A device for vacuuming molten metal

Abstract

The invention discloses vacuum molten metal taking equipment. The vacuum molten metal taking equipment comprises a displacement mechanism and a vacuum quantifying mechanism arranged on the displacement mechanism. The displacement mechanism is used for driving the vacuum quantifying mechanism to move in a three-dimensional space. The vacuum quantifying mechanism is used for taking molten liquid. A molten liquid pot is connected with a molten liquid taking position monitoring module, and the molten liquid taking position monitoring module can change the air pressure in the molten liquid pot and determine the molten liquid taking position by monitoring the air pressure in the molten liquid pot. The vacuum quantifying mechanism is connected with the displacement mechanism through a turnover mechanism, and the turnover mechanism can drive the vacuum quantifying mechanism to incline by a certain angle. A weighing sensor is arranged at the joint of the vacuum quantifying mechanism and the turnover mechanism. Due to the fact that the turnover mechanism can drive the vacuum quantifying mechanism to incline by a certain angle, the molten liquid pot can incline to be aligned with a die chamber of a die-casting machine in the molten liquid feeding process, the stability of butt joint of the molten liquid pot and the die chamber of the die-casting machine is improved, and leakage of molten liquid is avoided.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to a device for vacuuming molten metal. Background technique [0002] At present, in various die-casting industries, the method of ladle soup is commonly used to give soup. This method of taking soup has the disadvantages that the molten metal is easily oxidized, the low-quality soup on the surface is easy to be scooped, and the precision of the soup is low. , The initial setting of the amount of soup is complicated and other disadvantages. On the other hand, because the height of the molten metal in the furnace is often changed, and the height of the molten metal is difficult to detect, the height of the molten metal cannot be determined, and the molten metal cannot be drawn quantitatively.

[0002] At present, in various die-casting industries, the method of ladle soup is commonly used to give soup. This method of taking soup has the disadvantages that the molten metal is easily oxidized, the low-quality soup on the surface is easy to be scooped, and the precision of the soup is low. , The initial setting of the amount of soup is complicated and other disadvantages

On the other hand, because the height of the molten metal in the furnace changes frequently, and the height of the molten metal is difficult to detect, it is impossible to determine the height of the molten metal, and it is impossible to draw the molten metal accurately and quantitatively.

[0003] Now some enterprises still use the vacuum quantitative tank to take soup. The vacuum quantitative tank of this soup taking device is fixed vertically and cannot swing.

It is difficult to dock with the inclined die-casting machine press chamber after taking out the soup, and it is easy to damage the soup taking port or cause the molten metal to leak due to the misalignment of the docking
