摘要： A utility pole mold including an elongated, hollow mold body having an internally tapered end and a reservoir extending radially out therefrom. A reusable barrier member is detachably secured to the at least one wall opposite the tapered end for containing a molten metal within the reservoir. In use, a lance is inserted into the mold body and a pouring end of the lance is positioned about the reservoir. The mold body and reservoir are then rotated, and the molten metal is poured from the pouring end at a constant rate. As the lance travels along the length of the mold body at an accelerating rate, a continuous layer of the molten material is deposited within the mold body and the reservoir. Following casting, the barrier is removed from the reservoir, and the newly formed utility pole is removed from mold. That portion of the pole that was formed within the reservoir portion is then removed to provide a pole having a bottom end with a desired wall thickness and interior taper.
