PURPOSE: A rotary mold for a tent pole is provided to prevent foreign materials from flowing into upper and lower molds and to securely support the upper and lower molds. CONSTITUTION: A rotary mold for a tent pole comprises upper and lower latching protrusions(103,113), and a collar. The upper latching protrusion is installed on the bottom surface of an upper mold(101) and restricts the upper mold and a lower mold(111) to be rotated within a predetermined range. The lower latching protrusion is installed on the top surface of the lower mold and is rotated within a predetermined range. The collar securely supports the upper and lower molds and prevents foreign materials from flowing into the upper and lower molds. |
