It relates to a casting method for preventing. "Prior Art" For example, in the horizontal stack casting method disclosed in Japanese Patent Publication No. 57-14251, the turbulence of the molten metal flow is reduced by designing the runners provided in the mold and the cross-sectional area of the weir. Although it is considered that the molten metal fills the product cavity in sequence, the molten metal 30 may be postponed in the continuous runner depending on the shape of the product. For example, at a portion near the pouring port 6 where the distance X between the adjacent cavities 25, 25 is short, the molten metal flowing at the start of casting has a strong momentum, and therefore has a drawback that it tends to be postponed in the runner. [Problems to be Solved by the Invention] As described above, in the conventional horizontal stack casting method, as a result of the advance of the molten metal in the runway, the flow of the molten metal into the cavity is disturbed unevenly, and as a result, the quality of the cast product is improved. It was deteriorated and had a defect that the yield of cast products was poor.

道２を一定間隔毎に閉鎖して区劃する。The present invention aims to prevent the molten metal from being postponed and to eliminate the defects of cast products. "Means for Solving Problems" The present invention provides a step of forming a mold row by horizontally adhering a plurality of molds, abutting the contact plates on both ends and tightening with long bolts, and forming the mold row. Forming a storage chamber at regular intervals in the middle of the connection runners in which the runners connected to the cavity are connected to each other; And a step of forming a pouring port by connecting to the passage, and a hot-water stopper formed of a material that is melted by the high heat of the molten metal by previously determining the thickness based on the volume of the cavity and the cross-sectional area of the connecting runner. A structure including a step of dividing the connection runner by inserting it into the storage chamber is a means for solving the above problems. "Working" In the middle of the connecting runner, which connects the molds horizontally adjacent to each other in the mold and connects the runners to each other, a hot water stopper that disappears due to the high heat of the molten metal is provided at predetermined intervals. The hot-water stopper prevents the molten metal from being advanced in the runway, and sequentially fills the molten metal in each cavity to improve the yield of cast products. "Examples" Explaining examples of the present invention with reference to the drawings, 1 is a mold used for shell mold, green mold casting method, gas mold, etc., which is solidified by adding an additive such as a range, The cavities 5 are respectively formed below the connection runners 2 in which the runners provided in the horizontal direction are aligned and connected to each other. This connection runway 2
A storage chamber 8 is formed in the middle of the connection runway in a direction orthogonal to the connection runner, and hot water stoppers 9 are inserted into the storage chamber 8 to close the connection runner 2 at regular intervals. To do.

Reference numeral 11 designates a plurality of casting molds 1 and 1 horizontally adjacent to each other, and a row of casting molds formed by tightening contact plates 12 and 12 abutting on both left and right ends with long bolts (not shown) or the like. Connected runners 2 formed by connecting the provided runners to each other are connected to each other,
While attaching the hot water stopper 9 in the middle of the step, the plugs 13 are fitted to both ends of the connecting runner 2.

When the pouring port 6 is connected to one end of the connection runner 2 provided inside and the molten metal is poured from this pouring port 6, especially in the portion close to the pouring port 6, the molten metal flowing at the start of casting Due to the strong momentum, the molten metal is postponed to the end of the connecting runway 2. In addition, when the melt stop body 9 provided in the middle of the connection runway prevents the molten metal from being advanced and the flow of the melt slows down, the melts gradually enter into the cavity in the front part of the melt stop, and the inside of the cavity is melted. By the time it is full,
The molten metal enters the part of the molten metal stopper and is similarly supplied into the cavity in the front part of the molten metal stopper, and the molten metal work is performed by repeating this.

A molten metal stopper 9 is attached in the middle of the passage 2 to prevent the molten metal from flowing until at least the cavity 5 located in the front portion of the molten metal stopper 9 is completely filled with the molten metal.

段と向上させることが出来る利点を有するものである。In addition, the hot water stopper 9 interposed in the middle of the connection runner of the mold rows 11 connected in the longitudinal direction of the mold rows 11 is formed so that an accommodation chamber 18 is formed at the end face of each adjacent mold and accommodated therein. In that case, the storage chamber 18 can be formed more easily than in the embodiment shown in FIG. 1 (third embodiment).
Figure). [Advantages of the Invention] The present invention provides a pouring spout by providing a hot water stopper for temporarily stopping the molten metal in a connecting runner provided inside a mold row integrally formed by connecting same-shaped molds in series. Since the molten metal is sequentially supplied to the end of the mold row while filling the cavity from the side, it is possible to prevent the molten metal from being advanced. By preventing the advance of the molten metal and slowing down the flow of the molten metal, the contamination of impurities is prevented, and the deterioration of casting quality such as hot water balls, wrinkles, hot water boundaries, pinholes, blowholes, hardness defects, chills, etc. This has the advantage that it can be prevented and the yield of cast products can be further improved.
