Furthermore, in above-mentioned technical proposal, the principle between the steel mouth core and beryllium copper mouth core by expanding with heat and contract with cold It is assembled together.

Furthermore, in above-mentioned technical proposal, the hot mouth body periphery, which is formed, installs for the fever circle and is in Spiral helicine mounting groove, the fever circle are fixed in the mounting groove.

Furthermore, in above-mentioned technical proposal, the hot mouth body periphery is also arranged with a hot mouth locating ring, the hot mouth Locating ring periphery forms positioning pin.

Furthermore, in above-mentioned technical proposal, cast gate department upper end has thread segment, and the cast gate department passes through the spiral shell Line section is fixed with the hot mouth body lower end.

After adopting the above technical scheme, the utility model has the advantages that compared with prior art：This practicality Mouth core group in new is by steel mouth core and is fixedly sheathed in the beryllium copper mouth core of steel mouth core periphery and forms, and uses the steel of steel Mouth core is flowed through for plastic material, and the steel mouth core has good wear resistance, even if containing stronger abrasiveness plastic material When flowing through steel mouth core, which will not be worn, and to be conducive to improve product competitiveness in the market, and beryllium copper mouth core sets steel Mouth core periphery, with excellent thermal conductivity, that is to say, that the mouth core group has excellent thermal conductivity and good wear-resistant Property, make the utility model that there is the extremely strong market competitiveness.

Fig. 3 is the three-dimensional exploded view of the utility model.

Specific embodiment：

The utility model is further illustrated with reference to specific embodiments and the drawings.

It is a kind of hot mouth structure with copper clad steel mouth core as shown in Fig. 1-3, including：Hot mouth body 1 is wound in hot mouth The fever of 1 periphery of body encloses 2, is arranged in the mouth core group 3 of 1 lower end of hot mouth body and is installed on 1 lower end of hot mouth body and will Mouth core group 3 is packaged in the cast gate department 4 in hot mouth body 1.

The mouth core group 3 includes steel mouth core 31 and is fixedly sheathed in the beryllium copper mouth core 32 of 31 periphery of steel mouth core, should The sharp mouth of 31 lower end of steel mouth core is stretched out in outside 32 lower end of beryllium copper mouth core, and the sharp mouth of 31 lower end of steel mouth core also extends through cast gate department 4 and stretches Outside for 4 lower end of cast gate department, since mouth core group 3 by steel mouth core 31 and is fixedly sheathed in the peripheral beryllium copper mouth core of steel mouth core 31 32 are formed, and the steel mouth core 31 of steel is used to be flowed through for plastic material, and the steel mouth core 31 has good wear resistance, even if When flowing through steel mouth core 31 containing stronger abrasiveness plastic material, which will not be worn, to be conducive to improve production The product market competitiveness, and beryllium copper mouth core 32 sets 31 periphery of steel mouth core, with excellent thermal conductivity, that is to say, that the mouth core Module 3 has excellent thermal conductivity and good wear resistance, and the utility model is made to have the extremely strong market competitiveness.

It is assembled together between the steel mouth core 31 and beryllium copper mouth core 32 by the principle expanded with heat and contract with cold, specifically, first The beryllium copper mouth core 32 is heated to beryllium copper mouth core 32 to expand, and then steel mouth core 31 is plugged in the beryllium copper mouth core 32, Ran Houzai Beryllium copper mouth core 32 is shunk by the type of cooling, is assembled together so that steel mouth core 31 is caused to stablize with beryllium copper mouth core 32, structure Extremely stablize, ensure the stability of the utility model structure.

1 periphery of hot mouth body is formed encloses 2 installations and spiral mounting groove 11, the fever for the fever Circle 2 is fixed in the mounting groove 11.1 periphery of hot mouth body is also arranged with a hot mouth locating ring 5, outside the hot mouth locating ring 5 It encloses and forms positioning pin 51.4 upper end of cast gate department have thread segment 41, and the cast gate department 4 by the thread segment 41 with it is described 1 lower end of hot mouth body is fixed.
