Producing technique and producing die of syringe rubber stopper

Abstract

The present invention provides a producing technique and a producing die of a syringe rubber stopper, belonging to the technical field of medical apparatuses. The present invention solves the problems that the existing producing technique of a syringe rubber stopper is complicated and the existing producing die of a syringe rubber stopper is complicated in structure. The rubber stopper produced by the producing technique of a syringe rubber stopper is cylindrical. The producing technique comprises the following steps of loading materials, molding and obtaining finished products. The die of a syringe rubber stopper comprises a concave die and a convex die which can be mutually buckled. The concave die is provided with a cylindrical cavity, the center of the bottom of the cylindrical cavityis provided with an inner rod axially projected, and the center of the convex die is provided with an inserting rod axially projected. When the concave die and the convex die are buckled, the inserting rod is inserted in the cylindrical cavity, and the inserting rod is coaxially arranged with the inner rod. The present invention has the advantages of simple processing procedure, easy operation, high work efficiency, capability of effectively removing flashes, convenient processing, reasonable structure design, etc.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a production process of a syringe rubber stopper and a production mold of the syringe rubber stopper. Background technique [0002] Syringe is a tool commonly used by people in the treatment of diseases. It provides a very convenient way for drugs to enter the body smoothly. At the same time, it also has the advantages of low cost, high safety and simple manufacturing process, so it is widely used by people. In order to avoid the cross-infection of viruses caused by the use of unhygienic syringes, disposable syringes have been widely used in the field of medical technology. At present, there are many kinds of self-destructing and safety syringes, but they are all inconvenient to use. When the needle protection cover is put back on the needle after the injection, it is easy to pierce the medical staff, thus causing germs to endanger the medical staff. Moreover, in the proce...

AI Technical Summary

Problems solved by technology

It mainly also has the following disadvantages: the produced syringe rubber stopper will inevitably produce flashes and burrs, and the flashes and burrs will enter the human body with the infusion liquid during use, causing serious negative effects on the human body; The device of the plug is too complicated, and has problems such as inconvenient operation and complicated processing procedures; moreover, the rubber plugs in the prior art are not symmetrical in structure, and the rubber plug must be assembled on the injection rod in an orientation during the process of assembling the syringe, and manual labor is required. Assembly, its production cost is high and production efficiency is low
