Trapezoidal PP corrugated pipe forming die

The trapezoidal PP corrugated pipe forming die is made of steel, the left die block and the right die block which are in mirror image with each other are formed according to the specification of a trapezoidal PP corrugated pipe, and the left die block and the right die block are combined into a trapezoidal through groove; ring grooves with trapezoidal sections are formed in the groove surface in the trapezoidal through groove at intervals; and a vacuumizing suction hole leading to the through groove is formed in the center of the top after the left module and the right module are combined. The trapezoidal PP corrugated pipe has the beneficial effects that the trapezoidal PP corrugated pipe produced by the device is high in rigidity and good in flexibility, the trapezoidal structure is narrow at the upper part and wide at the lower part, the stability is good, and the trapezoidal PP corrugated pipe can be bent and rotated when the corrugated shape and the height are large, so that the trapezoidal PP corrugated
