〔産業上の利用分野〕
本発明は、鋳物の製造方法に関し、更に詳しくは、同−
又は略同−の形状と単重量（鋳物１個当たりの重量）の
鋳物を、溶融金属の一回の供給で複数個製造する鋳物の
製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a casting, and more specifically, to a method for manufacturing a casting.
Alternatively, the present invention relates to a casting manufacturing method for manufacturing a plurality of castings having substantially the same shape and weight (weight per casting) by one feeding of molten metal.
同−或いは略同−の形状及び単重量を有する複数の鋳物
を製造するために以前から用いられている方法の一つに
、いわゆるスタック方式がある。One method that has been used for a long time to produce castings having the same or substantially the same shape and unit weight is the so-called stacking method.
この鋳型の製造方法は、複数の鋳型を垂直に積み重ね、
各々の鋳型のキャビティが垂直に積み重ねられた鋳型集
合体を形成し、該鋳型集合体の近傍に設けた一本の垂直
湯道とそれから派生して前記キャビティに連なる水平湯
道とを介して溶融金属を先ず最下部のキャビティに満た
し、以後、順次下から上へ向かって各キャビティを満た
してゆ（方法である。This mold manufacturing method involves stacking multiple molds vertically.
The cavities of each mold form a vertically stacked mold assembly, and melting is carried out through one vertical runner provided near the mold assembly and a horizontal runner that is derived from the vertical runner and continues to the cavity. The method is to first fill the lowest cavity with metal, and then fill each cavity in sequence from bottom to top.
上記方法における留意点の一つは、溶融金属が確実に最
下部のキャビティから順次上に位置するキャビティを満
たしてゆくようにすることである。One of the considerations in the above method is to ensure that the molten metal fills the cavities located successively from the bottom cavity upward.
つまり、溶融金属が先ず最下部のキャビティのみに供給
され、その間は他の上部のいかなるキャビティにも全く
供給されないようにし、上記の最下部のキャビティが溶
融金属で完全に満たされた後に初めて該最下部の直ぐ上
に位置するキャビティに溶融金属が供給され、充満され
るようにする必要があるということである。That is, the molten metal is first supplied only to the bottom cavity and not at all to any other upper cavity in the meantime, and only after said bottom cavity is completely filled with molten metal. It is necessary to ensure that the cavity located directly above the lower part is supplied with molten metal and filled.
それは、より下に位置するキャビティが溶融金属で満た
されつつある時に極少量であっても、そのキャビティよ
り上に位置する他のキャビティに溶融金属が流入すると
、この少量の溶融金属と、後に該キャビティに供給され
る溶融金属との間に温度差が存在することになり、これ
が鋳物の欠陥に結びつくことになるからである。Even if the amount of molten metal flowing into another cavity located above the lower cavity is filled with molten metal, this small amount of molten metal will be This is because there will be a temperature difference between the molten metal and the molten metal supplied to the cavity, which will lead to defects in the casting.
従って、本発明の目的は、スタック方式による鋳物の製
造方法において、より下部のキャビティからその上に位

The liquid passes sequentially through the second runner 7, branch runner 8 and product runner 9, and first fills the cavity 2a of the lowest mold of the mold assembly 4, as shown in FIG. Next, the cavities 2c, 2d, etc. of the mold, starting from the mold cavity 2b near the bottom mold, are successively filled.
The above-mentioned molten metal 13 is filled in the order of . and all cavities 2 are filled with the above-mentioned molten metal 13. Thereafter, a casting can be produced by removing the filled metal using a conventional method.

B, C, and D have a relationship of A>C>B>D. In order to maximize the cross-sectional area A of the first runner 6 in this way, sufficient pressure is applied to the entire molten metal 13 fed into the mold section 1 when producing the casting as described above. be able to. Therefore, for every cavity 2, the molten metal 13
Easily and reliably supplying the material makes it combustible.

止することができる。Further, the cross-sectional area C of the branch runner 8 provided perpendicularly to the second runner 7 from the second runner 7 is larger than the cross-sectional area B of the second runner 7. be. Therefore, the branch runner 8 plays the role of a temporary molten metal reservoir, and therefore, before the molten metal 1) 13 completely fills the cavity 2a, the molten metal 1) 13 flows into the cavity 2b located above the cavity 2a.
It is possible to effectively prevent even a very small amount of molten metal from flowing into, etc.
更に、上記製品湯道９は、その断面積りが最小に形成さ

物欠陥の発生の防止に有効である。Further, since the product runner 9 has a minimum cross-sectional area, the molten metal 13 can be gradually and quietly flowed into the cavity 2. Therefore, for each cavity 2, gently pour the molten metal 13 from its bottom.
As a result, all of the cavities 2 can be completely filled with the molten metal 13. At this time, since each cavity 2 is communicated with the gas vent space 10 via the gas vent path 1), the gas generated from the mold during the supply of molten metal and its curing can be effectively discharged to the outside. This is effective in preventing casting defects caused by gas.

The second runner 7 (
The product runner 9 is preferably formed symmetrically with respect to the second runner 7 (branch point), and the product runner 9 is also formed symmetrically with respect to the second runner 7, respectively. It is preferable to provide the same number of molten metals 13 because the molten metal 13 can be evenly supplied into the cavity 2.
