[0002] Thick and large castings are important basic castings in the process of wind energy application, such as bases and hubs, etc., which have the characteristics of very large size, heavy weight, and high quality requirements. Riser, and the riser is generally lower than the bottom of the sprue cup of the pouring device, so the overflow of raw materials (molten iron) is easy to occur during the pouring process, causing pollution to the surrounding environment, and the process of cleaning and recycling these wastes It will also consume a lot of manpower and material resources in the process, and the production cost is high. In addition, the cooling of the casting during the pouring process requires feeding. Since the riser is lower than the sprue cup, the feeding is mainly completed through the gate. Therefore, the feeding process It is easy to mix impurities at the gate into the casting, affecting product quality

Embodiment Construction
[0016] Such as figure 1 As shown, a pouring device for thick and large wind energy castings includes a sprue cup 1, a casting mold 2 and a riser 3. Based on the direction of use, the sprue cup and the casting mold are connected through a pouring pipeline. The level of the bottom 12 of the sprue cup is higher than the level of the top 21 of the casting mold, and the riser is fixedly arranged on the top of the casting mold, and is connected with the casting mold. The level of the top 31 of the sprue cup is higher than the level of the bottom of the sprue cup, and lower than the level of the top 11 of the sprue cup, so that, with respect to the generally used riser, the riser of this case has been added It is high, and the size is reduced, and the number of risers used is also reduced, so it can save a lot of resources and reduce the production cost of the enterprise; the use of this increased riser can also store more pouring raw materials, avoiding the The pouring raw material...
