本考案は、鋳造用湯口型を造型する際の湯口枠
と湯口管との芯合せ治具に関する。[Detailed Description of the Invention] The present invention relates to a jig for centering a sprue frame and a sprue pipe when molding a sprue mold for casting.
ロール鋳造用鋳型のように直立型の鋳型におい

0.5〜2mの湯口型を継ぎ足して構築されている。
そして各湯口型の湯口枠と湯口管との芯ズレがあ

いて湯口管の芯ずれにもとづく喰い違いがあるた
め溶湯流に乱流が生じ、これが湯口型の溶損およ
び破損を早めて、溶湯中にノロ、砂、ガス等を巻
込み鋳造物の品質の低下をもたらすという問題が
ある。 In upright molds such as roll casting molds, the overall length of the sprue is usually 2 to 12 m.
It is constructed by adding sprue molds of 0.5 to 2 m in length.
If there is a misalignment between the sprue frame and the sprue pipe of each sprue type, when the molten metal passes through the sprue pipe, there will be a misalignment at the joint of the sprue mold due to the misalignment of the sprue pipe, causing turbulence in the molten metal flow. There is a problem in that this accelerates melting and damage of the sprue mold, and entrains slag, sand, gas, etc. into the molten metal, resulting in a deterioration in the quality of the casting.
本考案は、湯口型を造型する際湯口管を湯口枠
に対して、簡単にしかも正確に設置できる芯合せ
治具を提供するものである。 The present invention provides a centering jig that allows the sprue pipe to be easily and precisely installed with respect to the sprue frame when molding the sprue mold.

固定できる構造になつている。 The present invention will be explained based on the embodiments shown in FIGS. 1 to 4. Figures 1 and 2 show the structure of the alignment jig according to the present invention, and Figures 3 and 4 show the structure of the alignment jig according to the present invention for aligning the sprue pipe and the sprue frame. An example of application is shown. Figures 1 and 4
In the figure, the alignment jig consists of a protrusion 1 that can fit into the inner hole of the sprue pipe 3, and a foot 2 attached to the protrusion 1. The tip portion is bent so as to be engaged with the upper outer edge portion 6 of the sprue frame 4 installed in the section. As shown in the figure, the structure is such that the foot part 2 can be fixed simply by placing it on the upper part of the sprue frame 4.
この芯合せ治具を実際に適用するに当つては、
定盤7上面に突出状に設けられた芯出しピン8が

枠4の上端外縁部6に載置する。その後、湯口枠
4と湯口管3との間に砂5を充填し、湯口管3を
湯口枠4に対して固定する。 When actually applying this alignment jig,
A sprue frame 4 is erected on a surface plate 7 so that a centering pin 8 provided in a protruding manner on the upper surface of the surface plate 7 is located at the center. Next, the sprue pipe 3 is installed on the surface plate 7 so that the lower end wraps around the centering pin 8, and the protrusion 1 of the centering jig is inserted into the sprue pipe 3 on the upper end side, and the foot part 2 is attached to the sprue frame 4. It is placed on the outer edge 6 of the upper end. Thereafter, sand 5 is filled between the sprue frame 4 and the sprue pipe 3, and the sprue pipe 3 is fixed to the sprue frame 4.
このように、本考案の芯合せ治具を用いると、
湯口枠に対して湯口管を正確にしかも簡単に芯合
せでき、湯口型を継ぎ足して構築する際湯口枠さ

く砂等の巻込みが防止できるという効果がある。
また造型に際して砂を充填するとき、湯口管の上
端が閉塞されているので砂が湯口管内に漏入する
のを防止する効果もある。 In this way, when using the alignment jig of the present invention,
The sprue pipe can be accurately and easily aligned with the sprue frame, and when constructing by adding sprue molds, if the sprue frame is placed accurately, the sprue pipe will not be misaligned, thus preventing damage to the sprue. This has the effect of preventing entrainment of sand, etc. due to this.
Furthermore, when filling with sand during molding, the upper end of the sprue pipe is closed, which has the effect of preventing sand from leaking into the sprue pipe.
