Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold for a battery casing that is easy to demold. Background Technology
[0002] An injection mold for battery casings designed for easy demolding is a specialized mold device with optimized demolding structure and function, specifically designed for the injection molding process of battery casings. Its core objective is to solve problems that may occur during the demolding process of traditional battery casing injection molds, such as casing deformation, surface damage, demolding difficulties, and low efficiency. Through targeted design and improvement of key components such as the mold cavity, core, demolding mechanism, and guiding and positioning system, it enables the battery casing to be quickly, smoothly, and completely removed from the mold after molding, while ensuring product dimensional accuracy, surface quality, and production continuity.
[0003] Traditional molds often lack specialized automated demolding structures, making it easy for the molded battery casing to stick to the mold cavity. This requires manual demolding, which not only increases the labor intensity of workers but also easily leads to damage to the battery casing due to improper operation, affecting the product qualification rate. Furthermore, the position and height adjustment of the injection device in traditional molds mostly rely on manual operation, which has low adjustment accuracy and takes a long time. It is difficult to quickly and accurately adjust the injection device to the optimal position matching the mold box, which can easily lead to problems such as material overflow and uneven filling during the injection process, affecting the molding quality of the battery casing. In view of this, we propose an injection mold for battery casings that is easy to demold. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are: This injection mold for a battery casing, designed for easy demolding, involves the following steps during the injection preparation stage: First, a first motor is activated, driving a first threaded rod to rotate. This causes a first threaded block to slide on the base, moving the mounting bracket and adjusting the mounting plate on one side of the bracket and the injection device on the bottom to a suitable position above the mold box, preparing the mold for injection. Next, a second motor is activated, driving a second bevel gear to rotate. Because the second bevel gear meshes with the first bevel gear, the first bevel gear rotates accordingly, driving the second threaded rod to rotate. The second threaded block, threaded onto the outer wall of the second threaded rod, moves along the thread... As the threaded rod moves up and down, the mounting plate, which is fixedly connected to the second threaded block, slides up and down on one side of the fixed frame, thereby precisely adjusting the height of the injection molding device to be close to the mold box for easy injection molding.

A drive assembly is located on one side of the base 1 and is used to move the first threaded block 13. An adjustment assembly is located inside the fixing frame 4 and is used to adjust the height of the mounting plate 5. During the injection preparation stage, the first motor 9 is started, which drives the first threaded rod 12 to rotate. The first threaded block 13 will then slide on the base 1, thereby moving the fixing frame 4. This adjusts the mounting plate 5 on one side of the fixing frame 4 and the injection molding device 6 on the bottom surface to a suitable position above the mold box 3, preparing the position for the injection operation. Then, the second motor 19 is started. The second motor 19 drives the second bevel gear 17 to rotate.

When the battery casing needs to be demolded, the electric push rod 11 in the mold box 3 is activated, and its top pushes the sliding plate 10 upward, pushing the molded battery casing out of the mold box 3, realizing convenient demolding. Throughout the process, the base 1 is kept stable by the two support legs 2 on the bottom surface.

The second threaded block 15 threadedly mounted on the outer wall of the second threaded rod 14 will move up and down along the threaded rod. The mounting plate 5, which is fixedly connected to the second threaded block 15, will slide up and down on one side of the fixed frame 4, thereby precisely adjusting the height of the injection molding device 6 so that it is close to the mold box 3, which facilitates the injection molding operation.

First motor 9 drives first threaded rod 12 to rotate, causing first threaded block 13 to slide on base 1, thereby moving fixing frame 4. This adjusts the mounting plate 5 on one side of fixing frame 4 and the injection device 6 on the bottom surface to a suitable position above mold box 3, preparing the position for injection. Next, second motor 19 is started, driving second bevel gear 17 to rotate. Because second bevel gear 17 meshes with first bevel gear 16, first bevel gear 16 rotates accordingly, driving second threaded rod 14 to rotate. The outer wall of second threaded rod 14 is threaded with… The second threaded block 15 moves up and down along the threaded rod, and the mounting plate 5, which is fixedly connected to the second threaded block 15, slides up and down on one side of the fixing frame 4, thereby precisely adjusting the height of the injection molding device 6 so that it is close to the mold box 3 for easy injection molding.
