Hot compression molding die for titanium alloy hemispherical seal head

The invention relates to the field of hemispherical seal head forming dies, and particularly discloses a titanium alloy hemispherical seal head hot compression molding forming die which comprises a hemispherical lower die and a spherical upper die located above the hemispherical lower die, the spherical upper die is fixedly arranged at the bottom of a pressure rod of a press machine and fixedly assembled at the bottom of the pressure rod, and the spherical upper die is fixedly assembled at the bottom of the pressure rod. A base used for supporting is further fixedly installed at the bottom of the hemispherical lower die, and an electrified vortex line is fixedly installed in the hemispherical lower die. According to the invention, the interlayer is designed in the semispherical lower die, and the electrified vortex-shaped line capable of being electrified is additionally arranged in the interlayer, so that when the electrified vortex-shaped line works, an alloy containing a carbon element can be heated throug
