Abstract

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.

First claim

What is claimed is:

1 . A casting system comprising:
a plurality of mold tables on each of which at least one centrifugal casting mold is provided; a molten metal pouring truck that moves to a position of each of the plurality of mold tables and pours molten metal into the mold installed on each mold table; a molten metal supply furnace that supplies molten metal to the molten metal pouring truck and; a plurality of cooling devices configured to cool the molds provided on the mold tables, wherein the mold tables are rotatable, and the molten metal pouring truck travels on a straight rail.

2 . The casting system according to claim 1 , further comprising a plurality of unit devices provided for the plurality of respective mold tables, wherein each of the unit devices includes at least one of a mounting-demounting unit configured to perform mounting and demounting of a lid member mounted at an end part of each of the molds, a removal unit configured to pull out a cast shaped inside the mold from the mold, a cleaning unit configured to clean the mold, and a lining unit configured to apply mold wash to the mold.

3 . The casting system according to claim 2 , wherein
the mold tables are rotatable, and on each of the mold tables, a plurality of the molds are disposed at different positions in a rotational direction of the mold table such that when a certain mold is positioned to be able to face the molten metal pouring truck, a mold different from the certain mold faces the unit devices.

4 . The casting system according to claim 3 , wherein
each of the mold tables is sandwiched between a movement region of the molten metal pouring truck and a corresponding one of the unit devices, and on each of the mold tables, the molds are disposed at respective positions shifted by 180° from each other in the rotational direction.

5 . The casting system according to claim 2 , wherein
on each of the mold tables, a plurality of the molds are disposed at respective different positions in the rotational direction, and the molten metal pouring truck includes a plurality of molten metal pouring units that simultaneously pours molten metal into the plurality of respective molds.

6 . The casting system according to claim 2 , further comprising a conveyance device configured to convey casts pulled out by the removal units of the unit devices.

7 . The casting system according to claim 6 , further comprising:
an outer wall part provided around the mold tables, the unit devices, and the conveyance device; and an inner wall part provided between the plurality of mold tables inside the outer wall part.

8 . The casting system according to claim 1 , comprising a plurality of the molten metal pouring trucks, wherein one of the plurality of molten metal pouring trucks pours molten metal into each of the molds provided on the plurality of mold tables.

9 . The casting system according to claim 1 , wherein the plurality of cooling devices are provided opposite the plurality of respective mold tables.

10 . The casting system according to claim 1 , wherein the mold tables are provided with roller devices configured to rotate the molds, and the casting system further includes a control unit configured to control rotational speeds of the roller devices.
