Description
Technical Field
[0001] This utility model relates to the field of metal forming technology, and in particular to a die-casting device for aluminum alloy production and processing. Background Technology
[0002] Aluminum alloy die casting, as a highly efficient and precise metal forming technology, plays a crucial role in various fields such as automobile manufacturing, electronics production, and aerospace. This process involves injecting molten aluminum alloy into a mold cavity under high pressure, and after cooling and solidification, obtaining parts of the desired shape. It boasts advantages such as high production efficiency, high finished product precision, and high material utilization.
[0003] However, traditional aluminum alloy die-casting equipment presents a series of problems that urgently need to be addressed. First, the mold changeover process is cumbersome and time-consuming, which not only affects the flexibility of the production line but also increases operating costs. Second, temperature control is not precise enough; temperature fluctuations in the aluminum alloy during die-casting directly affect its fluidity and solidification quality, thus impacting the mechanical properties and surface quality of the final product. Furthermore, low production efficiency is a major drawback of traditional die-casting equipment, primarily due to inaccurate mold positioning and excessively long die-casting cycles.
[0004] More importantly, during the die-casting process of aluminum alloys, the mold is often affected by the die-casting force, causing deviations. Even a small deviation can lead to substandard quality or dimensional errors in the subsequently processed aluminum alloy parts, and in severe cases, it can even damage the mold, further increasing production and maintenance costs.
[0005] Therefore, there is a need to provide a die-casting apparatus for the production and processing of aluminum alloys. Utility Model Content

Detailed Implementation
[0024] The present invention will now be described in detail with reference to the accompanying drawings.
[0025] Example: A die-casting apparatus for aluminum alloy production and processing, such as Figures 1-8As shown, the die-casting device includes a die-casting unit body 1, an injection area 2, a connecting cabinet 3, an upper mold 4, an injection pipe 5, a lower mold 6, a lower pressure component 7, a motor 8, a horizontal plate 9, a gear set 10, a large gear 11, a rack 12, a clamping frame 13, a cylinder 14, a pushing frame 15, and a top plate 16. The die-casting unit body 1 serves as the main structure of the entire die-casting device, supporting and accommodating all other components. The injection area 2 is located on the upper right side of the die-casting unit body 1, used to store and prepare the aluminum alloy material required for die casting. The connecting cabinet 3 is connected to the lower right side of the die-casting unit body 1. The injection pipes 5 are symmetrically connected to the bottom of the injection area 2. A lower pressure component 7 is installed at the center of the bottom of the injection area 2, used to apply pressure during the die-casting process to ensure that the aluminum alloy material can be deposited. The mold cavity is fully filled. An upper mold 4 is installed inside the lower part of the lower pressing component 7. The upper mold 4 is designed to be detachable for easy replacement with different specifications. A lower mold 6 is installed on the top of the connecting cabinet 3. The lower mold 6 works with the upper mold 4 to complete the die-casting process. The upper mold 4 is connected to the other end of two injection pipes 5, which are used to transport aluminum alloy material from the injection area 2 to the upper mold 4. An injection port is provided at the bottom of the upper mold 4 to facilitate the input of aluminum alloy die-casting material between the upper mold 4 and the lower mold 6. A motor 8 is vertically installed downwards and slightly to the left of the top center position inside the connecting cabinet 3. Two horizontal plates 9 are horizontally connected at the upper center position inside the connecting cabinet 3. The two horizontal plates 9 are symmetrically designed and connected between the output shaft of the motor 8 and the center position of the upper horizontal plate 9. There is a gear set 10, which consists of two gears. The two gears are respectively connected to the output shaft of the motor 8 and the center of the upper horizontal plate 9. A large gear 11 is rotatably connected to the center of the lower horizontal plate 9. The large gear 11 is connected to the bottom of the lower gear in the gear set 10. Clamping frames 13 are slidably connected to the front and rear sides of the upper part of the connecting cabinet 3. The inner side of the clamping frame 13 is provided with an anti-slip pad, which can increase the contact friction between the clamping frame 13 and the lower mold 6 and play an anti-slip role. The inner side of the upper end of the clamping frame 13 contacts the two sides of the lower mold 6, which can clamp the lower mold 6 and ensure that the lower mold 6 is not easy to move. The lower end of the clamping frame 13 is connected to a rack 12, which meshes with the large gear 11. The gear set 10 is driven by the motor 8, thereby... The large gear 11 is driven to rotate, which in turn drives the rack 12 to move, causing the clamping frame 13 to move back and forth. A cylinder 14 is vertically installed at the bottom center of the connecting cabinet 3. The piston rod of the cylinder 14 is connected to a push frame 15. The middle part of the push frame 15 is hollowed out, and the push frame 15 is located outside the gear set 10, the large gear 11 and the two horizontal plates 9. When the push frame 15 rises, it will not obstruct the use of the gear set 10, the large gear 11 and the two horizontal plates 9. A top plate 16 is connected to the top of the push frame 15. The top plate 16 is located in the middle of the lower mold 6. The top plate 16 can penetrate the top of the connecting cabinet 3. The cylinder 14 drives the push frame 15 to move upward, thereby driving the top plate 16 to move upward, and thus ejecting the die-cast product for easy material removal.
[0026] When the die-casting device is required, the aluminum alloy material to be die-cast is first added to the injection zone 2 on the upper part of the die-casting device body 1. The upper mold 4 is connected to the injection zone 2 through the injection pipe 5 to ensure that the aluminum alloy material can smoothly enter the mold cavity.
[0027] Next, start motor 8. Motor 8 drives gear set 10 to rotate, causing large gear 11 to rotate. The rotation of large gear 11 drives rack 12, which meshes with it, to move, thereby causing clamping frame 13 to move back and forth. The upper end of clamping frame 13 contacts both sides of lower mold 6 and applies sufficient clamping force to ensure that lower mold 6 does not move during die casting.
[0028] Then, open the outlet of injection zone 2, and the aluminum alloy material flows into the injection port of upper mold 4 through injection pipe 5. As the lower pressure component 7 is activated, it drives upper mold 4 to move downward, so that upper mold 4 and lower mold 6 fit tightly together. At this time, the aluminum alloy material in upper mold 4 can fill the mold cavity. After filling, close the injection port in time.
[0029] Next, apply sufficient pressure to the aluminum alloy material using the pressure lowering component 7 to ensure that the material fully fills all corners of the mold cavity. Maintain a certain pressure and time to ensure the quality and density of the die-cast product.
[0030] After die casting is completed, the lower die 7 will move the upper die 4 upwards to reset. Then, the material removal step begins. By activating cylinder 14, the piston rod of cylinder 14 drives the pusher frame 15 to move upwards. The top plate 16 connected to the top of the pusher frame 15 rises accordingly, ejecting the die-cast product from the lower die 6. When the top plate 16 rises to a certain height, the operator can easily remove the die-cast product.
[0031] After removing the die-cast product, the cylinder 14 is closed, causing the pusher frame 15 and the top plate 16 to descend to their initial positions, ready for the next round of die-casting operations.
[0032] If it is necessary to change the lower mold 6 to produce products of different specifications, the motor 8 can be reversed to loosen the clamping frame 13 from clamping the lower mold 6. In this way, the lower mold 6 can be easily changed. Through the clamping action of the clamping frame 13, the position of the lower mold 6 can be precisely adjusted to ensure that it is aligned with the position of the upper mold 4, thereby guaranteeing the precision and quality of the die-cast products.
[0033] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
