Stop.
The control circuit of injection moulding machine provided in an embodiment of the present invention, by being provided for exporting various switch control letters
Number control panel, and the starting switch and emergency stop switch being connected with control panel, it is ensured that the stability of switch controlling signal, greatly
The tune machine difficulty of old-fashioned injection moulding machine is reduced greatly.
Brief description of the drawings
By reading the detailed description made to non-limiting example made with reference to the following drawings, of the invention is other
Feature, objects and advantages will become more apparent upon：
Fig. 1 is the structure chart of the control circuit for the injection moulding machine that first embodiment of the invention is provided.
Embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that, in order to just
Part related to the present invention rather than entire infrastructure are illustrate only in description, accompanying drawing.
Present embodiments provide a kind of technical scheme of the control circuit of injection moulding machine.Referring to Fig. 1, injection moulding machine
Control circuit include control panel 1, starting switch 2, emergency stop switch 3, two temperature controllers 4,5, with two temperature controls
Upper section temperature switch 6 and lower section temperature switch 7, a transformer 8 that device is connected respectively, and an alternating current filter 9.
The function of control panel 1 is the control parameter by being got on the keypad by being arranged on shell, and output is each
Plant switch controlling signal.These switch controlling signals include：Direct current input, direct current output, exchange output, automatic start, charging
Completion, matched moulds completion, matched moulds high pressure, matched moulds low pressure, die sinking, alarm.
Control panel 1 provides two-way alternating current output signal, and respectively amplitude is 9V alternating current output signal, and amplitude is
24V alternating current output signal.Also, above-mentioned two-way alternating current output signal passes through the transformation of transformer 8, and alternating current filter 9
Ac filter after, be output to each corresponding signaling point, power supply provided for all parts.
Typically, above-mentioned AC signal is connected to starting switch 2 and emergency stop switch 3 after transformation and filtering.Open
Dynamic switch 2 is provided to user, and the startup of the motor of injection moulding machine is controlled for user.Emergency stop switch 3 is supplied to use again
Family, the jerk for the motor to injection moulding machine is controlled.
In addition, above-mentioned control circuit also includes：Upper section temperature switch 6, lower section temperature switch 7, and respectively with above-mentioned two
Two temperature controllers 4,5 of person's connection.Temperature controller 4,5 can gather the temperature of melt plastic cement in real time, and according to set in advance each
Individual temperature nodes parameter determines when to perform injection, when performs the specifically operation such as matched moulds.
The control that temperature controller 4,5 is performed for specific operation is realized by its temperature control signals exported.
In the present embodiment, temperature control signals include：Upper section temperature control signals and lower section temperature control signals.Upper section temperature control
Signal is used for controlling saving the die closing operation of part on mould, and lower section temperature control signals are used for controlling saving the conjunction of part under mould
Modulo operation.
Further, above-mentioned control circuit also includes several indicator lamps, also known as display lamp.Specifically, these indicator lamps
Have：Motor starting indicator lamp, power supply indicator, and jerk indicator lamp.Above-mentioned indicator lamp is connected with corresponding control signal, point
It is not used to refer to whether present motor has been started up, whether power supply has turned on, and whether motor is in jerk state.
In use, power switch is first turned on, Display panel screen is bright, and machine is started to warm up, by motor after temperature is arrived
Start, now machine just can normal work for revolution (emergency can press emergency stop switch).First set during work on panel
Put after corresponding parameter, while pressing two starting switches, machine matched moulds is simultaneously automatically performed a series of actions, then die sinking etc.
Treat to start next time.
Above-mentioned control circuit replaces original control circuit when carrying out tune machine to old-fashioned injection moulding machine.Due to replacing
The signal stabilization of control circuit afterwards, is not in the situation of signal ambiguity, therefore, it is possible to significantly overcome control circuit unstable,
