Automatic bending deformation correction mechanism

The automatic bending deformation correcting mechanism comprises a fixed base, correcting grooves are formed in the two sides of the middle of the upper end of a push-out bottom plate, pressing rods are slidably connected to the middles of the correcting grooves, and first push-out rods penetrate through and are slidably connected to the middles of the upper ends of first grooves; second push-out rods penetrate through the middles of the upper ends of the second grooves and are slidably connected with the middles of the upper ends of the second grooves, and second push blocks are fixedly connected to the bottom ends of the second push-out rods. According to the utility model, the first push block is driven by the push-out bottom plate to enable the first push-out rod to move upwards together, so that the middle part of a plastic part is upwards bulged out of a mold cavity, and when the push-out bottom plate moves upwards, the pressing block is jacked by the second push block to move downwards by a set clearan
