[0043] Specific working principle:

[0044] The central control platform 9 is turned on so that the second motor 62 connected to the central control platform 9 starts to work, and the second motor 62 drives one of the gears 66 to operate. The gear 66 connected to the second motor 62 drives the gear 66 connected to the roller 64 to operate, thereby driving the roller 64 to rotate. The two rollers 64 rotate in opposite directions. At this time, the large aluminum material is added from the feeding port of the crushing box 63, and after being crushed by the roller 64, it passes through the discharge port 65 and falls onto the placement plate 82 inside the storage box 81. The continuous falling of aluminum debris causes the placement plate 82 to compress the spring 83, so that the horizontal surface of the placement plate 82 continues to drop until the interior of the storage box 81 is almost filled. The weight sensor 91 on the outer wall of the discharge port 65 senses the weight change of the storage box 81, thereby sounding an alarm and conveying the information to the central control platform 9. The central control platform 9 issues a command to stop the second motor 62 from working, and issues a command to stop the first When the motor 31 starts to work, the first motor 31 drives the hydraulic push rod 3 to work. The hydraulic push rod 3 passes through the extrusion port 811 to extrude the aluminum debris to the mold on the pressure plate 76 and the placement groove 75, and finally falls into the collecting groove 712; when the mold needs to be replaced, the central control platform 9 is closed, and the handle 714 is pulled to make the slide bar 711 slide inside the first slide groove 22 until the two-way screw rod 742 moves to the extreme end of the second slide groove 23 close to the baffle 21. At this time, the lifting plate 73 is just aligned with the replacement port 77, and then the handle 7421 is turned to make the two-way screw rod 742 rotate, thereby driving the two sliders 743 to move relative to each other, thereby reducing the angle between the two connecting rods 744, and finally driving the lifting plate 73 and the placement groove 75 to rise slowly, and the sleeve rod 731 rises slowly, so that different molding molds can be used, and the molds can be frequently replaced during work, thereby ensuring the production of a variety of different molding aluminum materials in a short time, thereby improving the molding diversification efficiency.
