Method for taking out die pouring gate buffering pit movable materials

Abstract

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.

Description

technical field [0001] The invention relates to a method for taking out the live material of the deep cavity of the mold runner, in particular to a method for taking out the live material of the buffer nest of the mold runner, and belongs to the field of casting mold making. Background technique [0002] At present, the loose material of the mold sprue buffer nest is taken out by using the live material to leave a hole, and a small iron rod is used to take it out by hand. Because the size of the sprue is often too small to reach in, it is very difficult to take out the live material, and it is very dependent on the operator. experience, and it is very easy to damage the sand core, and it is necessary to repair the sand core again, resulting in a waste of time and material loss, and has a great impact on the quality of the sand core, which greatly reduces the efficiency of making sand cores; [0003] With the continuous improvement of sand core quality requirements, the requi...

[0002] At present, the loose material of the mold sprue buffer nest is taken out by using the live material to leave a hole, and a small iron rod is used to take it out by hand. Since the size of the sprue is often small and cannot be reached by hand, it is very difficult to take out the live material, and it is very dependent on the operator. experience, and it is easy to damage the sand core, and it is necessary to repair the sand core again, resulting in a waste of time and material loss, and has a great impact on the quality of the sand core, which greatly reduces the efficiency of making sand cores;

[0003] With the continuous improvement of sand core quality requirements, the requirements for production efficiency are getting higher and higher. The current method of taking out live materials is becoming more and more difficult to adapt to the current high-efficiency working conditions. Therefore, it is necessary to improve the method of taking out runner buffer nest live materials , reducing the loss of manpower and materials is very important to improve the efficiency of sand core production
