Description

Technical Field

[0001] The utility model relates to the technical field of lost foam casting, in particular to a vibrating table for lost foam casting production. Background Art

[0002] The vibrating table for lost foam casting is an advanced casting equipment. It uses vibration technology to effectively compact the sand filling in the lost foam casting process. This equipment is increasingly widely used in the casting industry and has become an important tool for improving casting efficiency and product quality. The vibrating table for lost foam casting usually consists of a table, a vibration system, a control system and other parts. The table is used to place the sand box and the molding sand. It is required to have good rigidity and stability and be able to withstand vibration and pressure. The vibration system is the key part to achieve the compaction of the sand filling. It is usually driven by electromagnetic or electric means and can generate vibrations in both vertical and horizontal directions. The control system is responsible for controlling and adjusting the entire equipment, including The setting and adjustment of parameters such as amplitude, frequency, and time. In the lost foam casting process, the application of the vibrating table can greatly improve the efficiency and uniformity of sand filling compaction, thereby reducing the use of molding sand and improving production efficiency. At the same time, due to the improvement of the compaction of sand filling, the cast products are more uniform and dense, which improves the product quality. In addition, the vibrating table can also reduce the labor intensity of workers. However, the existing vibrating tables are equipped with driving mechanisms for vibration in different directions. These driving mechanisms need to vibrate synchronously with the table surface in order to cooperate with the movement of the table surface without being separated from the table surface. This will cause the components of the driving mechanism to loosen after working for a long time, thereby reducing the service life of the driving mechanism. Utility Model Content
