Liquid volume quantifying device

Abstract

The invention provides a liquid volume quantifying device which comprises a first base, a quantifying cylinder, a piston and a second base, the quantifying cylinder is provided with a first end and a second end, the first end of the quantifying cylinder is arranged on the first base, and the second end of the quantifying cylinder is arranged on the second base; a liquid inlet and a liquid outlet are formed in the first base, and the liquid inlet and the liquid outlet are communicated to form a fluid channel communicated with the interior of the quantitative cylinder; a liquid inlet valve is arranged at the liquid inlet, and a liquid outlet valve is arranged at the liquid outlet; the periphery of the piston is in close contact with the inner wall of the quantitative cylinder; and a reset device for driving the piston to move to the minimum stroke position is arranged on the second base. According to the invention, the maximum stroke position and the minimum stroke position of the piston are utilized to realize quantitative discharge of the stock solution, and the quantitative accuracy is ensured.

Description

technical field [0001] The invention belongs to the technical field of release agent configuration, and in particular relates to a liquid volume quantification device. Background technique [0002] With the rapid development of vehicle lightweighting and 5G communication, the structure of die-casting products such as body structural parts, new energy parts, and 5G communication parts is becoming more and more complex, and the requirements for die-casting equipment are higher. In the production process of die-casting products, the demolding quality of die-casting products directly affects the qualification rate of die-casting products, and the demolding quality of die-casting products is largely affected by the release agent, especially the concentration of the release agent. A low concentration of release agent will cause the die-casting product to be unable to be released smoothly, while a high concentration will lead to the accumulation of paint on the surface of the produ...

AI Technical Summary

Problems solved by technology

A low concentration of release agent will cause the die-casting product to be unable to be demolded smoothly, and a high concentration will cause the accumulation of paint on the surface of the product to produce mottled colors, and it will also cause waste of release agent, which will increase the cost

Therefore, in order to realize the precise proportioning of the release agent, it is necessary to accurately quantify the stock solution and water. However, the existing quantitative device is usually a measuring cup. When the stock solution is poured into water for mixing, part of the stock solution will remain in the measuring cup, making the concentration of the mixture low; even if a sensor such as a flow meter is used for quantification, the delay of the sensor will cause excess stock solution, resulting in a high concentration of the mixture , cannot achieve the purpose of precise quantification,
