[0030] Among them, piston 31 is arranged on connecting piece 3, casting cavity 21 is formed in mold cavity 2, piston 31 is attached to casting cavity 21 and moves along casting cavity 21. Walking wheel 4 rolls along the moving direction of the casting mold mechanism.

[0031] A conveying support is arranged along the moving direction of the casting mold mechanism, and a plurality of casting mold mechanisms are arranged on the conveying support. The walking wheel 4 rolls along the conveying support to move the casting mold mechanism between the press and the crucible. The crucible is located below the press, the mechanical arm places the casting mold mechanism on the crucible, the crucible is filled with inert gas, the aluminum liquid in the crucible enters the mold cavity 2, the press presses the connecting piece 3, the connecting piece 3 extrudes the aluminum liquid from above, and the aluminum liquid is solidified and formed. After the press resets, the mechanical arm removes the casting mold mechanism from the crucible for demolding.

[0032] Mold cavity 2 is arranged at the lower end of support 1 in the up-down direction, and to improve the casting efficiency of the casting mold mechanism, mold cavity 2 can be provided with multiple. Connecting piece 3 is arranged at the upper end of support 1 in the up-down direction. Piston 31 is arranged at the lower end of connecting piece 3. Piston 31 is arranged in casting cavity 21, and the outer surface of piston 31 is attached to the inner surface of casting cavity 21.

[0033] Aluminum liquid is injected into casting cavity 21, the press presses connecting piece 3, connecting piece 3 pushes piston 31 to move downward along casting cavity 21, and piston 31 presses the aluminum liquid to form. After the aluminum liquid is solidified and formed, the press resets, and connecting piece 3 pulls piston 31 to move upward and reset.

[0034] By rolling walking wheel 4 along the moving direction of the casting mold mechanism, the casting mold mechanism can be moved to the crucible for casting. After casting is completed, the casting mold mechanism can be removed, the next group of casting mold mechanisms can be moved to the crucible for casting, and the continuous casting of aluminum liquid can be carried out in this way. The casting efficiency is improved.

[0035] Support 1 includes upper plate 11, lower plate 12 and column 13. Column 13 is arranged between upper plate 11 and lower plate 12.

[0036] The upper plate 11 and the lower plate 12 are horizontally arranged. The upper end of the column 13 is connected to the upper plate 11, and the lower end of the column 13 is connected to the lower plate 12.

[0037] The lower plate 12 is provided with a bushing 18 in the up-down direction, the mold cavity 2 passes through and is arranged in the bushing 18, and the mold cavity 2 moves up and down in the bushing 18. Different mold cavities 2 can be replaced in the bushing 18 to cast different shapes of castings.

[0038] A flange 23 is arranged around the lower end of the mold cavity 2, and the flange 23 is fixedly connected to the liquid outlet of the crucible by bolts. The casting mold mechanism can be moved by unscrewing the bolts.

[0039] When the mold cavity 2 moves up to the limit position, the flange 23 abuts against the bushing 18, and the upper surface of the flange 23 contacts the lower surface of the bushing 18, thereby limiting the mold cavity 2 from continuing to move upward and preventing the mold cavity 2 from being separated from the bushing 18.

[0040] An upper cover 22 is arranged on the mold cavity 2 to seal one end of the casting cavity 21. The casting cavity 21 penetrates the mold cavity 2 in the up-down direction, the lower end of the casting cavity 21 flows into the aluminum liquid, and the upper end of the casting cavity 21 is sealed by the upper cover 22.

[0041] When the connecting member 3 pulls the piston 31 to move upward along the casting cavity 21 to the limit position, the piston 31 contacts the upper cover 22, and the upper surface of the piston 31 contacts the lower surface of the upper cover 22, thereby limiting the piston 31 from continuing to move upward and preventing the piston 31 from being separated from the casting cavity 21.

[0042] The diameter of the upper cover 22 is greater than the diameter of the mold cavity 2. When the mold cavity 2 moves downward to the limit position, the upper cover 22 contacts the upper end of the bushing 18, thereby limiting the mold cavity 2 from continuing to move downward and preventing the mold cavity 2 from being separated from the bushing 18.

[0043] First springs 32 are respectively arranged on the two sides of the upper plate 11 on the connecting member 3. The first springs 32 respectively elastically push the connecting member 3 upward and the mold cavity 2 downward.

The upper end of the upper first spring 32 abuts against the mushroom head 33, and the lower end of the upper first spring 32 abuts against the upper surface of the upper plate 11. The upper end of the lower first spring 32 abuts against the lower surface of the upper plate 11, and the lower end of the lower first spring 32 abuts against the upper surface of the upper cover 22.

[0045] The first spring 32 located above provides an upward elastic pushing force for the connecting piece 3, and the first spring 32 located below provides a downward elastic pushing force for the mold cavity 2, so that hard contact of the connecting piece 3, the mold cavity 2 and the piston 31 during movement is avoided, and collision damage of the casting mold mechanism is avoided.

The second spring 42 is sleeved on the walking rod 41, the upper end of the second spring 42 abuts against the upper end of the walking rod 41, and the lower end of the second spring 42 abuts against the upper plate 11. The second spring 42 pushes the walking rod 41 upward. The walking wheel 4 is rotationally arranged at the upper end of the walking rod 41.

[0047] The second spring 42 forms an elastic pushing force on the walking rod 41, so that the walking wheel 4 rolls along the conveying support and is not in hard contact, thereby playing a shock-absorbing role.

[0048] The fixed rod 14 is arranged on the support 1 and is arranged at the middle position of the upper plate 11 in the up-down direction. The electromagnetic moving plate 5 is slidably arranged on the fixed rod 14. The third spring 15 is sleeved on the fixed rod 14, the upper end of the third spring 15 abuts against the lower surface of the electromagnetic moving plate 5, and the lower end of the third spring 15 abuts against the upper surface of the upper plate 11. The third spring 15 elastically supports the electromagnetic moving plate 5, and the third spring 15 forms an upward pushing force on the electromagnetic moving plate 5.

[0049] When the clamping end of the mechanical arm approaches the casting mold mechanism, the clamping end of the mechanical arm magnetically attracts the electromagnetic moving plate 5, and the mechanical arm can move the casting mold mechanism. Through the elastic pushing force of the third spring 15 on the electromagnetic moving plate 5, hard contact of the electromagnetic moving plate 5 and the clamping end of the mechanical arm is avoided, and collision of the electromagnetic moving plate 5 and the clamping end of the mechanical arm is avoided.

Figure 2 An enlarged structure diagram at A in the middle is shown. Figure 2 And Figure 3 As shown in the drawings, the casting mold mechanism further comprises a support plate 6. The mounting shaft 16 is arranged on the support 1 and is horizontally arranged. The support plates 6 are rotationally arranged along the mounting shaft 16 and cross each other. For example, the support plates 6 are two groups. The one group of support plates 6 is formed with a notch, and the other group of support plates 6 is formed with a notch, and the two groups of support plates 6 are arranged in the notches to cross each other. When the one group of support plates 6 is rotationally stressed, the other group of support plates 6 is pressed downward by the edges of the notches to rotate.

[0052] The fourth spring 17 is arranged on the mounting shaft 16 and pushes the support plates 6 to support the electromagnetic moving plate 5.

[0053] The third spring 15 only forms elastic pushing force on the middle position of the electromagnetic moving plate 5, when the clamping end of the mechanical arm contacts the electromagnetic moving plate 5, the left and right ends of the electromagnetic moving plate 5 will swing to a certain extent, and the position of the electromagnetic moving plate 5 attracted by the clamping end of the mechanical arm will be offset.

[0054] Under the elastic pushing force of the fourth spring 17, the upper ends of the two groups of support plates 6 are close to each other, the upper ends of the support plates 6 contact the lower surface of the electromagnetic moving plate 5, and the two groups of support plates 6 form support on the left and right ends of the electromagnetic moving plate 5.
