PMI (polymethacrylimide) foam board heat setting mold

A PMI foam board heat-setting mold relates to the technical field of heat-setting molds and comprises a fixed mold, supporting plates are symmetrically and fixedly mounted at the lower end of the fixed mold, a mold cavity is formed in the upper end of the fixed mold, an arc-shaped groove is formed in the inner wall of the mold cavity, a column groove is formed in the inner wall of the arc-shaped groove, a U-shaped plate is fixedly mounted at the upper end of the fixed mold, and first sliding grooves are symmetrically formed in the inner wall of the U-shaped plate. The clamping mechanism comprises fixing plates, the two fixing plates are fixedly connected with the fixed mold, second sliding grooves are formed in the inner walls of the two fixing plates, inner grooves are formed in the lower ends of the two fixing plates, threaded holes are formed in the inner walls of the two inner grooves, inner strips are movably installed in the two inner grooves, T-shaped grooves are symmetrically formed in the lower ends
