Description of the Related Art As disclosed in Japanese Patent Application Laid-Open No. 1-299752, etc., it is necessary to keep the molten metal supplied in the cavity so that it does not solidify before being pressurized by a pressurizer. This is solved by applying a powdery heat insulating agent to the surface of the. Further, as a measure for preventing the supplied molten metal from being clogged at the portion from the molten metal supply port of the molten metal supply means to the molten metal spout part, the applicant of the present application previously proposed a casting mold apparatus as shown in FIG. Proposed (see Japanese Patent Laid-Open No. 6-15860).

まう不具合があった。However, in this casting mold apparatus, the regular product h cast in the cavity and the solidified product i which is not the product formed by the solidified product forming runner f are simultaneously advanced. It will be cast. Therefore, when the molten metal in the cavity is pressed, the product h is crushed by the heat-insulating layer of the powdery heat insulating agent and the molten metal comes into contact with the mold, so that it solidifies in a short time as in normal die casting. Since the pressure is not applied to the solidified product i from the original, the cooling rate becomes slow because the heat insulating layer formed by the powdery heat insulating agent remains formed between the mold and the molten metal. Hot water outlet b '
Since it is in the vicinity of and is higher in temperature than other parts, it takes time to solidify, and as a result, the timing of mold opening is the solidified product i.
However, there was a problem that the casting cycle was lengthened by the solidification time and the productivity was worse than that of ordinary die casting.

定することが好ましい。A molten metal return passage 40 is formed on the inner peripheral surface of the pressure sleeve 12 so that a part of the molten metal can return to the molten metal inlet 20 while the pressure element 8 is being pressed forward. This time,
The depth of the molten metal return passage 40 is cooled by contacting the side surface of the pressurizer 8 with the molten metal present in the molten metal return passage 40 during the pressurization and advance of the pressurizer 8, and the solid-liquid coexisting state (solid The volume ratio is set to 1 to 99%), and the distance (L) from the upper end of the molten metal return passage 40 to the upper end surface of the flange 12a of the pressure sleeve 12 is set.
Is adjusted to the pressurization volume of the smallest product to be cast, and when the volume of the product to be cast is small, the pressurization advance speed of the pressurizer 8 is increased to increase the molten metal in the molten metal return passage 40. To lower the solid phase ratio so that the viscosity does not rise,
When the volume of the product to be cast is large, the pressurizing advancing speed of the pressurizer 8 is increased so that the pressurizing advancing speed of the pressurizer 8 is slowed to increase the solid fraction of the molten metal in the molten metal return passage 40 to increase the viscosity. It is preferable that the solid phase ratio of the molten metal in the molten metal return passage 40 be adjusted by changing the value in accordance with the volume of the product to be cast.

可能となる。Then, when the pressurizer 8 is moved up toward the sprue 7 side of the cavity 5, a part of the melt in the pressurizing sleeve 5 passes through the melt return passage 40 and the melt inlet 2
0, and after the tip of the pressurizer 8 has passed the upper end of the molten metal return passage 40, the cavity 5 is passed through the molten metal in the sprue part 7.
Pressure is applied to the molten metal inside to cast a proper product. That is, when the volume of the product to be cast is small and the pressurizing volume at the time of casting is small, when the pressurizer 8 pushes up the molten metal in the sprue part 7, relatively high pressure is applied to the molten metal from the initial stage, and the molten metal is Through the molten metal return passage 40, the molten metal inlet 20
Therefore, the molten metal in the cavity 5 is not pressurized more than the resistance of the molten metal return, and the molten metal until the pressurizer 8 passes the upper end surface of the flange 12a of the pressure sleeve 12 is set as the pressurized volume of the cast product. Therefore, as a result, the tip portion of the pressurizer 8 can be reliably advanced to a position above the upper end of the flange 12a of the pressurizing sleeve 12, and conversely, the volume of the product to be cast is large and the pressurizing volume at the time of casting is large. If it is large, presser 8
Since the pressure received by the molten metal during the advancing of the molten metal does not become large even if the pressurizer 8 considerably advances, most of the molten metal present in the molten metal return passage 40 does not return to the molten metal inlet 20 and flows from the spout 7 into the cavity 5. That is, it is possible to sufficiently supply the molten metal corresponding to the volume change during casting. Such control can be made more delicately by changing the pressurizing forward speed of the pressurizer 8 according to the volume of the product to be cast and adjusting the solid phase ratio of the molten metal in the molten metal return passage 40. .

くなるようなことがなくなる。Therefore, it is possible to always set the final advancement position of the pressurizer to a position above the upper end face of the flange of the pressure sleeve and below the advancement limit of the pressurizer regardless of the change in volume of the product to be cast. Therefore, regardless of the volume of the product to be cast, it is possible to sufficiently supply and pressurize the molten metal for the volume change at the time of casting, and to add pressure without changing the pressurizer and the pressure sleeve according to the volume of the product to be cast. Since the tip portion of the indenter can surely reach the position above the upper end of the flange of the pressure sleeve, it is possible to prevent a part of the cast product from being inside the pressure sleeve and being unable to be taken out from the cavity.

The push pin 34 is faced inside and the hook pin 33 is projected. After that, the molten metal is directly introduced into the pressure sleeve 12 through the molten metal inlet 6a of the molten metal supply means 6 through the molten metal inlet 20 of the pressure sleeve 12, and the molten metal is introduced from the spout portion 7 into the cavity 5
Fill the inside with molten metal. When the pressurizing cylinder 9 is operated to raise the pressurizer 8 toward the gate 7 side of the cavity 5, the molten metal in the cavity 5 passes through the melt in the gate 7 as the pressurizer 8 rises. Pressurized, the molten metal in the cavity 5 is solidified in that state, and the product is cast.
