A method for producing a salt core includes a step A of adding a saturated sodium chloride aqueous solution to a sodium chloride crystal that is granular, to prepare a slurry mixed material of sodium chloride and water, a step B of subjecting the slurry mixed material to pressure molding to obtain a molded article, and a step C of drying the molded article to remove moisture.

Method for producing salt core

A core grasping apparatus according to the present disclosure grasps a core including a core main body and a core print provided at one end of the core main body. The core grasping apparatus includes: a first holding device and a second holding device respectively including expandable and contractible first and second holding parts; and a turning suppression part configured to suppress the core from turning upon the core print being grasped by the first holding device and the second holding device. The first holding device and the second holding device grasp the core print by respectively expanding the first holding part and the second holding part, and the turning suppression part applies a force that suppresses a turning moment acting on the core to the core print.

Core grasping apparatus

Provided is a core grasping method of grasping a core using a core grasping apparatus. The core grasping apparatus includes grasping devices respectively having expandable and contractible grasping parts. The core includes holes, and at least one of the holes has an inside diameter that decreases in the opposite direction from a direction of a turning moment occurring on the core. The core grasping method involves, when grasping the core, expanding the grasping parts inserted in the holes so as to bring the grasping parts into contact with inner walls of the holes of the core, and grasping the core and applying a force that suppresses the turning moment to the core.

Core grasping method

A core conveying device includes a plurality of holding devices, a support section, a moving device, and a mounting table. The support section has a hole formed at a position corresponding to a positioning pin and is connected so as to slide in a horizontal direction with respect to the moving device. A size of a lower end opening of the hole is larger than a size of an upper end of the positioning pin. The support section is configured such that, when the support section is moved downward so as to grip the core, as the positioning pin abuts against an inner surface of the hole and the support section slides in the horizontal direction with respect to the moving device, a position of the support section in the horizontal direction with respect to the core is determined.
