Bent pipe core-pulling structure

The utility model discloses a core-pulling structure for a bent pipe, which belongs to the technical field of side-pulling structures of injection molds and comprises a power mechanism, a rack structure, a tooth block structure, a rotating shaft, a rotating bearing, a check block, two sliding blocks and two guide pressing blocks. The power mechanism serves as a driving mechanism of the rack structure, enables the rack structure to move along a straight line and drives the tooth block structure to further enable the tooth block structure to rotate around the rotating shaft. A rotating bearing is arranged at the joint of the rotating shaft and the tooth block structure, so that rotation of the tooth block structure is facilitated, and the torque of the tooth block structure is further enhanced; the stop block is connected with an external mold structure and is connected to the end part of the rotating shaft; the two sliding blocks are movably connected with the corresponding guide pressing blocks respectively,
