Embodiment
Technical scheme is described in further detail with reference to specific embodiment.
The PLC touch-screen control methods of spraying in a kind of mould of the present invention, including：
（1）Manual test pattern, as shown in Figure 2：By touch-screen click on manually blow, Y0 output points obtain signal coil obtain it is electric
Air valve, which is opened, blows；Manual water-jetting is clicked on by touch-screen, Y1 output points obtain signal coil and obtain electric water valve opening water spray；It is if same
When click on, then can reach the effect of atomizing spraying.To staff, signal detection can be carried out by this function, can be manually
Force the transmission signal to carry out failure judgement and check whether the break-make of signal and magnetic valve are normal.
（2）Automatic operation mode, as shown in Figure 3：By set on the touchscreen delay spray time, water spraying time,
Gassing time, under automatic mode, when PLC receives the thimble signal that die casting machine transmits, it is delayed after certain time, water valve is gentle
Valve is obtained electric while worked, and reaches atomizing effect.Spray is finished after beam, and water valve is closed, air valve works independently and continues to blow, and blows away mould
Surface moisture, circulation terminate, and then wait the thimble signal of subsequent cycle.
Further illustrated for automatic operation mode with one embodiment：
Under automatic operation mode, it is 50ms by setting delay spray time on the touchscreen, water spraying time 100ms, blows
The gas time is 200ms.Under automatic mode, when PLC receives the thimble signal that die casting machine transmits, be delayed 50ms after, water valve and
Air valve is obtained electric while worked, and reaches atomizing effect.100ms has been sprayed to terminate rear water valve and close air valve and work independently to continue to blow
100ms, die surface moisture is blown away, circulation terminates, and then waits the thimble signal of subsequent cycle.
As shown in figure 4, spraying control system cabinet device structure, including power supply 1, relay 2, PLC 3, display touch
Touch screen 4, scram button 5, power supply indicator 6 and contact terminal 7.The thimble signal that die casting machine is sent is connected to defeated by contact terminal
Enter relay, the input of PLC be connected to by the conversion of input relay, PLC by data wire with
Touch-screen real-time data communication is shown, PLC reads and writes rapidly judgement by the internal processes write again, from PLC
Signal is connected to output relay by output end, then is connected to contact electronics for connecing Y1 water valves, Y0 air valves from output relay
Signal wire connection.During such as failure, scram button can be pressed, system stops all work.
As shown in figure 1, show manual/auto switching push button, automatic testing button on the display touch-screen, blow manually
Gas button, manual water outlet button, delay spraying button, water spraying time button, gassing time button, setting time button, display
Time button, time setting button, extrusion call button, air valve call button and water valve call button.
Spray it is not in place, the time grasp it is unreasonable be one of the main reasons.Interior spraying has plenty of using magnetic valve to control
The gentle break-make of water, change the aperture of valve using control button so as to carrying out the length of control time.As for signaling point system of selection
Also differ, have using spraying robot ' switch board internal signal point come send open aqueous vapor solenoid signal, or directly from
Die casting switch board PLC directly chooses signaling point.In a word, method is cumbersome, installation inconvenience, waste of materials, electromagnetism can also often occurs
Valve damage finds that failure is difficult not in time and excludes, the problems such as bit loss bad accessory costliness is put on I/O plates.
Using spraying integrated control system in the set, so that it may according to actual control need that the length of time is adjusted flexibly, enter
And reach accurate control time parameter purpose.For the set system compared with other method of works, a prominent advantage is exactly will be auxiliary
The signaling point that helping equipment needs spins off, and is controlled using single 24v power supplys and touch screen/PLC, ensure that to the full extent
The safety of component, circuit in die casting machine switch board.Required signal is input to output by contact terminal and does visualizing mark
Label, save installation equipment and connect the cumbersome puzzlement of auxiliary signal line, it is simple and convenient, it is very clear.The system is writing program
Shi Te adds one of defence program, by setting die casting machine work modulus to be counted, once reach setting（Such as 1000
Mould）, then PLC can enter lock-out state, so that alert device employee need to carry out the operation such as maintenance to equipment.
Present invention reliable and durable in system, mistake proofing performance is good, while simple to operate, convenient and practical, and die casting is given birth to
Production. art process monitoring practicality is stronger.This device can also be generalized in other Die Casting auxiliary equipments, similar vacuum
Machine（Die sinking in place, matched moulds in place, injection signal, public end signal choose）Deng, for extrusion process production provide it is more reliable more
The scheme of automation.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any to be familiar with this professional technology people
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, as long as being the content without departing from technical solution of the present invention, the technical spirit according to the present invention
Any simple modification, equivalent change and modification made to above example, in the range of still falling within technical solution of the present invention.
