触面５４の隙間が溶湯Ａによって塞がれるため、補助空
間７内の空気は排出不可能となる結果、溶湯はそれ以上
上昇することなない。よって、補助空間７内は加圧空間
として確保される。First, molten metal is poured into the casting space 4. Then, the molten metal A rises in the casting space 4. At this time, the air in the casting space 4 is exhausted to the atmosphere via the contact surface 54. Then, when the molten metal A reaches the boundary between the casting space 4 and the auxiliary space 7, the gap between the contact surfaces 54 is closed by the molten metal A, so that the air in the auxiliary space 7 cannot be discharged, and as a result, the molten metal It will not rise any higher. Therefore, the inside of the auxiliary space 7 is secured as a pressurized space.
そして、前記ガス管８１の開閉弁８２を開放して補助空

加圧空間として確保される。The casting apparatus of the present invention provides an auxiliary space above the casting space in the mold, communicates this auxiliary space with the casting space, and provides a pressurized gas introduction hole in the mold to apply pressure to the auxiliary space. In a casting device that is capable of introducing pressurized gas, a communication passage is provided at the boundary between the casting space and the auxiliary space in the mold, and the casting space is communicated with the atmosphere through the communication passage. A communication passage was provided at the boundary between the casting space and the auxiliary space, and the auxiliary space was communicated with the atmosphere through the communication passage.When pouring molten metal into the casting space, the molten metal rises up the wall of the casting space, but When the molten metal reaches the boundary between the casting space and the auxiliary space, the air in the auxiliary space cannot be discharged, so the molten metal does not rise any further, and therefore the auxiliary space is secured as a pressurized space. .
