Abstract

1363602 Foundry moulding apparatus NAUCHNO-ISSLEDOVATELSKY INSTITUT SANITARNOI TEKHNIKI and SPETSIALIZIROVANNAYA PROEKTNO-KONSTRUKTORSKAYA NALADOCHNAYA ORGANIZATSIA ROSORGTEKHSTROM 15 Aug 1972 36648/73 Divided out of 1363601 Heading B3F An apparatus for making foundry cores according to the method disclosed in Specification 1,363,601 comprises a hopper containing moulding sand 1, a mixer-conveyer 4, which is fed with sand from the hopper and foaming and binding agent from a pipe 3 to form a fluid sand moulding mixture, an injection chamber 11 including a telescopic injection piston 12, a reciprocable valve plate 15 including an injection nozzle 16 arranged to cover the outlet of the injection chamber 11 and a core-box 19 arranged to receive a charge of fluid sand moulding mixture from the injection chamber 11 through the nozzle 16. The core-box 19 is heated to effect curing of the moulding mixture. Pressure may be built up in the core-box 19 in two separate stages by employing the telescopic injection piston 12. After injection and pressure build-up the pressure in the core-box 19 is maintained by sealing its outlet 20 with a slide valve 21. The nozzle 16 containing residual moulding mixture in a non-fluid state is moved rightwards as shown and split longitudinally to deposit the residue into a lifting conveyer 23 which returns the residue to the mixer-conveyer 4 for refluidizing.
