MOLD ASSEMBLY

摘要

A mold assembly includes an upper mold and a lower mold. The upper mold defines an upper mold cavity. A plurality of punch pins are movably mounted in the upper mold. A channel is defined in the upper mold and in communication with the upper mold cavity. The lower mold is closed with the upper mold. The lower mold defines a lower mold cavity together with which the upper mold cavity forms a closed cavity. The closed cavity receives a work piece located therein. The mold assembly is movable between a first position and a second position. In the first position, the punch pins of the upper mold are punched into the work piece to from the work piece into predetermined shape. In the second position, the punch pins are moved out of the upper mold cavity. Molten plastic flows in the closed cavity via the channel to from plastic ornaments on the work piece.
