[0016] Preferably, a connecting hole is provided at the top of the upper mold.

[0017] The working principle and beneficial effects of the utility model are:

[0018] 1. In the utility model, the electric push rod is extended and retracted to drive the bottom end of the second fixing rod to move, so that the first clamping groove opened at the top clamps and fixes the lower die, replacing manual labor and improving accuracy. Moreover, the three-point fixing method allows the die forging to maintain a stable position during the processing. By applying clamping force at multiple points of the workpiece, the vibration and deformation of the workpiece can be effectively reduced, and the processing accuracy and surface quality can be improved;

[0019] 2. In the utility model, the extrusion ring is moved upward by the up and down movement of the sliding sleeve, thereby canceling the clamping fixation of the limit ball, thereby canceling the clamping fixation of the limit ball and the second clamping groove, so that the limit column can be pulled out of the limit sleeve, and the upper die and the lower die are quickly separated. In the process of die forging, the upper die and the lower die need to be frequently replaced to meet the processing requirements of different workpieces. The use of a fixing fixture that quickly separates the upper die and the lower die can greatly shorten the die change time, thereby improving production efficiency. Workers do not need to spend too much time on tedious operations, and can complete the mold replacement faster, reducing the downtime of the production line and improving production capacity.
