Description

Technical Field

[0001] This utility model relates to the field of battery casing mold technology, specifically a battery casing mold. Background Technology

[0002] As a key component of batteries, battery casings made of composite materials are suitable for use in ships or vessels due to their improved overall strength and impact resistance. When manufacturing batteries using composite materials, special battery casing molds are required.

[0003] A search revealed a patent, CN205238602U, which discloses a battery casing molding die, comprising a metal male mold, a first semi-female mold, and a second semi-female mold. The first and second semi-female molds are fixed to the male mold with metal bolts. The male mold has an exhaust port on its back and a sealing groove on its flange. The first and / or the second semi-female mold also have sealing grooves on their flanges, and sealing strips are provided in the sealing grooves. The bottom of the second semi-female mold has an injection port. Using this mold, a battery composite material casing can be integrally molded in one step using a vacuum-assisted RTM process. The resulting composite material casing has advantages such as light weight, high structural strength, and good chemical resistance.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] In reality, after the battery casing is cast, it needs to be removed after the composite material has solidified. However, in the aforementioned comparative document, the solidified battery casing needs to be removed manually, which is quite troublesome and reduces the efficiency of battery casing production. Therefore, there is an urgent need in this field to improve the battery casing mold to overcome the shortcomings of the existing technology. Utility Model Content

[0032] Please see Figures 1-7 A battery casing mold includes a base 5, a male mold 6 fixedly mounted on the upper part of the base 5, and two detachable female molds 1 and 2 on the upper part of the base 5. The first female molds 1 and 2 are adapted to the male mold 6. Adapted first connecting frames 3 and 4 are fixedly mounted on the facing sides of the first female molds 1 and 2, respectively. A telescopic device 7 with a telescopic effect is fixedly mounted inside the male mold 6 on the upper part of the base 5. An ejector rod 8 is fixedly mounted on the telescopic end of the telescopic device 7. An ejector seat 9 fixedly mounted on the upper part of the male mold 6 is engaged with the upper end of the ejector rod 8. Injection ports 10 are provided on the sides of the first female molds 1 and 2. Connecting bottom frames 11 are fixedly connected to the lower sides of the first female molds 1 and 2. Several first fastening bolts 12 with one end threaded to the upper part of the base 5 are passed through the connecting bottom frames 11. Several second fastening bolts 15 for connection are provided between the first connecting frames 3 and 4.

[0033] The specific implementation method in this embodiment is as follows: When it is necessary to use composite materials to produce the battery casing, use a copper spatula to remove the resin curing residue on the sides of the male mold 6, the first female mold 1, and the second female mold 2. Clean the resin curing residue from the injection hole and the discharge hole. Then, use a high-pressure air pipe to remove resin residue, fibers, and dust, and clean the mold. Lay polyester surface felt, glass cloth, and continuous felt on the surface of the male mold 6 according to the process requirements, and trim the seams. After completion, install sealing strips between the first connecting frame 3 and the second connecting frame 4, and between the connecting bottom frame 11 and the base 5. Close the first female mold 1 and the second female mold 2 on the side of the male mold 6, and secure the base with the first fastening bolt 12. The first connecting frame 3 and the second connecting frame 4 are connected by the second fastening bolt 15. Resin is injected into the gap between the male mold 6 and the first female mold 1 and the second female mold 2 through the injection port 10. After the resin has set, the first connecting frame 3 and the second connecting frame 4 are opened and the first female mold 1 and the second female mold 2 are removed. The telescopic device 7 with telescopic effect is activated. The telescopic end of the telescopic device 7 drives the ejector rod 8 to move upward. The ejector rod 8 drives the ejector seat 9 to move upward, pushing the molded battery housing out of the side of the male mold 6. This facilitates the demolding of the molded battery housing and improves the efficiency of battery housing production.
