A mold used for centrifugal casting includes a mold body formed in a cylindrical shape and a lid member (40) that is detachably assembled to an end part of the mold body in an axial direction. The lid member includes a lid body (41) that is attached to an opening part formed at the end part of the mold body, a protrusion part (450) that is fitted to the mold body, and a spring that applies elastic force to the lid body in a direction in which the lid body closely contacts the mold body.

A molding machine for molding material is provided. The machine includes a cavity to be filled with molten metal and a conduit system leading to the cavity, thus forming a system of interconnected hollow spaces. At least one pressure member is moveable in at least part of the conduit system. A centrifugal pump in fluid communication with a reservoir of molten metal is provided, the pump providing molten metal to the hollow space receiving the at least one pressure member.

A cooling device (21) includes radiation thermometers (51 to 55), a plurality of nozzle parts, a plurality of electromagnetic valves (V.sub.1 to V.sub.5), and a control device (60). The radiation thermometers detect pre-cooling temperatures that are temperatures at a plurality of places on the mold before cooling water is sprayed from the plurality of nozzle parts to the mold. The control device individually sets a cooling time to each of the plurality of places on the mold based on a deviation between the pre-cooling temperature at the place on the mold and a target temperature and controls the electromagnetic valves based on the cooling times individually set to the plurality of respective places on the mold.

A centrifugal casting device casts a cast product by pouring molten metal into a mold while rotating the mold, and includes: a control unit for controlling the rotational speed of the mold; and a determination unit for determining whether or not the head position of the molten metal flowing in the direction of a rotation axis of the mold has reached a predetermined position. The control unit rotates the mold at a first rotational speed, and rotates the mold at a second rotational speed in a case where the determination unit determines that the head position has reached the predetermined position.

A casting system (10) includes a plurality of mold tables (41 and 42), molten metal pouring trucks (21 and 22), and a molten metal supply furnace (30). The mold tables are each provided with centrifugal casting molds (81 to 84 and 91 to 94). Each molten metal pouring truck can move to the position of each mold table and pour molten metal into the molds installed on the mold table. The molten metal supply furnace supplies molten metal to the molten metal pouring trucks.
