摘要： An intermediate stalk (10) that is used for a low-pressure die-casting apparatus includes a metal covering material (2), and a precast refractory material (1) that is removably fitted into the metal covering material (2), an air release opening (3) being formed between the metal covering material (2) and the precast refractory material (1) when viewed from above. According to the present invention, an intermediate stalk that allows water to be sufficiently released from the refractory heat insulator during heating, does not explode, does not produce cracks in the refractory heat insulator due to the difference in coefficient of thermal expansion between the refractory heat insulator and the metal covering material, and allows easy replacement of the refractory heat insulator, a method of producing the same, and a low-pressure die-casting apparatus can be provided.
