In order to achieve the purpose, the utility model adopts the technical scheme that the novel inner and outer module for the lamp belt extruder comprises an inner die body and an outer die body, and is structurally characterized in that a forming port is formed in the outer die body, an inner die head penetrating through the forming port is arranged on the inner die body, an extrusion gap exists between the inner die head and the forming port, the inner die head comprises an inner die rod positioned in the forming port, the inner die rod is arranged around the central axis of the forming port, a core die column is inserted into the inner die body, one end of the core die column is surrounded by the inner die rod, and a forming gap exists between the core die column and each inner die rod.

Furthermore, the section of the inner mold rod is in a water drop shape.

Furthermore, the inner die body comprises a tapered cylinder part, a positioning plate connected with the inner die head is fixed at the small-caliber end of the tapered cylinder part, and a central opening used for penetrating through the core die column is formed in the positioning plate.

Furthermore, the large-caliber end of the cone cylinder part is connected with a straight cylinder body.

Furthermore, the contour of the molding opening is petal-shaped.

Furthermore, the outer die body is disc-shaped, and the outer die body is provided with a positioning connecting hole.

Compared with the prior art, the utility model has the beneficial effects that: when carrying out product extrusion moulding, can make the interior pore structure that forms of wall of product to reduce the materials cost, and the lamp area through this module output, light refraction, scattering that can make the wick distribute become many, and the halo grow makes whole lamp area seem softer, more hazy, have more the aesthetic feeling.
