[0002] The hot forging casting process of products has a wide range of applications, from military aerospace parts to civilian valve plastic parts. The hot forging process is applied, and the hot forging process is implemented by hot forging dies. Common hot forging dies are mainly composed of an upper die and a lower die. The upper die is installed on the stamping equipment, and the forging blank is set on the lower die. There are product cavities between the upper and lower dies that are combined into one to form the appearance of the hot forged product; therefore, when the upper die is combined with the lower die by the stamping equipment, the forging blank can be stamped and forged into shape through the product cavity, thereby completing a hot forging casting.

[0003] Among them, it was found through searching that the patent application number CN201621466607.X discloses a hot forging die, including an upper die, a lower die and a forging blank arranged between the upper and lower dies, the upper die bottom surface and the lower die top surface are respectively provided with a product cavity that is combined into one to form the appearance of the hot forged product, the upper die bottom surface is provided with a waste edge groove located on one side of the product cavity, and the lower die top surface is also provided with a waste edge groove located on one side of the product cavity; a reserved spacing is provided between the waste edge groove and the contour edge of the product cavity;

The improved structure can effectively improve the forming success rate of complex-shaped products during hot forging, but this structure is not easy to discharge the hot-forged product from the mold when in use, resulting in inconvenient material guiding.
