Abstract
The invention relates to an automatic releasing agent proportioning economizer for a die casting machine. The automatic releasing agent proportioning economizer is high in automation and control accuracy and comprises a liquid level sensor, a flow sensor, a pressure sensor, an electric energy transducer, a liquid level module, a flow module, a pressure module, an electric energy module, an original feedback system, a human machine interface (HMI) monitoring system, a communication module, an input interface, a central processing unit, a frequency transformer communication data interface, an output interface, a frequency transformer I, a frequency transformer II, a proportional valve and an external execution unit, wherein the flow sensor, the liquid level sensor and the pressure sensor are used for acquiring the flow of a raw material, the flow of water, a liquid level of a releasing agent dispensing pool and the pressure of a dispensing pump manifold in real time; the central processing unit is used for processing and regulating; and the execution unit is used for accurate execution. The automatic releasing agent proportioning economizer has the characteristics that: the raw material of a releasing agent is reduced, the production efficiency of the die casting machine is improved, electric energy is saved, pollution is reduced, automation of production management is realized,and impact on natural grid is reduced.
Description
technical field [0001] The invention relates to the automatic energy-saving control technology for the proportioning of the release agent and the delivery of ingredients, and an automatic energy-saving electric appliance. Background technique [0002] In the release agent batching and conveying system of the die-casting machine, the manual adjustment of the release agent ratio makes the release agent batching unable to meet the needs of various castings, which greatly affects the pass rate of the die-casting machine. At the same time, in order to meet the smooth release of castings, the amount of release agent raw materials will inevitably be artificially increased. Make it cause a lot of waste of raw materials and water. In addition, the release agent ingredient delivery pump is designed according to the maximum usage and the pressure requirements of the farthest equipment, but the operation of the equipment on site is changing all the time, and the required release agent ...
