After the popularization and application of pressure casting (die casting), the process of product design in the machinery manufacturing industry is more reasonable, and to a large extent, it gets rid of the shortcomings of the traditional manufacturing process.
However, after a period of application, it is also found that the defects of die casting itself limit the improvement of product quality. Therefore, the casting industry needs to think positively about the improvement of die casting design and die casting process.
Firstly, the characteristics and properties of die casting are analyzed. For different models and different types of die casting part, the specific process of die casting design should also reflect the differences.
Therefore, before the optimization design of die casting molds, the key is to judge the overall structure, material characteristics, internal quality, dimensional accuracy and other characteristics of die casting mold, and then to choose the right type of die casting mold.
By judging the basic nature of die casting part, mold designers should be able to give the corresponding three-dimensional design model, and then simplify the mold design and the specific technical scheme of mold forming.
Secondly, it is to accurately draw the drawings of die casting mold to be assembled. The core measure to improve the mold design is to scientifically draw the drawings, especially for the sketch of die casting mold.
After cost estimation, the cost of all kinds of die casting mold can be roughly judged. The key point of operation of die casting mold assembly is to avoid the inherent internal defects of the mold, and to deal with it in accordance with the corresponding forming order.
On this basis, mold designers should also use comprehensive comparison to screen the mold design scheme to ensure that the mold design drawings can be determined, so as to achieve the goal of effectively reducing the manufacturing cost of die casting mold and improving the production efficiency of mold.
The third is to follow up the production summary. Technicians responsible for die casting design should not only complete the early drawing and mold design, but also track the whole process of mold production.
Only on the basis of ensuring the tracking of mold production and manufacturing, mold designers can extract the existing design defects and loopholes of mold, and then make corresponding corrections.
In addition, mold designers should make detailed technological induction and summary to ensure that feasible suggestions are given to improve the efficiency of die casting and simplify the operation process of die casting, so as to avoid the inherent structural defects of die casting mold.
From the perspective of mechanical manufacturing, the pressure casting technology should be a key mechanical production technology. After entering the new era, the information technology has been able to run through the production of the casting industry, so as to simplify the casting technological operation, reduce the die casting cost and ensure the accuracy of the process operation.
However, in the specific design of die casting equipment, if there is the lack of necessary design technology improvement, it will be manifested as a variety of equipment operation defects. In serious cases, die casting equipment may suddenly fail, and then threaten the production of die casting.
Therefore, it can be known that the basic design mode of die casting mold needs to be optimized accordingly. For example, in the specific link of die casting production, if the fatigue failure of die casting mold occurs, the mold itself may be damaged or destroyed.
After continuous long-term operation of some molds, the inside of the die casting mold will slowly crack, and eventually lead to the phenomenon of damaging the steel structure of the die casting mold.
In damage accidents of die casting mold caused by fatigue factors, thermal fatigue is the most critical mold damage factor. In addition, die casting molds may be damaged by dissolution or breakage, which will cause interference to die casting production.
Therefore, in order to avoid the above damage phenomenon, the important die-casting process equipment for die-casting molds should be devoted to optimizing design to ensure the use of scientific process design methods to improve the overall equipment performance of die-casting molds.
