供できるようになつている。 Molten metal is supplied from sprue e, passes through runner d, reaches model c, and vaporizes model c. The vaporized gas passes through the gaps in the filler b, enters the vented gas f through the vent h, rises therein and exits to the upper part, where it is ignited by the ignition device i and combusts. On the other hand, the molten metal enters the space after the model c has disappeared, and casting is performed. As shown in FIG. 15, a large number of the flasks a are successively moved in the direction of the arrow Ak, for example, by a moving device j such as a roller, or by a piston rod k operated by hydraulic pressure or the like. This movement is carried out endlessly in a large number of casting flasks a, during which the model c is set, the filling material b is introduced, filling, molten metal is poured, air is vented, ignited, and the product and the filling material b are removed. Retrieval is now performed continuously. This equipment is adapted to provide automated casting equipment.
