The specific embodiment

In conjunction with accompanying drawing and embodiment the dual channel profile shapes mould structure of the utility model is explained.

The dual channel profile shapes mould structure of the utility model is; This mould includes back die body, flow distribution plate, supporting plate, preformed board and profiled sheeting; Be provided with the groove 2 of twice tilting bottom land in the sector region both sides of the edge that the charging aperture 1 with said preformed board intersects; The groove of said tilting bottom land is the streamlined groove of arc, and the inclination angle of groove bottom land is 10 degree.Be provided with the parallel groove parallel 5 apart from said sector region bottom margin 1.5 centimeters with the sector region bottom margin; 5 millimeters places of direction in the bottom of the capable groove 5 of anomaly near principal mode material fusion face 3 are provided with arc notch 6; Form arcuate region between arc notch 6 and the principal mode material fusion face 3, the degree of depth of this arcuate region is greater than the degree of depth in gap 7 between arc notch 6 and the parallel groove 5; The thickness of said profiled sheeting is 30-40mm, and preformed board is in the same place by bolt earlier with profiled sheeting, runs through to be fixed on the die body of back forming integral body more successively through bolt and flow distribution plate, supporting plate.
