A mold clamping and locking mechanism of a stretch blow molding machine is an equipment component for producing plastic hollow containers. It is provided with a set of templates of the stretch blow molding machine, each template is connected in series by guide posts, the bottom of the templates is in contact with the guide rail of the stretch blow molding machine, a mold is installed in the templates and connected with a mold clamping cylinder. The rear wall of the middle template is simultaneously connected with a mold clamping piston rod and a mold locking cylinder, the mold clamping cylinder is mounted on the outer wall of the rear template, one end of the mold locking piston rod of the mold locking cylinder is connected with a piston, and the other end is formed with a bayonet. A mold locking block cylinder is mounted on the inner side of the rear template, the piston rod of the mold locking block cylinder is connected with a mold locking block, and a mold locking chute is formed in the mold locking block and matched with the mold locking piston rod and the bayonet. In the technical scheme, after the template connected with the mold is closed, the mold is further locked by the mold locking mechanism to avoid mold expansion and ensure the quality of processed plastic products.
