Description

Stamping die with cooling structure

Technical Field

The utility model belongs to the technical field of stamping die, concretely relates to stamping die with cooling structure.

Background

Stamping die produces a large amount of heats relatively easily when carrying out the punching press work piece, thereby can pass on terrace die and the die that the heat arrived, and then can be very fast transmit upper and lower die holder, make the rapid rise of temperature of mould, the mould is at the in-process high temperature of long-term work can reduce the life of mould, consequently, need reduce the temperature of mould, current stamping die heat sink all adopts the water-cooled mode to cool down, cooling speed is not quick enough, and what will last circulates and cools down, thereby need consume more energy, for this reason, we propose a precision stamping die rapid heat sink.
