Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Embodiment one:
As shown in Figure 1, the gradual air blowing knockout head of the mold 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 10, its upper surface is provided with the air inlet pipe 4 be communicated with its inner chamber 10, air inlet pipe 4 is provided with solenoid valve 9, the controller 7 of solenoid valve 9 is connected with timing controller 8, start by set date module is provided with in timing controller 8, start by set date module sends signal according to setting-up time to controller 7, controller 7 controls the aperture of solenoid valve 9 according to the signal received, 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, and the spacing between adjacent jets hole 31 increases from top to bottom gradually along plunger tip 3, the lower end outer wall of plunger tip 3 is provided with soft erasing cover 6, and the maximum outside diameter of soft erasing cover 6 is greater than the internal diameter of sand-spraying hole.Soft erasing cover 6 is quality of rubber materials, has certain elastic deformation.
During work, lift cylinder 2 promotes plunger tip 3 and stretches in sand-spraying hole, and the sand in soft erasing cover 6 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.Timing control module is provided with in timing controller 8, with many grades of times in described timing control module, as third gear is set: gear interval time is 3 seconds, namely often sends a signal through 3 seconds to controller 7, regulates once after controller receives signal to the aperture of solenoid valve 9; After three times regulate, the aperture of solenoid valve 9 is maximum; Thus realize carrying out gradual change type adjustment to the air pressure in inner chamber 10, 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.
