Description

A FPC steel mold tooling

technical field

The utility model belongs to the field of FPC mold design, in particular to an FPC steel mold tooling.

Background technique

Usually FPC adopts the method of blanking die when designing the mold (as shown in Figure 3-4), which is easy to cause the edge of the product to be strained, because the product has a finger end, the tolerance required for the finger end is only 0.05mm, and the production of the mold itself The tolerance is 0.05mm, so the finger end of the product must be punched out by the mold first, and a total of two punchings are required. The shape of the FPC mold commonly used at present is a punching groove, the circumference of the mold itself is relatively long, and the production cost is relatively high. At the same time, the required spacing between the product and the product typesetting is at least 3.0mm (the diameter of the punching groove of the mold itself is at least 1.0mm), The number of product layouts is relatively small, and the utilization rate of materials is low.

Contents of the invention

In order to solve the above technical problems, the utility model adopts the following technical solutions:

The utility model is an FPC steel mold tooling, comprising a master mold, a rear gasket, a fixed piece, a lower gasket, a supporting plate, and an outer guide column. The said female mold is placed on the lower gasket, and the said fixed piece is arranged on Under the rear gasket, the upper end of the outer guide column penetrates through the fixed piece, the rear gasket and the supporting plate sequentially from top to bottom, and the lower end of the outer guide column penetrates through the female mold and is fixedly connected to the lower gasket, and the supporting plate is arranged on Under the fixed sheet, above the female mold, in addition, it also includes a push block, a spring device and a punch, the punch is fixedly connected to the rear gasket through the fixed sheet, and a spring device is arranged under the push block, and the The push block is connected to the lower spacer through a spring device.

Further, two small guide pillars are symmetrically arranged on the left and right sides of the supporting plate, and two pillar holes are symmetrically arranged on the left and right sides of the mother mold, and the small guide pillars correspond to the upper and lower pillar holes one by one.

Further, a spring piece is arranged between the pallet and the fixing piece.

Further, the punch is a knife-edge punch.

Further, a screw is provided inside the lower gasket, and the upper end of the screw is connected with a spring device, and the height and elastic force of the push block can be adjusted through the screw.

Beneficial effects of the utility model: the mold punch of the utility model is changed from a punching groove to a knife edge, which can effectively reduce the circumference of the mold, reduce the cost of mold manufacturing, increase the number of layouts of the product, and increase the utilization rate of materials. The mold is designed to eject the mold, which reduces the problem of strain on the edge of the product blanking.

Detailed ways

The utility model will be further described below according to the accompanying drawings:

Because the punch of the mold must form a loop during online cutting, the punch designed by the new mold design method is a cuboid (as shown in Figure 2), because the design of the mold is changed from punching groove 1 (as shown in Figure 1) to knife edge 2, once Punching requires that the product cannot be cut, so in the utility model, one end of the cuboid of the punch is ground into two R angles, which reduces the tolerance generated during the grinding process, avoids the wear of the effective cutting part, forms a punching gap, and does not punch and cut the product. Ensure the integrity of the punched products.

As shown in Figure 5-7, a FPC steel mold tooling of the utility model includes a master mold 3, a rear gasket 4, a fixed piece 5, a lower gasket 6, a supporting plate 7, and an outer guide column 8. On the lower gasket 6, the fixed piece 5 is arranged under the rear gasket 4, and the upper end of the outer guide post 8 runs through and connects the fixed piece 5, the rear gasket 4 and the supporting plate 7 sequentially from top to bottom, so that The lower end of the outer guide column 8 passes through the female mold 3 and is fixedly connected to the lower gasket 6. The supporting plate 7 is arranged under the fixed piece 5 and above the female mold 3. In addition, it also includes a push block 9, a spring device 10 and a punch. 11. The punch 11 is fixedly connected to the rear gasket 4 through the fixing piece 5 , a spring device 10 is arranged under the push block 9 , and the push block 9 is connected to the lower gasket 6 through the spring device 10 .
