Spraying device and spraying machine

Abstract

The invention discloses a spraying device and a spraying machine. The spraying device comprises a valve seat and a spraying head; an air feeding channel and a water feeding channel are formed in the valve seat; the spraying head is arranged on the valve seat and comprises a connecting end arranged on the valve seat and a spraying end opposite to the connecting end; an inner channel and an outer annular channel annularly formed in the periphery of the inner channel are formed in the spraying head; one of the inner channel and the outer annular channel communicates with the air feeding channel,and the other one of the inner channel and the outer annular channel communicates with the water feeding channel; and at the spraying end, the inner channel and the outer annular channel are adjacently formed, and thus water and air which flow out of the inner channel and the outer annular channel are joined outside the valve seat to be atomized. The risk that the water and the air are mixed in the valve seat, an air flow or a water flow enters different cavities, and consequently the atomization effect is poor is lowered, thus the spraying device has the good atomization effect, and the cooling effect is improved.

Description

technical field [0001] The invention relates to the technical field of mold processing and production equipment, in particular to a spray device and a spray machine. Background technique [0002] In the process of mold processing and production, many molded products need high temperature (such as injection mold, die-casting mold, etc.), so the mold needs to be cooled before forming the product. The existing cooling process usually uses a water gun to spray water on the mold manually. There are many disadvantages in the way of cooling the mold by spraying water, for example, there will be water splashing, the atomization effect is not good, resulting in poor cooling effect and so on. Contents of the invention [0003] The main purpose of the present invention is to propose a spray device and a spray machine, aiming at optimizing the cooling method, improving the atomization effect, and further improving the cooling effect. [0004] To achieve the above object, the present ...
