Die casting machine sprayer definition is a device to spray the mold release agent on mould inner cavity during die casting process.
Die casting machine sprayer function is by spraying the mold release agent to reduce the adhesion between the casting and the mold. To improve the demoulding efficiency and quality of the casting, and also improve the surface finish of the casting and reduce defects such as internal pores.
The working principle of die casting machine sprayer includes the following parts:
Die casting machine sprayer manipulator
The die casting machine sprayer manipulator is the core part of the spraying system. It realizes uniform spraying of the inner cavity of the mold through process actions such as mechanical arm extension, blowing, spraying, and blowing.
These manipulators can be connecting rod type or upright type. With the characteristics of structural optimization, high degree of automation, and high spraying efficiency.
Spraying application technology
Die casting machine spraying technology includes pulse spraying and continuous spraying. Among it pulse spraying technology can effectively control the temperature gradient on the mold surface, reduce the generation of thermal stress, and increase the life of the mold. At the same time, it reduces the use of release agent and improves the surface quality of the casting.
There is also an application based on in-mold spraying technology. This technology uses the spray pipe and atomizer designed inside the mold to achieve synchronous action with the spray manipulator on the die-casting machine, which greatly reduces the scrap rate of castings.
Innovative design
In order to improve the efficiency and quality of spraying, the design of spraying device is constantly innovating. The new vertical axis spraying device developed by some companies use belt drive instead of traditional rack and pinion drive to improve the performance limit of the device.
Moreover, there are semi-automatic die-casting equipment based on sprayer/mold integration, which aims to reduce production cycle and spray agent consumption and improve product quality.
Die casitng machine sprayer control and optimization
Control and optimization of spraying rocess is the key to improving spraying efficiency and quality. By adopting advanced control systems, such as hydraulic servo control systems, precise control of spraying manipulators can be achieved, thereby improving the response performance and stability of the system.
In addition, by optimizing spraying process parameters, such as spraying pressure, blowing pressure, atomization pressure, etc., the stability of casting surface quality can be further improved.
