Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a camera eyepiece rear shell mold. Background Technology

[0002] In the field of modern optical imaging technology, camera modules have stringent requirements for the precision and surface quality of plastic hemispherical components. These components are widely used in products such as mobile phone cameras, security monitoring equipment, and vehicle camera systems. Their molding quality directly affects the optical performance and imaging effect of the lens. In the process of plastic hemispherical injection molding, the precise docking and positioning of the upper mold base and the lower mold base plays a decisive role in the product molding quality and production efficiency. Currently, traditional camera eyepiece back shell molds mostly use rigid positioning structures when positioning the mold base. Although this structure can achieve the positioning function, in actual operation, due to the lack of a buffer mechanism, the upper and lower mold bases are prone to rigid contact and collision during the mold closing process. This not only reduces the assembly accuracy of the mold and affects the molding quality of the product, but also leads to accelerated mold wear, shortens the mold's service life, and increases the company's production costs. Existing molds also neglect the protection of the sprue bushing position, which can easily allow dust and dirt to enter the mold from the sprue bushing, affecting the mold's processing quality and accuracy. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0003] The purpose of this utility model is to provide a camera eyepiece rear shell mold to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: Design a camera eyepiece rear shell mold, including an upper mold base, a lower mold base, a positioning component and a protective component. The upper mold base is provided with a sprue sleeve at its upper end. The lower mold base is provided with a limit seat at its center and an inner mold is provided inside the limit seat. The positioning component is provided at the four corners of the lower mold base. The protective component is provided outside the sprue sleeve. The positioning component includes a positioning sleeve and a fixing base. The positioning sleeve is fixed inside the lower mold base and has a first spring inside. A positioning rod is connected to the first spring and the positioning rod is inserted into the positioning sleeve. The protective assembly includes a mounting base, a movable block rotatably disposed on the inner side of the mounting base, a protective cover fixed on one side of the movable block, and an electric motor connected to the outer side of the protective cover and the electric motor fixed on the outer side of the mounting base.

[0005] Preferably, the fixed seat is fixed to the side of the limiting seat and has a guide rod that moves through it. The guide rod is fixed to the lower mold base. A second spring is connected between the inner side of the fixed seat and the lower mold base. An outer stop is provided at the outer end of the guide rod.

[0006] Preferably, the positioning sleeve has three sets of side blocks on its side, and the side blocks are embedded in the lower mold base and are threadedly connected to the lower mold base with fixing bolts.

[0007] Preferably, a sealing ring is provided on one side of the mounting base, and the sealing ring is fixed to the outside of the sprue sleeve and fits against the inside of the protective cover.

[0008] Preferably, a sealing gasket is provided at the lower end of the protective cover, and the sealing gasket is attached to the upper surface of the upper mold base.

[0009] Preferably, the lower end of the mounting base is provided with three sets of mounting holes, and mounting bolts are threadedly connected between the mounting holes and the upper mold base.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features a positioning component within the device. By pressing the first spring with a positioning rod and retracting it into the positioning sleeve, and by moving the fixed seat on the guide rod to press the second spring, it can achieve precise docking and positioning of the upper and lower mold bases. This ensures that the mold bases are quickly and accurately aligned, while avoiding direct rigid contact between the upper and lower molds that could cause collisions. This effectively improves the assembly accuracy and stability of the mold, reduces safety hazards during equipment use, and ensures the service life and production safety of the mold. It also provides elastic buffering between the limiting seat and the inner mold, preventing compression and wear on the inner mold.

[0011] 2. This utility model has a protective component installed inside the device. The moving block and the protective cover are rotated by a motor, so that the protective cover is fitted on the outside of the sprue sleeve and the sealing ring. This can achieve external sealing protection for the sprue sleeve, which can isolate it from dust and dirt during non-use periods. This prevents the mold from being corroded by dust and dirt inside the mold, resulting in mold wear or loss of precision, thus improving the safety and practicality of the equipment.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1 As shown in Figure 4, this embodiment provides a camera eyepiece rear shell mold, including an upper mold base 1, a lower mold base 2, a positioning component 4, and a protective component 6. The upper mold base 1 is provided with a sprue sleeve 5 at its upper end. The lower mold base 2 is provided with a limiting seat 21 at its center and an inner mold 3 is provided inside the limiting seat 21. The positioning component 4 is provided at the four corners of the lower mold base 2, and the protective component 6 is provided outside the sprue sleeve 5. In this embodiment, the positioning component 4 includes a positioning sleeve 41 and a fixing seat 46. The positioning sleeve 41 is fixed inside the lower mold base 2 and has a first spring 42 inside. A positioning rod 43 is connected to the first spring 42 and is inserted into the positioning sleeve 41. The fixing seat 46 is fixed to the side of the limiting seat 21 and has a guide rod 47 that moves through it. The guide rod 47 is fixed to the lower mold base 2. A second spring 48 is connected between the inner side of the fixing seat 46 and the lower mold base 2. An outer stop block 49 is provided at the outer end of the guide rod 47. Three sets of side blocks 44 are provided on the side of the positioning sleeve 41. The side blocks 44 are embedded in the lower mold base 2 and are connected to the lower mold base 2. The threaded connection has a fixing bolt 45. The positioning rod 43 compresses the first spring 42 and retracts it into the positioning sleeve 41. The fixing seat 46 moves on the guide rod 47 to compress the second spring 48. This can achieve precise docking and positioning of the upper mold base 1 and the lower mold base 2, ensuring that the mold base is quickly and accurately aligned. At the same time, it avoids direct rigid contact between the upper and lower molds, which can cause collisions. This effectively improves the assembly accuracy and stability of the mold, reduces safety hazards during equipment use, and ensures the service life and production safety of the mold. It can also provide elastic buffering between the limit seat 21 and the inner mold 3, preventing squeezing and wear on the inner mold 3. In this embodiment, the protective component 6 includes a mounting base 61, a movable block 62 rotatably disposed on the inner side of the mounting base 61, a protective cover 63 fixed on one side of the movable block 62, a motor 64 connected to the outer side of the protective cover 63 and fixed to the outer side of the mounting base 61, a sealing ring 65 disposed on one side of the mounting base 61, the sealing ring 65 fixed to the outer side of the sprue sleeve 5 and fitted to the inner side of the protective cover 63, a sealing gasket 66 disposed at the lower end of the protective cover 63, the sealing gasket 66 fitted to the upper surface of the upper mold base 1, and three sets of mounting holes 67 disposed at the lower end of the mounting base 61, with mounting bolts 68 threadedly connected between the mounting holes 67 and the upper mold base 1. The movable block 62 and the protective cover 63 are driven to rotate by the motor 64, so that the protective cover 63 is fitted onto the outer side of the sprue sleeve 5 and the sealing ring 65, which can achieve external sealing protection for the sprue sleeve 5, and facilitate the isolation of dust and dirt during non-use, preventing the mold interior from being corroded by dust and dirt, resulting in mold wear or precision deterioration, and improving the safety and practicality of the equipment.

[0017] The working principle and process of this utility model are as follows: In use, the upper mold base 1 and the lower mold base 2 are installed accordingly. The upper mold base 1 is inserted into the positioning rod 43 and squeezes the first spring 42 to retract. During the pressing down of the upper mold base 1, the limiting seat 21 is pushed to move inward and clamps and positions the inner and outer molds. The fixed seat 46 moves on the guide rod 47 and squeezes the second spring 48 to retract. This can avoid the upper and lower molds from directly contacting each other and causing collisions. It can also provide elastic buffering between the limiting seat 21 and the inner mold 3. During non-use, the moving block 62 and the protective cover 63 are driven to rotate by the motor 64, so that the protective cover 63 is sleeved on the outside of the sprue sleeve 5 and the sealing ring 65. This can achieve external sealing protection for the sprue sleeve 5 and prevent the mold from being corroded by dust and dirt inside the mold, which can cause mold wear or precision deterioration.
