Description

Technical Field

[0001] This utility model relates to the field of automotive hardware processing technology, specifically a direct-top die-casting mold for automotive hardware. Background Technology

[0002] In the processing of automotive hardware parts, die casting molds are typically required for forming. Die casting molds are tools used to cast metal parts. The basic die casting process involves molten metal being poured into the mold cavity at low or high speed. The mold has movable cavity surfaces that apply pressure as the molten metal cools, forging the metal and eliminating shrinkage cavities and porosity defects in the blank. This process also ensures the blank's internal structure achieves a forged, fragmented grain structure. However, existing die casting molds suffer from low workpiece cooling efficiency due to long cooling times.

[0003] To address the aforementioned issues, a direct-acting die-casting mold for automotive hardware parts is proposed. Utility Model Content

At the same time, the heat-exchanged coolant is introduced into the finned heat exchanger 13 through the liquid guide pipe 14.
