[0031] In this embodiment, specifically, the opening distance of the V-shaped exhaust groove is set between 5-10 mm, and the groove depth is controlled within the range of 1.5-4 mm, which not only ensures that the gas can be discharged smoothly, but also avoids the manufacturing difficulty and cost increase caused by too large an opening and too deep a groove depth.

[0032] In this embodiment, specifically, the V-shaped angle of the V-shaped exhaust groove is set at 100 degrees to 150 degrees, which helps the gas to form a stable flow in the groove, reduce eddy currents and turbulence, and improve exhaust efficiency.

[0033] In this embodiment, specifically, in S1, a high-temperature alloy or a ceramic-based composite material is selected to make the exhaust groove to ensure that it can still maintain good performance in a long-term high-temperature environment.

[0034] In this embodiment, specifically, in S2, a three-dimensional flow field model is established according to the actual structure and size of the mold, and the initial conditions and boundary conditions of the flow field simulation are set according to the physical properties of the aluminum liquid and the process conditions. Fluid dynamics software is used to perform simulation calculations to obtain simulation results of the aluminum liquid flow and gas discharge process inside the mold. The simulation results are analyzed to find out the key factors affecting the exhaust efficiency, and optimization suggestions are put forward.

[0035] In this embodiment, specifically, in S3, a mold sample is made according to the optimized design scheme, and an efficient exhaust groove system is embedded, a wheel hub production experiment is carried out on the mold sample, and data in the production process such as exhaust conditions, product quality, etc. are recorded.

[0083] 6. Experimental expansion and optimization

[0084] Multivariate Experiments:

[0085] On the basis of basic experiments, multivariate experiments can be further designed to explore the influence of corresponding casting parameters (such as temperature, pressure, injection speed, etc.) on the performance of high-efficiency exhaust slot system. By adjusting these parameters, observing and recording the changes in exhaust efficiency, casting quality and other indicators, the optimal casting process conditions can be found.

[0086] Long-term stability test:

[0087] To verify the long-term stability and durability of the high-efficiency exhaust slot system, a long-term continuous operation experiment can be designed. During the experiment, the performance changes, maintenance requirements and any potential failure modes of the system are recorded. This helps to evaluate the reliability of the system and provide guidance for subsequent product maintenance and care.

[0092] Cost-Benefit Analysis:

[0093] During the experiment, the manufacturing cost, operating cost and economic benefits (such as improving casting quality, reducing scrap rate, etc.) of the high-efficiency exhaust slot system are recorded and analyzed. Through cost-benefit analysis, the economic feasibility of the system can be evaluated and support can be provided for the company's decision-making.

[0094] In this embodiment, specifically, the experimental results are analyzed as follows:

[0095] (1) Exhaust efficiency

[0096] Traditional exhaust slot system:

[0097] In the experiment, it was observed that the traditional venting groove system was unable to handle the gas deep in the mold cavity. Due to the non-optimal design of the venting groove, the gas was easily retained deep in the cavity during the filling process and could not be discharged in time. This situation led to a significantly increased risk of defects such as pores and shrinkage forming inside the casting. The pores not only affect the appearance quality of the casting, but also weaken its mechanical properties, while shrinkage may cause cracks or fractures in the casting during subsequent processing or use.

[0098] High efficiency exhaust slot system:

[0099] In contrast, the high-efficiency exhaust groove system significantly improves the exhaust efficiency through precise calculation and optimized design. Its unique exhaust groove position and shape design allow the gas to be discharged smoothly along the preset path, reducing gas retention. Experimental data show that under the same casting conditions, the exhaust efficiency of the high-efficiency exhaust groove system is about 30% higher than that of the traditional system (this value is an example, the actual data may be corresponding). This improvement not only reduces the incidence of internal defects in castings, but also improves the overall stability and reliability of the mold.

[0100] (2) Casting quality

[0101] Traditional exhaust slot system:

[0102] Due to internal defects in castings caused by poor exhaust, the quality of castings produced by traditional exhaust groove systems is generally low. In the experiment, we detected obvious pores and shrinkage marks on the surface of the castings, and the internal structure was not dense enough. These defects not only affected the appearance of the castings, but also reduced their mechanical properties and service life. In addition, the high scrap rate also increased production costs and reduced production efficiency.

[0103] High efficiency exhaust slot system:

[0104] The application of the efficient exhaust groove system has significantly improved the quality of castings. Experimental results show that the defects such as internal pores and shrinkage in castings produced by this system are significantly reduced, the surface finish is higher, and the internal structure is denser. This high-quality casting not only meets the customers' high requirements for product quality, but also improves the market competitiveness of the products. At the same time, the reduction in scrap rate also reduces production costs and improves production efficiency.

[0105] (3) Production efficiency

[0106] Traditional exhaust slot system:

[0107] Due to the many casting defects and high scrap rate, the traditional exhaust groove system needs to be frequently stopped to inspect and repair the mold during the production process, which not only increases the production cycle but also reduces production efficiency. In addition, the shutdown inspection may also cause other links of the production line to wait or idle, further reducing the overall production efficiency.

[0108] High efficiency exhaust slot system:

[0109] The application of the efficient exhaust slot system has significantly improved production efficiency. Due to the reduction of casting defects and scrap rate, the number of times the production process needs to be stopped for inspection and repair of molds has also been reduced accordingly. This enables the production line to operate more stably and reduces waiting and idle time. Experimental data show that under the same conditions, the production efficiency of the production line using the efficient exhaust slot system is about 20% higher than that of the traditional system (this value is an example, and the actual data may be corresponding). This improvement not only shortens the production cycle, but also improves the production line's capacity utilization and overall benefits.

Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
