【考案の詳細な説明】
本考案は、中子を使用して鋳物を製造する鋳型
に関し、殊に鋳型のキヤビテイに溶湯を流入せし
めた際に、中子の巾木が折損するのを防止した鋳
型に関する。[Detailed description of the invention] The present invention relates to a mold for manufacturing castings using a core, and in particular prevents the baseboard of the core from breaking when molten metal flows into the cavity of the mold. Regarding molds.
中子を使用して鋳物を製造する場合には、一般
的に中子を巾木によつて鋳型の一部に支えるもの
であるが、鋳造物形状によつてかかる巾木の強度
が不充分で、キヤビテイへ溶湯を流入せしめた
際、溶湯の浮力圧に負けて巾木が折損する場合が
度度存在した。 When manufacturing a casting using a core, the core is generally supported on a part of the mold by a baseboard, but the strength of the baseboard may be insufficient depending on the shape of the casting. When molten metal was allowed to flow into the cavity, the baseboards often broke due to the buoyancy pressure of the molten metal.

工数を要するとともに材料費の負担を大きくし、
更に、中子の重心重量がアンバランスになるため
取扱い上、中子の折損不良を誘発し鋳物製品の生
産は低下するという欠点を有した。 In order to prevent such breakage, that is, breakage of the core, a core having a baseboard in which a core metal is housed in the baseboard support part, and
A core that has a baseboard whose sand composition has been changed to strengthen the sand, and a core that has a baseboard whose size and shape are unnecessarily large to withstand hot water pressure. However, these require extra man-hours to manufacture and increase the material cost.
Furthermore, since the weight of the center of gravity of the core becomes unbalanced, the core may be broken or damaged during handling, resulting in a decrease in the production of cast products.

である。 The purpose of the present invention is to eliminate these drawbacks and provide a mold that can extremely easily prevent the core baseboard from breaking. This mold is characterized in that a pressurized molten metal space is provided in contact with the end face of the mold.
以下本考案の実施例を図面に基づいて説明す

る。 In FIGS. 1 and 2, reference numeral 11 denotes a mold, and this mold 11 has a core 15 in its cavity 13. The core 15 has a core body 17 in the center.
A baseboard 23 having supporting parts 21, 21 is integrally formed on both sides thereof. This core 15 is attached to the baseboard 2 on the inner wall surface of the cavity 13.
3 is buried horizontally. Inside the mold 11 , a pressurized hot water space 25 is provided at the tip end surface of the baseboard 23 in contact with the tip end surface of the baseboard 23 .

Further, a runner 35 through which molten metal flows is provided in the side feeder space 29.

狭いものなどや小物の製造に有効である。 The mold according to the present invention has a pressurized molten metal space in contact with the end surface of the baseboard of the core installed in the cavity, so when molten metal is poured into the mold, if the cavity is filled with molten metal. Almost at the same time, the pressing waste space is also filled with molten metal, and as a result, the end face of the baseboard is pressed (in this example, toward the core body), and the core is bent due to the buoyancy of the molten metal. The baseboard can withstand stress and will not break. Therefore, unlike conventional core breakage prevention means, the mold according to the present invention can easily prevent core breakage without requiring extra man-hours. In addition, it is particularly effective for manufacturing small items such as molds with narrow circumferences.
このように本考案の実用的価値は甚だ大であ
る。 As described above, the practical value of the present invention is enormous.
