優れた品質で能率良く鋳造する方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for casting metal, and more particularly, to a method for casting metal, and more particularly, mold sections having a particular configuration are installed on a plane and molten metal is supplied to one common sprue so that identical or nearly identical The present invention relates to a method for efficiently casting castings having the same shape and unit weight (unit weight refers to the weight per casting) with excellent quality.

等の欠点を有する。 A method traditionally used to produce multiple castings with the same or nearly the same shape and weight is to stack the cavities vertically and place the runners vertically so that the cavities are stacked vertically. A method is used in which molten metal is supplied to first fill the lowest cavity and then fill the cavities sequentially from the bottom to the top (the so-called stack method). However, with this method, there is a risk that, for example, the flow of molten metal falling vertically down the runner may be disrupted, air or foundry sand from the mold section may be mixed into the molten metal, resulting in defective castings. The molten metal filling the lower cavity is subject to high static pressure, and this static pressure can cause the mold walls to break and the molten metal to flow out. It is necessary to clamp the mold section with strong force, a lot of time and effort is required to set the mold sections, and the productivity of castings is reduced.

る等の問題がある。 Still another method, as seen in Japanese Patent Publication No. 57-14251, is to have one common sprue and one common runner, with the common runner serving both as a pool and a riser; A method has been shown in which a cavity is placed at the bottom of each molten metal pool, and a mold section is used in which the walls forming the molten metal pool are sloped to prevent turbulence of the molten metal. Since there is only one runner in common, in order to produce more castings with the same or nearly the same shape and unit weight, multiple separate mold sections must be prepared, and There are problems such as the need to construct a mold so that the walls that make up the structure are sloped.

い。 First, a mold section (including a weir and cavity not shown) as shown in FIG. 1 is set up on a flat surface, and molten metal is supplied from a sprue 2.
The molten metal first fills the horizontal runner 1, then flows into each branch runner 3, and then flows into each product runner from the starting point B 1 to B 4 of the product runner 4 closest to the horizontal runner. , filling the cavity closest to the horizontal runner through the weir. Since the molten metal falls downward at the starting points B 1 to B 4 of the product runners, only after the molten metal has filled the cavities closest to horizontal runner 1 can the subsequent branch runners, product runners, weirs and It does not flow into the cavity. In addition, the cross-sectional area of horizontal runner 1 is uniform, and the cross-sectional areas of each branch runner and product runner are set equal, so the flow of molten metal is smooth, and each product runner has a uniform cross-sectional area. The weirs and cavities connected to the are filled with molten metal almost simultaneously. In this way, by supplying molten metal from the common sprue 2, the cavity closest to the horizontal runner is first filled with molten metal, and then the subsequent cavities are sequentially filled to obtain a plurality of castings. can. In carrying out the present invention, in order to make the flow of molten metal smoother, it is preferable to establish a certain relationship between the cross-sectional areas of the sprues, runners, and weirs. That is, when the area of the sprue is X, the cross-sectional area of the horizontal runner and the branch runner is Y, and the cross-sectional area of the weir is Z, it is preferable to set so that Y>X≧Z.
