Self-adaptive deformation preforming mold

The utility model discloses a self-adaptive deformation preforming mold, and belongs to the technical field of box body pavement. The self-adaptive deformation pre-forming mold comprises a first mold plate; the plurality of groups of second templates are symmetrically connected to the first template; the sliding rod is fixedly connected to the first template; the sliding plate is slidably connected to the sliding rod; the connecting arm is rotationally connected to the sliding plate, and the end, away from the sliding plate, of the connecting arm is rotationally connected with the second template; according to the device, the pre-forming mold is integrally decomposed, the second mold plates on the side faces are unfolded, the second mold plates on the side faces and the first mold plates on the top face are located on the same plane, and in the paving process, paving of the side faces of the box body is reduced, so that the paving difficulty is reduced, and meanwhile the paving efficiency is improved. 本实用新型公开
