An injection mold includes a mold body and an open-loop water channel. The mold body includes a molding surface and a number of side surfaces surrounding the molding surface, and a number of mold cavities defined in the molding surface. The water channel is defined in the mold body. An open end of the open-loop water channel serves as an inlet. The other open end of the open-loop water channel serves as an outlet. The inlet is configured for introducing water into the water channel. The outlet is configured for draining the water out of the water channel. Each of the inlet and the outlet extends through two different side surfaces. In addition, the inlet and the outlet are separated from each other by a base material of the mold body. |
