[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0020] A double-mold mold for metal casting, comprising a base 1, four positioning rods 2 are symmetrically fixedly installed on the upper surface of the base 1, a top plate 3 is fixedly installed on the top of the positioning rods 2, a movable carrier frame 4 is slidably installed between the four positioning rods 2, an upper mold platform 5 is rotatably installed in the movable carrier frame 4, an upper mold cavity A51 and an upper mold cavity B52 are respectively opened on the upper and lower surfaces of the upper mold platform 5, an exhaust hole 53 and an injection port 54 are connected between the upper mold cavity A51 and the upper mold cavity B52, a lower mold platform 6 is rotatably installed in the base 1, a lower mold cavity A61 and a lower mold cavity B62 are respectively opened on the upper and lower surfaces of the lower mold platform 6, the upper mold cavity A51 is used in conjunction with the lower mold cavity A61, the upper mold cavity B52 is used in conjunction with the lower mold cavity B62, and locking devices 7 are provided between the upper mold platform 5 and the movable carrier frame 4 and between the lower mold platform 6 and the base 1;

[0021] It should be noted that, combined with Figure 4 and Figure 5 As shown, the left and right surfaces of the movable frame 4 and the left and right surfaces of the upper end of the base 1 are symmetrically penetrated with through openings 8, and the upper surface of the movable frame 4 and the upper surface of the base 1 are symmetrically opened with a plurality of threaded holes 9, such as Figure 5 As shown, the left and right surfaces of the upper die table 5 and the left and right surfaces of the lower die table 6 are symmetrically provided with locking holes 10, and the locking device 7 comprises an L-shaped plate 71, and the upper surface of the L-shaped plate 71 is symmetrically penetrated with mounting holes 711, and the inner side of the L-shaped plate 71 is symmetrically fixed with locking rods 72, and the locking rods 72 penetrate the corresponding through openings 8 and are inserted into the corresponding locking holes 10, and bolts 712 are threadedly installed between the mounting holes 711 and the corresponding threaded holes 9;

[0022] When in use, according to the use requirements, the bolts 712 are unscrewed, the L-shaped plate 71 is removed, the upper die table 5 and the lower die table 6 are turned over, so that the upper die cavity A51 is opposite to the lower die cavity A61 or the upper die cavity B52 is opposite to the lower die cavity B62. After adjustment, the locking rod 72 of the upper L-shaped plate 71 is inserted into the locking hole 10 of the upper die table 5 through the through hole 8 on the movable carrier frame 4, and then, the bolt 712 is installed between the mounting hole 711 of the upper L-shaped plate 71 and the threaded hole 9 of the movable carrier frame 4 to fix the upper die table 5 and the movable carrier frame 4. The operation method is to fix the lower mold platform 6 and the base 1 by using the locking device 7 at the lower end, then buckle the upper mold platform 5 and the lower mold platform 6 together to form a casting cavity, and pour the molten metal into the mold cavity formed by the buckling of the upper mold platform 5 and the lower mold platform 6 through the injection port 54. After the molten metal is cooled, move the upper mold platform 5 upward to remove the cast metal casting. Compared with the prior art, the mold can choose to use different mold cavities to cast corresponding types of metal castings according to the use requirements, and can meet the demand of using the same mold to cast two types of metal castings.

[0023] In addition, when the upper mold platform 5 and the lower mold platform 6 are buckled together to form a casting cavity, it is considered that if the molten metal is directly poured through the injection port 54, once an operation error occurs, part of the molten metal may be scattered and remain in the upper mold cavity A51 or the upper mold cavity B52 to be used, which is difficult to clean. Figure 3 As shown, a liquid guide tube 55 is threadedly installed in the injection port 54, and the liquid inlet end of the liquid guide tube 55 is set at the position of the upper mold platform 5 in principle. When choosing to use different mold cavities, first unscrew the liquid guide tube 55, and after adjusting the position of the upper mold platform 5 according to the use requirements, install the liquid guide tube 55 in the injection port 54 for use. Under the condition that it does not affect the use, the liquid guide tube 55 can be used to pour the molten metal from the position of the upper mold platform 5 in principle, which can effectively prevent the molten metal from scattering and remaining in the upper mold cavity A51 or the upper mold cavity B52 to be used above.

[0024] In addition, in order to prevent the liquid guide tube 55 from affecting the flatness of the liquid injection cavity (the cavity formed by the upper mold platform 5 and the lower mold platform 6 after buckling), affecting the metal casting prototype, such as Figure 3 As shown, a positioning ring 551 is fixedly installed on the outer surface of a liquid guide tube 55 threadedly installed in the injection port 54. When the positioning ring 551 is fitted into the upper mold cavity A51 or the upper mold cavity B52, the discharge end of the liquid guide tube 55 maintains a horizontal position with the inner wall of the injection mold cavity to avoid affecting the metal casting prototype and ensure the quality of metal casting.

[0025] Finally, in order to facilitate the upper die table 5 to move up and down, as shown in FIG. Figure 1 or Figure 2As shown, two hydraulic telescopic columns 31 are symmetrically fixedly installed between the lower surface of the top plate 3 and the upper surface of the movable frame 4. The movable frame 4 is driven up and down by the hydraulic telescopic columns 31 to drive the upper mold platform 5 to move up and down, making mold opening more convenient and quick.
