Description

Technical Field

[0001] The utility model relates to the technical field of casting, and more particularly to a mold for aluminum alloy casting. Background Art

[0002] In the existing technology, firstly, some devices have precise hydraulic control, and the mold closure may not be tight enough, affecting the quality of the casting. The force and precision of each mold closure may be inconsistent, resulting in fluctuations in the quality of the casting. Secondly, some devices may not be able to evenly fill the mold with aluminum alloy melt, resulting in defects such as air holes and shrinkage holes. Due to the lack of vibration, the fluidity of the melt in the mold is reduced, and it may not be able to completely fill complex shapes. Segregation, looseness and other problems may occur during the solidification process of the melt, affecting the internal structure of the casting, slowing down the injection process, increasing the production cycle, and making it difficult to adapt to aluminum alloy materials with different viscosities and flow characteristics. Additional manual intervention is required to ensure that the melt is evenly distributed. Finally, some devices adjust the vibration parameters according to different materials and casting requirements, making it difficult to adapt to the needs of castings of different sizes, shapes and complexities. The vibration parameters cannot be optimized for specific castings, which may affect the quality of the casting. Utility Model Content

[0030] In this embodiment, the hydraulic cylinder 2 is activated, pushing the first mold 4 and the second mold 5 toward each other. The guide rod 7 and the guide sleeve 6 ensure the smooth movement of the molds. The two molds are closed to form a casting cavity, ready for the injection of materials. The aluminum alloy material is added to the injection pipe 8 through the adding bucket 20. The vibration motor 10 is started, driving the entire injection pipe 8 to vibrate. The vibration is transmitted to the support column 11 and the mold through the vibration spring 12. The vibration promotes the uniform flow of the aluminum alloy material and fills the mold.

[0031] The amplitude adjustment mechanism includes a directional sleeve 14, a rotating sleeve 15, a threaded rod 16 and an adjusting piece 17. The rotating sleeve 15 is limitedly rotated and set on the top end surface of the top frame 13. The directional sleeve 14 is fixedly set at the bottom of the top frame 13. The threaded rod 16 is set in the directional sleeve 14 for directional movement. The rotating sleeve 15 rotates, driving the threaded rod 16 to move in a directional manner on the top frame 13 and the directional sleeve 14. Multiple groups of adjusting pieces 17 are installed on the vibration spring 12, and the threaded rod 16 passes through the adjusting pieces 17 in sequence. The number of different adjusting pieces 17 passed through changes the properties of the vibration spring 12, and then changes the preload force of the vibration spring 12.

[0032] In this embodiment, the rotating sleeve 15 is rotated to drive the threaded rod 16 to move in the directional sleeve 14. The threaded rod 16 passes through different numbers of adjustment plates 17. The change in the number of adjustment plates 17 changes the preload force of the vibration spring 12. The change in the preload force adjusts the amplitude and frequency of the vibration.

[0033] See also Figure 1-5 , as a supplementary implementation method of an aluminum alloy casting mold for a push molding mechanism, a vibration injection mechanism and an amplitude adjustment mechanism: a diagonal support plate 18 is installed on the top of the lateral plate 3, and a mounting plate 19 is installed on the bottom of the support column 11, and the mounting plate 19 is cooperatively installed on the top end surface of the diagonal support plate 18, an adding bucket 20 is installed on the top of one end of the injection pipe 8, and external materials can enter the injection pipe 8 through the adding bucket 20, an injection hole 21 is opened on the top of the first mold 4 and the second mold 5, a connecting bucket 22 is installed on the bottom of one end of the injection pipe 8, and the output end of the connecting bucket 22 is opposite to the injection hole 21, a cooling pipe 23 is installed on the bottom plate 1, and the other end of the cooling pipe 23 extends through the interior of the bottom plate 1, a mounting frame 24 is installed on the top of the injection pipe 8, and the vibration motor 10 is cooperatively arranged on the mounting frame 24, and the adding bucket 20, the connecting bucket 22 and the interior of the injection pipe 8 constitute an injection cavity 9.

[0034] More specifically, check the working status of all mechanisms, adjust the amplitude adjustment mechanism as needed, set appropriate vibration parameters, start the hydraulic cylinder 2, push the first mold 4 and the second mold 5 to close, the guide rod 7 and the guide sleeve 6 ensure that the molds are precisely aligned, add the molten aluminum alloy material to the injection pipe 8 through the adding bucket 20, start the vibration motor 10, start the vibration process, and the vibration is transmitted to the entire injection system through the vibration spring 12. Under the action of vibration, the molten aluminum alloy enters the injection hole 21 of the mold through the connecting bucket 22. The vibration promotes the uniform distribution of the material and fills the mold cavity. Start the cooling pipe 23 in the bottom plate 1 and start the cooling process. The aluminum alloy gradually cools and solidifies in the mold. After cooling is completed, the hydraulic cylinder 2 moves in the opposite direction to separate the first mold 4 and the second mold 5 and take out the formed aluminum alloy casting.

[0035] In summary, when the overall equipment is in use or running: when it is necessary to push the molding mechanism to operate, the hydraulic cylinder 2 is started to push the first mold 4 and the second mold 5 to move toward each other, the guide rod 7 and the guide sleeve 6 ensure the smooth movement of the mold, and the two molds are closed to form a casting cavity, ready for the injection of material.

[0036] When the vibration injection mechanism needs to be operated, the aluminum alloy material is added to the injection pipe 8 through the adding bucket 20, and the vibration motor 10 is started to drive the entire injection pipe 8 to vibrate. The vibration is transmitted to the support column 11 and the mold through the vibration spring 12. The vibration promotes the uniform flow of the aluminum alloy material and filling of the mold.

[0037] When the amplitude adjustment mechanism needs to be operated, the rotating sleeve 15 is rotated to drive the threaded rod 16 to move in the directional sleeve 14. The threaded rod 16 passes through different numbers of adjustment plates 17. The change in the number of adjustment plates 17 changes the preload force of the vibration spring 12. The change in the preload force adjusts the amplitude and frequency of the vibration.

[0038] Check the working status of all mechanisms, adjust the amplitude adjustment mechanism as needed, set appropriate vibration parameters, start the hydraulic cylinder 2, push the first mold 4 and the second mold 5 to close, the guide rod 7 and the guide sleeve 6 ensure that the mold is precisely aligned, add the molten aluminum alloy material to the injection pipe 8 through the adding bucket 20, start the vibration motor 10, start the vibration process, and the vibration is transmitted to the entire injection system through the vibration spring 12. Under the action of vibration, the molten aluminum alloy enters the injection hole 21 of the mold through the connecting bucket 22. The vibration promotes the uniform distribution of the material and fills the mold cavity. Start the cooling pipe 23 in the bottom plate 1 and start the cooling process. The aluminum alloy gradually cools and solidifies in the mold. After cooling is completed, the hydraulic cylinder 2 moves in the opposite direction, separates the first mold 4 and the second mold 5, and takes out the formed aluminum alloy casting.

[0039] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded.
