Patent ID: 6942010

Claim:
A gravity type tiltable metal mold casting machine, comprising: a pair of opposing upright supporting frames ( 2 , 2 ); a pair of opposing main rotating shafts ( 3 , 3 ) disposed on an axis of rotation and rotatably mounted on the upper ends of the upright supporting frames ( 2 , 2 ); a main frame ( 4 ) fixedly mounted on the main rotating shafts ( 3 , 3 ) such that the main frame is suspended from and between the main rotating shafts ( 3 , 3 ); an electric motor ( 19 ) attached to one of the main rotating shafts ( 3 , 3 ) for reversibly rotating the main rotating shaft ( 3 ) and hence the frame ( 4 ); a drag die plate ( 6 ) vertically moved by mold-fastening cylinders ( 5 , 5 ) mounted on a lower part of the main frame ( 4 ); a metal drag ( 10 ) secured to the drag die plate ( 6 ), the metal drag having a drag pushing-out mechanism ( 23 ) for pushing an as-cast product out of the metal drag; a pair of opposing cope tilting shafts ( 13 , 13 ) horizontally disposed on a horizontal axis and secured to an upper end of the main frame at locations rearward of the main rotating shafts ( 3 , 3 ); a cope-attaching frame ( 14 ) rotatably mounted at one end on the cope tilting shafts ( 13 , 13 ); a cope die plate ( 16 ) secured to a lower surface of the cope-attaching frame ( 14 ); and a metal cope ( 17 ) secured to the cope die plate ( 16 ), the metal cope having a cope pushing-out mechanism ( 26 ) for pushing an as-cast product out of the metal cope ( 17 ); a ladle ( 21 ) rotatably mounted about a horizontal axis of rotation, the horizontal axis of rotation being located rearward of the assembly of the metal cope and drag; and an electric motor ( 9 ) for reversibly rotating the ladle ( 21 ) about the horizontal axis of rotation, wherein the center of the assembly of the metal cope and drag is substantially on the axis of rotation of the main rotating shafts ( 3 , 3 ).
