Description

Technical Field

[0001] The present invention relates to the technical field of metal die-casting, and in particular to an aluminum alloy ingot die-casting device and a use method thereof. Background Art

[0002] Aluminum alloy ingot die casting is a precision casting method that injects molten metal into a mold cavity under high pressure and solidifies it to obtain the desired shape and size. Aluminum alloy ingot die casting uses high pressure to quickly fill liquid or semi-liquid aluminum alloy into the mold cavity and quickly solidifies it under pressure. This process not only ensures the accuracy of the casting, but also improves production efficiency; aluminum alloy ingot die casting has the characteristics of high dimensional accuracy, high surface finish and good mechanical properties. Through high pressure and high-speed filling, aluminum alloy ingots can be formed into complex and thin-walled structural parts to meet the modern industry's demand for lightweight and high-strength parts; aluminum alloy ingot die casting is widely used in many fields such as automobile manufacturing, aerospace, electronic equipment, and architectural decoration. In the automotive industry, aluminum alloy ingot die-casting is used in key parts such as engine components and body structures, which helps to reduce vehicle weight and improve fuel efficiency; compared with traditional casting methods, aluminum alloy ingot die-casting can produce more complex and sophisticated parts, while reducing the need for subsequent processing, reducing costs and time consumption; with the advancement of science and technology, aluminum alloy ingot die-casting technology will continue to be optimized, especially in the fields of new energy vehicles and intelligent manufacturing, the application will be more extensive, the development of new materials and the improvement of environmental protection requirements will also promote the further development of aluminum alloy ingot die-casting technology. In general, aluminum alloy ingot die-casting, as an efficient and precise metal forming process, plays an increasingly important role in modern manufacturing.

[0003] The patent with patent publication number CN114101632A discloses an aluminum alloy ingot die-casting device with a buffer positioning function, which solves the problem of collision between the pressure plate and the bottom plate, which easily causes damage to the pressure plate and the bottom plate. The device comprises a bottom plate, and support legs are installed at the four corners of the bottom end of the bottom plate, and positioning rods are installed at the four corners of the top end of the bottom plate. A top plate is installed at the top of the positioning rod, and a control is installed on the front of the top plate; after it moves downward through the set sleeve plate, the buffer groove is located near the top of the air outlet groove. When the insertion rod moves downward, it pushes the gas in the bottom groove of the positioning rod to spray upward from the air outlet groove. Since the downward pressing speed of the pressure plate is relatively fast, the gas spraying speed at the air outlet groove is relatively fast, and at this time the gas sprays upward to the bottom end of the buffer plate, thereby pushing the buffer plate to move upward, thereby further producing a buffering effect on the pressure plate, thereby improving the protection of the equipment.

[0004] The prior art has the following defects:

[0005] In the prior art, the forming process of aluminum alloy ingots usually takes place in a relatively compact die-casting tank. After the aluminum alloy ingot is formed, it is located in the die-casting tank, and the space in the die-casting tank is small, and there is a lack of a structure to eject the formed aluminum alloy ingot. As a result, when the operator needs to take out the formed aluminum alloy ingot, the operating space is limited, and the aluminum alloy ingot cannot be taken out conveniently and quickly. This reduces the production and processing efficiency of the aluminum alloy ingots, and increases the labor intensity of the operator in taking out the aluminum alloy ingots, making it inconvenient for the operator to take out the aluminum alloy ingots. Therefore, it needs to be further optimized. Summary of the invention

[0050] Embodiment 2:

[0051] Reference Figure 1-9, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the upper mold shift unit 4 includes a shift component 41, which is arranged on the molding ejection component 31, and a driving component 42 is arranged on the shift component 41; the shift component 41 includes a lifting round block 411, and four vertical guide rods 412 are symmetrically and longitudinally penetrated and slidably connected on the lifting round block 411, the top of the vertical guide rod 412 is fixedly connected to the inner top of the fixed cylinder 321, and the bottom of the vertical guide rod 412 is fixedly connected to the top of the table 1, and a lifting frame 413 is rotatably sleeved on the lifting round block 411, and one end of the lifting frame 413 is fixedly connected to the top of the upper mold 312, and a lower vertical guide groove 414, a spiral guide groove 415 and an upper vertical guide groove 416 are opened on the side wall of the fixed cylinder 321 from bottom to top, and the lifting frame 413 moves through the lower vertical guide groove 414.

[0052] Specifically, when the lifting block 411 moves upward, it moves along the vertical guide rod 412. At the same time, the lifting block 411 drives the lifting frame 413 to move upward, and drives the ejection frame 423 to move upward synchronously. The ejection frame 423 moves longitudinally in the lower vertical guide groove 414 and the upper vertical guide groove 416. When the ejection frame 423 enters the spiral guide groove 415, it moves along the spiral guide groove 415 to generate rotation.

[0053] Reference Figure 1-9 The driving component 42 includes a driving motor 421, which is fixedly connected to the bottom of the table 1. A vertical threaded rod 422 is rotatably connected to the table 1. The vertical threaded rod 422 is longitudinally threadedly connected to the lifting block 411. An ejection frame 423 is fixedly connected to the lifting block 411. A push block 424 is fixedly connected to the lower part of the ejection frame 423. The push block 424 is arranged directly below the fixed block 319.

[0054] Specifically, the rotating end of the driving motor 421 drives the vertical threaded rod 422 to rotate, thereby driving the lifting block 411 to move up and down along the vertical guide rod 412 through the vertical threaded rod 422, so that the lifting block 411 drives the ejection frame 423 to rise and fall synchronously, and the ejection frame 423 drives the push block 424 to rise and fall synchronously; the rest of the structure is the same as that of Example 1.

[0055] Embodiment 3:

[0056] Reference Figure 1-10, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the ejection unit 5 includes an ejection frame 51, the ejection frame 51 is fixedly connected to the top of the table 1, the ejection electric cylinder 52 is fixedly connected to the top of the ejection frame 51, the telescopic end of the ejection electric cylinder 52 is fixedly connected to a U-shaped ejection plate 53, the top of the table 1 is fixedly connected to a pouring channel 54, the U-shaped ejection plate 53 is arranged on one side of the lower mold 311, and the pouring channel 54 is arranged on the other side of the lower mold 311, and the sealing electric cylinder 333, the driving motor 421 and the ejection electric cylinder 52 are all electrically connected to an external control switch controller through a guide.

[0057] Specifically, the ejection frame 51 is used to fix and support the ejection electric cylinder 52, and the telescopic end of the ejection electric cylinder 52 extends to drive the U-shaped ejection plate 53 to move, so that the U-shaped ejection plate 53 pushes the aluminum alloy ingot into the pouring channel 54, and then the aluminum alloy ingot enters the pouring channel 54 and slides down under the action of its own gravity; the rest of the structure is the same as that of Example 2.

[0058] Embodiment 4:

[0059] Reference Figure 1-10 , which is the fourth embodiment of the present invention, provides: a method for using an aluminum alloy ingot die-casting device, and the method steps are as follows:

[0060] First, the high-temperature molten aluminum alloy liquid is transported to the feed tank 323 through an external conveying device. The aluminum alloy liquid in the feed tank 323 then enters the vertical pipe sleeve 326 through the connecting pipe 324, and finally enters the feed channel 325. The aluminum alloy liquid flows into the die-casting tank 313 through the feed channel 325.

[0061] When the aluminum alloy liquid in the die-casting tank 313 is filled, the sealing electric cylinder 333 is started, and the telescopic end of the sealing electric cylinder 333 extends to drive the sealing push rod 334 to move the sealing plug 335 downward until the sealing plug 335 blocks the lower part of the feed channel 325. The sealing plug 335 is pressed downward, so that the aluminum alloy liquid in the lower part of the feed channel 325 is further squeezed into the die-casting tank 313, thereby making the aluminum alloy liquid in the die-casting tank 313 more compact and reducing the presence of bubbles.

[0062] The cooling liquid is circulated into the cooling coil 317 through an external circulating coolant delivery device, so that the heat generated by the aluminum alloy liquid in the die-casting tank 313 is transferred to the lower mold 311, and the lower mold 311 transfers the heat to the cooling coil 317. The cooling coil 317 exchanges heat with the coolant circulating through the interior, so that the heat of the aluminum alloy liquid is removed by the circulating coolant, and the aluminum alloy liquid is cooled and formed, and finally an aluminum alloy ingot is formed.

[0063] After the aluminum alloy ingot is formed, the driving motor 421 is started, and the rotating end of the driving motor 421 rotates to drive the vertical threaded rod 422 to rotate synchronously. Under the thread cooperation between the vertical threaded rod 422 and the lifting round block 411, the vertical threaded rod 422 rotates to drive the lifting round block 411 to slide upward along the vertical guide rod 412. The lifting round block 411 moves upward while driving the lifting frame 413 to move upward, so that the lifting frame 413 first moves upward along the lower vertical guide groove 414, thereby driving the upper mold 312 to move to the upper moving distance of the lower mold 311 through the lifting frame 413, and then the lifting frame 413 enters the spiral guide groove 414 from the lower vertical guide groove When the lifting frame 413 enters the spiral guide groove 415 and moves upward along the spiral guide groove 415, the lifting frame 413 rotates on the lifting block 411, and the upper mold 312 is driven to rotate synchronously through the rotation of the lifting frame 413. During the process of the upper mold 312 driving the vertical pipe sleeve 326 to move upward, the vertical pipe sleeve 326 slides upward along the connecting pipe 324, and when the lifting frame 413 rotates, the fixed bracket 322 and the feed tank 323 rotate synchronously until the upper mold 312 is rotated 90 degrees and then staggered with the lower mold 311, so that the upper mold 312 and the lower mold 311 are staggered to facilitate the removal of the aluminum alloy ingot later.

[0064] When the lifting block 411 moves upward, it drives the ejector frame 423 to move upward synchronously. When the lifting frame 413 moves to the top of the spiral guide groove 415, the ejector frame 423 drives the push block 424 to just contact the fixed block 319, and then the lifting block 411 continues to move upward, and the lifting frame 413 moves upward along the upper vertical guide groove 416. The push block 424 pushes the fixed block 319 to move the vertical slide bar 318 and the ejector push block 315 upward, and the ejector push block 315 pushes the aluminum alloy ingot that has been cooled and formed in the die-casting groove 313 to the top of the lower mold 311.

[0065] The ejection electric cylinder 52 is then started, and the telescopic end of the ejection electric cylinder 52 extends to drive the U-shaped ejection plate 53 to move, so that the U-shaped ejection plate 53 pushes the aluminum alloy ingot into the pouring channel 54. After the aluminum alloy ingot enters the pouring channel 54, it slides down under the action of its own gravity, thereby completing the die-casting of an aluminum alloy ingot.

[0066] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
