Description

Technical Field

[0002] At present, automobile engine cylinder head products are relatively complex, and the interior is formed by sand cores. There are many sand cores. When casting the cylinder head, the sand core needs to be placed in the outer mold. The size of the sand core is very critical. All produced sand cores must be sent for inspection to detect the sand core size. If the inspection results are not available, the equipment must be shut down. A large number of inspection resources are required, and continuous production cannot be carried out if the inspection results are not available. Due to the complexity of the sand core of the cylinder head, any problem in the production of the sand core will cause the sand core to deform. After the mold is closed, each sand core has a corresponding clamping position. If the sand core is deformed and placed in the outer mold, the sand core will not be placed in place or the mold sand core will break, and sand will fall off. This will reduce the qualification rate of the cylinder head. For this reason, it is urgent to provide a rapid inspection fixture for the key parts of the sand core of the cylinder head.
