Method for rapidly making CH hole in manufacturing process of stamping die and device thereof

Abstract

The invention provides a method for rapidly making a CH hole in a manufacturing process of a stamping die and a device thereof, belonging to the technical field of die manufacturing and solving the problems of high developing cost and complicated operation of the existing traditional method for manufacturing a mould of the CH hole. The method comprises the following steps of: A, preparing a hollow die and a terrace die; B, forming holes; and C, demolding. The device for rapidly making the CH hole in the manufacturing process of the stamping die comprises a hollow die of the stamping die and a terrace die of the stamping die, wherein a plurality of bottom holes, a plurality of ejecting bodies in one-to-one correspondence with the bottom holes are fixed on the terrace die of the stamping die, and the ejecting bodies are made of nonmetal elastic materials. The invention has the advantages of short developing period, developing cost saving, simple structure, easy operation and the like.

Description

technical field [0001] The invention belongs to the technical field of mold manufacturing, and in particular relates to a method and a device for quickly making CH holes in the stamping mold manufacturing process. Background technique [0002] In the manufacturing process of the stamping die, in order to meet the purpose of ensuring the accuracy of the parts during the debugging stage of the stamping die, it is necessary to process the CH hole during the drawing process. The CH hole refers to the process hole for mold research. It is not the hole on the final product required by the user, but the process hole used in the manufacture of the mold for debugging. At present, in the development and debugging stage of the stamping die, in order to ensure the precision of the stamping die, it is necessary to design the CH hole punch and die in the drawing sequence to punch out the CH hole on the part as a unified positioning reference for the subsequent part manufacturing, so as to...

AI Technical Summary

Problems solved by technology

[0003] 1. This structure needs to provide CH hole convex and concave molds, which increases the cost of mold development

2. It is necessary to process the CH hole convex and concave mold installation holes on the mold and assemble the CH hole convex and concave molds, which increases the workload of processing, assembly and debugging

3. After the mold debugging is completed, the CH hole convex and concave molds need to be disassembled, and the installation holes of the CH hole convex and concave molds need to be repaired and welded, which increases a lot of mold processing and manufacturing time
