Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A plastic straw extrusion molding die is shown in figures 1 to 5 and comprises a color-attached feeding base 1, a color separation plate 2 and a molding plate 3 which are arranged side by side in sequence, wherein a fixing locking screw 4 is connected among the color-attached feeding base 1, the color separation plate 2 and the molding plate 3; a truncated cone-shaped cavity 5 is arranged in the middle of the color-attaching feeding base 1 and the color separation plate 2, and a cylindrical die cavity 6 communicated with the cavity 5 is arranged in the middle of the forming plate 3; the middle parts of the cavity 5 and the die cavity 6 are provided with a die core 7, and the distance from the outer side wall of the die core 7 to the inner side wall of the cavity 5 and the die cavity 6 is the same.
