Disclosed is a shaping mold for products with a circular hole, comprising a male mold and a female mold corresponding thereto, forming a core cavity therebetween after the shaping mold is closed. A pin mold core and a female mold core capable of dipping into the core cavity are in the male mold and female mold respectively. A mating face of the pin mold core and the inner face of a square hole shaping portion of the female mold core compress with each other after the shaping mold is closed. With the limitation head and the limitation boards buckling up, the shaping mold of the present invention restricts the pin mold core not rotated in the core cavity to prevent dislocation of the mating face and the square hole shaping portion happening during the insert and shut off operation. Accordingly, the shaping accuracy of the products can be guaranteed.
