Abstract
A mold for traffic cones has a female mold, a male mold and two cavities. Because each first annular recess of the female mold and a corresponding second annular recess of the male mold can hold a base of the traffic cone steadily, the female mold does not have to be placed under the male mold. Then the sprue can be formed through the female mold and can be nearby the two cavities. Besides, the distributing recess of the male mold communicates with the sprue and the second annular recesses. As a result, a liquid plastic material injected from the sprue is distributed and flows into the two cavities. After the male and the female molds are separated, two traffic cones are completed. Therefore, the mold for traffic cones as described can make two traffic cones at a time, which raises manufacture efficiency.
