Description

Technical Field

[0001] The utility model relates to the technical field of sand casting, in particular to a sand box manufacturing tooling frame for castings. Background Art

[0002] The so-called sand casting is a casting method that produces castings in sand. Before casting, a sand box of corresponding specifications must be manufactured according to the structural dimensions of the casting to be produced. At present, sand box processing is mostly carried out directly on the ground or on a platform without special tooling, and the sand box is inconvenient to carry. Since the shape and size of the sand box are determined according to the shape and structure of the casting, the sand box and the casting are in a one-to-one correspondence. Therefore, the traditional sand box processing method requires another work platform to be occupied when manufacturing the sand box, which occupies a large space, and the fixation of the sand box cannot be adjusted, resulting in a large waste of tooling, increasing production costs and reducing production efficiency.

[0003] Therefore, it is necessary to redesign the sand box manufacturing tooling frame for castings to solve the problem of increased production costs due to its non-adjustability. Utility Model Content
