[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Example 1, see Figures 1-7 This embodiment provides a mold for lightweight aluminum alloy conductor casting, including a cavity mold 1, mounting blocks 2 fixedly connected to both sides of the cavity mold 1, mounting rods 3 fixedly connected to the upper end of the mounting blocks 2, and a top plate 4 fixedly connected to the top of the mounting rods 3. A motor 51 is fixedly connected to the top of the top plate 4. A ratchet 52 is fixedly connected to the output end of the motor 51. A movable telescopic rod A53 is fixedly connected to the bottom of the ratchet 52. A transmission wheel A54 and a reciprocating screw 55 are rotatably connected to the bottom of the top plate 4. A transmission wheel B56 is fixedly sleeved on the outer wall of the reciprocating screw 55. A transmission belt A57 is wound around the outer walls of the transmission wheels A54 and B56. A moving column 58 is threadedly connected to the outer wall of the reciprocating screw 55. An extrusion die 59 is fixedly connected to the bottom of the moving column 58. A bevel gear A510 is fixedly connected to the bottom of the movable telescopic rod A53. A fixing block 511 is fixedly sleeved on the outer wall of the mounting rod 3. A bevel gear ring 512 is slidably connected to the upper side of the fixing block 511. An elastic telescopic rod B513 is fixedly connected to the bottom of the bevel gear ring 512. A roller 514 is provided at the bottom of the elastic telescopic rod B513. A connecting block A515 is fixedly sleeved on the outer wall of the elastic telescopic rod B513. A cutting blade 516 is fixedly connected to the upper end of the connecting block A515. An annular frame 517 is fixedly connected to the upper end of the mounting block 2. A notch 518 is opened on one side of the outer wall of the annular frame 517. A ratchet 521 is hinged to the inner wall of the transmission wheel A54.

[0028] A connecting plate A519 is fixedly connected to the side of the movable column 58, and the connecting plate A519 is fixedly sleeved on the outer wall of the movable telescopic rod A53. The upper end of the connecting plate A519 is fixedly connected to the movable telescopic rod B520, and the top of the movable telescopic rod B520 is fixedly connected to the bottom of the top plate 4.

[0029] A spring A is fixedly connected to the inner wall of the transmission wheel A54, and the other end of the spring A is fixedly connected to the pawl 521. This connection method enables the spring A to play an important connecting role between the transmission wheel A54 and the pawl 521. Whether the transmission wheel A54 moves or the pawl 521 is affected by external force, the spring A can effectively transmit force or buffer impact.

[0030] The bottom of the roller 514 is always in contact with the top surface of the annular frame 517. No matter how the roller 514 moves, its bottom will be firmly attached to the top surface of the annular frame 517, ensuring a stable and reliable connection between the two.

[0031] In practical use, the above equipment first needs to be preheated to 150-180 degrees Celsius. Then, the molten aluminum alloy is poured into the cavity mold 1. Next, the motor 51 is started to drive the ratchet 52 to rotate clockwise. The ratchet 52 will then drive the transmission wheel A54 to rotate synchronously through the pawl 521 inside the transmission wheel A54. The transmission wheel A54 drives the transmission wheel B56 and the reciprocating screw 55 to rotate through the transmission belt A57. This causes the moving column 58, which is threaded to the reciprocating screw 55, to move downward under the guidance of the movable telescopic rod B520, thereby pushing the extrusion mold 59 to extrude the aluminum alloy in the cavity mold 1, thus stopping the motor 51. During this process, the moving column 58 drives the movable telescopic rod A53 to move down synchronously through the connecting plate A519. The bevel gear A510 at the bottom of the movable telescopic rod A53 moves down and meshes with the bevel gear ring 512. After cooling and forming, the motor 51 drives the ratchet 52 to rotate counterclockwise, which in turn drives the bevel gear ring 512 to rotate. During the rotation, the bevel gear ring 512 drives the roller 514 to roll along the upper top surface of the annular frame 517 through the elastic telescopic rod B513. Since the roller 514 is always in contact with the annular frame 517, the roller 514 can slide out from the notch 518. Then the elastic telescopic rod B513 can extend upward, driving the connecting block A515 and the cutting blade 516 to move upward. At this time, the cutting blade 516 contacts the casting formed in the cavity mold 1 and cuts and trims the edge of the casting with the rotation of the bevel gear ring 512. Simultaneously, the reciprocating screw 55, driven in the reverse direction by the motor 51, drives the moving column 58 and the extrusion die 59 to return to their original positions. The movable telescopic rod A53 then moves upward, disengaging the bevel gear A510 from the bevel gear ring 512. The elastic telescopic rod B513, under its own elastic force, drives the roller 514 back into the annular frame 517, and the cutting disc 516 returns to its initial position, completing one cycle of casting forming and finishing. This mold achieves the linkage between extrusion forming and automatic cutting through the forward and reverse rotation of the motor 51, effectively improving the production efficiency and processing accuracy of lightweight aluminum alloy conductor castings. Furthermore, the coordinated design of the elastic telescopic rod and the annular frame 517 ensures the stable storage of the cutting disc 516 when not in operation.

[0032] Example 2, see Figures 1-7In this embodiment, based on Embodiment 1, a grinding assembly 6 is fitted to the outer wall of the elastic telescopic rod B513. The grinding assembly 6 includes a connecting plate B61, which is fixedly sleeved on the outer wall of the elastic telescopic rod B513. An mounting plate 62 is fixedly connected to the other end of the connecting plate B61. An annular slide rail 63 and an annular gear ring 67 are fixedly sleeved on the outer wall of the annular frame 517. A slider 64 is slidably connected to the outer wall of the annular slide rail 63. A movable telescopic rod C65 is rotatably connected to the outer wall of the slider 64. The bottom of the movable telescopic rod C65 passes through the slider 64 and is fixedly connected to a linkage gear 66. The upper end of the movable telescopic rod C65 rotatably passes through the mounting plate 62. A grinding roller 611 is fixedly connected to the Shandong crown of the transmission wheel D69.

[0033] The linkage gear 66 is located outside the ring gear 67, and the linkage gear 66 meshes with the ring gear 67. This meshing relationship ensures that the two can work closely together during the movement, thereby realizing the effective transmission of power and the coordination of mechanical operation.

[0034] A transmission wheel C68 is fixedly sleeved on the outer wall of the movable telescopic rod C65. A transmission wheel D69 is rotatably connected to the upper end of the mounting plate 62. A transmission belt B610 is wound around the outer wall of the transmission wheel C68 and the transmission wheel D69. The entire structure is designed to efficiently transmit the movement of the movable telescopic rod C65 to other components through the transmission belt B610 to achieve the required mechanical function.

[0035] In practical use, when the elastic telescopic rod B513 rotates with the bevel gear ring 512, the connecting plate B61 drives the mounting plate 62 to rotate synchronously. The mounting plate 62 drives the slider 64 to slide along the annular slide rail 63 via the movable telescopic rod C65. At the same time, the linkage gear 66 at the bottom of the movable telescopic rod C65 rotates under the meshing action of the annular gear ring 67. The linkage gear 66 drives the transmission wheel C68 to rotate via the movable telescopic rod C65. The transmission wheel C68 drives the transmission wheel D69 and the grinding roller 611 to rotate via the transmission belt B610. When the cutting blade 516 moves upward to cut the edge of the casting, the elastic telescopic rod B513 extends and drives the movable telescopic rod C65 to move upward synchronously, so that the grinding roller 611 contacts the edge of the casting after cutting. While revolving with the bevel gear ring 512, it achieves rotational grinding, thereby simultaneously smoothing the edge of the casting after cutting, further improving the processing quality of the casting.

[0036] Example 3, see Figures 1-7In this embodiment, based on embodiment one, a dust removal component 7 is assembled on the outer wall of the annular frame 517. The dust removal component 7 includes an L-shaped plate 71, which is fixedly connected to the outer wall of the annular frame 517. A fixing cylinder 72 is fixedly connected to the inner side of the L-shaped plate 71. An airbag 73 is provided inside the fixing cylinder 72. A circular block 74 is slidably connected inside the fixing cylinder 72. A linkage rod 75 is fixedly connected to the outer side of the circular block 74. An air outlet pipe 76 is assembled on the upper and lower air outlets of the airbag 73. An air blowing cover 77 is fixedly connected to the other end of the two air outlet pipes 76. A cam block 78 is fixedly connected to the upper end of the conical ring 512.

[0037] The airbag 73 is equipped with two air outlets and one air inlet, and both the air outlet and the air inlet are equipped with one-way valves. The one-way valve design can ensure that the gas has a clear direction during the flow process, thereby avoiding gas backflow and improving the stability and reliability of the entire airbag 73 system.

[0038] The two air blowing hoods 77 are positioned opposite the upper end of the conical tooth ring 512 and the outer side of the annular tooth ring 67, respectively. This layout design allows the air blowing hoods 77 to effectively blow air onto these two parts, thereby achieving the expected functional effect.

[0039] In practical use, when the bevel gear ring 512 rotates, the cam block 78 at its upper end rotates synchronously. When the protruding part of the cam block 78 contacts the linkage rod 75, it pushes the linkage rod 75 to move into the fixed cylinder 72, thereby driving the circular block 74 to squeeze the air bag 73. This causes the gas in the air bag 73 to be ejected from the air blower 77 through the air outlet pipe 76. One of the air blowers 77 faces the upper end of the bevel gear ring 512 and can blow away the metal chips generated during cutting and grinding from the tooth groove of the bevel gear ring 512, preventing the accumulation of chips from affecting the meshing accuracy of the bevel gear A510 and the bevel gear ring 512. The other air blower 77 faces the outer side of the ring gear ring 67 and can remove the chips at the meshing point of the ring gear ring 67 and the linkage gear 66, preventing the chips from getting stuck and causing the linkage gear 66 to be obstructed from rotating, thus ensuring the stable operation of the grinding assembly 6. After the protruding part of the cam block 78 leaves the linkage rod 75, the air bag 73 returns to its original position under its own elasticity, and draws in air from the outside through the air inlet to prepare for the next blowing. This dust removal component 7 uses the rotational power of the bevel gear ring 512 to achieve automatic intermittent blowing, without the need for an additional power source. It has a compact structure and is energy-saving and environmentally friendly, effectively reducing the wear of metal debris on the mold transmission components and extending the service life of the equipment.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
