| titleOfInvention | Casting device and process for large 90-degree pressure-resistant aluminum alloy bend shell of extra-high pressure GIS switching equipment |
| abstract | The invention relates to a casting device and process for a large 90-degree pressure-resistant aluminum alloy bend shell of extra-high pressure GIS switching equipment. The bend shell is of a 90-degree bend structure, flanges are arranged at the two ends of the bend shell, and the bend shell comprises a sand core lifting structure and a core box. The sand core lifting structure comprises a lifting hook, an embedded support connected with the lifting hook and a thick nut connected with the lifting hook and the embedded support. The core box is provided with a containing groove for containing a sand core, a notch for containing the lifting hook and a through hole allowing the containing groove and the notch to be communicated. The lower end of the embedded support of the sand core lifting structure is of a cross-shaped structure for locating two flange parts of the sand core respectively. The exact center of the upper portion between the two flanges of the sand core is located through the lifting hooks. An inner casting channel of the sand core comprises multiple vertical barrels connected with transverse casting channels and casting gates. By the adoption of the device and process, part casting quality can be improved, and it is guaranteed that parts receive the pressure of the hydraulic pressure destructive test requirement. |
