High-temperature-resistant sillimanite pouring forming mold

The utility model discloses a high-temperature-resistant sillimanite pouring forming die which comprises an upper pressing die, an upper pressing plate and a lower bottom die, a material output pipe is arranged in the upper pressing die, the tail end of the material output pipe is arranged on the upper pressing plate, the material output pipe is communicated with a material inlet, the upper pressing die moves downwards through a hydraulic telescopic assembly, and the upper pressing plate is pressed against the top face of a forming groove in the lower bottom die. According to the sillimanite forming device, a closed forming space is formed, sillimanite mixed materials are output into a forming groove through a material output pipe, the problem that pores of formed sillimanite are not uniform is solved, an air inlet pipe is arranged in a hollow cavity in the outer wall of the forming groove and communicated with the forming groove through an air injection pipe on the air inlet pipe, and air pressure is output
