An injection mold (20) includes a female mold (22) and a male mold (24). The female mold defines a recess portion (222) therein. The male mold includes a mold core (242) and defines at least one main injection canal (2425) therein. The mold core cooperates with the recess portion to form a cavity (26) communicating with the main injection canal and configured for shaping workpieces. The main injection canal includes an injecting hole (2426) and an ejecting hole (2427) communicating with the injecting hole. The ejecting hole has a size larger than that of the injecting hole and is positioned to be proximate to the cavity.
