DEVICE FOR CLOSING MOULD OF CASTING MACHINES Russian patent published in 1998 - IPC

FIELD: casting technology. SUBSTANCE: stationary fixing plate 2 and/or end plate 4 are mounted on corresponding cheeks of frame 1 by means of at least two supporting axles 9, 10 and 11, 12 each, which are horizontally located above and below axis 7 of injection and across this axis. Lower supporting axles 10, 12 are connected with plate 2 and/or with plate 4 by means of members 13 which are resiliently deformable so that deformation of C-shaped frame 1 caused by closing force is compensated by preset elastic deformation. In result, surfaces 2.1 and 3.1 of fixing plates 2, 3 for fastening of half-moulds of casting mould 8 remain in vertical position. Axles 9, 11 are located in common horizontal plane above injection axis 7. Axles 10, 12 are below injection axis 7. Members 13 can be made in the form of rods or supporting brackets located in pairs and rigidly connected with plates 2, 4, and are weakened in middle part by through-holes or milled recesses. EFFECT: high efficiency. 27 cl, 14 dwg
