Core mold demolding mechanism

A circular ring and a ring pipe of a product to be formed share the same core and are arranged at intervals, a connecting arm parallel to the axial direction is arranged between the circular ring and the ring pipe, a core mold comprises a circular ring inner end face core mold used for forming the inner side end face of the circular ring, and a space core mold is arranged between the circular ring inner end face core mold and the ring pipe. The demolding displacement direction of the airspace core mold is perpendicular to the parting surface of the lower mold and the upper mold, and the demolding displacement direction of the circular ring inner end face core mold is parallel to the parting surface of the upper mold and the lower mold and moves towards the side where the ring pipe is located. The problem that the forming core mold of the annular part of the upper pipe of the to-be-formed product cannot be directly demolded in the direction perpendicular to or parallel to the parting surface is solved. 本发明提供一种
