[0002] At present, the manufacturing of sand molds is to use patterns (where the patterns can be wooden patterns, metal patterns, plastic patterns, or lost foam patterns, etc.) to obtain the shape, size and precision of the casting cavity. During the pouring and filling process of the casting, the binder and the like encounter the high-temperature molten metal, and a large amount of gas is generated in the cavity, which needs to be discharged through the sand mold body or the exhaust duct. Otherwise, the air pressure in the cavity is too high, and the molten metal cannot fill the cavity during pouring or chokes, which reduces the quality of the casting. Therefore, it is necessary to drill air holes on the sand mold body to prevent the gas generated during pouring and the original gas in the cavity from not being discharged, causing defects such as air holes in the casting and causing the casting to be scrapped.
