Abstract

PURPOSE: To make it possible to mold with a single molding machine by accomodating partial cores into the parts insufficiently filled up with casting sand for providing an efficiently working finished core having sufficient strength and highly accurate dimensions even when the core shape is complicated.
CONSTITUTION: Opening partial molds 2, 3, partial cores 11, 12 made of thermoplastic resin are pressed into the prescribed regions 4b, 4c of a cavity, the end elevations 11a, 12a contacting with the part 4a unfilled up with casting sand of the main cavity are applied with volatile rapid drying solvent 13. Next both partial molds 2, 3 are put together and the casting sand 14, mixture of thermoplastic resin and volatile rapid drying solvent, fills up the hollow parts 4a, 5, 6 and the resin within the casting sand 14 is united with the resin on the partial core end elevations 11a, 12a. Hereafter the hollow parts 4, 5, 6 are supplied with compressed air for vaporizing and exhausting out of an outlet 9 to finish the core. Taking out the core by opening the partial molds 2, 3 the partial cores are repeatedly used in their capacity.
