What is a syringe barrel mold?

The syringe barrel mold includes a fixed side pick-up plate, a movable side pick-up plate, a positioning ring and a sprue sleeve. It is characterized in that a circulating cooling water channel is arranged on the fixed side cavity plate. The movable side die-opening tie rod bolt is threadedly connected with the movable side die-opening tie rod, the movable side die-opening tie rod is movably installed in the hole of the movable side push plate, and the movable side limit tie rod bolt is used on the movable side take-out plate The movable side limit pull rod is threadedly connected, and the movable side limit pull rod is movably passed through the hole of the movable side push plate. The utility model produces a syringe barrel, the mold structure is simple, the circulating water cooling is balanced, the molding cycle is short, and the production efficiency is high.

The barrel structure of the disposable syringe includes a hollow barrel, and the inner wall of the proximal end of the hollow barrel is provided with an annular groove that cooperates with the upper limit step of the push rod. The convex ring forms the groove wall, wherein the height of the rear convex ring is greater than that of the front convex ring by 0.25mm-0.35mm. This product uses the height difference between the front and rear convex rings, so that the push rod is not easy to be pulled out without destroying the hollow cylinder after use, which ensures the safety of the "one-time" use of the syringe and is conducive to preventing cross-infection.
