METHOD OF AUTOMATIC BALANCING OF DEVICE FOR CENTRIFUGAL CASTING AND MECHANISM FOR EMBODIMENT OF THE METHOD Russian patent published in 1998 - IPC

FIELD: manufacture of dental prostheses and jewelry by the method of centrifugal casting. SUBSTANCE: method consists in elimination of unbalance by installation of additional weight. The mechanism for embodiment of the method has lever 2 installed on shaft 1. Located on one arm of lever is casting mold 3 with melting crucible 4; and installed on the other arm of lever is balancing weight 5 and reservoir 6 with liquid. The second reservoir 7 is attached to shaft and connected with reservoir by means of channel 9. Lever 2 is capable of linear motion over shaft. During rotation of the device, occurring mass unbalance is compensated by overflow of liquid from reservoir 7 to reservoir 6. Upon stopping of rotation, liquid under gravity flows from reservoir 6 through channel 9 to reservoir 7. Provision is made for smooth rotation of lever without vibration. EFFECT: higher efficiency. 7 cl, 1 dwg
