Summary of the invention
The utility model is to provide a kind of mold cools down control device at the defective that the above-mentioned background technology exists, it need absorb the principle of a large amount of heat energy by the gasification that utilizes water, use the reasonable arrangement of passage in the atomising device of a Ge water and the mould, when mold work, to the die steel internal spray, water is gasified at steel surface water smoke, thereby take away the heat in the die steel, by the compartment spraying, make mould temperature balance again, to improve the metal casting quality.
For achieving the above object, the utility model discloses a kind of mold cools down control device, it comprises water route valve C2, gas circuit valve C1, gas circuit valve C3 and control relay circuit, and this control relay circuit is electrically connected with described water route valve C2, gas circuit valve C1 and gas circuit valve C3.
Further, described control relay circuit is provided with following four branch roads:
1., dnockout finishes signaling switch K1 elder generation and meets the contact M11 of auxiliary reclay M1, is connected in series the contact CNT1 of counter cnt and the coil of auxiliary reclay M1 again;
2., the contact M12 of auxiliary reclay M1 is serially connected with the contact T1 of time relay T and the coil of time relay T, the coil of the coil of time relay T and output relay C also connects;
3., counter cnt one side connects the contact C11 of output relay C and the contact M13 of auxiliary reclay M1, another side joint power cathode respectively;
4., the coil of water route valve C2, gas circuit valve C1 and gas circuit valve C3 is connected with each other, be connected in series with the contact C12 of output relay C again.
Further, to finish signaling switch K1 can be magnetic valve, controllable silicon, triode or FET to described dnockout.
In sum, owing to adopted technique scheme, the utlity model has following advantage:
1, the reliability height is easy to implement, can adjust mold temperature by the number of times of spraying and the length in the time interval, makes the mold temperature balance, thereby realizes improving the castings production quality;
2, take away a large amount of heats by the gasification of water, thus using water wisely;
3, electric control circuit is simple, and one-time investment is less.
Description of drawings
Fig. 1 is the mold cools down schematic diagram of a kind of embodiment of the utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
The specific embodiment
For further understanding feature of the present utility model, technological means and the specific purposes that reached, function, the utility model is described in further detail below in conjunction with the accompanying drawing and the specific embodiment.
See also Fig. 1 and Fig. 2, a kind of mold cools down control device of the utility model comprises water route valve C2, gas circuit valve C1, gas circuit valve C3 and control relay circuit, and this control relay circuit is electrically connected with described water route valve C2, gas circuit valve C1 and gas circuit valve C3.
Described control relay circuit is provided with following four branch roads:
1., dnockout finishes signaling switch K1 elder generation and meets the contact M11 of auxiliary reclay M1, is connected in series the contact CNT1 of counter cnt and the coil of auxiliary reclay M1 again;
2., the contact M12 of auxiliary reclay M1 is serially connected with the contact T1 of time relay T and the coil of time relay T, the coil of the coil of time relay T and output relay C also connects;
3., counter cnt one side connects the contact C11 of output relay C and the contact M13 of auxiliary reclay M1, another side joint power cathode respectively;
4., the coil of water route valve C2, gas circuit valve C1 and gas circuit valve C3 is connected with each other, be connected in series with the contact C12 of output relay C again.It can be magnetic valve, controllable silicon, triode or FET that described dnockout is finished signaling switch K1.In the present embodiment, to finish signaling switch K1 be magnetic valve to described dnockout.
When using the utility model, described water route valve C2, gas circuit valve C1 and gas circuit valve C3 control water inlet pipe, air inlet pipe and the escape pipe of mould both sides respectively, the die cavity of described water inlet pipe and air inlet pipe and mould connects, described die cavity docks with many Fine pipe towards the firm material of mould, water route valve C2 and gas circuit valve C1 and gas circuit valve C3 open simultaneously during work, gases at high pressure and water mix in atomization chamber, form water smoke in mold cavity, and water smoke is penetrated to die steel Spray by many tubules; The water smoke that mixes forms water vapour when contacting with steel, thereby absorbs the heat of steel, and water vapour enters die cavity two by the gap between tubule and the hole, flows out by outlet pipe again; Whole Ge cyclic process is controlled by the control relay circuit of control opening and closing mould time and number of times, and timing when the charging of mould matched moulds, metering begin, and stop when mould is opened.
