Description

Technical Field

[0001] The utility model relates to the technical field of equipment manufacturing, in particular to a sand mold vibrating device. Background Art

[0002] Resin sand refers to molding sand or core sand that uses artificial synthetic resin as a binder for sand particles. After the resin sand is used to make a mold or core, the resin undergoes an irreversible cross-linking reaction and solidifies through the action of a curing (hardening) agent, thereby giving the mold or core the necessary strength.

[0003] After searching, it was found that the publication number is CN218134822U, and the name is a sand mold vibration compacting device. The application proposes that for modern resin sand production batches of small and medium-sized pieces, most manufacturers use a vibration platform to compact the sand mold, but for large pieces and small batches, manual operations mainly rely on manual sand pounding, which is affected by human factors. The effect is poor and the compaction range is inconsistent. By spreading resin sand on the surface of the sand box and rotating the bolts to tightly press the bolts against the connecting plate, the connecting plate is tightly pressed against the sand box, and the limit at the bottom of the U-shaped fastening card is used. The U-shaped fastening card, the connecting plate and the sand box are fixed in relative position, and the vibration motor on the surface of the connecting plate is started. A vibration motor is added to the sand box as a vibration source when the sand is placed in the molding. The vibration source resonates with the resin sand as a whole to achieve the effect of vibration compaction. The compaction effect is good and the compaction range is uniform. However, the application still requires manual fixing operation by the staff, which is more troublesome. At the same time, the vibration motor vibrates on one side, the vibration coverage range and comprehensiveness are not high, the compaction efficiency is low, and the vibration transmission uniformity is not good, which affects the production efficiency. Further improvements can be made.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
