Description

Technical Field

[0001] The present invention relates to the technical field of lightweight aluminum alloy die-casting, and in particular to a die-casting device and a die-casting method for a high-strength and lightweight aluminum alloy structural part. Background Art

[0002] In the current industrial production environment, the existing die-casting devices for die-casting high-strength and lightweight aluminum alloy structural parts are key equipment for manufacturing high-precision and high-quality metal parts, and play a vital role. However, the existing die-casting devices generally face a series of challenges in design and operation, especially in the integration and adaptation of control systems and power sources.

[0003] Most existing die-casting devices for high-strength and lightweight aluminum alloy structural parts use independent control systems and power source configurations. Although this design ensures the independence and flexibility of each device to a certain extent, it also increases operational complexity and maintenance costs. Operators need to be familiar with and master the operating interfaces and control logic of multiple different devices, which undoubtedly increases operational difficulty and labor costs. In addition, independent control systems may also lead to information islands, making data sharing and collaborative operations in the production process difficult.

[0004] In terms of power sources, the power sources of existing die-casting devices often do not have a high degree of versatility and adaptability. Once a power source of a device fails, it is often difficult to quickly find a suitable replacement part due to the differences and non-standardization of power sources between different devices, which prolongs the maintenance time and reduces production efficiency. This non-standardization of power sources may also lead to an increase in spare parts inventory and an increase in costs. Summary of the invention

[0016] A die-casting method for a high-strength and tough lightweight aluminum alloy structural part, applied to the die-casting device for a high-strength and tough lightweight aluminum alloy structural part described above, comprises the following steps: S1: Pretreatment stage: The motor is powered on and runs, and the motor drives the horizontal reciprocating conveying mechanism to start moving, and the mechanism then drives the die-casting frame to move away from the motor. During the movement of the die-casting frame, the upper mold and the lower mold will pass through the heating frame, the release agent spraying frame and the air drying frame in sequence.

Then, the synchronous transmission mechanism operates to close the upper die and the lower die to form a die cavity of the die-casting part. Then, the synchronous transmission mechanism opens the second toothed knob switch between the metal can and the air pressure device, and the liquid inside the metal can is automatically injected into the die cavity by pressurizing. After the injection is completed, the synchronous transmission mechanism continues to operate, driving the upper die and the lower die to rotate synchronously, removing bubbles by centrifugal force, and improving the quality of the casting. After cooling, the synchronous transmission mechanism resets, first stops the mold rotation, then stops the pressurization operation, and then performs the mold separation operation, and finally separates from the annular press frame. After the annular press frame is separated from the synchronous transmission mechanism, the ejector pin resets under the elastic force of the compression spring and ejects the material in the lower die cavity. After the material is ejected, the material can be removed manually or by an intelligent robotic arm. S3: Reset stage: After the material is removed, the motor drives the horizontal reciprocating conveying mechanism to operate again, driving the die-casting frame to reset so as to facilitate the next pre-processing operation.

[0017] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention has a reasonable structure. It uses one power source to drive the entire system, effectively reducing production costs and reducing operating difficulty. This design not only simplifies the complexity of the system, but also makes subsequent maintenance and control work easier. Since the system structure is clear and the components are modular, the control and maintenance work can be carried out more quickly and efficiently. This design greatly improves the reliability and service life of the equipment. Among them, the use of an electric drive mode makes the power source of the present invention highly popular and easy to replace. Once a fault occurs, an alternative motor can be quickly found for replacement, thereby greatly improving the maintenance efficiency and the availability of the equipment; 2. The present invention ingeniously arranges a horizontal reciprocating conveying mechanism and a synchronous transmission mechanism, and drives them through the same motor, wherein the horizontal reciprocating conveying mechanism is mainly responsible for the movement and pretreatment operation of the mold. Driven by the motor, the horizontal reciprocating conveying mechanism can move the mold smoothly and quickly to ensure that the mold is accurately positioned before die-casting. At the same time, during the movement, the mechanism can also drive the mold to preheat, apply a release agent and air-dry, so as to prepare for subsequent die-casting operations. The synchronous transmission mechanism realizes the die-casting operation through the cooperation of various components. Driven by the motor, the synchronous transmission mechanism can accurately control the needle withdrawal, mold closing, material injection, pressure holding, mold separation and ejection of the die-casting mold. This precise control not only improves the quality of the die-casting, but also reduces the difficulty of operation and the failure rate. The two mechanisms are driven by the same motor, so efficient transmission and utilization of power can be achieved. At the same time, the two mechanisms have clear division of labor and do not interfere with each other, so that the overall work efficiency is significantly improved. The same motor is used to drive the two mechanisms, which reduces the manufacturing cost and maintenance cost of the equipment. In addition, due to the popularity and availability of motors, the maintenance and replacement of the equipment also become more convenient and economical. Since the two mechanisms are driven by the same motor, the coordinated control of the two mechanisms can be achieved through a simple control system. This design not only improves the controllability of the equipment, but also reduces the difficulty and complexity of operation. Through the well-designed structure and component coordination, the present invention ensures the stability and reliability of the equipment. Even under long-term and high-intensity use, the equipment can maintain stable performance and accuracy. 3. The present invention also provides a centrifugal mechanism. The centrifugal mechanism provides an effective centrifugal effect for the die-casting process through a carefully designed structure and working principle, which helps to separate the gas or impurities in the mold during the die-casting process, thereby improving product quality and production efficiency. The mechanism has good stability and reliability, and provides a strong guarantee for the long-term stable operation of the equipment. Among them, the structural components of the centrifugal mechanism and the synchronous transmission mechanism have a certain degree of repeatability. This repeatability brings many advantages to production, including reduction in R&D costs, enhancement of material substitutability and improvement of practicality, which helps to reduce production costs and improve production efficiency.

DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0022] A die-casting device and a die-casting method for a high-strength and light-weight aluminum alloy structural member according to an embodiment of the present invention will be described below in conjunction with the accompanying drawings.

[0023] like Figure 1-Figure 10 As shown, a die-casting device for a high-strength and lightweight aluminum alloy structural part according to an embodiment of the present invention comprises: Workbench 1: fixed to the ground, with a horizontal reciprocating conveying mechanism 11 on the top, a die-casting frame 12 on the horizontal reciprocating conveying mechanism 11, an upper die 13, a lower die 14 and a metal tank 15 filled with molten metal are respectively arranged on the die-casting frame 12, wherein the upper die 13 and the lower die 14 are arranged on the same side up and down and on the same axis, a rotating shaft seat 16 is arranged on the top of the upper die 13 and is connected to the inside of the die cavity of the upper die 13, the metal tank 15 is arranged on the other side of the die-casting frame 12, a feed pipe 17 is arranged inside the metal tank 15, one end of the feed pipe 17 is connected to the bottom of the inner cavity of the metal tank 15, and the other end of the feed pipe 17 is rotatably connected to the inner wall of the rotating shaft seat 16 and is connected to the inside of the rotating shaft seat 16; Synchronous transmission mechanism 2: arranged in the die casting frame 12, and respectively connected with the upper die 13, the lower die 14 and the metal can 15, the synchronous transmission mechanism 2 and the horizontal reciprocating conveying mechanism 11 share the same motor 100 for driving; Pre-treatment mechanism 3: includes a heating rack 31, a release agent spray rack 32 and an air drying rack 33, which are arranged in sequence on the top of the workbench 1 in the horizontal direction and are located on one side of the die-casting rack 12. The die-casting rack 12 is symmetrically provided with tooth portions 18 on one side surface close to the heating rack 31, and the tooth portions 18 are respectively meshed and connected with the first toothed knob switches 34 on the heating rack 31, the release agent spray rack 32 and the air drying rack 33.

[0024] It should be noted that a cooling mechanism (not shown in the figure) is also provided inside the upper mold 13 and the lower mold 14 described in this embodiment.

[0025] It should also be noted that the horizontal reciprocating conveying mechanism 11 is a prior art and will not be described in detail here. The horizontal reciprocating conveying mechanism 11 is a horizontal reciprocating screw, and the die-casting frame 12 is threadedly connected to the outer surface of the horizontal reciprocating screw and horizontally slidably connected to the top of the workbench 1.

[0026] It is understandable that the heating rack 31 is a flamethrower rack, and the first toothed knob switch 34 of the heating rack 31 has an ignition switch. When the first toothed knob switch 34 is turned on, the ignition operation will be performed synchronously. The above is the prior art, so it will not be repeated here.

[0027] Specifically, the present invention has a reasonable structure. It adopts one power source to drive the entire system, which effectively reduces the production cost and reduces the difficulty of operation. This design not only simplifies the complexity of the system, but also makes subsequent maintenance and control work easier. Since the system structure is clear and the components are modular, the control and maintenance work can be carried out more quickly and efficiently. This design greatly improves the reliability and service life of the equipment. Among them, the use of electric drive makes the power source of the present invention have high popularity and easy replacement. Once a fault occurs, a replacement motor 100 can be quickly found for replacement, thereby greatly improving the maintenance efficiency and equipment availability.

[0028] When in use, the motor 100 is powered on and runs, and the operation of the motor 100 drives the horizontal reciprocating conveying mechanism 11 to start moving, and this mechanism then drives the die-casting frame 12 to move away from the motor 100. During the movement of the die-casting frame 12, the upper mold 13 and the lower mold 14 will pass through the heating frame 31, the release agent spraying frame 32 and the air drying frame 33 in sequence. These steps are mold preheating, spraying release agent and air drying, respectively, to prepare for the subsequent die-casting process. When the die-casting frame 12 stops moving, the motor 100 drives the synchronous transmission mechanism 2 to start running. First, this mechanism will drive the annular pressure frame 141 on the lower mold 14 to descend. When the annular pressure frame 141 descends, the ejector pin 143 will return to the needle groove. Then, the synchronous transmission mechanism 2 is operated to close the upper mold 13 and the lower mold 14 to form a mold cavity of the die-casting part. Then, the synchronous transmission mechanism 2 will open the metal can 1 5 and the second toothed knob switch 154 between the air pressure device, the liquid inside the metal can 15 is automatically injected into the mold cavity by pressurizing. After the injection is completed, the synchronous transmission mechanism 2 continues to operate, driving the upper mold 13 and the lower mold 14 to rotate synchronously, removing bubbles by centrifugal force, and improving the quality of the casting. After the cooling is completed, the synchronous transmission mechanism 2 is reset, the mold rotation is stopped first, and then the pressurization operation is stopped, and then the mold separation operation is performed, and finally separated from the annular pressing frame 141. After the annular pressing frame 141 is separated from the synchronous transmission mechanism 2, the ejector pin 143 is reset under the elastic force of the compression spring, and the material in the mold cavity of the lower mold 14 is ejected. After the material is ejected, the material can be removed manually or by an intelligent robotic arm. After the material is removed, the motor 100 drives the horizontal reciprocating conveying mechanism 11 to operate again, driving the die casting frame 12 to reset, so as to facilitate the next pre-processing operation.

[0029] In one embodiment of the present invention, Figure 2 As shown, the surface of the lower mold 14 is vertically slidably connected to an annular pressure frame 141, and a compression spring is fixedly connected to the surface of the lower mold 14, an annular guide groove 142 is opened on the top of the annular pressure frame 141, and the inner wall of the mold cavity of the lower mold 14 is vertically slidably connected to a ejector pin 143, and is connected to the annular pressure frame 141, and one end of the synchronous transmission mechanism 2 is located inside the annular guide groove 142 and is slidably connected to the inner wall of the annular guide groove 142.

[0030] It should be noted that, in order to reduce the impact force during mold closing, a buffer column and a guide column are respectively provided at the corresponding positions of the top of the lower mold 14 and the bottom of the upper mold 13.

[0031] Specifically, the structure and connection relationship of the lower mold 14 are further explained. Before the mold is closed, the annular pressure frame 141 will move downward due to the pressure from the synchronous transmission mechanism 2. This movement process will press down the compression spring and drive the ejector pin 143 to move downward together, thereby facilitating subsequent die-casting operations. When the die-casting material cools and solidifies into a workpiece, the synchronous transmission mechanism 2 separates from the annular pressure frame 141. Under the elastic force of the compression spring, it will drive the annular pressure frame 141 and the ejector pin 143 to move upward synchronously, thereby ejecting the workpiece from the mold cavity.

[0032] In this process, the annular guide groove 142 guides and positions the synchronous transmission mechanism 2, ensuring that the annular pressure frame 141 is uniformly stressed as a whole, and also facilitating subsequent sliding use.

[0033] In one embodiment of the present invention, Fig. 9 As shown, a accommodating chamber 151 is provided inside the metal can 15, a discharge groove 152 is vertically opened on one side of the accommodating chamber 151 and is connected to the inside of the accommodating chamber 151, one end of the feed pipe 17 is connected to the bottom of the inner cavity of the discharge groove 152 and is arranged coaxially with the discharge groove 152, an air pipe 153 is provided on the top of the metal can 15, one end of the air pipe 153 is connected to the inside of the accommodating chamber 151, and the other end of the air pipe 153 is connected to the air pressure generating device, and a second toothed knob switch 154 is provided on the surface of the air pipe 153, which is meshed and connected with one end of the synchronous transmission mechanism 2.

[0034] It should be noted that the metal can 15 described in this embodiment also has a heat preservation device (not shown in the figure).

[0035] It can be understood that a pressure relief pipe (not shown in the figure) is also provided on the top of the metal tank 15, and the pressure relief pipe is connected with the interior of the accommodating chamber 151. A third toothed knob switch (not shown in the figure) is provided on the pressure relief pipe. The third toothed knob switch (not shown in the figure) is used for pressure relief operation. The third toothed knob switch is located on one side of the top of the second toothed knob switch 154, and is meshed and connected with one end of the synchronous transmission mechanism 2. The synchronous transmission mechanism 2 first contacts the third toothed knob switch, thereby closing the third toothed knob switch, and then contacts the second toothed knob switch 154, and opens the second toothed knob switch 154, so that the inert gas enters the interior of the metal tank 15. When the synchronous transmission mechanism 2 is reset, it first drives the second toothed knob switch 154 to close, thereby realizing the pressure maintaining operation, and then drives the third toothed knob switch to open, thereby performing the pressure relief operation.

[0036] Specifically, the structure and connection relationship of the metal tank 15 are further explained. The metal tank 15 is used to store molten metal and keep the molten metal warm. When in use, the second toothed knob switch 154 is rotated. After the second toothed knob switch 154 is turned on, the air pressure generating device releases inert gas into the accommodating chamber 151 through the air pipe 153, forcing the internal pressure of the accommodating chamber 151 to increase. The inert gas in the accommodating chamber 151 presses the molten metal in the accommodating chamber 151 along the discharge groove 152 into the feed pipe 17, and then enters the rotating shaft seat 16 from the feed pipe 17, and finally enters the mold cavity of the upper mold 13 from the rotating shaft seat 16.

[0037] In one embodiment of the present invention, Figure 3 As shown, the synchronous transmission mechanism 2 includes a rotating key cylinder 21, a flat key rod 22, a first bevel gear 23, a reciprocating screw rod 24, a second bevel gear 25, a vertical guide seat 26, a vertical transmission rod 27, a first cam shaft 28, a second cam shaft 29, a third cam shaft 210, a pressurizing transmission mechanism 211, a mold clamping drive mechanism 212 and a needle withdrawal mechanism 213. The rotating key cylinder 21 is rotatably connected to the inner wall of the die-casting frame 12, the flat key rod 22 is horizontally slidably connected to the inner wall of the rotating key cylinder 21, both ends of the flat key rod 22 respectively pass through the outside of the rotating key cylinder 21, and are rotatably connected to the surface of the fixed seat arranged on the top of the workbench 1, one end of the flat key rod 22 passes through the outside of the fixed seat and is connected to the motor 100, the first bevel gear 23 is fixedly connected to the center of the surface of the rotating key cylinder 21, and is located inside the die-casting frame 12, the reciprocating screw rod 24 is vertically rotatably connected to the inner wall of the die-casting frame 12, and is located on one side of the top of the first bevel gear 23, and the second bevel gear 25 is fixedly connected to The reciprocating screw rod 24 is at the bottom and meshes with the first bevel gear 23. The vertical guide seat 26 is threadedly connected to the outer surface of the reciprocating screw rod 24 and vertically slidably connected to the inner wall of the die casting frame 12. The vertical transmission rod 27 is fixedly connected to the top of the vertical guide seat 26. The first convex shaft 28, the second convex shaft 29 and the third convex shaft 210 are sequentially arranged on the surface of the vertical transmission rod 27 along the vertical direction. The pressurizing transmission mechanism 211, the mold clamping drive mechanism 212 and the needle withdrawal mechanism 213 are arranged in the vertical direction according to the mold clamping drive mechanism 212. The first and second ends of the pressurizing transmission mechanism 211, the mold closing drive mechanism 212 and the needle withdrawal mechanism 213 are respectively connected to the first cam 28, the second cam 29 and the third cam 210, and the other ends of the pressurizing transmission mechanism 211, the mold closing drive mechanism 212 and the needle withdrawal mechanism 213 respectively pass through the outside of the die-casting frame 12 and are connected to the second toothed knob switch 154, the upper mold 13 and the annular press frame 141.

[0038] It should be noted that the inner wall of the rotating key cylinder 21 described in this embodiment and the surface position of the flat key rod 22 are respectively provided with keyways and transmission keys. The keyway and transmission key design can not only realize power transmission, but also facilitate its lateral movement, and the use effect is good.

[0039] Specifically, the structure and connection relationship of the synchronous transmission mechanism 2 are further explained. The synchronous transmission mechanism 2 is a complex and sophisticated mechanical system, which involves the coordinated work of multiple components to achieve specific functions. Through reasonable design and layout, these components can work together efficiently to meet various needs in the die-casting process.

[0040] The working principle of the synchronous transmission mechanism 2 involves the coordinated work of multiple components. When the motor 100 drives the straight key rod 22 to rotate, it will drive the rotating key cylinder 21 to rotate. The rotation of the rotating key cylinder 21 will drive the first bevel gear 23 to rotate, and then drive the second bevel gear 25 and the reciprocating screw 24 to rotate through meshing. The rotation of the reciprocating screw 24 will drive the vertical guide seat 26 to move up and down through the threaded connection, and then drive the vertical transmission rod 27 to move up and down. The up and down movement of the vertical transmission rod 27 will drive the pressurizing transmission mechanism 211, the mold closing drive mechanism 212 and the needle withdrawal mechanism 213 to perform corresponding movements through the cam shaft, thereby realizing specific functions, such as driving the ejector pin 143 to withdraw the needle, driving the upper mold 13 to close the mold, adjusting the air pressure to achieve injection, adjusting the air pressure to achieve pressure holding, driving the upper mold 13 to separate the mold, and driving the ejector pin 143 to eject the material.

[0041] In one embodiment of the present invention, Figure 4-Figure 6 As shown, the pressurizing transmission mechanism 211 includes a first rotating cylinder 2111, a first top gear 2112, a first spiral guide groove 2113, a first transmission gear 2114, a first threaded screw 2115, a first transmission slide 2116 and a driving gear seat 2117. The first rotating cylinder 2111 is rotatably connected to the inner wall of the die-casting frame 12 and is sleeved on the outer side of the vertical transmission rod 27. The first top gear 2112 is fixedly connected to the upper end surface of the first rotating cylinder 2111. A first spiral guide groove 2113 is provided on the surface of the first rotating cylinder 2111 at a position corresponding to the position of the first convex shaft 28. One end of the first convex shaft 28 is located inside the first spiral guide groove 2113 and slides with the inner wall of the first spiral guide groove 2113. The first transmission gear 2114 is rotatably connected to the inner wall of the die-casting frame 12 and meshes with the first top gear 2112. The first threaded screw 2115 is rotatably connected to the inner wall of the die-casting frame 12 and fixedly connected to the surface of the first transmission gear 2114. The first transmission slide 2116 is threadedly connected to the outer surface of the first threaded screw 2115 and vertically slidably connected to the inner wall of the die-casting frame 12. One end of the first transmission slide 2116 passes through the outside of the die-casting frame 12 and is vertically slidably connected to the surface of the die-casting frame 12. The driving gear seat 2117 is fixedly connected to the bottom of one end of the first transmission slide 2116 passing through the outside of the die-casting frame 12 and meshes with the second toothed knob switch 154. The mold closing drive mechanism 212 includes a second rotating cylinder 2121, a second top gear 2122, a second spiral guide groove 2123, a second transmission gear 2124, a second threaded screw 2125 and a second transmission slide 2126. The second rotating cylinder 2121 is rotatably connected to the inner wall of the die casting frame 12 and is sleeved on the outer side of the vertical transmission rod 27. The second top gear 2122 is fixedly connected to the upper end surface of the second rotating cylinder 2121. A second spiral guide groove 2123 is provided on the surface of the second rotating cylinder 2121 at a position corresponding to the position of the second cam shaft 29. One end of the second cam shaft 29 is located inside the second spiral guide groove 2123 and is slidably connected to the inner wall of the second spiral guide groove 2123. The second transmission gear 2124 is rotatably connected to the die casting frame 12. The second threaded screw 2125 is rotatably connected to the inner wall of the die casting frame 12 and is fixedly connected to the surface of the second transmission gear 2124. The second transmission slide 2126 is threadedly connected to the outer surface of the second threaded screw 2125 and is vertically slidably connected to the inner wall of the die casting frame 12. One end of the second transmission slide 2126 passes through the outside of the die casting frame 12 and is vertically slidably connected to the surface of the die casting frame 12. The upper mold 13 is fixedly connected to the bottom of one end of the second transmission slide 2126 passing through the outside of the die casting frame 12 and is coaxially arranged with the lower mold 14. The top of the rotating shaft seat 16 passes through the top of the second transmission slide 2126 and is connected to the feed pipe 17. The needle withdrawal mechanism 213 includes a third rotating cylinder 2131, a third top gear 2132, a third spiral guide groove 2133, a third transmission gear 2134, a synchronous toothed belt 2135, a third threaded screw 2136, an L-shaped support arm 2137 and a limit rod 2138. The third rotating cylinder 2131 is rotatably connected to the inner wall of the die-casting frame 12 and is sleeved on the outer side of the vertical transmission rod 27. The third top gear 2132 is fixedly connected to the upper end surface of the third rotating cylinder 2131. A third spiral guide groove 2133 is provided at a position on the surface of the third rotating cylinder 2131 corresponding to the position of the third cam shaft 210. One end of the third cam shaft 210 is located inside the third spiral guide groove 2133 and is slidably connected to the inner wall of the third spiral guide groove 2133. The third transmission gear 2134 is symmetrically rotatably connected to the inner wall of the die-casting frame 12, and is connected to the second top gear 2122 through a synchronous toothed belt 2135. The third threaded screw 2136 is rotatably connected to the inner wall of the third transmission gear 2134. The L-shaped support arm 2137 is vertically slidably connected to the inner wall of the die-casting frame 12, and is fixedly connected to the bottom of the third threaded screw 2136. One end of the L-shaped support arm 2137 passes through the outside of the die-casting frame 12 and is vertically slidably connected to the surface of the die-casting frame 12. The limit rod 2138 is fixedly connected to the bottom of one end of the L-shaped support arm 2137 that passes through the outside of the die-casting frame 12. One end of the limit rod 2138 is located inside the annular guide groove 142 and is slidably connected to the inner wall of the annular guide groove 142.

[0042] It should be noted that the needle withdrawal mechanism 213 described in this embodiment also includes an auxiliary wheel (not shown in the figure), which is symmetrically rotatably connected to the inner wall of the die-casting frame 12 and is located on the outside of the third top gear 2132. The auxiliary wheel is used to adjust the transmission angle and contact area between the synchronous belt 2135 and the third transmission gear 2134 and the third top gear 2132, so that the wrap angle and contact area can meet the power transmission requirements.

[0043] It can be understood that in order to realize the sequential operation of the needle withdrawal mechanism 213, the mold closing drive mechanism 212 and the pressurizing transmission mechanism 211, the positions of the spiral segments in the three groups of third spiral guide grooves 2133 need to be set, wherein the spiral segment in the third spiral guide groove 2133 in the needle withdrawal mechanism 213 is located at the overall upper end of the third spiral guide groove 2133, the spiral segment in the third spiral guide groove 2133 in the mold closing drive mechanism 212 is located at the overall middle end of the third spiral guide groove 2133, and the spiral segment in the third spiral guide groove 2133 in the pressurizing transmission mechanism 211 is located at the overall lower end of the third spiral guide groove 2133. By setting the contact time of the first cam 28, the second cam 29 and the third cam 210 with the three groups of spiral segments, the operating sequence and time of the needle withdrawal mechanism 213, the mold closing drive mechanism 212 and the pressurizing transmission mechanism 211 can be accurately controlled. This setting method ensures the coordination and efficiency of each mechanism during the die-casting process.

[0044] Specifically, the structures and connection relationship of the pressurized transmission mechanism 211, the mold-closing drive mechanism 212 and the needle-retracting mechanism 213 are further explained. The pressurized transmission mechanism 211, the mold-closing drive mechanism 212 and the needle-retracting mechanism 213 ensure the high efficiency, coordination and flexibility of the die-casting process through the carefully designed structure and working principle. This design not only improves the production efficiency, but also reduces the maintenance cost, and provides strong support for the wide application of die-casting equipment. The pressurized transmission mechanism 211, the mold-closing drive mechanism 212 and the needle-retracting mechanism 213 are respectively used for adjusting the air pressure to realize injection, adjusting the air pressure to realize pressure holding, driving the upper mold 13 to close the mold, driving the upper mold 13 to separate the mold, driving the ejector pin 143 to withdraw the needle and driving the ejector pin 143 to eject the material.

[0045] When the vertical transmission rod 27 is raised or lowered, the first rotating cylinder 2111 is driven to rotate through the sliding connection between the first convex shaft 28 and the first spiral guide groove 2113, and the first top gear 2112 rotates accordingly and meshes with the first transmission gear 2114, thereby driving the first threaded screw 2115 to rotate. The first transmission slide 2116 slides vertically due to the threaded connection on the first threaded screw 2115. The movement of the first transmission slide 2116 synchronously drives the driving gear seat 2117 to move. During the movement of the driving gear seat 2117, it meshes with the second toothed knob switch 154 and opens the second toothed knob switch 154, allowing the inert gas to enter the interior of the metal can 15.

[0046] When the vertical transmission rod 27 is raised or lowered, the second rotating cylinder 2121 is driven to rotate through the sliding connection between the second convex shaft 29 and the second spiral guide groove 2123, and the second top gear 2122 rotates accordingly and engages with the second transmission gear 2124, thereby driving the second threaded screw 2125 to rotate. The second transmission slide 2126 slides vertically due to the threaded connection on the second threaded screw 2125. The lifting and lowering of the second transmission slide 2126 synchronously drives the upper mold 13 to move, thereby realizing the mold closing and mold opening operations.

[0047] When the vertical transmission rod 27 is raised or lowered, the third rotating drum 2131 is driven to rotate through the sliding connection between the third cam shaft 210 and the third spiral guide groove 2133. The rotation of the third rotating drum 2131 synchronously drives the third top gear 2132 downward. The rotation of the third top gear 2132 drives the two groups of third transmission gears 2134 to rotate respectively through the synchronous toothed belt 2135. The rotation of the third transmission gear 2134 drives the third threaded screw 2136 and the L-shaped support arm 2137 to move downward. The downward movement of the L-shaped support arm 2137 synchronously drives the limit rod 2138 to move downward, and enters the annular guide groove 142, and drives the annular pressure frame 141 and the ejector pin 143 to descend, thereby realizing the needle withdrawal operation.

[0048] All three mechanisms are driven by the lifting and lowering of the vertical transmission rod 27, but each realizes independent motion control through different cam shafts and spiral guide grooves. This design ensures the coordination between the mechanisms while allowing each to operate independently. Through the cooperation of the threaded screw, the transmission slide and the L-shaped support arm 2137, fast and stable pressurization, mold closing and needle withdrawal actions are achieved. This design improves the efficiency of the die-casting process. By adjusting the second toothed knob switch 154 and other components, the pressurization state can be flexibly adjusted, which increases the flexibility of the equipment. Each mechanism component is designed to be easy to disassemble and reinstall, which is convenient for maintenance and replacement.

[0049] In one embodiment of the present invention, Figure 6 As shown, the bottom of the limiting rod 2138 is threadedly connected to an annular ring frame 2139 and is sleeved on the outside of the lower mold 14. A ball is arranged at the bottom of the annular ring frame 2139, and the ball is slidably connected to the inner wall of the annular guide groove 142.

[0050] Specifically, by threading the bottom of the limit rod 2138 to the annular ring frame 2139 and sleeved on the outside of the lower mold 14, and then coordinating the sliding connection between the ball and the annular guide groove 142, not only stable vertical movement is achieved, but also the accuracy and smoothness of the movement are improved. This design not only meets the high requirements for the needle withdrawal mechanism 213 during the die-casting process, but also provides a strong guarantee for the long-term stable operation of the equipment.

[0051] In one embodiment of the present invention, Figure 7As shown, the lower mold 14 also includes a centrifugal mechanism 214, which includes a rotating platform 2141, an upper gear 2142, a lower gear 2143, a first one-way transmission device 2144, a fourth drum 2145, a lower end gear 2146, a shaft 2147, a fourth cam 2148, a fourth spiral guide groove 2149, a reset spring 21410, a bracket 21411 and a pressing rod 21412. The rotating platform 2141 is rotatably connected to the surface of the die-casting frame 12, and the lower mold 14 is fixedly connected to the top of the rotating platform 2141. The upper gear 2142 and the lower gear 2143 are respectively rotatably connected to the inner wall of the die-casting frame 12 and are connected through the first one-way transmission device 2144. The upper gear 2142 is meshed with the rotating platform 2141. The fourth drum 2145 is rotatably connected to the inner wall of the die-casting frame 12, and the lower end gear 2146 is fixedly connected to the lower end surface of the fourth drum 2145. And it meshes with the lower gear 2143, the shaft rod 2147 is vertically slidably connected to the inner wall of the fourth rotating cylinder 2145, and the fourth cam 2148 and the fourth spiral guide groove 2149 are respectively provided at the corresponding positions of the surface of the shaft rod 2147 and the inner wall of the fourth rotating cylinder 2145, one end of the fourth cam 2148 is located inside the fourth spiral guide groove 2149 and is slidably connected to the inner wall of the fourth spiral guide groove 2149, the bracket 21411 is fixedly connected to the surface of the vertical transmission rod 27, and is located on one side of the bottom of the third rotating cylinder 2131, the pressing rod 21412 is fixedly connected to the bottom of the bracket 21411 and corresponds to the position of the shaft rod 2147, one end of the shaft rod 2147 passes through the bottom of the fourth rotating cylinder 2145, and is fixedly connected to the inner wall of the die-casting frame 12 with a reset spring 21410, and the other end of the shaft rod 2147 passes through the top of the fourth rotating cylinder 2145 and contacts with the bottom of the pressing rod 21412.

[0052] It should be noted that the first one-way transmission 2144 described in this embodiment is a ratchet one-way transmission.

[0053] Specifically, the structure and connection relationship of the centrifugal mechanism 214 are further explained. The centrifugal mechanism 214 provides an effective centrifugal effect for the die-casting process through a carefully designed structure and working principle, which helps to separate the gas or impurities in the mold during the die-casting process, thereby improving product quality and production efficiency. At the same time, the mechanism also has good stability and reliability, providing a strong guarantee for the long-term stable operation of the equipment.

[0054] In the initial stage of the die-casting process, the centrifugal mechanism 214 is in a stationary state, and the shaft 2147 is maintained in the upper position under the action of the return spring 21410, and the fourth cam 2148 is located at the top of the fourth spiral guide groove 2149. The vertical transmission rod 27 descends and synchronously drives the bracket 21411 and the pressing rod 21412 to descend. At this time, all three groups of cams are in the vertical section of the spiral guide groove, that is, the pressing rod 21412 only contacts the top of the shaft 2147 after all three groups of cams have passed through the spiral sections of the three groups of spiral guide grooves. This helps to achieve centrifugal operation after injection. After the pressing rod 21412 contacts the top of the shaft 2147, it will synchronously squeeze the shaft 2147 to move downward. The downward movement of the shaft 2147 synchronously drives the fourth cam 2148 to slide in the fourth spiral guide groove 2149 and compress the return spring 21410. The fourth cam 2148 is in the fourth spiral guide groove 2149. The sliding will synchronously drive the fourth rotating drum 2145 and the lower end gear 2146 to rotate, and the rotation of the lower end gear 2146 will synchronously drive the lower gear 2143 to rotate. The rotation of the lower gear 2143 will synchronously drive the upper gear 2142 to rotate through the first one-way transmission device 2144, thereby driving the rotating platform 2141 and the lower mold 14 to perform centrifugal movement. Since the lower mold 14 and the upper mold 13 are connected through the buffer column and the guide column rod, it will synchronously drive the upper mold 13 and the rotating shaft seat 16 to rotate. When the pressing rod 21412 is separated from the contact shaft rod 2147, the reset spring 21410 will drive the shaft rod 2147 to reset to the initial height, which will cause the fourth cam 2148 to slide in the fourth spiral guide groove 2149, but due to the limitation of the first one-way transmission device 2144, the upper gear 2142 will not rotate in the opposite direction, thereby keeping the rotating platform 2141 and the lower mold 14 in a stationary state.

[0055] In one embodiment of the present invention, Figure 8 As shown, the motor 100 also includes a transmission frame 101, and the surface of the transmission frame 101 is symmetrically provided with a second one-way transmission device 102, and the inner wall of the transmission frame 101 is symmetrically rotatably connected with a driving gear 103 and meshed with each other, one end of two groups of second one-way transmission devices 102 are respectively connected to one end of the central axis of the driving gear 103, and the other ends of the two groups of second one-way transmission devices 102 are respectively connected to one end of the horizontal reciprocating conveying mechanism 11 and one end of the straight key rod 22, and the output shaft of the motor 100 is fixedly connected to the central axis of one group of driving gears 103; The transmission directions of the two sets of second one-way transmission devices 102 are opposite; An encoder 104 is disposed on the surface of the motor 100 .

[0056] It should be noted that the second one-way transmission 102 described in this embodiment is a ratchet one-way transmission.

[0057] It should also be noted that a controller 10 is provided at one end of the workbench 1 described in this embodiment close to the air-drying rack 33, and the motor 100 and the encoder 104 are respectively connected to the controller 10 through a bus system to realize data transmission and reception of control instructions, wherein the controller 10 has its own timing module.

[0058] It can be understood that the encoder 104 is used to monitor the number of rotations of the motor 100 in real time and send the number of rotations data to the controller 10. The controller 10 determines the positions of the die-casting frame 12, the drive gear seat 2117, the second transmission slide 2126 and the pressing rod 21412 based on the number of rotations data.

[0059] Specifically, the motor 100 is the core power source of the entire die-casting device. Its design not only effectively reduces the production cost, but also greatly facilitates the control and subsequent maintenance work, thereby ensuring excellent use effect.

[0060] During operation, the motor 100 actively responds to the command to start, and its rotational power is first transmitted to a set of drive gears 103. The rotation of this set of gears then drives another set of drive gears 103 meshing therewith to rotate synchronously. It is worth noting that the two sets of gears are respectively connected to two sets of second one-way transmission devices 102 with opposite transmission directions. This design ensures that power can only be transmitted in one direction. Therefore, at any time, the rotation of the two sets of drive gears 103 can only drive one set of the horizontal reciprocating conveying mechanism 11 or the one-way key rod 22 to rotate.

[0061] In order to realize the flexible switching of power, the forward and reverse control of the motor 100 is particularly important. When the motor 100 rotates forward, the power drives the horizontal reciprocating conveying mechanism 11 to rotate through a specific transmission path to complete the conveying and positioning tasks of the mold. When the motor 100 rotates reversely, the power is switched to another transmission path to drive the key rod 22 to rotate and perform other actions such as mold opening and closing. This design not only improves the flexibility of the device, but also effectively avoids power conflicts and energy waste.

[0062] The motor 100 and its precise transmission system together constitute the power core of the die-casting device, and flexible switching and efficient use of power can be achieved through simple forward and reverse control.

[0063] In one embodiment of the present invention, Fig.10 As shown, the first toothed knob switch 34 on the heating rack 31, the release agent spray rack 32 and the air drying rack 33 also includes a third one-way transmission device 341. The three groups of third one-way transmission devices 341 have the same transmission direction. The heating rack 31, the release agent spray rack 32 and the air drying rack 33 are respectively provided with joints 35. The heating rack 31, the release agent spray rack 32 and the air drying rack 33 are respectively connected to the gas pipe end, the release agent pipe end and the compressed air pipe end through the joints 35.

[0064] It should be noted that the third one-way transmission 341 described in this embodiment is a ratchet one-way transmission.

[0065] Specifically, the third one-way transmission 341 is cleverly arranged on the first toothed knob switch 34. Its main purpose is to prevent the first toothed knob switch 34 from being accidentally driven to perform opening and closing operations due to the movement of the tooth portion 18 during the resetting process of the die-casting rack 12. If there is no restriction of the third one-way transmission 341, such movement may trigger the first toothed knob switch 34, resulting in the accidental start or stop of operations such as preheating, spraying of release agent or air drying. The setting of the third one-way transmission 341 effectively avoids such misoperation. The third one-way transmission 341 only allows power to be transmitted in a specific direction, which means that the first toothed knob switch 34 will only be accurately driven when operations such as preheating, spraying of release agent or air drying are required. This design improves the accuracy and reliability of the operation. Accidental opening and closing operations may cause damage or wear to equipment such as the heating rack 31, the release agent spray rack 32 and the air drying rack 33. The setting of the one-way transmission reduces this risk, thereby extending the service life of the equipment.

[0066] The connector 35 is a key component that connects the heating rack 31, the release agent spray rack 32 and the air drying rack 33 with the corresponding pipelines. The connector 35 allows fluids such as fuel (such as gas), chemicals (such as release agents) and compressed air to be transported to the corresponding equipment through pipelines. This design ensures that operations such as heating, spraying release agents and air drying can obtain the required fluid supply.

[0067] A die-casting method for a high-strength and tough lightweight aluminum alloy structural part, applied to the above die-casting device for a high-strength and tough lightweight aluminum alloy structural part, comprises the following steps: S1: Pretreatment stage: The motor 100 is powered on and runs, and the motor 100 drives the horizontal reciprocating conveying mechanism 11 to start moving, and this mechanism then drives the die-casting frame 12 to move away from the motor 100. During the movement of the die-casting frame 12, the upper mold 13 and the lower mold 14 will pass through the heating frame 31, the release agent spraying frame 32 and the air drying frame 33 in sequence. These steps are mold preheating, spraying the release agent and air drying, respectively, to prepare for the subsequent die-casting process; S2: Die-casting stage: When the die-casting frame 12 stops moving, the motor 100 drives the synchronous transmission mechanism 2 to start running. First, this mechanism will drive the annular pressure frame 141 on the lower mold 14 to descend. When the annular pressure frame 141 descends, the ejector pin 143 will return to the needle groove. Then, the synchronous transmission mechanism 2 will operate to close the upper mold 13 and the lower mold 14 to form a mold cavity for the die-cast part. Then, the synchronous transmission mechanism 2 will open the second toothed knob switch 154 between the metal can 15 and the air pressure device, and the liquid inside the metal can 15 will be automatically injected into the mold cavity by pressurizing. After the injection is completed, the synchronous transmission mechanism 2 continues to operate, driving the upper mold 13 and the lower mold 14 to rotate synchronously, removing bubbles through centrifugal force to improve the quality of the casting. After the cooling is completed, the synchronous transmission mechanism 2 is reset, the mold rotation is stopped first, and then the pressurization operation is stopped, and then the mold separation operation is performed, and finally the annular pressing frame 141 is separated. After the annular pressing frame 141 is separated from the synchronous transmission mechanism 2, the ejector pin 143 is reset under the elastic force of the compression spring, and the material in the cavity of the lower mold 14 is ejected. After the material is ejected, the material can be removed manually or by an intelligent robotic arm; S3: Reset stage: After the material is removed, the motor 100 drives the horizontal reciprocating conveying mechanism 11 to operate again, driving the die-casting frame 12 to reset, so as to facilitate the next pre-processing operation.
