[0002] The casting mold is a tool for forming the structure shape of a part. In the casting process, first, a structure shape of a part is made using other easily formed materials, i.e. a mold. Then the mold is placed in a sand mold, which forms a cavity consistent with the structure size of the part according to the shape of the mold. Next, a liquid material with good fluidity is poured into the cavity, and after it cools and solidifies, a part with the same structure and shape as the mold is formed. In existing casting technology, in order to prevent the pouring frame from shaking during pouring and causing uneven liquid level inside the mold, a shock absorbing support structure is usually added at the bottom of the mounting frame.
