Metal plate stamping mold based on flat demolding

Abstract

The invention discloses a metal plate stamping mold based on flat demolding. The metal plate stamping mold structurally comprises an upper mold, a mold column and a lower mold, wherein the mold columnis embedded on the upper mold and the lower mold, a stamping structure is arranged between the upper mold and the lower mold, the stamping structure is composed of a top plate, a middle plate, a bottom plate and a plate column, the top plate, the middle plate and the plate column are welded, the middle plate is matched with the bottom plate, and a stripping device is arranged on the bottom plate.According to the metal plate stamping mold, the size of the stripping device can be changed during demolding of a plate, an outer square structure or an inner round structure and an inner square structure can be used for transmission, an adjustable outer square frame moves on an outer square cone round so as to reduce the size of the adjustable outer square frame, an adjustable inner square framemoves on an inner square cone round so as to reduce the diameter of a stretching ring, then the mold and the plate cannot be tightly attached during demolding, and during demolding, the phenomena that the plate is enabled to locally move upwards together with the mold and the plate is slightly deformed are avoided.

Description

technical field [0001] The invention relates to the field of molds, in particular to a sheet metal stamping mold based on flat demoulding. Background technique [0002] Metal stamping is the manufacturing process of using a metal stamping die or series of metal stamping dies to form sheet metal into workpieces with three-dimensional dimensional shapes; metal stamping can form sheet metal very efficiently. Metal stamping dies are mounted on a press, and each stroke of the press forms a workpiece. [0003] Prior Art The traditional sheet metal stamping die uses the upper and lower dies under the action of the press to realize the punching process using the upper and lower dies to realize the cutting of the sheet. How to improve the quality of the sheet during this process is an issue that needs to be improved in the prior art Places, such as: when the plate is demoulded after cutting and stamping, because the mold exerts pressure on the plate during stamping, the mold and the...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the deficiencies of the prior art, to provide a sheet metal stamping die based on flat demoulding, to solve the problem that the traditional sheet metal stamping die uses the upper and lower dies under the action of the press to realize the stamping of the upper and lower dies. The cutting process realizes the cutting of the plate. How to improve the quality of the plate in this process is a place that needs to be improved in the existing technology. Due to the tight fit between the mold and the plate, the partial upward movement of the plate is caused when the mold is demoulded, resulting in the problem of slight deformation of the plate
