Factors affecting the structure and system of precision stamping die

1. Cavity layout. Determine the number of cavities and their arrangement according to the geometric structure characteristics of the plastic parts, dimensional accuracy requirements, batch size, difficulty in manufacturing precision stamping molds, and cost. 2. Determine the parting surface. The position of the parting surface should be conducive to mold processing, venting, demolding and forming operations, and the surface quality of the punched parts. 3. Determine the pouring system (the shape, location and size of the main runner, sub-runner and gate) and exhaust system (exhaust method, exhaust slot location, size). 4. Choose the ejection method (ejector, pipe, push plate, combined ejection), determine the undercut treatment method and core pulling method. 5. Determine the cooling and heating method, the shape and location of the heating and cooling groove, and the installation location of the heating element. 6. According to the precision stamping die material, strength calculation or empirical data, determine the thickness and external dimensions of the precision stamping die parts, the external structure and all the connections, positioning and guide positions. 7. Determine the structure of the main forming parts and structural parts. 8. Consider the strength of each part of the mold, calculate the working size of the molded part. The above 8 steps are solved, and the structure of the precision stamping die is naturally solved. Then set out to draw a sketch of the mold structure to prepare for the formal drawing.
