[0002] Centrifugal casting is a technique and method of injecting liquid metal into a high-speed rotating mold, so that the molten metal performs centrifugal motion to fill the mold and form a casting. Due to the centrifugal motion, the liquid metal can fill the mold well in the radial direction and form a free surface of the casting; a cylindrical inner hole can be obtained without a core; it helps to remove gas and inclusions in the liquid metal; it affects the crystallization process of the metal, thereby improving the mechanical and physical properties of the casting.

[0003] Existing pipe molds generally adopt the method of machining support wheel grooves on the pipe mold body. This design method makes the pipe mold thick and costly, and has a great impact on the rigidity and toughness of the pipe mold. The pipe mold has a short service life, is heavy, and does not run smoothly at high speeds. The pipe mold also has large vibrations, which affects the intrinsic quality of the cast pipe and cannot ensure that the mechanical properties and metallographic structure meet the standard requirements.
