specific Embodiment approach 1
[0017] Specific implementation mode 1: In this embodiment, the anti-gravity casting riser pipe positioning mechanism is set up in sequence from top to bottom with the mold 1, the upper sealing gasket 4 of the riser pipe, the positioning ring 5, the middle partition plate 6, the positioning bolt 7, and the riser pipe The lower sealing gasket 8 and the riser pipe 9, the riser pipe 9 is fixed on the intermediate partition 6 by the positioning ring 5 and the positioning bolt 7, the upper end of the riser pipe 9 is provided with a flange 9-1, and the flange 9-1 The side surface is provided with a hoisting port 9-2, the top of the flange 9-1 is provided with a limit groove 9-3, the sealing gasket 4 on the riser pipe is matched with the limit groove 9-3, and the upper part of the positioning ring 5 is a conical platform, positioning The lower section of the ring 5 is a cylindrical platform, and a hoisting hole 5-1 is provided on the side of the conical platform. The cavity 2 is locate...
specific Embodiment approach 2
[0018] Embodiment 2: This embodiment differs from Embodiment 1 in that the positioning ring 5 is provided with a central stepped hole 5-4, and the flange 9-1 cooperates with the central stepped hole 5-4. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0019] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that there are four positioning slots 5-2 and positioning bolt inlet and outlet 5-3 under the cylindrical platform, and the positioning slots 5- 2 communicate with the set bolt inlet and outlet 5-3.
