The utility model relates to a flexible line way board makes technical field, more specifically relates to a change old mould structure, including upper die base, die holder, from the upper strata to the lower floor between upper die base and the die holder has set gradually solid faller, stripper and die board, still including dashing the needle, it is in to dash the perpendicular setting of needle solid faller is last and pass the stripper, it is equipped with the auxiliary block in the needle main part to dash of needle. This change old mould structure increases supplementary piece on original basis towards the needle, realizes towards the location effect of needle on solid faller and the guide effect on the stripper through supplementary piece, has guaranteed the die-cut stability of mould, need not to make solid faller and stripper again, greatly reduced change mould expense, save the cost.

Description

Structure for changing old mold

Technical Field

The utility model relates to a flexible line way board makes technical field, more specifically relates to an old mould structure of change.

Background

In the existing manufacturing process of the flexible circuit board, due to the fact that a customer adjusts the local appearance of a flexible circuit board product, a die change is needed for an ordered appearance punching die. And the fixed needle plate, the stripper plate, the concave template and the punching needle of the die need to be replaced for die change, which occupies 85 percent of the die cost and has huge cost.

If the original shape punching opening needs to be enlarged due to the adjustment of the product shape of a client, the existing fabrication hole can be directly used as a positioning reference, the line cutting and the repair are carried out again, a fixed needle plate, a stripper plate and a concave template of a die do not need to be replaced, and the die change cost is low; if the original shape punching opening needs to be reduced due to the adjustment of the product shape of a client, the existing cavity of the template can not be reduced through a reliable process, and only the fixed needle plate, the stripper plate, the concave template and the punching needle can be manufactured again, so that the cost is high. Therefore, in order to save cost, it is necessary to solve the problem of reducing the punching cut.

SUMMERY OF THE UTILITY MODEL

The utility model provides a change old mould structure need not to change original mould unit and can accomplish die-cut, not only reduction of erection time but also save the cost.

In order to solve the technical problem, the utility model discloses a technical scheme is:

the utility model provides a change old mould structure, includes upper die base, die holder, from the upper strata to the lower floor solid faller, stripper and die board have set gradually between upper die base and the die holder, still include towards the needle, it sets up perpendicularly to dash the needle solid faller is last and pass the stripper, it is equipped with the auxiliary block to dash the needle main part of needle.

Preferably, the auxiliary block has a dovetail-shaped cross section.

Optionally, the auxiliary block is provided in plurality.

Preferably, the cavity through hole of the cavity plate corresponds to the cross-sectional shape of the punch pin.

Compared with the prior art, the utility model discloses an old mould structure of change increases the auxiliary block on original basis towards the needle, realizes towards the location effect of needle on solid faller and the guide effect on the stripper through the auxiliary block, has guaranteed the die-cut stability of mould, need not to make solid faller and stripper again, greatly reduced change the mould expense, save the cost.

Detailed Description

The present invention will be further described with reference to the following embodiments. Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; for a better understanding of the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

Fig. 1 to 9 show that the utility model discloses change embodiment of old mould structure, including upper die base 1, die holder 2, from the upper strata to the lower floor set gradually solid faller 10, stripper 20 and die board 30 between upper die base 1 and the die holder 2, still include towards needle 40, towards needle 40 and set up perpendicularly on solid faller 10 and pass stripper 20, towards being equipped with auxiliary block 41 in the needle main part that dashes of needle 40.

In fig. 3, P is the product shape, and 3 is the product left shape before adjustment, corresponding to the punching edge 5; and 4, the shape of the left side of the adjusted product corresponds to the punching edge 6.

The utility model discloses an old mould structure of change increases auxiliary block 41 on original basis towards the needle, realizes towards the location effect of needle on solid faller 10 and the guide effect on stripper 20 through auxiliary block 41, has guaranteed the die-cut stability of mould, need not to make solid faller 10 and stripper 20 again, greatly reduced change the mould expense, save the cost.

As shown in fig. 3 and 6 to 9, the auxiliary block 41 has a dovetail shape in cross section. The dovetail design can achieve better fixing and guiding effects, but it should be noted that the shape of the auxiliary block 41 of the present invention is not limited to the dovetail shape, and all shapes similar to the dovetail shape can be used to increase the fixing effect of the punch pin 40 on the pin fixing plate 10 and the guiding effect on the stripper plate 20.

As shown in fig. 9, a plurality of auxiliary blocks 41 may be provided on the punching pin 40 for modifying the old mold structure to meet the punching openings required for modifying different-shaped products.

As shown in fig. 8, the cavity via of the cavity plate 30 corresponds to the cross-sectional shape of the punch pin 40. The die cavity through holes on the needle fixing plate 10 and the stripper plate 20 are consistent, and the shape and size after punching adjustment are the shape before punching adjustment and the die cavity through hole shape of the concave die plate 30. Further, it can be understood that, since the auxiliary block 41 has a cross-section of a dovetail shape, the shape of the cavity portion on the needle fixing plate 10, the stripper plate 20, and the cavity plate 30 is a dovetail groove type.

The utility model discloses an old mould structure of change has significantly reduced material cost and processing expense, can save about 62.5% change mould line cutting expense, and practical value is big, can also shorten the mould delivery phase by a wide margin. In addition, the structure can be applied to the modification of other dies, and is not limited to dies for punching the shapes of flexible plate products and auxiliary materials.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations to the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
