Precautions for mold parts processing

1. Introduction of core inserting needle 2D, 3D rough machining, non-installation non-working plane processing (including safety platform surface, buffer mounting surface, pressure plate plane, side reference surface). Before semi-finishing, the side reference surface is aligned to ensure accuracy.
2. Before finishing, align the datum surface of the process datum hole, check the insert allowance, and check the machining accuracy. Finishing surface 2D, 3D, side punching surface and hole position, Dongguan mold processing finishing process reference hole and height reference, finishing guide surface and guide hole.
3. For processing key and difficult points, the process should be particularly emphasized, and the processing points need to be combined, and the process should be clearly expressed. The process design is concise and detailed, and the processing content is expressed numerically as much as possible. When the insert needs to be processed separately, pay attention to the process requirements of the processing accuracy.
4. Precautions for mold parts processing: After combined processing, the insert parts that need to be processed separately, the process is installed in the combined processing and the benchmark requirements for separate processing are installed. Springs are easy to damage in mold processing, so choose mold springs with long fatigue life.
5. Introduction of core inserts In recent years, my country's mold industry has grown rapidly at an average rate of more than 15%, which is far higher than the average value-added of national GDP. Among them, precision casting molds account for about 5% of the total output value of various molds, and the annual growth rate is as high as 25%. At present, my country's automobile and motorcycle industries have entered a period of rapid growth, and output has increased substantially for many consecutive years. Especially cars, which are closely related to the precision casting industry, have grown rapidly, increasing the demand for complex and precision casting molds.
