Description

Technical Field

[0001] This utility model relates to the field of mold design and manufacturing technology, specifically to a shell cover cutting mold structure for a data transmission optical module. Background Technology

[0002] Data transmission optical modules are core components in modern communication equipment. Their housings are typically made of plastic to provide lightweight design and electromagnetic shielding. During manufacturing, the housing covers of optical modules are generally mass-produced using injection molding. To improve production efficiency and material utilization, injection molds are usually designed with a multi-cavity structure (e.g., producing one or more pairs at a time). Therefore, freshly demolded injection-molded products often contain two or more "housing covers" connected by gates, runners, or connecting ribs, as well as accompanying waste material.

[0003] After injection molding, the product must undergo a trimming (or gate removal, punching) process to separate the paired "outer shell covers" from the waste material at the joint, in order to obtain the final independent product. In existing technologies, the trimming of such thin-walled, precision plastic parts typically presents the following technical challenges: Manual operation is inefficient and risky: Traditional methods rely on manual cutting or breaking using jigs and knives. This method is not only labor-intensive and inefficient, making it difficult to meet the needs of large-scale production; moreover, human factors can easily lead to uneven stress on the product, causing deformation, scratches, or dimensional deviations of the outer casing, and the sharp waste materials pose a safety hazard of cutting operators.

[0004] The positioning and accuracy challenges of automated edge trimming: Existing simple edge trimming dies often lack precise positioning mechanisms when processing one-piece products. If the product experiences even a slight displacement during the trimming process, the punch (cutter) may not accurately align with the trimming groove, thereby damaging the die's cutting edge or causing the product to be scrapped.

[0005] Separating waste from products is difficult: the outer shell structure of optical modules is usually quite complex. After the edges are cut, the waste is easily stuck in the mold or sticks to the product, resulting in poor material discharge and requiring manual secondary cleaning, which reduces the continuity of automated production.

[0006] The mold installation and debugging are complicated: the connection structure between the existing trimming mold and the press is often complicated, and the mold disassembly and assembly takes a long time, which is not conducive to quick mold change and maintenance. Summary of the Invention

[0007] This utility model primarily addresses the shortcomings of existing technologies by providing a cutting mold structure for the outer shell cover of a data transmission optical module. This structure is characterized by its simple structure, convenient operation, good stability, and high efficiency. It solves the problems of low efficiency, poor precision, easy product damage, and inconvenient mold assembly and disassembly during the cutting process of the optical module outer shell cover after injection molding in existing technologies.

[0008] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions: A shell cover cutting edge mold structure for a data transmission optical module includes an injection molded product, which consists of a pair of shell covers and waste material. The injection molded product has a pressure plate at its upper end and a cutting edge plate at its lower end. Both sides of the lower end of the cutting edge plate are provided with pads. A bottom plate is provided between the cutting edge plate and the pads. Both the cutting edge plate and the bottom plate are provided with a pair of cutting edge grooves that communicate with the shell covers.

[0009] Preferably, the lower end of the pressure plate is provided with a pair of punches that are movably inserted and penetrate the cutting groove.

[0010] Preferably, the upper end of the pressure plate is provided with an upper template that is fixed to the pressure plate with screws.

[0011] Preferably, the upper end of the upper template is provided with a press connecting column that is integrated with the upper template, and the press connecting column is connected to the press in a clamp-type insertion connection.

[0012] Preferably, the cutting grooves are symmetrically distributed between the two pads.

[0013] This invention can achieve the following effects: This invention provides a shell cover cut-edge mold structure for a data transmission optical module, which, compared with the prior art, has the characteristics of simple structure, convenient operation, good stability and high efficiency.

[0014] This invention provides a highly efficient edge-cutting device that enables rapid and automatic separation of injection-molded products (outer shell and waste material), replacing traditional manual operation and improving production speed.

[0015] Ensuring cutting precision and product quality: Through precise mold matching, we ensure that the outer shell cover is not damaged or deformed when removing waste material, thus meeting the high precision requirements of the optical module.

[0016] Optimize mold structure for easy maintenance: The reasonable design of the upper and lower mold fit and connection method makes the mold installation stable and easy to disassemble, replace and adjust. Attached Figure Description

[0024] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0025] Example: Figure 1-6 As shown, a shell cover trimming mold structure for a data transmission optical module includes an injection-molded product 2, which consists of a pair of shell covers 10 and scrap material 9. The upper end of the injection-molded product 2 is provided with a pressure plate 4, and an upper template 3 is screwed and fixed to the upper end of the pressure plate 4. An integrated press connecting column 11 is provided at the upper end of the upper template 3, and the press connecting column 11 is clamped and inserted into the press. The lower end of the injection-molded product 2 is provided with a trimming plate 1, and pads 6 are provided on both sides of the lower end of the trimming plate 1. A bottom plate 5 is provided between the trimming plate 1 and the pads 6. Both the trimming plate 1 and the bottom plate 5 have a pair of trimming grooves 8 that communicate with the shell covers 10. The trimming grooves 8 are symmetrically distributed between the two pads 6. The lower end of the pressure plate 4 has a pair of punches 7 that are movably inserted through the trimming grooves 8, and the pressure plate 4 and the punches 7 are fixed by screws.

[0026] Working principle: The object being processed is an injection-molded product 2 consisting of a pair of outer shell covers 10 and scrap material 9. When the press is working, the upper template 3 and pressure plate 4 are pressed down through the press connecting column 11. The pressure plate 4 drives the punch 7 below it to move downward. The injection-molded product 2 is placed on the trimming plate 1, and the punch 7 enters the trimming groove 8. The punching force separates the outer shell cover 10 from the scrap material 9 in the injection-molded product. The base plate 5 and the pad block 6 ensure the strength and positional stability of the mold.

[0027] The following technical effects were achieved: (1) Improve the quality of edge cutting and yield.

[0028] Precise positioning and punching: By setting the cutting groove 8 on the cutting plate 1 and the base plate 5 corresponding to the outer shell cover 10, and cooperating with the punch 7 at the lower end of the pressure plate 4, a precise "punch-die" matching relationship is formed.

[0029] Movable through-hole design: The punch 7 and the cutting groove 8 adopt a "movable plug-in through-hole" structure to ensure accurate cutting edge during punching, cleanly and neatly cut off the connecting waste material, avoid burr generation, and effectively prevent the outer shell cover from deforming or breaking when subjected to uneven force, thereby significantly improving the product yield.

[0030] (2) Improve production efficiency and automation level.

[0031] Dual cutting in one mold: The injection molded product 2 includes a pair of outer shell covers 10. The mold is equipped with a pair of cutting grooves 8 and punches 7. The cutting of two products can be completed in one stamping action, which greatly improves the output per unit time.

[0032] Automatic separation of waste and product: By using the action of the punch 7 through the cutting groove 8, the product and waste are separated at the same time as the waste 9 is cut off, and the material falls smoothly, which is convenient for subsequent automated collection.

[0033] (3) The structure is stable and the stress is uniform.

[0034] Rigid support: A base plate 5 is provided between the cutting plate 1 and the pad block 6, and pad blocks 6 are provided on both sides. This layered support structure greatly enhances the rigidity and stability of the bottom of the mold. During the stamping process, the base plate can effectively disperse the impact force, prevent mold deformation, and extend the service life of the mold.

[0035] (4) Easy to assemble and disassemble, and reliable connection. Modular connection: The pressure plate 4 and the upper template 3 are connected by screws. This split design makes processing and maintenance more convenient. If the punch or pressure plate is damaged, it can be replaced separately, reducing maintenance costs.

[0036] Quick clamping: The upper end of the upper template 3 is equipped with an integrated press connecting column 11, which is fixed to the press using a "clamp-type insert connection". Compared with the traditional bolt and pressure plate fixing method, this design can realize the quick installation and centering of the mold, while also ensuring the firmness of the connection and preventing the mold from loosening during high-frequency stamping.

[0037] In summary, the outer shell cover cutting mold structure for the optical module for data transmission achieves high-quality and high-efficiency cutting of the outer shell cover. At the same time, the clamping process of the mold is optimized by using clamp-type connecting columns. It has the advantages of compact structure, convenient operation, high processing accuracy and long service life.
