Description

Technical Field

[0001] This invention relates to the field of metal casting technology, specifically to an aluminum die casting machine. Background Technology

[0002] Aluminum die casting machines are devices that inject molten aluminum alloy into a metal mold under high pressure. They are widely used in the automotive, aerospace, electronics, and home appliance industries, especially in the automotive industry for manufacturing key components such as engine parts and body parts. Aluminum die casting technology, with its high precision, ability to produce complex shapes, good mechanical properties, lightweight characteristics, and corrosion resistance, has become an important means of lightweight design. Its working principle involves heating the aluminum alloy to a molten state and injecting it into a mold under high pressure. After cooling, the casting is demolded to form a part. Aluminum die casting machines offer high production efficiency, good material recyclability, and low energy consumption, and also have advantages in environmental protection. With the continuous development of automation and intelligent technologies, aluminum die casting technology is progressing towards greater refinement and environmental friendliness, and will play an even more important role in high precision, high efficiency, and environmental protection in the future.

[0003] A search revealed an existing patent application (publication number: CN110802214A) disclosing a low-pressure aluminum alloy casting machine, comprising a machine body. An air inlet pipe is installed through the front surface of the machine body. A control switch is located on the front surface of the machine body near the air inlet pipe. A feed pipe is installed through the front surface of the machine body near the lower part of the air inlet pipe. A groove is formed on the side wall of the machine body, and a support rod is rotatably connected to the corresponding groove. A movable platform is hinged to the side wall of the machine body near the groove. In this invention, the vacuum suction cup greatly facilitates the removal of formed workpieces by the operator, improving work efficiency. The movable platform greatly facilitates the placement of workpieces by the operator, avoiding cluttered workpiece placement and improving space utilization. The toolbox ensures the standardized organization of maintenance tools, provides good protection, and prevents loss due to careless use. This casting machine is simple to operate and highly practical.

[0004] However, in actual use, the above-mentioned solution allows only one workpiece to be cast at a time. After casting, the workpiece must be allowed to cool and solidify before it can be removed for the next casting cycle. This operation leads to low production efficiency of the aluminum die casting machine because each casting cycle is long, resulting in excessive machine idle time and failure to fully utilize the equipment's production capacity. This inefficient production method not only increases the unit casting cost but also reduces production flexibility. Especially when rapidly adjusting production plans or diversifying production, machine turnaround and adjustment times become limiting factors. Furthermore, the prolonged cooling process and frequent use can lead to wear and tear on equipment components, increasing maintenance frequency and costs. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an aluminum die casting machine. After each die casting cycle, the casting mold assembly can be directly replaced, along with the die-cast workpiece, significantly improving the machine's production efficiency. This reduces downtime during mold assembly replacement, avoids machine idle time, and ensures continuous and efficient production. The machine can then quickly proceed to the next casting cycle, increasing production capacity and output per unit time, while also enhancing production flexibility by allowing for rapid adjustments to the type and size of workpieces produced, thus solving the aforementioned technical problems.

[0041] The casting mold assembly is set on the extrusion end of the extrusion assembly. The extrusion end of the extrusion assembly extrudes the casting mold assembly, making the casting mold assembly fit more tightly.

[0042] The cooling component is located on the outside of the support plate 11, and the support plate 11 supports the cooling component.

[0043] The fixing frame 4 is fixed to the top of the support plate 11 and the top of the extrusion assembly, and the support plate 11 supports and fixes the fixing frame 4.

[0044] The mold lateral movement assembly is located on the top of the fixed frame 4, and the fixed frame 4 supports the mold lateral movement assembly.

[0045] The mold handling and lifting assembly is located at the moving end of the mold traversing assembly, and drives the mold handling and lifting assembly to move synchronously through the mold traversing assembly;

[0046] The mold fixing component is located at the top of the conveying end of the mold conveying and lifting component, and the mold fixing component is moved synchronously by the mold conveying and lifting component.

[0047] The extrusion assembly includes a stress plate 12 fixed to the top middle section of a base 1, a sliding rod 15 evenly distributed on the inner walls of two side support plates 11, a first hydraulic rod 13 fixed to the outer wall of the support plate 11 at the end away from the cooling assembly, and the sliding rod 15 passing through the stress plate 12 and fixedly connected to the inner walls of the two side support plates 11. The support plates 11 support and fix the stress plate 12, while the sliding rod 15 supports and fixes the support plates 11. 1. The first hydraulic rod 13 is connected and fixed to the stress plate 12. The output end of the first hydraulic rod 13 passes through the stress plate 12 and is fixedly connected to the sliding plate 14. The first hydraulic rod 13 drives the sliding plate 14 to move laterally through the stress plate 12 with the support plate 11 as the stress point. The sliding plate 14 is slidably connected to the slide rod 15. The slide rod 15 limits the sliding plate 14, so that the sliding plate 14 slides outside the slide rod 15. The support plate 11 and the top wall of the stress plate 12 at the end away from the first hydraulic rod 13 are fixedly connected to the fixed frame 4. The support plate 11 and the stress plate 12 simultaneously support and fix the fixed frame 4.

[0048] The casting mold assembly includes a first mold 16 slidably connected to the outer wall of a support plate 11 near the first hydraulic rod 13, and a second mold 17 slidably connected to the outer wall of a sliding plate 14 away from the first hydraulic rod 13. The first mold 16 and the second mold 17 are engaged. The first mold 16 is slidably connected to the support plate 11 via engaging blocks and slots, while the second mold 17 is slidably connected to the sliding plate 14 via the same engaging blocks and slots. The slots on the support plate 11 and the sliding plate 14 limit the engaging blocks on the outer sides of the first mold 16 and the second mold 17, ensuring that the first mold 16 and the second mold 17 are positioned within the support plate 11 and the sliding plate 14. The sliding plate 14 slides on its outer wall. Simultaneously, after the positions of the first mold 16 and the second mold 17 are determined on the support plate 11 and the sliding plate 14, their positions are fixed by the mold lateral movement assembly. The first mold 16 and the second mold 17 are made of H13 mold steel. H13 steel has excellent high-temperature resistance, capable of withstanding the high temperatures generated during aluminum alloy casting while maintaining its hardness and strength. It can operate at high temperatures and is particularly suitable for hot-working molds, such as die-casting molds and forging molds. H13 mold steel also has good thermal stability and thermal shock resistance, making it suitable for rapid cooling along with the castings. During aluminum alloy die casting, the mold typically undergoes drastic temperature changes from high temperature to cooling water. H13 steel can withstand these rapid temperature changes without cracking or other structural damage.

The chiller 3 is connected to the cooling box 21 through the water inlet pipe 31 and the water outlet pipe 32. The chiller 3 delivers cold water into the cooling box 21 through the water inlet pipe 31 and extracts the cooling water from the cooling box 21 through the water outlet pipe 32.

[0050] The mold traversing assembly includes a first motor 41 fixed to one end of the outer side of the fixed frame 4, which supports and fixes the first motor 41. A driven wheel 44 is rotatably connected to one end of the inner side of the fixed frame 4, which supports and limits the driven wheel 44. A driving wheel 42 is fixedly connected to the output end of the first motor 41, which fixes the driving wheel 42 and drives the driving wheel 42 to rotate. A belt 43 is rotatably connected to the outer side of the driving wheel 42, and the other end of the belt 43 is rotatably connected to the driven wheel 44. The driving wheel 42 drives the belt 43, and the driven wheel 44 limits the belt 43.

[0051] The mold handling and lifting assembly includes first slide rails 45 fixed on both sides of the bottom of a fixed frame 4. The fixed frame 4 supports and fixes the first slide rails 45 on both sides. First sliders 46 are slidably connected to the outer side of the first slide rails 45, limiting the movement of the first sliders 46. A lifting frame 5 is fixedly connected to the top of the first sliders 46, supporting and fixing the lifting frame 5. This allows the lifting frame 5 to slide on the bottom of the fixed frame 4 using the first slide rails 45 and the first sliders 46. The top of the lifting frame 5 is fixedly connected to the middle section of a belt 43, fixing the lifting frame 5 and moving it through the rotation of the belt 43. A second motor 51 is fixedly connected to the top of the lifting frame 5, supporting and fixing it. The output end of the second motor 51 is fixedly connected to... A lead screw 52 is fixed by a lifting frame 5, which also drives the lead screw 52 to rotate. Second slide rails 55 are fixedly connected to both sides of the outer wall of the lifting frame 5, supporting and fixing the second slide rails 55. A second slider 56 is slidably connected to the outer side of the second slide rails 55, limiting the movement of the second slider 56 outside the second slide rails 55. A support frame 54 is fixedly connected to the outer wall of the second slider 56, supporting and fixing the support frame 54. A threaded plate 53 is fixedly connected to the outer side of the support frame 54, supporting and fixing the threaded plate 53. The threaded plate 53 is threadedly connected to the lead screw 52. A second motor 51 drives the lead screw 52 to rotate, and simultaneously, the lead screw 52 drives the threaded plate 53 to rise and fall.

[0052] The mold fixing assembly includes a second hydraulic rod 6 fixed to the top of the support frame 54. The support frame 54 supports and fixes the second hydraulic rod 6. The output end of the second hydraulic rod 6 is provided with a locking rod 61. The second hydraulic rod 6 drives the locking rod 61 to rise and fall. The locking rod 61 is engaged with the pouring port opened on the top of the casting mold assembly. The locking rod 61 engages with the pouring port, thus completing the connection between the support frame 54 and the casting mold assembly after the support frame 54 supports the casting mold assembly and the locking rod 61 engages with the pouring port.

[0053] The outer wall of the support plate 11 near the first hydraulic rod 13 is detachably connected to a uniformly distributed guard plate 18. The guard plate 18 is supported and fixed by the support plate 11, and the guard plate 18 protects the outside of the equipment.

[0054] The bottom opening height of the support bracket 54 is the same as the height of the casting mold assembly. By setting the opening height of the support bracket 54 to be the same as the height of the casting mold assembly, the casting mold assembly can be fixed more stably.

[0055] The support frame 54 is slidably connected to the inner wall of the cooling box 21. At the same time, the opening height of the support frame 54 is the same as the depth of the cooling box 21. By setting the opening height of the support frame 54 to be the same as the depth of the cooling box 21, the casting mold assembly can be completely placed inside the cooling box 21 to cool the casting mold assembly.

[0056] In use, the first mold 16 and the second mold 17 are first installed on the outer wall of the support plate 11 and the sliding plate 14 respectively by the locking block and the locking groove. Then, the support bracket 54 on the mold transverse moving assembly supports the middle section of the first mold 16 and the second mold 17, thereby fixing the position of the first mold 16 and the second mold 17. Then, molten metal is injected into the first mold 16 and the second mold 17 through the pouring port.

[0057] After the molten metal cools and solidifies in the first mold 16 and the second mold 17, the second motor 51 drives the threaded plate 53 and the support frame 54 to move to the bottom via the lead screw 52, ​​thereby aligning the support frame 54 with the casting mold assembly. Then, the first motor 41 drives the belt 43 to rotate via the drive wheel 42. During this process, the belt 43 drives the lifting frame 5 to move to one side of the casting mold assembly, and the support frame 54 is sleeved on the outside of the casting mold assembly. Then, the second hydraulic rod 6 drives the locking rod 61 to move downward and inserts the locking rod 61 into the pouring port, thereby connecting the support frame 54 and the locking rod 61. Then, the first motor 41 reverses, driving the lifting frame 5 to move outward, thereby pulling the casting mold assembly out from the inside of the support plate 11 and the sliding plate 14.

[0058] Then, the second motor 51 drives the lead screw 52 to rotate, and at the same time, the lead screw 52 drives the threaded plate 53 and the support frame 54 to move to the bottom and fall into the cooling box 21, so that the cooling water inside the cooling box 21 cools down the casting mold assembly and the workpiece.

[0059] During the process, chilled water is supplied to the cooling tank 21 through the inlet pipe 31 via the chiller 3, and the cooling water in the cooling tank 21 is extracted through the outlet pipe 32. The chiller 3 then cools down the heated cooling water.
