1、 core insert needle introduction 2D, 3D surface rough processing, non-installation non-working plane processing (including safety platform surface, buffer mounting surface, pressure plate plane, side datum surface). Alignment of the side datum surface ensures accuracy before semi-finishing.
2、 before finishing, the datum surface of the process reference hole is straighter, the insert allowance is checked, and the processing accuracy is checked and reviewed. Finishing surface 2D, 3D, side punching surface and hole position, finishing process standard hole and height standard, finishing guide surface and guide hole.3、processing key and difficult points, the process should be particularly emphasized, the need for combined processing, the process is clearly expressed. The process preparation is concise, the expression is detailed, and the processing content is expressed as numerically as possible. When the insert needs to be machined separately, pay attention to the process requirements for machining accuracy.
4、mold parts processing precautions: after combined processing, the connector mould insert parts need to be processed separately, and the benchmark requirements for the process installation of separate processing during combined processing. The spring is easily damaged in mold processing, so it is necessary to choose the mold spring with a long fatigue life.
In recent years, China’s mold industry has grown rapidly at an average rate of more than 15%, 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, China’s automobile and motorcycle industry has entered a period of rapid growth, and the output has increased significantly for many years. In particular, the rapid growth of cars closely related to the precision casting industry has increased the demand for complex and precision casting molds.
