3 and floating in space, there is almost no heat transfer from the upper and lower molds through the pressure plate, so in order to raise the temperature of the upper and lower molds to the required temperature, the heating temperature must be low. In addition, the heating time can be shortened, and the temperature difference between the upper mold and the lower mold is small.

The temperature was measured at the 0 point in 7 and the change was shown. Even if the temperature at the 0 point is low, the temperature rises well without a large temperature difference between points A and B. I understand. On the other hand, Figure 4 shows the changes in temperature measured at point A of the upper die 102, point B of the lower die 103, and zero point of the heaters 116° and 117 in a conventional die forging device. However, it can be seen that even if the temperature at point 0 is increased, the temperature at points A and B is not increased satisfactorily, and a large temperature difference occurs between points A and B.
