The micro-vibration compaction molding machine can vibrate the molding plate, the sand box and the molding sand with high frequency and small amplitude while the molding sand is compacted. When the sand box is filled with loose molding sand, there are still many gaps between the sand grains. At this time, the template is directly vibrated, and energy is transferred to the sand grains, so that they can find a new equilibrium position in the continuous movement, thereby filling the gaps. Improve its firmness. When additional vibration is continued during the compaction process, in addition to the above effects, the external frictional resistance between the sand particles and the inner wall of the sand box can be reduced, and the compaction effect can be further increased. Therefore, additional vibration can significantly improve the phenomenon of uneven compaction during compaction. Simultaneous micro-seismic compaction can also achieve a higher average compaction than simple compaction. Because micro-seismic can improve the fluidity of the molding sand during the compaction process, it can achieve a higher average compaction than simple compaction with the same compaction ratio. The average compactness and a more even compaction distribution.　The micro-vibration compaction molding machine can not only perform micro-vibration during compaction, but also perform micro-vibration during the sand adding process, which is the so-called pre-shock before compaction. This can increase the amount of sand in the sand box and improve the original compactness and uniformity of the sand mold; it can reduce the height of the pre-filling frame and reduce the stroke of the compaction piston, especially for high sand boxes or complex models. Favorable shape.
