Spliced barrel mould of glass steel storage tank

The utility model discloses a spliced barrel mould of a glass steel storage tank. A mould main body (1) is formed by splicing more than two arc column-shaped mould splicing pieces (11 and 12); a supporting keel (2) is fixed on outer walls of the mould splicing pieces (11 and 12); the supporting keel (2) comprises a plurality of axially-arranged circular arc-shaped support frames; an annular support frame (21) can be formed by the circular arc-shaped support frames after the splicing is completed; mould can be rotated under the support of the annular support frame (21); further, the annular support frame (21) can be arranged on more than two groups of support pulleys (5) which are arranged in pairs; the annular outer edge is aligned at a pulley (54); the annular support frame can roll along with the pulleys (5) to drive the mould main body (1) to rotate. By adopting the structure, not-spliced mould splicing pieces are conveniently transported and can meet the one-step molding requirement of the barrel after be
