Multi-water-channel hot stamping die

Abstract

A multi-water-channel hot stamping die includes an upper die base and insert, a lower die base insert. The upper and lower die bases are provided with a water channel, which is provided with die cavities, in which water through openings are arranged and in communication. A caliber of water through openings is smaller than die cavities, introducing turbulence into the cooling medium in the water channels and the die cavities thus improving cooling efficiency. Die cavities are arranged in the main water channel in a non-single straight line, water retaining blocks are placed at water through openings of the die cavities. A plurality of cooling zones is formed A plurality of inserts is correspondingly arranged in cooling zones, so that the of inserts are cooled simultaneously. Targeted control over cooling water flow of the main water channel is effected by supplying certain inserts with water.
