They were originally used for die-casting type. With the progress of science and technology and industrial production, especially with the development of industries such as automobiles, motorcycles and household appliances, and from the perspective of energy conservation and saving raw materials, die-casting technology has achieved extremely rapid development. A sprayer is a machine that disperses liquid into mist. The uses of a sprayer are: (1) Uniform spraying of release agent; (2) Rapid cooling of the mold; (3) Cleaning the mold surface; (4) Providing stable and fast production efficiency. Classification of spray robots: hot chamber die-casting machine; upright sprayer; cold chamber die-casting machine; servo sprayer;

[0003] However, when the die-casting machine is working, it is necessary to use a sprayer to spray a mold release agent for the next working cycle. However, some mold structures are relatively complex, and the spraying effect of the sprayer moving up and down is not good, and there is an uneven spraying of the release agent. For example, the patent with application number CN201520636712.2 discloses a connecting rod sprayer, which relates to the technical field of sprayers, including a support, a fixed arm, a sprayer, a control device, a hydraulic cylinder, a fixed seat, a slide rod, a fixed block, a spray head and a buffer spring.
