Detailed description of the invention

As illustrated in fig. 1 and 2, a kind of extrusion die of MULTILAYER COMPOSITE building board, includes the first die body 1, second die body 2, the 3rd die body 3 and the 4th die body 4 that sequentially superpose.

First die body 1 front end is provided with die lip 5, and the front end of the second die body 2 and the 3rd die body 3 is provided with core rod 7, and the front end of the 4th die body 4 is provided with lower die lip 6.

First flow 81 is provided with between described first die body 1 and the second die body 2, first flow 81 afterbody is communicated with the first charging aperture 811, the second runner 82 is provided with between second die body 2 and the 3rd die body 3, second runner 82 tail end is communicated with the second charging aperture 821, be provided with the 3rd runner the 83, three runner 83 tail end between 3rd die body 3 and the 4th die body 4 and be communicated with the 3rd charging aperture 831.

The second discharging opening the 92, three runner 83 that the first discharging opening 91, second runner 82 that described first flow 81 flows through die lip 5 and core rod 7 upper surface composition flows through core rod 7 inside flows through the 3rd discharging opening 93 of core rod 7 lower surface and lower die lip 6 composition.

As shown in Figure 3, the front end of described second discharging opening 92 is multiple aperture 921 structures, and core rod 7 front end die core front end is provided with the guide groove 71 of some connection first discharging openings 91 and the 3rd discharging opening 93, and adjacent channels 71 separately single or multiple aperture 921 is arranged.Just be provided with a guide groove 71 at interval of an aperture 921 in the present embodiment, multiple aperture 921 separately can be arranged in practice as required.
