Problems solved by technology

[0002] In the prior art, the injection nozzle assembly adopts a spring heater and a stainless steel jacket structure. Because the spring heater is not strong enough, it is easy to deform, and it is not closely matched with the injection nozzle body. The temperature is unstable during heating, and the spring heater is easy to accumulate heat and damage. Maintenance Too many maintenance times and low production efficiency
Not suitable for mass production

Abstract

The invention discloses an injection nozzle assembly, which comprises an injection nozzle main body, wherein the injection nozzle main body is arranged in a cylindrical shape, a through hole is arranged inside the injection nozzle main body, a heating steel sleeve is sleeved on the outer circumference of the injection nozzle main body, and is fixed on the injection nozzle main body by a metal snapping hoop, the outer circumference of the injection nozzle end of the injection nozzle main body is provided with a snapping spring for snapping the end portion of the heating steel sleeve, and the outer circumference of the other end of the injection nozzle main body is provided with a fastening hexagon nut. According to the present invention, the injection nozzle assembly has characteristics ofrapid heating, high heat energy conversion efficiency, balanced heating, energy saving, environmental protection, long service life and low cost.

Description

technical field [0001] The invention relates to an improvement of an injection nozzle assembly, in particular to an injection nozzle assembly with fast heating speed, high thermal energy conversion efficiency, balanced heating, energy saving and environmental protection, long service life and low cost. Background technique [0002] In the prior art, the injection nozzle assembly adopts the structure of a spring heater and a stainless steel jacket. Due to the insufficient strength of the spring heater, it is easy to deform, and it does not fit closely with the main body of the injection nozzle. The temperature is unstable during heating, and the spring heater is easily damaged by heat accumulation. Many maintenance times and low production efficiency. Not suitable for mass production. [0003] For this reason, we have developed a nozzle assembly with fast heating speed, high thermal energy conversion efficiency, balanced heating, energy saving and environmental protection, l...
