1.Vibration knockout machine is a foundry equipment that makes use of vibration and impact (see mechanical vibration) to separate molding sand from casting.
2.The vibration sources of the sand-dropping machine are divided into three categories:
mechanical, electromagnetic and pneumatic.
3. The mechanical inertial sand-dropping machine is widely used (see Figure Inertia
Sand-dropping Machine). The structural characteristics of the inertial knockout machine are: the knockout grid bed is equipped with a rotating shaft with a bias. When the important official rotates, the bias generates centrifugal force (exciting force) to make the shakeout grid bed installed on the support spring vibrate.
4.This vibration is a motion combined with free vibration and forced vibration, and the magnitude of the load can change the amplitude. The load is too large, the amplitude decreases sharply,
and the sand falling efficiency decreases; the load is too small, the vibration is too large, and the flask and equipment are damaged. For this reason, a fixed bracket should be additionally installed on this type of sanding machine to form an inertial impact type sanding machine. During sand falling, the casting mold is placed on the support, the bottom surface of the casting mold and the sand falling grid bed have a gap, and the bottom surface of the casting mold is impacted by the vibration of the grid bed, so that the casting and the molding sand are separated. Since the casting mold is not directly placed on the shakeout grid, the influence of the change of the casting mold weight on the amplitude of the shakeout machine is relatively reduced. For small and medium-sized castings without box casting mold, drum-type sand falling machine can also be used, which is generally installed
on the production line of small and medium-sized castings without box casting mold. Besides sand falling, it also has the functions of hot sand cooling, old sand screening, sound insulation, heat insulation, dust removal, etc.
