Description

Technical Field

[0001] The utility model relates to the technical field of mold casting, in particular to a rapid loading and unloading device. Background Art

[0002] In the casting process of ductile iron molds, after metal materials such as iron and steel are melted into molten iron in the smelting furnace, they need to be poured into a ladle from the smelting furnace, and then the ladle is transported to the casting area. The ladle is turned over by a crane and the molten iron is poured into the molding tooling to wait for cooling and molding. The casting also needs to be sanded after molding.

[0003] The utility model patent with the publication number of "CN209935835U" discloses a vibrating sand-falling device for fast loading and unloading, which is mainly composed of a frame, a sand-falling box, a vibration spring, a driving rod, a vibration motor and an eccentric wheel. This technical solution has the advantages of fast loading and unloading, and solves the problem that the prior art generally uses a sand-falling machine to perform sand-falling treatment on castings, which generally places the castings in a box, and then uses the vibration principle to separate the sand blocks from the castings, and then takes the castings out of the box. However, each time the castings are taken out, they need to be manually taken out and placed from the box opening of the box, which is labor-intensive and has low production efficiency.

[0004] The vibrating sand-falling device for rapid loading and unloading disclosed in the above document has the following defects: during use of the vibrating sand-falling device for rapid loading and unloading, the operator needs to directly contact the machine when taking the casting, so the process of taking the casting is relatively dangerous.

[0005] It can be seen from this that the existing vibrating sand-falling device for rapid loading and unloading does not have a structure that is convenient for taking out castings, and it is necessary to improve the existing deficiencies and provide a rapid loading and unloading device.
