Description

Technical Field

[0001] The utility model relates to the technical field of battery shell processing, in particular to a lithium battery shell forming device. Background Art

[0002] As we all know, lithium batteries are widely used in large-scale equipment such as electric vehicles and electric motorcycles. Lithium batteries are a type of battery that refers to batteries with lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution.

[0003] The Chinese patent with the existing patent announcement number "CN213704271U" discloses "a shell forming device for lithium battery production". The lower template fixed on the upper surface of the support plate is pushed to the lower part of the load-bearing plate by an electric push rod, and forms a closed state with the upper template. The bottom of the upper template will slide and fit with the positioning groove on the upper surface of the support plate. After the shell is formed, the electric push rod is controlled to descend and the shell can be removed from the lower template. The operation is simple and the shell is easy to remove from the lower template. The heating plate installed inside the shell installed on the upper surface of the load-bearing plate can melt the plastic raw material in the feeding pipe, and the melted raw material liquid is transported from the feeding pipe to the top of the upper template. When the upper and lower templates are closed, the raw material liquid will fill the gap between the upper and lower templates. After the raw material is cooled and formed, the electric push rod is lowered, and the formed shell can be removed from the lower template. The overall structure is simple, the weight is reduced, it is easy to move and install, the equipment cost is low, and the cost pressure of the enterprise can also be reduced.

[0004] However, the above patent cannot refrigerate the raw materials, and the raw materials between the upper template and the lower template can only be cooled naturally during cooling, resulting in a long cooling and molding time and low cooling and molding efficiency. Therefore, we propose a lithium battery shell molding device to solve the above-mentioned problems. Utility Model Content
