The tip 2 is a steel tip, the tip 2 is integrally formed at the other end of the beryllium copper core column 1, and in a specific application example, the tip 2 can be integrally formed at the other end of the beryllium copper core column 1 in a 3D printing mode.

In the above example, the whole open nozzle core is of an integrally formed structure, only one part is needed, and the processing procedures are reduced. In addition, the steel tip 2 and the beryllium copper core column 1 are firmly fused, so that the tip is not easy to wear, the beryllium copper core column 1 is integrally formed, the heat conduction effect is good, the service life is long, and the stability is better. In addition, the open type nozzle core is of an integrated structure, so that glue is not easy to leak in the process of sealing glue, a product gate is attractive, a product is not drawn, and the maintenance cost is low.

As shown in fig. 2, the center line a of the glue hole 101 intersects with the center line b of the beryllium copper core column 1, and an included angle is formed between the two, so that the glue hole 101 is an inclined hole, and the glue pressure can be buffered.

The outer diameter of the polish rod section 12 is greater than the outer diameter of the threaded section 13 and the outer diameter of the tail section 14, the threaded section 13 having the external threads 130 described above.

Wherein, because the external diameter of the tail section 14 is smaller than the external diameter of the thread section 13, when the thread section 13 is connected with the external hot nozzle body 3, the tail section 14 with smaller external diameter is inserted into the hot nozzle body 3 first, so that the tail section 14 has the guiding effect for the thread section 13.

Preferably, the side of the tail section 14 facing away from the thread section 13 is provided with a guiding inclined surface 140, and the guiding inclined surface 140 is used for guiding the tail section 14 inserted into the nozzle body 3. In this example, the guiding of the tail section 14 to the thread section 13 is facilitated by the provision of the guiding ramp 140.
