[0025] Example 1, please refer to Figures 1-8 This embodiment provides a die-casting equipment for aluminum alloy housing die-casting parts, including: a base 1; a support plate 2, the support plate 2 being fixedly connected to the upper end of the base 1; a top plate 3, the top plate 3 being fixedly connected to the top of the support plate 2; a cylinder 4, the cylinder 4 being fixedly connected to the upper end of the top plate 3; an aluminum alloy die-casting device 5, the aluminum alloy die-casting device 5 being fixedly connected to the output end of the cylinder 4; and a die-casting mold 6, the die-casting mold 6 being fixedly connected to the upper end of the base 1. A U-shaped plate 71 is fixedly connected to the outer wall of the support plate 2. Slide grooves 72 are provided on both sides of the U-shaped plate 71. A moving rod 73 is slidably connected inside the slide grooves 72. A connecting rod 74 is rotatably sleeved on the outer wall of one end of the moving rod 73. The other end of the connecting rod 74 is rotatably connected to a connecting plate 75 via a pin. The other end of the connecting plate 75 is fixedly connected to the outer wall of the aluminum alloy die-casting equipment 5. An mounting plate 76 is fixedly sleeved on the outer wall of the moving rod 73. A fixing rod 77 is fixedly connected to the inner wall of the U-shaped plate 71. A transmission cylinder 78 is movably sleeved on the outer wall of the fixing rod 77. One end of the transmission cylinder 78... The end of the transmission cylinder 78 is rotatably connected to the outer wall of the mounting plate 76, and a bevel gear A79 is fixedly sleeved on this end. The outer wall of the mounting plate 76 is rotatably connected to the mounting shaft 710 and the spray pipe 712. The outer wall of the mounting shaft 710 is fixedly sleeved with a bevel gear B711 and a turntable 715. The outer wall of the fixing rod 77 is provided with a spiral groove 714. The inner wall of the transmission cylinder 78 is fixedly connected with a sliding shaft 713. The outer wall of the spray pipe 712 is fixedly connected with a rectangular frame A719. The outer wall of the turntable 715 is fixedly connected with a fixing shaft 716. Multiple nozzles are provided at the bottom of the spray pipe 712.

[0026] The sliding shaft 713 is slidably connected inside the spiral groove 714, the fixed shaft 716 is slidably connected to the inner wall of the rectangular frame A719, and the bevel gear A79 meshes with the bevel gear B711. The two achieve transmission cooperation through meshing, thereby completing the corresponding mechanical action.

[0027] The side of the support plate 2 has a movable groove 717, and one end of the connecting plate 75 passes through the movable groove 717 and is slidably connected to it. This structural design makes the cooperation between the two more flexible and stable, and also provides convenience and adjustable space for subsequent use.

[0028] A liquid storage tank 718 is fixedly connected to the upper end of the spray pipe 712. The liquid outlet at the bottom of the liquid storage tank 718 is connected to the spray pipe 712, thereby ensuring that the liquid in the liquid storage tank 718 can flow smoothly into the spray pipe 712 to complete the liquid transportation process.

[0029] When in use, the operator first moves cylinder 4 to lower the aluminum alloy die-casting equipment 5. When the aluminum alloy die-casting equipment 5 lowers, it will lower the connecting plate 75. Then the connecting plate 75 will move the hinged connecting rod 74 downward. The moving rod 73 at the other end of the connecting rod 74 will be pushed to the side inside the slide groove 72. Then the moving rod 73 will lower the mounting plate 76. The mounting plate 76 will move the spray pipe 712 until it leaves the upper end of the die-casting mold 6. At this time, the operator can control the robotic arm to hold the crucible and pour the molten aluminum alloy into the interior of the die-casting mold 6. After the molten aluminum alloy is poured in, the aluminum alloy die-casting equipment 5 continues to lower, using high pressure to inject the liquid aluminum alloy into the precision mold cavity at high speed, so that the aluminum alloy cools and solidifies rapidly under pressure. Then, the cylinder 4 can drive the aluminum alloy die-casting equipment 5 to rise. During the process of the aluminum alloy die-casting equipment 5 rising, the connecting plate 75 moves upward accordingly. The connecting rod 74 pulls the moving rod 73 to slide along the slide groove 72 towards the die-casting mold 6. The mounting plate 76 moves synchronously and drives the transmission cylinder 78 to slide on the fixed rod 77. Since the sliding shaft 713 is slidably connected to the spiral groove 714, the transmission cylinder 78 will rotate due to the guiding effect of the spiral groove 714 when it slides. This will drive the bevel gear A79 on its outer wall to rotate. Since the bevel gear A79 meshes with the bevel gear B711, the bevel gear B711 will also rotate, which will drive the mounting shaft 710 to rotate. The mounting shaft 710 drives the turntable 715 to rotate. The fixed shaft 716 on the turntable 715 slides in the rectangular frame A719. When the fixed shaft 716 rotates with the turntable 715, it will drive the rectangular frame A719 to swing, thereby pushing the spray pipe 712 to swing left and right. Simultaneously, when the spray pipe 712 moves to the upper end of the die-casting mold 6, it opens the solenoid valve connecting to the liquid storage tank 718. The release agent in the liquid storage tank 718 is then evenly sprayed onto the cavity surface of the die-casting mold 6 through multiple nozzles at the bottom of the spray pipe 712. As the spray pipe 712 swings left and right, the nozzles fully cover the mold cavity, ensuring uniform adhesion of the release agent and effectively preventing the aluminum alloy die-casting parts from sticking to the mold, thus providing favorable conditions for subsequent demolding processes. Meanwhile, the sliding process of the moving rod 73 is stable. Through the cooperation of the connecting rod 74 and the connecting plate 75, it achieves linkage with the lifting action of the aluminum alloy die-casting equipment 5, eliminating the need for an additional drive device, simplifying the equipment structure, and reducing energy consumption.

[0030] Example 2, please refer to Figures 1-8Based on Embodiment 1, a cleaning assembly 8 is assembled on the upper end of the base 1. The cleaning assembly 8 includes an L-shaped plate 81, which is fixedly connected to the upper end of the base 1. A reciprocating screw 82 and a gear ring 84 are rotatably connected to the inner and outer sides of the L-shaped plate 81, respectively. One end of the reciprocating screw 82 passes through the L-shaped plate 81 and is fixedly connected to a ratchet 83. A pawl 85 is hinged to the inner wall of the gear ring 84. A gear plate A87 is fixedly connected to one end of the moving rod 73. An installation block 88 is threadedly connected to the outer wall of the reciprocating screw 82. Two rotating shafts 89 are rotatably connected to the outer wall of the installation block 88. One end of the two rotating shafts 89 rotatably passes through the installation block 88 and is fixedly connected to a large gear 811 and a small gear 812, respectively. A brush cylinder 810 is fixedly connected to the other end of the two rotating shafts 89. A gear plate B813 is fixedly connected to the inner side of the L-shaped plate 81. Slag troughs 814 are opened on both sides of the base 1.

[0031] The gear ring 84 meshes with the gear plate A87, the large gear 811 meshes with the gear plate B813, and the small gear 812 meshes with the large gear 811. A spring A86 is fixedly connected to the inner wall of the gear ring 84, and the other end of the spring A86 is fixedly connected to the pawl 85.

[0032] During use, a small amount of molten aluminum alloy will drip onto the front side of the top of the base body 1 while the moving rod 73 is moving. The toothed plate A87 engages with the toothed ring 84, causing the toothed plate A87 to rotate. However, when the moving rod 73 moves away from the top of the mold, this is the time when the aluminum alloy is being poured in. Since the dripped aluminum alloy has not yet cooled, it cannot be cleaned. Therefore, the toothed plate A87 will cause the toothed ring 84 to rotate clockwise. At this time, the toothed ring 84 will not drive the ratchet 83 to rotate via its internally hinged pawl 85. When the moving rod 73 moves closer to the mold, the toothed plate A87 drives the toothed ring 84 to rotate counterclockwise. At this time, the pawl 85 engages with the ratchet 83 under the elastic force of the spring A86, thereby driving the ratchet 83 to rotate synchronously, which in turn causes the reciprocating screw 82 to rotate. When the reciprocating screw 82 rotates, the mounting block 88 on its outer wall will reciprocate along the screw direction. During the movement of the mounting block 88, the large gear 811 meshes with the toothed plate B813 fixed inside the L-shaped plate 81, thereby driving the large gear 811 to rotate. The large gear 811 then meshes with the small gear 812, causing the small gear 812 to rotate as well. In turn, the two rotating shafts 89 drive the brush cylinder 810 to rotate. This allows the two brush cylinders 810 to rotate in opposite directions and at different speeds, creating a combined effect of tearing, grinding, and sweeping the solidified material. The cleaning efficiency is far superior to unidirectional scraping. The brush cylinders 810 use a mixture of high-temperature resistant steel and copper wire bristles, providing a certain rigidity while preventing scratches on the cast iron surface. This effectively cleans the cooled aluminum alloy residue dripping from the upper end of the base 1, pushing the residue into the slag droppers 814 on both sides of the base 1, preventing residue accumulation from affecting subsequent die-casting operations. This linkage cleaning structure uses the movement of the moving rod 73 as a power source, eliminating the need for additional drive components and further improving the equipment's integration and energy efficiency.

[0033] Example 3, please refer to Figures 1-8 Based on embodiment 1, a recycling component 9 is assembled on the upper end of the base 1. The recycling component 9 includes a through groove 91, which is opened on the upper end of the base 1. A baffle 92 is hinged to the inner wall of the through groove 91 by a pin. A connecting shaft 93 is rotatably connected to the outer wall of the other side of the baffle 92. A connecting block 94 is fixedly connected to the other end of the connecting shaft 93. A movable shaft 95 is rotatably connected to the outer wall of the connecting block 94. A rectangular frame B96 is slidably connected to the outer wall of the movable shaft 95. A linkage block 97 is fixedly connected to the outer wall of the rectangular frame B96. A push plate 99 is fixedly connected to the bottom of the mounting plate 76. A receiving groove 910 is opened on the inner wall of the through groove 91.

[0034] An elastic telescopic rod 98 is fixedly connected to the upper end of the base 1. The top of the elastic telescopic rod 98 is fixedly connected to the bottom of the linkage block 97. This connection method is very stable, ensuring that there will be no relative movement or loosening between the linkage block 97 and the elastic telescopic rod 98, thereby ensuring the stability and reliability of the entire structure during operation.

[0035] The front part of the push plate 99 near the baffle 92 is set as an inclined surface, and the rear part of the push plate 99 is set as a flat surface. This structure can effectively reduce the friction when in contact with the baffle 92 and help guide the smooth movement of materials or parts. The rear part of the push plate 99 adopts a flat surface design, which can provide a larger contact area, thereby enhancing the stability and support of the push plate 99 during operation and ensuring that it can better perform its intended function.

[0036] When using the machine, the release agent sprayed from the nozzle will drip and splash around the machine, which is not only wasteful but also causes serious environmental pollution and makes the working area slippery. Therefore, a recycling bin can be placed at the lower end of the through-slot 91 for recycling. Since the through-slot 91 needs to prevent molten aluminum alloy from entering, it cannot be kept open all the time. When the spray pipe 712 and other components are away from the mold, the elastic telescopic rod 98 will pull the rectangular frame B96 to a lower position, and the movable shaft 95, which is slidably connected to its inner wall, will also descend. Then, the connecting block 94 at one end of the movable shaft 95 will drive the baffle 92 to rotate into the through-slot 91 through the connecting shaft 93, closing it. When spraying is required, the mounting plate 76 moves to drive the... The push plate 99 moves synchronously. The inclined surface at the front of the push plate 99 first contacts the baffle 92 and gradually pushes the baffle 92 to flip upward. During the flipping process, the connecting block 94 moves through the connecting shaft 93. The connecting block 94 then pushes the movable shaft 95 to slide within the rectangular frame B96. At the same time, the linkage block 97 moves upward under the action of the elastic telescopic rod 98 until the baffle 92 fully opens the through groove 91. At this time, the release agent can fall into the recycling box below through the through groove 91, realizing the recycling of the release agent and reducing production costs. After the spraying is completed, the mounting plate 76 drives the push plate 99 to move in the opposite direction. The plane at the rear of the push plate 99 gradually disengages from the baffle 92. The elastic telescopic rod 98 pulls the linkage block 97 downward, and the rectangular frame B96 descends accordingly. The movable shaft 95 slides within the rectangular frame B96 and drives the baffle 92 to flip downward through the connecting block 94 and the connecting shaft 93 until the baffle 92 closes the through groove 91 again, preventing impurities such as molten aluminum alloy from entering the through groove 91 and causing blockage.

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.
