摘要: A method of casting a pipe having an axially elongate hole of which a front end is closed, comprises the steps of positioning a rod-like center pin for forming the blind hole in a predetermined positional relation to cavity defining surfaces of a die cavity, supporting the positioned center pin sidewise with a support pin to prevent positional deviation of the center pin, charging molten metal into the die cavity, retreating the support pin apart from the center pin, and replenishing a space formed by the retreat of the support pin with molten metal.
