Abstract

PURPOSE: To obtain a good cast article without including bubbles, by filling casting resin raw liquids contained in tanks which is kept in a vacuum state via a vacuum box which is in a vacuum state into a casting mold which is also in a vacuum state.
CONSTITUTION: By the operation of a vacuum pump 6, the reservoir tanks 1, 1' and vacuum boxes 2, 3 are made vacuous both to remove bubbles included in the casting resin raw liquids (such as a main agent, a curing agent, etc.) contained in the tanks 1, 1' and to keep the vacuum boxes 2, 3 in a vacuum state. Then, cocks 10, 10' are opened to introduce the raw liquids in the tank 1, 1' via supply tubes 12 into a resin feeding pot 4 situated in the box 2, the raw liquids are mixed by a stirer 8, then the cock 16 is opened to drop the mixed resin liquid into the casting mold 5 positioned in the box 3, and when the resin liquid overflows from a gas outlet 21, the cock 16 is closed to terminate the filling of the resin liquid. Subsequently, a cock 19 is opened to introduce compressed air into the box 3 to keep the interior of the box 3 in a pressurized condition so that the resin is filled under pressure into the mold 5, and thereafter the interiors of the boxes 2, 3 are restored to atmospheric pressure and the resin is cured.
