Mold design and manufacturing technology made progress in recent years, the median is no longer the limit workers die design and manufacture of the key. This paper analyzes the spring destroyed hold multiposition progressive die design process of detailing the layout of its programs and forming multiposition design of progressive die ponents. Reasonable steps to determine the shape and multiposition progressive die structure, the mold insert block die by a certain extent, reduce the cost, and easy replacement of wearing parts. Mold structure flexible and reliable, easy to discharge, to ensure product quality, of such part of the progressive die design a valuable reference.
