[0002] A blow molding machine is a machine that blows bottles. In its simplest terms, it's a machine that can blow plastic granules (softened into a liquid) or pre-made bottle preforms into bottles using specific processes. Blow molding machines are convenient, fast, and have a large production capacity, making them widely used by most companies.

[0003] The existing publication number CN210362421U discloses a mouthpiece kit, including a steel part, a sealing ring installed on the left side of the steel part, a bushing installed inside the steel part, an aluminum sleeve, a spring installed inside the aluminum sleeve, and a running shaft inserted in the middle of the spring. The steel part and the aluminum sleeve are threadedly connected. The left end of the aluminum sleeve has an installation groove, and the steel sleeve is installed in the installation groove. It can effectively reduce the risk of the inner wall of the aluminum sleeve being scratched during operation, play a safety protection role for the extension and retraction movement of the running shaft and the spring, and extend the service life of the mouthpiece kit.
