うになつている。 In general, a die casting machine, as shown in FIG. 4. A movable mold 5 and a movable frame drive device 6 are fixed to the movable frame 4 and move into and out of contact with the fixed mold 3,
After the two molds 3 and 5 are brought into close contact with each other, the injection molding cylinder 7 provided on the fixed frame 2 is moved as shown in FIG. 2a.
Molten metal 10 is supplied from the hot water supply port 9 through the hot water pump 8.
, the cylinder 7
Molten metal is filled into the molding cavity 16 of each mold via the hot water supply path 12, biscuit 13, runner 14 and gate 15 (see FIG. 2d), and casting is performed.

ンナ１４及びゲート１５で成形されるカスが多
く、生産効率が悪いといつた問題があつた。 By the way, in the casting machine described above, since the bottom surface 12a of the cylindrical hot water supply passage 12 in the cylinder 7 is formed horizontally, the molten metal 10 accumulates in the lower half of the hot water supply passage 12, while air remains in the upper half. By driving the piston 11, at low speed, the molten metal 10 begins to be press-fitted into the cavity 16 with air remaining in the cylinder 7, as shown in FIG. It is press-fitted into the cavity 16 with the air inside the cylinder 7 mixed therein. Therefore, there is a high possibility that shrinkage cavities and the like will occur in the products 17 and 18 as shown in FIGS. 3 and 4, resulting in problems such as deterioration of quality. For this reason,
When the residual molten metal 10 in the biscuit 13, runner 14 and gate 15 is reduced, the molten metal 10 solidifies faster than the molten metal 10 in the cavity 16, and the air mixed in the molten metal 10 in the biscuit 13 at the time of solidification is removed. It moves into the molten metal 10 in the cavity 16, and the products 17 and 18 are likely to have sink marks and sink cavities. Therefore, it is necessary to increase the amount of molten metal 10 remaining in the biscuit 13 etc. to a certain extent so that the molten metal 10 in the cavity 16 solidifies faster than the molten metal 10. There was a problem that there was a lot of molding waste, which caused poor production efficiency.

造することができないといつた問題があつた。 Furthermore, in the above casting machine, since the bottom surface 12a of the hot water supply path 12 is horizontal as described above, the cavity 16 is connected to the biscuit 13 at the tip of the hot water supply path 12.
In the case where the molten metal 10 is supplied from the molten metal inlet 9 to the molten metal supply path 12, the molten metal 10 is press-fitted from the biscuit 13 through the runner 14 and the gate 15 into the lower cavity by driving the piston 11. Before the process, the molten metal 10 flows in and begins to solidify, causing uneven solidification in the product. Therefore, as shown in FIGS. 3 and 4, the cavity can only be provided above the biscuit 13 at the tip of the hot water supply path. There was a problem in that it was not possible to cast a material (see Figure 11).

ている。 The die casting machine according to the present invention produces a molded product by injecting molten metal pushed out by an injection piston of an injection molding cylinder from a biscuit through a gate into a molding cavity formed by a pair of closed molds. In the molten metal feed path where the molten metal supplied from the molten metal feed port into the injection molding cylinder is pushed out to the biscuit by the injection piston, there is a line along a direction intersecting the axial direction of the molten metal feed path. A molten metal damming member is provided that can be freely accessed and removed.
The dam is characterized in that the damming member prevents the molten metal from flowing into the biscuit at its entry position into the hot water supply path, while the exit position of the damming member outside the hot water supply path does not prevent the molten metal from flowing into the biscuit. It is said that

-G may be inclined with respect to the horizontal plane. Furthermore, as shown in FIGS. 16 to 18, the injection molding cylinder 23 may be tilted to the fixed frame 24 with the support of the support frame 48 so that the bottom surface of the hot water supply path 44 gradually rises toward the tip. . At this time, the molten metal 3 supplied into the hot water supply path 44
Of 7, since the amount of molten metal at the tip on the biscuit side is small, the temperature of the molten metal at the tip decreases before injection molding.
Although a part of the molten metal 3 in the hot water supply path 44 may solidify, there is a risk that the degree of melt mixing with other hot metal after injection molding may become uneven.
By providing the molten metal 37 near the tip of the biscuit side of the molten metal 37, when the molten metal 37 is supplied to the hot water supply path 44, the molten metal 3
The amount of hot water at the tip on the biscuit side of No. 7 does not decrease, and the degree of melting and mixing does not become uneven. In this way, if the hot water supply path 44 is inclined with respect to the horizontal plane, when the molten metal 37 in the hot water supply path 44 is press-fitted into the cavity 50, the air in the hot water supply path 44 flows into the cavity 50 before the molten metal 37. The molten metal 37 is then discharged from the cavity through the air vent, and then the molten metal 37 is press-fitted, which reduces the amount of air that gets mixed into the molten metal 37, making it less likely that sink marks or shrinkage cavities will occur in the product, improving quality. . Note that the structure shown in Figs. 16 and 17 and the structure shown in Fig. 18
Regarding the supply of the molten metal 37 into the cylinder 23 and the driving operation of the piston 23a in this embodiment shown in FIGS.
Since it is the same as that shown in ~d, the explanation will be omitted by attaching the same reference numerals to the same parts. Furthermore, the product has biscuits 4 as shown in FIG.
It is not limited to the one cast with a radial cavity centered on the biscuit 9, but also the one cast with a cavity 76 surrounding the biscuit 49 at regular intervals as shown in FIGS. 19a and 19b. But that's fine.
