Also comprise and be positioned at cope match-plate pattern and lower bolster, described cope match-plate pattern and lower bolster matched moulds form total die cavity, described total die cavity is communicated with two outlets in the first feed channel, annular material road, total die cavity exit on described cope match-plate pattern is provided with a breach, described indentation, there is provided with an adjustable insert, and described adjustable insert probes into the thickness of adjustable total die cavity in total die cavity; Described cope match-plate pattern is provided with a crane span structure, and described crane span structure and adjustable insert are fixed together by a roll adjustment stud, thus rotates the removable adjustable insert site of roll adjustment stud;
Also comprise a feed pipe, described feed pipe has two outlets import, and two outlets of feed pipe are communicated with two entrances in annular material road separately.
Further, described crane span structure is fixed on cope match-plate pattern across two pier studs, and pier stud and crane span structure are provided with perforation, and cope match-plate pattern is provided with screw, and described crane span structure, pier stud, cope match-plate pattern are fixed by screws in together.
Further, described roll adjustment stud comprises the section of expanding and is positioned at roll adjustment thread segment on front side of the section of expanding, is positioned at and expands the retaining thread section of end rear side, and described retaining thread end is screwed with nut through on crane span structure head; Described adjustable insert is provided with screwed hole, and described roll adjustment thread segment and screwed hole screw togather; Described adjustable insert is equipped with bar-shaped trough, and a described hold-down screw is fixed on adjustable insert on cope match-plate pattern through bar-shaped trough.
Further, described feed pipe becomes a curved pipe, and import is positioned on the mid point of curved pipe, and outlet is positioned at curved pipe two ends.
This strap two-color die head is arranged on plastic extruder by the utility model in use, and the first feed channel, feed pipe are connected with two kinds of plastic melt respectively, rotates the thickness that roll adjustment stud can adjust feed collet heart strap.
The beneficial effects of the utility model are: 1, without the need to changing insert or whole die head, regulate roll adjustment stud can the thickness of adjustable clamp heart strap smoothly.2, the existence in annular material road makes the heterochromatic melt distribution of both sides more even.
