ッドの過不足が生じる。このため、鋳造品の強度のばら
付、或いは鋳造欠陥を生じていた。Conventionally, in low-pressure casting, the molten metal in the holding furnace circle is injected into the mold cavity by inserting a plunger member into the molten metal in the holding furnace and raising the molten metal head. However, because this plunger part enters the high-temperature molten metal, the plunger part may be deformed by the heat of the molten metal, or foreign matter in the molten metal may adhere to the plunger part, causing pressure to increase due to a change in the volume of the plunger part. There will be an excess or deficiency of heads. This has caused variations in the strength of the cast product or casting defects.
本発明はこれらの問題点を解決することを目的とするも

備える。Next, the operation of the device configured as described above will be explained. A predetermined amount of molten metal is stored in the molten metal container (7) and the molten metal cylinder (8)
Cooling water is circulated through the space between the cylinder (10) and the protective cover (11), and the cylinder (10) operates to contract and stretch the molten metal cylinder (8) upward until the molten metal level in the molten metal container (7) and molten metal cylinder (8) is higher than the molten metal head of the mold cavity (13a). The molten metal is injected into the mold cavity (13a) through the molten metal pouring hole (5) and the molten metal injection hole (14a), and the state is maintained for a certain period of time to apply pressure to the molten metal in the mold cavity (13a). Make sure that the molten metal spreads to every corner inside the mold cavity (13a). After a predetermined period of time has elapsed, when the molten metal in the mold cavity (13a) solidifies, the cylinder (12) is extended.
The mold cavity (13a) is formed by bending the molten metal cylinder (8) until the molten metal level in the molten metal container (7) and the molten metal cylinder (8) is lower than the mold cavity (13a).
The molten metal inside is separated from the molten metal in the molten metal container (7). Next, by retracting the mold matching cylinder (17), the mold (15) that held the cast product is raised to the lower mold (14).
), then a product ejecting device (not shown) is inserted into the space between the lower mold (14) and the upper mold (15), and the mold fitting cylinder (17) is then contracted. When the upper mold (15) is raised by the pulling action, the ejector pin (22) comes into contact with the stopper pin (24) and protrudes into the mold cavity (13a), and the upper mold (15)
The cast product held in 5) is pushed out by the push-out pin (22) to the two sides of the product take-out device and taken out to the outside. Thereafter, a predetermined amount of molten metal is replenished into the molten metal container (7) via the chute member (25) and the molten metal cylinder (8) in preparation for the next operation.
