Novel mold for producing double-matched-color straw

The invention discloses a novel mold for producing a double-matched-color straw. The novel mold comprises a mold connector, a mixing cavity and a straw extrusion channel, wherein the mixing cavity is arranged at the bottom of the mold connector; an inner cavity of the mixing cavity is sequentially provided with a first mixing spiral rod, a second mixing spiral rod and a third mixing spiral rod from top to bottom; the straw extrusion channel is arranged at the bottom of the mixing cavity; and a mold core is arranged in an inner cavity of the straw extrusion channel. Through the first mixing spiral rod, the second mixing spiral rod and the third mixing spiral rod which are arranged inside the mixing cavity, the mold can meet production and machining of the double-matched-color straw; meanwhile, as the first mixing spiral rod, the second mixing spiral rod and the third mixing spiral rod are each composed of a C groove and a D groove, when the double-matched-color straw is produced by the mold, fusion and splicing between A-color PP materials and B-color PP materials are more sufficient and uniform; and meanwhile, two colors of the double-matched-color straw produced by the mold are more uniform and symmetrical.
