The technical solution of the utility model is: a kind of flow distribution plate for plastic extruder, including shunting plate body, described shunting plate body is stacked by four pieces of identical shunting layer flaggies, the diffluence pass relative to shunting laminate end slope is all had every piece of shunting laminate upper edge, the diffluence pass of four blocks of shunting laminates is the most corresponding, and the mutual spiral in head piece side of diffluence pass is spliced into splitter box, it is provided with through hole in the centre of shunting plate body, it is provided with heating member between 2 shunting laminates of the close top layer of shunting plate body, in the region that each heating member is encircled a city, it is provided with two overflowings portal, overfolw hole is located on the shunting laminate upper surface of top layer,
Described overfolw hole runs through four blocks of shunting laminates, described shunting plate body is provided with flow channel component, flow channel component includes first passage, second channel, first row overfolw hole near through-hole side connects the top of first passage, second row overfolw hole connects the top of second channel, first passage, the lower end of second channel is connected by horizontal cavity, described horizontal cavity is connected with nozzle by perpendicular cavity, described nozzle is located at the shunting laminate surface of the bottom of shunting plate body, described first passage, it is connected with inclined flow passage by X shape runner respectively between second channel.
Further, the first diffluence pass and second diffluence pass at described splitter box two ends are shunting the end on projection of plate body without overlapping.
Further, it is arranged with heating member between 2 described shunting laminates.
Further, described heating member includes heat conductive filament, and the two ends of heat conductive filament are connected with two poles.
Further, the groove depth of described splitter box gradually becomes shallower as.
This utility model has the advantage that with good effect: owing to using technique scheme, at circulation assembly, the splitter box of the setting of flow distribution plate mountain, it is ensured that plastic splitter effect in the molten state is more preferable, convenient；The phenomenon blocked and its automatically provide heating function effectively to prevent flow distribution plate from occurring, have simple in construction, easy to maintenance, the advantages such as processing cost is low.

Detailed description of the invention
As Figure 1-3, the technical solution of the utility model is: a kind of flow distribution plate for plastic extruder, including shunting plate body 1, described shunting plate body 1 is stacked together by four blocks of identical shunting laminates 2, the diffluence pass relative to shunting laminate 2 end slope is all had every piece of shunting laminate 2 upper edge, the diffluence pass of four blocks of shunting laminates 2 is the most corresponding, and the mutual spiral in head piece side of diffluence pass is spliced into splitter box 3, it is provided with through hole 4 in the centre of shunting plate body 1, it is used for connecting screw rod at this through hole 4 to use, it is provided with heating member 5 between 2 shunting laminates 2 of the close top layer of shunting plate body 1, in the region in each heating member 5 besieged city, it is provided with two overflowings portal, overfolw hole is located on shunting laminate 2 upper surface of top layer,
Described overfolw hole 6 runs through four blocks of shunting laminates 3, described shunting plate body 1 is provided with flow channel component, flow channel component includes first passage 7, second channel 8, first row overfolw hole 6 near through hole 4 side connects the top of first passage 7, second row overfolw hole 9 connects the top of second channel 8, first passage 7, the lower end of second channel 8 is connected by horizontal cavity 10, described horizontal cavity 10 is connected with nozzle 12 by perpendicular cavity 11, described nozzle 12 is located at shunting laminate 2 surface of the bottom of shunting plate body 1, described first passage 7, it is connected with inclined flow passage 14 by X shape runner 13 respectively between second channel 8.
