Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping molds for heat dissipation fins of optical modules, and in particular to stamping molds for integral forming of heat dissipation fins of optical modules. Background Technology
[0002] The heatsink fins of optical modules have extremely stringent requirements for forming precision. Even slight dimensional deviations or irregularities in shape can significantly impact the heat dissipation performance of the optical module and the assembly precision with other components. Although the current one-piece stamping process ensures the overall structural precision of the heatsink fins to a certain extent, existing stamping dies still have many shortcomings in meeting the ever-increasing precision requirements of high-end optical modules. Establishing a real-time monitoring and feedback system for die precision is also an important means to improve forming precision. High-precision displacement sensors and pressure sensors are installed in key parts inside the die to monitor the deformation, displacement, and pressure changes of the die in real time during the stamping process. The sensors transmit the collected data to the control system. By analyzing the data, the control system can immediately adjust the stamping process parameters, such as reducing the stamping speed or adjusting the stamping pressure, or issue an alarm to remind operators to maintain and adjust the die in a timely manner, so as to ensure that the die is always in a high-precision operating state and to ensure the stable and reliable forming precision of the heatsink fins.
[0003] Currently, the stamping dies for heat sink fins on the market mainly consist of forming components and guiding components. As a crucial part of the optical module's heat dissipation system, the heat sink fins bear the heavy responsibility of rapidly dissipating heat from inside the optical module to the surrounding environment. Their heat dissipation performance directly depends on the fin's structural design, material selection, and manufacturing process. In terms of structural design, to improve heat dissipation efficiency, heat sink fins typically employ a tall and thin fin structure to increase the heat dissipation area and enhance convective heat transfer with the air. Regarding manufacturing processes, traditional heat sink fin manufacturing methods include casting, machining, and welding. However, these methods have certain limitations in terms of production efficiency, cost control, and product quality. Although casting technology can… While castings can produce heat dissipation fins with complex shapes, defects such as porosity and shrinkage are prone to occur inside the castings, affecting the heat dissipation performance and mechanical strength of the heat dissipation fins. Although machining methods can ensure a certain degree of precision, they are inefficient and costly, making it difficult to meet the needs of large-scale production. The emergence of one-piece stamping technology has provided a new solution for the manufacturing of heat dissipation fins for optical modules. This technology can quickly and efficiently manufacture heat dissipation fins with complex shapes and high precision through one-time stamping, effectively overcoming many drawbacks of traditional manufacturing processes. However, current one-piece stamping dies still reveal some problems in practical applications, making it difficult to fully meet the increasingly stringent performance requirements of the optical module industry for heat dissipation fins.
