Abstract
The utility model discloses a kind of die cutting die for improving combined tolerances, including PFC plates to be punched, the first mould and the second mould, first mould is provided with one group of first alignment pin and one group of first alignment pin, second mould is provided with the second alignment pin corresponding with the first alignment pin, FPC plates to be punched are provided with the first plate hole corresponding with the first alignment pin of the first mould, and the FPC plates to be punched form the second plate hole corresponding with the second alignment pin of the second mould after the punching of the first mould.The second plate hole that FPC plates to be punched and the second mould coordinate in the utility model be by the first mould be punched into come, make the bias direction of the second mould identical with the first mould, allow the secondary nondirectional moulds of script two to become same direction, so as to be constantly shrinking tolerance, reach ± 0.05 requirement.
Description
Technical field
A kind of assembling die is the utility model is related to, particularly relates to a kind of die cutting die for improving combined tolerances.
Background technology
With the development that more becomes more meticulous of electronics industry, to FPC requirement on machining accuracy more and more higher, but mold body is improved
Machining accuracy it is more difficult, particularly combined tolerances control it is increasingly difficult, its main cause is the bias direction of two secondary moulds
It is nondirectional.
As shown in Figure 1 to Figure 3, it is a kind of FPC plate A to be punched, and is punched FPC plates A a kind of assembling die B, C
(Such as Fig. 2, Fig. 3), two groups of positioning holes A1, A2 are disposably got by puncher on FPC plates A to be punched, respectively with first
The secondary secondary mould C of mould B and second registration holes B1, C1 are mutually corresponding, because the machining accuracy of single secondary mould is ± 0.035, and
Die deflection non-directional, therefore the combined tolerances of two width moulds are ± 0.07, this mould can not meet ± 0.05 requirement.
In view of this, the design people is not for attaining many missings caused by improving and not on above-mentioned mould structure design
Just, deeply conceive, and actively research improvement has a fling at and develops and design the utility model.
Utility model content
The purpose of this utility model, which is to provide one kind, can improve FPC plates and rush dimensional accuracy, and improvement simple in construction
The die cutting die of combined tolerances, so as to realize requirement that FPC becomes more meticulous, improve the competitiveness of enterprise.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of die cutting die for improving combined tolerances, it includes PFC plates to be punched, the first mould and the second mould, the
One mould is provided with one group of first alignment pin and one group of first alignment pin, and the second mould is provided with corresponding with the first alignment pin the
Two alignment pins, FPC plates to be punched are provided with the first plate hole corresponding with the first alignment pin of the first mould, and this is to be punched
FPC plates form the second plate hole corresponding with the second alignment pin of the second mould after the punching of the first mould.
First alignment pin is symmetricly set on four angles of the first mould, and the first alignment pin is symmetricly set on first mould
Four angles of tool, have gap between the first alignment pin and the first alignment pin.
After said structure, the utility model is started with from the non-directional deviation of assembling die, improves assembling die public affairs
The problem of difference is too big.The second plate hole that FPC plates to be punched and the second mould coordinate in the utility model is by the first mould
It is punched into and, make the bias direction of the second mould identical with the first mould, allows the secondary nondirectional moulds of script two to become same side
To so as to be constantly shrinking tolerance, reaching ± 0.05 requirement, the utility model reduces the tolerance of assembling die, improved
The dimensional accuracy of FPC plates, the requirement it is achieved thereby that FPC becomes more meticulous, improve the competitiveness of enterprise.

Embodiment
In order to which the technical solution of the utility model is explained further, the utility model is entered below by specific embodiment
Row elaborates.
As shown in Fig. 3 to Fig. 7, the utility model discloses a kind of die cutting die for improving combined tolerances, and it includes waiting to rush
PFC plates 10, the first mould 20 and the second mould 30 cut, the first mould 20 are provided with one group of first alignment pin 21 and one group first
Alignment pin 22, the second mould 30 be provided with 22 corresponding second alignment pin 31 of the first alignment pin, can on FPC plates 10 to be punched
21 corresponding first plate hole 11 of the first alignment pin with the first mould 20 is got by puncher, the FPC plates 10 to be punched pass through
31 corresponding second plate hole 12 of the second alignment pin with the second mould 30 is formed after the punching of first mould 20, as shown in Figure 6.
As illustrated, first alignment pin 21 is symmetricly set on four angles of the first mould 20, the first alignment pin 22 is right
Claim four angles for being arranged on first mould 20, there is gap between the first alignment pin 22 and the first alignment pin 21.
The utility model is started with from the non-directional deviation of assembling die, improves the problem of assembling die tolerance is too big.This
The second plate hole 12 that FPC plates 10 to be punched coordinate with the second mould 30 in utility model is punched into by the first mould 20
Come, have the bias direction of the second mould 30 and the first mould 20 identical, allow originally the two nondirectional moulds of pair become same direction,
So as to be constantly shrinking tolerance, reach ± 0.05 requirement, the utility model reduces the tolerance of assembling die, improves FPC
The dimensional accuracy of plate, the requirement it is achieved thereby that FPC becomes more meticulous, improve the competitiveness of enterprise.
Above-described embodiment and schema and non-limiting product form of the present utility model and style, any art
The appropriate change or modification that those of ordinary skill is done to it, all should be regarded as not departing from patent category of the present utility model.
