Description

Technical Field

[0001] The utility model relates to the technical field of die-casting of automobile parts, and more specifically, to a fast-demolding die-casting mold for automobile chassis parts. Background Art

[0002] Die-casting molds for automotive parts are important tools in the automobile manufacturing process. Since some parts in automobile manufacturing are difficult to be processed and formed later, some parts are manufactured by die-casting. Die-casting molds for automotive parts play a key role in lightweighting automobiles, reducing costs and improving production efficiency.

[0003] At present, after the existing die-casting molds for automobile parts are manufactured, in order to facilitate the removal of automobile parts, the molds generally need to eject the products after die-casting. When ejecting, one-time ejection is generally used to completely separate the automobile parts from the mold.

[0004] However, the one-time ejection and demolding method exerts a large force on the automobile parts, which may cause partial deformation of the automobile parts, thereby causing losses. At the same time, when the automobile parts are ejected, the demolding may be incomplete, requiring additional operations or adjustments, which cannot meet the needs of die-casting of complex parts. Therefore, a fast-demolding die-casting mold for automobile chassis parts is proposed to improve the existing problems. Utility Model Content
