The invention relates to a method for taking out the live material of the buffer nest of the mold sprue, comprising: step 1, using the principle of leverage to manufacture a tooling support rod and a tooling rotating rod, and fixing a magnet at one end of the tooling rotating rod; the tooling rotating rod and the tooling support The rod is connected by a rotatable shaft; step 2, when designing each live material, the loose material is designed in hollow, and a magnet is fixed in the middle of the live material in advance, and the magnetic poles are calculated; step 3, when taking the live material, turn the rod One end with a magnet extends into the cavity, so that the magnet of the rotating rod is attracted to the magnet of the live material Ⅰ, and then slowly rotates the rotating rod to drag the live material out; step 4, the live material Ⅰ and the live material Ⅱ are connected by positioning pins , when using the tooling to take the live material Ⅰ, it will drive the live material Ⅱ to the previous position of the live material Ⅰ. At this time, take out the live material Ⅰ downward, and the live material Ⅱ will stay at the previous position of the live material Ⅰ, and then use the same The method is to take out the live material II. The beneficial effects of the invention are: improving efficiency, reducing cost, and convenient operation.
