[0002] Cast iron is a metal material with certain material properties and strength properties. Cast iron parts are commonly found in workpieces such as low-pressure pipelines and shells. There is currently a centrifugal casting mold for cast iron parts, whose mold structure does not require an inner core. The centrifugal molding of the cast iron melt is achieved by rotating the mold during casting, so that the casting can complete crystallization and solidification more smoothly during cooling, and the gas in the melt can be effectively and thoroughly discharged. The centrifugal mold needs to be driven by a motor to rotate at a certain speed during operation, which requires the mold to have certain clamping and fixing properties so that the mold can withstand a certain centrifugal force when working, so that the mold can rotate smoothly. Therefore, most conventional centrifugal casting molds are set to a fixed installation structure, which makes it impossible to easily disassemble the mold after installation. For this reason, the mold structure needs to be optimized and improved. Utility Model Content
