The invention relates to a rotary double-color mold structure. The rotary double-color mold structure comprises a sliding block, an inclined guide post, bullet cores and springs. The sliding block isprovided with a containing cavity allowing the inclined guide post to penetrate through. The two sidewalls of the sliding block are provided with mounting cavities oppositely. Each mounting cavity isinternally provided with a through hole allowing one bullet core to penetrate through. The through holes are connected with the containing cavity. The springs are located in the mounting cavities. Theouter walls of the bullet cores are sleeved with the corresponding springs. The outer wall of each bullet core is provided with an abutting block abutting against the corresponding spring. One end ofeach spring abuts against the corresponding abutting block, and the other end of each spring abuts against the corresponding mounting cavity. One end of each bullet core penetrates through the corresponding through hole into th
