Abstract A DIE CASTING APPARATUS AND METHOD IN WHICH THE UPPER MOLD PART IS CARRIED BY A PRESS HEAD FOR VERTICAL MOVEMENT TOWARD AND AWAY FROM AN INJECTION CYLINDER, AND THE LOWER MOLD PART IS ATTACHED TO A SHEAR EXTENSION FOR LATERAL MOVEMENT BETWEEN THE INJECTION CYLINDER WHERE MOLTEN METAL IS INJECTED INTO THE CLOSED MOLD HALVES AND A STRIPPING TABLE WHERE THE CAST ARTICLE IS REMOVED FROM THE LOWER MOLD PART. AN OPENING IN THE SHEAR EXTENSION RECEIVES THE METAL RESIDUE FROM THE INJECTION CYLINDER FOR DISPOSAL DURING SUCH LATERAL MOVEMENT OF THE LOWER MOLD PART TO THE STRIPPING TABLE.
