DEVICE FOR REMOVING CASTING MOLD IN INVESTMENT CASTING METHOD

摘要

PURPOSE:To provide a titled removing device which removes successively and satisfactorily expendable patterns from the lower part by carrying and transferring casting molds contg. the expendable patterns into a shielding box while rotating said molds, irradiating microwaves thereto and raising successively the bottom end of a shielding part. CONSTITUTION:The casting molds 3 contg. the expendable patterns by an investment casting method are carried and transferred into the shielding box 1 while the molds are rotated by revolving shafts 7. The microwaves are irradiated through irradiation ports 4 of the box 1 into said box and the bottom end of the microwave shielding member 2 is successively raised. The expendable patterns are successively and successively heated from the lower part to melt and flow out. The casting molds contg. the patterns are thus satisfactorily removed and ejected.
