In the field of injection mold processing, injection mold design holds a pivotal position, and its design quality directly affects the forming effect and performance of the final products. To ensure that injection mold design is scientific and reasonable, the following key aspects must be fully considered:
Firstly, it is essential to fully take into account the process characteristics of plastic raw materials. Different plastic raw materials exhibit significant differences in fluidity, shrinkage rate, and thermal stability, which have a direct impact on the injection molding process. Meanwhile, the molding performance and type of injection molding machines cannot be overlooked. Different models and specifications of injection molding machines vary in parameters such as injection pressure, injection speed, and clamping force, and these factors collectively affect the quality of injection-molded products. Therefore, during the injection mold design process, corresponding design countermeasures must be formulated and implemented based on the characteristics of the plastic raw materials used and the performance of the selected injection molding machine to ensure smooth product forming and quality compliance.
Secondly, the guiding requirements for plastic parts in injection molds are a crucial aspect that needs to be focused on during the design process. The guiding structure plays a key role in the precise opening and closing of the mold and the accurate positioning of parts. A reasonably designed guiding structure can ensure that the mold remains stable during repeated opening and closing operations, avoiding deviations and thus guaranteeing the dimensional accuracy and shape accuracy of injection-molded products. In addition, given that injection molds need to withstand relatively high pressure and temperature changes during the injection molding process and have high requirements for overall strength and stiffness, it is necessary to accurately calculate the working dimensions of the molding parts during the design process. This not only helps to ensure the durability of the mold but also ensures that the injection-molded products produced meet the design requirements.
Thirdly, the requirements for mold testing and repair are also important aspects that must be considered in injection mold design. The design and manufacturing of injection molds are closely related to mold processing, and the quality of mold processing largely determines the success or failure of raw material processing. A high-quality injection-molded product is based on correct design points, which cover all parts and links of the mold and are closely related to the processing quality of the injection mold. During the mold design stage, it is necessary to fully anticipate potential problems that may arise during mold testing and repair and make pre-emptive countermeasures in advance, so that problems can be efficiently solved during subsequent mold testing and repair processes, improving the overall quality and production efficiency of the mold.
