Building foundation pile cap forming die

The invention relates to the technical field of building foundation pile cap forming molds, in particular to a building foundation pile cap forming mold which comprises a foundation pile body, and the foundation pile body is connected with a cushion layer and a soil layer in a matched mode. A forming mechanism is fixedly mounted on the cushion layer; a mounting mechanism is fixed to the forming mechanism in a matched mode. A limiting block is clamped on the mounting mechanism; a driving mechanism is rotationally arranged on the limiting block; a limiting mechanism is mounted on the driving mechanism; the limiting mechanism is connected with the mounting mechanism in a matched mode. After the mounting mechanism is assembled, the limiting block can be clamped on the mounting mechanism, so that the limiting block drives the forming mechanism to be assembled together; the driving mechanism is rotated to drive the limiting mechanism to slide in the limiting block, so that the mounting mechanism is positioned; and
