Method for preventing drifting of riser bush

The invention belongs to the technical field of casting, and mainly relates to a casting method for preventing drifting of a riser bush, which comprises the following steps: manufacturing a casting sand core, and arranging the riser bush on the casting sand core; and a riser sleeve fixing device is manufactured, the riser sleeve fixing device comprises a supporting assembly and a pressing piece, the supporting assembly is connected with the casting sand core, the supporting assembly is connected with the pressing piece, and the pressing piece is used for fixing the riser sleeve. The dead head sleeve is fixed by adding the dead head sleeve fixing device, so that a dead head sleeve cover is replaced to press and fix the dead head sleeve in a bare casting mode, and the dead head sleeve is prevented from drifting. On one hand, production cost of the riser sleeve cover can be saved, on the other hand, process design is simplified, and production efficiency is improved. 本发明属于铸造技术领域，主要涉及一种防止冒口套漂移的铸造方法，包括以下步骤：制作铸件砂芯，
