Abstract

The utility model discloses a tooling for an FPC (Flexible Printed Circuit) steel die. The tooling comprises a female die, a back gasket, a fixed piece, a lower gasket, a support plate and an outer guide column, wherein the female die is arranged above the lower gasket, the fixed piece is arranged under the back gasket, the upper end of the outer guide column is sequentially connected with the fixed piece, the back gasket and the support plate in a penetrating way from top to bottom, the lower end of the outer guide column penetrates through the female die to be fixedly connected with the lower gasket, and the support plate is arranged under the fixed piece and above the female die. The tooling for the FPC steel die is characterized by further comprising a push block, a spring device and a punch head, wherein the punch head is fixedly connected onto the back gasket through the fixed piece, the lower surface of the push block is provided with the spring device, and the push block is connected with the lower gasket by the spring device. According to the tooling for the FPC steel die, the perimeter of the die can be effectively reduced, the manufacture cost of the die can be reduced, and the stock utilization can be improved; and the die is designed into an ejection die from a blanking die, so that the problem that the blanking edge of a product is damaged in a pull way can be reduced.

Description

A kind of FPC punching block frock

Technical field

The utility model belongs to FPC Design of Dies field, particularly a kind of FPC punching block frock.

Background technology

Usually FPC is when Design of Dies, the mode (such as Fig. 3-4) of blanking die is adopted in the capital, cause easily the edge of product to be pulled, because product has the finger end, the tolerance that the finger end requires only has 0.05mm, and the making tolerance of mould itself is exactly 0.05mm, so the finger end of product must be out die-cut at first by mould, need to carry out altogether twice die-cut.The profile of the FPC mould that generally uses at present is jet-bedding, the girth of mould itself is long, cost of manufacture is higher, the jet-bedding diameter itself of desired product and the minimum 3.0mm(mould of product composing spacing is minimum simultaneously is 1.0mm), product composing quantity is just fewer, and the utilization rate of material is lower.

Summary of the invention

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of FPC punching block of the utility model frock, comprise master mold, rear pad, stator, lower gasket, supporting plate, outer guiding post, described master mold places on the lower gasket, described stator is arranged under the rear pad, described outer guiding post upper end is run through successively under upper and is connected and fixed sheet, rear pad and supporting plate, described outer guiding post lower end is run through master mold and is fixedly connected with lower gasket, described supporting plate is arranged under the stator, on the master mold, in addition, also comprise pushing block, spring assembly and drift, described drift is fixedly connected on the rear pad by stator, is provided with spring assembly below the described pushing block, and described pushing block connects lower gasket by spring assembly.

Further, the described supporting plate left and right sides is symmetrical arranged each two little guide pillar, and described master mold left and right sides symmetry respectively arranges two post holes, and described little guide pillar is corresponding one by one up and down with the post hole.

Further, be provided with spring leaf between described supporting plate and the stator.

Further, described drift is edge of a knife drift.

Further, establish screw in the described lower gasket, described screw upper end is connected with spring assembly, and the height of described pushing block and elastic force can be adjusted by screw.

The beneficial effects of the utility model: the utility model mold and punching head becomes the edge of a knife by jet-bedding, can effectively reduce the mould girth, reduce the Mold Making cost, the composing quantity of product also increases to some extent, increased stock utilization, mould is designed to eject mould by blanking die, has reduced the problem that product blanking edge is pulled.

The specific embodiment

The utility model is further described with reference to the accompanying drawings for the below:

Must form a loop during because of the drift cutting on line of mould, so the drift that new die design method designs is cuboid (such as Fig. 2), because Design of Dies is by jet-bedding 1(such as Fig. 1) change the edge of a knife 2 into, one-step punching requires to cut off product, so in the utility model drift cuboid one end is ground to form two R angles, reduce the tolerance that process of lapping produces, avoid the wearing and tearing of effective cutting part, form a die-cut breach, can die-cut stopping pregnancy product, guarantee that die-cut product out is complete.

Such as Fig. 5-7, a kind of FPC punching block of the utility model frock, comprise master mold 3, rear pad 4, stator 5, lower gasket 6, supporting plate 7, outer guiding post 8, described master mold 3 places on the lower gasket 6, described stator 5 is arranged under the rear pad 4, described outer guiding post 8 upper ends are run through successively under upper and are connected and fixed sheet 5, rear pad 4 and supporting plate 7, described outer guiding post 8 lower ends are run through master mold 3 and are fixedly connected with lower gasket 6, described supporting plate 7 is arranged under the stator 5, on the master mold 3, in addition, also comprise pushing block 9, spring assembly 10 and drift 11, described drift 11 is fixedly connected on the rear pad 4 by stator 5, be provided with spring assembly 10 below the described pushing block 9, described pushing block 9 connects lower gasket 6 by spring assembly 10.

Further, described supporting plate 7 left and right sides are symmetrical arranged each two little guide pillars 12, and described master mold 3 left and right sides symmetries respectively arrange two post holes 13, and described little guide pillar 12 is corresponding one by one up and down with post hole 13.

Further, be provided with spring leaf 14 between described supporting plate 7 and the stator 5.

Further, described drift 11 is edge of a knife drift.

Further, establish screw 15 in the described lower gasket, described screw 15 upper ends are connected with spring assembly 10, and the height of described pushing block 9 and elastic force can be adjusted by screw 15.
