After that, the die-casting raw material is poured into the inside of the feed hopper 25. When the die-casting raw material needs to be added to mold 2 18, the raw material enters the feed pipe 24 through the feed hopper 25. After the raw material is added, the electric push rod 22 drives the piston 23 to move forward and enter the mold cavity of mold 2 18 through the feed hole. After the die-casting process is completed in mold 10, the telescopic rod 12 drives the top plate 13 and the ejector rod 14 thereon to move forward.

After the die-casting falls on the conveying belt 4, the gravity squeezes the movable rod 7, causing the movable rod 7 to slide in the sleeve 5 and compress the spring 6. The spring 6 absorbs a certain impact force under the cooperation of the damper, reducing the impact force when falling to cause scratches, deformation or other damage on the surface of the die-casting, thereby improving the processing accuracy of the die-casting;

[0030] When the die-casting is transported out from the conveyor belt 4, it will fall into the buffer plate 27 in the collection box 26. At this time, the negative pressure motor 29 is started so that its output end drives the fan blades 30 to rotate, and the outside air is cooled by the collection box 26 through the air inlet hole 31, thereby further cooling the die-casting, so that the die-casting can be completely cooled.
