the balance being aluminum;
in the proportion, silicon can improve the fluidity of the alloy, reduce the shrinkage rate, enable the injection process to be smoother, and improve the wear resistance of the alloy after molding to a certain extent, while the addition of copper plays a role in solid solution strengthening, so that the hardening strength of the thin-wall aluminum alloy is increased, the addition of a small amount of magnesium further strengthens the strength and reduces the specific gravity, and the addition of manganese plays a role in supplementary strengthening, so that the hot cracking tendency is reduced, and the corrosion resistance of the finished product is improved.
The working principle is as follows: when the die casting machine is used, molten aluminum alloy is placed into the crucible 43, the hydraulic cylinder 10 is driven to operate, the movable die holder 7 moves towards the fixed die holder 6 until the molten aluminum alloy and the molten aluminum alloy are completely attached, the injection cylinder 48 drives the injection punch 49 to operate, the injection punch 49 vertically moves downwards to push molten aluminum in the gooseneck 45 to enter the flow guide groove 42 and spread into the flow guide ring 603 and the four first die cavities 606 and the four second die cavities 701 along the peripheral flow guide channels 602, after the molten aluminum is cooled, the hydraulic cylinder 10 retracts to drive the movable die holder 7 to be separated from the fixed die holder 6, after the molten aluminum is cooled, the first stepping motor 14 drives the ball screw guide rail 13 to operate, the belt guide rail 19 on the sliding block 18 to move above the movable die holder 7 and the fixed die holder 6, the second stepping motor 20 drives the support arm 22 on the sliding table of the belt guide rail 19 to move downwards, and the grabbing mechanism 26 reaches the die casting position formed by the flow guide ring 603 in the center of the fixed die holder 6, then the belt transmission mechanism 30 drives the pneumatic four-jaw chuck 35 to rotate, and faces four jaw grooves 607 around the guide ring 603, the air cylinder 32 drives the pneumatic four-jaw chuck 35 to extend out, so as to clamp the die casting of the guide ring 603, and take the die casting out of the fixed die holder 6, because the periphery of the die casting of the guide ring 603 is connected with four thin-wall aluminum alloy die casting through four thick runners 604 and conical runners 605, so that four workpieces can be simultaneously taken down at a time, after the die casting is taken down, the ball screw guide rail 13 runs to drive the die casting assembly to move above the conveyor belt 50, the belt transmission mechanism 30 drives the pneumatic four-jaw chuck 35 to deflect downwards, so as to place the articles on the conveyor belt 50, then the ball screw guide rail 13 drives the supporting arm 22 assembly to move between the movable die holder 7 and the fixed die holder 6 again, after the height is adjusted, the temperature detecting probes 28 at the front end and the rear end are used for detecting the temperature in the die holder 6 and the movable die holder 7 respectively, and feeding back temperature information to the terminal, dividing the high-temperature area based on the image acquisition technology terminal, feeding back the information to the pumping mechanism after the division is finished, communicating the cooling gas tank by the pumping mechanism, conveying cold gas to the nozzles 27 at the corresponding positions on the spot spray cooling mechanism 24 for spraying, realizing the fixed-point efficient cooling of the high-temperature area, conveniently and quickly carrying out the next die-casting work, and repeating the steps after the movable die base 7 is cooled to the fixed die base 6, thereby realizing the continuous processing and forming of the aluminum alloy die-casting piece.
