AI Technical Summary

Technical Problem

The low cooling efficiency of existing mold steel leads to excessively high temperatures in the main body of the mold steel, affecting its stable operation under complex working conditions such as high temperature and high pressure.

Method used

Multiple first and second through slots are opened on the main body of the mold steel, and connecting steel frames are set at the top and bottom and fixed by fixing bolts. The outer side is equipped with a buffer component to improve stability. At the same time, a support layer of high-strength alloy material, a corrosion-resistant Ni-P alloy layer and a wear-resistant PVD coating material are used.

Benefits of technology

It achieves efficient heat dissipation of mold steel, improves the stability and wear resistance of mold steel, prevents corrosion, and ensures long-term stable operation under complex working conditions.

Abstract

The utility model discloses die steel with a porous cooling structure, and particularly relates to the technical field of die steel, the die steel comprises a die steel main body, the die steel main body is provided with a plurality of first through grooves and a plurality of second through grooves, and the plurality of second through grooves are respectively communicated with the plurality of first through grooves. Connecting steel frames are movably arranged at the top and the bottom of the die steel body correspondingly, three fixing bolts are arranged on the opposite sides of the two connecting steel frames correspondingly, and the two connecting steel frames and the die steel body are fixed through the multiple fixing bolts correspondingly. According to the die steel, the multiple first through grooves are formed, cooling media can circulate in the multiple first through grooves, the heat dissipation effect of the die steel body can be improved, when oil, water and other liquid media exist, the multiple second through grooves can store the oil, water and other liquid media, the oil, water and other liquid media can be rapidly released when the local temperature of the die steel body rises, and the multi-hole cooling structure is arranged; and heat dissipation of the die steel body is facilitated.
