Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an injection mold for a new energy vehicle battery connector piece that can quickly switch directions. Background Technology

[0002] In the processing and production of battery connectors for new energy vehicles, metal injection molding plays a crucial role. It is responsible for accurately completing the molding task of the battery connectors. To achieve this process, corresponding injection molds must be provided. In the existing injection molding production process of battery connectors for new energy vehicles, the mold design is clearly divided into positive electrode connector molds and negative electrode connector molds, each dedicated to the injection molding of different types of connectors. Although this division of labor ensures the professionalism and efficiency of production, when faced with a surge in demand for one type of connector and a relatively small demand for the other, it is necessary to flexibly adjust the number of molds used to cope with the changes in production demand. However, most current molds adopt the bolt fixing method. Although this design is stable, it is quite cumbersome and time-consuming when changing molds to match different production needs. Each time the mold is changed, the bolts need to be disassembled and reinstalled, which takes a long time and reduces injection molding efficiency. Summary of the Invention

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Please refer to Figures 1 to 6 :

[0033] Example 1:

[0034] This utility model proposes an injection mold for a new energy vehicle battery connector that can quickly switch directions, comprising: a switching base 1, a switching shaft 2 rotatably mounted on the inner bottom end of the switching base 1; a drive sprocket 3 fixedly mounted on the outer circumference of the switching shaft 2; a main mold body 4 rotatably mounted on the inner top end of the switching base 1; positive electrode grooves and negative electrode grooves respectively opened on the front and rear sides of the main mold body 4; driven sprockets 5 fixedly mounted on the left and right sides of the main mold body 4; driven sprockets 5 connected to the drive sprocket 3 via chains; a switching motor 15 fixedly mounted on the left side of the switching base 1; the output shaft of the switching motor 15 connected to the left end of the switching shaft 2 via splines; mounting grooves 6 opened on the left and right sides of the main mold body 4; a guide plate A7 slidably mounted on the top left and bottom right of the main mold body 4; and a sub-mold A8 fixedly mounted on the front ends of the two guide plates A7.

[0035] This injection mold only requires starting the switching motor 15 to switch between the positive and negative injection states. The switching method is simple and direct. Compared with the traditional method of changing molds, this injection mold directly eliminates the tedious disassembly and assembly steps, saving time on disassembly and assembly, and indirectly improving the injection efficiency of battery connectors.

[0036] In Example 2, based on Example 1, a positive electrode groove matching the front side of the main mold body 4 is provided on the sub-mold A8; a guide plate B9 is slidably installed on the top right side and bottom left side of the main mold body 4; a sub-mold B10 is fixedly installed at the rear ends of the two guide plates B9; a negative electrode groove matching the rear side of the main mold body 4 is provided on the sub-mold B10; an injection port A11 is provided on the top front side of the main mold body 4; the injection port A11 is connected to the positive electrode groove on the front side of the main mold body 4.

[0037] By starting the switching motor 15, it rotates the switching shaft 2, which in turn rotates the driven sprocket 5 and the main mold body 4 under the action of the driving sprocket 3 and the chain. This rotation allows the main mold body 4 to switch the positions of its two faces, the sub-mold A8 and B10, and the injection port A11 and B12, so that any desired injection port can be matched with the injection molding equipment, thus completing the switching of the mold direction.

[0038] In Example 3, based on Example 2, an injection port B12 is provided on the rear bottom side of the main mold body 4; the injection port B12 is connected to the negative electrode groove on the rear side of the main mold body 4; electric push rods A13 are fixedly installed inside the two upper mounting slots 6; the output end of the electric push rod A13 is connected to the sub-mold A8; electric push rods B14 are fixedly installed inside the two lower mounting slots 6; the output end of the electric push rod B14 is connected to the sub-mold B10.

[0039] By opening two different mold grooves for positive and negative electrodes on two sides of a main mold body 4, and cooperating with auxiliary molds A8 and B10 that open corresponding mold grooves for positive and negative electrodes, the two sides of this injection mold have two forming mold grooves for positive and negative electrodes respectively. This allows the injection mold to adapt to the production demand of two types of connecting pieces by switching the direction and putting the appropriate mold groove into use, which improves the flexibility of the injection mold and makes it easy to produce battery connecting pieces of different electrodes according to specific production needs.

[0040] The working principle of this embodiment:

[0041] The injection molding equipment connects the unloading port to the temporarily positioned upper injection port. The molten metal is then injected into the corresponding mold cavity through this injection port, facilitating the injection molding of the battery connector for new energy vehicles. After molding, the corresponding sub-mold is opened by activating the corresponding electric push rod, allowing the molded connector to be removed. During switching, the switching motor 15 is activated, causing it to rotate the switching shaft 2. Under the action of the drive sprocket 3 and chain, the switching shaft 2 rotates the driven sprocket 5 and the main mold body 4. This rotation allows the main mold body 4 to rotate, changing the positions of its two faces, sub-molds A8 and B10, and injection ports A11 and B12, thus matching any desired injection port with the injection molding equipment and completing the mold direction switch.
