As shown in FIG. 4, a pipe-shaped hollow member 8 with central portions 9.9 at both ends is placed in a mold cavity 5 formed in advance by the inner walls 4 of the upper mold 2 and lower mold 3, with a frame extending therebetween. After that, the molten metal is poured into the mold cavity 5 and the hollow member 8 is integrally cast, and as shown in FIG. At the end face 16.16, cut and remove the hollow casting 1.
It was manufactured.

である。[Structure of the Invention] (Means for Solving the Problems) The structure of the invention is that, in a method for producing a hollow casting in which a hollow member is cast, the hollow member is provided with a protruding portion that protrudes from the end face of the hollow casting. At the same time, this is a method for manufacturing a hollow casting, characterized by providing a casting part near the base of the protruding part.

。(Function) The function of the present invention is to provide a protruding portion protruding from the end face of the hollow casting in the hollow member in a method for producing a hollow casting in which a hollow member is cast, and to provide a cast wall in the vicinity of the base of the protruding portion. Since this is a manufacturing method for hollow castings characterized by the provision of a hollow part, when molten metal is poured into the mold cavity, the molten metal is difficult to cool due to the dead part of the casting, and the hollow part prevents the molten metal from cooling down into the casting body. It adheres well.

A mold side central portion 7.7 is formed on the mold matching surface 6 in the mold cavity 5 formed by the inner wall 4 of the upper mold 2 and the lower mold 3, and a pipe-shaped hollow member 8 is formed in the mold side central portion 7.7.
The outer peripheral surface of the hollow member 8 is inserted into the inner wall 4 of the meeting portion 10.10 of the mold side inner portion 9.9 and the mold cavity 5. A mold 12 in which a recess 11.11 is formed to face the
A molten metal is poured into the mold cavity 5, and when the molten metal solidifies, a hollow casting 1 as shown in FIG. 2 is completed. That is, a cast body 13 is provided around the outer circumference of the hollow member 8 from the center to the vicinity of both ends, and at both outer ends of the cast body 13, portions corresponding to the recesses 11 and 11 are formed into cast waste portions 14. .14
The casting part 14.14 is connected and fixed as
Projections 15, 15 of a hollow member 8 are formed to be exposed at both outer ends of the hollow member 8, and the hollow member 8 is integrally cast into the casting body 13.
