Die casting companies share die casting process tips
Due to the different molds, process conditions and materials of die castings, the particularity and complexity of casting production are caused. There are many technical skills in production, which have an important impact on the quality of castings. Through the accumulation of die-casting process methods in production, below, die-casting companies summarize and analyze these methods.
The consistency of casting stock benchmarks affects machining accuracy
With the rapid development of the die-casting industry, people have a deeper understanding of the pressing process of die-casting parts through the summary of die-casting production practices. Die casting companies said that the process and quality rules for hot and cold processing of die casting parts are more perfect, fully recognizing the importance of the same benchmark.
1. Drawing and countersigning of blank drawings of die-casting parts
In the preparation process of die casting production, according to the feasible product part drawings reviewed, the engineer will draw and sign the product part casting drawings, and the design quality of the blank drawings should be scientifically and clearly reflected in the drawings. The die-casting company said that the process scheme, technical quality requirements, position and dimensional tolerance, machining allowance, casting inclination, parting position, mold ejection position and important dimensional reference position are very important for the processing positioning and clamping of the product, which directly affect the processing quality and accuracy. Casting drawings are the quality control standard documents for the entire die casting process, and are also the basis for process mold design, mold cleaning and processing fixture design.
2. Mold size benchmark to ensure
The mold design should be strictly controlled in accordance with the casting drawing datum, the datum plane should have no draft angle, and the datum plane should be designed on the side parallel to the mold parting surface as much as possible. Important dimensions should not be designed on molds that form movable sliders. The molding of castings and separation from the mold need to be smoothly formed, and the design of the cold and heat temperature control device ensures the balance of cold and heat, all in order to prevent serious stress deformation of castings. For a multi-cavity design, separation marks should be used, which is conducive to processing.
3. Benchmark verification of casting process
According to the die casting company, the die casting process is a verification of the blank processing benchmark and machining allowance. It is required to be processed in strict accordance with the casting drawings approved by the countersignature to ensure dimensional stability. Because it plays an important role in the sizing of the die-casting mold and the trial processing of blanks, fixtures and fixtures should also be standardized, die-casting companies believe that only in this way can the mass production quality be stabilized and the processing accuracy of qualified die-castings can be produced.
Die casting companies remind that casting production needs to obtain qualified blanks, and the uniform and reasonable determination of benchmarks is very important for precision casting production. Arbitrary selection of benchmarks will cause problems such as difficult processing, out-of-specification position size, and insufficient processing allowance, resulting in high scrap rate and large mass production losses. Therefore, the importance of the consistency of blank and processing benchmark is an important part of casting process design and needs to be paid attention to.
