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 is injected into the mold cavity by moving a plunger member into the molten metal in the holding furnace and raising the molten metal head. However, since the plunger member is inserted into the high-temperature molten metal, the plunger member may be deformed by the heat of the molten metal, or foreign matter in the molten metal may adhere to the plunger member, causing the volume of the plunger member to change and the pressurizing head to be closed. There will be excess and deficiency. This has caused variations in the strength of the cast product or casting defects.

に備える。 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 cooling water is circulated through the space between the molten metal cylinder 8 and the protective cover 11, and the lower mold 14 and the upper mold 1
In the state shown in FIG. 1 in which the molds 5 and 5 are matched, the cylinder 10 is retracted, and the molten metal container 7 and the molten metal cylinder 8 are
The molten metal cylinder 8 is stretched upward until the molten metal level in the mold cavity 13a is higher than the molten metal head (the top end of the cavity 13a), and the molten metal spreading laterally is pushed out in the vertical direction. The level is raised and the molten metal is poured into the mold cavity 13a through the molten metal pouring hole 5 and the molten metal injection hole 1.
The molten metal is injected through the mold cavity 13a, and the state is maintained for a certain period of time to apply pressure to the molten metal in the mold cavity 13a, so that the molten metal spreads to every corner of the mold cavity 13a. During this time, the molten metal in the mold cavity 13a is not moved to a position higher than the uppermost end of the cavity, so that the state in which pressure is applied from below is maintained. After a predetermined period of time has elapsed, when the molten metal in the mold cavity 13a solidifies, the cylinder 12 is extended to bend 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 that of the mold cavity 13a. The molten metal in the mold cavity 13a is separated from the molten metal in the molten metal container 7. Next, by retracting the mold matching cylinder 17, the upper mold 15 holding the cast product is raised and separated from the lower mold 14, and then the space between the lower mold 14 and the upper mold 15 is removed. When the product ejecting device (not shown) enters and the upper mold 15 is raised by the retracting operation of the mold matching cylinder 17, the ejector pin 22 comes into contact with the stopper pin 24 and protrudes into the mold cavity 13a. The cast product held in the upper mold 15 is pushed out onto the upper surface of the product take-out device by the push-out pin 22 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.

寄与する効果は著大である。 As is clear from the above description, according to the present invention, the molten metal is injected into the mold cavity by moving the mold cavity up and down in a flexible manner between the upper position and the lower position. , the molten metal is always pressurized and injected into the mold cavity at a stable pressure, and as a result, it has the effect of obtaining a cast product with no dispersion and good casting defects, and the effect that contributes to this type of industry is significant. It's large.
