Blanking die capable of conveniently replacing die core

Abstract

The invention relates to a blanking die capable of conveniently replacing a die core. The blanking die comprises an upper die and a lower die, wherein the upper die comprises an upper formwork, an upper fixing plate group fixedly connected to the lower side of the upper formwork, a stripping plate group arranged below the upper fixing plate group, stripping springs pushing the upper fixing plate group and the stripping plate group to be far away from each other and stripping bolts, the stripping plate group is hoisted on the upper formwork through the stripping bolts, a stripping core block isdetachably embedded in the lower side of the stripping plate group, a punch fixing block is detachably embedded in the lower side of the upper fixing plate group, punches are fixed in the punch fixing block, and the punches penetrate through the stripping plate group and the stripping core block; and the lower die comprises a lower formwork, a lower base plate and a knife edge fixing plate whichare fixedly connected from bottom to top in sequence, a concave module is embedded in the middle of the knife edge fixing plate, first blanking holes matched with the punches are formed in the concavemodule, a second blanking hole communicating with the first blanking holes is formed in the lower base plate, and a cavity is formed in the middle of the lower formwork. The blanking die has the effect of reducing the die cost of the production manufacture.

Description

technical field [0001] The invention relates to the technical field of punching dies, in particular to a punching die which can conveniently replace a die core. Background technique [0002] When producing miniature tact switches, the first thing to do is to use a punch press and corresponding molds to punch the copper strips to process the copper strips into terminal strips (that is, materials with miniature tact switch terminals) belt), and then inject the tact switch base on the terminal strip, and then install shrapnel, buttons and upper cover on the tact switch base in sequence, and finally cut the formed tact switch from the terminal strip. [0003] Since different types of miniature tact switches correspond to different terminal strips, and different terminal strips require different molds, after processing one type of terminal strip, if you want to process another terminal strip, It is necessary to disassemble the mold from the punching machine and replace it with a...

Problems solved by technology

[0003] Since different types of miniature tact switches correspond to different terminal strips, and different terminal strips require different molds, after processing one type of terminal strip, if you want to process another terminal strip, It is necessary to disassemble the mold from the punching machine and replace it with another mold. Because the manufacturing cost of the mold is very high, when the manufacturer needs to produce various types of miniature tact switches, it is necessary to manufacture many sets of corresponding molds. , leading to high production costs for manufacturers, how to reduce the cost of molds for manufacturers is an urgent problem to be solved at present
