高压电气产品铝合金机构室简易金属型铸造模具的研究

Study on simple metal casting mold for aluminum alloy mechanism chamber of high voltage electrical products

采用树脂砂砂型低压铸造方式生产的机构室类铸件,操作繁琐,劳动强度高,生产成本高,生产效率低,铸件外观和内在质量不尽如人意,废砂排放量大。研制了机构室简易金属型模具,以满足批量生产的要求,该简易金属型铸造模具采用整体式设计,顶冒口、边冒口及浇注系统预制成型。采用该简易金属型铸造模具生产铝合金机构室,操作简单,劳动强度低;铸件外表美观、内部组织致密无缺陷、成本低、生产效率高而且节能环保。

The aluminum alloy mechanism chamber has been produced by use of simple metal casting mold, which is easy to operate and low in labor intensity. The castings are of good quality and beautiful appearance, while the internal structure is dense and defect-free. The cost is low and the production efficiency is high with energy saving and environmental protection.
