Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Embodiment one:
As Fig. 1, shown in Fig. 3, the Novel casting mould knockout head of the present embodiment, comprise holder 1, the upper surface of holder 1 is provided with lift cylinder 2, its lower surface is provided with many plunger tips 3, the position of plunger tip 3 is corresponding with the position of sand-spraying hole, holder 1 is the hollow-core construction with inner chamber 100, its upper surface is provided with the air inlet pipe 4 be communicated with its inner chamber 100, air inlet pipe 4 is provided with solenoid valve 12, the controller 10 of solenoid valve 12 is connected with timing controller 11, start by set date module is provided with in timing controller 11, start by set date module sends signal according to setting-up time to controller 10, controller 10 controls the aperture of solenoid valve 12 according to the signal received, the upper end of plunger tip 3 is rotationally connected by bearing 6 and mounting head 5, and mounting head 5 and holder 1 are connected, plunger tip 3 is the tubular structure with air guide channel 30, its sidewall is communicated with and multiple jet orifices 31 setting up and down with its air guide channel 30, the inclined of the relative plunger tip 3 of jet orifice 31 is arranged downwards, spacing between adjacent jets hole 31 increases from top to bottom gradually along plunger tip 3, the lower end of plunger tip 3 is closed by termination 7, the inwall of termination 7 is provided with helical blade 8, helical blade 8 is air vane sheet, under the promotion of air-flow, drive termination 7 to rotate, the outer wall of termination 7 is provided with soft erasing cover 9, the maximum outside diameter of soft erasing cover 9 is greater than the internal diameter of sand-spraying hole, mounting head 5 is with the venting cavity 50 of communication with cavity 100 with air guide channel 30, and the internal diameter of venting cavity 50 is greater than the internal diameter of air guide channel 30.Venting cavity 50 transits to air guide channel 30, and overall formation one throat structure, increases the air pressure of air guide channel 30, thus increases the injection pressure of jet orifice 31.
During work, lift cylinder 2 promotes plunger tip 3 and stretches in sand-spraying hole, and the sand in soft erasing cover 9 pairs of sand-spraying holes is tentatively removed; Air inlet pipe 4 is connected with air pump, in holder 1, import high pressure draught, and air-flow is spouting from jet orifice 31 after air guide channel 30, sprays into in sand-spraying hole, sand punching is wherein fallen; When air-flow is directed into the lower end of plunger tip 3, air-flow punching press is on the helical blade 8 of termination 7, and under the effect of airflow thrust, plunger tip 3 along with carrying out rotation in termination 7, thus realizes carrying out rotary Air blowing cleaning to sand-spraying hole.Timing control module is provided with in timing controller 11, with many grades of times in described timing control module, as third gear is set: gear interval time is 3 seconds, namely often sent a signal through 3 seconds to controller 10, after controller 10 receives signal, the aperture of solenoid valve 12 is regulated once; After three times regulate, the aperture of solenoid valve 12 is maximum; Thus realize carrying out gradual change type adjustment to the air pressure in inner chamber 100, final realization carries out gradual blowing to the sand in sand-spraying hole.Compare the removing of constant expulsion pressure, its effect is better, the kicking up in a large number of sand when avoiding directly blowing down with peak injection pressure, finally improves blowing efficiency and effect.
Embodiment two:
As shown in Figure 1 and Figure 2, the Novel casting mould knockout head of the present embodiment, the improvement comparing embodiment one is, the inner of jet orifice 31 is with flare 32.Enlarging 32 horn-like, is beneficial to air-flow and enters jet orifice 31, reduces injection resistance.
