Method for producing lost casting core with shape-fit connection
A recently granted patent (Publication Number: US11890669B2) discloses a method for producing a lost casting core in a core box composed of at least two parts. The core box delimits a mold cavity that determines the shape of the casting core, with an inner surface provided in the core box reproducing the side surface of the casting core. The method involves producing a casting core insert from a molding material, positioning it in the mold cavity, introducing additional molding material to complete the casting core, and solidifying the material to form a connection between the insert and the core.
Furthermore, the patent includes various claims related to the method, such as using different molding materials for the insert and the remainder of the casting core, imparting surface structures to the insert for coupling with the molding material, detecting the volume of introduced material, and providing additional molded elements for quality control purposes. The method can be repeated in a serial sequence with the core box containing multiple mold cavities for continuous production of casting cores. These claims highlight the innovative aspects of the method and its potential applications in the casting industry for efficient and precise core production.
