2.6.2.1 Injection Molding Machine Output Signals
Plug Contact No.
Function
1
,
9
Emergency stop of machine
The emergency stop switch of the injection molding machine is used to interrupt the
emergence stop circuit of the robot.
2
Mold open
The switch contact (pin contact 16) is closed when mould opening position is equal or
more than required position. Inadvertent alteration to mould opening stroke smaller
than that required for the handing device to approach must be impossible.
3
,
11
Safety system active
The switch contact is closed when safety devices (e.g. safety guard, footboard safety,
etc.) on the injection molding machine are operative so that dangerous movements of
the handing device/robot are possible. The signal is active in any operation mode.
4
Ejector back
The switch contact is closed when the ejector has been retracted regardless of the
moving platen position. (See pin contact No.16) acknowledgement f or the
“
Enable
ejector back
”
signal (see pin contact No 21), when the ejector sequence is selected.
(see pin contact No.16)
5
Ejector forward
The switch contact (see pin contact No.16) is closed when the ejector has been
advanced. The signal is the acknowledgement signal for the
“
enable ejector forward
”
(see pin contact No 22).
It is recommended to close the switch contact when the ejector sequence not in use.
(see pin contact No.16)
6
Optional
Core pullers free for robot to travel in
Switch (see pin contact No.16) is closed when the core pullers, regardless of the
position of the movable tool plate, are in position for free travel
–
in of the robot.
7
Optional
Core pullers in position for removal of injection moldings
Switch (pin contact No.16) is closed when the core pullers are in position for removal of
the injection molding.
8
Optional
Reject
Switch (see pin contact No.16) is closed when the molded piece is a reject. the switch
must be closed when the tool is open and must remain closed at least until
“
enable
mould close
”
(see pin contact No.17)
10
Fully automatic mode injection molding machine
Switch (see pin contact No.16) is closed when the operating mode selector switch is on
“
semi-automatic
”
or
“
fully automatic mode
”
.
12
Mold closed
Switch (see pin contact No.16) is closed when the mould closing has been completed,
the signal
“
enable close
”
is no longer necessary. (see pin contact No.17)
13 Optional
Free
14
Optional
Mold at intermediate position
Switch (see pin contact No.16) is closed when the IMM has reached the specified
intermediate position and remains closed until the IMM is completely open .the signal
may be used in two ways:
1) Mould opening stops on intermediate position and gives start signal to handling
device/robot. mould opening restarts with the signal
”
Enable full mould opening
”
(see
contact No.28)
2) Mould opening doesn
’
t stop on intermediate position, however gives the signal to
handling device/robot. (see pin contact No.16)
The switch contact is open when intermediate mould opening position is not in use.
15 Optional
