Abstract

A kind of punching die of keyboard of notebook computer framework, upper die and lower die, upper mould includes the upper bolster being sequentially connected, upper mould fixed plate, piercing punch and stripper, lower mould includes the die shoe being sequentially connected, lower mold fixed plate and combined die, the piercing punch includes the first drift area and the second drift area, the first drift area is provided with multiple drifts for the non-conterminous part keyhole of punching, the second drift area is provided with the drift of punching surplus keyhole, the combined die is provided with the first die being engaged with the first drift area, the second die being engaged with the second drift area.The mould structure is simple, and punch process is divided into two steps, rushed keyhole dispersed placement in often walking, and reduces impulsive force suffered by framework, reduces framework and keyhole deformation, side stress in keyhole connecting portion each punching step, reduces which and ruptures;First drift area and the second drift area are concentrated on a piercing punch, once carry out two keyboard frame high punching efficiency.

Description

The punching die of keyboard of notebook computer framework
Technical field
This utility model belongs to mould applications, specifically related to a kind of punching die of keyboard of notebook computer framework.
Background technology
The keyboard frame of quite a few notebook computer is stamped and formed out by metal shell at present.Due to key on keyboard frame Hole is more, densely distributed, and during disposable punching molding, impulsive force great Yi causes keyhole deformation to subside, and due between keyhole Connecting portion is narrower, connecting portion both sides synchronous punching in punch process, is easily caused connecting portion fracture.Current keyboard of notebook computer Frame mold structure is complicated, and product quality has much room for improvement.
The content of the invention
Problem to be solved in the utility model is:A kind of punching die of keyboard of notebook computer framework is provided.
To solve the above problems, the technical scheme that this utility model is provided is:A kind of keyboard of notebook computer framework is rushed Punch die, for the punching keyhole on keyboard frame, including upper die and lower die, the upper mould includes what is be sequentially connected from top to bottom Upper bolster, upper mould fixed plate, piercing punch and stripper, die shoe that the lower mould includes being sequentially connected from bottom to top, lower mould Fixed plate and combined die, in the technical program, the piercing punch includes the first drift area and the second drift area, described first Drift area is provided with multiple drifts for the non-conterminous part keyhole of punching, and the second drift area is provided with punching surplus keyhole Drift, the combined die are provided with the first die being engaged with the first drift area, are engaged with the second drift area The second die.The mould carries out two keyboard frame stamping parts synchronization punching simultaneously, and the first drift area is coordinated with the first die A part of non-conterminous keyhole is gone out on first keyboard frame, the second drift area is coordinated in second keyboard with the second die The complementary keyhole of correspondence disappearance on first keyboard frame is gone out on framework, first time punching press is completed, then the first keyboard frame With with the second keyboard frame transposition, the punching press of remaining keyhole is completed on each comfortable two keyboard frame.The punching die structure Simply, punch process is divided into two steps, and in often walking, rushed keyhole Monodispersed arrangement, reduces impulsive force suffered by framework, reduce Framework and keyhole deformation, and side stress in keyhole connecting portion each punching step, reduce its fracture;While first Drift area and the second drift area are concentrated on same piercing punch, once carry out two keyboard frame synchronous punchings, efficiency high.
Further, the drift that the stripper is provided with the first drift area and the second drift area arrange is corresponding Through hole, the drift extend out on the downside of the stripper through the through hole.
Further, the stripper is slidably connected with the upper bolster Jing bolts, and bindiny mechanism is simply easily achieved.
Further, the keyboard frame is preset with some location holes, the first die of the combined die and second recessed The alignment pin being engaged with the location hole is equipped with mould.After the setting of alignment pin facilitates keyboard frame stamping parts exchange position Positioning, improves keyhole positional precision.
The utility model has the advantages that:
1. the punching die structure is simple, and keyhole punching process is divided into two steps, and in each step, rushed keyhole is divided equally Distribution is put, and reduces impulsive force suffered by keyboard frame stamping parts, reduces the deformation of framework and keyhole;Keyhole connecting portion each A side stress in punching step, so as to reduce its fracture;First drift area and the second drift area are concentrated located at same punching simultaneously On the punch of hole, two keyboard frame synchronous punchings, efficiency high are once carried out.
2. stripper simple structure, connected mode are easily achieved, and the setting of alignment pin facilitates framework stamping parts exchange position After position, improve punching keyhole positional precision.
