Eddy current air inflow type nozzle for spraying release agent

Abstract

The invention discloses an eddy current air inflow type nozzle for spraying a release agent. The eddy current air inflow type nozzle is characterized in that the eddy current air inflow type nozzle comprises an atomization head and a movable iron core. The atomization head is arranged in a nozzle cap, the nozzle cap is connected with a front valve body through a thread, the atomization head is clamped between the nozzle cap and the front valve body, and the front section of the movable iron core is arranged in the atomization head; the middle section of the movable iron core penetrates throughthe front valve body, the rear section of the movable iron core is arranged in a guide sleeve, and a coil framework is arranged on the rear face of the guide sleeve; the coil framework is wound witha coil, the coil framework is arranged in a rear shell, and a static iron core is arranged in the coil framework; and the rear end of the static iron core is clamped between the coil framework and therear shell through a shaft shoulder, the rear section of the guide sleeve is further arranged in the coil framework, and an electromagnetic coil wiring outlet is formed in the bottom face of the rearshell. According to the eddy current air inflow type nozzle for spraying the release agent, the nozzle has good response time, the actual requirements can be met, the using amount of the release agent can be reduced, the economic benefits of enterprises are improved, and the pollution to the environment is greatly relieved.

Description

technical field [0001] The invention relates to a nozzle for vortex air-intake type release agent spraying, in particular to an electromagnetic nozzle which uses air and liquid (casting mold release agent) as the medium and realizes pulse spraying through electromagnetic control, which belongs to liquid atomization and electromagnetic control field. Background technique [0002] At present, for the mold of the casting machine, the water-soluble release agent is usually sprayed with 80-150 times diluted release agent, which is sprayed out by continuous spraying. A large amount of release agent is dropped and lost, and only a small amount of release agent is used. The agent remains on the mold. Cause the waste of release agent and the pollution to environment. The concept of gap or pulse spraying has been proposed internationally. With a certain ON / OFF control, this spraying method can be realized, which can greatly save the use of release agent, improve economic benefits, a...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a vortex air-intake type release agent spraying nozzle with good response time, improved economic benefit, and reduced environmental pollution, which solves the current problem of using solenoid valves to indirectly control the gas path or liquid of the nozzle. The circuit is switched on and off to realize the pulse spraying of the release agent, which leads to the problem that the response time of the nozzle opening and closing is too long, and the disturbance of the release agent liquid in the liquid channel is too large
