Technical Field

The utility model relates to the technical field of sealing detection of die castings, in particular to a die casting quality detection device.

Background Art

At present, die casting is a common manufacturing process used to produce various metal die castings such as aluminum alloys and zinc alloys. However, due to the influence of various factors in the manufacturing process, die castings may have defects such as pores and tiny cracks, which will affect the air tightness of die castings. Therefore, it is very necessary to perform air tightness testing on die castings.

In the prior art, pipe connectors are also generally formed by die casting. When testing the internal sealing performance, it is necessary to seal both ends of the pipe connector, pass gas of a certain pressure, and observe whether the pressure decreases within a certain period of time through a pressure gauge to determine whether there is a leak. The sealing performance of the pipe connector is tested in turn. However, when the internal air pressure of the pipeline is relatively small in the case of a leak, this method takes a long time to detect the pressure change through the pressure gauge, and the overall detection efficiency is low. Therefore, there is an urgent need for a die-casting quality detection equipment.
