Field of the Invention The present invention relates to a method of forming a metal, and more particularly, to lowering the temperature of a molten metal injected into a die casting sleeve by bringing the molten metal into contact with a cooling jig to lower the temperature. The present invention relates to a method for forming a molten metal, which is formed by immediately injecting and molding after the temperature is equal to or higher than the liquidus temperature or lower than the liquidus temperature.

Compared with the conventional casting method, it has fewer casting defects and segregation, has a uniform metal structure, has a long mold life, and has a very advantageous feature in mass production with a short molding cycle. It is a technology that is receiving attention. In these molding methods, molding is usually performed at a liquid phase ratio of 40% to 60%. On the other hand, the liquid is injected into the mold cavity (cavity) at a low speed (about 0.1 m / s in chip speed),
2. Description of the Related Art A squeeze casting method is known as a casting method for forming a high-quality product that can be heat-treated by molding under high pressure with few casting defects.

形のスクイズ鋳造において認められる熱間割れと異なる
割れが凝固完了後に発生することがある。However, in the thixocast method described above, the liquid phase is once solidified in order to perform semi-solid molding, and a billet having a predetermined metallographic structure is obtained. It is necessary to raise the temperature up to this point, which increases the cost compared to the conventional casting method. In addition, in the rheocasting method, since a melt containing a spherical primary crystal is continuously generated and supplied, it is more advantageous in terms of cost and energy than thixocast, but a metal raw material consisting of a spherical structure and a liquid phase is used. The interlocking of equipment between the machine to manufacture and the casting machine to manufacture the final product is complicated. For this reason, it is desired that a metal slurry having a predetermined liquid phase ratio be prepared each time in forming each shot. However, it is not always easy to obtain a slurry having a uniform temperature distribution for each shot, and the equipment becomes complicated. In addition, in semi-solid forming of a magnesium alloy, a liquid phase ratio generally used is 40 to 60%.
In some cases, depending on the product shape (for example, a cylindrical casting), cracks different from the hot cracks observed in squeeze casting in liquid molding may occur after solidification is completed.

ながらない。[0004] In addition, the cast product formed by the squeeze casting method described above is often not necessarily short in solidification time because the wall thickness is large and the biscuit (metal other than the product on the gate side) is large. , Long cycle. For this reason, we want to keep the temperature of the molten metal held for pouring into the injection sleeve close to the liquidus temperature, but this causes the molten metal to solidify and adhere to the hot water supply jig such as a ladle. Driving may not be possible. In addition, when the high-temperature molten metal is poured into the injection sleeve and then waits for a decrease in the temperature of the molten metal, solidification proceeds from the wall surface of the sleeve inside the sleeve, and a uniform temperature decrease is not always expected. It takes time and does not lead to the improvement of shortening the casting cycle.

を目的としている。[0005] In high-pressure casting, columnar crystals are formed on the surface of the casting, and as a result, a large amount of segregation occurs in the center of the product, resulting in a decrease in mechanical properties and cracks in corners of the product. Sometimes. Therefore, it may be desirable to add a refiner to prevent these phenomena. Therefore, for example, in an aluminum alloy, Al
-A fine grain is added by adding a small amount of a Ti-B mother alloy, and C2C6 and CaCN2 are added in a magnesium alloy. However, unlike a batch furnace, in a melting furnace that is continuously supplied, the operation of adding the above-mentioned refining agent is cumbersome, or the effect of the refining ability is small, or even if the duration is short. There are difficulties. The present invention focuses on the problems of the conventional methods described above,
It is an object of the present invention to provide a method in which a molten metal is brought to a low temperature state very easily and a pressure is immediately formed without using a complicated method.

It is made of metal or ceramic, and may be either a vertical sleeve or a horizontal sleeve.
The vertical sleeve has better heat retention, and a good molded product can be obtained during injection molding. Further, "pour into a sleeve and immediately inject and press-mold" means that the mold cavity is filled with molten metal within 10 seconds, preferably within 5 seconds after completion of pouring. When the injection is performed for more than 10 seconds after the completion of the pouring, the temperature of the molten metal in contact with the side wall and the bottom of the sleeve is rapidly reduced to form a solidified layer, so that the injection is performed within 10 seconds.
Since the molten metal in the sleeve immediately before injection is almost in the liquid phase, the metal structure after injection molding is brought into contact with a cooling jig (a), and the temperature of the molten metal immediately after pouring into the sleeve is changed to the liquid phase of the molten metal. When the temperature is lower than the linear temperature, the structure in which the primary crystals are presumed to be granular or petal before injection molding and the structure in which the liquid phase before injection is solidified (the eutectic structure and the dendritic primary crystal (B) When the temperature of the molten metal immediately after being brought into contact with the cooling jig and poured into the sleeve is higher than the liquidus temperature of the molten metal, it is composed of a dendritic primary crystal structure.

It means the temperature of the center metal in the sleeve after pouring is completed.
Further, if the degree of superheat exceeds 25 ° C., it cannot be said that a low-temperature molten metal is obtained and pressure molding is performed immediately, and the effect of shortening the solidification time is small. The degree of superheat with respect to the liquidus line is less than 25 ° C. Furthermore, the solid phase ratio in a semi-liquid state lower than the liquidus temperature is set to less than 15% because when the solid phase ratio exceeds 15%, a solidified layer is formed on the inner wall surface of the sleeve in the die casting sleeve. , Preferably 10% or less, more preferably 5% or less.

In Comparative Example 7, since the holding time from the completion of pouring to injection was long and the solid phase ratio was large, a solidified layer was formed in the sleeve, so that an uneven metal structure was observed in the molded product. . In Comparative Examples 8 to 10, since the molten metal was poured without using the cooling plate, the temperature in the sleeve after the completion of the molten metal was 30 ° C. or more, and the shortening of the solidification time could not be expected much. Moreover, in Comparative Example 8, eutectic segregation was observed at the center of the molded article, and in Comparative Examples 9 and 10, hot cracking occurred at the corners of the molded article.
