Vortex external-mixing type double-medium atomizing nozzle for die spraying

Abstract

The invention relates to a vortex external-mixing type double-medium atomizing nozzle for die spraying. The vortex external-mixing type double-medium atomizing nozzle for die spraying comprises a valve seat, a valve body, an atomizing body, a nozzle cover and a locking cap, wherein a valve element is arranged at one end of the valve body; the atomizing body is arranged on the outer side of the valve element in a covering way and tightly presses the valve body; the locking cap is arranged at one end, far away from the valve body, of the atomizing body through screw threads in a sleeving way; aninstallation bin for installing the nozzle cover is formed between the inner peripheral face of the locking cap and the outer peripheral face of the atomizing body; one end, facing the valve body andbeing far away from the atomizing body, of the valve seat tightly presses the valve body; a release agent plug, a main gas circuit plug and multiple groups of branch gas circuit plugs are arranged onthe valve seat; a main gas pipeline, two groups of primary gas branch circuits and four groups of primary gas branch circuits communicating sequentially are arranged in the valve seat; the four groups of primary gas branch circuits respectively communicate with four groups of first grooves; a release agent pipeline is arranged in the valve seat; and the release agent pipeline, a second groove andthe valve element sequentially communicate. The vortex external-mixing type double-medium atomizing nozzle for die spraying provided by the invention can spray atomized particles with good particle size, so that the appearance defect rate of sprayed products is greatly reduced, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of nozzles, in particular to a vortex external mixing double-medium atomizing nozzle for mold spraying. Background technique [0002] The structure of the existing mold spraying external mixing dual-medium (liquid and gas) atomizing nozzle consists of a valve body, a piston, a spring, a spring pressing plate, an intermediate liquid pipe, a spherical nozzle atomizing head, a spherical nozzle atomizing head pressing plate, a sealing When in use, the liquid enters from the liquid flow path at the bottom of the valve body, passes through the liquid pipe, and then flows into the liquid flow path of the materialized nozzle of the nozzle and flows out. The atomizing gas enters through the atomizing gas flow path of the valve body, passes through the gas storage chamber, and flows out of the gas flow path of the materialized nozzle of the nozzle. The two media are realized and mixed in the cavity at the front end of...

Problems solved by technology

The atomizing gas enters through the atomizing gas flow path of the valve body, passes through the gas storage chamber, and flows out of the gas flow path of the materialized nozzle of the nozzle. The two media are realized and mixed in the cavity at the front end of the nozzle atomizing head to form atomization; but now Some mold spraying and external mixing dual-medium (liquid and gas) atomizing nozzles have uneven particle size, and the appearance of the product after spraying has a high failure rate, which requires reprocessing, which greatly reduces production efficiency; in addition, when disassembling The spraying point is easy to change, and it is impossible to quickly and accurately align the previous spraying point after decomposition, thereby increasing the rate of defective products; it needs to stop production and take time for debugging, which wastes manpower and reduces production efficiency; therefore, this application proposes a vortex for mold spraying.
