TECHNICAL FIELD

[0002] A sand core is a hollow sand mold made from a sand core box, which is usually used in the casting process. It is placed in the casting box model to reserve a certain space when liquid metal is poured into the sand mold. After casting is completed, the sand core can be easily removed, leaving an internal cavity that can become a hollow part of the object. Sand cores can be used to manufacture various components, such as automobile engine blocks and cylinder heads, as well as other mechanical parts. The sand core is a very important and responsible component because it can withstand high temperatures and high pressures, thereby ensuring the stability and durability of the component during use. When making a sand core, certain sand core making processes and equipment are required, such as a sand core machine, a core box, a binder, etc., to ensure the quality and dimensional accuracy of the sand core. In order to prevent the sand core from moving or falling off during casting, it is usually necessary to fix it with the sand mold. The position of the sand core in the sand mold is determined by the sand core seat, which is a groove reserved in the sand mold corresponding to the sand core. In casting, the sand core needs to withstand high temperature and pressure, so its fixing method also needs to ensure its safety and reliability. After the sand core completes its casting task, it also needs to be removed.
