Description

Technical Field

[0001] This utility model relates to the field of negative output protection cover production technology, specifically a negative output protection cover molding mold. Background Technology

[0002] A battery negative terminal protection cover is a protective device that protects and isolates the negative terminal of a battery from its outer casing. It is commonly used in lithium-ion and nickel-metal hydride batteries. It serves multiple functions, including preventing short circuits, preventing the intrusion of external substances, and isolating the electrodes. The role of the negative terminal protection cover becomes even more crucial during battery production, storage, and transportation. Negative terminal protection covers are typically manufactured using injection molding molds.

[0003] Currently, when using injection molding molds to produce negative electrode protection covers, the upper and lower molds of the molding mold need to be combined to form a molding cavity. Raw materials are added into the molding cavity through the sprue, and after cooling, they are removed to form the negative electrode output protection cover. When the upper mold is separated, the negative electrode output protection cover formed inside the lower mold needs to be removed. During this process, the upper mold is idle and cannot perform continuous injection molding operations, resulting in low production efficiency of negative electrode output protection covers. Based on this, a molding mold for negative electrode output protection covers is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a mold for forming a negative output protective cover, so as to solve the problems mentioned in the background art.

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 3 As shown, the negative output protective cover molding die of this embodiment includes a base 1, which is U-shaped. A fixing plate 2 is installed at one end of the base 1, and a fixed upper mold 3 is installed at the lower end of the fixing plate 2. The fixed upper mold 3 is mounted on the fixing plate 2. An injection port 4 is provided on one end surface of the fixed upper mold 3. The injection plastic enters the molding cavity 8 between the fixed upper mold 3 and the movable lower mold 7 through the injection port 4. The injection plastic is shaped into a negative output protective cover according to the shape of the molding cavity 8. A drive motor 5 is installed at the bottom of the base 1. The drive motor 5 is connected to a forward and reverse circuit, which can rotate forward and reverse. The drive motor 5 drives the rotating plate 6 to rotate 180° each time. The rotating plate 6 rotates alternately in forward and reverse directions. The output end of the drive motor 5 is located inside the base 1 and the rotating plate 6 is installed. The upper sides of the rotating plate 6 are symmetrically and movable. There are two movable lower molds 7, each with a cooling mechanism connected to it via pipes. Both the upper end of the movable lower mold 7 and the lower end of the fixed upper mold 3 are provided with molding cavities 8. One movable lower mold 7 is located directly below the fixed upper mold 3. The movable lower mold 7 on the rotating plate 6 is rotated by the drive motor 5, allowing for alternating use of the two movable lower molds 7. This enables continuous injection molding operations and effectively improves production efficiency. A pushing and lifting assembly is installed below the fixed upper mold 3 to push the movable lower mold 7, facilitating the combination of the movable lower mold 7 and the fixed upper mold 3. Alignment assemblies are installed on each movable lower mold 7 to assist in aligning the rising movable lower mold 7 with the fixed upper mold 3, facilitating the combination of the movable lower mold 7 with the molding cavity 8 inside the fixed upper mold 3.

[0021] Specifically, fixed rods 11 are installed on both sides of the lower end of the movable lower mold 7. The lower ends of the fixed rods 11 pass through the rotating plate 6 through through holes. Mounting plates 12 are installed on the lower ends of the fixed rods 11. Spring springs 13 are installed on the upper ends of the mounting plates 12 on the surface of the fixed rods 11. The spring springs 13 pull the fixed rods 11 below the movable lower mold 7 through the mounting plates 12, so that the movable lower mold 7 can return to its original position after rising. When the rotating plate 6 drives the fixed rods 11 to rotate, the fixed rods 11 will not collide with the push cylinder 901.

[0022] Furthermore, the lifting assembly includes a pushing cylinder 901 and a pushing plate 902. The pushing cylinder 901 is installed at the lower end of the base 1 below the fixed upper mold 3, and the pushing plate 902 is installed at the output end of the pushing cylinder 901. The upper end of the rotating plate 6 below the movable lower mold 7 is provided with through slots 14. By extending the pushing cylinder 901, the pushing plate 902 is moved, and the pushing plate 902 moves the movable lower mold 7 upward, thereby realizing the lifting combination of the movable lower mold 7 and the fixed upper mold 3.

[0023] Furthermore, a through slot 14 is located directly above the push plate 902. The size of the through slot 14 is larger than that of the push plate 902. The setting of the through slot 14 will not affect the normal rise of the push plate 902, and the push plate 902 passes through the through slot 14 and contacts the lower end of the movable lower mold 7.

[0024] Furthermore, the alignment assembly includes a connecting plate 1001, a guide post 1002, and an alignment plate 1003. The connecting plate 1001 is installed on the front and rear parts of both ends of the movable lower mold 7, and the guide post 1002 is installed on the connecting plate 1001. The alignment plate 1003 is installed on the front and rear parts of both ends of the fixed upper mold 3. Alignment holes are provided on the alignment plate 1003. When the movable lower mold 7 and the fixed upper mold 3 are combined, the guide post 1002 enters into the alignment hole on the alignment plate 1003 to achieve auxiliary alignment of the movable lower mold 7 and the fixed upper mold 3, which facilitates the combination of the internal forming cavity 8 of the movable lower mold 7 and the fixed upper mold 3.

[0025] Furthermore, the upper end of the guide post 1002 is tapered, and the diameter of the guide post 1002 matches the diameter of the alignment hole. The tapered design of the upper end of the guide post 1002 facilitates the insertion of the guide post 1002 into the alignment hole.

[0026] The usage method of this embodiment is as follows: When the movable lower mold 7 and the fixed upper mold 3 are combined, the cylinder 901 is extended to drive the push plate 902 to move. The push plate 902 passes through the through groove 14 and contacts the lower end of the movable lower mold 7, pushing the movable lower mold 7 to rise. At the same time, the spring spring 13 is compressed. During this process, the guide post 1002 on the movable lower mold 7 enters the alignment hole on the alignment plate 1003 to achieve auxiliary alignment between the movable lower mold 7 and the fixed upper mold 3. The injection plastic enters the molding cavity 8 through the injection port 4. The injection plastic is formed inside the molding cavity 8. When the formed product needs to be removed, the cylinder 901 is shortened, and the spring spring 13 is restored, so that the lower end of the movable lower mold 7 contacts the rotating plate 6. Then, the drive motor 5 drives the rotating plate 6 to rotate 180°, so that the unused movable lower mold 7 is located directly below the fixed upper mold 3, and the movable lower mold 7 with the product is located on one side of the fixed upper mold 3. Then, the above steps are repeated to realize the alternating use of the two movable lower molds 7, which effectively improves production efficiency.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
