Problems solved by technology

[0002] When the die is stamping metal, due to the high strength and instantaneous high temperature, the metal parts will be clamped on the punch, and the upper punch can be knocked off by using the inner stripping plate. Due to the particularity of the lower punch, It is impossible to use the inner stripping plate to return the stamping parts, and the parts need to be manually stripped, which is easy to cause accidents

Abstract

The invention discloses a lower die holder with an external stripping plate, relating to a punching die. The lower die holder with the external stripping plate comprises the lower die holder, wherein the lower die holder is provided with a lower liner plate; the lower liner plate is provided with a lower punching head; the lower die holder, the lower liner plate and the lower punching head are connected with one another through fixing pins; the lower liner plate is further provided with the external stripping plate; the lower punching head passes through the center of the external stripping plate; and the external stripping plate is connected with the lower die holder through a spring. The invention has the advantages that: the lower punching head moves downwards after punching, and a metal piece is blocked by the external stripping plate and is separated from the lower punching head without manual operation.

Description

technical field [0001] The invention relates to a stamping die, in particular to a lower mold base of the stamping die. Background technique [0002] When the die is stamping metal, due to the high strength and instantaneous high temperature, the metal parts will be clamped on the punch, and the upper punch can be knocked off by using the inner stripping plate. Due to the particularity of the lower punch, It is impossible to use the inner stripping plate to return the stamping parts, and the parts need to be manually stripped, which is easy to cause accidents. Contents of the invention [0003] The present invention is just to solve the above-mentioned problems, and provides a lower mold base with an outer stripping plate that can realize the automatic falling off of metal parts after stamping. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A lower mold base with an outer stripping plate, comprising a low...
