This utility model belongs to the technical field of mold clamping for electric extrusion blow molding machines, and in particular relates to a mold clamping transmission mechanism for an electric extrusion blow molding machine. It includes mutually hinged connecting rods, and the two hinged connecting rods are respectively connected to the inner and outer layers of a rolling bearing. A positioning ring is welded on the end face of the outer layer of the rolling bearing, a bushing sleeve is installed on the outer side of the positioning ring, the bushing sleeve wraps the outer layer of the rolling bearing, and the outer side of the bushing sleeve is sleeved in the connecting rod. The device adopts the bushing sleeve wrapping the outer layer of the rolling bearing to reduce the impact caused by mold clamping movement, and at the same time, the positioning ring welded on the outer layer of the rolling bearing ensures the lateral fixation of the rolling bearing after installation. It not only retains the operational advantages of the rolling bearing, but also reduces the impact on the rolling bearing, greatly prolonging its service life.
