[0012] Beneficial Effects
[0013] Compared with the prior art, the advantages of the diverter plate of the extrusion die head of the utility model are:
[0014] 1. When the material enters the main body of the diverter plate from the feed port, at least two diverter channels are separated by the diverter structure. The material is discharged from the discharge port of the diverter channel and enters the subsequent channel, thereby realizing simultaneous discharge of multiple angle lines without increasing the number of material melting and conveying equipment and molds, thereby improving production efficiency, and the production cost is not significantly increased, the production cost is low, and the footprint is small.
[0015] 2. The material entering from the feed port is cut by the first material dividing blade, and the structure is simple.
[0016] 3. The discharge port is in the shape of a figure 7, which is suitable for corner lines. At this time, part of the material entering the diversion channel is separated to the left and right by the second material dividing blade, and the material is guided by the inner edge front guide surface, the inner edge rear guide surface, the outer edge front guide surface, the outer edge rear guide surface, and the transition guide surface to ensure that the flow of the material is uniform at each location when the material passes through the figure 7 discharge port, thereby ensuring that the corner line has a high dimensional accuracy after forming and the strength is basically consistent at each location.
[0017] 4. When at least two feed ports are provided on the main body of the diverter plate and arranged in sequence, the material flow rate in the middle is faster than that of the outermost parts on the left and right ends. The second outer edge front guide surface and the outer edge rear guide surface behind it are coplanar, which can ensure that the material there has a higher flow rate. The front end edge of the first outer edge front guide surface is arc-shaped and smoothly transitions with the rest of the front end edge of the diverter channel, which can avoid the problem of material accumulation here due to too low flow rate.
