Description

A kind of 3C electronic product cold punching die

Technical field

This utility model relates to technical field of mold, is specifically related to a kind of 3C electronic product cold punching die.

Background technology

Existing domestic or international 3C field aluminium or almag class NB appearance member, rely on CNC processing more, uses aluminum Plate, through multiple CNC processing procedures, expends longer man-hour, just can mold product, thus cause product cost higher, and production capacity is low, Whole development of manufacturing is had difficulty in taking a step.Conventional ones mould machine-shaping process is as it is shown in figure 1, mould cannot molding profit Angle, even if or use mould back to squeeze go out Li Jiao, due to drift insufficient strength back to squeeze, mould cannot be produced in batches, or product table Face due to after the stress trace sandblasting anode caused back to squeeze outward appearance cannot meet RD and client's esthetic requirement.

Summary of the invention

Goal of the invention: for the deficiencies in the prior art, this utility model provides a kind of 3C electronic product cold punching die, adds The product appearance that work goes out is excellent, good stability.

Technical scheme: 3C electronic product cold punching die described in the utility model, including upper die component, lower mold assemblies； Described upper die component includes upper bolster, train wheel bridge, cope match-plate pattern and upper de-plate the most successively, and described lower mold assemblies is from bottom to up Include die shoe, lower plate, lower de-plate, lower bolster successively, die shoe is provided with two low punches, low punch runs through lower plate, The most de-plate is connected with bottom lower bolster, and upper de-plate is the most corresponding with lower bolster, is equipped with the slide block that inclined-plane coordinates outside low punch, Slide block is connected with the lower edge of a knife, and the lower edge of a knife is just to lower bolster border.

Improving above-mentioned skill scheme further, described de-plate embeds in the middle part of described cope match-plate pattern, and described de-plate passes through liftout Pin is connected with described upper bolster.

Further, described lower plate is connected by jigger pin with described lower de-plate, and described lower plate is lower de-with described Plate keeps gap when non-punching press, eliminates gap after punching press puts in place.

Further, described die shoe is supported on bottom plate by bottom seat pad.

Further, described upper bolster, die shoe two ends are by inner guiding post, outer guiding post positioning and guiding.

Further, described low punch is that 55 ° of inclined-planes coordinate with described slide block.

Further, described lower bolster has line ball, and product takes off under plate coordinates with described lower bolster at line ball on described Position forms 70 ° of bendings, and after described cope match-plate pattern punching press puts in place, product de-plate described is formed under coordinating with described lower bolster 90 ° of bendings also complete side wall essence under the effect of the described lower edge of a knife and cut.

Beneficial effect: compared with prior art, advantage of the present utility model: this utility model is for 3C electronics techniques NB appearance member A class in field, D like members diel cannot molding Li Jiao, it is impossible to obtain the technical bottleneck of relatively low height of side wall, While meeting RD design, customer demand, design a mould, there is molded appearance excellent, it is ensured that after sandblasting, anodic process Exquisite appearance；Good stability, processing is efficiently.

Detailed description of the invention

Below by accompanying drawing, technical solutions of the utility model are described in detail.

Embodiment 1: the upper bolster 2 set gradually from top to bottom as shown in Figure 2 and Figure 3, train wheel bridge 3, cope match-plate pattern 5, upper de- Plate 4, lower bolster 15, lower bolster 1212, lower de-plate 11, lower plate 10, die shoe 9, upper bolster 2, die shoe about 9 are correspondingly arranged And by inner guiding post 1, outer guiding post 6 positioning and guiding, upper de-plate 4 embeds in the middle part of cope match-plate pattern 5, upper de-plate 4 is by jigger pin and upper mold Seat 2 is connected；Die holder is supported on bottom plate 7 by bottom seat pad 8, and lower plate 10 height is 20mm and height is the lower de-of 35mm Plate 11 is connected by jigger pin, and lower plate 10 keeps gap with lower de-plate 11 when non-punching press, and die shoe 9 is provided with under two Drift 13, low punch 13 run through lower plate 10, lower de-plate 11 is connected bottom lower bolster 15, upper de-plate 4 and lower bolster about 15 Correspondence, is equipped with the slide block 14 that 55 ° of inclined-planes coordinate outside low punch 13, slide block 14 is connected with the lower edge of a knife 16, and the lower edge of a knife 16 is the most right Lower bolster 15 border, lower bolster 15 has line ball, and product forms 70 ° in line ball position under upper de-plate 4 coordinates with lower bolster 15 Bending, after cope match-plate pattern 5 punching press puts in place, product shape bending in 90 ° at the lower edge of a knife 16 under upper de-plate 4 coordinates with lower bolster 15 Complete side wall essence under effect to cut.

By this utility model clamping on 110T open type punch press, process product relies on hole position with profile, is placed on down In template 15, as shown in Figure 4, upper de-plate 4 plays binder effect elder generation contact product appearance to punch press closing course, utilizes lower bolster 15 Doing and obtain nature profit angle effect after line ball realizes 70 ° of molding, after continuation punching press cope match-plate pattern 5 puts in place, product obtains 90 ° of molding, with This simultaneously low punch 1312 rely on what the power of vertical direction was converted to horizontal direction by 55 ° of gradients to try hard to recommend movable slider 14, slide block 14 Promoting the lower edge of a knife 16 to complete product side essence to cut, in order to reach perfect assembling effect, RD deisgn product height of side wall only has 0.44mm, uses and runs slide block 14 from inside to outside, and slide block 14 promotes 8 drifts 13 to be sequentially completed product side and completes from inside to outside 0.44mm height of side wall essence is cut.

Although as it has been described above, represented and described this utility model with reference to specific preferred embodiment, but it must not It is construed to the restriction to this utility model self.In the spirit and scope of the present utility model defined without departing from claims Under premise, can various changes can be made in the form and details to it.
