[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 7 As shown, this embodiment provides an automatic die-casting machine for lead alloy poles, including a transmission worktable 16. Multiple lead alloy pole molds 17 are evenly spaced around the edge of the transmission worktable 16. The lead alloy pole molds 17 are movably connected to the transmission worktable 16. A copper pole core 1 is placed inside the lead alloy pole mold 17. A pouring mechanism 15, a die-casting mechanism 19, and an ejection mechanism 18 are respectively provided outside the transmission worktable 16. The die-casting mechanism 19 includes a positioning part and a chip removal part of the lead alloy pole mold 17 that are adapted to the lead alloy pole mold 17.

[0029] The operator places the copper core 1 into the lead alloy electrode mold 17, pressing it firmly to the bottom of the mold. After starting the equipment, the transmission table 16 moves the lead alloy electrode mold 17 to the casting station for pouring. Then, the transmission table 16 moves the lead alloy electrode mold 17 to the die-casting station. The positioning part of the lead alloy electrode mold 17 lifts it and suspends it above the worktable. At this time, the hydraulic cylinder above the mold operates to die-cast the lead alloy in the mold, making the lead alloy electrode form a smooth and dense outer surface. After die-casting, the upper hydraulic cylinder rises, and the chip removal part removes the lead chips generated on the upper part of the mold. Then, the transmission table 16 moves the mold to the unloading station, and the ejector mechanism 18 ejects the produced lead alloy electrode from the mold. The operator removes the lead alloy electrode, completing one production cycle. Throughout the production process, the molten lead alloy is kept in a closed machine body under negative pressure ventilation.

[0030] The lead alloy terminal mold 17 is positioned on the transmission worktable 16 and can move upward a short distance, moving with the transmission worktable 16. This multi-station transmission method allows multiple stations to work simultaneously, and one mold can produce multiple products, improving production efficiency. Furthermore, the die-cast lead alloy terminal mold has a smooth outer surface and a dense lead alloy column, reducing casting defects and improving product quality. This invention significantly improves the production efficiency and quality of lead alloy terminals for batteries, and significantly reduces the environmental hazards of lead fumes during the production process.

[0031] Further optimization of the scheme: the lead alloy pole mold 17 includes multiple equally spaced mold positioning holes 3, and a pole copper core positioning block 4 is provided in the mold positioning hole 3. The pole copper core 1 is located in the pole copper core positioning block 4, and the top surface of the lead alloy pole mold 17 is provided with mold positioning holes 3.

[0032] The operator places the copper core 1 onto the copper core positioning block 4 in the lead alloy electrode mold 17 and presses it firmly. Above the copper core 1 is the lead alloy die-cast part 2 of the lead alloy electrode.

[0033] The scheme is further optimized. The casting mechanism 15 includes a first connecting box 20. An aluminum alloy pot is provided on the top surface of the first connecting box 20. A lead spoon 5 is rotatably connected to the side of the first connecting box 20 near the transmission worktable 16. The lead spoon 5 pours liquid lead alloy into the lead alloy pole mold 17. The outlet of the aluminum alloy pot is located above the lead spoon 5.

[0034] In a further optimized design, a first connecting rod 21 is symmetrically fixed to the side of the first connecting box 20 near the lead spoon 5. A first connecting seat 22 is fixed to the top surface of the first connecting rod 21. A first connecting shaft 23 is rotatably connected inside the first connecting seat 22. The first connecting shaft 23 is fixed to the side wall of the lead spoon 5. A second connecting rod 24 is fixed to the outside of one of the first connecting shafts 23. A first hydraulic telescopic rod 25 is hinged to the end of the second connecting rod 24 away from the first connecting shaft 23. The first hydraulic telescopic rod 25 is fixed to the side wall of the first connecting box 20.

[0035] The lead spoon 5 is flipped to pour liquid lead alloy into the lead alloy pole mold 17. After pouring, the lead spoon 5 returns to its original position, and the lead alloy pot 6 replenishes the lead spoon 5 with liquid lead alloy. When the lead spoon 5 needs to be flipped, the first hydraulic telescopic rod 25 is driven to extend, which drives the second connecting rod 24 to rotate around the first connecting shaft 23, thereby causing the lead spoon 5 to flip.

[0036] Further optimization of the scheme: the positioning part of the lead alloy pole mold 17 includes a positioning frame 26, a positioning seat 7 is installed on the positioning frame 26, the top surface of the positioning seat 7 is provided with multiple protrusions, the protrusions are adapted to the bottom of the lead alloy pole mold 17, and the bottom of the positioning seat 7 is provided with a second hydraulic telescopic rod 27, which is fixedly connected to the positioning frame 26.

[0037] To further optimize the design, the top of the positioning frame 26 is provided with an upper pressure plate, which is located above the positioning seat 7. The bottom surface of the upper pressure plate is provided with a positioning pin, which is compatible with the positioning hole 3 of the mold.

[0038] When the transmission worktable 16 transports the lead alloy pole mold 17 to the die-casting mechanism 19, the second hydraulic telescopic rod 27 drives the positioning seat 7 to rise. The positioning seat 7 lifts the lead alloy pole mold 17 from the transmission worktable 16, and then the upper pressure plate presses down to die-cast the liquid lead alloy in the lead alloy pole mold 17 tightly. The lead alloy pole forms a smooth and dense outer surface. After the die-casting is completed, the upper pressure plate rises from the lead alloy pole mold 17, and the chip removal unit works at this time.

[0039] The chip removal unit further optimizes the design by including a chip removal seat 8 fixedly attached to the positioning frame 26. The chip removal seat 8 is hollow inside. A first connecting plate 28 is fixedly attached to one side of the chip removal seat 8. Second connecting plates 29 are symmetrically fixedly attached to both ends of the first connecting plate 28. A driving component 12 is slidably connected between the two second connecting plates 29. The driving component 12 is connected to a chip removal scraper 9.

[0040] In a further optimized design, a scraper positioning plate 11 is fixedly connected to one of the second connecting plates 29, and a tension spring 10 is provided between the chip removal scraper 9 and the drive component 12.

[0041] In the initial position, the chip removal scraper 9 is located on the scraper positioning plate 11. The drive component 12 drives the chip removal scraper 9 to work. The chip removal scraper 9 disengages from the scraper positioning plate 11. Under the pull of the tension spring 10, the chip removal scraper 9 adheres tightly to the upper surface of the lead alloy pole mold 17 to scrape away the lead chips generated by the die-casting product. After the chip removal seat 8 finishes working, the positioning seat 7 descends and disengages from the lead alloy pole mold 17. The lead alloy pole mold 17 returns to the transmission worktable 16. Then, the transmission worktable 16 works to move the lead alloy pole mold 17 to the ejection mechanism 18.

[0042] Further optimization of the scheme: the ejection mechanism 18 includes a connecting frame 30, a third hydraulic telescopic rod 13 is fixedly connected inside the connecting frame 30, and an ejection component is fixedly connected to the top surface of the third hydraulic telescopic rod 13.

[0043] In a further optimized design, the ejector includes a third connecting plate 31 fixed to the top surface of the connecting frame 30. Second connecting shafts 32 are symmetrically fixed to both ends of the top surface of the third connecting plate 31. A fourth connecting plate 33 is fixed to the top surface of the second connecting shafts 32. The fourth connecting plate 33 has multiple connecting holes 34. A fifth connecting plate 35 is slidably connected between the two second connecting shafts 32. The output shaft of the third hydraulic telescopic rod 13 passes through the third connecting plate 31 and is fixed to the bottom surface of the fifth connecting plate 35. Multiple ejector shafts 14 are fixed to the top surface of the fifth connecting plate 35. The ejector shafts 14 are slidably connected to the connecting holes 34 adjacent to them.

[0044] The third hydraulic telescopic rod 13 drives the fifth connecting plate 35 to rise, and the fifth connecting plate 35 drives multiple ejector shafts 14 to rise. The ejector shafts 14 extend from the bottom into the lead alloy pole mold 17, lift the copper core positioning block 4 of the pole, and drive the lead alloy pole to be removed from the lead alloy pole mold 17. The operator removes the lead alloy pole, and the entire production process is completed. The entire lead alloy pole production process is automatically completed by PLC program control.

[0045] Working principle

[0046] At the start of operation, the three lead alloy pole molds 17 are positioned in the positioning device of the transmission worktable 16. The operator places the copper pole core 1 onto the copper pole core positioning block 4 inside the lead alloy pole mold 17 and presses it firmly. After placement, the operator presses the start button, and the transmission worktable 16 moves the lead alloy pole mold 17 to the pouring mechanism 15. The pouring mechanism 15 starts working, and the lead ladle 5 flips to pour liquid lead alloy into the lead alloy pole mold 17. After pouring, the lead ladle 5 returns to its original position, and the lead alloy pot 6 replenishes the lead ladle 5 with liquid lead alloy. Simultaneously, the transmission worktable 16 moves the lead alloy pole mold 17 to the die-casting mechanism 19. At this time, the positioning seat 7 on the die-casting mechanism 19 rises, lifting the lead alloy pole mold 17 from the transmission worktable 16. Then, the upper pressure plate presses down to firmly die-cast the liquid lead alloy in the lead alloy pole mold 17, forming a smooth and dense outer surface for the lead alloy pole. After die-casting is complete, the upper... The pressure plate rises from the lead alloy electrode mold 17. At this time, the chip removal seat 8 works, and the drive component 12 drives the chip removal scraper 9 to work. The chip removal scraper 9 disengages from the scraper positioning plate 11 and, pulled by the tension spring 10, sticks tightly to the upper surface of the lead alloy electrode mold 17 to scrape off the lead chips generated by the die-casting product. After the chip removal seat 8 finishes working, the positioning seat 7 descends and disengages from the lead alloy electrode mold 17. The lead alloy electrode mold 17 returns to the transmission worktable 16. Then, the transmission worktable 16 works to move the lead alloy electrode mold 17 to the ejection mechanism 18. At this time, the ejection mechanism 18 works, and the third hydraulic telescopic rod 13 drives the ejection shaft 14 to rise. The ejection shaft 14 extends from the bottom into the lead alloy electrode mold 17, lifts the electrode copper core positioning block 4, and drives the lead alloy electrode to be removed from the lead alloy electrode mold 17. The operator removes the lead alloy electrode, and the entire production process is completed. The entire lead alloy electrode production process is automatically completed by PLC program control.
