Sealing device for die casting leakage detection

Abstract

The invention discloses a sealing device for die casting leakage detection. The device comprises a circular ring, threaded cylinders are fixedly assembled on the two sides of the lower surface of thecircular ring, the inner walls of the threaded cylinders are in threaded connection with one ends of bolts, the other ends of the bolts are rotationally assembled with one ends of rotating rods, and bottom plates are fixedly assembled at the other ends of the two rotating rods. An air bag is matched with a rubber pad, an inflator is matched with a one-way valve, the air bag is inflated, the air bag expands continuously, and the rubber pad is pushed to approach the die casting; when the rubber pad is attached to the die casting, a small amount of air is continuously introduced into the air bag;the expanded air bag pushes the rubber pad to be tightly attached to the die casting and deform after making contact with the die casting, and part extends to the hole in the die casting; and the rubber pad can be used according to the die castings of different sizes and can deform at will under pushing of the air bag, the effect of sealing the hole is achieved, the application range is wider, and the practical performance is high.

Description

technical field [0001] The invention relates to the technical field of sealing devices for leak detection of die castings, and specifically relates to a sealing device for leak detection of die castings. Background technique [0002] Die-casting is a kind of pressure-casting part. It uses a pressure-casting mechanical die-casting machine equipped with a casting mold to pour liquid copper, zinc, aluminum or aluminum alloy into the feed port of the die-casting machine, and passes through the die-casting machine. Die casting, casting copper, zinc, aluminum parts or aluminum alloy parts of the shape and size limited by the mold, such parts are usually called die castings. Die-casting parts have different names in different places, such as die-casting parts, pressure castings, die-casting parts, die-casting aluminum, die-casting zinc parts, die-casting copper parts, copper die-casting parts, zinc die-casting parts, aluminum die-casting parts aluminum die-casting parts, aluminum d...
