Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a quick positioning and locking mechanism for a battery protective shell injection mold. Background Technology
[0002] In modern manufacturing, injection molds are key process equipment for molding plastic products. Their positioning accuracy directly affects the dimensional accuracy, assembly performance, and production stability of the products. Traditional injection molds generally use mechanical positioning methods such as guide pillars, guide sleeves, and positioning pins during the positioning process. Such positioning structures rely on the experience calibration and repeated adjustments during manual assembly. Specifically, during the mold closing process, operators need to manually adjust the fit clearance between the guide pillars and guide sleeves, while relying on positioning pins to achieve precise alignment of the upper and lower mold bases.
[0003] However, this traditional positioning method has shortcomings. On the one hand, the manual debugging process is time-consuming and inefficient, making it difficult to meet the needs of large-volume, short-cycle production. On the other hand, due to the influence of human operation factors, the positioning accuracy has large dispersion, which can easily lead to problems such as mold misalignment and eccentricity, resulting in defects such as flash and dimensional deviation in plastic products, thereby increasing the scrap rate and production costs. Therefore, this application provides a quick positioning and locking mechanism for battery protective shell injection molds to meet the requirements. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a quick positioning and locking mechanism for battery protective shell injection molds, so as to solve the problems of low efficiency and unstable positioning accuracy caused by the traditional mechanical positioning method of manual adjustment in injection molds.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A quick positioning and locking mechanism for a battery protective case injection mold includes a positioning seat and a lower mold. A positioning component is installed on the positioning seat, and the positioning component is used to quickly position the lower mold on the positioning seat.
[0007] The positioning component includes a positioning groove, which is formed on the inner wall of the positioning seat. A positioning block is fixedly set at the bottom of the lower mold and slides against the inner wall of the positioning groove. Sliding grooves are formed on both sides of the positioning seat, and a limit rod is slidably set in the sliding groove. A support frame is fixedly set on the outer wall of the positioning seat, and a sliding plate is fixedly set on the outer wall of the limit rod. A spring is fixedly set on the sliding plate, and one end of the spring is fixed to the support frame. Limit holes are formed on both sides of the lower mold, and the limit rod is inserted into the limit hole.
[0008] Preferably, a locking assembly is installed on the positioning seat. The locking assembly is used to fix and lock the lower mold. The locking assembly includes a fixing block, which is fixedly disposed on both sides of the lower mold. The inner wall of the positioning seat is provided with a sliding groove. A sleeve is slidably disposed in the sliding groove. A sliding rod is slidably disposed on the inner wall of the sleeve. A first bolt is rotatably disposed on the inner wall of the sliding rod. A nut is rotatably disposed on the first bolt. A locking block is provided on the inner wall of the sleeve. The nut contacts the locking block. A limiting block is sleeved on the top of the sliding rod. One side of the limiting block contacts the fixing block. The first bolt moves through the limiting block and is threadedly connected to the locking block. The outer wall of the sleeve is fixed to the inner wall of the sliding groove by a second bolt.
[0009] Preferably, an upper mold is slidably disposed on the inner wall of the positioning seat, a plurality of positioning rods are provided on the side of the upper mold near the lower mold, a plurality of positioning holes are provided on the side of the lower mold near the upper mold, and a plurality of round holes are provided on the positioning seat, and the positioning rods pass through the positioning holes and are inserted into the round holes.
[0010] Preferably, the side of the limiting rod closest to the limiting hole is arranged in an arc shape.
[0011] Preferably, a pull ring is provided at the end of the limiting rod away from the limiting hole.
[0012] Preferably, an anti-slip layer is affixed to the side of the limiting block that contacts the fixing block, and the anti-slip layer is in pressure contact with the fixing block.
[0013] Compared with the prior art, this utility model has at least the following beneficial effects:
[0014] In the above scheme, by setting the positioning component, the installation position of the lower mold is quickly determined and the initial positioning is formed by the embedded cooperation of the positioning block and the positioning groove. When the positioning block and the positioning groove are in full contact, the insertion of the limiting rod and the limiting hole completes the further positioning of the lower mold.
[0015] Pulling the pull ring will cause the limit rod to exit the limit hole through mechanical linkage. After unlocking, the lower mold can slide directly out along the positioning groove without additional unlocking steps. Disassembly can be completed with one hand, which significantly improves the efficiency of mold replacement and is especially suitable for high-frequency mold replacement scenarios.
[0016] With the locking component, the sleeve can slide in the groove and be fixed in position by the second bolt, adapting to lower molds of different sizes to meet diverse installation needs;
[0017] First, the horizontal position of the locking component is determined by sliding the sleeve, and then the vertical position is adjusted by sliding the slide rod. The position calibration before installation can be completed in two steps without complicated debugging, achieving quick positioning and locking. Attached Figure Description

[0026] The quick positioning and locking mechanism of a battery protective shell injection mold provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0027] like Figures 1-7 As shown, an embodiment of the present invention provides a quick positioning and locking mechanism for a battery protective case injection mold, including a positioning seat 1 and a lower mold 2. A positioning component 3 is installed on the positioning seat 1, and the positioning component 3 is used to quickly position the lower mold 2 on the positioning seat 1.
[0028] Specifically, the positioning component 3 includes a positioning groove 301, which is formed on the inner wall of the positioning seat 1. The positioning groove 301 matches the positioning block 302 fixedly set at the bottom of the lower mold 2. The positioning block 302 can slide and cooperate with the inner wall of the positioning groove 301, which can play a guiding role, so that the lower mold 2 can quickly and accurately reach the predetermined position along the positioning groove 301 during installation, which greatly shortens the positioning time and improves the mold installation efficiency.
[0029] To further ensure the stability of the lower mold 2 after positioning, sliding grooves 303 are provided on both sides of the positioning seat 1. A limit rod 304 is slidably installed in the sliding groove 303. A sliding plate 306 is fixedly installed on the outer wall of the limit rod 304. A spring 307 is connected to the sliding plate 306. One end of the spring 307 is connected to the support frame 305 fixed on the outer wall of the positioning seat 1. At the same time, limit holes 308 are provided on both sides of the lower mold 2. The limit rod 304 can be inserted into the limit hole 308. When the positioning block 302 slides into the positioning groove 301, the limit rod 304 is pulled to insert into the limit hole 308. At this time, the spring... When the spring 307 is in a stretched state, the elastic tension of the spring 307 tightly fixes the limiting rod 304 in the limiting hole 308, preventing the lower mold 2 from shifting in the horizontal direction, thus achieving the initial positioning and stability of the lower mold 2. In addition, the side of the limiting rod 304 near the limiting hole 308 is arc-shaped. This arc design can guide when inserting into the limiting hole 308, making it easier to insert the limiting rod 304 and further improving the positioning efficiency. The end of the limiting rod 304 away from the limiting hole 308 is provided with a pull ring, which makes it convenient for the operator to pull the limiting rod 304, improving the convenience of operation.
[0030] Furthermore, a locking component 4 is installed on the positioning seat 1. The locking component 4 is used to fix and lock the lower mold 2. The function of the locking component 4 is to fix and lock the lower mold 2 after initial positioning to ensure that the mold will not loosen during the injection molding process.
[0031] Specifically, the locking assembly 4 mainly includes components such as a fixing block 401, a sliding groove 402, a sleeve 403, a sliding rod 404, a first bolt 405, a nut 406, and a limiting block 408. The fixing block 401 is fixedly installed on both sides of the lower mold 2. The inner wall of the positioning seat 1 is provided with a sliding groove 402. The sleeve 403 is slidably installed in the sliding groove 402. The sliding rod 404 is slidably installed on the inner wall of the sleeve 403. The first bolt 405 is rotatably installed on the inner wall of the sliding rod 404. The nut 406 is rotatably installed on the first bolt 405. The inner wall of the sleeve 403 is provided with a locking block 407. The nut 406 can contact the locking block 407. The top of the sliding rod 404 is fitted with a limiting block 408. One side of the limiting block 408 contacts the fixing block 401. During the locking operation, the sleeve 403 is first slid in the sliding groove 402 to a suitable position, and then... The second bolt fixes the sleeve 403 to the inner wall of the slide groove 402, determining the position of the locking assembly 4. Then, the slide rod 404 is pushed to make the limiting block 408 contact the fixing block 401. Next, the first bolt 405 is rotated. Since the first bolt 405 is threadedly connected to the locking block 407, as the first bolt 405 rotates, the nut 406 gradually moves closer to the locking block 407 and squeezes the locking block 407, thereby fixing the slide rod 404 inside the sleeve 403. At the same time, the limiting block 408 tightly squeezes the fixing block 401, achieving a firm lock on the lower mold 2. To enhance the locking effect, an anti-slip layer is pasted on the side of the limiting block 408 that contacts the fixing block 401. When the limiting block 408 and the fixing block 401 are pressed into contact, the anti-slip layer can increase the friction between the two, preventing the lower mold 2 from shifting in the vertical direction, and further improving the reliability of the locking.
[0032] Next, an upper mold 409 is slidably mounted on the inner wall of the positioning base 1. The upper mold 409 is driven by a hydraulic rod to move up and down, completing the mold closing and opening actions with the lower mold 2. Several positioning rods 410 are provided on the side of the upper mold 409 near the lower mold 2, and several positioning holes 411 are provided on the side of the lower mold 2 near the upper mold 409. Several round holes 412 are provided on the positioning base 1. During the mold closing process, the hydraulic rod drives the upper mold 409 to move downward, and the positioning rods 410 pass through the positioning holes 411 and insert into the round holes 412. This cooperation method of multiple positioning rods 410 with positioning holes 411 and round holes 412 further improves the positioning accuracy when the upper mold 409 and the lower mold 2 are closed, ensuring the dimensional accuracy of the battery protective shell injection molding.
[0033] When installing the battery protective case injection mold, first, the positioning block 302 of the lower mold 2 is embedded into the positioning groove 301 on the inner wall of the positioning seat 1 to achieve initial positioning. Then, the lower mold 2 is pushed to slide towards the limiting rod 304 to complete precise positioning. When the lower mold 2 slides along the positioning groove 301 and its outer wall contacts the arc-shaped limiting rod 304, the limiting rod 304 is squeezed and slides along the inner wall of the sliding groove 303, and drives the sliding plate 306 to slide along the inner wall of the support frame 305, thereby compressing the spring 307 until the positioning block 302 of the lower mold 2 is completely embedded in the positioning groove 301. At this time, the outer wall of the lower mold 2 no longer squeezes the limiting rod 304, the spring 307 returns to its deformation, and pushes the sliding plate 306 to drive the limiting rod 304 to insert into the limiting hole 308 of the lower mold 2, thereby achieving rapid positioning of the lower mold 2.
[0034] When it is necessary to release the positioning of the lower mold 2, the operator only needs to pull the pull ring, which will cause the limit rod 304 to slide along the sliding groove 303 and compress the spring 307, so that the limit rod 304 will exit from the limit hole 308, releasing the locking state of the lower mold 2. At this time, the positioning constraint of the lower mold 2 is only the cooperation between the positioning block 302 and the positioning groove 301. The operator can easily slide the lower mold 2 out along the positioning groove 301, completing the quick disassembly process of the mold. The locking and unlocking of the mold can be achieved through simple linear operation, which improves the mold replacement efficiency.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
