Description

Technical Field

[0001] The utility model relates to the technical field related to die-casting molds, and in particular to a die-casting mold capable of concealing a water channel. Background Art

[0002] During the continuous processing of the die-casting mold, the mold temperature rises. Due to poor heat dissipation, it is easy to cause slow product molding, prolonged demoulding time, and deformation of the product during the demoulding process, resulting in scrap.

[0003] Existing die-casting molds generally have water cooling channels in the molds, and then cool the molds by passing cooling water through the cooling channels. If cooling water is passed directly through the molds for a long time, the molds will be corroded and deformed due to the immersion of cooling water, causing the entire mold to be unable to continue to be used normally. At this time, the molds need to be replaced. In addition, if cooling water is passed directly through the cooling channels, once the cooling channels are blocked, they cannot be repaired. At this time, the molds also need to be replaced, which greatly increases production costs and is relatively inconvenient. Utility Model Content
