The invention provides a mold and method to produce a buried post-grouting precast pipe pile and is intended to produce a precast pipe pile of corresponding roughness as required so as to meet the needs of different pile foundation projects. The mold herein is characterized in that the mold as a pipe mold comprises: two semi-cylindrical half molds that are releasably fixed together to enclose a pipe cavity; two cover plates releasably covering upper and lower openings of the pipe cavity, wherein each half mold is provided with a plurality of rows of first mounting holes at equal intervals; a plurality of protrusions mating with the half molds and provided with second mounting holes corresponding to the first mounting holes; fasteners which help releasably attached the protrusions to predetermined positions of the inner surfaces of the half molds via the second mounting holes and the first mounting holes; and seals releasably mounted in the half molds and which help seal all the first mounting holes, having no protrusions, in the half molds.
