Description

Technical Field

[0001] This invention relates to the field of die-casting tool technology, and in particular to a die-casting apparatus for producing high-strength and tough parts for aluminum pots. Background Technology

[0002] As a widely used kitchen utensil in daily cooking, the forming quality of its high-strength and tough components (such as lids and rim reinforcements) directly affects the overall service life, structural stability, and safety of aluminum pots. With consumers' increasing demands for the durability and consistency of kitchen utensils, the market has set higher standards for the production precision, mechanical properties, and production efficiency of high-strength and tough components for aluminum pots.

[0003] Currently, traditional die-casting equipment used for aluminum pot parts production suffers from numerous technical defects in practical applications, severely hindering the improvement of product quality and production efficiency. In the parts forming stage, during the transfer of molten aluminum from the molten state to the mold cavity, rapid heat loss leads to a drop in temperature and decreased fluidity, resulting in incomplete filling and forming defects. Furthermore, traditional die casting often employs a one-time rapid stamping method, which easily generates turbulence when the molten aluminum fills the mold cavity, leading to defects such as porosity and inclusions inside the formed parts, poor structural uniformity, and difficulty in achieving high strength and toughness standards. Moreover, in the mold cleaning stage, there is a lack of a dynamic cleaning mechanism adapted to mold temperature. The cleaning fluid spray flow rate is fixed; if the mold temperature is too high and the spray intensity is too great, thermal stress can easily cause mold cracking. If the spray intensity is insufficient, residual aluminum slag and impurities in the mold cavity cannot be completely removed. In the drying stage, traditional air jet structures are mostly designed with a fixed angle, which cannot fully cover the complex curved surfaces of the mold cavity, resulting in cleaning fluid residue, which in turn affects the surface quality and forming effect of the next die-cast product. Therefore, these problems need to be addressed. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention achieves high-precision forming of high-strength and tough aluminum pot parts through the cooperation of heating and guiding components, stamping components, and mold devices. It not only continuously heats the molten aluminum in the inlet pipe during the die-casting stage to compensate for temperature loss during transportation, but also prevents molten aluminum from entering the cavity and flowing back during non-stamping processes, thanks to the one-way stage and springs inside the one-way pipe. Furthermore, the slow extrusion of the stamping components achieves venting and impurity removal and material densification of the molten aluminum before rapid stamping into the mold cavity, solving the problems of molten aluminum cooling, air entrapment, inclusions, and turbulent flow during traditional die casting. The guide rods and guide rails precisely guide and limit the moving and fixed mold bases, while the ejector plate ensures smooth demolding, improving the forming accuracy and structural uniformity of the parts, significantly reducing the defect rate, and ensuring product consistency.

[0017] 2. The device of this invention, through the cooperation of the collection and cleaning components, realizes the automated material handling, cleaning and drying after die casting, completing the clamping, transfer and placement of materials, replacing manual operation and improving production efficiency; the temperature control array composed of temperature sensors monitors the mold cavity temperature in real time and dynamically adjusts the spray flow rate of the high-pressure atomizing nozzle to avoid thermal stress causing mold damage or incomplete cleaning; through the drive motor, eccentric wheel, connecting rod, first connecting block and second connecting block, the high-pressure jet nozzle can achieve multi-angle swing, preventing residual cleaning liquid from affecting subsequent die casting and extending the service life of the mold.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Example 1: See Figures 1 to 10This invention discloses a die-casting apparatus for producing high-strength and tough aluminum pot fittings. It includes a first positioning platform, a second positioning platform mounted on one side of the first positioning platform, and a drive chamber within the second positioning platform. The first and second positioning platforms form the support structure for the entire die-casting equipment. A hydraulic device 1 is mounted on one side of the second positioning platform to provide hydraulic pressure to the entire equipment. This hydraulic device 1 serves as the supply device for the hydraulic components within the die-casting apparatus, ensuring stable operation. A control module 2 for operating the entire equipment is vertically mounted at the front end of one side of the first positioning platform. This control module 2 coordinates with an external control system to control the operation of the entire die-casting equipment and allows for program modifications based on different process requirements. The control module 2 includes a physical button module and a touchscreen module. The physical button module has higher priority than any device or component of the die-casting equipment. The physical button module includes common buttons such as power-on and emergency stop buttons, as well as knobs. A mold device for producing aluminum pot lids is installed inside the first positioning platform. A heating guide component for optimizing the forming of the aluminum pot lid is mounted below one side of the mold device. A cleaning device for the mold and a collection and cleaning assembly for clamping the moving aluminum pot lid are installed on one side of the top surface of the platform. A stamping assembly for adapting to the heating guide assembly and providing stamping for the mold assembly is installed inside the second positioning platform. Guide rods 3 are equidistantly installed laterally at the four corners of the first positioning platform. These guide rods 3 facilitate subsequent guidance and support for the moving mold base 9 inside the mold assembly in conjunction with the first support platform 5. The guide rods 3 also facilitate the fixing of the ejector plate 8 in conjunction with external limiting components. Furthermore, guide rails 4 are laterally installed at both the front and rear ends of the bottom surface of the first positioning platform, allowing for... The first support platform 5 and the second support platform 6 are slidably connected to the external limiting components. The first support platform 5 and the second support platform 6 are slidably connected between the two guide rails 4 respectively. The first support platform 5 facilitates the limiting of the moving mold base 9 with the external limiting components and provides support for the moving mold base 9. The second support platform 6 facilitates the limiting of the fixed mold base 11 with the external limiting components. The fixed mold base 11 needs to be positioned relative to the first support platform 5 with the external limiting components. The fixed mold base 11 is positioned with the external limiting components and does not slide relative to the guide rails 4.

[0032] Reference Figures 2 to 3As shown, the mold assembly includes a first hydraulic cylinder 7 horizontally mounted on the inner wall of the other side of the first positioning platform. The first hydraulic cylinder 7 facilitates the subsequent closing and separation of the moving mold base 9 and the moving mold 10 relative to the fixed mold 12. An ejector plate 8 adapted to the guide rod 3 is installed inside the first positioning platform. The ejector plate 8 facilitates the ejector pins to push out the die-cast mold placed in the first mold groove when the moving mold 10 is reset. A sliding groove is opened in the middle of the ejector plate 8 for the sliding of the output shaft of the first hydraulic cylinder 7. The sliding groove helps to prevent the output shaft of the first hydraulic cylinder 7 from sliding during operation. When moving, it interferes with the ejector plate 8, thus damaging the ejector plate 8; and the other side of the ejector plate 8 is slidably connected to a moving mold base 9 adapted to the first support platform 5 and the guide rod 3. The moving mold base 9 has multiple first limiting grooves equidistantly opened on one side. The moving mold base 9 facilitates the installation and limiting of the moving mold 10 through the first limiting grooves and in cooperation with the external limiting component. The moving mold base 9 opens the first limiting grooves according to the installation structure of the moving mold 10 and in cooperation with the external grooving component; and the moving mold 10 that matches the first limiting groove is installed on one side of the moving mold base 9. The moving mold 10 has multiple first limiting grooves equidistantly opened on one side of the moving mold base 9. The mold has multiple first mold slots. The moving mold 10 facilitates the shaping of the aluminum pot lid by cooperating with the first mold slots and the second mold slots opened in the fixed mold 12. The moving mold 10 is opened with the first mold slots by an external machine tool. Multiple ejector pins that are adapted to the first mold slots are installed at equal intervals on one side of the ejector plate 8. The moving mold base 9 and the other side of the moving mold 10 are both connected and have ejector grooves that are adapted to the sliding of the ejector pins. The ejector pins are used to guide and limit the ejector pins. A fixed mold base 11 adapted to the second support platform 6 and the guide rod 3 is installed on one side of the moving mold 10. Multiple ejector pins that are adapted to the first mold slots are opened at equal intervals on the other side of the fixed mold base 11. The second limiting groove is provided, and a fixed mold 12 adapted to the second limiting groove is installed on the other side of the fixed mold base 11. The fixed mold 12 is provided with a second mold groove adapted to the first mold groove at equal intervals on the other side. The fixed mold base 11 facilitates the installation of the fixed mold 12 through the second limiting groove and in conjunction with the external limiting component. The fixed mold base 11 opens the second limiting groove in conjunction with the external grooving component according to the installation structure of the fixed mold 12. A connecting platform connecting to the second mold groove is installed in the lower middle part of one side of the fixed mold 12. The connecting platform facilitates the installation of the one-way tube 13 in conjunction with the external limiting component.

[0033] Example 2: The technical solution is basically the same as that of Example 1, except that, as Figure 2 , Figure 3 , Figure 7As shown, the heating guide assembly includes a one-way pipe 13 placed horizontally within the second positioning platform and connected at one end to the connecting platform. The one-way pipe 13 serves as a guide for the molten aluminum to enter the first and second mold slots during the die-casting process. The one-way pipe 13 is further integrated with the inlet pipe 14, electromagnetic coil 15, and stamping assembly in subsequent processes. Compared to the traditional process, the new process, during die-casting, involves the molten aluminum entering the inlet pipe 14 through the inlet groove. Then, the fourth hydraulic cylinder 18 is activated to slowly move and compress the accumulated molten aluminum using the impact rod 20. At this time, the molten aluminum maintains a predetermined liquid state under the heating of the electromagnetic coil 15. Simultaneously, the one-way platform 23 within the one-way pipe 13 prevents the molten aluminum from entering the one-way pipe 13. After the molten aluminum compensates for the temperature loss caused by external movement, the impact rod 20 is quickly activated to perform die-casting. This process ensures... The stable aluminum liquid temperature and slow extrusion achieve gas degassing, impurity removal, and material densification before stable die casting, solving the four core problems of aluminum liquid cooling, air entrapment, inclusions, and turbulent flow during filling in traditional die casting from the source. A liquid inlet pipe 14 is installed at the other end of the unidirectional pipe 13, and a liquid inlet groove is opened on the outer side of the other end of the liquid inlet pipe 14. The liquid inlet pipe 14 facilitates the use of an external robotic arm to collect the aluminum liquid to be die-cast in a crucible. The liquid inlet pipe 14 is used in conjunction with an external grooving process to create the liquid inlet groove. Furthermore, electromagnetic coils 15 for pipe heating are wound equidistantly on the outer side of one end of the liquid inlet pipe 14. The electromagnetic coils 15 facilitate the heating of the aluminum liquid inside the liquid inlet pipe 14, compensating for the temperature loss caused by external operation. The electromagnetic coils 15 should be connected to the control system and temperature monitoring system, and are linked with the temperature control system using closed-loop control to monitor the aluminum liquid temperature in real time and adjust the heating power accordingly.

[0034] Reference Figures 1 to 5 As shown, a one-way hole is provided on one side of the one-way tube 13, and a positioning plate 21 is installed on one side inside the one-way tube 13. The positioning plate 21 facilitates the installation of the telescopic platform 22 in conjunction with the external limiting component. The telescopic platform 22 is horizontally installed on one side of the middle of the positioning plate 21. The telescopic platform 22 has a slot, which facilitates the sliding of the one-way rod. The telescopic platform 22 is designed to fit the slot with the external grooving component. The telescopic platform 22 is slidably connected to a one-way rod with a T-shaped structure that is adapted to the slot for limiting. The one-way rod facilitates the installation of the external limiting component. The welding process of the part is fixed to the one-way stage 23, and together with the one-way stage 23 and the spring 24, a one-way structure is formed. This one-way structure prevents the aluminum liquid from flowing back into the liquid inlet pipe 14 during the die casting process and is conducive to the normal operation of the new process. One end of the one-way rod is fixed to the one-way stage 23 for sealing the one-way hole. The one-way stage 23 facilitates the sealing of the one-way hole with the spring 24. The spring 24 is installed horizontally in the hole groove. The other end of the spring 24 is fixed to the other end face of the one-way rod. The spring 24 facilitates the provision of driving force for the one-way rod after reset.

[0035] Reference Figures 2 to 3As shown, the stamping assembly includes a second hydraulic cylinder 51 vertically mounted on the other side of the bottom surface of the hydraulic device 1 and connected to the second positioning platform. A third hydraulic cylinder 16, adapted to the second hydraulic cylinder 51, is vertically mounted in the center of the floor of the drive chamber. The output shaft of the third hydraulic cylinder 16 passes through the second positioning platform, and a limiting platform 17 is installed on the output shaft of the third hydraulic cylinder 16. The second hydraulic cylinder 51 and the third hydraulic cylinder 16 facilitate the simultaneous adjustment of the horizontal height of the hydraulic device 1 and the fourth hydraulic cylinder 18, thereby adjusting the adaptation height of the impact rod 20 and the inlet pipe 14 to ensure the stability of the die casting process. A fourth hydraulic cylinder, adapted to the limiting platform 17, is horizontally mounted in the center of the lower part of the other side of the hydraulic device 1. Hydraulic cylinder 18, through which the fourth hydraulic cylinder 18 cooperates with coupling block 19 to drive the impact rod 20 to move, the output shaft of the fourth hydraulic cylinder 18 is fitted with limiting coupling block 19 through an external limiting component; the output shaft of the fourth hydraulic cylinder 18 is sleeved with coupling block 19, through which the fourth hydraulic cylinder 18 and the impact rod 20 are connected; the second hydraulic cylinder 51 adjusts the overall height of the hydraulic device 1, and the third hydraulic cylinder 16 finely adjusts the height of the limiting platform 17, the two cooperate to make the impact rod 20 accurately aligned with the liquid inlet pipe 14; the other end of the coupling block 19 is equipped with an impact rod 20 adapted to the liquid inlet pipe 14, through which the impact rod 20 is used to impact the aluminum liquid in the liquid inlet pipe 14 during the die casting process of aluminum liquid.

[0036] Example 3: The technical solution is basically the same as that of Example 1, except that, as Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 10 As shown, the collection and cleaning assembly includes a support frame 25 mounted on the top surface of the first positioning platform. The support frame 25 facilitates the installation and positioning of the first linear motor 26 in conjunction with an external limiting component. The first linear motor 26 is longitudinally mounted on one side of the top surface of the support frame 25, which facilitates the movement of the counterweight platform 27 along the X-axis. The first linear motor 26 limits the counterweight platform 27 to the top surface of the output plate via an external limiting component. The counterweight platform 27 is laterally mounted on the top surface of the output plate of the first linear motor 26. The counterweight platform 27 has a horizontally formed mounting groove, which facilitates the installation of the counterweight platform 27 in conjunction with the external limiting component. The component installation limits the second linear motor 28, and the counterweight platform 27 cooperates with the external slotting component to open the installation slot; the second linear motor 28 is installed in the installation slot, and the output plate of the second linear motor 28 is placed on the top surface of the counterweight platform 27. The second linear motor 28 facilitates the movement of the locking platform 29 in the Y-axis direction, and cooperates with the external limiting component to connect the locking platform 29 to the output plate of the second linear motor 28; and the locking platform 29 is vertically installed on the top surface of the output shaft of the second linear motor 28. The locking platform 29 facilitates the installation and limiting of the third linear motor 30 and the fourth linear motor 31 in cooperation with the external limiting component.

[0037] Reference Figures 3 to 9 As shown, a third linear motor 30 is vertically mounted at the front end of the locking platform 29. The third linear motor 30 facilitates the movement of the second limiting rod 35 in the Z-axis direction and, in conjunction with an external limiting component, connects the second limiting rod 35 to the output plate of the third linear motor 30. A fourth linear motor 31 is vertically mounted at the rear end of the locking platform 29. The fourth linear motor 31 facilitates the movement of the first limiting rod 32 in the Z-axis direction and, in conjunction with an external limiting component, connects the first limiting rod 32 to the output plate of the fourth linear motor 31. The output plate of the fourth linear motor 31 is equipped with an L-shaped first limiting device. The first limiting rod 32 has a locking groove at one end. The first limiting rod 32, in conjunction with the locking groove and an external limiting component, facilitates the limiting of the stepper motor 33. The locking groove is formed by the first limiting rod 32 and the external grooving component. The stepper motor 33 is installed within the locking groove. The stepper motor 33, in conjunction with an external connecting component, connects to the limiting flexible gripper 34 and drives the flexible gripper 34 to rotate during subsequent material feeding. The output shaft of the stepper motor 33 is equipped with a pneumatic flexible gripper 34, which facilitates the clamping of the die-cast material. The process of the flexible gripper 34 clamping the material occurs when the first… After the hydraulic cylinder 7 drives the moving mold base 9 and the moving mold 10 to move away from the fixed mold 12, the ejector pins of the ejector plate 8 have not yet completely ejected the material. At this time, the flexible gripper 34, driven by a predetermined program, cooperates with the X, Y, and Z axes to clamp the material. Subsequently, the first hydraulic cylinder 7 continues to reset, allowing the ejector plate 8 to completely eject the material with the ejector pins. At this time, the flexible gripper 34 is lifted by the fourth linear motor 31. After lifting the material, the counterweight 27, driven by the first linear motor 26, carries the material to the predetermined external conveyor belt. The fourth linear motor 31 is started to drive the material to descend, releasing the flexible gripper 34. At this time, the stepper motor 3... 3. Depending on the device for placing external materials, the flexible gripper 34 can be rotated to complete the clamping, transportation, and placement of materials; the output plate of the third linear motor 30 is equipped with an L-shaped second limiting rod 35, which facilitates the installation of the limiting placement block 36 and the cleaning table 38 with the external limiting components; a T-shaped placement block 36 is sleeved on the outer side above the second limiting rod 35, and detection grooves are opened on both sides of the top surface of the placement block 36. The placement block 36 facilitates the installation of the limiting camera module 37 with the detection grooves and the external limiting components. The detection grooves are opened on the placement block 36 through an external grooving process.

[0038] Reference Figures 4 to 9As shown, camera modules 37 are vertically installed in both detection tanks. These modules facilitate subsequent inspection of the components within the cleaning station 38 and drying station 40, ensuring the materials are cleaned and dried properly during material removal and cleaning of the moving mold 10 and fixed mold 12. This prevents cleaning fluid residue from remaining in the first and second mold tanks, which could cause color differences and other product inconsistencies in subsequent die-casting materials. The camera modules 37 use custom-designed anti-fog lenses (anti-fog can be achieved using a heated lens principle, with an internal heating wire maintaining the lens temperature above the ambient dew point to prevent fogging), or can be used with external limiting components in conjunction with standard anti-fog lenses. The other end of the second limiting rod 35 is equipped with a cleaning station 38. This station, along with the liquid collection module, temperature sensor 41, and high-pressure atomizing nozzle 42, facilitates cleaning and cooling of the first and second mold tanks after die-casting and material removal. The cleaning station 38, in conjunction with external limiting components, is used to install... The cleaning platform 38 includes a temperature sensor 41, a high-pressure atomizing nozzle 42, and a liquid collection module. A connecting platform 39 is installed below the cleaning platform 38, facilitating connection between the cleaning platform 38 and the drying platform 40 via external limiting components. The drying platform 40 is installed at the other end of the connecting platform 39, allowing for the use of a high-pressure jet nozzle 43 and a liquid collection module to dry the first and second mold troughs cleaned by the cleaning platform 38, preventing residual cleaning liquid in the first and second mold troughs. Multiple temperature sensors 41 are longitudinally and equidistantly installed on both sides of the cleaning platform 38, above and below. These multiple temperature sensors 41 form a temperature control array module, monitoring the temperature of different areas of the corresponding first and second mold troughs in real time, thereby controlling the jet flow rate of the nearby high-pressure atomizing nozzles 42 to prevent excessive material differences due to thermal stress and to prevent mold damage. Multiple high-pressure atomizing nozzles 42 are equidistantly installed between the multiple temperature sensors 41.

[0039] In this invention, a liquid collection module for supplying liquid to the high-pressure atomizing nozzle 42 is installed on one side of the top surface of the cleaning table 38. The high-pressure atomizing nozzle 42 facilitates the spraying of cleaning liquid into the first and second mold slots. The liquid collection module facilitates connection to an external liquid supply device, and the liquid collection module is connected to the corresponding high-pressure atomizing nozzle 42 via a flexible tube. Each corresponding liquid supply tube of the liquid collection module is individually connected to the output unit of an external control system, and its corresponding input unit of the external control system is a temperature sensor 41, thereby achieving the effect of controlling the flow of the high-pressure atomizing nozzle 42. The drying table 40 has drive slots on both sides of the inner cavity, above and below, which facilitate the subsequent positioning of the drive motor. 47, and a flexible tube for limiting and connecting the gas collection module and the high-pressure jet nozzle 43; a connecting groove is provided between the two drive grooves on the same side, through which the high-pressure jet nozzle 43 placed in the lower drive groove can be connected to the gas collection module through the flexible tube; and the drying table 40 is provided with a connecting hole for connecting the drive groove, through which the first connecting block 50 can be fixed; a spherical first connecting block 50 is fixed in each of the multiple connecting holes, through which the first connecting block 50 can be ball-connected to limit the second connecting block 44; a spherical second connecting block 44 is ball-connected inside the first connecting block 50, through which the high-pressure jet nozzle 43 can be limited, and subsequently provides rotation limit for the high-pressure jet nozzle 43.

[0040] In this invention, a high-pressure jet nozzle 43 is installed in the middle of the second connecting block 44. The high-pressure jet nozzle 43 facilitates the drying of the first and second mold slots after cleaning without dead angles, ensuring the dryness of the first and second mold slots, in conjunction with the external hot air and the rotation driven by the connecting rod 46. Fixing blocks 45 are sleeved on the outer sides of the two high-pressure jet nozzles 43 at the same end, facilitating the connection between the connecting rod 46 and the high-pressure jet nozzles 43. A connecting rod 46 is installed between multiple fixing blocks 45 on the same side, facilitating the rotation of the high-pressure jet nozzles 43 relative to the second connecting block 44 relative to the eccentric wheel 48 during the drying process, improving the drying quality. Eccentric wheels 48 are installed at the rear ends of the two connecting rods 46 at the same end. The eccentric wheel 48 facilitates the rotation of the connecting rod 46, which in turn drives the fixed block 45 to rotate at an angle. A drive motor 47 is installed on the adjacent surfaces of the two eccentric wheels 48 at the same end, placed within the drive groove. The drive motor 47 facilitates the rotation of the eccentric wheels 48. Furthermore, the two adjacent surfaces of the two connecting rods 46 at the same end each have a waist hole, and the inner walls of the two drive grooves at the same end are laterally fixed with positioning posts 49 adapted to the sliding limit of the waist hole. The positioning posts 49 facilitate the limiting of the connecting rod 46 during its rotation. Additionally, a gas collection module is installed on one side of the top surface of the drying table 40 to provide gas to the high-pressure jet nozzle 43. The gas collection module facilitates the supply of dry hot air to the high-pressure jet nozzle 43 in conjunction with external gas supply pipes and devices.

[0041] Working principle: In this embodiment, the present invention also proposes a method for using a die-casting device for producing high-strength and tough aluminum pot parts, including the following steps:

[0042] Step 1: Before using the equipment, staff must complete a comprehensive inspection and initialization to ensure stable connections and smooth operation of all components. First, check the tightness of the connections between the hydraulic device 1 and the second hydraulic cylinder 51, third hydraulic cylinder 16, fourth hydraulic cylinder 18, and first hydraulic cylinder 7 to prevent leakage or loosening during hydraulic transmission. Then, verify the circuit connectivity between the control module 2 and the electromagnetic coil 15, first linear motor 26, second linear motor 28, third linear motor 30, fourth linear motor 31, stepper motor 33, drive motor 47, temperature sensor 41, and camera module 37. Simultaneously, test the pressing and rotating sensitivity of the physical buttons (including power-on, emergency stop, and knobs) on the control module 2 to ensure their priority is higher than other components and enables emergency control. Next, check whether the first support platform 5 and the moving mold base 9 move smoothly without jamming under the limiting of the guide rod 3 and the sliding cooperation of the guide rail 4, ensuring smooth mold opening and closing subsequently. After inspection, the equipment is powered on. The liquid collection module and gas collection module are started via the touch screen of the control module 2. The liquid supply and gas supply paths are tested respectively, and the one-way pipe 13, high-pressure atomizing nozzle 42 and high-pressure jet nozzle 43 are checked for blockage. Then, the first hydraulic cylinder 7 is started, pushing the moving mold base 9 to move along the guide rod 3 and the first support platform 5 towards the fixed mold base 11. Because the fixed mold base 11 is limited and fixed by the second support platform 6, it does not slide with the guide rail 4. Finally, the moving mold 10 and the fixed mold 12 are precisely fitted together. The first mold groove and the second mold groove of the two form a complete molding cavity. The ejector plate 8 is fixed under the limit of the guide rod 3, and the ejector pins are stored in the top groove of the moving mold base 9 and the moving mold 10. Finally, the second hydraulic cylinder 51 and the third hydraulic cylinder 16 are started. The third hydraulic cylinder 16 drives the limit platform 17 to rise and fall. The horizontal height of the fourth hydraulic cylinder 18 is finely adjusted so that the impact rod 20 connected to the fourth hydraulic cylinder 18 is precisely aligned with the liquid inlet pipe 14, and the equipment initialization and debugging are completed.

[0043] Step Two: After initialization, the operator sets the die-casting process parameters via the touchscreen of control module 2. Once the parameters are confirmed, the equipment enters the pre-working state. Electromagnetic coil 15 begins preheating, temperature sensor 41 initiates self-testing and feeds back data, and simultaneously, camera module 37, installed in placement block 36, starts capturing images of the initial environment for subsequent calibration. Then, an external robotic arm injects molten aluminum into the inlet pipe 14 through a crucible and the inlet tank. The aluminum accumulates in the inlet pipe 14. At this time, electromagnetic coil 15 is energized to generate an alternating magnetic field, induction heating the aluminum inlet pipe 14 to compensate for temperature loss during the aluminum's transport process, ensuring the aluminum remains in the predetermined liquid state. Next, the fourth liquid casting process is initiated. The pressure cylinder 18, through the coupling block 19, drives the impact rod 20 to move slowly, slowly squeezing the aluminum liquid in the inlet pipe 14 to achieve exhaust and impurity removal and material densification. During this process, the spring 24 in the telescopic platform 22 on one side of the positioning plate 21 in the one-way pipe 13 continuously provides driving force, pushing the T-shaped one-way rod to drive the one-way platform 23 to tightly seal the one-way hole, preventing the aluminum liquid from entering the one-way pipe 13 before densification is completed. After the aluminum liquid temperature stabilizes and densification is completed, the fourth hydraulic cylinder 18 drives the impact rod 20 to move quickly, applying instantaneous pressure to the aluminum liquid. Under the pressure, the aluminum liquid pushes open the one-way platform 23 and squeezes the spring 24, and is injected into the forming cavity formed by the moving mold 10 and the fixed mold 12 through the one-way pipe 13 and the connecting platform, completing the die casting of the aluminum pot accessories.

[0044] Step 3: After the molten aluminum cools and solidifies in the forming cavity, the first hydraulic cylinder 7 initiates the reset procedure, driving the moving mold base 9 and the moving mold 10 to move away from the fixed mold base 11 along the guide rod 3 and guide rail 4, thus separating the moving mold 10 from the fixed mold 12. Since the ejector plate 8 remains fixed under the limit of the guide rod 3, the ejector pins on one side that are adapted to the first mold groove extend along the top groove of the moving mold base 9 and the moving mold 10, pushing the formed aluminum pot parts out of the first mold groove, completing the demolding operation. At the same time as demolding, the equipment starts the material handling process: the first linear motor 26 installed on the support frame 25 drives the counterweight platform 27 to move along the X-axis, and simultaneously starts the second linear motor 28 in the counterweight platform 27, driving the locking platform 29 to move along the Y-axis, thus locking the material. The platform 29 moves to directly above the demolding position; then the fourth linear motor 31 is activated, driving the L-shaped first limit rod 32 to descend along the Z-axis, adjusting the height of the pneumatic flexible gripper 34, and simultaneously activating the stepper motor 33 to adjust the angle of the flexible gripper 34, so that it can accurately grip the ejected aluminum pot parts; after the gripping is stable, the first linear motor 26 and the second linear motor 28 work together to drive the counterweight platform 27 and the locking platform 29 to move, and the fourth linear motor 31 adjusts the height synchronously to transfer the material to the top of the external predetermined conveyor belt; after reaching the position, the fourth linear motor 31 drives the material to descend, the flexible gripper 34 releases, and the stepper motor 33 can adjust the gripper angle according to the placement requirements of the conveyor belt to ensure that the material is placed stably, completing the material picking, placing and transferring;

[0045] Step 4: After the material transfer is completed, the equipment automatically enters the mold cleaning and drying process to ensure the quality of the next round of die casting. First, the first linear motor 26 and the second linear motor 28 work together to move the locking platform 29. At the same time, the third linear motor 30 is started, driving the L-shaped second limit rod 35 to descend along the Z-axis, moving the cleaning platform 38, the connecting platform 39, and the drying platform 40 to the mold cavity area between the moving mold 10 and the fixed mold 12. Then, the camera module 37 collects the mold cavity image again. After confirming that the material has been completely removed and there is no residue, the external liquid supply device is started, and the cleaning liquid is supplied to the high-pressure atomizing nozzle 42 through the liquid collection module. The high-pressure atomizing nozzles 42 distributed on both sides of the cleaning platform 38 spray the cleaning liquid into the inner side of the first mold groove and the second mold groove, cleaning the mold in all directions. During the cleaning process, multiple temperature sensors... The temperature control array module composed of device 41 monitors the temperature of different areas of the mold cavity in real time and feeds the data back to the control system. The control system dynamically adjusts the spray flow rate of the corresponding high-pressure atomizing nozzle 42 according to the temperature data to avoid damage to the mold or incomplete cleaning due to thermal stress caused by temperature difference. After cleaning, the control system starts the external air supply device and supplies dry hot air to the high-pressure air nozzle 43 through the air collection module. At the same time, the drive motor 47 is started to drive the eccentric wheel 48 to rotate. The eccentric wheel 48 drives the connecting rod 46 to swing around the positioning post 49 (limited by the waist hole). The connecting rod 46 drives the high-pressure air nozzle 43 to move through the fixed block 45. Since the high-pressure air nozzle 43 is ball-connected to the first connecting block 50 through the second connecting block 44, the swing of the connecting rod 46 is converted into the angle adjustment of the high-pressure air nozzle 43, realizing the drying of the mold cavity without dead angles.

[0046] Step 5: After the drying process is completed, the camera module 37 will again capture images of the mold cavity to detect the dryness of the mold cavity and determine whether there is any cleaning fluid residue. If the detection result is qualified, it is confirmed that the mold cavity condition meets the die casting requirements. The equipment will automatically reset all components (cleaning table 38, drying table 40 return to their positions, ejector pins are stored, mold is closed, etc.) and immediately enter the next die casting cycle, repeating the process from Step 2 to Step 4. If the detection result is unqualified, it is determined that there is cleaning fluid residue in the mold cavity. The equipment will automatically trigger the re-cleaning process, restart the high-pressure atomizing nozzle 42 and high-pressure air jet nozzle 43, and complete the cleaning and drying according to the standard of Step 4. Only after the camera module 37 detects that the product is qualified can the next cycle be entered, ensuring that the die casting quality of each batch of aluminum pot parts is stable and uniform.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
