[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This lithium-boron alloy extrusion molding device features a feeding cylinder at the top of the extrusion cylinder, with a rotating rod containing spiral blades and a fixed rod, driven by a servo motor. This structural design allows the lithium-boron alloy raw material to enter the extrusion cylinder quickly and evenly. The rotation of the spiral blades not only achieves efficient feeding but also provides preliminary mixing of the raw material, preventing agglomeration or blockage during feeding. This improves production efficiency, ensures the stability and uniformity of each feeding, and provides a good raw material foundation for subsequent extrusion molding.
[0015] 2. This lithium-boron alloy extrusion molding device has an electric heating wire wound inside the fixed cylinder on the outer surface of the extrusion cylinder. It is connected to an external power supply through a control switch. According to the characteristics of lithium-boron alloy, the temperature of the raw material inside the extrusion cylinder can be precisely adjusted. The appropriate temperature can reduce the viscosity of lithium-boron alloy, making it more fluid and easier to fill the mold during the extrusion process. This reduces the generation of internal defects, improves the molding quality and pass rate of the product, and ensures that the produced lithium-boron alloy products have good performance and appearance.
[0016] 3. In this lithium-boron alloy extrusion molding device, the mold body is fitted with the insertion slot on the guide block via an insertion block. The structure, utilizing springs, limiting plates, and snap-fit blocks, enables quick installation and stable fixation. When the mold needs to be replaced, simply pressing the snap-fit block allows for easy removal of the mold body. This simple and convenient operation significantly shortens mold replacement time, improves equipment versatility and production flexibility. Simultaneously, the sealing ring in the annular groove on the guide block effectively prevents leakage of the alloy liquid during extrusion, ensuring a clean production environment, avoiding raw material waste and equipment damage caused by alloy liquid leakage, and extending the equipment's service life.

[0025] A cylinder 8 is detachably connected to one side of the extrusion cylinder 1. A piston 9 is detachably connected to the output end of the cylinder 8 through the extrusion cylinder 1. An extrusion block 10 is welded to one side of the piston 9. The extrusion block 10 is in contact with the inner wall of the extrusion cylinder 1. When the cylinder 8 works, it pushes the piston 9 and the extrusion block 10 to move inside the extrusion cylinder 1, thereby moving the lithium boron alloy raw material that has entered the extrusion cylinder 1.
[0026] A fixed cylinder 11 is welded to the outer surface of the extrusion cylinder 1. A spiral electric heating wire 12 is wound around the inner cavity of the fixed cylinder 11.
