Abstract
A mold plate module includes a mold plate and an inserting block. The mold plate includes a first surface, a blind hole defined in the first surface, a through hole defined in a bottom surface of the mold plate in the blind hole, two mold cavities, and two first sub-runners. The two first sub-runners are defined in the first surface, and connect the corresponding mold cavities to the blind hole. The inserting block includes a second surface, a lateral surface, a block through hole defined in the second surface, and at least one second sub-runner defined in the second surface. The at least one second sub-runner communicates with the block through hole and extends toward and terminating at the lateral surface. The inserting block is detachably received in the blind hole and rotatable relative to the mold plate to switchingly couple the at least one second sub-runner with the first sub-runners.
