Technical Field
The utility model relates to a wind generating set blade mould structure and the technical field of water conservancy diversion system especially indicate a wind-powered electricity generation blade casing irritates forming die fast.
Background
At present, the traditional method for manufacturing the blade shell is to lay a structural cloth layer, a main beam, a core material and the like on the surfaces of a SS surface die and a PS surface die of a blade respectively, and then place an auxiliary flow guide material on the surface of the structural layer after the structural layer is completely laid. Then, a vacuum pumping maintenance system was prepared, and finally, the resin was introduced. Thus, the resin is sequentially pushed to be poured and molded on the surface of the structural layer in the width (chord direction) and length (axial direction) directions from the surface to the bottom surface in the thickness direction through the surface flow guide material. The disadvantage is that the blade shell resin introduction moulding process takes a relatively long time. The resin is introduced into the product structure layer and is soaked through a conventional guide pipe, and one resin is sequentially analogized from one side to the other side. Usually, to save time, the central feed tube is opened and resin is advanced from the center of the product to both the leading and trailing edges. However, the whole process time is longer due to the larger surface of the product, and the gel time requirement for the resin is higher. Another disadvantage is that the flow is directed in the direction of the thickness of the product, from the top surface to the bottom surface of the product. If the surface resin is guided too fast, the bottom resin is supplied and soaked slowly and the flow rate of the surface resin is asynchronous, so that the bottom resin of the product is lack or the bottom resin is partially surrounded, and the major defect of the product is caused. After the pouring is finished, whether the pouring quality of the bottom surface of the product is good or not is not determined, so that the technological process is difficult to control, and more influencing factors exist.

Furthermore, the lower surface of the draft tube is formed into a shape adapting to the diversion trench, the upper surface of the draft tube is formed into an arc-shaped surface adapting to the arc-shaped profile, and the arc-shaped surface of the longitudinal draft tube is flush with the arc-shaped profile.
Compared with the prior art, the utility model, have following advantage and beneficial effect:
1. the utility model discloses a mould passes through the design of guiding gutter and water conservancy diversion pipe network, with current from the product surface to the bottom surface, from the middle resin water conservancy diversion mode to both sides of product, become from the shaping mode on mould surface (product bottom surface promptly) to the product surface, make the resin leading-in efficient, realize optimization, the quick shaping of mould, very big when having practiced thrift the shaping, practice thrift out product efficiency.
2. The utility model discloses a mould provides stable water conservancy diversion drainage channel through the design of water conservancy diversion pipe network, avoids product bottom surface resin to surround the risk, has reduced the filling time, reduces and fills the risk, has promoted product quality.
