[0024] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0025] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0027] An embodiment of this utility model provides a camera base molding die, such as... Figure 1-4 As shown, it includes:

[0028] The front mold assembly 101 includes a front template 102 and a front mold core 103 disposed on the front template 102;

[0029] The rear mold assembly 104 includes a first rear mold 105 disposed below the front mold 102, a rear mold core 108 disposed on the first rear mold 105, a second rear mold 106 disposed below the first rear mold 105, and a third rear mold 107 disposed below the second rear mold 106.

[0030] The internal thread forming assembly 201 includes a rotating rod 202 disposed on the second rear template 106, a thread forming block 203 sleeved on the outside of the rotating rod 202 for forming internal threads, a driving assembly 204 for driving the rotating rod 202 to rotate, and a lifting structure 301 disposed on the first rear template 105. The lifting structure 301 is used to lift the first rear template 105 upward by a predetermined distance, so as to drive the thread forming block 203 to move upward relative to the rotating rod 202, forming a space for the thread forming block 203 to retract its threads downward.

[0031] The first rear template 105 is lifted upwards by a predetermined distance via the lifting structure 301. This predetermined distance is set by those skilled in the art based on the unwinding distance of the internal thread. The first rear template 105 drives the threaded forming block 203, which is connected to the molded part, to move upwards, while the rotating rod 202 remains stationary, creating sufficient downward unwinding space between them. This structure eliminates the need for the rotating rod 202 to move up and down, while still driving the threaded forming block 203 to rotate and unwind during rotation without interference. After unwinding, the threaded forming block 203 automatically slides back to its original position and automatically resets, improving production efficiency and effectively avoiding errors caused by conventional molds after unwinding and resetting. Since the rotating rod 202 only rotates on its own and does not move in either the horizontal or vertical position, the position of the threaded forming block 203 remains unchanged when the mold is closed again, meeting the requirements of high-precision molding. The lifting structure 301 can be a structure such as a spring 303 or a push rod that can lift the first rear template 105. The drive assembly 204 can be a structure that uses a drive chain, drive gear, or other transmission method to rotate the rotating rod 202.

[0032] In some embodiments, such as Figure 1-2 As shown, the rotating rod 202 includes a rotating part 206 connected to the driving assembly 204 and a connecting part 207 for driving the thread forming block 203 to rotate.

[0033] The rotating rod 202 is connected to the drive assembly 204, enabling it to stably receive power and achieve precise rotation control. The design of the connecting part 207 effectively transmits the power of the rotating part 206 to the thread forming block 203. The connecting part 207 can be at least one edge or other shape that can drive the thread forming block 203 to rotate. The thread forming block 203 is sleeved on the connecting part 207. Even if the thread forming block 203 moves up and down, the connecting part 207 can still be driven to rotate, realizing the unthreading and demolding of the internal thread.

[0034] Furthermore, such as Figure 1-2 As shown, the thread forming block 203 includes a sliding groove 208 that is slidably connected to the connecting part 207 and a forming part 209 for forming internal threads; when the mold is closed, the bottom of the thread forming block 203 abuts against the rotating part 206 and the top abuts against the front mold core 103.

[0035] The thread forming block 203 is slidably connected to the connecting part 207 via the sliding groove 208. The first rear template 105 drives the forming part 209, which is connected to the forming part, to move upward, so that a space for unthreading can be formed between the bottom of the thread forming block 203 and the top of the rotating part 206. After unthreading, the thread forming block 203 falls back to the bottom and abuts against the rotating part 206. Then, with the downward pressing of the front mold core 103, the positioning is completed. The structure is simple and the positioning stability is good.

[0036] Furthermore, such as Figure 2 As shown, the rotating part 206 is provided with a pad 210 that abuts against the bottom of the threaded forming block 203.

[0037] The pad 210 provides more stable support for the thread forming block 203. After the thread is unscrewed, the thread forming block 203 will automatically fall onto the pad 210, effectively mitigating the impact of the fall and extending the service life of the mold.

[0038] In some embodiments, such as Figure 2 As shown, the connecting part 207 is a square column.

[0039] The square structure is easy to process and assemble.

[0040] In some embodiments, such as Figure 1 , 3 As shown in Figure 4, the drive assembly 204 includes a power structure 211 disposed on the side of the mold, a main transmission gear set 212 connected to the power structure 211, and a first gear 213 disposed on the second rear template 106 and meshing with the main transmission gear set 212. The first gear 213 is connected to the rotating part 206.

[0041] The main drive gear set 212 transmits the power from the power structure 211 to the first gear 213. The main drive gear set 212 is made up of multiple gears working together to transmit power. The gear transmission has high stability, ensuring the stability of power transmission. It can precisely control the speed and rotation angle of the rotating rod 202, thereby ensuring the forming accuracy of the internal thread.

[0042] Furthermore, such as Figure 1 , 4 As shown, the main drive gear set 212 includes a second gear 214 disposed on the third rear template 107 and a third gear 215 disposed on the second rear template 106 and coaxially rotating with the second gear 214. The third gear 215 meshes with the first gear 213.

[0043] The second gear 214 is set on the third rear template 107, and the third gear 215 is set on the second rear template 106. By distributing the gears on different templates, the vertical space of the mold can be better utilized, interference between gears can be avoided, and the overall compactness of the mold design can be improved.

[0044] In some embodiments, such as Figure 3 As shown, the lifting structure 301 includes a support column 302 disposed on the first rear template 105 and inserted into the second rear template 106, and a spring 303 sleeved on the outside of the support column 302. The bottom of the spring 303 abuts against the second rear template 106, and the first rear template 105 is provided with a first groove for accommodating the spring 303.

[0045] The support column 302 provides effective support for the spring 303 and improves stability. After the mold is opened, the first rear template 105 is lifted by releasing the compressed spring 303. The structure is simple, the cost is low and the space occupied is small.

[0046] In some embodiments, such as Figure 1-2 As shown, the front mold core 103 includes a plurality of front mold core inserts 111 and a molding insert 109 disposed on the front mold core inserts 111, the bottom of the molding insert 109 abutting against the top of the threaded molding block 203; the rear mold core 108 includes a plurality of rear mold core inserts 110 that cooperate with the front mold core inserts 111.

[0047] By disassembling the front mold core 103 into multiple front mold core inserts 111, the processing, maintenance and replacement of the molding cavity are facilitated. If a front mold core insert 111 is damaged, the insert can be replaced individually without replacing the entire front mold core 103, thus reducing the maintenance cost and time of the mold.

[0048] In some embodiments, such as Figure 3 As shown, a camera base molding die also includes an ejector assembly 401 disposed on a second rear template 106 and connected to a first rear template 105. The ejector assembly 401 includes an ejector plate 402 disposed above a drive assembly 204 and ejector pins disposed on the top plate for ejecting the product.

[0049] The ejector plate 402 is mounted on the drive assembly 204, which does not interfere with the drive assembly 204 and improves space utilization.

[0050] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
