Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a mold for producing camera lens rings. Background Technology

[0002] In typical mold structures, for products with complex structures such as internal undercuts, side holes, or lateral shapes, internal undercuts are usually demolded using a slanted ejector mechanism or a conventional internal slide block, while side holes or lateral shapes are demolded using an external slide block with a retracting motion. Each action is often performed independently in separate steps. This requires sufficient demolding space and multiple drive components for individual control, leading to long production cycles, reduced production efficiency, and increased mold complexity. Insufficient control precision can cause scratches, deformation, and even collision damage to mold components, reducing product yield and mold reliability.

[0003] Therefore, the current standard mold operation is as follows: after molding, the male mold separates from the female mold while the outer slider retracts along the outer slider guide block. After the operation is completed, the inner slider of the male mold pulls the core, and finally the product is ejected and demolded. For this product, the standard mold operation is not conducive to smooth core pulling and demolding, and it is easy to cause scratches, sticking to the inner slider, and displacement of the product. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a camera lens ring production mold that effectively avoids problems such as scratches, deformation, and sticking to the mold during the demolding process.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a camera lens ring production mold, including a female mold and a male mold. A female mold core is provided in the female mold, and a male mold core is provided in the male mold. Multiple sets of inner slider assemblies and multiple sets of outer slider assemblies are arranged in a ring inside the male mold. It also includes an outer slider driving mechanism for driving the multiple sets of outer slider assemblies to perform horizontal outward movement. When the male mold and the female mold are closed, the outer slider assemblies, inner slider assemblies, male mold core and female mold core together form the cavity of the camera lens ring. A glue injection port is also provided on the top of the female mold, and the glue injection port is connected to the cavity through a flow channel.

[0006] Furthermore, the inner slider assembly includes an inner slider, and a spring is provided on the outside of the inner slider. One end of the spring is fixedly connected to the male mold core, and the other end of the spring is fixedly connected to the outside of the inner slider.

[0007] The inner side of the multiple sets of inner slider assemblies is provided with an inner slider core puller. The inner slider core puller cooperates with the inclined surface of the multiple sets of inner sliders. When the inner slider core puller moves downward, the inner slider retracts inward under the action of the spring.

[0008] Furthermore, the male mold is also provided with a male mold pre-drawing plate that can move up and down within the male mold, and the male mold pre-drawing plate is fixedly connected to the inner slider core-pulling insert.

[0009] Furthermore, the inner slider core insert has a first groove on its outer side, and the inner slider has a protrusion that engages with the first groove.

[0010] Furthermore, the outer slider driving mechanism includes an ejector plate located inside the mold, a first ejector pin is provided on the ejector plate, and an inclined groove is provided at the bottom of the outer slider. The first ejector pin extends into the inclined groove. When the first ejector pin moves upward, the outer slider moves horizontally outward.

[0011] It also includes a second slide groove disposed within the male mold core, and the outer slider is located within the second slide groove.

[0012] Furthermore, the ejector plate is also provided with a second ejector pin. When the ejector plate moves upward, the outer slider moves horizontally outward, and the product is ejected by the second ejector pin.

[0013] Furthermore, it also includes an external opening and closing device assembly, which includes a lock cylinder, a bolt, and a hook-shaped pin lock. The lock cylinder is fixed on the male mold, one end of the bolt is fixed on the female mold, and the other end of the bolt is inserted into the lock cylinder. One end of the hook-shaped pin lock is fixed on the male mold's first draw plate, and the other end of the hook-shaped pin lock is inserted into the lock cylinder.

[0014] The beneficial effects of this utility model are as follows: The coordinated movement of the inner slider pulling the core first and the outer slider retracting effectively avoids scratches, deformation, and sticking to the mold during demolding, ensuring the integrity of the product's appearance and structure. It improves production efficiency, effectively meeting the high-efficiency requirements of large-scale production. It reduces mold design, processing, and subsequent maintenance costs. It reduces the probability of mold failures caused by mold interference, improves the overall reliability of the mold, and reduces hidden costs in long-term production. Attached Figure Description

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, an embodiment of this application discloses a camera lens ring production mold, including a female mold 1 and a male mold 2. The female mold 1 is provided with a female mold core 3, and the male mold 2 is provided with a male mold core 4. The male mold 2 is provided with a ring of multiple sets of inner slider assemblies and multiple sets of outer slider assemblies. It also includes an outer slider 11 driving mechanism for driving the multiple sets of outer slider assemblies to perform horizontal outward movement. When the male mold 2 and the female mold 1 are closed, the outer slider assemblies, inner slider assemblies, male mold core 4 and female mold core 3 together form the cavity of the camera lens ring. The top of the female mold 1 is also provided with a glue injection port 5, which is connected to the cavity through a flow channel.

[0022] In actual production, male mold 2 and female mold 1 are closed. The outer slider assembly, inner slider assembly, male mold core 4, and female mold core 3 together form the cavity of the camera lens ring. Then, molten plastic is injected into the cavity through the injection port 5 at the top of female mold 1. The plastic fills the entire cavity evenly through the runner. After the plastic cools and solidifies to form the camera lens ring product, the demolding operation begins. First, female mold 1 and male mold 2 separate. Then, the inner slider assembly moves inward, and the outer slider assembly moves outward, allowing the product to be demolded from the inner and outer slider assemblies. Finally, the product can be picked up by an external robotic arm.

[0023] The above structure design, through the coordinated movement of the inner slider 6 retracting inward and the outer slider 11 retracting backward, effectively avoids problems such as scratches, deformation, and sticking to the mold during the demolding process, thus ensuring the integrity of the product's appearance and structure.

[0024] In this embodiment, the inner slider assembly includes an inner slider 6, and a spring 7 is provided on the outside of the inner slider 6. One end of the spring 7 is fixedly connected to the male mold core 4, and the other end of the spring 7 is fixedly connected to the outside of the inner slider 6.

[0025] The inner side of the multiple sets of inner slider assemblies is provided with an inner slider 6 core puller. The inner slider 6 core puller cooperates with the inclined surface of the multiple sets of inner sliders 6. When the inner slider 6 core puller moves downward, the inner slider 6 retracts inward under the action of the spring 7.

[0026] The male mold 2 is also provided with a male mold first-draw plate 9 that can move up and down within the male mold 2. The male mold first-draw plate 9 is fixedly connected to the inner slider 6 core insert.

[0027] Specifically, during the demolding process, when the male mold 2 and female mold 1 begin to separate, the male mold first ejector plate 9 first drives the inner slider 6 core puller to retract downwards. Since the inner slider 6 core puller and multiple sets of inner sliders 6 are in inclined surface contact, the downward retraction of the inner slider 6 core puller causes the inner slider 6 in contact with its inclined surface to contract inwards under the elastic force of the spring 7. At this time, the contact between the inner slider 6 and the inside of the product gradually disengages, creating conditions for the smooth demolding of the product.

[0028] In this embodiment, the inner slider 6 has a first groove 81 on its outer side, and the inner slider 6 has a protrusion 61 that fits into the first groove 81.

[0029] Specifically, during the demolding process, the protrusion 61 on the inner slider 6 slides along the first groove 81 on the outer side of the inner slider 6 core puller. This design not only ensures that the inner slider 6 can retract inward along a predetermined trajectory when the inner slider 6 core puller retracts, but also enhances the stability and precision of the inner slider 6's movement, avoiding product scratches or mold damage caused by movement deviations. Simultaneously, the cooperation between the first groove 81 and the protrusion 61 also serves as a limiting function, preventing the inner slider 6 from excessively retracting under the force of the spring 7, thus ensuring a smooth demolding process.

[0030] In this embodiment, the outer slider 11 driving mechanism includes an ejector plate 10 located in the male mold 2. A first ejector pin 13 is provided on the ejector plate 10. An inclined slide groove 12 is provided at the bottom of the outer slider 11. The first ejector pin 13 extends into the inclined slide groove 12. When the first ejector pin 13 moves upward, the outer slider 11 performs a horizontal outward movement.

[0031] It also includes a second slide groove 41 disposed in the male mold core 4, and the outer slider 11 is located in the second slide groove 41.

[0032] Specifically, after the inner slider 6 retracts inward, the ejector plate 10 begins to move upward under the action of external driving force. The first ejector pin 13 on the ejector plate 10 also moves upward accordingly. Since the first ejector pin 13 extends into the inclined groove 12 at the bottom of the outer slider 11, as the first ejector pin 13 rises, its cooperation with the inclined groove 12 causes the outer slider 11 to make a horizontal outward retraction movement in the second groove 41 within the male mold core 4. This design cleverly utilizes the transmission principle of the inclined plane to convert the vertical movement of the ejector plate 10 into the horizontal movement of the outer slider 11, achieving precise retraction of the outer slider 11. At the same time, the second groove 41 guides and limits the movement of the outer slider 11, ensuring that the outer slider 11 will not deviate or jam during the retraction process, thus guaranteeing the stability and reliability of demolding.

[0033] In this embodiment, a second ejector pin is also provided on the ejector plate 10. When the ejector plate 10 moves upward, the outer slider 11 moves outward horizontally, and the product is ejected by the second ejector pin.

[0034] Specifically, during the upward movement of the ejector plate 10, the second ejector pin on the ejector plate 10 also moves upward synchronously. Since the position of the second ejector pin corresponds to the product, when the second ejector pin rises to a certain height, its tip contacts the bottom of the product and continues to apply upward force, thus smoothly ejecting the product from the already retracted inner slider assembly and the horizontally retracting outer slider assembly. This design makes the product removal action during demolding simpler and more efficient, reduces the risk of product damage that may result from additional robotic gripping steps, and further ensures the product's appearance quality. Simultaneously, the second ejector pin works in conjunction with the first ejector pin 13, completing the retraction of the outer slider 11 and the ejection of the product in a single upward movement of the ejector plate 10, greatly simplifying the demolding process and improving production efficiency.

[0035] In this embodiment, an external opening and closing device assembly 14 is also included. The external opening and closing device assembly 14 includes a lock cylinder, a bolt 15, and a hook-shaped pin lock 16. The lock cylinder is fixed on the male mold 2. One end of the bolt 15 is fixed on the female mold 1, and the other end of the bolt 15 is inserted into the lock cylinder. One end of the hook-shaped pin lock 16 is fixed on the male mold first draw plate 9, and the other end of the hook-shaped pin lock 16 is inserted into the lock cylinder.

[0036] It should be explained that the external opening and closing device assembly 14 is an existing structure and can be purchased directly.

[0037] Specifically, the external opening / closing assembly 14 plays a crucial role in sequence control within this structure. During mold opening, when the female mold 1 and male mold 2 begin to separate, the pin 15 fixed to the female mold 1 is pulled out of the lock cylinder. However, because one end of the hook-shaped lock 16 is fixed to the male mold first-pull plate 9, and the other end is inserted into the lock cylinder, the male mold first-pull plate 9 is temporarily locked due to the cooperation between the hook-shaped lock 16 and the lock cylinder, and cannot immediately retract with the male mold 2. Only when the female mold 1 and male mold 2 have separated to a certain distance, and the pin 15 has completely disengaged from the lock cylinder, can the male mold first-pull plate 9, under the subsequent driving force, drive the inner slider 6 core insert to retract. During mold closing, the male mold first-pull plate 9 needs to first perform a reset movement relative to the male mold 2, allowing the hook-shaped lock 16 to re-insert into the lock cylinder. Only then can the female mold 1 and male mold 2 close smoothly, at which point the pin 15 also re-inserts into the lock cylinder, completing the entire mold closing process. This design ensures that the sequence of movement of each component during the mold opening and closing process is accurate, avoiding problems such as mold collision damage or poor product molding caused by incorrect movement sequence, and further improving the reliability and stability of mold operation.

[0038] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
