Abstract: The present patent application provides a flower pot mold for blow molding. The mold can reduce the number of the sliding blocks that need to be moved, and utilize the motion of a single sliding block to mold a flower pot so as to improve the manufacturing efficiency and the product quality. The mold includes a flower pot cavity template; a container opening pulling mold; a plurality of opening flanged pulling plates, a blowing tube being disposed in the container opening pulling mold; a fixing plate configured for fixing the mold onto a clamping set; a guiding block configured for guiding the opening flanged pulling plate and a blocking plate; and the blocking plate configured for blocking the plastics. A sliding track is formed on the flower pot cavity template and configured for allowing the blocking plate to move back and forth.
