Description

Technical Field

[0001] This invention belongs to the field of lithium metal casting mold technology, and particularly relates to a mold that ensures the safe casting of lithium metal. Background Technology

[0002] Lithium metal is a chemically highly reactive light metal that readily oxidizes violently, burns, and even explodes upon contact with air and moisture. Therefore, the casting process requires extremely high levels of sealing, oxidation prevention, contamination prevention, and heat preservation. Casting is the process of melting metal into a liquid that meets predetermined requirements, pouring it into a mold, and then cooling, solidifying, and cleaning to obtain a casting with a predetermined shape, size, and properties. Because the cast blank is nearly complete, minimal or no machining is required, reducing costs and shortening the production cycle, making it a crucial foundational process in modern manufacturing.

[0003] Existing casting equipment (publication number: CN213888135U) controls the quantitative distribution of slurry via an electronically controlled valve and allows for adjustable tilting bucket positions, enabling it to accommodate multiple molds for alternating casting. However, this equipment cannot effectively seal the casting bucket when casting stops, allowing air, moisture, and impurities to enter. Furthermore, it lacks a sealed insulation function, causing the molten lithium to cool and solidify rapidly. Simultaneously, the reactive lithium readily reacts with the introduced air and moisture, posing serious safety hazards such as combustion and explosion. Therefore, this paper proposes a mold to ensure the safe casting of lithium metal, addressing the shortcomings of existing technologies. Summary of the Invention

A casting pouring port 225 is provided at the top of the casting barrel 224. A material hopper 226 is fixedly installed on the inner wall of the middle section of the fixed base plate 1. A guide channel 227 is fixedly installed at the top of the material hopper 226. The molding assembly 23 includes a connecting box 231 fixedly installed at the bottom of the fixed base plate 1. A top mold 232 is provided at the bottom of the connecting box 231. The top mold 232 has casting ports 233 evenly distributed.

[0033] The working principle of the mold for ensuring safe casting of lithium metal is as follows: In actual use, the columns 241 fixedly installed on both sides of the top of the base plate 242 rotate, driving the fixed base plate 1 fixedly installed on the top to move. The top mold 232 connected to the bottom of the connecting box 231 fixedly installed on the bottom of the fixed base plate 1 moves. The bottom mold base 243 fixedly installed in the middle section of the base plate 242 and the top mold 232 close to each other. The connected top mold 232 slides on the inner wall of the bottom mold base 243 to close the mold, which facilitates subsequent casting processing.

[0034] An L-shaped rod 221 is fixedly connected to the inner side of the mounting bracket 211 fixedly installed on both sides of the top of the fixed base plate 1. The drive shaft 222 connected to the bottom of the L-shaped rod 221 drives the ring frame 223 fixedly connected to the inner wall to rotate. The casting barrel 224 fixedly connected to the inner wall of the ring frame 223 rotates accordingly. The top of the material hopper 226 fixedly installed on the inner wall of the fixed base plate 1 is fixedly installed with a guide channel 227, which is connected to the casting pouring port 225 set in the casting barrel 224. The deflected casting barrel 224 pours and casts along the casting pouring port 225. The material falls into the material hopper 226 along the guide channel 227 for collection, avoiding material splashing, preventing the active lithium metal from contacting the external environment, and ensuring construction safety.

[0035] The bottom of the connecting box 231, which is connected to the bottom of the material hopper 226, has casting ports 233 evenly distributed on the outer wall of the top mold 232. The material falls along the casting ports 233 into the inner cavity of the bottom mold base 243 for casting. Vents 246 are evenly distributed on the top of the bottom mold base 243 to facilitate rapid cooling of the internal casting material. The connecting drop bar 244, which is fixedly connected to the bottom of the connecting box 231, slides on the inner wall of the bottom mold base 243. The ejector plate 245, which is fixedly connected to the connecting drop bar 244, slides on the inner wall of the bottom mold base 243 to eject the finished casting material, avoiding inconvenience in handling the material.

[0036] A top cover 2110 is fixedly connected to the top of a support frame 213 fixedly installed on the top of the receiving plate 212. A threaded rod 2111 threaded to the inner wall of the top cover 2110 is fixedly connected to the bottom of a cover plate 2112. A driver 215 fixedly installed on the top of the receiving plate 212 operates, causing an electric push rod 216 fixedly connected to the output end of the driver 215 to extend. A telescopic slide rod 217 hinged to the inner side of the electric push rod 216 moves. The moving telescopic slide rod 217 slides on the outer wall of the arc-shaped rod 218, causing the arc-shaped rod 218 sleeved on the outer wall of the arc-shaped rod 218 to move. The spring 219 is compressed, and the fixed plate 214, which is fixedly connected to the arc-shaped rod 218, rotates. The threaded rod 2111, which is threaded to the inner wall of the fixed plate 214, rotates, causing the cover plate 2112, which is fixedly connected to the bottom of the threaded rod 2111, to descend and cover the connected casting barrel 224, preventing impurities, air, and moisture from entering the casting barrel. The sealed space keeps the molten lithium metal inside the casting barrel warm, preventing the molten lithium metal from cooling and solidifying rapidly. At the same time, it isolates air and moisture, eliminating the safety risks of combustion and explosion of lithium metal.
