  • Patent number: 4034795
    Abstract: A vertical type machine for continuously forming casting molds at high pressure. The machine is supported by a bed plate and has stays extending vertically with a stationary upper frame connected to the stays. An upper mold frame is fixed to the stays while the lower mold frame is mounted on the stays for vertical reciprocation. A match plate is supported on the stays intermediate the upper and lower mold frames for movement in and out of closing engagement with the upper mold frame. The lower mold frame is mounted on horizontally extending rails on its support so that it may be moved into and out of alignment with the upper mold frame. An upper piston-cylinder actuator is mounted of the stationary frame for vertically displacing an upper squeeze plate, and a lower piston-cylinder actuator is mounted on the bed plate for moving a lower squeeze plate vertically.
