Description

Technical Field

[0001] The utility model belongs to the technical field of numerical control processing, and in particular relates to an auxiliary tooling for CNC numerical control processing of die castings. Background Art

[0002] Die casting is a kind of pressure-casting part. It uses a pressure casting machine equipped with a casting mold to pour liquid metals such as copper, zinc, aluminum or aluminum alloy into the inlet of the die casting machine. The die casting machine is die-cast to cast copper, zinc, aluminum or aluminum alloy parts in the shape and size limited by the mold. Such parts are usually called die castings.

[0003] At present, when auxiliary tooling is used to clamp die-castings, it is not easy to adjust the length and diameter of the die-castings accordingly, resulting in unstable clamping and fixation of the die-castings. This causes the processed die-castings to shake easily, affecting their processing quality. After processing one side of the die-casting, it needs to be manually removed and turned over, which seriously affects the processing efficiency and is very inconvenient to use.

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