Claims

[Claims for Utility Model Registration] (1) In a mold flask for casting a fugitive model in which the fugitive model is buried in foundry sand, a plurality of small holes communicating with the inside of the flask are formed at the bottom of the flask. A suction section is formed, and a plurality of pipes are attached in an annular shape along the side wall of the mold flask and communicated with the suction section, and the plurality of pipes are arranged above the height of the fugitive model. A mold flask for fugitive model casting, characterized in that a plurality of small holes for suction are formed on the circumferential surface of the flask. (2) The suction section at the bottom consists of a pipe formed into an annular planar shape, and a plurality of pipes arranged inside the annular pipe in the same plane as the annular pipe, and A plurality of pipes along the side wall of the mold flask are attached to the pipe, and the height of the fugitive model of the plurality of pipes arranged in the same plane as the annular pipe and the plurality of pipes along the side wall of the mold flask is A mold flask for fugitive model casting, characterized in that a plurality of small holes for suction are formed on the circumferential surface of the upper part. (3) The suction part at the bottom is formed with multiple small holes,
and a suction section extending over substantially the entire surface of the bottom, and a plurality of pipes communicating with the suction section are installed in an annular arrangement along the side wall surface of the mold flask, and their attachment positions can be selectively changed. A flask for casting a fugitive model, characterized in that the plurality of pipes have a plurality of small holes formed on the circumferential surface above the height of the fugitive model.
