[0006] The circumferential side surface is arranged perpendicular to the assembly casting surface and cooperates with the assembly casting surface to form a shell structure; the circumferential side surface includes a bottom surface, a side surface, an oblique side surface and a top side surface; the bottom surface, side surface, oblique side surface and top side surface are arranged corresponding to the bottom edge, side edge, oblique edge and top edge of the assembly casting surface respectively;

[0007] There are three clamping process blocks, which are correspondingly arranged on two side surfaces and a top side surface of the circumferential side surface; the clamping process blocks are distributed in a triangular shape on the outer contour of the shell structure.

[0008] Furthermore, the clamping process block is a rectangular parallelepiped structure, and the clamping process block is arranged close to the assembly casting surface.

[0009] Furthermore, the contour enclosed by the circumferential side surfaces is cast to form a parting surface on a side away from the assembly casting surface.

[0010] The advantages of the present invention are:

[0011] 1) In the utility model, a clamping process block is integrally cast on the outer contour of the square trough casting shell during casting, so that the clamping process blocks are distributed in a triangular shape; when the square trough casting shell is processed, a clamp is used to directly clamp the clamping process block structure; there is no need to clamp the thin-wall position of the square trough casting shell. This clamping method can effectively prevent the square trough shell from being deformed during the conventional clamping process and the problem of poor processing accuracy caused by multiple changes in the processing surface.
