Pressure casting (die casting) after the promotion of the use of the machinery manufacturing industry product design process is more rationalized, to a large extent, to get rid of the shortcomings of the traditional manufacturing process, but after a period of time the use of the die casting mold also found that the defects exist in their own limitations on the improvement of product quality, therefore, the design of the die casting molds and die casting process improvement of the casting industry need to think positively about the problem.

First, the basic design process of die-casting mold

The first is to analyze the characteristics and nature of the die casting. For different models and different kinds of die casting, design die casting mold specific process should also reflect the difference. Therefore in the die casting die optimization design before, the key is to judge the overall structure of the die casting, material characteristics, internal quality, dimensional accuracy and other characteristics, and then can choose the right kind of die casting die. Mold designers by judging the basic nature of the die casting, should be able to give the corresponding three-dimensional design model, and then simplify the mold design and mold forming specific technical solutions. Second is for assembling die casting mold drawings for accurate drawing. Improve the core measures of the mold design lies in the scientific drawing operation, especially for the assembly die casting mold sketches. After the cost estimation, for all kinds of die-casting mold cost can be rough judgment. Die casting mold assembly operation point is to avoid mold inherent internal defects, and according to the corresponding molding order to deal with. On this basis, the mold designers also use the comprehensive comparison of the way to screen the mold design scheme, to ensure that the mold design drawings can be determined, so as to realize the mold manufacturing cost effectively reduce and mold production efficiency to enhance the goal. The third is to track the production summary. Responsible for the design of die-casting mold technicians should not only complete the preliminary drawings and mold design work, and also do the whole tracking mold production. Mold designers only in ensure tracking mold production and manufacturing on the basis of in-depth understanding of die casting die existing design defects and loopholes, and then the corresponding amendments. And, mold designers also have to go through the detailed process induction and summary, make sure to give to improve the die-casting efficiency and simplify the die-casting operation process feasible suggestions, avoid the inherent structural defects of die-casting mold.

Second, improve the necessity of die casting mold design process

From the perspective of machinery manufacturing, die casting process should belong to the key mechanical production process. Into the new period, information technology has been able to penetrate the casting industry production, so as to simplify the casting process operation, reduce the cost of die casting mold and ensure the accuracy of the process operation effect. But up to now, about die casting mold equipment in specific design, if lack of necessary design process improvement will be manifested as a variety of equipment operation defects. In serious cases, die casting mold equipment may also suddenly appear failure situation, and then threaten the die casting production. Therefore, it can be learned, at present for the basic design of die casting die way to be optimized accordingly. For example, in the specific link of die casting production, die casting die if fatigue failure state, may cause the mold itself is damaged or destroyed. Certain molds after sustained long-term operation, die casting die internal will slowly crack, eventually lead to damage die casting die steel structure phenomenon. In the fatigue factor caused by die casting die damage accident, heat fatigue phenomenon constitutes the most critical mold damage factors. In addition, the die casting mold may also be damaged by corrosion damage or broken damage, so as to cause interference to the die casting production. Therefore, in order to avoid the above damage phenomenon, then at present for die casting die important die casting process equipment should be committed to optimize the design, ensure the use of scientific process design to improve the die casting die of the overall equipment performance.

The above is about die-casting mold design and improve the key points of the discussion.
