Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a forming mold for a hinge component of a foldable screen mobile phone. Background Technology

[0002] Foldable screen phones have become popular products in the current smartphone field due to their advantages of being foldable and highly portable. As the core component for enabling the opening and closing function of foldable screen phones, the processing precision of the hinge directly affects the folding feel and lifespan of the phone. During the production process of the hinge, it is necessary to perform precision processing through forming molds to ensure the dimensional accuracy and assembly compatibility of the hinge. In existing foldable screen phone hinge forming molds, the lower mold, as the core forming component, is prone to wear and deformation of its internal positioning pins when subjected to the stamping pressure of forming processes over a long period. This leads to a decrease in the positioning accuracy of the lower mold, which in turn affects the processing quality of the hinge component. Therefore, when the positioning pins wear out, the lower mold needs to be disassembled and replaced or repaired in a timely manner. However, currently, the forming molds in the industry mostly use multiple bolts to fasten the lower mold to the support base. This fixing structure has obvious defects: on the one hand, the bolts need to be aligned with the threaded holes and tightened one by one during installation, which is cumbersome and the positioning accuracy depends on manual installation experience; on the other hand, when it is necessary to disassemble the lower mold, tools are needed to loosen the bolts one by one, which is not only inefficient, but repeated disassembly can also cause the threaded holes to strip, affecting the reusability accuracy of the mold, increasing the maintenance cost and downtime of the mold, and seriously restricting the mass production efficiency of the hinge component. Utility Model Content

[0003] The purpose of this utility model is to provide a forming mold for the hinge component of a foldable screen mobile phone to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a shaping mold for a folding screen mobile phone hinge component, comprising a support base and a lower mold. The lower mold is provided at the top of the support base, and limit sliders are fixed on both sides of the bottom end of the lower mold. A first inclined block is fixedly connected to the inner side of the limit slider. Auxiliary components are provided on both sides of the top of the support base. A cavity is opened inside the support base, and a double-ended stud is rotatably connected to the center of the cavity through a bearing seat. Threaded blocks are threadedly connected to both sides of the outer wall of the double-ended stud. A limit block is fixed at the bottom end of the threaded block. A groove block is fixedly connected to the front end of the double-ended stud, and the groove block is exposed on the front surface of the support base and has a diamond-shaped groove inside. A transmission component is provided on the outer side of the threaded block.

[0005] Preferably, the support base has slots on both sides that match the limiting slider and the first inclined block.

[0006] Preferably, the auxiliary component includes a pointer, which is detachably disposed on the left side of the lower mold. A scale plate is disposed at the position corresponding to the pointer, and the bottom end of the scale plate is connected to the support base.

[0007] Preferably, the transmission assembly includes a transmission rod rotatably connected to the outside of the threaded block, and a second inclined block is rotatably connected to the outside of the transmission rod.

[0008] Preferably, the inclined side of the second inclined block corresponds to the inclined side of the first inclined block, and is used to provide a downward pressing force on the first inclined block when the second inclined block moves outward.

[0009] Preferably, a limiting groove is formed at the center of the cavity of the support base corresponding to the position of the threaded block, so as to provide the limiting block with a space for movement.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This mold achieves visual calibration of the lower mold installation position by setting auxiliary components (pointer and scale plate). Operators can quickly determine whether the lower mold is in the initial installation reference position by observing the alignment of the pointer with the scale line on the scale plate, avoiding the forming error of the rotating shaft due to installation offset. At the same time, the cooperation between the limit slider and the support seat slot forms a dual positioning structure, ensuring the accuracy of the lower mold installation position from both mechanical limit and visual indication aspects, providing a stable reference for the forming of the rotating shaft, and effectively improving the forming accuracy and consistency of the product.

[0011] By using the inclined edge design of the first and second inclined blocks, the horizontal thrust transmitted by the transmission component is converted into a vertically downward clamping force. The force direction conversion is efficient and has low loss. The double-ended stud adopts a reverse thread design, which can drive the threaded blocks on both sides to move synchronously relative to each other or in opposite directions. This ensures that the force exerted by the second inclined blocks on the first inclined block is symmetrical and uniform, avoiding loosening or deformation of the lower mold due to force imbalance. In addition, the cooperation of the limiting block and the limiting groove restricts the movement range of the threaded block while ensuring its horizontal movement stability, further improving the consistency of force transmission and making the lower mold firmly pressed on the support base.

[0012] This mold, through the combination of a groove block and a special diamond-shaped wrench, provides a convenient operating interface for rotating the double-ended stud. Operators only need to rotate the wrench in the forward and reverse directions to complete the installation, fixing, disassembly, and replacement of the lower mold. The operation process is simple and easy to understand, requiring no complicated professional skills. Moreover, the entire transmission process automatically realizes the conversion and synchronous transmission of force through a mechanical structure, without the need for additional auxiliary equipment, which greatly improves the ease of use and operating efficiency of the mold, and reduces labor and time costs.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution for a foldable screen phone hinge forming mold: a foldable screen phone hinge forming mold includes a support base 1 and a lower mold 2. The lower mold 2 is set at the top of the support base 1. The support base 1 serves as the basic load-bearing component of the entire mold, providing a stable installation reference for the lower mold 2, auxiliary components, transmission components, etc. Limiting sliders 3 are fixed on both sides of the bottom end of the lower mold 2. The limiting sliders 3 connect the lower mold 2 and the middle component of the first inclined block 4 to realize the transmission of force. The first inclined block 4 is fixedly connected to the inner side of the limiting slider 3. The first inclined block 4 is a transmission force-bearing component. Through the contact of the inclined side with the inclined side of the second inclined block 12, the horizontal thrust of the second inclined block 12 is converted into the vertical downward pressure of the limiting slider 3. Auxiliary components are provided on both sides of the top of the support base 1. The support base 1 has an internal cavity, and a double-ended stud 7 is rotatably connected to the center of the cavity via a bearing seat. The double-ended stud 7 is the core transmission component. By rotating, it drives the threaded blocks 8 on both sides to move horizontally in opposite directions. The reverse thread design ensures that the movement direction of the threaded blocks 8 on both sides is consistent, providing synchronous power to the transmission component. Threaded blocks 8 are threadedly connected to the outer walls of the double-ended stud 7. The threaded blocks 8 are intermediate components that transmit power. Through the engagement of the threads with the double-ended stud 7, they convert the rotational motion of the double-ended stud 7 into its own horizontal linear motion. The bottom end of the threaded block 8 is fixed with a limit block 9, which limits the range of motion of the threaded block 8. The cooperation with the limit groove can help the threaded block 8 maintain horizontal movement. The front end of the double-ended stud 7 is fixedly connected with a groove block 10, and the groove block 10 is exposed on the front surface of the support base 1. The groove block 10 has a diamond-shaped groove inside. The groove block 10 provides a rotation operation interface for the double-ended stud 7. The operator can insert a special diamond-shaped wrench into the groove and rotate the groove block 10 to drive the double-ended stud 7 to rotate. A transmission component is provided on the outside of the threaded block 8. The two sides of the support base 1 have slots that match the limit slider 3 and the first inclined block 4.

[0017] The auxiliary components include a pointer 5, which is detachably mounted on the left side of the lower mold 2. The pointer 5 is used to indicate the positional changes of the lower mold 2, and its tip precisely points to the scale line of the scale plate 6, making it convenient for operators to visually observe whether the lower mold 2 has moved into place during installation. The scale plate 6 is located at the position corresponding to the pointer 5, and the bottom end of the scale plate 6 is connected to the support base 1. The scale plate 6 and the pointer 5 work together to provide a precise measurement reference for the position of the lower mold 2; the clear scale line makes it easy for operators to read the movement distance of the lower mold 2.

[0018] The transmission assembly includes a transmission rod 11, which is rotatably connected to the outside of the threaded block 8. The transmission rod 11 is a transmission component connecting the threaded block 8 and the second inclined block 12, converting the horizontal movement of the threaded block 8 into the horizontal movement of the second inclined block 12. The second inclined block 12 is rotatably connected to the outside of the transmission rod 11. The second inclined block 12 cooperates with the first inclined block 4 to realize the conversion of the force direction. When it moves outward under the drive of the transmission rod 11, it contacts the inclined edge of the first inclined block 4 through the inclined edge, generating a vertical downward pressure that is transmitted to the first inclined block 4 and the limiting slider 3. The inclined edge of the second inclined block 12 corresponds to the inclined edge of the first inclined block 4, and is used to provide a downward pressing force on the first inclined block 4 when the second inclined block 12 moves outward. A limiting groove is opened at the center of the cavity of the support base 1, corresponding to the position of the threaded block 8, to provide movement space for the limiting block 9.

[0019] Working Principle: When a foldable screen phone hinge forming mold is first used, the operator places the lower mold 2 at the top of the support base 1. The limiting sliders 3 on both sides of the bottom of the lower mold 2 align with the slots on both sides of the support base 1, completing the initial position calibration. At this time, the pointer 5 on the left side of the lower mold 2 points to the corresponding scale plate 6 on the support base. The operator judges whether the lower mold is in the initial installation reference position by observing the alignment of the pointer 5 with the scale line 6. Then, the operator uses a special diamond-shaped wrench to insert into the exposed groove block 10 on the front surface of the support base. Rotating the groove block 10 drives the double-ended stud 7 at the center of the cavity of the support base 1 to rotate. Through the threaded engagement, this is converted into the synchronous horizontal relative movement of the threaded blocks 8 on both sides. During this process, the limiting block 9 at the bottom of the threaded block 8 moves along... The sliding of the limiting groove opened in the cavity of the support base 1 not only restricts the movement range of the threaded block 8, but also ensures the stability of the horizontal movement of the threaded block 8. When the threaded block 8 moves horizontally, the transmission rod 11 rotatably connected to its outer side pushes the second inclined block 12 to move outward (towards the first inclined block). The inclined side of the second inclined block 12 corresponds to the inclined side of the first inclined block 4 fixed inside the limiting slider 3 of the lower mold 2. As the second inclined block 12 continues to move outward, the inclined sides of the two inclined blocks come into contact with each other and generate compression. Through the cooperation of the inclined sides, the horizontal thrust of the second inclined block 12 is converted into a vertical downward pressure. This pressure is transmitted to the limiting slider 3 through the first inclined block 4, and then acts on the lower mold 2. Under the action of vertical pressure, it is firmly pressed against the top of the support base 1, completing the installation and fixing. The operator uses a special diamond-shaped wrench to rotate the slot block 10 in the opposite direction, which drives the double-ended stud 7 to rotate in the opposite direction. Due to the reverse thread design, the threads 8 on both sides move in opposite directions in the horizontal direction. The limiting block 9 at the bottom of the thread block 8 slides in the opposite direction along the limiting groove and returns to the initial position. When the thread block 8 moves in the opposite direction, the transmission rod 11 pulls the second inclined block 12 to move inward. The second inclined block 12 disengages from the inclined side of the first inclined block 4, and the original vertical downward clamping force disappears. The limiting slider and the lower mold are no longer constrained by pressure, and the lower mold can be removed and replaced.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
