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 mold itself limit the improvement of product quality.
- The basic design process of die casting die.The characteristics and properties of die casting are analyzed. For different models and different types of die casting, the specific process of die casting mold design should also reflect the differences. Therefore, before the optimization design of die casting die, the key is to judge the overall structure, material characteristics, internal quality, dimensional accuracy and other characteristics of die casting die, and then to choose the right type of die casting die. By judging the basic nature of die casting, 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, the drawing of the assembly die casting mold is accurately drawn. The core measure to improve the die design is scientific drawing operation, especially for the sketch of assembling die casting die. After the cost estimation, the cost of all kinds of die casting can be roughly judged. The operation point of die casting mold assembly is to avoid the inherent internal defects of the mold and to deal with them according to the corresponding forming sequence. 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, in order to achieve the goal of effectively reducing the mold manufacturing cost and improving the mold production efficiency. The third is to follow up the production summary. Technicians responsible for die casting mold design should not only complete the early drawing and mold design work, but also do the whole process of tracking 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 process 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 die.
- The necessity of improving die casting die design process.From the mechanical manufacturing point of view, the pressure casting process should belong to the key mechanical production process. After entering the new era, information technology has been able to run through the casting industry production, so as to simplify the casting process operation, reduce the die casting die cost and ensure the accuracy of the process operation. But up to now, in the specific design of die casting equipment, if there is no necessary design process improvement, it will be shown as a variety of equipment operation defects. In severe cases, die casting equipment may suddenly fail, which will threaten die casting production. 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 state of die casting die, it may cause the damage or destruction of the die itself. 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. Thermal fatigue is the most important factor in die casting mold damage accidents caused by fatigue. In addition, die casting die may suffer from corrosion damage or breakage damage, which will interfere with die casting production. Therefore, in order to avoid the above damage phenomenon, the current important die casting process equipment for die casting mold should be committed to the optimization design, to ensure the use of scientific process design to improve the overall equipment performance of die casting mold.
