Description

Technical Field

[0001] This utility model relates to the field of camera bracket demolding technology, and in particular to a camera bracket demolding mechanism. Background Technology

[0002] As a crucial component of automotive electronic systems, the bracket structure of in-vehicle cameras directly impacts assembly reliability. Current camera brackets are manufactured using injection molding; however, they are prone to issues such as… Figure 1 In the camera bracket structure shown, the camera mounting part adopts an arc-shaped dome design. During the mold demolding process, due to the lack of support, this structure is prone to irregular deformation when the mold core is detached. This structural deformation can cause problems such as camera module positioning offset and abnormal gaps at the joint surfaces in subsequent assembly processes. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a camera bracket demolding mechanism that can minimize the deformation of the camera mounting part.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a camera bracket demolding mechanism, including a mold core and a demolding component, wherein the top surface of the mold core is provided with a first cavity, and the mold core is provided with a plurality of through holes extending from its top surface to the ground, wherein at least some of the through holes have their openings on the top surface of the mold core located within the first cavity;

[0005] The demolding assembly includes a guide slide and a support rod. The guide slide has a ramp and a clearance hole is provided on the ramp along the slope direction. The bottom of the mold core is slidably disposed on the guide slide along the slope direction. The support rod passes through the clearance hole and the through hole in sequence. The mold core and the support rod are slidably disposed relative to each other.

[0006] Furthermore, the ramp is provided with a T-shaped guide rail, and the mold core is provided with a groove adapted to the T-shaped guide rail.

[0007] Furthermore, the mold core is provided with a T-shaped block, and the ramp is provided with a groove adapted to the T-shaped block.

[0008] Furthermore, the slope of the ramp is between 25° and 45°.

[0009] Furthermore, the slope of the ramp is 30° to 40°.

[0010] Furthermore, the demolding assembly also includes a base, and the support rod is fixedly mounted on the base.

[0011] Furthermore, the mold core and the support rod are either clearance-fitted or transition-fitted.

[0012] Furthermore, the top surface of the mold core is provided with a second cavity.

[0013] Furthermore, the mold core is provided with a core, which is located in the second cavity.

[0014] The beneficial effects of this invention are as follows: A through hole is provided on the mold core for the support rod to pass through, and the mold core and support rod are slidably disposed relative to each other, while the mold core is slidably disposed on the slope of the guide slide. Because the guide slide has a clearance hole to avoid the support rod, it is driven to move horizontally along both ends of the slope, allowing the mold core to move vertically. Furthermore, during demolding, by moving the guide slide, the mold core descends, completing the separation of the mold core from the camera mounting part. Simultaneously, the support rod can also support the camera mounting part, thereby minimizing the deformation of the camera mounting part. Attached Figure Description

[0024] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] Please refer to Figures 2 to 4As shown, this utility model discloses a camera bracket demolding mechanism, including a mold core 1 and a demolding assembly 2. The top surface of the mold core 1 is provided with a first cavity 11, and the mold core 1 has multiple through holes 12 extending from its top surface to the ground. At least some of the through holes 12 are located within the first cavity 11 on the top surface of the mold core 1. The demolding assembly 2 includes a guide slide 21 and a support rod 22. The guide slide 21 has a slope, and the slope has clearance holes 211 along the slope direction. The bottom of the mold core is slidably disposed on the guide slide 21 along the slope direction. The support rod 22 passes through the clearance holes 211 and the through holes 12 in sequence, and the mold core 1 and the support rod 22 are slidably disposed relative to each other.

[0026] Working principle: During the injection molding process, the camera mounting part 51 of the camera bracket 5 will be formed in the first cavity 11. At this time, the camera mounting part 51 is supported by the mold core 1 and the support rod 22.

[0027] During the demolding process, the guide slide 21 is moved so that the mold core 1 moves downward relative to the support rod 22, thereby completing the separation of the mold core 1 from the camera mounting part 51. At the same time, the support rod 22 can also support the camera mounting part 51, thereby minimizing the deformation of the camera mounting part 51.

[0028] It is worth noting that the clearance fit or transition fit between the mold core 1 and the support rod 22 can ensure the relative sliding between the mold core 1 and the support rod 22.

[0029] In one alternative implementation, please refer to Figure 2 As shown, a T-shaped guide rail 3 is provided on the slope, and a groove 4 adapted to the T-shaped guide rail 3 is provided on the mold core 1. The cooperation between the T-shaped guide rail 3 and the groove 4 can ensure the direction of movement of the mold core 1 on the slope.

[0030] In another optional embodiment, the mold core 1 is provided with a T-block (not shown in the figure), and the ramp is provided with a groove adapted to the T-block. The cooperation between the T-block and the groove ensures the direction of movement of the mold core 1 on the ramp.

[0031] In some implementations, please refer to Figure 4 As shown, the slope of the ramp is A. By limiting the slope of the ramp, the smooth movement of the mold core 1 on the ramp is ensured. This includes, but is not limited to, A being 25°, 30°, 35°, 40°, or 45°.

[0032] In some implementations, please refer to Figures 2 to 3As shown, the demolding assembly 2 also includes a base 23, and the support rod 22 is fixedly mounted on the base 23. The base 23 is used to fix the support rod 22 to prevent the support rod 22 from moving when the mold core 1 moves.

[0033] In some implementations, please refer to Figure 3 As shown, the top surface of the mold core 1 is provided with a second cavity 13. The second cavity 13 can be used to injection mold other components on the camera bracket 5, such as screw posts 52 and positioning posts 53 used for assembling the camera.

[0034] In some implementations, please refer to Figure 3 As shown, the mold core 1 is provided with a core 14, which is located in the second cavity 13. When the screw post 52 and the positioning post 53 are injection molded in the second cavity 13, the core 14 can be used to form assembly holes for assembly on the screw post 52 and the positioning post 53.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
