Description

Sand core positioning device for casting Technical Field The utility model relates to the technical field of casting equipment, in particular to a sand core positioning device for casting. Background The sand core is a hollow sand mold made from a sand core box, which is commonly used in casting processes to place the sand core in a casting box mold so as to leave a certain space when liquid metal is poured into the sand mold. After casting, the core can be easily removed, leaving an internal cavity that can be the hollow of the object. The sand core can be used for manufacturing various parts, such as an automobile engine cylinder body, a cylinder head, other mechanical parts and the like. The sand core is a very important responsible part because it can withstand high temperatures and pressures, thereby ensuring the stability and durability of the parts during use. When the sand core is manufactured, certain sand core manufacturing process and equipment, such as a sand core machine, a core box, an adhesive and the like, are required to ensure the quality and the dimensional accuracy of the sand core. In order to prevent the sand core from shifting or falling off during casting, it is often necessary to fix it with the sand mold. The position of the sand core in the sand mould is generally determined by a sand core seat, and the sand core seat is a groove reserved in the sand mould and corresponding to the sand core. In casting, the sand core needs to bear the action of high temperature and pressure, so the fixing mode of the sand core needs to ensure the safety and reliability. After the sand core has completed the casting task, the sand core also needs to be taken out. There is a need for a sand core positioning device to secure a sand core in a sand core seat that facilitates casting and later removal of the sand core. Disclosure of utility model The utility model aims to provide the sand core positioning device for casting, which can conveniently and rapidly position the sand core in the sand core seat, is convenient to take out in the later period, and is safe and reliable to fix.
