The invention discloses a centrifugal pouring method for water glass
investment casting, relates to a
casting pouring method, and solves the problem that castings are prone to unqualified castings during pouring of water glass
investment casting. Put the water glass shell into the iron box, put steel sand in the iron box, the steel sand completely covers the water glass shell, then put the iron box on the centrifugal rotary table, pour the molten iron into the water glass through the
sprue In the mold shell, after the pouring is completed, let it stand for 30 seconds, turn on the centrifugal rotary table, and rotate the centrifugal rotary table at a speed of 80-100 rpm for 10-15 minutes to obtain qualified castings. The invention strengthens the shell mold by embedding steel sand, prevents the
volume expansion of the shell mold during the pouring process, makes the
casting casting uniform by adopting the centrifugal rotating
workbench, accelerates the filling and filling of the hot joint part of the casting, and reduces the static pressure by reducing the volume of the
sprue , Reduce the pressure on the shell, avoid the problems of shrinkage cavity,
shrinkage porosity or shell deformation, and the qualified rate of castings has increased from the original 75% to more than 98%.
