Abstract

PURPOSE: To fill every part of a casting mold with a casting resin liquid and to obtain a good cast article without including bubbles, by filling the resin liquid into the mold under vacuum immediately after the removal of bubbles in the resin liquid under vacuum.
CONSTITUTION: Cocks 16, 16' are opened to charge a main agent 18, and a curing agent 18' in reservoir tanks 15, 15' into a casting resin feeding pot 5 in a vacuum box 1, and then by the operation of a vacuum pump 3, vacuum is applied to the vacuum box 1 and a vacuum box 2 containing a casting mold 6 to remove air bubbles included in the resin liquid 4 in the pot 4. When the removal of the bubbles has beem completed, by the operation of a cock 11 the circuit of the pump 3 is closed, air is introduced through an air inlet 21 to restore the box 1 to its atmospheric pressure state, a cock 9 is opened to feed the resin liquid 4 via a connection pipe 10 into the mold 6 under vacuum, and when the resin liquid 4 overflows from a gas outlet 19, the operation of the pump 3 is stopped, and the cock 9 is closed to stop the feeding of the resin liquid 4. Then, by manipulating a cock 12, air is allowed to flow via an air inlet 22 into the box 2 to restore the interior thereof to atmospheric state.
