Gravity type tiltable metal mold casting machine

Abstract

A gravity type tiltable metal mold casting machine, comprising: a pair of opposing upright supporting frames (); a pair of opposing main rotating shafts () rotatably mounted on the upright supporting frames (); a main frame () suspended from and between the main rotating shafts (); an electric motor () attached to one of the main rotating shafts () for reversibly rotating it and hence the frame (); a drag die plate () vertically moved by mold-fastening cylinders () mounted on a lower part of the main frame (); a metal drag () secured to the drag die plate (), the metal drag having a drag pushing-out mechanism () for pushing an as-cast product out of the metal drag; a pair of opposing horizontal cope tilting shafts () secured to an upper end of the main frame at locations rearward of the main rotating shafts (); a cope-attaching frame () rotatably mounted at one end on the cope tilting shafts (); a cope die plate () secured to a lower surface of the cope-attaching frame (); a metal cope () secured to the cope die plate (), the metal cope having a cope pushing-out mechanism () for pushing an as-cast product out of the metal cope, a ladle () 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 () for reversibly rotating the ladle () 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.
