| Abstract: | In order to realize green foundry, according to the structural characteristics of the gearbox of the loader and the existing production conditions of the enterprise, the expendable casting process(EPC) and production flow of the gearbox of the loader were designed. The production shows that the foaming mould can be used for sheet forming, bonding, drying and pouring in an inclined way. Control of pouring temperature is 1 470 ±5 ℃, pouring negative pressure is 0.05 MPa,negative pressure time is 3 min, it can be obtained with high dimensional accuracy, surface without flash burr, no casting defects of castings. |
