A casting die device and a casting method. The casting die device has a core pin for forming an inner hole in a casted article. The core pin is a hollow body, and a pressurizing pin is inserted into a hollow inner part of the core pin. Vibrations from a vibrator of a micro vibration machine are imparted to the pressurizing pin via a vibration transmission member. The vibrations further propagate to the core pin from the pressurizing pin, and then propagate to the area surrounding the core pin in a molten metal that has been poured into a cavity.

A die casting mold includes a mold frame with at least two mold inserts and with at least one slider, the mold frame comprising a frame pocket for arranging the at least two mold inserts and the at least one slider, the at least two mold inserts delimiting a cavity with an undercut corresponding to the at least one slider, the mold frame comprising a first and a second mold frame halves disposed on opposite sides of a parting plane. At least one of the first and the second mold frame halves is formed by a plurality of mold frame parts connected to one another in a form-fitting manner, one of the plurality of mold frame parts having a locking surface, which, as viewed along a locking axis, is effective as a slider lock against a displacement of the at least one slider directed outwardly as viewed from the cavity.

A casting mold device includes a lower die and an upper die capable of being attached to or detached from the lower die and is configured to produce a cylinder head having spark plug mounting portions. In particular, the casting mold device includes: i) a plurality of core pin assemblies mounted in the upper die to form the spark plug mounting portions and having cooling air flow paths formed therein, ii) a cooling unit installed on the upper die and including cooling air inlet portions and cooling air outlet portions respectively connected to the cooling air flow paths of the core pin assemblies, and iii) a sealing unit coupled to the cooling unit and the upper die to seal portions between the core pin assemblies and the cooling unit.

An assembly for producing a molding, made of removable material, of a turbomachine blade, includes an injection mold for the removable material in which a first core element and a second core element are mounted in a predetermined molding position, wherein the first and second core elements extend in a first direction. The mold includes a first face for molding a pressure-side face of the blade and a second face for molding a suction-side face of the blade and arranged facing the first face in a second direction perpendicular to the first direction.

Retaining members hold the cores in position in the injection mold.

A casting die is formed from a mold half with a mold insert disposed at least partly in a relief of the mold half. The mold insert is mounted movably in the relief.

A first die segment for forming an internal combustion engine block has cylindrical projections, and die core pieces disposed about the cylindrical projections. A second die segment has die core stubs positioned so as to extend between adjacent die core pieces when the segments are brought together. An engine block formed by the die segments has cylindrical bores formed by the cylindrical projections extending from the deck of the block and voids formed by the die core pieces also extending from the deck and disposed about the cylindrical bores. Pockets formed by the die core stubs extend into sides of the engine block between adjacent voids. The engine block is worked below the level of the deck to undercut each of the pockets, removing material between them and the voids to result in an interconnected water jacket extending about the cylindrical bores, while leaving the deck closed.
