold so the molding part can be ejected later at a higher velocity until it
can be completely picked up.
Eject Forward Delay：Set the delay time to begin ejection after mold open
operation is finished.
Eject Counter：Set ejection number at each phase for each ejection model.

PAGE FUNCTIONS
Eject Backward Pressure：Set ejection backward pressure at each phase.
Eject Backward Velocity：Set ejection backward velocity at each phase.
Eject Backward Position：Set ejection backward ending position at each phase.
Eject Backward Delay：Set delay time between the completion of ejection and
the next eject backward operation.
Eject Model：The settings of ejection modes include
0 Not applied: Ejector is not applied.
1 Single ejection: Ejection is completed by the operation of one ejecting forward
and one ejecting backward operation.
2 Continuous ejection: Eject forward/backward speed is decided by ejection
times. When the set time is reached, the ejection program is finished.
3 Vibration ejection: After the first ejection is finished (including low-velocity &
high-velocity ejection advance), ejection is repeated according to the
vibration stroke & ejection times in the vibration program until the set ejection
time is reached, and then ejector moves backward (including low-velocity &
high-velocity ejection backward) to finish the ejection program.
4 Stop after ejection: After finishing ejecting forward according to the set speed
and pressure setting of advance ejection, ejector stops at the farthest point
and then ready to eject backward when the next cycle starts. This option is
most suitable when a robot is applied to pick up the finished product.
5 Stop after vibration: After vibration is finished according to the set vibration
stroke and ejecting forward time, ejector stops at the farthest point and then
starts to eject backward when the next cycle starts. This option is most
suitable when a robot is applied to retrieve the finished product.
Single Model Stay Time：When the ejection model is set to single ejection, this
option sets the stay time which starts counting from ejecting forward is stop at
set position. When the duration of the set time is reached, ejector starts to eject
backward.
Blow Model：Blow model types are listed as below:
0 Not applied: Blowing function is not applied.
1 During mold open: Air blow valve is switched on when the mold is open to the
designated position.
2 After mold close: Air blow valve is switched on when mold is open to the
ending position.
3 During charging: Air blow valve is switched on during plastic charging after
injection is completed.

Reason: Incorrect setting of Ejector backward parameter.
Solutions: 1. This warning does not show often. In case of warning happens, it could be
caused by related procedure.
2. Please contact our personnel concerned or the machine supplier.
Note: When it comes to “exceeds the limits of set values ”, it means that the temperature
may higher than the upper limit of set values, or lower than the lower limit of set values.
Reason: Temperature checks are proceeded automatically before all screw actions
(Injection, Suckback, Feeding..). Possible causes are as follows:
1. (Cold start monitoring function) is turned ON, while "the temperature has not yet
reached the set value at the first cold start."
2. Item 1 is satisfied, but it is not yet the (Cold start delay time).
3. Temperature goes beyond the upper or lower limit of safe set values.
Solutions: 1. While turning on (Cold start monitoring function) (Parameter R (32131 ~
32137, temperature control section x, Cold start temperature monitoring
function switch)), make sure that all sections had reach the target
temperatures.
2. When the alarm is activated, check the temperatures of all sections. Upper and
lower limits (parameter R (32024 ~ 32030) of over-high temperature alarm, or
parameter R (32036 ~ 32042) of over-low temperature alarm) of all sections’
target temperatures are adjustable.
3. Adjust appropriate cold start delay time (parameter R (32052))
Reason: The alarm will be triggered when temperature control sections do not match
those of hardware. For instance, alarm will be triggered as temperature control sections
are set to 1, 2, and 3, while those of thermocouple are only connected to 1 and 2.
Solutions: 1. Make sure that temperature control sections match those of hardware.
(Parameter R (32056), temperature control sections used.)
2. Standby temperature control sections must be short-circuited.
