A mold assembly includes a male mold, a female mold, and a driving unit. The male mold includes a stationary member, a moveable member defining through holes, and mold cores fixed on the stationary member and received in the respective through holes. The female mold covers the moveable member. The female mold defines recesses aligned with and communicating with the respective through holes. The moveable member, the female mold and the mold cores cooperatively form mold cavities at the through holes. The driving unit is fixed on the stationary member and supports the moveable member. The driving unit is configured for driving the moveable member to move upward or downward along the mold cores relative to the stationary member. |
