Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, specifically relating to a multi-cavity cubic rotary injection mold for producing battery slots. Background Technology

[0002] As a key component of battery modules, the demand for battery cases has increased significantly with the rapid development of the new energy industry.

[0003] Traditional injection molds mostly use single-cavity or simple multi-cavity designs, which result in low production efficiency and difficulty in meeting the needs of high precision and mass production.

[0004] For example, patent application CN109822829A discloses an injection mold for a series of battery slots, including a main mold, a fixing mechanism, and a secondary mold. The side of the main mold is fixedly connected to the side of the secondary mold via the fixing mechanism, and a positioning mechanism is provided inside the main mold. A telescopic mechanism is fixedly installed on the side of the main mold, and the side of the main mold is connected to the top of the base via the telescopic mechanism. This injection mold can only produce one battery slot at a time and cannot automatically and continuously perform injection molding.

[0005] In addition, traditional molds are prone to problems such as uneven filling and product deformation during injection molding, which affect product quality. Utility Model Content

[0006] To address the aforementioned technical problems in the existing technology, this utility model provides a multi-cavity cubic rotary injection mold for producing battery compartments.

[0007] This utility model provides a multi-cavity cubic rotary injection mold for producing battery slots, comprising: a moving mold assembly, wherein the outer surface of the moving mold assembly is provided with at least two sets of moving molds, each set of moving molds including two moving molds arranged opposite each other; a fixed mold assembly, including two movable fixed molds arranged opposite each other, the moving mold assembly being disposed between the two fixed molds; and a rotating mechanism for driving the moving mold assembly to rotate, such that each time only one set of moving molds in the moving mold assembly corresponds to the two fixed molds in the fixed mold assembly and performs injection molding.

[0008] Furthermore, the outer side of the moving mold assembly is provided with two sets of moving molds.

[0009] Furthermore, the four moving molds in the two sets are arranged in a cross shape, and the position of the moving molds can be easily changed through a rotating mechanism.

[0010] Furthermore, the fixed mold is provided with an injection port, the injection surface of the fixed mold is provided with an injection cavity, and the injection surface of the moving mold is provided with an injection block that extends into the injection cavity during injection. After the injection block extends into the injection cavity, it forms a mold cavity for injection molding to form a battery slot.

[0011] Furthermore, each fixed mold has multiple injection cavities, and correspondingly, each moving mold has an injection block that corresponds to each injection cavity.

[0012] Furthermore, the moving mold is provided with a fixed plate, and a movable plate is provided on the outer side of the fixed plate. The injection block is fixed on the fixed plate, and the movable plate has a clearance hole for the injection block to extend outward. The fixed plate is provided with a drive unit to drive the movable plate to move. During the outward movement of the movable plate, the edge of the clearance hole pushes the battery slot off the injection block. The design of the movable plate can reduce manual operation.

[0013] Furthermore, the drive unit includes a cylinder, the fixed plate is also provided with a guide post, and the movable plate is provided with a corresponding guide hole.

[0014] Furthermore, the fixed mold is provided with positioning holes corresponding to the positions of the guide posts, and the guide posts also serve as positioning posts between the moving mold and the fixed mold.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The application of multi-cavity design, rotary design and through-shot injection molding technology enables injection molding and demolding to be carried out simultaneously, which improves the production efficiency of battery compartments and reduces production costs.

[0016] (2) Simultaneous injection of two opposing moving molds and fixed molds can make the injection pressure symmetrical and balanced, ensuring that the molten plastic fills the cavity evenly, resulting in consistent product dimensions and excellent surface quality.

[0017] (3) The rotating mechanism can realize automated operation, reduce manual intervention, and the rotating structure makes the mold structure more compact, reducing the floor space occupied by the production line. Attached Figure Description

Detailed Implementation

[0026] like Figures 1-7 As shown, a multi-cavity cubic rotary injection mold for producing battery slots includes a moving mold assembly 1, a fixed mold assembly 2, and a rotating mechanism 3.

[0027] The outer surface of the moving mold assembly 1 is provided with at least two sets of moving molds 11, each set of moving molds 11 including two moving molds 11 arranged opposite each other. The outer surface of the moving mold assembly 1 can generally be provided with two sets of moving molds 11, such as... Figures 1-2 As shown, four of the two sets of moving modules 11 are arranged in a cross shape.

[0028] The fixed mold assembly 2 includes two movable fixed molds 21 arranged opposite to each other, and the moving mold assembly 1 is located between the two fixed molds 21. The fixed mold 21 is provided with an injection port 22, and the injection surface of the fixed mold 21 is provided with an injection cavity 23. The injection surface of the moving mold 11 is provided with an injection block 12 that extends into the injection cavity 23 during injection. After the injection block 12 extends into the injection cavity 23, it forms a mold cavity for injection molding to form a battery slot.

[0029] Each fixed mold 21 has multiple injection cavities 23, and correspondingly, each moving mold 11 has an injection block 12 that corresponds one-to-one with each injection cavity 23. The number and layout of the injection cavities 23 are determined according to the product size and production requirements, and each injection cavity 23 has an independent cooling channel.

[0030] The moving mold 11 is also provided with a fixed plate 13, and a movable plate 14 is provided on the outer side of the fixed plate 13. The injection block 12 is fixed on the fixed plate 13. The movable plate 14 has a clearance hole 141 for the injection block 12 to extend out. The fixed plate 13 is provided with a drive unit for driving the movable plate 14 to move. The drive unit includes a cylinder. During the outward movement of the movable plate 14, the edge of the clearance hole 141 pushes the battery slot off the injection block 12, which can reduce manual operation.

[0031] The fixed plate 13 is also provided with guide posts 131, and the movable plate 14 is provided with guide holes 142 accordingly. The fixed mold 21 is provided with positioning holes 24 corresponding to the guide posts 131. The guide posts 131 also serve as positioning posts between the movable mold 11 and the fixed mold 21.

[0032] The rotating mechanism 3 drives the moving mold assembly 1 to rotate, so that only one set of moving molds 11 in the moving mold assembly 1 corresponds with the two fixed molds 21 in the fixed mold assembly 2 and performs injection molding at a time. The rotating mechanism 3 can be driven by the servo motor of the injection molding machine's rotating module, and precise rotation angle control can be achieved through a PLC control system.

[0033] Work process: During injection molding, the injection blocks 12 of the two sets of moving molds 11 are extended into the injection cavities 23 of the corresponding fixed molds by the translation of the fixed mold assembly to form a mold cavity for injection molding to form a battery slot. Then, molten plastic is added into the corresponding mold cavity through the two injection ports 22.

[0034] After injection molding is completed, the fixed mold assembly moves away from the moving mold assembly 1, causing the injection block 12 to detach from the injection cavity 23. Then, the rotating mechanism 3 drives the moving mold assembly 1 to rotate 90°, switching the injection surface of the already injected moving mold 11 to the demolding station, and at the same time switching the empty injection surface of the moving mold 11 to the injection station.

[0035] The movable plate 14 on the already injected moving mold 11 moves away from the corresponding fixed plate 13, pushing the battery slot off the injection block 12 to complete demolding. At the same time, the injection surface of the empty moving mold 11 undergoes the above injection process. Through the continuous operation of the rotating mechanism 3, injection and demolding are synchronized, significantly improving production efficiency.
