Based on the finite element analysis software ABAQUS, the steady and transient temperature field of the high load press is analyzed, and the temperature field distribution characteristics of the ejector cylinder, the moving beam steel wire layer and the frame steel wire layer are obtained. The results show that the heat source can be effectively blocked by adding thermal insulation pad between the mold and the upper mold seat, which is better than the scheme of adding thermal insulation pad at both ends of the ejector cylinder, and the temperature control effect is obvious. The improvement of the surface heat transfer coefficient and the local surface heat transfer coefficient is not obvious for the improvement of the oil temperature.
